3、 3）把该句式译成汉语时，往往用“已经”、“刚刚”、“过”或“了”等。  接触二：否定句式：现在完成时的否定句式是“haven't（hasn't）过去分词”。如： We havent studied Unit 2 yet   The train hasn't stopped yet 接触三：疑问句式 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。 Have you read this story book yet？ 特殊疑问句及反意疑问句结构如下： What have you done with my bike?

4、 You have read this story book, haven't you? 注意：1）现在完成时的一般疑问句往往在句末加yet。 2）把现在完成时的一般疑问句译成汉语时，往往译成“过吗？”、“已经了吗？”等。 3）其肯定回答用“Yes，have（has）”，否定回答用“No，haven't（hasn't）”，有时用“No，not yet”或“No，never”。 2. 知识点过去分词（规则ed）1）Worked，visited，asked，played，stayed 2）liked lived moved3）stopped dropped robbed p

19、#160;    He _came_(come) to our school last year/in 2002.3.         They _have cooked_(cook) the supper already.4.         They _cooked_ (cook) the supper half an hour ago. 方法汇总1. 在做动词填空这类型的题时，首先应该先从上下文去判断

20、时态，然后再在句中找关键词，类似于“never”、“for+一段时间”、“since+固定一个时间点”这种显性的提示。2. 注意动词时瞬时动词还是延续动词，以及瞬时动词和延续动词间的转化。3. 一般过去时是指过去做了，而现在完成时是指过去到现在持续的一种状态或一直都在做。 课后练习现在完成时巩固练习Multiple choice1.  Youve never seen such a wonderful film before, _B_?A havent you B have you C do you D dont you2. -Ann has gone to Shanghai. -So _D_ her parents.
