英语的几个问题.
1.Never before has he failed to live up to what his parents expect of him more than it is today 这句话的意思是?
2.-Have you been to the United States?
- Yes,only once.I (stayed) there only for seven days
请问括号里可以用have stayed么,为什么?

Answer 1

他从来没有比今天这样让他的父母更失望
第二题,如果你要用完成时的话,就应该是：I have been there only for seven days,必须用延续性动词,不能用瞬时性的
