They can't have been watching the football match this time yesterday,___?
A.must they
B.can they
C.have they
D.were they
why choose
A.must they
B.can they
C.have they
D.were they
why choose
因为这里can't表猜测或判断,不可能的意思,所以反义疑问词应该对问题本身提问,而不是对判断词提问.所以AB是错的.
为什么C是错的?
首先我们来把原句恢复成陈述句:
They can't have been watching the football match this time yesterday.
注意,这里的can't表示不可能.
再变成肯定句:
They were watching the football match this time yesterday.
为什么can't have been watching对应were watching?
原因是:因为是this time yesterday,所以是过去时态,如果变成can't be watching就变成现在时态了.为了表现推测的内容是过去,所以要用can't have been doing,但这里绝对不是完成时态,所以C是错误的.
