It 作形式主语的常见句型：1. 代作主语的动词不定式，其句型为（1）It be adj. (for sb.) to do sth.
（2）It be adj. of sb. to do sth.
（3）It替代作主语的动名词的常见句型：
It’s no good/use doing…
It’s (well)worth doing…

2. It替代作主语的从句常见句型
（1）It is + noun +从句
（2）.It is adj. +clause
It’s surprising that… (should)………竟然……
It’s a pity/shame that…(should)………竟然…

1. verb+ it+ adj./noun (for/of) to do/clause (verb=think, believe, suppose, consider, feel, make, keep…)
五、强调句型
It is/was+被强调部分+ that(who)… 强调句型用来强调谓语动词以外的任何句子成分。当被强调部分是人时也可以用who。
在使用强调句型时需注意以下几点：
1. 请注意强调句型的特殊疑问句
2. 在强调原因状语从句时，只能强调由because所引导的从句。
3. 在强调not … until结构时必须把not与until一起放到被强调的位置上。
4. 注意强调句型与定语从句的区别。
