选择题
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
答案
答案：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。
