题目内容
4.到课外锻炼的时间了.咱们出去吧.It's time for after school exercise.Let's go out.
分析 It's time for.
解答 答案:It's time for.
表达的是客观事实用一般现在时,表示到做某事的时间了用it's time for sth,for是介词后可加名词,故答案是It's time for.
点评 t's time to跟的是不定式(to do).也就是说,要跟一个动词,意思是"到做某事的时候了".如:
It's time to go home.
It's time to tell him the truth.
It's time for 跟的是名词.也就是说,不能跟动词.如:
It's time for lunch.(没必要说It's time to have lunch)
It's time for class.(没必要说It's time to begin the class.)
