状语从句的时态特点一般情况下
状语从句的时态特点一般情况下，时间和条件状语从句的谓语动词一般用“一般现在时”表示“一般将来时”，用“现在完成时”表示“将来完成时”。例如：
I will call you as soon as I arrive in Beijing. 我一到北京就给你打电话。（这是由as soon as引导的时间状语从句，从句中的谓语动词arrive是一般现在时，表示一般将来时，决不可用will arrive）
As soon as I have finished this work, I will go home. 我一完成此工作，就回家。（从句中的谓语动词用现在完成时have finished，表示将来完成时,决不可用will have finished）If he comes back, please let me know.如果他回来了，请通知我。（从句中的谓语动词用comes back,表示一般将来时，决不可用will come back）
状语从句讲解和练习
状语修饰动词、形容词、副词或整个句子。通常由副词、介词短语、动词不定式、分词和从句等担当。例如：
1. Naturally , our grandparents were pleased to get our phone call . (副词)
2. We worked hard , from sunrise to sunset . (介词状短语)
3. To help my disabled aunt , I spend an hour working in her house every day . (不定式)
4. Seen from a distance , the farmhouse looked deserted . (过去分词)
5. I know how to light a camp fire because I had done it before .（原因状语从句）
状语的位置比较灵活，可以位于句首、句末或句中。enough用作状语修饰形容词和副词时必须后置。
状语从句主要用来修饰主句或主句的谓语。一般可分为九大类，分别表示时间、地点、原因、目的、结果、条件、让步、比较和方式。尽管种类较多，但由于状语从句与汉语结构和用法相似，所以理解和掌握它并不难。状语从句的关键是要掌握引导不同状语从句的常用连接词
和特殊的连接词即考点。现分别列举如下:
1．时间状语从句

10. 状语从句的简化
?状语从句的省略
状语从句同时具备下列两个条件:①主句和从句的主语一致，或从句主语为it；②从句主要动词是be的某种形式。从句中的主语和be动词常可省略。例如：
When ( the museum is ) completed , the museum will be open to the public next year .
He’ll go to the seaside for his holiday if (it is ) possible.
另外，比较状语从句经常省略。例如：
I’m taller than he (is tall ).
The higher the temperature (is), the greater the pressure (is ).
就状语从句而言,有时为了使语言言简意赅,常常将状语从句进行"简化"。状语从句的"简化"现象在口语中较为普遍,而且在高考中的复现率也较高。因此,有必要对其进行全面、透彻的了解。
状语从句的"简化"现象常存在于以下五种状语从句中:①由if, unless等引导的条件状语从句;②由although, though, even if / though等引导的让步状语从句;③由when, while, as, before, after, until / till等引导的时间状语从句;④由as, as if等引导的方式状语从句;⑤由as, than等引导的比较状语从句。下面针对这五种情形作一归纳。
(1)当状语从句的主语是it,且谓语动词是be时,it和be要完全简化掉。例如:
If (it is) possible, he will help you out of the difficulty.如果可能的话,他会帮你摆脱困境。
You must attend the meeting unless (it is) inconvenient to you.除非情况对你来说不方便,否则你必须出席这次会议。
(2)当状语从句的主语和主句的主语一致时,从句可以将主语和be动词简化掉。常用于以下几种情形:
a.连词+形容词
As (he was) young, he learned how to ride a bike.他小时候就学会了骑自行车。
Whenever (she is) free, she often goes shopping.她有空就去逛商店。
Work hard when (you are) young, or you'll regret.少壮不努力,老大徒伤悲。
b.连词+名词
While (he was) a young boy, he was always ready to help others.他在孩提时代就乐于助人。
Although (he was) a farmer, now he is a famous director.尽管他曾是个农民,而现在是位著名的导演了。
c.连词+现在分词
As (she was) walking along the river bank, she was singing a pop song.她沿着河堤边走边唱着流行歌曲。
Although (he is) doing his best in maths these days, he has still got no good marks.尽管近来他一直在学数学,但他仍然没有取得好成绩。
d.连词+过去分词
He won't go there with us unless (he is) invited.除非受到邀请,否则他不会和我们一道去那里。
The concert was a great success than (it was) expected.这场音乐会出乎意料地取得
了巨大成功。
e.连词+不定式
He stood up as if (he were) to say something.当时他站起来好像要说什么。He wouldn't solve the problem even if (he were) to take charge.即使他来负责,他也解决不了这个问题。
f. 连词+介词短语
She looked anxious as though (she was) in trouble.她看上去很焦急,好像遇到了麻烦。
He had mastered the English language before (he was) in the USA.他到美国之前就懂英语了。
注意:当从句主语和主句主语不一致时,从句部分要么用完全形式,要么用独立主格结构来表达。例如:
When the meeting was over, all the people went out of the meeting-room.当会议结束时,人们都走出了会议室。(=The meeting over, [编辑本段]
一、时间状语从句要点: 时间状语从句，由以下连词引导：
when while as after before as soon as since till /until by the time 在时间状语从句中，要注意时态一致。一般情况下主句是将来时的时候，从句要用一般现在时。
1.when当...的时候
Mozart started writing music when he was four years old.
(当)莫扎特4岁的时候，开始写音乐作品。
2.while当...时

前几天做完作业之后回的家。
5.before 在...之前

我们一到那就开始工作。
I will write to you as soon as I get home.
我一到家就给你写信。
7.since 自。。。以来到现在
表示自过去的一个起点时间到目前(说话时间)为止的一段持续时间。主句一般用现在完成时，从句用一般过去时。
Mr Green has taught in that school since he came to China three years ago.
自格林先生来中国以来，他就在这所学校教书。
(还可以用作介词，本句从句还可以用短语：since three years ago(自三年前以来)表示。)
8 till /until
都可以作连词，连接时间状语，也可以作介词，与其它词构成介词短语，在句中作状语。
They walked till /until it was dark.
他们一直走到天黑。
Xiao Ming didn’t leave home till / until his father came back.
