Question

If my lawyer ______ here last Friday, he _____ me from telling the truth.

1. A.
   had been; would have prevented
2. B.
   had been; would prevent
3. C.
   were; would prevent
4. D.
   were; would have prevented

Answer 1

A
考查虛擬語(yǔ)氣。根據(jù)時(shí)間狀語(yǔ)last Friday，說(shuō)明指的是過(guò)去的情況，所以if引導(dǎo)的從句要用過(guò)去完成時(shí)，而主句要用助動(dòng)詞+現(xiàn)在完成時(shí)。所以選A。
