It isn‘t raining now. 咱们出发吧。现在不下雨了。这类情况常与now现在,at the present现在,at the moment现在,today今天,this week这个星期,this year今年等时间状语连用。有时通过上下文可以判断出应采用何种时态,如: It's four o'clock in the afternoon.

(―读‖这一动作发生在过去,对现在造成的影响是:是否知道故事的内容。) I have bought two apples. 我买了两个苹果。 (―买‖这一动作发生在过去,对现在造成的结果是:拥有两个苹果。) 在学习这一概念的同时,还应注意常与现在完成时连用的几个副词:already,just,ever,yet,never等。already,just多用于肯定句中,ever,yet,never多用于疑问句和否定句中。如: I have already finished my homework.我已经做完家庭作业了。 He has just had his meal.他刚吃过饭。 Have you ever sung this English song?你曾唱过这首英文歌吗? They haven't started yet.他们还没有动身。 We have never heard of it.我们从来没有听说过这件事。 接触五:用法之二 :表示过去已经开始,一直持续到现在的动作或状态。 注:这一用法即现在完成进行时的用法 因为表示的是持续的动作或状态,所以使用的动词通常是延续性动词:be, stay, study, wait, keep, have… 等; 使用的时间状语通常由for或since 引导,但二者后接的词有所不同: for后常跟一个时间段,指某个动作到现在为止已持续了多长时间,如for three years, for half an hour等。since 作介词,后面可以接一个时间点,如since 1980,也可以接―一段时间+ago‖, 如: since three years ago, since two months ago等。 since 还可用作连词,引导一个过去时态的时间状语从句。 如:We have known each other since we went to college. 非延续性动词不能直接和for 或since 连用,但我们可以找一个相应的延续性动词或动词短语来替换这些非延续性动词,如: come→be, come to→be in / at, go out→ be out, leave→be away, begin / start→be on, stop→ be over,buy→ have, borrow→ keep, open→be open, close→be closed, join→be a member of, die→be dead, catch a cold→have a cold, get to know→know, become a teacher →be a teacher, fall asleep→be asleep, fall ill→ be ill等。 句型It is the first (second, third...) time that...的that从句中, 谓语动词须用现在完成时,表示到说话时为止动作发生过几次。如:It is the first time that I have been here. 接触六:现在完成时与一般过去时的用法比较 现在完成时表示过去的动作对现在造成的影响;一般过去时表示动作发生的时间在过去。试比较: The plane has arrived . 飞机已经来了。(说明现在的情况:飞机在这儿。) The plane arrived a quarter of an hour ago. 飞机是一刻钟以前抵达的。(强调动作发生的时间在过去。) 接触七:have been in, have been to 与have gone to 的用法 1. have(has) been in 意为―已经在某地呆了多长时间‖,常与表示一段时间的状语连用。如: Mr. Brown has been in Shanghai for three days. 布朗先生来上海已经有三天了。 They have been in Canada for five years. 他们到加拿大有五年了。 2. have(has) been to意为―曾经去过某地‖,表示现在已经不在那里了。 可与just, ever, never等连用。如: I've just been to the post office. 我刚才去邮局了。 Have you ever been to Hangzhou? 你曾经去过杭州吗? Mary has never been to the Great Wall. 玛丽从未去过长城。 3. have(has) been to 后面可接次数,表示去过某地几次。如: I've been to Beijing three times. 我去过北京三次。They have been to that village several times. 他们去过那个村庄好几次了。 4. have(has) gone to 意为―到某地去了‖,表示到了某地或正在去某地的途中。 总之,说话时该人不在现场,一般不用第一、第二人称代词作句子的主语。如: —Where is Tom? 汤姆在哪里? —He has gone to the bookshop.他到书店去了。 接触八:常用于现在完成时的时间状语 除了我们讲过的already, yet, still,just, ever, never, since短语和 for短语外,还有许多时间 状语常用于现在完成时,我们要留心将它们和一般过去时的时间状语区分开来: 1. lately, recently是完成时的时间状语;just now 有a moment ago 之意,是过去时的时间状语。如: Have you heard from your family lately/recently? Did you see Joan just now? 2. in the past few years 意思是―过去几年来‖,常用于完成时中; in the past意思是―在过去‖,常用于过去时中。 如: Great changes have taken place in my hometown in the past few years. Where did you work in the past? 3. ever since then与from then on / after that 都有―打那以后‖之意, 但前者常用于完成时,而后两者常用于过去时。如: She's lived here ever since then. I didn’t hear of Jim from then on/after that. 4. before 通常用于完成时;...ago通常用于过去时。如:I have never been to Japan before. She went to Japan two years ago. 5. so far―到目前为止‖, these days―这些天来‖也是现在完成时常见的时间状语。如:12\n So far, no man has travelled farther than the moon. What have you done these days? 接触八:过去分词有规则与不规则两种。 规则的变化形式与动词的过去式一样。不规则就需要记忆了 不规则动词过去式和过去分词 A. 原型:过去式和过去分词完全不同 drink--drank--drunk ;ring--rang---rung ;swim--swam--swum ;sing--sang--sung ;sink--sank--sunk; give--gave--given; hide--hid--hidden; do--did--done; see--saw--seen B. 过去式与过去分词完全相同bright--brought--brought think--thought----thought fight----fought--fought buy--bought--bought catch--caught--caught sell--sold--sold C.原型与过去分词相同 come--came--come; run--ran--run become--became--become D.原形与过去式和过去分词完全相同 cast--cast--cast cut--cut--cut put--put--put let--let--let set--set--set hit--hit--hit 【练习】 一、用所给动词的适当形式填空。 1.

