Ill do it better if I_ （give） five more minutes.2. The teacher told us that light_ （travel） faster than sound.3. She_ （put） on her coat and went out.三、现在进行时概念现在进行时表示现在或目前一段时间内正在进行或发生的动作。构成主语+be（am/is/are）+动词的现在分词+其他。时间状语1. 常用的时间状语及提示性动词有now, at the moment, these days, look, listen等。2. 没有进行时的动词：（1）表示感觉的感官动词，如：see, hear, notice等。如：Do you hear the noise of the plane? 你听见飞机的声音了吗？（2）表示态度、感情、心理状态等的词，如：like, love, want, hope, hate, know, think, agree, believe等。如：I love my mother. 我爱我的妈妈。（3）have/has作“拥有”讲时。如：Do you have a book? 你有一本书吗？用法1. 表示现在（说话瞬间）正在进行或发生的动作。如：He is watching TV now. 现在他正在看电视。Look!They are playing basketball on the playground. 看！他们正在操场上打篮球。2. 表示当前一段时间内的活动或现阶段正在进行的动作（说话时不一定正在进行）。如：We are working on a farm these days. 这些天我们一直在农场干活。3. 表示位置转移的词，如go, come, leave, arrive等常用进行时表将来，一般同表示将来的时间状语连用。如：He is leaving for Shanghai tomorrow. 他明天要去上海。四、过去进行时概念过去进行时表示过去某一时刻或某段时间正在进行的动作。构成主语+was/were+动词的现在分词+其他。如：She was writing a story at that time. 那时她正在写一个故事。时间状语常用的时间状语有at that moment, at that time, at this time yesterday, at 8:00 last night, when, while, just as等。用法1. 表示过去某一时刻或某一段时间正在进行的动作。如：What were you doing at nine oclock yesterday evening? 昨天晚上9点钟你正在做什么？2. 表示从过去某一时间的角度看将要发生的动作，常用于瞬间动词，如：go, come, leave等。如：They were leaving a few days later. 几天以后他们要离开。3. 用在含有时间状语从句的复合句中，延续性动词用过去进行时，非延续性动词用一般过去时。如：While we were talking, the boy came in. 当我们正在交谈的时候，这个男孩进来了。They were watching TV when I entered the room. 当我进入房间的时候，他们正在看电视。过去进行时与一般过去时的区别过去进行时表示过去某一时刻正在进行的动作；一般过去时表示过去发生的一个单纯事实，动作往往已经结束。如：Mary wrote a letter to her friend last night. （信已经写完）Mary was writing a letter to her friend last night. （信不一定写完）【活学活用】 用所给动词的适当形式填空。1. Look!The Greens_（play） games togetherin the park. What a happy family!2. I_ （read） a book when my parents came back home last night.3.

She_ （take） a walk every morning unless the weather is terrible. 2. I didnt know if Amy_ （come）.3. It is said that the pop singer_ （appear） in our city next week.4. Why are you in such a hurry, John?There_ （be） an NBA basketball game in ten minutes.七、现在完成时概念现在完成时表示过去已经发生的动作对现在造成的影响和结果。构成助动词（have, has）+过去分词。过去分词有规则变形和不规则变形两种，规则动词的过去分词的变形与该动词过去式的变形相同。时间状语常与already, just, yet, lately, recently, never, ever, once, twice, three times, before等连用。用法1. 表示结束、结果。动作发生在过去，而且终止于过去，但其结果对现在仍有影响。如：Ive written down some ideas. 我已经写下了一些想法。Ive just finished my homework. 我刚刚完成了我的作业。2. 表示继续。动作或状态从过去某一时刻开始，一直持续到现在，并有可能延续下去，要用持续性动词（否定句除外）。常与for和since引导的表示一段时间的状语连用（for+一段时间, since+时间开始的起点）。常用的时间状语还有in the last（past）.， for a long time, so far, ever since等。如：I have studied at this school for two years. 我在这所学校上了两年学了。Uncle Wang has worked in the factory since it opened. 自从这家工厂开办以来，王叔叔就在这儿工作。3. 表示经验，即从过去到现在之间曾经经历过的事情。如：I have never been to Mount Emei before. 我以前从未去过峨眉山。注意事项1. 现在完成时不能与表示过去的时间状语连用，如yesterday, last night, just now, last Sunday, in 1999, two weeks ago, when I arrived等；但可以和包括现在在内的一些时间状语连用，如today, this week, this month, this term, this year等。如：We have learned 500 English words this term. 我们这学期学了500个英语单词。2. 现在完成时的谓语动词如果是短暂性动词，通常不能与表示一段时间的for短语及since短语（或从句）等连用。应将短暂性动词改为相应的延续性动词。转换情况如下：borrowkeep, buyhave, diebe dead, come （to）be （in）, go/leavebe away, becomebe, fall asleepbe asleep, beginbe on, go outbe out, joinbe a member of, marrybe married。如：He has been away since last week. 自从上周他就离开了。How long have you kept the books? 你借这些书多长时间了？注：在否定句中，短暂性动词可以和表示一段时间的状语连用。如：I havent borrowed a book for a long time. 我好长时间没有借过一本书了。3. have/has been to与have/has gone to的区别：have/has been to表示“去过某地”，已经回来了或有去过某地的经历；have/has gone to表示“去某地了”，还没有回来。如：Mary has been to Shanghai twice. 玛丽去过上海两次。（玛丽已不在上海了）Mary has gone to Shanghai. 玛丽到上海去了。（玛丽已不在出发地了）现在完成时与一般过去时的区别侧重点不同。现在完成时是与现在有关的状态，属现在时态范畴，它侧重于过去的动作对现在造成的影响；而一般过去时是一种过去时态，侧重于表示过去的动作，与现在无关。如：I closed the door five minutes ago. 我五分钟前关上了门。（强调动作发生在过去，现在门是否关上无从知晓）I have closed the door. 我已经关上了门。（强调门现在是关着的）八、过去完成时构成助动词had+动词的过去分词。用法1. 过去完成时表示在过去某一时间或动作之前已经发生或完成了的动作。它表示动作发生的时间是“过去的过去”。常与by, before, by the end of, by the time （that）等引导的时间状语从句连用。如：She had known my brother for three years before I met her. 在我见到她以前，她认识我哥哥已经3年了。By 10：30 she still hadnt arrived. 到10：30时她还没到。I found the letter after he had gone away. 他走了以后我找到了那封信。2. 过去完成时常用于宾语从句中。主句谓语为过去式（said, asked, told等），从句用过去完成时，此时从句中的动作发生在主句的动作之前。如：She said she had worked in a foreign company for five years before she became an English teacher. 她说在成为一名英语教师之前她已在一家外国公司工作了5年。【活学活用】 用所给动词的适当形式填空。1.
