据专家权威分析,试题“I _________ him before. But my friends _________ him two da..”主要考查你对 现在完成时,一般过去时 等考点的理解。关于这些考点的“档案”如下:
现在完成时一般过去时
考点名称:现在完成时
现在完成时: 过去发生并且已经完成的动作对现在造成影响或后果,过去某一时间开始并一直持续到现在的动作或状态。 基本结构:主语+have/has+动词的过去分词 句式: 1. 否定句式:现在完成时的否定句式是“haven't (hasn't)+过去分词...”。 如:I have not seen the movie yet. 我还没看这部电影。 2. 一般疑问句:Have(Has)+主语+过去分词...? 如: —Have you finished the work?你已经做完这项工作了吗? —Yes, I have. 是的,我已经做完了。(No, I haven't. 不,我还没有做完。) 3. 特殊疑问句:特殊疑问词+have(has)+主语+过去分词...?如: How many times have you been to the Great Wall?你去过长城几次? 提示:肯定句中有some, already时,改为否定句或疑问句时通常要分别改为any, yet。如: I have already finished my homework. 我已经完成了我的作业。 → I haven't finished my homework yet. (否定句) → Have you finished your homework yet? (一般疑问句) 现在完成时常见两种句型: ①for短语 ②It is+一段时间+ since从句
现在完成时特点: 1. 非持续性动词的完成时的肯定式不能与时间段连用,若要用时间段状语,则应换成相应的持续性动词或状态动词。 例如: He has left. He has been away for an hour. 2. have/has been to 表示曾经去过某地,但现在不在那;have/has gone to表示现在已去某地,现在不在这。 例如: He has been to Canada, but now he is working in our company. Mr. Li in not at home. He has gone to Shanghai. 3. 完成时的肯定式常用already,而否定式和疑问式常用yet,但若already用于疑问句时,表示一种出乎意外的惊讶。 例如:Have you read it already?
现在完成时和一般过去时区别: 现在完成时和一般过去时都表示在过去完成的动作。 但现在完成时强调的是这一动作与现在的关系。如对现在产生的结果或影响等, 而一般过去时只表示动作在过去某一时刻发生,不表示和现在的关系。 比较: I have lost my new book. 我把新书丢了。(现在还未找到) I lost my new book yesterday. 我昨天把新书丢了。(昨天丢的,现在找到与否没说明)
have been(to)与have gone( to)的区别: have been(to)表示“去过某地(现在已经回来了)”,可用于各人称; have gone(to)表示“去某地了(说话时某人不在当地)”,常用于第三人称, 前者可与once ,never,several times等连用,后者则不能。 如: They have been to Beijing twice.他们去过北京两次。 He has gone to Beijing . 他去北京了。 现在完成时注意事项: 1.如单纯表示一段时间,或强调一段时间,虽有since一词,也不必用完成时。如: It is two years since his father died. =His father has been dead for two years.他父亲去世已有三年了。
2.终止性动词现在完成时的否定式,已变成一种可以延续的状态,因此可以和表示一段时间的状语连用。如: I haven't left here since 1997.自从1997年以来,我一直没有离开过这儿。
现在完成时的用法: 1.表示动作发生在过去某个不确定的时间,但对现在留下了某种影响和结果。常被just、already、yet 等副词修饰。如: -Have you had lunch yet? -Yes,I have. I've just had it. 2.表示从过去某一时刻开始一直持续到现在的动作或状态。这个动作可能刚停止,可能仍然在进行。 常带有for和since等表示一段时间的状语。如: He has taught here since 1981 他自1981年就在这儿教书。(可能还要继续教) I have't seen her for four years. 我有四年没见到她了。 3.表示说话前发生过一次或多次的动作,现在成为一种经验,一般译为汉语“过”。 常与twice,ever,never,three times等时间状语。 如: I have been to Beijing twice.我去过北京
4. 现在完成时还往往可以同包括现在时间在内的时间状语连用,如: now,up to these few days/weeks/months/years,this morning/week/month/year,just,today,up to present,so far等: Peter has written six papers so far. Man has now learned to release energy from the nucleus of the atom. There has been too much rain in San Francisco this year. The friendly relations and cooperation between our two countries have been enhanced in the past few years. Up to the present everything has been successful.
5.现在完成时往往同表示不确定的过去时间状语连用,如: already(肯定),yet(否定,疑问),just,before,recently,still,lately,never等: He has already obtained a scholarship. I haven't seen much of him recently (lately). We have seen that film before. Have they found the missing child yet?
