意思基本一样,不过to便是要做什么,for有表示状态的意思. it's time to +动词词组 经常是It's time to do sth it's time for +名词 It's time for supper. =It's time to have supper. It's time for class. =It's time to have class. 注意英文是一种很注重形式的语言,不能搭配错了. time for +名词(通常不包括动名词)-------- It is time for bed. time to +动词原形----- It is time to go to bed.
