现在完成时复习教案

1、现在完成时复习教学设计 第一、现在完成时的构成。 1现在完成时的基本句式是“have（has）过去分词”。如： I have seen that film我已经看过那部影片了。 We have just finished our homework我们刚做完家庭作业。 注意：1）该句式中的have或has是助动词，has用于第三人称单数，其它人称一律用have。 2现在完成时的一般疑问句式是把助动词have或has提到主语之前。如： Have you read this story book yet？你读过这本故事书吗？ Has he eaten that apple yet？他吃那个苹果了吗？

2、 注意：肯定回答用：Yes，have（has）否定回答用：No，havent（hasnt）有时用：No，not yet或No，never 3现在完成时的否定句式是“have（has）+not过去分词”。如： We havent studied Unit 2 yet我们还没学习第二单元。 The train hasnt stopped yet火车还没有停下来。 第二、 现在完成时的用法。 1、现在完成时表示过去发生或完成的某一动作对现在造成的影响或结果。如： Have you read that story？你读过那个故事吗？（“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）

3、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） 2现在完成时态既涉及过去，又联系现在，它可表示动作或状态过去已经开始一直延续到现在，和由for或since引导的时间状语连用。例如： We have lived here for five years我们在这里住了五年了。 I have known him since he was a boy我从他还是个孩子的时候就认识他了。 第三、现在完成时常与一些词、词组连用 : 1、ever、never、already、yet、just 、before、recently、so

4、far 2、for +一段时间 : for two days 有两天了 3. in(during) the past/last一段时间 : in the past ten years 在刚过去的十年里 4. since + 过去某一个时间: since 1991 第四、have been to, have gone to have (has) been to表示曾经到过某地（通常现在已经回来了） My mother has been to London twice. 妈妈去过两次伦敦。（妈妈现在已经回来了，在家） have (has) gone to 表示已经去了某地（通常不在说话的地方） M

5、y mother has gone to London. 妈妈去了伦敦。（妈妈现在就在伦敦，不在家） 练习：用have been to, have gone to填空 1.Jenny is well-traveled. She has _ to Germany twice. 2.Jane isnt in now. She has _ to the office. Can I take a message? 3. My father is a successful businessman. Hes _ many countries. 4. Its a dangerous place. Nobod

6、y has ever _there. 5.The manager has _to Beijing. He will be back tomorrow. 6.The tiger of the zoo is missing. None of us knows where it has_. 第五、have been to,have been in have been to 去过某地，现在不在那里 I have been to Paris. Now I am staying in Zhuhai. have been in 一直呆在某地，后接地点 I came to Zhuhai in 2004. So

7、 I have been in Zhuhai for 2 years already. 练习：用have been to, have been in填空 1.The Greens _China for three years. We _the Great Wall twice. Its very beautiful. 2.Some of us _ Zhuhai for only a week. 3.My father _Guangdong several times. 4.Tony _ America before, so this time he will travel to France.

8、 5.The boss _ the office since early this morning. He works hard. 第六、瞬间动词和持续性动词用于完成时的区别 延续动词表示经验、经历； 瞬间动词表示行为的结果，不能与表示段的时间状语连用。 He has completed the work.他已完成了那项工作。 (表结果) Julia has borrowed the book. Julia已经借了那本书。 Ive known him since then. 我从那时起就认识他了。(表经历) Julia has kept the book for 3 days. Julia已借

9、了三天这本书了。 瞬间动词不能和表示一段时间的时间状语连用,但是他可以转换成相应的延续性动词. 1.直接用延续性动词 buy have catch(get) a cold have a cold borrow-keep come/go /becomebe put on- wear 2.转换成be+名词 join the army be a soldier join the Party be a Party member go to school be a student 3.转换成be+形容词或副词 diebe dead finish be over beginbe on leavebe aw

10、ay fall sleepbe asleep closebe closed 4.转换成 be+介词短语 go to school be in school join the army be in the army eg.我们买这本书三年了. We have had the book for three years. We bought the book three years ago eg.他感冒三天了. He has had a cold for three days. He caught a cold three days ago. 瞬间动词和持续动词的练习 判断正误，并改正： 1. An

11、n has become a teacher for 4 years. 2. Maria has borrowed the CD from me for a over a week. 3.Jeff has bought the bike since last Monday. 4.Norman has put the machine right for a few hours. 5.The students have finished the homework for a while. 6.The front door has been open for 8 hours already. 非延续

12、性动词表示状态有三种方法： （1）用相应的延续性动词来替换非延续性动词。句中的谓语动词一般用现在完成时，时间状语为“for 时间段”或“since 时间点（过去某一时刻或非延续性动词的一般过去时从句）”或用在how long的问句中。例如： They have been here for five years他们来这里已经五年了。 （这里come这一非延续性动词改成了be。） （2）用“非延续性动词的一般过去时一段时间ago”这一句型（即用一般过去时）。例如： They came here five years ago他们是五年前来这里的。 （3）用“It is（has been）时间段sin

13、ce从句（从句的谓语动词用非延续性动词的过去式）”这一句型。例如： It is five years since they came here自从他们来到这里已经有五年了。 第七、现在完成时和一般过去时的区别 现在完成时表示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，所以它不能和过去具体的时间连用,而一般过去时则可以。一般过去时常和过去时间短语连用。请看下面对话中一般过去时和现在完成时的不同。 A：Have you seen the film？ B：Yes，I have A：When did you see it？ B：I saw it a year ago 练习：用所给动词

14、的正确形式填空。 1.He _(work) in our school for one year. 2.He _(come) to our school last year/in 2002. 3.They _(cook) the supper already. 4.They _ (cook) the supper half an hour ago. 第八、现在完成时与中考题（选择填空）。 1I_ a letter from him since he left（天津市） Adidnt receive Bhavent got havent heard 2Where have you _ these days？ I have _to Dazhu with my friends（重庆市） Abeen；gone Bbeen；been Cgone；been 3.How long have you _ this book？（哈尔滨市） Abought Bborrowed Chad 4.Wheres Peter？ He _ to Nanjing（沈阳市） Ais going Bhas been Chas gone 5.Youve never seen such a wonderful film before，_ ？（河北省） Ahavent you Bhave you