6.现在完成时的"完成用法" 现在完成时的"完成用法"指的是动作发生在过去某一时刻并已结束,但该动作对现在产生了影响,与现在情况具有因果关系。 例如: He has turned off the light.他已把灯关了。(动作结束于过去,但说明的是现在的情况--灯现在不亮了。) 现在完成时"完成用法"的特点是动作不延续,因此: 该时态只能与表示不定的过去时间状语(如:already,yet,before,recently等)、频度时间状语(如:never,ever,once等)、包括现在时刻在内的时间状语(如:this morning / month /year...,today等)连用。 例如:Have you found your pen yet?你已找到你的钢笔了吗? 7.现在完成时的"未完成用法" 现在完成时的"未完成用法"指的是动作开始于过去某一时刻,一直延续到现在,或可能还要继续下去。 例如: He has lived here since 1978.自从1978年以来,他一直住在这儿。 (动作起始于1978年,一直住到现在,可能还要继续住下去。) I have been in the army for more than 5 years.我在部队已经呆了五年多了。 (动作开始于5年前,一直延续至今,有可能还要继续下去。) 此种用法的句中常需一个表示一段时间的状语(由since或for引导),或表示与现在时刻相连的时间状语(如:up to now,so far)等。 例如: I have heard nothing from him up to now.到目前为止我没有他的任何消息。 注意:现在完成时的未完成用法只适用于延续性动词,不可用于终止性动词,即瞬间完成或延续时间很短的动词。 如:come,go,arrive,leave,join,become,die等。 8.一段时间+has passed+since从句 主语+have / has been+since短语 例如:He has been in the League for three years. 或It is three years since he joined the League. 他入团已三年了 9. 现在完成时常和短语 "up to now /till now","so far" (意思是从过去某一确定的时间一直延续到现在)连用。 Up to/till now he's read many story books. 至今他已读过好多故事书。 I've been to New York three times so far. 至今我已到纽约去过三次。 has gone (to),has been (to),has been (in) 的区别 has gone to:去了没回 has been to :去过 has been in:呆了很久
一般过去时句法结构: 肯定形式 主语+动词过去式+其他 例句:She often came to help us in those days. 否定形式 ①was/were+not;②在行为动词前加didn't,同时还原行为动词 例句:I didn't know you like coffee 一般疑问句 ①Did+主语+do+其他? ②Was\Were+主语+表语? 例句:Did I do that? 用表格整理如下:
结构句型: 1.一般句子 I watched TV last night. 2.一般疑问句 Did you watch TV last night? 3.there be 句型 There was an apple on the table last night. Was there an apple on the table last night
一般过去时注意事项: 1.注意主句与从句中时态的一致性 如果主句用了过去时,从句中一般也要用过去式,或者过去进行时、过去完成时等。例如: He believed that he was right. 他相信自己是对的。 I didn’t know you were here. 我不知道你在这儿。 I thought they were with you. 我以为他们和你在一起。
2.在口语中, 一般过去时并不一定指真正的过去,而只是表示一种礼貌性语气。例如: I wondered (wonder) if you could do me a favor. 不知你可否帮我一个忙。 I wanted (want) to ask if I could borrow your car. 我想问问可否借用你的车。 I hoped (hope) you could (can) give me some advice. 我希望你能帮我出点主意。 Did (Do) you want to see me? 你想见我吗?
