形式主语高考真题 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. It is important ( necessary， 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. It is important that we (should) learn English well. It is said (reported， learned....) that ... It is said that he has come to Beijing. It is reported that another earth satellite has been put into orbit. It is suggested ( ordered /demanded/insisted/commanded... ) 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. 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. 他生病了，真遗憾！

It is the first ( second ... ) time that sb has/have done sth It was the first time that sb had done sth

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.
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．才．．”。
It was 3 days before he went to Beijing. It will be not long before he finishes his job. It happens (seems， 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 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. 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 ， foolish ，honest ， horrible ， kind ， lazy ， modest ， naughty ， nice polite， rude ， silly ， stupid ， wise 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. …

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。 I didn’t realize she was a famous film star until she took off her dark glasses.
