= That he’s round and tall like a tree is very clear.

⑵It is important ( necessary，right，strange，natural...) that 从句常译为┅是重要的(必要的,对的,奇怪的,自然的┅).that 后的从句中要用虚拟语气（should + 动词原形），should 可以省去，建议记住该句型中的形容词。

①It is important that we (should) learn English well.

②It is necessary that he (should) remember these words.

⑶It is said (reported/ learned/believed/thought/known/told/hoped.....) that 从句常译为＂据说（据报道，据悉．．．）＂。

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)

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

高中英语语法知识之It的用法总结

高考英语语法知识之It 的用法总结 1．It is + 被强调部分+ that ... 该句型是强调句型。将被强调的部分放在前面，其它部分置于that之后。被强调部分可以是主语，宾语，状语。强调的主语如果是人，that可以由who换用。 如果把这种句型结构划掉后，应该是一个完整无缺的句子。这也是判断强调句型与其它从句的方法。 It was they that (who) cleaned the classroom yesterday. It was in the street that I met her father. 2．It was not until + 被强调部分+ that ... 该句型也是强调句型。主要用于强凋时间状语，译成汉语＂直到．．．才．．．＂，可以说是not ... until ... 的强调形式。 It was not until she took off her dark glasses that I realized she was a famous film star. = Not until she took off her dark glasses did I realize she was a famous film star. = I didn’t realize she was a famous film star until she took off her dark glasses. 3．It is clear ( obvious, true, possible,certain....) that ..... 该句型中it 是形式主语，真正的主语是that 引导的主语从句，常译为＂清楚（显然，真的，肯定．．．）＂是主语从句最常见的一种结构。 It is very clear that he’s round and tall like a tree.= That he’s round and tall like a tree is very clear. 4. It is important ( necessary, right, strange, natural...) that ... 由于主句中的形容词不同，that 后的从句中要用虚拟语气（should + 动词原形），should 可以省去。 It is important that we (should) learn English well. It is necessary that he (should) remember these words. 5. It is said (reported, learned....) that ... 该句型中的it 仍是形式主语，真正主语是that 引导的主语从句。该结构常译为＂据说（据报道，据悉．．．）＂。It is said that he has come to Beijing. 6. It is suggested ( ordered ... ) that ... 主句中的过去分词是表示请求，建议，命令等词时，that后的从句要用虚拟语气（should + 动词原形），should 可以省。常译为＂据建议；有命令．． It is suggested that the meeting ( should ) be put off. It was ordered that we ( should ) arrive there in two hours. 7. It is a pity ( a shame ... ) that ... 该句型中，that后的从句一般用虚拟语气（should + 动词原形），should可省去．表示出乎意料，常译为＂竟然＂。没有这种意义时，则不用虚拟语气。 It is a pity that such a thing ( should ) happen in your class. It is a pity that he is ill. 8. It is time ( about time ,high time ) that ... 该句型中that 后的从句应该用虚拟语气，值得注意的是①常用过去时态表示虚拟．②有时也用should + 动词原形，should 不能省。常译为＂是（正是）．．．的时侯．．．＂。 It is time that children should go to bed. = It is time that children went to bed. 9. It is the first ( second ... ) time that ... 该句型中的that 从句不用虚拟语气，而用完成时态。至于用什么完成时态，由主句的谓语动词的时态决定。如果是一般现在时，后面从句用现在完成时态；如果是一般过去时，后面从句则用过去完成时态。该结构中that 可以省去；it有时用this / that 替换．常译为＂这是某人第几次做某事了＂。 It is the first time I have been here. = This is the first time I have been here. 10 It is the +形容词最高级+ 名词+ that + ….. 该句型中的that 从句不用虚拟语气，而用完成时态。至于用什么完成时态，由主句的谓语动词的时态决定。如果是一般现在时，后面从句用现在完成时态；如果是一般过去时，后面从句则用过去完成时态。该结构中that 可以省去；it有时用this / that 替换．常译为＂这是某人做过的最…的事情＂。 This is the best film that I have ever seen .