3.used to used to 是一个词组,表示“过去曾经是……而现在已经停止了”的动作。例如: I used to work fourteen hours a day. 我过去常常一天干十四个小时。(而现在不这样了) I used to take a walk in the morning.我过去是在早晨散步。(而现在不在早晨散步了)
一般过去式用法: (1)一般过去时表示在过去某个特定时间发生,也可以表示过去习惯性、经常性的动作。 一般过去时不强调动作对现在的影响,只说明过去的事情。 句式:主语+动词过去式+宾语+其它 I had a word with Julia this morning.今天早晨,我跟茱莉雅说了几句话。 He smoked many cigarettes a day until he gave up. 他没有戒烟的那阵子,抽烟抽得可凶了。
(2) 一般过去时常与表示过去的时间状语或从句连用,如: yesterday,last week ,in the past ,in 1993,at that time,once,during the war,before,a few days ago,when 等等. (句子中谓语动词是用一般过去时还是用现在完成时,取决于动作是否对现在有影响)。 Have you had your lunch? 你吃过午饭了吗?(你现在不饿吗?) Yes,I have. 是的,我已经吃过了。(已经吃饱了,不想再吃了。) When did you have it? 你是什么时候吃的?(关心的是吃的动作发生在何时。) I had it about ten minutes ago. 我大约是十分钟以前吃的。) Used to do something 表示过去常做而现在已经停止了的习惯动作。 I used to work fourteen hours a day. 我过去常常一天干十四个小时。 I ate it at 6:45。我在六点四十五分吃了。
(3)带有确定的过去时间状语时,要用过去时。如: yesterday(昨天)、two days ago…(两天前…… )、last year…(去年…)、the other day(前几天)、 once upon a time(很久以前)、 just now(刚才)、in the old days(过去的日子里)、before liberation(解放前…)、 When I was 8 years old(当我八岁时…)、at+一个时间点 Did you have a party the other day?前几天,你们开了晚会了吗? Lei Feng was a good soldier.雷锋是个好战士。 注:在谈到已死去的人的情况时,多用过去时。
(4)表示过去连续发生的动作时,要用过去时。这种情况下,往往没有表示过去的时间状语,而通过上下文来表示。 The boy opened his eyes for a moment,looked at the captain,and then died. 那男孩把眼睛张开了一会儿,看看船长,然后就去世了。
(5)表示过去一段时间内经常或反复的动作。常与always,never等连用。 Mrs. Peter always carried an umbrella.彼得太太过去老是带着一把伞。 (只是说明她过去的动作,不表明她现在是否常带着伞。) 比较: Mrs. Peter always carries an umbrella.彼得太太老是带着伞。 (说明这是她的习惯,表明她现在仍然还习惯总带着一把伞) Mrs. Peter is always carrying an umbrella.彼得太太 总是带着一把伞。 (表示说话者对这一动作或行为厌烦) I never drank wine.我以前从不喝酒。 (不涉及到现在,不说明现在是否喝酒)
(6)如果强调已经终止的习惯时要用 used to do(过去常常做,而现在不那样做了) He used to drink alcohol.他过去喝酒。 (意味着他现在不喝酒了。喝酒这个动作终止了) I used to take a walk in the morning.我过去是在早晨散步。 (意味着现在不在早晨散步了) 比较: I took a walk in the morning.我曾经在早晨散过步。 (只是说明过去这一动作)
(7)有些句子,虽然没有表示过去确定时间的状语,但实际上是指过去发生的动作或存在的状态的话,也要用过去时。 I didn''t know you were in Paris.我不知道你在巴黎。 (因为在说话时,我已经知道你在巴黎了。这句话指的是说话之前,所以只能用过去时表示。实际上,这句话暗指:But now I know you are here.) I thought you were ill.我以为你病了呢。 (这句话应是在说话之前,我以为你病了。但是现在我知道你没病)
一般过去时三变技巧: 一变:肯定句变为否定句 技巧1.当句中含有情态动词或助动词could,would,should等时,可直接在其后面加not构成否定句。例如: I could get you a concert ticket. → I could not / couldn't get you a concert ticket. 技巧2.当句中含有系动词was,were 时,可直接在其后加not构成否定句。例如: I was on the Internet when you called me. → I was not / wasn't on the Internet when you called me. 技巧3.当句中谓语是除情态动词、助动词、系动词was, were以外的动词时,在该动词之前加did not / didn't,动词还原,构成否定句。例如: The famous singer sang some Chinese songs. → The famous singer did not / didn't sing any Chinese songs.
二变:陈述句变为一般疑问句 技巧1.移动词语的位置。将was,were, could,would,should等移到句首。例如: He could pack his things himself. → Could he pack his things himself? 技巧2.添加助动词did。谓语是除情态动词、助动词、系动词was, were以外的动词时,在主语之前加did,动词还原。例如: Mr Li looked very old. → Did Mr Li look very old?
三变:陈述句变为特殊疑问句 技巧1.确定疑问词:人who / whom,物what,地点where,时间when / what time,原因why,频率how often,长度how long,距离how far等等。例如: They gave the concert last night. → When did they give the concert? 技巧2.辨认结构形式:疑问词+情态动词/助动词/ was / were / did +主语+...? 例如: The accident happened near the station. → Where did the accident happen?