小明直到他爸爸回来才离开家。
9. by the time 到。。。为止(所在句子的主句应用完成时)
By the time he gets there , his father has already gone.
他到家的时候，他爸爸已经走了。
By the time I got to school, the class had already began.
我到校时，已经开始上课了。
时间状语从句（adverbial clause of time）
1.由when, while, as引导的时间状语从句。例如：
When you think you know nothing, then you begin to know something.当你以为自己一无所知的时候，你就是在开始知道一些事物了。
When truth is buried under the ground it grows, it chokes, it gathers such an explosive force that on the day it bursts out , it blows up everything with it.当真理被埋在地下的时候，它在生长，它感到压抑，它蓄存着这么一种爆炸性力量，一旦冒出，它就会炸破一切！

You can feel the air moving as your hand pushes through it. 当你的手在空气中挥动的时候，你就能感觉到空气在流动。
Our headmaster laughed as she spoke.我们的校长边谈边笑。
when, while和as的区别
when引导的从句的谓语动词可以是延续性的动词，又可以是瞬时动词。并且when有时表示“就在那时”。
例如：
When she came in, I stopped eating.她进来时，我在吃饭。(瞬时动词)
When I lived in the countryside, I used to carry some water for him.当我住在农村时，我常常为他担水。（延续性的动词）
We were about to leave when he came in.我们就要离开，就在那时他进来了。
While引导的从句的谓语动作必须是延续性的，并强调主句和从句的动作同时发生（或者相对应）。并且while有时还可以表示对比。例如：
While my wife was reading the newspaper, I was watching TV. (was reading是延续性的动词，was reading和was watching同时发生)
I like playing football while you like playing basketball.我喜欢踢足球，而你喜欢打篮球。（对比）
As表示“一边……一边”，as引导的动作是延续性的动作，一般用于主句和从句动作同时发生；as也可以强调“一先一后。例如：
We always sing as we walk.我们总是边走边唱。（as表示“一边……一边”）
As we was going out, it began to snow.当我们出门时，开始下雪了。（as强调句中两个动作紧接着先后发生，而不强调开始下雪的特定时间）
as when while的辨析
as when while都表示主、从句动作同时发生，三者差异如下：
表示“一边。。。一边＂的意思
as 强调两个动作同时进行，并表示对比时
用于发生时间较短时
when
1、还可以表示从句动词的动作在主几句动词的动作＂之前＂或＂之后＂发生。
2、when＝and then; at that moment (正在那个时候)
while 1、用于时间较长时
2、强调两个动作同时进行，并表示对比时
有时这三个连词可以互换，有时不可以。
lIt was raining hard when (as) I got there.
我到那里时，正在下大雨。( 动作同时发生，when可换为as, 但不能换为while，因为get是点动词.)
lWhen I had read the article, he called me.
我看完这篇文章之后，她给我打了电话。( 从句动作发生在主句之前，注意时态表达，只能用when )
lWhen I got to the cinema, the film had begun.
(当)我到了电影院时，电影已经开演了。(从句的动作发生在主句之后，只能用when,并要注意时态)
lHe was about to leave, when the telephone rang.
他正要离开，忽然电话响了。( 此时不能放在句首。主句动词一般表达“正在” “即将”.
while, as不能代替
lShe thought I was talking about her daughter, while, in fact, I was talking about my daughter.
他以为我在谈她女儿，然而，实际上在谈论我女儿。(表转折，对比，when, as都不能代替它)
lWhile the alien was buying a souvenir, the girl called the police.
外星人买纪念品时，那女孩给警察打了电话。(表示主句，从句的动作同时发生，while 后引导的状语从句的动词必须是延续动词不能是点动词，因为它表示较长时间) lMother was worried because little Alice was ill, especially as (when/ while) father was away.
妈妈担心，因为小爱丽丝病了，特别是他父亲不在家的时候。(此时as ,when, while可通用)
2.由before和after引导的时间状语从句。
注意before引导的从句不再用否定式的谓语，并且当before引导的从句位于主句之后，有时译成“就，才”。还要注意主句和从句之间的时间关系。当主句用将来时，从句总是用现在时；如果before引导的从句谓语用的是过去时，则主句动词多用过去完成时，这样以便体现动作发生的先后。After表示主句动作发生在从句动作之后。主句和从句的动作的时间关系正好与before引导的从句相反。例如：
It will be four days before they come back. 他们要过四天才能回来。
Einstein almost knocked me down before he saw me.爱因斯坦几乎把我撞倒才看到我。
My father had left for Canada just before the letter arrived.我父亲恰好在信到之前去加拿大了。
They had not been married four months before they were divorced. 他们结婚还不到四个月就离婚了。
After you think it over, please let me know what you decide.你仔细考虑过以后，告诉
我你是怎样决定的。
After we had finished the work, we went home.完成工作之后，我们回家了。（从句用过去完成时，主句用一般过去时）
3.由till或until引导的时间状语从句。
till和until一般情况下两者可以互换，但是在强调句型中多用until。并且要注意的是：如果主句中的谓语动词是瞬时动词时，必须用否定形式；如果主句中的谓语动词是延续性动词时，用肯定或否定形式都可以，但表达的意思不同。例如：
I didn't go to bed until（till）my father came back.直到我父亲回来我才上床睡觉。
It was not until the meeting was over that he began to teach me English.直到散会之后他才开始教我英语。
I worked until he came back.我工作到他回来为止。
I didn't work until he came back.他回来我这才开始工作。
Please wait until I arrived.在我到达之前请等我。
4.由since引导的时间状语从句。
since引导的从句的谓语动词可以是延续性的动词，又可以是瞬时动词。一般情况下，从句谓语动词用一般过去时，而主句的谓语动词用现在完成时。但在It is ＋时间＋since从句的句型中，主句多用一般现在时。例如：
I have been in Beijing since you left. 自从你离开以来，我一直在北京了。
Where have you been since I last saw you? 自上次我和你见面以后，你到哪里去了？
It is four years since my sister lived in Beijing. 我妹妹不在北京住有四年了。
It is five months since our boss was in Beijing.我们老板离开北京有五个月了。
知识扩展
1. It is since从。。。以来多长时间了(因为since +从句或名词，表示一段时间)
It is five years since we met last time.从我们上次见面已经五年了。
2. It is +before…(。。。才)
It was a long time before I went to sleep again.
