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，表语或状语。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 about 600 years ago that the first clock with a face and an hour hand was made. It was they that (who ) cleaned the classroom yesterday. It was in the street that I met her father. 2. It is 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 ... 该句型和上一个同属一个句型。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。建议记住该句型中的形容词。 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. It is reported that another earth satellite has been put into orbit. 6. It is suggested ( ordered ... ) that ... 该句型和上一个同属一个句型。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. 这种事竟然发生在你们班上，真是遗憾！ It is a pity that he is ill. 他生病了，真遗憾！ 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 ... 该句型要和上一个句型区别开来。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 替换．常译为＂是第一（二）．．．次．．．＂。 It is the first time I have been here. = This is the first time I have been here. 10. It is .... since ... 该句型主要用作处理瞬间动词的完成时，又要和表示一段时间的时间状语连用的问题。主句中是时间作表语，其时态是现在时或完成时，since 引导的从句通常是一般过去时态，而且是瞬间动词。如果主句是一般过去时，从句则用过去完成时。 It is ( has been ) 5 years since his father died. 11. It is ... when ... 该句型中的 when 引导的是一个时间状语从句，主句中的 it 指时间，表语由具体的时间充当。常译为＂当．．．的时候，是．．．＂。 It was 5 o’clock when he came here. 12. It be ... before ... 该句型主句中的 it 指时间, 主句中的时态常是将来一般时或过去时两种时态．主句中的表语多是long, not long , 3 days , 2 weeks 等表示时间段的词或短语。常译为＂．．．之后．．．＂。 It was 3 days before he went to Beijing. It will be not long before he finishes his job. 13. It happens (seems, looks, appears ) that... 该句型中it是形式主语，that 引导的是主语从句，主句中的happen , seem等词是不及物动词． It happened ( so happened ) that he met his teacher in the street. 碰巧．． It seems that he will be back in a few days. 看来．．． 14. It takes sb. ... to do sth. 该句型中的不定式是真正的主语，it是形式主语，句型中的直接宾语是时间。常译为＂做．．．要花费某人．．．＂。 It took thousands of people many years to build the Great Wall. 15. It is no good (use ) doing sth. 该句型中的真正主语是动名词短语，主句中的表语可以是no good , ( not any good ) , no use , ( not any use )。 It is no good learning English without speaking English. 16. It doesn’t matter whether ( if ) ... 该句型中whether(if) 引导的从句是真正主语，该句型常译为 ＂不论（是否）．．．没关系．．．。 It doesn’t matter if they are old. 17. It is kind ( of sb. ) to do sth. 该句型中的不定式短语是真正主语，如果不定式的逻辑主语是由 of引起，主句中的形容词必须是能表示逻辑主语特征的形容词。常见的有： bad , brave , careless, clever , cruel , foolish , good （好心的）, honest , horrible , kind , lazy , modest , naughty , nice（有教养的）, polite, rude , silly , stupid , wise , wrong（错误的）等。 这个句型可以改写为：sb. is kind to do sth. It is kind of you to say so. = You are kind to say so. 18. It is necessary ( for sb. ) to do sth. 该句型与上一个同属一个句型。如果不定式的逻辑主语是由for引起，主句中的形容词通常是表示重要性，紧迫性，频繁程度，难易，安全等情况的形容词。常见的形容词有：① important, necessary, natural ② easy , safe , common , normal , hard , difficult , dangerous , unusual, rare , impossible , pleasant等。 在①中的形容词作表语可以用从句改写，如： It is important for her to come to the party. = It is important that she (should ) come to the party 19. It looks ( seems ) as if ... 该句型中it无意义。 as if 引导一个状语从句。常译为，＂看起来好象．．．＂如果与事实不相符合，则用虚拟语气． It looks as if he is ill.（真的病了） It looks as if he were ill. （没有生病） It seemed as if he were dying. 20. We think it important to learn a foreign language. 该句型中的it 作形式宾语。为了记忆方便我们可称该句型为“6123结构”。 6 指主句中常用的动词：think, believe, make, find, consider, feel； 1 指的是形式宾语 it； 2 指的是宾补的两种形式：形容词或名词； 3 指的是真正宾语的三种形式：不定式短语，动名词短语或that引导的宾语从句。 We think it our duty to clean our classroom every day. He felt it important learning English well. They found it difficult that they would finish their work in two days. 21. It is (just) like sb. to do sth. 该句型为“某人（恰恰）是。。。这个样子”。用来表示赞扬或不满，若用否定式，则表示怀疑。 It’s like him to leave the work to others. 他就是这样的一个人，把工作推给别人。 It isn’t like him to have said anything like that. 他可不是说出那种话的人。 22. It is up to sb. to do sth. 该句型为“该由某人做。。。”。该句型中up后的to是介词。 It is up to him to clean our classroom today. 今天应由他做教室清洁。 It is up to parents to teach their children manners. 该由父母教孩子礼貌。 23. It is one’s turn to do sth. 该句型为“轮到某人做…”。不定式是句子的真正主语。 It is your turn to clean our classroom today. 今天该轮到你做教室清洁。 24. It is no wonder that… 难怪… 在该句型中如果用肯定形式，表示“真奇怪，真是令人惊讶”；wonder前的no还可以用small等词替换，在口语中，It is ….. that可以省略。 It is a wonder that he reused such a good offer. 真奇怪，他拒绝了这样好的帮助。 It is no wonder that he didn’t want to go. 难怪他不愿去。 ＝No wonder he didn’t want to go. 25. We are counting on it that you will come. 该句型中的it是一个形式宾语，表示模糊意思或代替后面that 引导的宾语从句。因为在这个句型中的谓语动词都是需要跟宾语的，但又不能直接跟从句作宾语，于是就得在从句前加上一个形式宾语it。常见的短语和动词有：count on (依靠，指望，期盼), see to(负责), depend on (依靠), rely on(信赖，依靠), look forward to (盼望),等。 We are counting on it that you will come. 我们一直盼望着你来。 You may rely on it that she won’t be late. 你也许指望她不会迟到。 I’ll see to it that everything is ready. 我将负责把一切都准备好。 They are looking forward to it that Mis Li will come back from the USA. 还有一些动词只能跟it + that从句而不能跟复合宾语。 I like it that …. I take it that he approves. 认为，猜想 love, hate, take, like 实践证明经常访问无忧英语教育网 www.51education.net ,能迅速提高你的英语学习能力!积沙成塔,不断提高! 本站所提供的所有信息仅供学校课堂教学及英语学习者学习研究之用，其著作权归原作者及媒体所有。 |
