题目内容
5.来吧,孩子们!该进行体育活动了.Come on,children.It's time to do the exercises.
分析 It's time to.
解答 答案:It's time to.这里是说客观事实用一般现在时,表示该做某事了用It's time to do sth,故答案是It's time to.
点评 ①It's time to do sth.意为"是做某事的时候了",但没有讲清楚是谁去做.
It's time to go to school.是上学的时候了.
②It's time for sb.to do sth.意为"是某人做某事的时候了",for后面通常接一个表示人的词语,其后的不定式所表示的动作就是这个表示人的词语sb.发出的.例:It's time for you to go to school.是你上学的时候了.
③It's time for sth.也表示"是做某事的时候了",但这个句型中介词for的后面只能是表示物的名词,说明所要做的事情.例:It's time for class.是上课的时候了.
注意:It's time to do sth.和It's time for sth.在一定条件下可相互转换.例:
It's time for supper.=It's time to have supper.该吃晚饭了.
