Question

写出同义句 My brother has been a party member for a year. My brother ___ ___ ___ last year.

Answer 1

question:how
long
has
your
brother
worked
as
a
waiter?(你弟弟做服务生做多久了？）
answer:my
brother
has
worked
as
a
waiter
since
last
year（我弟弟从去年就开始做服务生了）
说明：
1）这是一个典型穿花扁拘壮饺憋邪铂矛的现在完成时的语态。强调的是一个持续的状态（从去年到现在一直都在做服务生）。
2)强调一个持续状态的时候，疑问句是用“how
long”，强调点状态的时候用“when”.比如下面的一疑问句，when
did
your
brother
work
as
a
waiter?
这句话是说“你弟弟什么时候做的服务生？”这明显是个点状态。如果把这句当成答案，那回复的时态就不应该是现在完成时，而是一般过去时。
不知道我解释的清楚了没有，请楼主自行比较。注意时态。
