2.一般过去时.doc

一一般过去时编辑本段一般过去式The past Indefinite tense1.概念：过去某个时间里发生的动作或状态；过去习惯性、经常性的动作、行为；2.时间状语：ago, yesterday, the day before yesterday, last week,last(year, night, month), in 1989, just now, at the age of 5, one day, long ago, once upon a time(很久以前), etc. 3.基本结构：be动词；行为动词 的过去式4.否定形式：was/were+not;在行为动词前加didnt，同时还原行为动词。 5.一般疑问句：was或were放于句首；用助动词do的过去式did 提问，同时还原行为动词。 6.例句：She often came to help us in those days. I didnt know you were so busy.一般过去时表示(1)过去某个特定时间发生，也可以表示(2)过去习惯性的动作。一般过去时不强调动作对现在的影响，只说明过去。 句式：主语+过去动词+其他I had a word with Julia this morning.今天早晨，我跟朱丽亚说了几句话。(1) 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 1993, at that time, once, during the war, before, a few days ago, when 等等。 补充内容：（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。一般过去时的基本用法 1 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。注意在谈到已死去的人的情况时，多用过去时。2 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。3 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）4 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.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）5 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，这一点，我们中国学生往往出错，要特别注意！I didnt 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）辨别正误Li Ming studied English this morning.（把此句变为一般疑问句）（）1.Did Li Ming studied English this morning？（动词应该用原形）（） 2. Does Li ming Study English this morning？（时态应该用原句子的时态）（） 3.Was Li Ming studied English this morning？（应该用一般动词，而不是be动词）（） 4.Did Li Ming study Enghish this morning？ 一过：在过去发生的动作。主动：肯定 be 分为was,were v+ed否定 was/were not didnt+v疑问 was/were+ 主 did+主+V时间状语1. yesterday (morning,afternoon,evening)2. the day before yesterday3. last night (week,Sunday,weekend,month,winter,year,centeury 世纪）4. ago 5.in 1980 (过去年份）6.this morning/afternoon/evening7.when引导的状语从句 （过去）8.in the past9.just now10.the other day - a few days ago11.at the age of 10 (过去年龄段）12.in the old days. 动词过去式规则变化1 直接加ed eg：work worked worked2 以不发音的e结尾的，+d eg：live lived lived3 以辅音字母+y结尾的，变y为i加ed eg：study stuied stuied4 以重读闭音节结尾的，双写最后的辅音字母+ed eg： stop stopped stopped 不规则变化例如相等 eg：cut cut read read sit sat句型结构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?一般过去时口诀一般过去时并不难，表示过去动作、状态记心间。动词要用过去式，时间状语句末站。否定句很简单，didnt 站在动词原形前，其它部分不要变。一般疑问句也好变，did放在句子前，主语、动词原形、其它部分依次站。特殊疑问句也简单，疑问词加一般疑问句记心间。最后一条请注意，动词过去式要牢记。二一般过去时一般过去时主要表示过去某时发生的动作或情况。可以从以下几个方面来理解：1）过去某个时间所发生的动作或存在的状态。e.g. I bought a new shirt yesterday. He was a worker two years ago.2）过去一段时间内，经常性或习惯性的动作。e.g. When I was a child,I often played with fire. Li Lei always walked to school last term.3）谈到已故人的情况时多用过去时。e.g. Lu Xun was a great writer.4）有些发生时间不是很清楚的情况，实际是过去发生的，也应用过去时态。e.g. What did you say? 另外，e.g. Could you lend me your pen?表委婉语气.Could you tell me where you have been? 其结构是主语+动词的过去式。be动词的过去式为was, were；行为动词的过去式有规则变化和不规则变化两种，规则变化有以下几种情况：1）直接在动词原形末尾加-ed. e.g. work-worked; ask-asked; 2）以e结尾的动词只加-d. e.g. arrive-arrived; like-liked.3)末尾只有一个辅音字母的重读闭音节,应先双写这个辅音字母,再加-ed. e.g. shop-shopped; stop-stopped,plan-planned; 4)以辅音字母+y结尾的动词,先把y变成i,再加-ed. e.g. carry-carried; study-studied.有些动词变过去式是不规则的见表要牢记,e.g. fly-flew; break-broke; teach-taught. 这些需要象生单词一样记住. 其句式变化分为两种情况1)含有be动词的依然在be上做文章. e.g. I was born in 1980. I was not born in 1980. Were you born in 1980? 2)含有行为动词的变否定句要在行为动词前加助动词didnt.,同时把动词变成原形; 变一般疑问句,在句首加助动词did,同时把动词变成原形. e.g. I bought a gift for my mum yesterday. I didnt buy a gift for my mum yesterday. Did you buy a gift for your mum yesterday?其时间状语为yesterday或由其构成的短语,e.g. yesterday morning; 由last+时间构成的短语, e.g. last year; 由时间段+ago构成的短语, e.g. three days ago; 另外,还有on the morning of Monday, just now等,以及一些表示过去时态的从句.注意,在宾语从句中主句为过去,一般从句也为过去. 常见错误如下: 一把动词变成过去式易出错 例: 1 They stoped (stop) talking just now. 2 They plaied (play) football yesterday. 答案: 1 stopped 2 played 解析:我们可以记住下面的口诀:动词变成过去式,双写规律要牢记;y前若是辅音字,y变i加-ed;y前若是元音字,只须直接加-ed. 二忘记把动词变成过去式 例: I fly (fly) kites on the afternoon of Sunday. 答案: flew 解析:我们可以记住下面的口诀:一般过去时态里,过去形式莫忘记.自主检测:（一 ）选择1 She lived there before he_to China.
