whenever 可以作连词conj用,意思是”每当”,“无论何时”,相当于no matter when。例如:
1.whenever we met with disabilities,they came to help us.=No matter when we met with disabilities,they came to help us.
2.we try to help whenever(it is) possible.=we try to help no matter when(it is )possible.
whenever还可以作副词用,用在疑问句中,表示惊奇,意思是“究竟什么时候”,例如:
3.whenever did I make such a promise?