过了很长时间我才睡着。
It was an hour before(＝until) the police arrived.
过了一个小时，警察才来。
5.由as soon as, immediately, directly, instantly, the moment, the instant, the minute, 等引导的时间状语从句。这些连词都表示“一……就”。例如：
I will go there directly I have finished my breakfast. 吃完早饭，我立即到那里去。
The moment I heard the news, I hastened to the spot.我一听到消息，马上赶到了出事地点。
As soon as I reach Canada, I will ring you up. 我一到加拿大，就给你来电话。
【注意】hardly(scarcely, rarely)…when / before, no sooner…than相当于as soon as 之意。主句用过去完成时，从句用一般过去时。当hardly, scarcely, rarely和no sooner位于句首时，主句应用倒装语序。例如：
He had no sooner arrived home than he was asked to start on another journey. 他刚到家，就被邀请开始另一旅程。
No sooner had the sun shown itself above the horizon than he got out of bed to commence work.太阳刚从地平线上升起，他就起床劳动去了。
Hardly had I sat down when he stepped in.我刚坐下，他就进来了。
He had hardly fallen asleep when he felt a soft touch on his shoulder.这个阿拉伯人刚
要入睡就感到肩膀上被轻轻一触。
6.由by the time引导的时间状语从句。
注意时态的变化：在一般情况下，如果从句的谓语动词用一般过去时，主句的谓语动词用过去完成时；如果主句的谓语动词用一般现在时，主句的谓语动词用将来完成时。例如：By the time you came back, I had finished this book.到你回来时，我已经写完这本书了。
By the time you come here tomorrow, I will have finished this work. 你明天来这儿的时候，我将已经完成此工作了。
7.由each time, every time和whenever引导的时间状语从句。例如：
Each time he came to Harbin, he would call on me. 他每次来哈尔滨，总是来看我。
Whenever that man says“To tell the truth”, I suspect that he's about to tell a lie.每当那个人说“说实在话”的时候，我猜想他就要说谎了。
You grow younger every time I see you. 每次遇到你，见你更年轻了。
8.由as long as和so long as引导的时间状语从句。这两个连词表示“有多久……就多久”。例如：
You can go where you like as long as you get back before dark. 你可以随意到哪里去，只要在天黑以前回来就行。
I will fight against these conditions as long as there is a breath in my body! 只要我一息尚存，我就要反对这种境况。[编辑本段]
二地点状语从句地点状语从句(adverbial clause of place)
地点状语从句一般由连接副词where, wherever等引导，已经形成了固定的句型，
要点: 由连词where和复合关系词wherever (=no matter where )引导.
例如：
句型1：Where＋地点从句，（there）＋主句。
【注意】此句型通常译成“哪里……哪里就……”；主句在从句后面时，there可用可不用；如果主句在从句的前面时，一般都不用there。例如：
Where there is no rain, farming is difficult or impossible.在没有雨水的地方，耕作是困难的，或根本不可能的。
They were good persons. Where they went, there they were warmly welcomed. 他们都是好人。因此他们走到哪里都受到热烈欢迎。
You should have put the book where you found it. 你本来应该把书放回原来的地方。
Where the Communist Party of China goes, there the people are liberated.哪里有了中国共产党，哪里人民得解放。
句型2：Anywhere/ wherever＋地点从句，＋主句。
【注意】anywhere本身是个副词，但是，常可以引导从句，相当于连词，意思相似于wherever, anywhere引导的从句可位于主句之前，也可以位于主句之后。而wherever本身就是个连词，表示“在何处，无论何处”。例如：
Wherever the sea is , you will find seamen.有海就有海员。
知识扩展
1.Where there is a will , there is a way.
有志者事竟成。(谚语)
1.It will be mixed school where not all the children are disabled.
他将是一所混合式学校，那里的儿童并不都是残疾。(在限定性定语从句中对限先行词起限定作用。)
2.Wherever you go , I go too.
无论你到什么地方，我都去。(wherever=no matter where)无论何处，多用于句首。
3.Wherever there is smoke , there is fire.
无风不起浪。(谚语)
4. While she was wondering where to go , she met a policeman.
疑问副词where后跟不定式,构成不定式短语. [编辑本段]
三、条件状语从句要点：表示状语从句由连词if, unless (=if not) 引导。
1.If it doesn’t rain tomorrow, we will go hiking.
如果明天不下雨, 我们就去远足.
2.You will get good grades if you study hard.
如果你努力学习,就会取得好成绩.
3.I will go to the party unless he goes there too.
我不会去参加聚会的, 除非他也去.(如果他不去,我也不去.)
4.You will be late unless you leave immediately.
如果你不马上走,你将会迟到的.(=If you don’t leave immediately, you will be late.)
难点提示：用条件状语从句时要注意时态的正确使用,当主句是将来时的时候,从句要用一般现在时.
lHe will not leave if it isn’t fine tomorrow.
一般将来时，一般现在时
lThey are going to have a picnic if it doesn’t rain next week.
一般将来时, 一般现在时[编辑本段]
四、原因状语从句要点: 由连词because, since, as引导, 也可由for, now that 等词引导
1.I didn’t go to school yesterday because I was ill.
我昨天没去上学，因为我生病了。
2. Since everybody is here, let’s begi n our meeting.
既然大家都来了, 让我们开始开会吧.
3. As you are in poor health, you should not stay up late.
既然你身体不好, 你就不该熬夜.
4.I asked her to stay to tea, for I had something to tell her.
我请她留下来喝茶,因为我有事要告诉她.
