It句型诠释及练习.doc

It句型诠释含 it 的句型几乎年年考到现根据其用法特点可归纳为下列句型。 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 didnt 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 hes round and tall like a tree. 　　= That hes 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 man-made satellite has been put into orbit 6. It is suggested ( ordered, required ... ) 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
