替代作主语的从句、动词不定式、动名词， 而把真正作主语的从句、动词不定式、动名 词置于句尾。 三、 it 用作形式主语
（ 1 ） It be adj. （ for sb. ） to do sth. 此处 adj. 通常为描述事件的形容词： easy ， difficult ， hard ， necessary ， unnecessary ， possible ， impossible ， likely ， unlikely ， right ， wrong ， important ， unimportant ， legal ， illegal ， well-mannered ， ill-mannered ， polite ， impolite ， clear ， obvious ， certain ， suitable ， proper ， fit ， useful ， useless ， dangerous… It is illegal （ for a teenager ） to drive a car without a license. 1. 代作主语的动词不定式
（ 2 ） It be adj. of sb. to do sth. 此处 adj. 通常为描述人的形容词： kind ， unkind ， nice ， rude ， cruel ， considerate ， thoughtful ， thoughtless ， careful ， careless ， silly ， foolish ， stupid ， clever ， wise ， crazy. It’s kind of you to help me with the problem.
It's no good/use doing… It's （ well ） worth doing… It's （ well ） worth one's while doing/to do… It's （ well ） worth while doing/ to do It's no use crying over spilt milk. (3) It 替代作主语的动名词的常见句型
2. it 作形式主语替代主语从句 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 …… ） ” 是主语从句最常见的一种结构。例如： It is very clear that he’s round and tall like a tree. ① It is adj. +clause
It is said (reported/ learned/believed /thought/known/told/hoped.....) 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. ② It is v-ed that…=sb./sth. is to do
③ It is + noun + 从句 It is a pity (a shame /an honor /a good thing/a fact /a surprise/... ) 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。例如： 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！
四、 it 作形式宾语 当复合宾语中的宾语是不定式、动名词宾语从 句时，往往把宾语放在它的补足语后面，而用 it 作形式宾语，放在宾语补足语之前。 该句型中的 it 作形式宾语，常用的动词有 think, believe, make, find, consider, feel 等。 6123
