It was Mr Zhang that helped us out of the trouble. Without his help, we ______ it so easily.
A．can’t manageB．mustn’t have managed
C．couldn’t have managedD．couldn’t manage
C
本題考查含蓄虛擬語氣。根據(jù)It was Mr Zhang that helped us out of the trouble可知是和過去事實(shí)相反，Without his help，為含蓄虛擬條件，主句謂語應(yīng)用couldn’t + have done 結(jié)構(gòu)，所以選C。
