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.
2、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 the first （ second ） time that 该句型要和上一个句型区别开来。该句型中的 that 从句不用虚拟语气，而用完成时态。至于用什么完
6、成时态，由主句的谓语动词的时态决定。如果是一般现在时，后面从句用现在完成时态；如果是一般过去时，后面从句则用过去完成时态。该结构中 that 可以省去；it有时用 this 替换。常译为”是第一（二）次“。It is the first time I have been here. = This is the first time I have been here.10. It is since 该句型主要用作处理瞬间动词的完成时，又要和表示一段时间的时间状语连用的问题。主句中是时间作表语，其时态是现在时或完成时，since 引导的从句通常是一般过去时态，而且是瞬间动词。如果主句是一般过去时，

It takes sb.
9、to do sth.该句型中的不定式是真正的主语，it是形式主语，句型中的直接宾语是时间。常译为”做要花费某人“。It took thousands of people many years to build the Great Wall.15. It is no good （use ） doing sth.该句型中的真正主语是动名词短语，主句中的表语可以是no good , （ not any good ） , no use , （ not any use ）。It is no good learning English without speaking English.16. It doe

13、看起来好象”如果与事实不相符合，则用虚拟语气。It looks as if he is ill.（真的病了）It looks as if he were ill. （没有生病）It seemed as if he were dying.20.
