4、表示包括现在时间在内的状语。不能和表示过去的时间状语连用（如：in 1990，last Sunday 等）。例如： He has studied English for 5 years. He has studied English since 2001. Now I have finished the work.注意：表过去某一时间发生的动作或状态一直延续到现在（强调现在），动作或状态一般是延续性的，因此要用表延续性的动词或表状态的动词。表示短暂时间动作的词，如:come，go，die，marry，buy等的完成时不能与for，since等表示一段时间的词连用。也不能用于how long引导

5、的疑问句中。如不能说：He has borrowed the book for two months.()但可以说：He has kept the book for 2 months.或：It has been 2 months since he borrowed the book. 或：Two months has passed since he borrowed the book. 这些瞬间动词常与它对应的可以表示时间段的词语进行互换。becomebe borrowkeep buyhave begin (start)be on openbe open diebe dead leave-be

6、 away come-be here/in go outbe outjoin-be a member/be in begin to study-study注明：非延续性动词在否定结构中可用于现在完成时态：I havent bought anything for two days.2、现在完成时的结构：have / has + 过去分词 否定结构：havent / hasnt + 过去分词 一般疑问句中：Have/Has+主语+动词的过去分词3、一般过去时：一般过去时只表示过去的动作或状态，和现在不发生关系（即动作或状态在现在已经结束），它可以和表示过去的时间状语连用。现在完成时与一般过去时的区

7、别：现在完成时用来表示之前已发生或完成的动作或状态，其结果的确和现在有联系。动作或状态发生在过去，但它的影响现在还存在；而一般过去时表示过去的事实，不表示和现在的关系。I have just been to London. I went there last month. 我刚去过伦敦，是上个月去的。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；现在完成时为过去发生的，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,

8、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，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

9、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 yesterday. （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 retu

10、rned yesterday. 她是昨天回来了。 He has been in the League for three years. (在团内的状态可延续) He has been a League member 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。) I have finished my homework now. -Will somebody go and get Dr. White? -Hes already been sent for.句子中如有过

11、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.二、动词的过去分词的规则变化1 、规则动词：规则动词的过去分词的构成规则与规则动词的过去式的构成规则相同。四点变化规则： (1）、一般动词，在词尾直接加“ ed ”。 work-worked-worked,visit-visited-visited (2）、以“ e ”结尾

12、的动词，只在词尾加“ d ”。 live-lived-lived, (3）、以“辅音字母 + y ”结尾的动词，将 y 变为 i ，再加“ ed ”。 study-studied-studied,cry-cried-cried (4）、重读闭音节结尾，末尾只有一个辅音字母，先双写该辅音字母，再加“ ed ”。 stop-stopped-stopped,drop-dropped-dropped2、不规则动词的过去式以及过去分词巧记规律：AAA：cost-cost-cost read-read-readput-put-put cut-cut-cutlet-let-let set-set-setbe

13、at-beat-beat hit-hit-hit hurt-hurt-hurt spit-spit-spit rid-rid-rid注：原形、过去式和过去分词的词形和读音都相同的单词，结尾字母一般是t或d。特殊：动词read的过去式和过去分词虽然词形与原形一致，read-read-read，但发音分别是ri:d-red-red。 ABA（含规则动词）：有些动词的过去分词与原形是一样的:run-ran-run come-came-come become-became-become overcome-overcame-overcomeABB（含规则动词）：1.另有一些其它形式的变化。have (h

14、as)-had-had leave-left-leftlose-lost-lost make-made-madefeel-felt-felt spell-spelt-spelt stand-stood-stood2. 改变单词中间元音字母。sit-sat-sat (babysit) win-won-wonshine-shone-shone hold-held-heldfind-found-found hear-heard-heardhang-hung (hanged)-hung (hanged)ABC：有些动词的过去分词是在原形词尾加n或en，变成以en结尾的单词。 take-took-tak

15、en give-gave-givenfall-fell-fallen eat-ate-eatenwrite-wrote-written speak-spoke-spokenfreeze-froze-frozen ride-rode-ridden get-got-gotten (got) forget-forgot-forgotten (forgot)特殊： am/is-was-been are-were-been,do (does)-did-done go-went-gonesee-saw-seen show-showed-shown (showed) lie-lay (lied)-lain

16、(lied) 三、重难点词汇精讲1. Have you ever been to an amusement park? have been to .have been to + 地点：去过某地（已回）have been to表示“到(去)过某处”，现在已不在那个地方。 如：He has been to England 他曾到过英国。(现在已经不在英国了) Have you ever been to the Great Wall？ 你到过长城吗?（现在已经不在长城上） have gone to + 地点：去了某地（未回）have gone to表示“去了某处”，“到某处去了”，现在已不在说话的地

17、点了。 如：He has gone to England。 他已去英国了。(已经不在说话的地方，到达英国或者在去英国的路上) 2、 ever, never, already, yet, still1) ever常用于否定句、疑问句中。v ever常用于现在完成时中。v ever用于强化比较级和最高级。 Whats the best gift you have ever received?v ever since：自那时起The shop has been open ever since.forever：永远的（地）2） never：从不 -Have you ever been to an am

18、usement park? -No, never. already：已经（肯）- yet：已经，还（否、疑） He has already been to Beijing twice. He hasnt been to Beijing yet. -Have you been to Beijing yet? -No, not yet. still：仍然，还；常用于肯定句中3、neither (1) Neither Jenny nor I own a car. (2) Leon neither drinks nor smokes. (3) My husband doesnt want to see

19、 a movie tonight, and neither do I. (4) A: Which of the dresses did you like? B: Neither of them. (5) A: I havent seen that movie. B: I havent ，either. ( Neither have I. ) ( Me, neither )形容词，意为“两者都不”，置于单数名词前Neither girl has been there before. - 两个女孩以前都没去过那。代词，意为“两者都不，双方均不”。Neither of the girls has b

20、een there before.I like neither. -连词， 常用短语：neither . nor .表示“既不 .，也不.。”Neither he nor I _ interested in it. (be) - _原则I will believe neither you nor _. (he)副词，作“也不”，放在句首，表示前面否定的内容也适用于后面的人或物， 形容词或副词提前，需用倒装句。注意：neither作主语时，通常被视为单数，但有复数意义。v neither. nor .；either . or .；not only ., but also .连接两个并列结构,句型

21、中使用就近原则，both . and .句型中，谓语动词用复数形式。-I dont like this dress.-Neither do I. - 我也不喜欢。(I dont like this dress, either) I havent been to an amusement park.Me, neither.(对应：Me, too.) =I havent been to an amusement park, either.(not. either = neither) =Neither have I.If you cant solve it, neither can he. (He

22、 cant solve it, either.)I am not interested in it, neither is he. (He is not interested in it, either.)练：If you dont help me, neither _ others. 4、neither, nor, so引导的倒装句：1) 句式：v Neither/Nor/So + 助动词/be动词/情态动词 + 主语. 表示“.也/也不”。Neither do I. = Nor do I. -我也不。So do I. -我也是。v So + 主语 + 助动词/be动词/情态动词. 表“确实

23、如此”，用于同意上文中的对方的观点。- It is a nice day.- So it is. -它确实是个好天气。三、综合练习一、单项选择1、 He_ to Canada, so you cant see him recently.A have been to B have gone to C has been to D has gone to2、I have been to America, so_ he.A did B have C has D does3、London has ever hosted the modern Olympics Paris .A.
