英语语法最佳学习方法：从阅读中领悟
英语语法最佳学习方法：从阅读中领悟
怎样才能学好语法？读语法书有用吗？
其实，语法是从阅读学来的。
语法书当然有用，但它和字典一样，只是从旁辅助的工具。只看语法书却从不阅读，一定会走火入魔，其下场与死背生词相同。
我们学生的作文甚至论文有一个通病，那就是用字太深，但却很少用得对，于是整篇文章充斥着无数用生僻词汇串成的怪异句式。甚至一篇洋洋洒洒数万字的论文，往往只有数十句通顺的话，这便是学习时只重背诵生词，忽视语法的产物了。
其实，学习语法与学习生词相似，都要in context地学。死记硬背单词没有用处，因为你不懂单词的用法，也不清楚其应用的场合以及语气。同样地，像背诵公式般死记什么名词关系从句，什么分词修饰语，即便词序和结构都懂了，写作时真的用得着吗？用得对吗？例如许多人写出的倒装句，十有八九会出错。并非结构出错，而是运用不当。
既然语法规则不能死记硬背，那么语法该怎么学？
从阅读中领悟语法，再以语法书巩固领悟而来的知识。
举个简单的例子。冠词the看似简单，其实用法深奥多变。一本详尽的语法书往往会记录数十条运用the的规则，以及无数的例外情况，而且例外中仍有例外。比如：“根据冠词法规第五条第三小节，这里应用the而非a，但由于前面出现了某字，符合了例外情况三，所以这里用the...”。看看吧，这么多规则以及例外，如果死记的话，记得住这么多吗？即便记下了，写作的时候也未必用得出。
学好语法，语感比规则重要。
养成阅读英文的习惯。仍以the为例。每次读书时总会遇到the字数十次，而每次都会见到不同的情况，不同的句式。读的多了，加上多留意词语之间的关系，便自然能领悟出the字微妙的用法，写作时也能够少犯错。
阅读时遇到困惑，再去翻阅语法书。这时，语法书上的繁杂规则就正好派上用场了。因为你知道自己要找什么，也知道这些语法规则怎样应用于实际的句子。
英语语法大攻克--现在完成时的讲解

google搜索从入门到精通4.0
Google搜索从入门到精通 v4.0 （一） 1、前言 我是在2000年上半年知道GOOGLE的。在这之前，我搜索英文信息通常用AltaVista，而搜索中文信息则常用 Sina。但自使用了GOOGLE之后，它便成为我的Favorite Searchengine了。这也得感谢新浪网友曹溪，因为当初正是因为他的大力推介，才使我识得了GOOGLE。 记得1996年夏季的时候，当我第一次接触Internet，便被扑面而来的魔力征服了。那种天涯咫尺的感觉，真是妙不可言。在经历了疯狂的WWW冲浪和如痴如醉的BBS沉迷之后，我意识到Internet对我影响至深的还是在于学习方式的变迁。 如何来描述这种变迁呢？以前的学习，一般需要预先在肚子里存储下足够的知识，必要时，就从海量的信息中提取所需的部分。这种学习方式造就了很多“才高八斗，学富五车”的大才子。但是，到了信息领域大大超出“四书五经”的新时期，预先无目的的吞下海量信息的学习方式就有些不合时宜了。比方说，我们到了大型的图书城，往往有一种不知所措的感觉。旧有的学习方式需要变更以适应这个信息爆炸的年代。目的明确的去学习，即先知道要学什么，然后有目的的去寻找答案，这种方式看上去更加有效率。我不妨把这称为“即学式”，相应的，旧有的称为“预学式”。不过，“即学式”的实施是有前提的。首先，要求学习者拥有一个包罗万象的信息库，以供随时抽取各种目的信息；其次，是需要一个强劲的信息检索工具，以便高效率的从信息库中提取信息。很明显，Internet可以充当那个海量的信息库，而搜索引擎，则正是寻找光明之火的绝好工具。 “公欲善其事，必先利其器”。Internet只有一个，而搜索引擎则有N多个。有搜索高手说，所谓搜索，就是“在正确的地方使用正确的工具和正确的方法寻找正确的内容”。但是，对于普通人而言，掌握诸多搜索引擎的可能性似乎不大。用一两个相对强劲的具代表性的工具达到绝大多数搜索目的更为人们所迫切希望。不同的时期，涌现出不同的强者。就目前而言，我们非常幸运的有了： *****GOOGLE***** 2、摘要 本文简要的介绍了GOOGLE的历史和特点，GOOGLE的基本搜索语法和高级搜索语法，GOOGLE的特

高中英语---特殊句式全面讲解及练习
高中英语语法讲义第二讲——特殊句式 倒装句 通常句式为自然语序“主语+谓语”，有时为了强调句子的某一部分，或者出于词汇用法、语法结构或修辞上的需要，将这种比较固定的语序加以颠倒，就形成了倒装。分为完全倒装，部分倒装和形式倒装。 一.完全倒装：谓语动词完全置于主语之前，主语为名词不为代词，谓语不用进行时。 1.一些表示地点、时间或方位等的副词或介词短语。如：here, there, now, then, up, down ,in, out, away, off, in the room, on the wall等置于句首。 Down came the rain and up went the umbrella. Then followed three days of heavy rain. Out rushed the children laughing loudly. Away flew the plane. 2.such 位于句首。 Such was Albert Einstein, a simple man and the 20th century’s greatest sc ientist. 注：此句型中的such多被认为是表语，所以such后的be动词应与其后真正的主语保持一致。 Such are the facts; no one can deny them. 