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

九年级it用法及练习
It的用法总结 在英语中,it有许多不同的用法,它既可以用作代词(如人称代词、非人称代词)，也可以用作引导词（作形式主语或形式宾语），还可以用来构成强调句型。 1.it用作代词 (1) 用作人称代词在句子中作主语或宾语；指前面已经提到过的事物、动物或人，且it指特定的事物；如果指前文中提到的事物中的任何一个，用one。one可以与any, each, every, not等连用，但one不可代替不可数名词。 —Where's your car? —It's in the garage. 你的汽车在哪儿呢？在车库里。(指代物品your car) Did you hit it? 你打中了吗？(指代事件) The baby cried when it was hungry.这婴儿饿时就哭。（指代婴儿，尤指性别不详或无所谓时）—Who is that? —It's me. 是谁？我。(指一定情景中所确定的人或事物，此时相当于指示代词，代指this和that,有时也指人) —What's this? —It's a box. 这是什么？一只箱子。 (2) 作非人称代词表示天气、日期、时间、温度、距离、价值、路程、度量、自然现象与环境等。也可模糊地指一般情形或上文的部分或整个意思。译成汉语时，it通常不一定译出来。 It's a long time since they left. 他们走后很久了。 It's two miles to the beach.离海滨有两英里远。 That's just it—I can't work when you're making so much noise.原因就在这里——你弄出这么大的声音，我工作不了。 另外，需要注意两点： （1）“It's time…”后面可以接不定式和介词短语表示“是做……的时候了”。如： It's time for supper. It's time to have supper. (2) “It's time…”后面还可以接一个从句，但是从句中的谓语动词一定要用过去式即虚拟语气，如： It's time we had lunch.是我们吃饭的时候了。 It's time we started.是我们该出发的时候了。 2.it用作引导词 (1) 作形式主语由动词不定式、动词-ing短语或名词性从句担任主语的句子，常用it来作形式主语，而把真正的主语放在句子的后面。 It's not easy for us to learn English well. [句型为: It +be+形容词+（for sb.）to do sth.] It's foolish of you to say that to her. [句型为: It +be+形容词+（of sb.）+to do sth.] It's no use/good/help…sleeping too much. (句型为: It +be+名词+doing) It's important that we be there on time.（句型为: It +be +形容词+that从句） It's high time that Tom went to school. (句型为: It +be +time +that从句，从句中的动词用过去时) It was the second time that he had telephoned me that day. [句型为: It +be+ the first(second, third)time +that从句]（that从句中动词用完成时） +that过去分词: It +be+句型为It was arranged that they should leave the following winter. ( 从句)
it用法的五类考点
it的五类考点和用法 一、考查 it 用作形式主语的用法 当不定式、动名词、从句等用作主语时，为避免头重脚轻，通常在句首使用形式主语it，而把真正的主语放在句子末尾。如： It’s no good sitting up too late. 熬夜没有好处。 It doesn’t matter what he says. 他说什么没关系。 【特别提醒】注意it用作形式主语的三类特殊句式： 1.用作动词look, seem, appear, happen, occur, follow等的主语(后接that从句或as if从句)。如： It seems that he knows everything. 他好像什么都知道。 " It (so) happened that I had no money with me. 碰巧我没带钱。 2.当系表结构后接有if 或when引出的状语从句时，通常在系表结构前使用形式主语表示说话人对某情况的看法。如： It was a great surprise to me when he did a thing like that. 他这样做使我很吃惊。 It would be a tragedy if anything went wrong. 如果出了什么事就是一个悲剧。 3.用于if it were not for… / if it hadn’t been for…(若不是因为)。如： If it hadn’t been for the freezing wind they could have reached the injured man in time. 要不是有刺骨的寒风，他们就及时赶到伤员身边了。 二、考查 it 用作形式宾语的用法 当不定式、动名词、从句等用作宾语且其后跟有宾语补足语时，就应在宾语补足语前使用形式宾语，而将真正的宾语移至句末： ~ We found it difficult to persuade her. 我们发现很难说服她。 He makes it a rule to get up before dawn. 他习惯于天亮前起床。 I think it very strange that he goes out walking almost every night. 我认为他几乎每晚都出去散步是很奇怪的。 【特别提醒】注意it用作形式宾语的三类特殊句式： 1. 动词+it+if / when从句 当enjoy, like, dislike, love, hate, prefer, appreciate等动词后需要接一个if或when引导的从句时，此时必须要先在动词后接it作形式宾语。如： She won’t like it if you arrive late. 她不喜欢你迟到。 He hates it when people use his bike. 他讨厌别人用他的自行车。 > I’d prefer it if I didn’t have to do so much work. 要是我不必做那么多工作，那就太好了。 I would appreciate it very much if you would help me with it. 如果你能帮助我做这事，我会十分感激。 2. 动词+介词+it+that从句能用于此句型的主要有三个动词，即depend on, answer for, see to。如： You may depend on it that he will turn up in time. 