.难点——because , since , as , for,辨析
1）because语势最强，用来说明人所不知的原因，回答why提出的问题。当原因是显而易见的或已为人们所知，就用as或since。
I didn’t go, because I was afraid.
Since /As the weather is so bad, we have to delay our journey.
2）由because引导的从句如果放在句末，且前面有逗号，则可以用for来代替。但如果不是说明直接原因，而是多种情况加以推断，就只能用for。
He is absent today, becaus e / for he is ill.
He must be ill, for he is absent today. [编辑本段]
五、目的状语从句要点：目的状语从句由连词that, so that, so…that , in order that 引导。
1.so that 以至, 以便
I’ll run slowly so that y ou can catch up with me. (目的)
我将慢慢跑以至你能赶上我。
I opened the window so that fresh air might come in. (目的)
我把窗户打开以使新鲜空气可以进来。
2.in order that=so that:为了
We shall let you know the details soon in order that you can/may make your arrangements.
不久我们将会让你知道详情,以便你们能够做出安排。(目的) [编辑本段]
六、结果状语从句要点：结果状语从句由连词( so )that, so…that, such…that, so much/many…that引导。
1.so…that 如此…以至于
The scientist’s report was so instructive that we were all very ex cited.
科学家的报告很有启发性，我们感到很兴奋。
He always studied so hard that he made great progress.
他总是那么努力，结果他取得了很大的进步。
2. such…that 如此。。。以至
It’s such nice weather that all of us want to go to the park.
天气是如此的好，我们大家都想去公园玩。
3.比较：so和such
其规律由so与such的不同词性决定。such 是形容词，修饰名词或名词词组，so 是副词，只能修饰形容词或副词。so 还可与表示数量的形容词many, few, much, little(这四个形容词表多或表少时)连用，形成固定搭配。
so foolish such a fool
so nice a flower such a nice flower
so many / few flowers such nice flowers
so much / little money. such rapid progress
so many people such a lot of people
（so many 已成固定搭配，a lot of 虽相当于many，但 a lot of 为名词性的，只能用such搭配。）
so…that与such…that之间的转换既为so与such之间的转换。
The boy is so young that he can’t go to school.
He is such a young boy that he can’t go to school
难点
+形容词或副词
+形+a(an)+单数可数名词
so +many 或few+复数可数名词+that
+much或little+不可数名词
so that ,such…that 都可以in order that两者皆可引导目的地状语从句和结果状语从句，
当他们引导目的状语从句时，从句的谓语里常常有can, could, may, might, will, would 等次。
so +adj或adv.+ that，such +n.+ that 以上两种句型都表示结果,其中so为副词,后接形容词，副词原型，当可数名词前有many, few；不可数名词前有much, little修饰时，应采用句型：so many (few, much, little )+n. 。such为形容词, 后只能接名词。这名词既可以地可数的，也可以是不可数的。如果这名词是可数,单数,则必须在名词前加冠词a(an). 常见
的形式是:such a (beautiful)garden, such(nice)people.
1。I’ve had so many falls that I’m bla ck and blue all over.
我跌了很多跤，浑身数摔得清一块紫一块.
2。there are so few notebooks that I can’t give you any.
笔记本太少了,我一本也给不了你.
3。It is such nice weather that I’d like to take a walk.
天气是如此只好,以至于我想去散散步.
4。Mike is so honest a man that we all believe him.
麦克是如此诚实的一个人,以至于大家都相信他
(=Mike is such an honest man that we all believe him.)
5。The weather is so nice that I’d like to take a walk.
天气是如此只好,以至于我想去散散步. [编辑本段]
七、让步状语从句要点: 表示让步的状语从句由连词though, although引导.
难点：
lthough, although当虽然讲, 都不能和but连用. Although,(though)…but的格式是不对的.但是他们都可以同yet (still) 连用. 所以thought (although)…yet(still)的格式是正确的.
Wrong: Although he is rich but he is not happy.
Right : Although he is rich, yet he is not happy.
虽然他很富有, 然而他并不快乐.
Right : Although we have grown up, our parents treat us as children.
Right : Although we have grown up, our parents still treat us as children.
尽管我们已经长大了,可是我们的父母仍把我们看作小孩.
although, though 辨析
although 不能though 那样用作副词, 放在句末表示强调时要用even though.
1。He is looking fit, though.
但是,他看上去很健康. 考点
2。Even though I didn’t under a word, I kept smiling.
尽管我一个字也不懂，我还是一直微笑着。
3。He is quite experienced, he is young, though.
尽管他很年轻，他很有经验。
典型例题
1）___she is young, she knows quite a lot.
A. When
B. However
C. Although
D. Unless
答案：C。意为虽然她很年轻，却知道许多。
2)as, though 引导的倒装句
as / though引导的让步从句必须表语或状语提前（形容词、副词、分词、实义动词提前）。
Child as /though he was, he knew what was the right thing to do.
= Though he was a small child, he knew what was the right thing to do.
注意：
a.句首名词不能带任何冠词。
b.句首是实义动词，其他助动词放在主语后。如果实义动词有宾语和状语，随实义动词一起放在主语之前。
Try hard as he will, he never seems able to do the work satisfactorily.
= Though he tries hard, he never seems…
虽然他尽了努力，但他的工作总做的不尽人意。
3)ever if, even though.即使
We’ll make a trip even though the weather is bad.
4) whether…or-不管……都
Whether you believe it or not, it is true.
5)"no matter +疑问词" 或"疑问词+后缀ever"
No matter what happened, he would not mind.
Whatever happened, he would not mind.
替换：no matter what = whatever
no matter who = whoever
no matter when = whenever
no matter where = wherever
no matter which = whichever
no matter how = however
注意：no matter 不能引导主语从句和宾语从句。
（错）No matter what you say is of no use now.
（对）Whatever you say is of no use now.
你现在说什么也没用了。(Whatever you say是主语从句)
（错）Prisoners have to eat no matter what they’re given,
（对）Prisoners have to eat whatever they’re given.囚犯们只能给什么吃什么。[编辑本段]
八、比较状语从句要点：比较状语从句主要运用于形容词和副词的原级，比较级及最高级的句子之中。
原级
1. as…as 和。。。一样
Jack is as tall as Bob.
