时态的辨析

一、考查现在完成时的用法之一"过影现"
  
  "过影现"表示过去发生或已经完成的某一动作对现在造成的影响或结果。此时,常与时间副词already(已经),yet(还;已经),just(刚刚;仅仅),ever(曾经),never(从不),before(以前)等连用。注意:already常用于肯定句中,yet用在疑问句中意为"已经",用在否定句中意为"还"。如:
  
  She has lost her bike.她把自行车丢了。("丢"这个动作是过去发生的,对现在造成的结果是"她现在没有自行车骑了"。)
  
  I’ve already read this book.我已经读过这本书了。("读"这一动作发生在过去,对现在造成的影响是"我已知道书中的内容"。)

  2.- Have you finished your homework?

  C.Not a bit
  
  D. Not yet
  
  3.- Your shoes are so old Why don’t you buy a new pair?
  
  - Because I____all my money On an MP5.(2013年广东卷)
  
  A.spend
  
  B.have spent
  
  C. am spending
  
  D.was spending
  
  二、考查现在完成时的用法之二"过延现"
  
  "过延现"表示过去已经开始,延续到现在的动作或状态,甚至还可能继续延续下去。常与for或slnce引出的时间状语连用,动词必须是延续性动词。如:live,study,work,be,wait,know,stay,teach,keep,walk,sleep等。注意:for为介词,后面要接"一段时间";smce用作介词时,后面接"过去的时间点";since用作连词时,后面接"从句"(从句谓语动词用一般过去时)。另外,SO far(至今),up to now(到目前为止)也常与现在完成时连用。如:
  
  Mr. Wang has worked in the factory since he came to the city.自从王先生到这个城市以来,他就在这家工厂工作。
  
  So far, she has learnt about two thousand English words.到目前为止,她已经学了大约2000个英语单词。
  
  The baby has slept for three hours.孩子已睡三个小时了。
  
  温馨提醒:非延续性动词表示某一瞬间就结束的动作,常见的有:come, go, arrive, reach, see, hear, close, open, leave,begin, start, lose, buy, fall, join, die, get up, become, borrow,lend.find,finish,receive等。这些动词可用于现在完成时,说明某个动作的结果还存在,但不能和表示一段时间的状语如how long,for,since连用。可将它们转换为表示延续状态的词,如:buy-have , borrow/ lend-keep, join-be in/be a member of,die-be dead,leave-be away(from),begin-be On等。试体会下列例句:
  
  A他人团两年了。
  
  误:He has joined the League for two years.
  
  正:He has been a League member for two years.
  
  A我买这辆自行车三年了。
  
  误:I have bought this bike for three years.
  
  正:I have had this bike for three years.
  
  A他离开家五天了。
  
  误:He-left home for five days.
  
  正:He has been away from home for five days.

  D.studied in this school
  
  三、考查have/has gone to,have/has been to与have/hasbeen in的区别
  
  have/has been to表示"曾经去过某地",现在人已经不在那儿了;have/has gone to表示"已去了某地",说话时,该人已不在现场,可能在去某地的途中,也可能已经到达目的地,一般不用第一、二人称作主语。注意:后接地点副词时,介词to要省略;have beenin表示"某人在某地",去了某个地方或来到了某个地方多久。

  B.has gone to
  
  C. has been in
  
  D.has been to
  
  四、考查现在完成时与一般过去时的区别
  
  现在完成时与一般过去时都可以表示过去发生的动作,但二者的侧重点不同。一般过去时表示过去某个时间发生的动作或存在的状态,也可表示过去习惯性的动作,不涉及与现在的关系。常与表示过去的具体时间状语连用,如:yesterday,last year,in1998,three years ago等。而现在完成时强调过去发生的某一动作对现在造成的影响或结果,以及过去已开始并延续到现在的动作,与现在有着密切的关系,不能与表示过去的时间状语连用。
