Question

It was Mr Zhang that helped us out of the trouble. Without his help, we ______ it so easily.

A．can’t manage	B．mustn’t have managed
C．couldn’t have managed	D．couldn’t manage

Answer 1

C

本题考查含蓄虚拟语气。根据It was Mr Zhang that helped us out of the trouble可知是和过去事实相反，Without his help，为含蓄虚拟条件，主句谓语应用couldn’t + have done 结构，所以选C。
