第二十七課　現(xiàn)在完成進(jìn)行時(shí)態(tài)
一.本課要點(diǎn)及示例

在這一課里,我們學(xué)習(xí)現(xiàn)在完成進(jìn)行時(shí)態(tài), 比方 "一直在玩" have been playing.

"一直在學(xué)習(xí)" have been studying 等等.

現(xiàn)在我們先來(lái)聽今天這一課的對(duì)話,內(nèi)容是說(shuō)彼得和瑪麗談起電腦的事情. 請(qǐng) 你注意聽兩位英文老師的發(fā)音和語(yǔ)調(diào).

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.

現(xiàn)在英文老師再把對(duì)話用慢速度念一遍, 請(qǐng)你注意聽.

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.

下面我請(qǐng)英文老師把對(duì)話里的現(xiàn)在完成進(jìn)行時(shí)態(tài)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.現(xiàn)在完成進(jìn)行式

聽了上面的句子, 我想你或許已經(jīng)注意到現(xiàn)在完成進(jìn)行時(shí)態(tài)是用 has been 或 是 have been 和加了 i-n-g 的動(dòng)詞構(gòu)成的. 這種時(shí)態(tài)是用來(lái)表示一個(gè)動(dòng)作從過(guò) 去一直持續(xù)到現(xiàn)在.

現(xiàn)在我請(qǐng)英文老師念一些跟剛才那段對(duì)話有關(guān)系的現(xiàn)在完成進(jìn)行時(shí)態(tài)句子,每 個(gè)句子各念兩遍, 請(qǐng)你聽一遍, 跟著老師重復(fù)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.
