Question

求助英语问题。

问题：he has been an army man for five years.
为什么不可以写成：he has been joined the army five years.有什么语法问题呢？

Answer 1

可以写成He has joined the army five years.

第一个句银烂子里been做动锋野漏词,
你那个句子里已经有join这脊返个动词了, 不需要been.

Answer 2

join是点动词，非持续
所以不能与一段时间连用，如for five years

Answer 3

rugu如果是你说的后一简春种应该局态是
he has been joined the army five years ago.
join shi是不延续词拦腊耐

Answer 4

joined 是一瞬间的,不能持续五年.

Answer 5

如果是下面的那种写法应该用过去时
