   1. 非延续性动词可用来表示某一动作完成,因此可用于现在完成时。如:


  The train has arrived. 火车到了。
  Have you joined the computer group? 你加入电脑小组了吗?
  2. 非延续性动词表示的动作极其短暂,不能持续。因此,不可与表示一段时间的状语连用(只限肯定句)。如:
  (1) 他死了三年了。
  误:He has died 1 for three years。
  正:He has been dead 2 for three years。
  正:He died three years ago。
  正:It is three years since 3 he died。
  正:Three years has passed since he died。
  (2) 他来这儿五天了。
  误:He has come here for five days。
  正:He has been here for five days。
  正:He came 4 here five days ago。
  正:It is five days since he came here。
  正:Five days has passed since he came here。
  (1)、(2)句中的die、come为非延续性动词,不能与表示“时间段”的状语连用。那么,应如何正确表达呢?可以采用下面的四种方法:
  a. 将句中非延续性动词转换为相应的延续性动词,如上面两例中的第一种正确表达方式。下面列举几例:leave→be away, borrow→keep, buy→have, begin/start→be on, die→be dead, move to→live in, finish→be over, join→be in/be a member of, open sth.→keep sth. open, fall ill→be ill, get up→be up, catch a cold→have a cold。
  b. 将句中表示“时间段”的状语改为表示过去确定时间的状语,如下面两例中的第二种正确表达方式。
  c. 用句型"It is+段时间+since..."表达原意,如上面两例中的第三种正确表达方式。
  d. 用句型"时间+has passed+since..."表达原意,如上面两例中的第四种正确表达方式。
  3. 非延续性动词可用于现在完成时否定式中,成为可以延续的状态,因而可与表示“时间段”的状语连用。如:
  He hasn't left here since 1986. 从1986年以来他就没离开过这里。
  I haven't heard from my father for two weeks. 我已经两周没收到我父亲的来信了。
  4. 非延续性动词的否定式与until 5/till连用,构成"not+终止性动词+until/till..."的句型,意为“直到……才……”。如:
  You can't leave here until I arrive. 直到我到了,你才能离开这里。
  I will not go to bed until I finish drawing 6 the picture tonight. 今天晚上直到我画完画,我才去睡觉。
  5. 非延续性动词可以用于when引导的时间状语从句中,但不可以用于while引导的时间状语从句中。
  因为when表示的时间可以是“时间点”(从句谓语动词用非延续性动词),也可以是“时间段”(从句谓语动词用延续性动词);而while表示的是一个较长的时间或过程,从句谓语动词要用延续性动词。如:
  When we reached 7 London, it was 8 twelve o'clock。(reach为终止性动词)
  Please look after my daughter while/when we are away。(be away为延续性动词短语)
  6. 终止性动词完成时不可与how long连用(只限于肯定句)。如:
  误:How long have you come here?
  正:How long have you been here?
  正:When did 9 you come here?