He had been a good friend of mine. 史密斯先生昨天去世了。他以前是我的好友。 I didn’t know a thing about the verbs, for I had not studied my lesson. 我对动词一无所知,因为我没有好好学习功课。 12\n(4)在含有定语从句的主从复合句中,如果叙述的是过去的事,先发生的动作常用过去完成时。 I returned the book that I had borrowed. 我已归还了我借的书。 She found the key that she had lost. 她丢失的钥匙找到了。 (5)过去完成时常常用在told,said,knew,heard,thought等动词后的宾语从句(或间接引语)中,这时从句中的动作发生在主句表示的过去的动作之前。 He said that he had known her well. 他说他很熟悉她。 I thought I had sent the letter a week before. 我认为我一星期前就把信寄出去了。 (6) 状语从句:在过去不同时间发生的两个动作中,发生在前,用过去完成时;发生在后,用一般过去时。 如when,before,after,as soon as,till/until引导的 When I woke up, it had already stopped raining. 我醒来时雨已停了。 She didn’t go to bed until she had finished her work. 她直到把工作做完之后才睡觉。 注意:如果两个动作紧接着发生,则常常不用过去完成时,特别是在包含before和after的复合句中,因为 这 时从句的动作和主句的动作发生的先后顺序已经非常明确,这时可以用一般过去时代替过去完成时。 After he arrived in England, Marx worked hard to improve his English. 马克思到达英格兰之后,努力提高他的英语水平。 (7)动词think, want, hope, mean, plan, intend等用过去完成时来表示过去未曾实现的想法,打算或意图等。 They had wanted to help but could not get there in time. 他们本来打算去帮忙,但没有及时赶到那里。 We had hoped to be able to come and see you . 我们本来希望能来看看你。 (8)过去完成时还可用在hardly…when…, no sooner…than…, It was the first (second, etc) time (that)…等固定句型中。 Hardly had he begun to speak when the audience interrupted him. 他刚开始演讲,听众就打断了他。 No sooner had he arrived than he went away again. 他刚到就又走了。 It was the third time that he had been out of work that year. 这是他那一年第三次失业了。 语法判定 1. 由时间状语来判定 :一般说来,各种时态都有特定的时间状语。与过去完成时连用的时间状语有: (1)by + 过去的时间点。如: I had finished reading the novel by nine o'clock last night. (2)by the end of + 过去的时间点。如:We had learned over two thousand English words by the end of last term. (3)before + 过去的时间点。如: They had planted six hundred trees before last Wednesday. 2. 由―过去的过去‖来判定:过去完成时表示―过去的过去‖,是指过去某一动作之前已经发生或完成的动作,即动作有先后关系,动作在前的用过去完成时,在后的用一般过去时。这种用法常出现在: ( 1 )宾语从句中 :当宾语从句的主句为一般过去时,且从句的动作先于主句的动作时,从句要用过去完成时。在told, said, knew, heard, thought等动词后的宾语从句。如: She said that she had seen the film before. ( 2 )状语从句中 :在时间、条件、原因、方式等状语从句中,主、从句的动作发生有先后关系,动作在前的,要用过去完成时,动作在后的要用一般过去时。如: After he had finished his homework, he went to bed. 注意: before, after 引导的时间状语从句中,由于 before 和 after 本身已表达了动作的先后关系,若主、从句表示的动作紧密相连,则主、从句都用一般过去时。如: After he closed the door, he left the classroom. (3)表示意向的动词,如hope, wish, expect, think, intend, mean, suppose等,用过去完成时表示"原本…,未能…" We had hoped that you would come, but you didn't. 3. 根据上、下文来判定。 I met Wang Tao in the street yesterday.

I will live on a space station in the future. →Where will you live in the future? 用法 1)will可用于所有人称,但shall 仅表示单纯将来时,用于第一人称I和we,作为will的一种替代形式。以You and I为主语时通常避免用shall. 例如: He will be back soon. 他很快就会回来。 I shall/will be free on Sunday. 星期天我有空。 You and I will work in the same factory. 你和我将在同一工厂工作。 2)will,shall可用来预言将来发生的事。如说出我们设想会发生的事,或者请对方预言将要发生什么事。例如: It will rain tomorrow. 明天将要下雨。 3)will,shall除可表示单纯的将来时以外,还可以带有意愿的色彩,仍指的是将来。例如:I'll buy you a bicycle for your birthday. 你过生日时,我给你买一辆自行车。(表示允诺) Will you open the door for me please?请你帮我开门好吗?(表示请求) Shall I get your coat for you? 12\n我可以为你拿外套吗?(表示提议) 2.be going to +V原形+其它.(表示近期的打算或计划将要发生的事) (1)肯定句:主语+ be going to +V原形+其它.
