1、6现在完成时态（秘笈）1. 用法：到现在为止已经完成的动作或事情。例：Yesterday I finished my homework, thats to say, I have finished my homework now.某种情况从过去某一时刻开始一直持续到现在，并且有可能继续下去。例：I have lived here since 1990.2. 现在完成时的构成： havehas+过去分词3. 现在完成时的四个基本句型肯定句 He has already finished the work. 一般疑问句 Has he finished the work yet?否定句 He has

2、 not finished the work. 两回答 Yes ,he has. No, he hasnt.特殊疑问句 What has he done? 4. 在下列情形下用现在完成时1九词语already 已经 肯定句中或句尾 例: I have already found my pen. = I have found my pen already.yet已经 否定句和疑问句句尾 例：I have not finished the work yet.Have you bought a computer yet?ever曾经 句中 例：Have you ever seen pandas?ne

5、e he came here.4如果句子里面没有时间状语，汉语意思能够加“已经”，往往用现在完成时态。例：Have you lost your library book? 你已经弄丢了从图书馆借的那本书吗？5现在完成时态还常常用于下列句型They have planted many trees in the last few years. 在过去的几年，他们已经种了很多树。This is the best book I have ever read. 这是我曾经读过的最好的一本书。It is the first time I have played the computer games. 这是

6、我第一次玩电脑游戏。5. 在现在完成时中，短暂动词不能和一段时间状语连用例：He has bought the book for 3 years.（错）因buy这个一次性动词不能和一段时间for 3 years连用, 改正的办法有五种： He has bought the book. (去掉一段时间for 3 years) He bought the book 3 years ago (改为一般过去时，使句子的意思不变) Its 3 years since he bought the book. = 3 years has passed since he bought the book.（改为

7、固定句型 It is -since-） He has not bought the book for 3 years. （改为否定句） He has had the book for 3 years. （用延续性动词have代替buy）6. 还有其他短暂动词也是这种情况，可参照前面的五种办法改正，前四种改法都一样，第五种改法各不相同，举例如下：come/arrive/get to/reach be here例：I have come here for 3 years.（错） 改为：I have been here for 3 years.leave/go be away例：He has lef

11、续性动词：表示的动作是能延续的动作，这种动作可以延续下去或产生持久的影响。如：learn work stand lie know walk keep have wait watch sing read sleep live终止性动词：也叫非延续性动词，瞬间动词，一次性动词。表示的动作不能延续，即动作发生后立即结束，产生某种结果。在有了某种结果后，动作就不能再继续下去。如：leave start set out arrive reach get to begin stop shut turn off marry put put on get up wake fall join meet rece
