When While用法归纳1) 一种状态/地点+ when +what happened (短暂性动词) I was surprised when my father shouted.I was in the bathroom when the rainstorm came. 2) what was happening + when + what happenedI was waiting for the bus when it began to rain heavily. 同义句 While I was waiting for the bus,it began to rain heavily. 3) While what was happening, + what happened (短暂性动词) While you were sleeping, I called Jenny. 同义句You were sleeping when I called Jenny.4) While what was happening, + what was happening While I was doing my homework, my father was reading a newspaper.以when和while引导的时间状语从句1) 延续性动词和非延续性动词延续性动词指动作可以延续一段时间, 而不是 瞬间结束。如: work、study、drink、eat等。非延续性动词指动作极为短暂，瞬间结束。如: start、begin、hit、jump、knock等。2) 在本单元中, 出现了以when和while引导的 时间状语从句。when表示“当的时候”。从句中既可用延续性动词, 又可用非延续性动词, 这些动词既可以表示动作, 又可表示状态。从句中的动作既可和主句的动作同时发生, 又可在主句的动作之前或之后发生。如：Mary was having dinner when I saw her .The boy was still sleeping when his mother got home yesterday morning .while表示“在的时候”、“在期间”。它强调主句的动作与从句的动作同时发生或主句的动作发生在从句的动作过程中。While从句中必须是表示动作或状态的延续性动词。如：The weather was fine while we were in Beijing .She called while I was out.如果主句的动作在从句的动作过程中发生，从句常用进行时。如:While we were swimming someone stole our clothes .Dont talk so loud while others are working.总结1) when可指时间点, 又可指时间段, 从句中 可用延续性动词, 也可用非延续性动词。2) while总是指一个时间段, 从句中必须用延 续性动词。1. _ Jennifer was reading a magazine, his sister was listening to the pop music.A. WhileB. When C. What time2. I was trying to draw a cat on the board _ the teacher came in.A. whileB. when C. what time3.

I was writing a letter to my father at that moment.b: 表示过去某段时间内正进行的动作。e.g. We were building a house last winter. They were waiting for you yesterday.否定句和疑问句：e.g. We were not sleeping at home. Was he feeling well?过去进行时和一般过去时的区别1) 过去进行时表示过去正在进行的动作, 而一般过去时则表示一个完整的动作。如：They were writing letters to their friends last night.昨晚他们在写信给他们的朋友。(没有说明信是否写完)They wrote letters to their friends last night .他们昨晚写了信给他们的朋友。(表达了他们已写好的意思, 整个写的过程已完成)2) 当动作延续较长时间时或表示厌烦、赞美等感情色彩时, 常用过去进行时表示。如：He was thinking more of others than of himself.他考虑别人的比考虑自己的多。(表示说话者赞扬的口气)The boy was always making trouble then .那时, 他总是惹麻烦。(表示说话者厌烦的口气)1. Sally took a photo of her friends while they _ computer games. 2013浙江杭州 A. play B. are playing C. have playedD. were playing2. Just a minute!

