could have done的格式是表示對過去的推測
從 why didn't you tell me看出,這正是對過去的推測
而might還是對現(xiàn)在的推測,雖然用過去式的樣子,但是不是過去式,只是語氣的委婉
we ( ) the difficulty together,but why didn't you tell me?
we ( ) the difficulty together,but why didn't you tell me?
A.could face B.might face C.could have faced D.must have faced
為什么選C不選B
A.could face B.might face C.could have faced D.must have faced
