在现在完成时中，什么时候将瞬间动词变成延续动词~

当句子要跟上表示一段时间的状语如for a long time,for a week , for several days.
he has joined the club.----he has joined the club for two years.错
joined要改成延续动词been in 或has been a a member.

供你参考：
延续性动词与非延续性动词之间的转换：leave --- be away,borrow --- keep,buy --- have,begin/start --- be on,die --- be dead,finish --- be over,join --- be in+组织机构,be a member of+组织机构,open sth --- keep sth open,fall ill --- be ill,get up---be up,catch a cold --- have a cold,come here --- be here,go there --- be there,become --- be,come back --- be back,fall asleep --- be asleep,get to/ arrive/reach --- be (in),leave --- be away from,get to know --- know,go (get) out →be out,put on→ wear；catch a cold →have a cold等.例:The old man died 4 years ago.----The old man has been dead for 4 years.---- It is 4 years since the old man died.----Four years has passed since the old man died.He joined the Party 2 years ago.-----He has been in the Party for 2 years.I bought the book 5 days ago.---- I have had the book for 5 days.

现在完成时之瞬间动词转变成延续性动词
一、for\since:
1)for+一段时间，常常可以发现for+数字，for three months for a long time for many years
2)Since+时间点，常常可以发现
a. since+月份，年份，表示时间的几点 since September since 1990 since 7 o’clock b. since+一段时间+ago； since two years ago since ten months ago
c. since+ last+.... since last month since last year
二、现在完成时的结构式 has\have done 请注意第三人称：she\he\人名...+has
三、当句子为肯定句，且居中出现for\since的时候，句中的时态要用现在完成时，且句中的动词要用延续性动词。
当句子为否定句时，句中的动词可以为瞬间动词，表示某个动作不发生的状态已经持续了......
四、在有for\since的现在完成时的从句中，如何将瞬间动词转换成延续性动词
以borrow——keep为例子
They borrowed it last week. 分析：
1）我们已经知道现在完成时的标志就是has\have done，因此第一步就是看主语，主语时They，我们选择have done。
2）因为borrow——keep.而keep——过去分词：kept，因此，have borrowed就需要改成have kept.
3）Since后面只能接时间点，而last week就是一个时间点，因此，since后面直接填写last week。
五、常考的瞬间动词：
原形 过去式 过去分词 动词原形 动词过去分词
1. die--be dead die died died be dead been dead
2. borrow--keep borrow borrowed borrowed keep kept
3. leave--be away from leave left left be away from been away from
4. buy--have buy bought bought have had
5. begin--be(on) begin began begun be been
6. join--be a member of join joined joined be a member of been a member of be in join joined joined be in been in
1/2
7.become--be become became become be been
8.Open\close--be open open opened opened be open been open
9.finish--be over finish finished finished be over been over
10.put on--wear put put put wear worn
11.catch a cold--have a cold catch caught caught have had
12.go to--be in go went gone be in been in
13.get to know--know get got got know known
14.Arrive in\at--be in arrive arrived arrived be in been in
15.Move\come\get to--be in
16.go out--be out go went gone be been Move\come\get to--be in be in been in
举例
Mr. Smith came to this school in September.
Mr. Smith ___has____ ____been____ at this achool_____since___ September.
分析：
1, come--came--come
2, 本来应该是填写has come to，但是come to要转换成be in
3, 而be的过去分词为been因此我们填写的内容为 has been in
4，因为句子中已经有了at
，所以我们只需要填写has been

表示经过一段时间的完成时需要用延续性动词。
表示某个时间点的过去时用瞬间动词。
如何转变？
基本上没有规律。一般瞬间动词对应的介词和形容词表示延续，具体还是要记住。

南陵县18291364682： 关于现在完成体的瞬时动词与延续性动词间的变换问题. - ？
景腾盐酸： have started/begun to do sth.-->have done sth意思是开始做某事,当我们遇到前面这个(start、begin)瞬间动词用于一段时间(2 hours)时要变为后面这个句型have done sth,done是延续性动词do(这里的do是做的意思),不能用瞬间动词.当我们遇到for +一段时间 或 since+过去的时间点(since 2 years)就要转换为延续性动词.如:open,stop,like,love,die,win,close,shot,begin,start enter,finish 等为瞬间动词用于时间段时都要做相应的变换的,当然要记忆一下的.希望能帮助你,欢迎追问!
