北师大版高中英语语法专题复习; 研究一下近年来的高考试卷可以发现，含 it 的句型几乎年年考到。核心考点：强调句型；it用作形式主语或宾语；固定搭配。现根据其用法特点归纳出下面的24个it常用句型。 ;1. It is/was + 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。 e.g. It was they that (who ) cleaned the classroom yesterday.  It was on Thursday afternoon that he told me about the truth.  It was in the street that I came across one of my friends the other day. ;2. It is/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 didnt realize she was a famous film star until she took off her dark glasses. ;3. It is clear ( obvious, possible, likely,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，可能，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, essential,strange, natural...) that ... 该句型和句型3同属一个句型。由于主句中的形容词不同，that 后的从句中常用虚拟语气（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/was said (reported, believed…) 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，人们相信……）”。 It is said that he has come to realize his miatakes . 　　 It is reported that another man-made satellite has been put into orbit.;6. It is suggested ( ordered, required ... ) that ... 该句型和句型5同属一个句型。主句中的???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 可以省略。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 可省略。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
