it is the third time you have arrived late this month.
问题描述:
it is the third time you have arrived late this month.
1.为什么用现在完成时而不是过去完成时?
2.句中的arrived为什么不能替换成reached?
答
1,这里涉及到一个句型,It / This is +the+序数词+time+(that)+sb have / has done sth或者It was +序数词+time+ sb had done sth,意思是“这是某人第几次做某事了”.这是一个固定的用法,前面主句和后面从句的时态要求都是固定的,要记住.楼主的题目正是属于第一种情况.
此外,这种用法还可以改为相应的不定式结构,意思不变.
tt is the third time you have arrived late this month.=It /This is your third time to arrive late this month=You have arrived late for three times this month.
2,arrived是不及物,可单独使用;reach 是及物动词,后面要跟相应的宾语.
