学位英语语法考点归纳总结:现在完成时部分介绍如下,大家想要快速掌握英语语法知识点,最好的办法就是结合真题进行训练。


现在完成时构成:主语+助动词have, has+过去分词


用法:


1) 表示过去发生的和现在有某种联系的动作,常和just, usually, already, since等时间副词连用


I have just had lunch. (饱了,不用再吃了)


He has had a cup of tea.(不渴了,不用再喝)


They have already had their holiday. (不能再度假了)


The boy has already read the book. (已经知道书的内容了,不用再看了)


2) 询问别人是否做过某事一般用现在完成时:


Have you finished your homework?


Have you been to Beijing?


Have he seen the film?


3) 表示开始于过去并持续到现在的动作


I have lived in Beijing for twenty years.


I have worked for this school for 1 year.


4) 表示一种经历,经验:去过…地方,做过…事情,经历过…事情


I have never had a bath.


I have never seen a film.


I have never been to cinema.


I have ever been to Paris.


Have been to表示去过,have gone to 表示去了


I have been to London.(人已经回来)


He has gone to London.(人还在那里)


5) 表示一种结果, 一般不和时间副词联用


I have lost my pen.


I have hurt myself.


He has become a teacher.


She has broken my heart.


句型变化:


★变疑问句将助动词移到句首,变否定句在助动词后面加not.


e.g. Have you lost your pen? I have not lost my pen.


★肯定回答及否定回答


Yes, I have. No, I have not.


★特殊疑问句:


What have you done?


What has he done?


一般过去时与现在完成时的区别:


凡是有明确的表示过去的时间状语的句子为过去时


注意:有些动词表示的动作有一个终点,不能再延续,因此不能和表示一段时间状语连用


错:I’ve left Beijing for 3 days.


对:I left Beijing 3 days ago. I have been away from being for 3 days.
