这个很多的啊。。你得具体给出一个单词无法具体得给出所有延续性和瞬间性动词。 其实判断的方法是否是延续性的是有的。 比如说，死。在中国我们可以说他死了好久了。但是在英文中不可以这么说，因为死是一个瞬间性的动词。不能说他死这个动作持续了多久。所以在完成时中得改成be dead。一个形容词的形式、 再比如说，居住。在中英文中都可以表示出持续的住了多久的。所以这是一个延续性的动词。...

buy-have put-on wear catch/get a cold-have a cold come/go/become-be in根据动词所表示的动作能否延缓,分为延续性动词和短暂性动词.可以表示持续的行为或状态的动词,叫做“延续性动词”,也叫“持续性动词”,如：be,keep,have,like,study,live,etc.有的表示短暂、瞬间性的动词,叫做“短暂性动词”,也可叫“终止性动词”,或“瞬间性动词”,如die,join,leave,become,return,reach,etc.终止性动词构成的现在完成时,不可以用表示一段时间的状语（如：since 和for引导的短语）来修饰,终止性动词构成的现在完成时,只表示动作发生的因果关系,不能表示动作的延续,因此不能用表示一段时间的状语来修饰.如可以说：The Red Cross has already started for the earthquake-stricken area.但不可说：The Red Cross has already started for the earthquake-stricken area for three days.因为start是终止性动词,它所表示的动作短促,当红十字会出发时,start这个动作便结束了,不可能延续两天.如何解决这个矛盾呢,下面我来归纳一下解决这对矛盾的四种方法.1.用ago时间状语短语来代替since或for引导的时间状语：eg.Mr.Richard has returned from America for two years.(wrong)Mr.Richard has returned from America since two years ago.(wrong)应改为:He returned from America two years ago.2．用It is… since…复合句代替简单句 eg.It has been/is two years since Mr.Richard returned from America.注意：以上两种办法适用于所有终止性动词.3．用相应的形容词和副词代替终止性动词.eg.Mr.Richard has been back from America for two years.4．用延续性动词代替终止性动词.eg.He has gone to the Internet for six hours.(wrong)应改为:He has been on the Internet for six hours.但须注意：终止性动词的否定式可以和since 或for 引导的时间状语连用.因为终止性动词的否定表示的是一种可以延续的状态.eg.I have heard from my friend in Africa for half a year.(wrong)I haven’t heard from my friend in Africa for half a year..(right)

给你说简单一点，borrow就是借书那个动作，keep就是表示你你处于借书的状态
我问的是类似的单词
borrow是借的动作，是借的瞬间，而keep是一直保持着被你借的状态，其实是”保存“的意思。
