Ask & Learn闻问切英语口语:she should have dieds
1. 读者Jerry Chanson想知道在It's so unfair that she should have died so young一句,为什么she后面用have而不是has。
2. 另外,Teddy问下面句子的动词,应该是buy 还是bought:
Until the end consumers bought /buy (?) the products, no one in the supply chain has actually sold.
1. Should像其他的auxiliary verb(助动词,如must、would、may、can 等),后面的动词都是verb infinitive,尽管主词是单数。因此,Jerry的句子的主词虽然是she,后面还是she should have而不是she should has。
2. 由于这句的main clause的动词是present perfect tense(has sold),所以dependent clause的动词应该用present tense(buy)。相反,如果main clause采取past perfect(had sold),那么dependent clause的动词就应该变成past tense(bought)了。