What _ (be) you _ (do) when he arrived?2. Jim _ (sleep) when I came in.3.They _ (watch) TV at 8:00 yesterday evening.3. Now he _ (read) and _(write). 一、 现在完成时的主要用法1.表示过去发生的某一动作对现在造成的影响和结果。He has just turned off the light. 他刚把灯关了。相当于：He turned off the light just now. The light isnt on now. 即关灯这一动作对现在造成的结果和影响：现在灯不亮了。 I have already finished my homework.我已经完成了家庭作业。2.表示过去已经开始，持续到现在的动作或状态，也可以表示实质可能继续下去的动作或状态。这时往往与表示一段的时间状语连用。She has lived here since she was born.自从她出生时就一直住在这儿。I have learnt English for more than ten years.我已经学了10多年的英语。二、现在完成时的构成：助动词have (has）+ 动词过去分词三、现在完成时的时间状语一个时间点时间状语从句一段时间ago1、sinceMr. Smith has worked here since 1984.I have known Tom since 7 years ago.Hes learned about 500 words since he went to college.2、for一段时间（two weeks/six months/five days）for短语表示动作延续长时间 。 He has taught in this school for four years. 我们认识有二十年了。 I havent seen her for a long time. 我好久没有见到她了。3、just, already, ever， recently，before, never是完成时态的时间状语，而just now /a moment ago 是一般过去时的时间状语。The train has just arrived. （火车刚到。）Did you see Joan just now? （你刚才看到琼了吗？）Have you heard from your family recently? （你最近收到家人的来信了吗？）二、过去分词的构成类型原形 过去式过去分词AAAcostcostcostreadreadreadABBmeetmetmetcatchcaughtcaught ABCrideroderiddenspeakspokespokenkeepkeptkeptdrinkdrankdrunkeatateeaten五、瞬间动词动词与时间段的关系瞬间动词也叫短暂性动词或终止性动词。这种动词是指它们动作的开始也就意味着动作的结束，所以在肯定句、疑问句中不能与表示一段时间的时间状语连用（在否定句可以用，表示一种状态）但可以用其它方式来表示。I havent bought the bike for a year. 我买这辆自行车还不到一年。为了表述这种意思，我们常用相应的延续性动词have，keep或短语“be+名词（形容词、位置副词、介词短语）”来代替短暂性动词， ”来代替短暂性动词.borrowkeep； buyhave; get to knowknow;become be; beginbe on;finishbe over; diebe dead; fall asleepbe asleep; fall ill be ill; leave be away (from), come(go, arrive, get) be here/there/in; joinbe in （be a member of ）, 也可以仍用原短暂性动词，用句型“It is since从句（从句中用一般过去时）”或用“一般过去时+ ago”这一结构来表述延续性的动作或状 态。 for和since引导的 时间状语不能与终止性动词的肯定式连用，但可和其否定式连用。 1.电影开始五分钟了。 The film has been on for five minutes. It is five minutes since the film began The film began five minutes ago. 2.他入党五年了。 He has been in the Party for five years. It is five years since he joined the Party. He joined the Party five years ago .3.我买了这块手表五年了。I bought this watch five years ago. I have had this watch for five years/since 5 years ago. 4.这位老人已经死了十年了。The old man died ten years ago. The old man has been dead for ten years/since 10 years ago.5.他已经回来三天了。He has come back for 3 days.He has been back for 3 days/since 3 days ago. 6.我离开家乡已十年了。 I have left hometown for 10 years. I have been away from hometown for 10 years.六、have been to与have gone tohave been to 意思是“到过，去过”，表示曾经到过某处，但现在人不在那儿。 Has she ever been to Nanjing?她曾经去过南京吗？have gone to 意思是“去了”，表示已经去了某地，现在人可能在去的途中或已在那儿了。-Where is she?-She has gone to Nanjing. 她已经去南京了。七、与一般过去时的用法比较1.一般过去时表示过去发生的动作或单纯叙述过去的事情，强调动作发生在过去，和现在没有关系，而现在完成时是表过去发生的某一动作对现在造成的影响或结果，强调的是现在的情况。 2.一般过去时常与具体的时间状语连用，现在完成时通常与模糊的时间状语连用，或无时间状语。1.一般过去时的时间状语有: yesterday ,last week,一段时间ago, in 1980（过去时间）, in October ,just now, a moment ago. eg: The plane took off ten minutes ago. We finished our task last week .2.现在完成时的时间状语：for, since, ever, just, yet, already等不确定的时间状语。They have lived here for ten years.She has been in the Reading Club for many years .I have known Daniel since ten years ago. He has bought an English-Chinese dictionary. 他已经买了一本英汉字典。 He bought an English-Chinese dictionary. 他曾买过一本英汉字典。H第一句用现在完成时时态，意为：“He bought an English-Chinese dictionary. And he still has it” “过去他买了一本英汉字典，现在他还有这本字典” 。H第二句用过去时只叙述过去他买过一本英汉字典这一事实，至于现在他是否有这本字典并未强 调说明。动 词 填 空： 1._ you already_ (clean) the room? Yes, we _(do) that already. When _ you _(do) it?
