题目内容
1.Keeping studying hard is very important for all of you(改为同义句)It is very important for all of you tokeep studying hard.
分析 坚持努力学习对我们所有人来说很重要.
解答 答案:It,keep.原句是动名词短语作为主语,结合下文is very important for all of you to用it作为形式主语,动词不定式做真正主语,构成it's+adj+for sb+to do sth对某人来说做某事是怎样的,故答案是It,keep
点评 t's adj of sb to do sth 中adj 是针对事件,修饰sb
It's adj for sb to do sth 中adj 是针对sb,修饰事件
用of常用于描述人的性质 友好、可恨、善良等.
用for常用于描述事情的性质 容易、重要、关键
例如:It"s very nice (kind,friendly) of you to help me carry the baggage.
你真友好,帮我搬了行李.
