1、-现在完成时复习教案-第 7 页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 app
2、le yet？他吃那个苹果了吗？ 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
3、的影响是：是否知道故事的内容） 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 、bef

12、. 非延续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
13、间段since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：
