7.I think it best that you should do more exercise.

8.He found it difficult to accustom himself to getting up early.

9.She thought it no good worrying about him.

思考：找出1-6句的主语____________. 找出7-9句的宾语___________

归纳：①.1-6句中的it为形式主语，没有真正的意义，它的作用是帮助把真正的主语移至句子的后面，使句子显得平衡，句

子的真正主语是句中的to do/doing/that从句。

②.7-9句中的it为形式宾语，句子真正宾语是句中的to do/doing/that从句。

例如：It is difficult for him to give up smoking.

形主系表主语

She thought it no good worrying about him.

主谓形宾宾补宾语
