高考英语 it的用法教案
it的用法：
⑴it用作人称代词：指代前面已经提到过的动物、事物、小孩或性别/身份不明的人，但应注意：指宠物时常用he/she，指大动物（马、大象等）可以用he/she；指祖国或家乡时，常用she.
注意句子：He failed in the examine，and it worried him. He failed in the examine. It worried him.
He failed in the examine，which worried him.
⑵it用作非人称代词：常常用作句子的主语，可以指时间、距离、价格、长度、重量、日期、星期、月份、季节、气候等。
⑶it用作形式主语或形式宾语：根据句子结构的需要，人们常用it作形式主语或宾语，而把真正的主语或宾语（不定式短语、动词-ing短语或名词性从句）放在句末。注意it作形式主语的常见结构有：
①It+ be + adj/n（for sb）to do sth.
②It +be + adj of sb to do sth.
③It +be + adj /n+ doing sth（一般限于名词fun，good，luck，joy，use，pleasure
或形容词foolish，wonderful，good，nice，interesting，useless，worth等作
表语时，才用it作形式主语，将真正的动名词主语后置）
④It +be + adj./n + that-clause.
⑤It +be+过去分词（如said，proved，known，believed，reported，thought，hoped，
decided，announced, suggested，ordered，demanded，proposed，requested，advised
等）+that-clause.注意如果表语是划线部分的词，从句应该用虚拟语气。
⑥It takes sb some time to do sth.
⑦It seems/looks as if….
⑷it用在强调句型中：
强调句型“It is/was + 被强调部分 + 其他”的用法
①这一句型可以强调除谓语、表语、定语和同位语以外的任何部分；如果被强调的部分是人，可以用who/that，如果被强调的部分是事物，只能用that。如：It was I who/that came here late this morning. It is a book that is on the desk.
②注意该句型不能强调让步状语从句；强调原因状语从句时，只能用because，不能用
since，as等；强调not…until句型的时间状语时，要把not与until放在一起。另外，not until放在句首时句子必须倒装。如：It was although it was snowing that they went out. （×） I was because he had noticed them watching him that he turned away. It was not until yesterday that he finished his homework. Not until yesterday did he finish his homework？
③在这一句型中，不管强调的主语是单数还是复数，系动词只能用is或was（一般情况下，当句子时态表示现在或将来时用is，当句子的时态表示过去时用was）。如：
It is Jim that will go to the park tomorrow. It was Lily that finished her work.
④注意这一句型变否定句、一般疑问句、特殊疑问句和反意疑问句的变法。特殊疑问句
变强调句型时，只强调特殊疑问词，其结构为：特殊疑问词+is/was+it+that….如：
Is it farming that he likes to take up？ Who was it that/who won first in the long jump？
Why was it that he came late？ It was I that came here late this morning，wasn’t it？
⑤注意把强调句型和“it作形式主语，that引导真正主语从句的句型”区别开来。如果
把强调句型的结构标志去掉后，句子结构和意思仍然完整的为强调句型。如：It is natural that he doesn’t do it at all.（主语从句） It was yesterday that I met him.（强
调句型）
注意：强调动词时，不能用强调用句型，可以把助动词do，does，did用于一般现在时
和一般过去时的肯定陈述句中，与动词原形连用，以加强语气，在句中要重读。如：I do think he is right. He did tell me that he would join us in the work.
⑸it引起的几个易混的时间句型。
①It's time…that从句，从句中谓语动词需要用虚拟语气（“should+动词原形”或动
词过去式）如：It's time that we started out/should start out.
②This/It is the first/second…(序数词) time + that 从句（从句中常用现在完成
时态）
This/It was the first/second…(序数词) time + that 从句（从句中常用过去完成
时态）It/This/That +is/was/will be +first（second…）time+that-clause.本结构中，其中的序数词也可以修饰day，month，year等名词。如：This is the second time that she has rung you today.
③It will/won’t be + 时间段 + before从句(从句用一般现在时态)
It was + 时间段 + before 从句（从句用一般过去时态）
注意：这种句式分为两种情况：主将从现，主过从过（即主句用将来时态时，从句用一般现在时态，表示过了多长时间以后即将发生某事；如果主句为过去时态，从句也用过去时态，表示多长时间之后发生了某事。）如：
It won’t be long before he succeeds. It was ten years before they met again.
④It is/has been + 一段时间 + since 从句（从句中常用一般过去时态或现在完成时态）
It was/had been + 一段时间 + since 从句（从句中常用一般过去时态或过去完成时态）
注意：此句型中如果since从句中谓语为延续性动词，翻译时应翻译为否定式。如：It is five years since he (has) arrived in China.
他来中国已经五年了。
It is five years since he (has) smoked a cigar.
他戒烟已经五年了。
注意以上两句的区别。
It was five years since he (had) arrived in China.
⑤It is/was+具体时间点+when…本结构是定语从句句型，具体的时间点是先行词。如：
It is five o'clock in the afternoon when they climb up to the top of the mountain.
（6）it的模糊用法
①it + that 可以引导宾语从句，这样的动词或词组有: see to it（确保），depend on, rely on, insist on, take（猜想、认为）。如：
I take it that he is not fond of reading this novel.
Our teacher saw to it that our homework should be finished on time.
② like, love, appreciate, enjoy, dislike, hate it + 介词短语 + when引导的宾语从句。如：
I hate it in the evening when you sing.
③ make it表示“成功办到、做到、赶上”。如：

最新高中英语语法It的用法专题讲解与练习带答案
It的用法 It的用法在高考中也是重现率较高的语言点，尤其是it用于强调句。其考查方式多通过“单项填空”进行，偶尔也出现在“短文改错”和“完形填空”中。 一、要点点拔 1．用于表达天气、环境、时间、距离、季节等。例如： 1) It?s half an hour?s walk from here to our school． 2) It…s nice and warm here． 3) But it's two o'clock now, and it's time for us to go to school． 2．代替上文中提到过的人或事物。指代人时，一般用于小孩或身份不十分明朗的人。 1) －Who is the baby? －It…s my teacher?s son． 2) －Who is that gentleman? －It's my friend Tom．He(不可用It) wants to see you． 3．用作形式宾语。 当复合宾语中的宾语是不定式,－ing短语或从句往往用it作形式宾语,而将真正的宾语移至句末,句子重心后移。 1) We find it difficult to learn English well in such a short time． 2) We think it no use crying over spilt milk． 3) We made it clear when and where we were going to have the meeting． 4. 用作形式主语.it 没有具体意义，而只是帮助把真正的主语移至句子后尾，使句子显得平稳一些，能借it 给移至句子后尾的主语有三种：一种由不定式表示，一种由动名词表示，一种由从句表示。 1).It 替代真正的主语——动词不定式短语. It is easier to say than to do . It is a good act to help the others. 2).it 替代真正的主语——动名词短语,以动名词短语做主语的句子，主要在以no good, no use, no harm, dangerous, foolish 等词作表语的句中. It?s no harm drinking running water in that area。 It?s foolish talking like that. 3).it 替代从句作主语，用从句做主语的带it 的句子很多,常见的有下面几类： ①It is a pity (a shame ,a fact ,a wonder ,a good thing, etc. ) that… It is a shame that he didn?t pass the exam. ②It is strange ( surprising, obvious ,true, good, possible, clear, etc. ) that…。 It was clear that they had no desire for peace. ③It seems (happened ,turned out, etc.)that… It seemed that things were not as they expected. ④It is said ( decided ,expected ,etc)that … It is said that the tickets have been sold out . 5．用于强调句型，即“It is/was＋被强调部分＋that/who/whom+其它”句型之中。
