2011届高考英语一轮复习讲解：it的用法
2011届高考英语一轮复习讲解：it的用法【知识要点】 It的用法 （一）作人称代词 1、it代替前面（或后面）的单数名词或分句等所表示的事物。 e.g. You cannot eat your cake but have it.（it代替前面的cake） Although we cannot see it, there is air all around us. （it代替后面的air） They say he has left town, but I don’t believe it.（it代替前面They…town分句中的情况） 2、代替有生命但不能或不必分阴阳性的东西（包括婴儿）。 e.g. Yesterday we saw a big tree. It was fully twenty metres high. （it代替前面的tree） The baby cried because it was hungry. （it代替前面的baby） 3、在某些习惯说法中，可以代替人。 e.g. ---- Someone is knocking at the door, Peter. ---- Who is it? ---- It’s me. ---- Who are singing? ---- It is the children. ---- The light is still on in the lab. It must be the third-year students doing the experiment. 4、it与one的区别：这两个词都可以代表前面说过的名词，但it用于同名同物的场合；one则用于同名异物的场合。 e.g. ---- Do you still have the bicycle? ---- No, I have sold it. ---- Is this knife yours? ---- No. It is Xiao Zhang’s. Mine is the one on the desk. 5、it与that的区别：两词都可代替某一特定名词，但that指同一类，并非同一个。 e.g. The climate of South China is mild（温和的）; I like it very much.（it指the climate of South China） The climate of South China is much better than that of Japan.（that指the climate）（二）作无人称代词 it作无人称代词时，除了句中找不到它所代表的词语外，另一个特点是它后面的内容都是表示天气、时间、距离、度量衡及情况等。 It is fine (rainy, windy, etc.). It is noon. It is a half hour’s walk to the f actory. It is eighteen square metres in area. What does it matter? （三）作强调词，构成强调结构
英语it的用法及练习
it的用法及练习 一、概述 在英语中，it的使用相当广泛，它既可用作代词，如人称代词（personal it）、指示代词（demonstrative it）及非人称代词（impersonal it）, 也可用作引导词（anticipatory it）和强调结构中的强调词（emphatic it） Someone is ringing the doorbell. Go and see who it is.有人在按门铃。去看看是谁。（人称代词）What’s this?这是什么？ It’s a book.这是一本书。（指示代词） What a long way it is from Beijing to London! 从北京到伦敦真远。（非人称代词） It's best to plant trees in spring because it's warmer.春天是植树的最佳时节，因为天气更暖和。（作引导词） It was I who met him in the park last week. 是我上星期在公园遇到他的。（强调结构中的强调词） 二、it作代词 1、用作人称代词（personal it） 代替前文提到过的事物，it作真实主语或宾语。 The frog is not a warm-blooded animal. It is a cold-blooded one.青蛙不是温血动物，它是冷血动物。My pen is missing. I can't find it anywhere. 我的笔丢了，我哪儿也找不到它了。 I won't be back tonight. Please tell my wife about it .我今晚不回来了，请你向我妻子说一声。 I was disappointed with the film. I had expected it to be much better. 我对这部电影很失望，我曾盼望它更好。 Tom's mother kept telling him that he should work harder, but it didn't help.汤姆的妈妈不停地告诉他要努力，但这没起作用。 2、用作指示代词（demonstrative it） 相当于this或that，it有时不特指某件东西，而代表前面已提到的或将会发生的某件事情。 -Who is knocking at the door? —谁在敲门？

Her dream has 2）我的书在书桌上。）3My books are on the desk. 这食物似乎不错seems ）4The food to be nice. 1 / 13 本句型的特点是连系动词+表语二者缺一不可。例如呜敨琠慥档牥愠杮祲和We in the classroom. She sixteen.都不成其为一个句子。汉语中形容词、介词短语、数词都可以用作谓语，但是英语中它们不能单独作谓语，它们前面必须加上一个系动词才能构成谓语。 Exercises:Put the following sentences into English. key 1 1. 李甜甜是个聪明的女孩。 2. 张飞在三年级六班。 3. 冬季白天短,夜晚长。 4. 早起有益于身体健康。 5. 这些玫瑰花闻起来很香。 b.主语+不及物动词 (S+V) 在此句型中，谓语动词是不及物动词，其后没有宾语。因为此句型中的动词表达的意思已经很明确，所以不需要跟宾语。有时为了表示动作发生的频率、程度、原因、结果、目的、场所、时间等，可以带状语修饰动词。如： 1）My head aches. 我头疼。 学生们正在听。2）The students are listening．

