It’s hard to imagine what rock would be like if there had not been English performers such as the Beatles, the Rolling Stones, and David Bowie.
请问老师,if这个句子是对过去情况的虚拟吗,主句没有用would/ could / might have done?
what rock would be like if there had not been English performers such as the Beatles, the Rolling Stones, and David Bowie 这个复合句作 imagine 的宾语。这个复合句是一个错综时间条件句:表示因过去的假定而出生现在的结果,从句用过去假定,主句用现在假定,即:if 条件句的谓语动词用“ had + 过去分词”,主句的谓语动词用“ should /would /could / might + 动词原形”。
