因為if 從句,would 所虛擬的事情發(fā)生在過去,主句應(yīng)該用would have done,從句應(yīng)該用had done .
如果是would be的話可以表示現(xiàn)在,將來的虛擬.
在牢記句子使用方法的時候要結(jié)合時態(tài).
If the Houses of Parliament had not been burned down in 1834, the great clock would never have been erected.
If the Houses of Parliament had not been burned down in 1834, the great clock would never have been erected.
這句句子為什么從句用過去完成?
不是不真實的逐句用would家動詞原形,從句用過去時嗎?
為什么不是 If the Houses of Parliament was burned down in 1834, the great clock would be erected.
