  (2) 表示一个动作正在进行时,另一个动作突然发生了。
  时间状语:at this time yesterday, at that time(在那一刻)或以when、while引导的谓语动词是一般过去时的时间状语等。

  几种常见时态的相互转换
  英语中的几种时态在一定情况下可以互相转换,以下是几种常见的转换形式:
  一、 一般过去时与现在完成时的转换
  在现在完成时中,延续性动词能与表示一段时间的状语连用,瞬间动词却不能。
  I have bought a car.
  I have had the car for 3 weeks
  I haven’t bought anything for 3 months
  但是,可用别的表达方式:①瞬间动词用于“一段时间 + ago”的一般过去时的句型中;②瞬间动词可改成与之相对应的延续性动词及短语,与一段时间连用;③瞬间动词用于“It is + 一段时间 + since + 一般过去时”的句型中,表示“自从……以来有……时间”的意思,主句一般用it is来代替It has been;④瞬间动词用于“Some time has passed since + 一般过去时”的句型中。请看:
  A. He joined the League [li:ɡ] 联盟two years ago.
  B. He has been in the League for two years.
  C. It is two years since he joined the League.
  D. Two years has passed since he joined the League.
  二、 一般现在时与现在进行时的转换
  在一般现在时中,at加上名词表示“处于某种形态”,如at work(在工作), at school(上学、上课)等。彼短语可与进行时态转换。请看:
  Peter is at work, but Mike is at play.
  Peter is working, but Mike is playing.
  三、 现在进行时与一般将来时的转换
  在现在进行时态中go, come, leave, start, arrive等动词常与表示将来的时间状语连用表示将要发生的动作。如:I am coming, Mum! 意为“人就来,妈妈!”请看:
  The train is leaving soon.
  The train will leave soon.
  四、“be going to+动词原形”与“will(shall)+动词原形”结构的转换
  “be going to+动词原形”、表示打算、计划要做的事;将来时“will(shall)+动词原形”结构在书面语中,当主语为第一人称时,常用助动词shall。在口语中,所有人称都可以用will。请看:
  We are going to visit the Great Wall next Sunday.
  We shall visit the Great Wall next Sunday.
  动词时态考点分析
  一、根据时间状语确定时态的原则
  1. Hurry up! The play for ten minutes.
  A. has begun B. had begun C. has been on D. began
  [析] 1.since后接时间的起点,for后接时间段,主句动词用现在完成时,应注意瞬间动词与延续性动词的使用。
  二、特殊疑答句
  2.How staying? for five days.
  A.long they will be B.they will be
  C.long will they be D.long they be
  [析] 特殊疑答句 特殊疑答词(when,where,who,how ,etc.)+一般疑答句
  三、根据上下白已有时态信息点确定时态的原则
  3. –When this kind of computer ?
  --Last year.
  A. did; use B. was; used C. is; used D. are; used
  [析] 彼例由下句的时间状语推断出一般过去时态,并且要考虑到被动语态。
  本用上下白语意确定时态的原则
  4. –Hi! Lin Tao. I didn’t see you at the party.
  --Oh, I ready for the maths exam.
  A. am getting B. was getting C. got D. have got
  [析] 彼例由didn’t, at the party推断出应用过去进行时。