二．部分倒装：只把谓语的一部分（助动词，情态动词或be动词）置于主语之前 1.so+ be 动词/ 助动词/ 情态动词+主语，意为“...也是如此”。 They love making lots of friends; so do I. 2.neither/nor+ be动词/助动词/情态动词+主语，意为“...也不这样”。 Lily can’t ride a bicycle; neither/nor can Lucy. 3.否定词never, seldom, nor, not, little, hardly, scarcely等或表示否定意义的介词短语at no time, under/in no circumstances, in no case, by no means, on no condition 等置于句首时。 Not a single mistake did he make. =He d idn’t make a single mistake. 4.only 修饰副词、介词短语或状语从句，且放在句首时。 Only then did I begin to understand him. Only in this way can we solve the problem. Only after the war did he learn the sad news. 5.so...that...和such...that...句式中，so或such及其所修饰的部分置于句首时，主句用部分倒装。 So clearly does he speak English that he can always make himself understood Such progress did he make that he won much respect.

高中英语语法之特殊句式的结构
特殊句式的结构 1.It 结构一、强调句 强调句的基本句型是“It is/was＋被强调的部分＋that/who＋其他部分”。被强调的部分可以是主语、宾语和状语等。强调句型的使用特点主要有以下几个方面： (1)被强调的是状语或状语从句时，要用that引导从句，而不能用which，而且通常不能省略。 (2)被强调的是人时，引导词可用who，也可用that。 Was it you that/who let out the secret to her? 是你把这个秘密泄露给她的吗？ (3)被强调的不管是单数还是复数名词，主句的be动词都用单数is或was。 It was Marie Curie and her husband who discovered radium. 是居里夫人和她的丈夫发现了镭。 It is the PLA men who/that are safeguarding our country day and night. 是解放军战士日夜保卫着我们的祖国。 (4)对not...until时间状语从句进行强调时，其句型是： It is/was not until...that从句，即not和until在强调句中总是紧挨着的。注意习惯上不用not till，而且从句不能用when引导。 It was not until the last operation was finished that Bethune left the battle hospital. (5)强调句的疑问形式： When was it that he made up his mind to take this course? 他是什么时候决定选修这一门课程的？ Why is it that he doesn’t like th e book? 他为什么不喜欢这本书？ Was it in 1939 that the Second World War broke out? (6)强调句型与It is/was＋时间＋when从句： 在上述句型中it指时间，when引导的是时间状语从句。 注意两种句型“时间”表达方式的不同。 It was at midnight that I got back home yesterday. 昨天晚上我半夜才回到家。 It was midnight when I got here yesterday. 昨天当我到达这儿时，已是半夜了 2.but 的用法 a.anything but…一点儿也不 She was anything but mad. b.nothing but…仅仅，只 She heard nothing but the wind. c. but for….除非，要不是 But for your help, I wouldn’t have succeed. d. can’t help but do (can’t help doing…) 禁不住…

英语语法、句式、简单句子结构(透彻分析)
LESSON ONE 句子的三种模式 导言本课的重点是掌握英语的三种基本句型，注意词性和词序，以及定语的位置,同时注意中英文表达上的相同和不相同的地方。三种基本句型虽然简单，但至关重要。掌握好它们，在今后的学习中有一通百通之效。 ▲主+系动词+表 注：*注意该结构中的名词，它们能被定语修饰。 1 这个人是一个老师。The man is a teacher. 主语系表语主语系表语（名词） 2 他（是）很忙。He is busy. 主语系表语主语系表语（形容词） ▲注意中文中的系动词经常被省略,而英文中绝不能省。 3 她（是）在教室里。She is in the classroom.
