Since the road is wet this morning,_____last night.A.it must rain B it must have have rianed Cit must be rianed As the physics is hard enough,i ____study it.A can't B cannot C amnot able toquestion1:can't和cannot有什么区别
1.B不过应该是it must have rianed (现在完成时,表过去发生的事情(昨晚下雨了)对现在造成的影响(地上是湿的))
2.C(物理题太难了,做不出来(即能力不够))
很简单一个记法,表肯定意思就是must,表否定意思就是can't(not be able
to)
can't和cannot没有区别,缩写而已
Since the road is wet this morning,_____last night.
B,
因为有since
C must have done表示对过去的肯定猜测。。 因为早上路是湿的,所以昨晚肯定下雨了。
C be able to 表示能力,因为物理很难,所以我没有能力学
can't 跟cannot的区别: 两者意思一样,一个作为口头语,一个作为书面语
第一个空选B 使用的是过去完成时
