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的用法训练题
综合训练十：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“语法填空”进行，偶尔也出现在“完形填空”中。 一、要点点拔 1．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． 2．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． 3．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 . 4.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． 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。 使用该句型有以下几点请注意： ①强调句的谓语is或was永远用单数. It was yesterday that I met your father in the street． ②不管被强调部分是哪种状语，只能用that连接，不得使用where、when等连词. It was in the street that I met your father yesterday．

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。
