He has__the army for ten years and is now an officer. A.gone into B.joined in C.been in D.come into
答案是C，请问4个选项表示什么？B为什么不行？谢谢。

Answer 1

C
翻译：他参军十年而且现在是一名军官。
现在完成时中，for后面是时间段，表示这个工作在持续进行着，所以必须使用可延续性的动词，

ABCD都是加入的意思，只不过ABD动词都是短暂性动词，不能延续，所以淘汰

不明请追问。

不好意思，请问如何区分短暂性动词与延续性动词。谢谢。

追答

这些词需要记下来 靠着理解来记忆比如说start 开始，开始这个动作不能一直进行吧，如果一直进行就不叫开始了，所以它就是短暂性的，下面列出常用的短暂性动词，以及相对应的延续性动词。
arrive→be here begin(start)→be on
die →be dead come back→be back
leave →be away (from) fall ill(sick, asleep)→be ill(sick, asleep)
get up→be up go out →be out
finish →be over put on →wear 或be on
open →be open join →be in或 be a member of…
close →be closed go to school→be a student
borrow →keep buy/get →have
catch(a cold)→ have(a cold) get to know →know
begin to study→study come to work→work
move to → live in finish/end → be over
come to → be in sit down → be seated
marry → be married dress → be dressed等
