关于现在完成时态的归纳
  1. 现在完成时态的结构have/has+过去分词
  2. 现在完成时涉及两个时间概念。一是过去,二是现在。谓语动词虽然所表示的动作发生在过去,但是该时态所强调的还是对现在的影响或结果。关键在于这种影响和结果正是说话人的兴趣所在。因而,该时态通常不带有时间状语。如:
  The boy has come back.  孩子回来了。(意思是说孩子在家。)
  I’ve lost my pen.  我把钢笔给丢了。(意思是说我现在没有钢笔用。)
  3. 现在完成时态还可以用来表示开始于过去,且该状态一直延续至今而且还有可能继续下去的可能性的情况。谓语动词的动作通常是可持续的。如:
  I have lived here for more than twenty years.  我在此住了二十多年了。
  Nothing has happened ever since.  打那以后就什么也没有发生过,
  4. 非延续性动词用于现在完成时态的时候,通常不带表示时间段的时间状语,因此不和for或者since连用。例如,不能说:I have bought the house for two years / since two years ago.
  而应当说:I bought the house two years ago.
  或者说:I have had the house for two years.
  或者说:It’s two years since I bought the house.
  但是非延续性动词的否定式可以和表示一段时间的时间状语连用,表示这种动作的否定状态的延续。如:I haven’t bought anything for a week / since you left.
  我已经有一个礼拜没有买东西了。/自从你离开以后我没有买过任何东西。
  5. 同学们应当特别注意的是,现在完成时态是一个属于现在时态的范畴,所以它可以和包括“现在时刻”在内的时间状语连用。如:
  Now, today, this morning / week / month / year, by now, so far, up to now, already, before, just, ever, never, always, recently, lately.等等。如:
  I have done nothing today. 我今天什么事情也没有干。
  We have had four lessons this morning.
  今天上午我们上了四节课。(说话时还没有超出上午的范围)
  Have you seen her before?  你以前见过他吗?
  6.当强调行为的行为时间、执行者、行为方式、行为场所、行为原因时,句中一般用一般过去时,而不用或者很少用现在完成时,间或用现在完成时也是为了强调结果。如:Who did it? How did he do it? Why did he do it? Where did he do it? When did he do it?
  
三、典型例题解答与分析
例1 I don’t think the girl is right, ________ ________?
  A. do I B. is she C. isn\'t she D. does she
  解析 答案B。一般来说含有宾语从句的句子改为反意疑问句时,疑问部分常与主句的主谓语要一致,但主句的主语是第一人称时,疑问部分常与从句的主谓要一致。本句中从句的动词为be,且前面表示否定,这样A、C、D都不合题意,B是正确答案。
例2 单项选择填空
( ) 1. The old writer lives ________, but he doesn\'t feel ________.
  A. alone; alone B. alone; lonely  C. lonely; lonely D. lonely; alone
( )2. There are bookshops on ________ side of the street. _________ of them do not close till midnight. A. both; All     B. every; None  C. either; Some   D. other; Many
( )3. I don’t like this movie, ________.  A. either  B. neither  C. too  D. also
( ) 4. I don’t know if he ________ tomorrow. If he ________, I’ll call you.
  A. comes; comes B. will come; will come C. will come; comes D. comes; will come
解析
  1.B. alone可用做副词,意思是“单独的;独自的”。形容词lonely可作表语,意思是“孤独的;寂寞的”,指心理上感到寂寞、孤独等。
  2.C.“在街道两边”要说on half sides of the street或者 on either side of the street。选项 A中的 both不能接side。选项B中的every表示三者和三者以上的每一个,故B不符合题意。如果要表达“在街道的另一边”应为on the other side of the street。选项D中other前没有冠词the.因此选C。
  3.A.either和too意思均为“也”,做副词用时放在句末,但either用在否定句中,too和also用在肯定句中。
  4.C.第一个if引导的是宾语从句,主句谓语动词的时态用现在时,从句可用现在时或将来时。第二个if引导的是条件状语从句,谓语动词的时态要用现在时表示将来。句中tomorrow提示从句应用将来时,所以选C。
例3 下列各句A、B、C、D中有一处错误,将错处序号填入题前括号内并在后面横线上写出正确的答案
( ) 1. How long have the Whites arrived in China?________
    A      B    C D
( ) 2.