主语系表语主语系表语（介词短语） ▲定语只修饰名词，不破坏句子的基本结构。通常由形容词和介词短语充当，形容词放在所修饰的名词之前，而介词短语放在所修饰的名词之后，请注意英语与汉语词序的不同。看懂中文的定语是翻译好定语的关键。 介词短语 ---英国法学家波洛克 介词短语 Happiness is a station -----------Pollock, British jurist 形容词介词短语 5 形容词介词短语 man is a teacher 介词短语形容词
6.教室里。 形容词介词短语 The teacher is handsome. My book is 表语（介词短语）定语（介词短语） She is 介词短语即可以做表语也可以做定语，虽然它们词性相同，但由于词序不同，它们所起到的作用也不同，当在is的后面是表语,跟在名词的后面它就起到定语的作用。 课堂练习 1 1是
英语语法完成时篇
完成时篇（一）——现在完成时 [提问] 请问在句子“Working in London has been the best decision I have made so far. （Experiencing English Integrated Book1 Page71）”中，为什么时间状语是完成时的情况下，主句仍然可以使用现在完成时呢？ 答：完成时态通常表示已完成或已经开始从事的动作，它可以分为现在完成时、过去完成时、将来完成时以及完成进行时。根据定义我们可以了解到，除了表示到现在为止动作已经完成或已经开始以外，还有多种情况可以用现在完成时来表达。 一、动作从过去某个时间开始发生，延续到现在，并且说话前已经完成。 例如：The mission has been carried out well.任务已经很好地完成了。 Those girls have eaten two big cakes.女孩们已经吃了两个蛋糕了。 二、某个动作或状态发生在过去，持续并影响现在，有可能会继续保持下去。 例如：My brother has been abroad for several years.我哥哥已经出国好几年了。 It has rained all morning.雨下了一个早晨。 Up to now, parents have accepted the pop music youths prefer to.现在，家长们 已经接受了年轻人喜欢的流行音乐。 I have known him since the summer in 2001.自2001年的那个夏天，我就认识他了。 三、动作发生在现在之前的某个时间，可能是多次动作的集合，也表示习惯性的动作或 状态。 例如：Xiao Qin has come over here three times in the daytime.白天小覃已经来过三次了。 Which countries have you traveled recently?最近你都去过那些国家？ How many papers have you read today? 你今天看了几篇论文？ 四、动作过去曾发生过一次或多次，也可能是一种经历。 例如：Students are very pride that the president has once visited their school. 学生们为总统曾访问过他们学校而骄傲。 Accidents like this have happened more than 20 times these years.这几年此类事故发生不下20起。 在现在完成时态的句子中，常伴随的时间状语有：already，yet，ever，never，just，before，lately，recently，till/until，always，now，since，today; in past years，all morning，all one’s life，up to now，these days，this week/month/year，for a long time。 现在完成时中有几点语法点要注意的： 1）for引出的时间状语只能修饰表示延续性动作的动词。不能用来修饰表示瞬间、短 暂动作或位置转移的动词。如John has come to China for three years，此句错误，come这个动作是短暂性动词，不可能持续发生，因此可改为John has been in China for three years，约翰已经爱中国生活了3年。短暂性动词有appear, begin，borrow，buy，come，close，die，fall，find，finish，join，kill，leave，lend，lose，see，start，stop。 2）在表示时间或条件的状语从句可以用现在完成时表示将来完成的动作。 例如：He will not quit my job until his parents have permitted.父母允许后他才会辞职。 I will arrive at 6 o’clock if the car h as been prepared then.如果到时车准备好了，我能在6 点到达。 3）It is the first/second time that…这个结构中，that从句要用现在完成时。 例如：It is the first time that I have heard of his deeds.这是我第一次听说他的事迹。
