2、， the other day， in 1982等。when， after， as soon as 引导的时间状语从句，表示主句动作开始的时间。Where did you go just now？2)表示在过去一段时间内，经常性或习惯性的动作。When I was a child， I often played football in the street.Whenever the Browns went during their visit， they were given a warm welcome.3)句型：It is time for sb. to do sth“到时间了”“该了”I

4、ine was an invalid all her life.(含义：她已不在人间。)Christine has been an invalid all her life.(含义：她现在还活着)Mrs. Darby lived in Kentucky for seven years.(含义：达比太太已不再住在肯塔基州。)Mrs. Darby has lived in Kentucky for seven years.(含义：现在还住在肯塔基州，有可能指刚离去)注意：用过去时表示现在，表示委婉语气。1)动词want， hope， wonder， think， intend 等。Did you

5、want anything else？I wondered if you could help me.2)情态动词 could， would.Could you lend me your bike？例题：Your phone number again？ I _ quite catch it.Its 69568442.A. didnt B. couldnt C. dont D. cant答案A. 本句虽没有明确的时间状语，但从语意上看出，在听的时候没有听懂这个动作发生在过去，因此应用过去时。(二)现在完成时1、表示到现在为止这一时期中发生的动作或情况，即多次动作的总和。eg. We have l

6、earnt four English songs this month.How many times have you read the novel？For many days we havent seen each other.2、表示对现在有影响的某一已发生的动作。eg.

7、f this month， since， for 短语，连词 since 引导的时间状语从句。(三)一般过去时与现在完成时的区别1)过去时表示过去某时发生的动作或单纯叙述过去的事情，强调动作；现在完成时表示过去发生的，强调过去的事情对现在的影响，强调的是影响。2)过去时常与具体的时间状语连用，而现在完成时通常与模糊的时间状语连用，或无时间状语。一般过去时的时间状语：yesterday， last week，ago， in1980， in October， just now， 具体的时间状语共同的时间状语:this morning， tonight， this April， now， once，

8、before， already， recently，lately现在完成时的时间状语for， since， so far， ever， never， just， yet， till / until， up to now， in past years， always，3)现在完成时可表示持续到现在的动作或状态，动词一般是延续性的，如live， teach， learn， work， study， know.过去时常用的非持续性动词有come， go， leave， start， die， finish， become， get married等。举例：I saw this film yester

9、day.(强调看的动作发生过了。)I have seen this film. (强调对现在的影响，电影的内容已经知道了。)Why did you get up so early？(强调起床的动作已发生过了。)Who hasnt handed in his paper？(强调有卷子，可能为不公平竞争。)She has returned from Paris. 她已从巴黎回来了。She returned yesterday. 她是昨天回来的。He has been in the League for three years.(在团内的状态可延续)He has been a League memb

10、er for three years.(是团员的状态可持续)He joined the League three years ago. ( 三年前入团，joined为短暂行为。)句子中如有过去时的时间副词(如 yesterday， last， week， in 1960)时，不能使用现在完成时，要用过去时。(错)Tom has written a letter to his parents last night.(对)Tom wrote a letter to his parents last night.(四)过去进行时表示过去某时正在进行的状态或动作。过去进行时的主要用法是描述一件事发生的

11、背景；一个长动作发生的时候，另一个短动作发生。常用的时间状语this morning， the whole morning， all day，yesterday， from nine to ten last evening， when， whileeg: My brother fell while he was riding his bicycle and hurt himself.It was raining when they left the station.When I got to the top of the mountain， the sun was shining.例题：1)M

12、ary _ a dress when she cut her finger.A. made B. is making C. was making D. makes答案C。割伤手指是已发生的事情，应用过去时。同时，when表时间的同时性，“玛丽在做衣服时”提供事情发生的背景，因此用过去进行时。2)As she _ the newspaper， Granny _ asleep.A. read；was falling B. was reading； fellC. was reading；was falling D. read；fell答案B。句中的as = when， while，意为“当之时：。描

13、述一件事发生的背景时，用过去进行时；一个长动作发生的时候，另一个短动作发生。句意为”在她看报纸时，奶奶睡着了。“句中的 fell (fall的过去时)，是系动词，后跟形容词，如：fall sick。【巩固练习】1、My mind wasnt on what he was saying， so Im afraid I _half of it .A. was missing B. had missedC. will miss D. missed思路分析：本题考查动词的时态。所提供的选项包括过去进行时、过去完成时、一般将来时和一般过去时。过去进行时表示过去某一点时间正在发生的动作；过去完成时表示“过

14、去的过去”，一般将来时表示将要发生的动作，都不符合题意。这里用一般过去时表示一个具体的动作。答案：D2、I hear Jane has gone to the Holy Island for her holiday .Oh， how nice！ Do you know when she _？A. was leaving B. had leftC. has left D. left思路分析：该题问的是“她什么时候离开的”。只涉及过去的一个具体动作，与现在无关，所以用一般过去时。答案：D3、I _you not to move my dictionary now I cant find it.A.

15、 asked B .askC. was asking D. had asked思路分析：该题考查时态的运用。从语境看，“我现在找不到词典了”，说明 ask这个动作发生在过去。过去进行时表示过去正在发生的动作，而过去完成时表示在过去某个时间以前发生的动作，显然都不符合语境。答案：A4、More patients _in hospital this year than last year.A. treated B. have treatedC. had been treated D. have been treated思路分析：该题综合考查动词的时态和语态。句子的主语是patients，显然与tr

16、eat之间是动宾关系，应用被动语态。另外今年的情况和去年的情况相比，强调的是现在的结果，所以应该用现在完成时。答案：D5、Sales of CDs have greatly increased since the early 1990s，when people _to enjoy the advantages of this new technology.A. begin B. beganC. have began D. had began思路分析：该题中when引导的是一个非限制性定语从句，且when指代前面的the early 1990s ， 显然是过去的一个具体时间，所以用一般过去时态。

17、答案：B6、“You cant catch me！” Janet shouted， _ away.A. run B. running C. to run D. ran思路分析：该题考查非谓语动词。running away作伴随状语。答案：B7、They _on the program for almost one week before I joined them， and now we _it as no good results have come out so far .A .had been working； are still working B. had worked ； were

18、 still workingC. have been working； have worked D. have worked； are still working思路分析：该题考查动词的时态。由于题干提示before I joined them， 又有almost one week 表示叙述的是现在的情况，用现在进行时。答案：A8、I _along the street looking for a place to park when the accident _.A. went； was occurring B. went； occurredC. was going； occurred D.

19、 was going ；had occurred思路分析：前面的动作表示后面动作发生的背景。所以前面的动作用过去进行时，后面表示一个具体的动作，用一般过去时。答案：C9、Although medical science _control over several dangerous diseases， what worries us is that some of them are returning.A. achieve B. has achievedC. will achieve D. had achieved思路分析：该题考查动词的时态。从主句提供的参照时态一般现在时来看，从句表示已经取

20、得的成就，所以用现在完成时。答案：B10、It is said in the book that Thomas Edison (1847-1931)_the world lead-ing inventor for sixty years .A. would be B. has beenC. had been D. was思路分析：“60年来”在本题体现的是过去的概念，故用一般过去时。答案：D【模拟试题】(答题时间：30分钟)一. 单选1.