捷克和汤姆一样高。
2. not so(as)…as …和不一样
She is not so(as)outgoing as her sister.
她不如她姐姐外向。
比较级
more…than (更)
This book is more instructive than that one.
这本书比那本书由教育意义。
最高级
1.The most…in/of
This book is the most interesting of the three.
这本书是三本中最有趣的。
2. the + 形容词+est…of/in
This road is the busiest street in our city.
这条路是我们城市最繁忙的街道。
知识扩展
no more than只不过(嫌少的意思)
1。I have no more than two pens.
我只有两支笔。
2。It’s no more than a mile to the shops.
去商店不过一英里。
not more than不如。。。；(前者不如后者)
1。Jack is not more diligent than John.
捷克不如约翰勤奋。
2。one of the + 名词(复数)….之一(用于最高级)
Han Mei is one of the best students in our school.
韩梅是我们学校最好的学生之一。[编辑本段]
九、方式状语从句方式状语从句通常由as, (just) as…so…, as if, as though引导。
1）as, (just) as…so…引导的方式状语从句通常位于主句后，但在(just) as…so…结构中位于句首，这时as从句带有比喻的含义，意思是"正如…"，"就像"，多用于正式文体，例如：
1。Always do to the others as you would be done by.
你希望人家怎样待你，你就要怎样待人。
2。As water is to fish, so air is to man.
我们离不开空气，犹如鱼儿离不开水。
3。Just as we sweep our rooms, so we should sweep backward ideas from our minds.
正如打扫房屋一样，我们也要扫除我们头脑中落后的东西。
2）as if, as though
两者的意义和用法相同，引出的状语从句谓语多用虚拟语气，表示与事实相反，有时也用陈述语气，表示所说情况是事实或实现的可能性较大。汉译常作"仿佛……似的"，"好像……似的"，例如：
1。They completely ignore these facts as if (as though) they never existed.
他们完全忽略了这些事实，就仿佛它不存在似的。（与事实相反，谓语用虚拟语气。）2。He looks as if (as though) he had been hit by lighting.
他那样子就像被雷击了似的。（与事实相反，谓语用虚拟语气。）
3。It looks as if the weather may pick up very soon.
看来天气很快就会好起来。（实现的可能性较大，谓语用陈述语气。）
说明：as if / as though也可以引导一个分词短语、不定式短语或无动词短语，例如：1。He stared at me as if seeing me for first time.
他目不转睛地看着我，就像第一次看见我似的。
2。He cleared his throat as if to say something.
他清了清嗓子，像要说什么似的。
3。The waves dashed on the rocks as if in anger.
波涛冲击着岩石，好像很愤怒。[编辑本段]
十、状语从句在写作中的运用写作中能合理、正确地使用状语从句，不但能地道的表达英文习惯，而且还能使文体结构更加严谨、美观。例如下文：
My hobby
The hobby I enjoy most is fishing.
I started fishing (1)when I was five years old. I’ll never forget the day (2)when my father first took me fishing with him. On that day, I was holding a fishing rod (3)when a fish suddenly started pulling on the line. (4)I was so shocked that I fell into the water. But
experience didn’t put me off and I have been fishing ever since.
Now I still go fishing with my father. And we often go out on Sundays and spend the whole day fishing in the river.
(1)是由when引导的时间状语从句，这类从句的使用频率很高。
(2)句是由I’ll never forget the day .及when my father first took me fishing with him.两局组成。When在从句中做时间状语。
(3)句也是由when 引导的时间状语从句。When 常与suddenly 连用，主句常用过去进行是。译为“正在……, 忽然……”.
(4)是以so…that… (太…..以直于……)引导的结果状语从句.

主从句的时态问题
主从句的时态问题
从句和主句中谓语动词的时态 在复合句中，主句和从句的谓语动词时态一般遵循以下的规律： 一① 在以下三种主语从句中，主语从句的谓语动词要用“should+动词 原形”， should可省略。 (1)It is+形容词+that…句型。常见的形容词有important, necessary, natural, funny, strange, surprising, astonishing(令人惊讶的)等。 (2) It is +名词+that…句型。常见的名词有pity, shame, advice, suggestion, proposal(提议，建议)， requirement, request, desire, order 等。 (3) It is+动词的过去分词+ that…句型。常见的动词有advise, order, propose, request, suggest, demand, require等。 ②在insist(坚持)， urge (催促)， order(命令)， command(命令)，suggest(建议)，advise(建议)，recommend(建议，推荐)， request(请求，要 求)， demand(要求)，require(要求，需要)等动词后的宾语从句中，谓语动词用“should+动词原形”， should可省略。 ③ 在含有advice, order, demand, proposal(提议)， requirement, suggestion等名词的表语从句、同位语从句中，谓语动词用“should+动词原形”，should可省略。 ④在一些表示惊讶、意志等感情色彩的名词性从句中，谓语动词用“should+动词原形”或“should +have done”，译为“竟然，居然”。例如： I am surprised /shocked that you should speak in such a way。 I find it astonishing that he should be so rude to his mum。 It is strange /surprising that she should not have been invited。 I am glad that your story should have won the first prize。

名词性从句、定语从句、状语从句时态问题
