小学五年级英语语法:现在完成时

构成:主语+助动词have, has+过去分词

用法:

2) 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) 3) 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?

4) 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.

5) 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) 6) 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.

摘要: 小学五年级英语语法:过去式 表示过去发生的动作或事件, 常和表示过去的时间状语连用,如yesterday, last night, the day before yesterday, 3 days ago, 含有be动词的句子, 将动词变为过去式,am, is的过去式