你可以相信他会及时赶到的。 I can’t answer for it that the boy is honest. 我不能保证这个男孩是诚实的。 I’ll see to it that all these letters will be sent to the post before twelve. 我将注意让所有的信件在12点以前送到邮局。 三、考查 it 在强调句中的用法 — 强调句的基本结构是：It+be+被强调部分+that(who)+其他部分。 如： It was yesterday that he got married. 他是昨天结婚的。 It was a computer that he bought last week. 他上个星期买的是一台电脑。 【特别提醒】对于强调句的复习要特别注意两种情形： 当强调句有插入语或复杂修饰语时： It was lack of money, not of effort, that defeated their plan. 他们的计划受挫，原因是缺少钱而不是没有尽力。 It was more in sorrow than in anger that he criticized his former colleague. 他批评以前的同事，并非出于气愤而是为他惋惜。 2.当强调为特殊疑问句时： ！ Who was it that won the World Cup in 1982 谁赢得了1982年的世界杯 How long ago is it that you last saw her 你上一次看见她是多久以前的事 四、考查 it 与 one 的区别 两者均可代替前面提到的事物，区别是：it指的是与前面已提到的事物为同一物，此时的it等于“the (this, that, my...)+名词”；而one 指的是与前面已提到的事物为同一类物，此时的one 等于“a+名词”。比较 I have a dictionary but I’ve lent it to Mary. 我有一本词典，但把它借给玛丽了。 I haven’t a dictionary; can you lend me one 我没有词典，你能借我一本吗 五、考查 it 在习语中的用法 包括it的习语很多，比如make it就是其中很重要的一例。如： You can make it if you hurry. 如果你赶快还可以及时赶到。 ` You needn’t worry; he will make it. 你不必担心，他会办成的。 含有“It is …”的句型 一、it指代时间时，有如下一些句型： （1）It is time (for sb.) to do sth. It is (high/about) time that sb. should do / did sth.(虚拟语气) 例：① It's time for lunch. ② It's time for us to clean the house. ③ It's time that we should clean the house.
It's time…用法归纳
It's time…用法归纳 It's time…句型是中学英语里使用频率较高的句型，其意为“该是……的时候了”。用法灵活多变，也是大家以掌握的句型。现就其有关句式归纳如下： ⑴ It's time for + n.“该是（干）……的时候了。”例： Boys and girl, It's time for class. 同学们，该上课了。 ⑵ It's time + (for sb.) to do sth. .表示“该是（某人）干……的时候了。”例： It's time for you to clean the classroom. 该是你打扫教室的时候了。 It's time to go to school. 该去上学了。 ⑶ It's time + that clause 时，that可省略，time可由high,about修饰，从句中的谓语动词有两种形式，或者用动词的过去式(be用were)；或者用shoud + 动词原形（should不能省略)。此句型为虚拟语气句型，表示“现在某人该做某事了”。含有该事早该去做而未做，现在去做似乎都为时已晚的意思。例： It's time （that）we went to bed. 我们该去睡觉了。 It's high time that the article were published. 发表这篇文章是适时的。 It's time you should do cleaning. 你该去打扫卫生了。 4) It's + the+序数词+ time+ that clause.也表示某人第几次做某事。例： It is my first time that I've even written letters. 这是我第一次用写信。

it句型(包括强调句等经典句型)(教案)
教学过程 一、复习预习 1、教师出示上节课预留的练习题，根据学生实际情况进行讲解分析； 2、引导学生复习上节内容； 3、并引入本节课程内容。 二、知识讲解 考点/易错点1 it基本用法 ①it用作代词，代替前面提到过的人或事。如： —Is the baby a boy or a girl? —It’s a boy. (it指上文提到的baby) The doctor advised Vera strongly that she should take a holiday, but it didn’t help. (it指上文叙述的事)
注意： it, that, one都可以用来代替前面提到的人或事，但这三个代词之间有不同之处： it用来代替前面提到的可数名词，所指的是事物本身；that用来代替不可数名词，指的是前面提到的名词中的同一类事物；one则用来代替前面出现过的可数名词，并且是指这类事物中的一个。如： I can’t find my pen anywhere. I must have lost it. (it指前面的pen本身) Life today is much better than that in the old days. (that指代前面提到的与life同类的事物) I can’t find my pen. I’m going to buy one. (one指前面的pen这类事物中的一个) ②it可用来指天气、时间、距离、自然环境等。如： It was very cold in Beijing in winter. （it指天气） It was too late and I had to leave for home. （it指时间） What a long way it is from Beijing to London! （it指距离） It was quiet in the school at night. （it指自然环境） ③it可用来指人，特别是不知道对方的性别时。如： Whose baby is it? It’s very lovely. 考点/易错点2 It 用作形式主语 当不定式（短语）、动名词（短语）或从句在某个句子中作主语时，为保持句子结构前后平衡，避免头重脚轻，因此常用it作形式主语置于句首，而将真正的主语放在句尾。此时it 只起先行引导作用，本身无词义。 e.g. It is wrong to tell a lie. (说谎是错误的。) 〔It为to tell a lie的形式主语〕