一、名词性从句 （一）在宾语从句中主句和从句之间的时态的一致关系,通常由主句谓语的时态决定从句谓语的时态. ⒈若主句谓语动词是现在时或将来时,如：一般现在时,现在完成时,一般将来时,将来完成时等,从句可以根据需要使用任何时态. 如:He says that he is doing well in his lessons.you will miss a lot of lessons.the boy is lazy.XiaoWang was late for school yesterday.Jim has been back for two days. ⒉若主句谓语动词是过去时态(一般过去时,过去进行时,过去完成时,过去将来时,过去将来完成时),从句谓语动词也必须是过去时态. 如:He said he enjoyed himself last Sunday.he hadn’t bought any present.the would come back the next day.he was doing his homework· ⒊当从句表示客观事物或真理,或人们已经公认的道理时,其时态不受主句谓语动词的时态的影响.即使主句谓语动词使用了过去时的某种时态,从句的时态仍然是现在的某种时态. 1)The teacher said the earth goes around the sun。 2)He said the sun rises in the east. 3)His father said he gets up at six o'clock every morning. 4)He told me the light travels faster than the sound. ⒋当从句表示并未出现或尚未实现的愿望时,必须用过去时态. ⒌（可包含在1/2中）有些形容词后面可跟有从句,这种从句一般可看作宾语从句,其谓语也应与主句谓语的时态保持一致.可跟这种宾语从句的形容词有：afraid,glad,sure,confident,sorry, certain,conscious,aware等.一致的原则与宾语从句相同. 例如： I'm confident that I'll pass the exam.我有信心通过考试. He was lucky that he wasn't killed.他很幸运没有被杀死. （二）在主语从句,表语从句和同位语从句中,主句和从句之间的时态一致关系所遵守的法则和宾语从句相同. 例如： It appears that some little trouble was caused by a woman,whose name has not been ascertained.看来这件小小的麻烦是由一个至今尚不清楚其姓名的女人所引起的. It was known long ago that Professor Einstein played a key role in the development of the theory of relativity.人们早已知道,爱因斯坦教授对相对论的发展起了关键作用. It was proved centuries ago that the speed of light is186,000miles a second.几世纪前就证实了光的速度为每秒186,000英里. The fact[that man would soon be able to visit the moon]built up new scientific interest in earth's nearest neighbor.人类不久可以游览月球的事实,引起了对地球最近邻居的新的科学兴趣.二、定语从句与主句的时态一致关系 定语从句的时态不受影响意思就是定语从句的时态是根据事物真实发生的情景决定不受主句影响,因为定语从句的作用只是在修饰句子中的名词之类的,和句子本身的时态没有关系.比如： He is a man whose telephone was stolen.他是那个手机被偷的那个人. 主句一般现在时,从句过去时,因为手机真实被偷是在过去发生. I went to the apartment in which Mary lives in.我去过Mary现在住的房子. 主句过去式,从句一般现在时,因为我去过的那个房子,Mary确实现在在住. ⒈若定语从句的谓语表示的动作和主句谓语表示的动作同时发生,则要求使用同样的时

A．when B．as C．while D．before 【答案】B 【解析】 【详解】 句意：她在黑暗中走着，不时回头看看。考查连词辨析。when，while都可表示“…… 时候”；when引导的从句，谓语动词既可以是延续性动词，也可以是非延续性动词；while引导的从句，谓语动词必须是延续性动词，而不能是非延续性动词；as表示“在……期间”“随着”；before“在……之前”，常与过去时，一般现在时等连用。根据句意语境，可知她一边走一边回头看，as切合句意，故选B。 2．Tony has had to cook by himself ________ his mother went on business to Guangzhou. A．since B．after C．during D．when 【答案】A 【解析】 【详解】 句意：自从妈妈去广州出差以来，托尼不得不自己做饭。A. since从……以来；B. after在……之后；C. during 在……期间；D. when当……时候。since后跟时间状语从句时，表示的是到目前为止的时间段，从句时态为一般过去时，而主句的时态为现在完成时，故正确答案为A。 3．Our eyesight will become poorer and poorer we keep playing with phones. A．though B．unless C．if 【答案】C 【解析】 【详解】 句意：如果我们继续玩手机，我们的视力会越来越差。 A. though尽管，虽然； B. unless除非； C. if如果。这里是if引导的条件状语从句，遵循主句用一般将来时，从句用一般现在时态，根据题意，故选C。 4．WeChat Pay makes our lives confident. ______ we want to pay for something, we just need to scan a QR code（扫描二维码）.
引导的时间状语从句
1.由when, while, as引导的时间状语从句。 When you think you know nothing, then you begin to know something.当你以为自己一无所知的时候，你就是在开始知道一些事物了。When truth is buried under the ground it grows, it chokes, it gathers such an explosive force that on the day it bu rsts out , it blows up everything with it.当真理被埋在地下的时候，它在生长，它感到压抑，它蓄存着这么一种爆炸性力量，一旦冒出，它就会炸破一切！ Strike while the iron is hot. 趁热打铁。 Will you watch my clothes while I have a swim? 我游泳的时候，请你照看一下我的衣服。 You can feel the air moving as your hand pushes through it . 当你的手在空气中挥动的时候，你就能感觉到空气在流动。 Our headmaster laughed as she spoke.我们的校长边谈边笑。 when, while和as的区别 1. when引导的从句的谓语动词可以是延续性的动词，又可以是瞬时动词。并且when有时表示“就在那时”。 例如： When she came in, I stopped eating.她进来时，我在吃饭。(瞬时动词) When I lived in the countryside, I used to carry some wate r for him.当的住在农村时，我常常为他担水。（延续性的动词） We were about to leave when he came in.我们就要离开，就在那时他进来了。 2. While引导的从句的谓语动作必须是延续性的，并强调主句和从句的动作同时发生（或者相对应）。并且while有时还可以表示对比。例如： While my wife was reading the newspaper, I was watching TV. (was reading是延续性的动词，was reading和was watching同时发生) I like playing football while you like playing basketball.我喜欢踢足球，而你喜欢打篮球。（对比） 3. As表示“一边……一边”，as引导的动作是延续性的动作，一般用于主句和从句动作同时发生；as也可以强调“一先一后。例如： We always sing as we walk.我们总是边走边唱。（as表示“一边……一边”） As we was going out, it began to snow.当我们出门时，开始下雪了。（as强调句中两个动作紧接着先后发生，而不强调开始下雪的特定时间） as when while的辨析 as when while都表示主、从句动作同时发生，三者差异如下：
状语从句。主谓一致。几种时态转换
中考英语语法：状语从句时态类型 1、时态说明 1）在时间和条件状语从句中，通常要用一般现在时表示将来意义，不能直接使用将来时态： I won’t go if it rains tomorrow. 要是明天下雨，我就不去。(不能用will rain) 2）有时也可见到if you will 这样的说法，但那不是将来时态，而是表示意愿或委婉的请求(此时的will是情态动词)： If you will wait a moment, I’ll fetch the money. 请等一下，我就去拿钱。 2、常见类型 状语从句即指在主从复合句中用作状语的从句。状语从句根据其用途可分为时间状语从句、地点状语从句、原因状语从句、结果状语从句、目的状语从句、条件状语从句、方式状语从句等： He was angry because I was late. 他很生气因为我迟到了。(原因状语从句) He was so angry that he couldn’t speak. 他气得话都说不出来。(结果状语从句) Although he is poor, he’s happy. 虽然穷，但他仍很快乐。(让步状语从句) Put it where you can reach it. 把它放在你可以拿到的地方。(地点状语从句) Speak clearly so that they may understand you. 讲清楚些，以便他们能理解你。(目的状从) 中考英语语法复习：主谓语法一致的原则 谓语受主语支配，须和主语在人称和数上保持一致，这叫做主谓一致。主谓一致一般遵循三条原则：语法一致原则，意义一致原则和就近一致原则。 1. 语法一致的原则 （1）以单数名词或代词，动词不定式短语作主语时，谓语动词要用单数;主语为复数时，谓语用复数，例如： He goes to school early every morning. The children are playing outside. To work hard is necessary for a student. （2）由and或both……and连接的并列成分作主语时，谓语动词用复数。例如：Both he and I are right. Mr Black and Mrs Black have a son called Tom. 但并列主语如果指的是同一人，同一事物或同一概念，谓语动词用单数。例如： His teacher and friend is a beautiful girl. The poet and writer has come. （3）由and连接的并列单数主语之前如果分别由each, every修饰时，其谓语动词要用单数形式。例如： In our country every boy and every girl has the right to receive education. Each man and each woman is asked to help. （4）主语是单数时，尽管后面跟有but ,except, besides, with 等介词短语，谓语动词仍用单数。例如： The teacher with his students is going to visit the museum. Nobody but two boys was late for class. Bread and butter is a daily food in the west. （5）一些只有复数形式的名词，如people, police, cattle, clothes等作主语时，谓语动词要用复数。例如： A lot of people are dancing outside.
状语从句的时态特点
涉及状语从句的几种特定时态 1. “主将从现”原则 即若主句为一般将来时，时间和条件状语从句通常要用一般现在时表示将来，而不能直接使用将来时态。如： I’ll give her the telex when she comes. 她来时把电传交给她。 I’ll return the book as soon as I have read it. 这书一看完我就送还。 He’ll have four years at university after he leaves school. 他中学毕业后要上四年大学。 2. since与完成时 since 引导时间状语从句时，其主句通常要用现在完成时，有时也用现在完成进行时。如： She has had another baby since I saw her last. 从上次我见到她以来，她又生了一个孩子。 He has grown an inch since I saw him. 我上次见到他以后他已长高了一英寸。 注：当主句为“It + be + 一段时间”时，则通常用一般现在时代替现在完成时。如：It’s more than three years now since I saw her last. 我们已有三年多没见面了。 3. 特定句式的时态 由no sooner. . . than, hardly [scarcely]…when引出的时间状语从句，其主句通常用过去完成时，从句通常用一般过去时。如： Hardly had he arrived when she started complaining. 他刚到她就抱怨起来。 No sooner had he gone to sleep than the telephone rang. 他刚睡着电话铃就响了。 We had no sooner set out than a thunderstorm broke. 我们刚出发就下起一阵雷暴。 No sooner had she agreed to marry him than she started to have terrible doubts. 她 刚同意嫁给他她就开始产生可怕的疑虑。
When引导的定语从句与时间状语从句的区分
一、从句是如何出题的 1. 时态 2. 考连接词 3. 考语言顺序 二、学好从句的两个基本条件 1. 时态 2. 从句的三个必须:①必须是句子；②必须有连接词；③必须是陈述句 三、状语从句、宾语从句、定语从句重点 1.如何判断何种从句 2. 从句的时态 3. 从句的连接词与扩展 4. 经典单选、从句与选词、长句子分析 四、如何判断三种从句 1. 状语从句无先行词 2. 宾语(表语)从句无先行词有动词或词组 3. 定语从句先行词多为名词或代词 一、When引导的定语从句与时间状语从句的区分 1. when的译法不同。在时间状语中，when 翻译成“当……的时候”I want to be a teacher when I grow up. 当我长大的时候，我要做一名老师。在定语从句中，when不翻译。I won't forget the day when he says he loves me. 我不会忘记他说爱我的那一天。 2. 在时间状语中，when从句前面或后面是句子；定语从句中，when从句不能位于句首，且通常when前为表示时间的名词day、year等。 3. when在从句的作用不同。在时间状语从句中，when是连词，只起连接主句和从句的作用，不做从句的任何成分。不过when引导的时间状语从句修饰主句的谓语，做主句的时间状语。 在定语从句中，when是关系副词，在从句中代替先行词做从句的时间状语，修饰从句的谓语。 例1 I will always remember the days when I lived with my grandparents in the country. 例2 I always remember the days in the country when I see the photo of my grandparents. 点评：例1意为“我会永远记得跟我祖父母一起住在乡下的那些日子”，其中when 引导的是一个定语从句, 修饰the days, when在从句中作时间状语。例2意为“当我看到祖父母的照片时，总是会想起在
英语语法之时间状语从句
时间状语从句常由以下连接词引导：when（当……时），as（一边……一边；当…时），while（在……期间），after（在……之后），before（在……之前），as soon as（一……就），since（自从），till(until)（直到……，直到……才），whenever（任何时候），the moment（一……就），no sooner than（一……就），hardly…when… （一……就）等。由以上连接词（或词组）连接的主从复合句中，主句和从句的动作，有的是同时发生，有的是先后发生。因此，要特别注意根据连接词所代表的时间不同，主句和从句的谓语要使用相应的时态。这是掌握时间状语从句的关键。 1. when 和whenever 引导的从句：从句的动作和主句的动作可以同时发生，也可以先于主句的动作发生。例如： When we reached home, it was already dark. 我们到家的时候天已经黑了。 When my cousin came yesterday, I was playing volleyball. 昨天我表哥来时，我正在打排球。 When it rains, I go to school by bus.下雨的时候，我坐车去学校。 I shall tell her the good news when she comes. 她来时，我将告诉她这个好消息。（主从句都表示将来发生的动作，但要注意从句中要用一般现在时，表示将来。） Come to see us whenever you can.你什么时候有空，就过来看看我们。 2. while 和as 引导的从句：while表示“当…过程中”，强调某一段时间主句和从句的动作在同时发生。as表示“当…时”或 “一边…一边”，主句和从句的动作同时发生。例如： Work while you work; play while you play. 该工作的时候就工作，该玩的时候就玩。 While he is reading, he always makes notes. 他经常一面看书，一面做笔记。 She sings as she goes along.她边走边唱。 You will grow wiser as you grow older. 随着年龄的增长，你会更加聪明起来。 3. before 和after 引导的从句：前者一般表示主句的动作发生在从句动作之前。后者表示主句的动作发生在从句动作之后。 例如： I didn’t know any English before I came here. 我来这儿之前，一点英语都不懂。 I had written my report before my mother came back.
状语从句的时态特点
1. “主将从现”原则 即若主句为一般将来时，时间和条件状语从句通常要用一般现在时表示将来，而不能直接使用将来时态。如： I’ll give her the telex when she comes. 她来时把电传交给她。 I’ll return the book as soon as I have read it. 这书一看完我就送还。 He’ll have four years at university after he leaves school. 他中学毕业后要上四年大学。 2. since与完成时 since 引导时间状语从句时，其主句通常要用现在完成时，有时也用现在完成进行时。如： She has had another baby since I saw her last. 从上次我见到她以来，她又生了一个孩子。 He has grown an inch since I saw him. 我上次见到他以后他已长高了一英寸。 注：当主句为“It + be + 一段时间”时，则通常用一般现在时代替现在完成时。如：It’s more than three years now since I sa w her last. 我们已有三年多没见面了。 3. 特定句式的时态 由no sooner. . . than, hardly [scarcely]…when引出的时间状语从句，其主句通常用过去完成时，从句通常用一般过去时。如： Hardly had he arrived when she started complaining. 他刚到她就抱怨起来。 No sooner had he gone to sleep than the telephone rang. 他刚睡着电话铃就响了。 We had no sooner set out than a thunderstorm broke. 我们刚出发就下起一阵雷暴。 No sooner had she agreed to marry him than she started to have terrible dou bts. 她刚同意嫁给他她就开始产生可怕的疑虑。

时间状语从句用法
要注意主句和从句的时态大多都要保持一致。） 1.由when, while, ,just ,just as, as，after, before, since, until, as soon as,引导的时间状语从句。例如： When you think you know nothing, then you begin to know something. 当你以为自己一无所知的时候，你就是在开始知道一些事物了。 When truth is buried under the ground ，it grows, it chokes, it gathers such an explosive force that on the day it bursts out , it blows up everything with it. 当真理被埋在地下的时候，它在生长，它感到压抑，它蓄存着这么一种爆炸性力量，一旦冒出，它就会炸破一切！ Strike while the iron is hot. 趁热打铁。 You can feel the air moving as your hand pushes through it. 当你的手在空气中挥动的时候，你就能感觉到空气在流动。 Our headmaster laughed as she spoke. 我们的校长边谈边笑。 主要时态：主现从不现；主过从四过；主将从现。 when, while和as的区别 when引导的从句的谓语动词可以是延续性的动词，又可以是瞬时动词；动作既可以 和主句的动作同时发生，又可以在主句的动作前后发生。并且when有时表示“就在 那时”。 例如： When she came in, I stopped eating.她进来时，我停止吃饭。(瞬时动词) When I lived in the countryside, I used to carry some water for him. 当我住在农村时，我常常为他担水。（延续性的动词） We were about to leave when he came in.我们就要离开，就在那时他进来了。While引导的从句的谓语动作必须是延续性的，并强调主句和从句的动作同时发生 （或者相对应）。并且while有时还可以表示对比。 例如： While my wife was reading the newspaper, I was watching TV. (was reading是延续性的动词，was reading和was watching同时发生) 。 I like playing football while you like playing basketball. 我喜欢踢足球，而你喜欢打篮球。（对比） As表示“一边……一边”，as引导的动作是延续性的动作，一般用于主句和从句动 作同时发生；as也可以强调“一先一后。例如： We always sing as we walk.我们总是边走边唱。（as表示“一边……一边”）As we were going out, it began to snow.当我们出门时，开始下雪了。 （as强调句中两个动作紧接着先后发生，而不强调开始下雪的特定时间）

状语从句的时态特点一般情况下
状语从句的时态特点一般情况下，时间和条件状语从句的谓语动词一般用“一般现在时”表示“一般将来时”，用“现在完成时”表示“将来完成时”。例如： I will call you as soon as I arrive in Beijing. 我一到北京就给你打电话。（这是由as soon as引导的时间状语从句，从句中的谓语动词arrive是一般现在时，表示一般将来时，决不可用will arrive） As soon as I have finished this work, I will go home. 我一完成此工作，就回家。（从句中的谓语动词用现在完成时have finished，表示将来完成时,决不可用will have finished）If he comes back, please let me know.如果他回来了，请通知我。（从句中的谓语动词用comes back,表示一般将来时，决不可用will come back） 状语从句讲解和练习 状语修饰动词、形容词、副词或整个句子。通常由副词、介词短语、动词不定式、分词和从句等担当。例如： 1.
