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.4.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 said (reported, learned....) 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．．．）”。

该句型中的 that 从句不用虚拟语气，而用完成时态。
至于用什么完成时态，由主句的谓语动词的时态决定。

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 )。

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.18.It is necessary ( for sb. ) to do sth.该句型与上一个同属一个句型。
假如不定式的逻辑主语是由for引起，主句中的形容词通常是表示重要性，紧迫性，频繁程度，难易，安全等情况的形容词。
常见的形容词有：① important, necessary, natural ② easy , safe , common , normal , hard , difficult , dangerous , unusual, rare , impossible , pleasant等。
在①中的形容词作表语可以用从句改写，如：It is important for her to come to the party. = It is important that she (should ) come to the party.19.It looks ( seems ) as if ...该句型中it无意义。
as if 引导一个状语从句。
