中级美国英语Lesson27:现在完成进行时态

第二十七课　现在完成进行时态
一.本课要点及示例

在这一课里,我们学习现在完成进行时态, 比方 "一直在玩" have been playing.

"一直在学习" have been studying 等等.

现在我们先来听今天这一课的对话,内容是说彼得和玛丽谈起电脑的事情. 请 你注意听两位英文老师的发音和语调.

F: Peter, where have you been?

M: I've been playing Pac Man at the Arcade in the student union  .

F: Have you been wasting your time on those computer games again?

M: Not really, Mary. I've been studying a lot this week and I need a break.

F: Why don't you buy a computer and some of those games? Then you can play at home.

M: I have been looking at home computers.There are a lot of different kinds on market now.

F: I know, and they have been getting cheaper.

M: How do you know that?

F: I've been thinking of buying a home computer too.

现在英文老师再把对话用慢速度念一遍, 请你注意听.

F: Peter, where have you been?

M: I've been playing Pac Man at the Arcade in the student union  .

F: Have you been wasting your time on those computer games again?

M: Not really, Mary. I've been studying a lot this week and I need a break.

F: Why don't you buy a computer and some of those games? Then you can play at home.

M: I have been looking at home computers.There are a lot of different kinds on market now.

F: I know, and they have been getting cheaper.

M: How do you know that?

F: I've been thinking of buying a home computer too.

下面我请英文老师把对话里的现在完成进行时态句子再念一遍.

M: I've been playing Pac Man at the Arcade in the student union  .

F: Have you been wasting your time on those computer games again?

M: I've been studying a lot this week.

M: I have been looking at home computers.

F: They have been getting cheaper.

F: I've been thinking of buying a home computer too.

二.现在完成进行式

听了上面的句子, 我想你或许已经注意到现在完成进行时态是用 has been 或 是 have been 和加了 i-n-g 的动词构成的. 这种时态是用来表示一个动作从过 去一直持续到现在.

现在我请英文老师念一些跟刚才那段对话有关系的现在完成进行时态句子,每 个句子各念两遍, 请你听一遍, 跟着老师重复一遍.

M: Peter has been taking computer courses this semester.

F: Peter has been taking computer courses this semester.

M: Peter has been playing computer games this afternoon.

F: Peter has been playing computer games this afternoon.

M: Mary has been thinking of buying a home computer recently.

F: Mary has been thinking of buying a home computer recently.

M: Mary has been looking at home computers lately.

F: Mary has been looking at home computers lately.