2019-2020学年山西大学附中高一上学期期中考试 语文
山大附中2019～2020学年第一学期期中考试 高一年级语文试题 考试时间：120分钟考查内容：综合题 一、文学类文本阅读(15分) 阅读下面的散文，完成1～3题。 秋风桐槐说项羽 梁衡 ①这里属于江苏省宿迁市。我原以为故里者只是一座古朴的草房，或农家小院，不想这项羽故里竟是一座新修的旅游城，而城中真正与项羽有关的旧物也只有两棵树：一棵青桐，一棵古槐。斯人远去，就只有来凭吊这两棵树了。 ②那棵青桐，树上专门挂了牌，名“项里桐”。据说，项羽出生后，家人将他的胞衣(胎盘)埋于此树下，这桐树就特别茂盛，青枝绿叶，直冲云天。在中国神话中梧桐是凤凰的栖身之地，有桐有凤的人家贵不可言，项羽在此树下出生盖有天意。梧桐之东不远处，有一棵巨大的中国槐，说是项羽手植。两千年的风雨，手植槐修成了黄河槐；黄河槐又炼成了雷公槐。这摄取了天地之精、大河之灵的古槐，日修月炼，水淹不没，沙淤不死，雷劈不倒，壮哉项羽！ ③项羽的家乡在苏北平原，两千年来战火无数，文物留存极少，而其故里一直未被忘记，直到现在这个旅游城。城内遍置各种与项羽有关的游乐设施，其中有一种可在架子上翻转的木牌，正面是项羽、虞姬等各种画像，翻过来就是一条条因项羽而生的成语。如：破釜沉舟、取而代之、一决雌雄、所向披靡、拔山扛鼎、分我杯羹……现在我们常用到的成语总共也就一千多条，项羽一人就占百条。要知道他才活了三十一岁，政治、军事生涯也只有五年。后人多欣赏他的武功，倒忽略了他的文化贡献。 ④项羽是个失败的英雄，失败缘于他人性的弱点。刚烈坚强又优柔寡断，欲雄霸天下又留恋家乡；他少不读书，临终之时却作“力拔山兮气盖世”，感天动地、流传千古；他杀人如麻，却爱得缠绵，在身陷重围、生死存亡之际还与虞姬弹剑而歌。他身上有巨大的悲剧之美，因此他是艺术境界中的人物，是艺术创作的好原型。 ⑤项羽是民间筛选出来的体现了平民价值观和生活旨趣的人物，人们喜欢他的勇敢刚烈、纯朴真实，就如喜欢关羽的忠义一样。历史上的“两羽”一勇一忠，成了中国人的偶像，是与岳飞的精忠报国、文天祥的青史丹心并存的两个价值体系。一是做人，一是爱国。他是一面历史的多棱镜，能折射不同的光谱，满足人们多方位的思考。后人常以对他的褒贬，来抒发自己的感慨。杜牧抱怨他脸皮太薄：“胜败兵家事不期，包羞忍耻是男儿。”李清照却推崇他的刚烈：“生当作人杰，死亦为鬼雄。”毛泽东则借他来诠释政治：“宜将剩勇追穷寇，不可沽名学霸王。”而就在这个园子里，在秋风梧桐与黄河古槐的树荫下，我看见几个姑娘对着虞姬的塑像正若有所思…… ⑥这个旅游城的设计是以游乐为主，所以强调互动，游人可上去乘车骑马，可与雕像拥抱照相，可出入项羽的卧房、大帐。但有两个地方不能去，那就是青桐树下和古槐树旁……秋风乍起，红色的方舟上托着两棵苍翠的古树。 ⑦站在项羽故里，我们先要感谢司马迁，还要感谢这两棵青桐和古槐。幸亏有这青桐、古槐为这故里存了一脉魂，为我们存了一条汉文化的根。我以为要记录历史：一是文字，如《史记》；二是文物，如长城、金字塔；三是古树。因为时间比人的寿命更长，又与人类长相厮守的活着的生命就只有树木了。 ⑧秋风梧桐，黄河古槐，塑造了一个触手可摸的项羽。

编号17 山西大学附中高二年级排序不等式
山西大学附中高二年级（下）数学导学设计 编号17 排序不等式 【学习目标】了解排序不等式的基本形式，会运用排序不等式分析解决一些简单问题; 【学习重点】排序不等式的应用 【学习难点】排序不等式的证明 【学习过程】 一、导学： 1. 一般形式的柯西不等式：设n 为大于1的自然数，,i i a b R ∈(=i 1,2,…,n )， 则： .当且仅当 时, 等号成立. (若0=i a 时，约定0=i b ，=i 1,2,…,n ). 变式10. 设,0(1,2, ,),i i a R b i n ∈>= 则：∑∑∑≥=i i n i i i b a b a 212 )( . 当且仅当 时, 等号成立. 变式20 . 设0(1,2, ,),i i a b i n ?>= 则：∑∑∑≥=i i i n i i i b a a b a 2 1 )(. 当且仅当n b b b === 21时,等号成立. 2. 探究 如图， 设AOB α∠=，自点O 沿OA 边依次取n 个点 12,,,n A A A ，OB 边依次取取n 个点12,,,n B B B ，在OA 边取某个点i A 与OB 边某个点j B 连接，得到i j AOB ?，这样一一搭配，一共可得到n 个三角形。显然，不同的搭配方法，得到的i j AOB ?不同，问：OA 边上的点与OB 边上的点 如何搭配，才能使n 个三角形的面积和最大（或最小）？？？ 设,(,1,2,,)i i j j OA a OB b i j n ===，由已知条件，得 123123,n n a a a a b b b b <<<<<<<< 因为i j AOB ?的面积是 ，而 是常数，于是，上面的几何问题就可以归结为 代数问题：1212,, ,,,,,n n c c c b b b 设是数组的任何一个排列 则1122n n S a c a c a c =+++何时 取最大（或最小）值？ 我们把1122n n S a c a c a c =+++叫做数组12(,,,)n a a a 与12(,,,)n b b b 的乱序和. 其中, 1121321n n n n S a b a b a b a b --=++++称为 序和. 2112233n n S a b a b a b a b =+++ +称为 序和. 这样的三个和大小关系如何? ◆探究新知 1.检验操作: 填表: 2.一般性证明:
