Grammar
编写人：徐恒侠 审核人：赵 军 班级___________ 姓名__________ 学习目标：学习现在完成时的被动语态 自主学习
I. 回扣课本
1. First as a PC and then as a laptop, I (use) in offices and homes since the 1970s.
2. Over time I (change) quite a lot. II. 现在完成时的被动语态的用法
1.表示一个被动的动作发生在说话之前,强调对现在造成的影响和结果. The door has been locked.
2.表示一个被动的动作或状态开始于过去,持续到现在,并可能持续下去,常与for 或since引导的时间状语连用,或用于How long...?句型中.
The important problem has been discussed for nearly two weeks. How long has the machine been used?
3．现在完成时的标志:recently /already/yet for+一段时间 /since+时间点 4. 现在完成时的被动语态：has/have been done He has been sent to study the new technology in the company.
否定句: He has not been sent to study the new technology in the company. 一般疑问句: Has he been sent to study the new technology in the company? 特殊疑问句: Where has he been sent to study the new technology?
How many shopping centers have been built in this city?

III. 边学边练：
Correct mistakes(改错):
1. The child has been taken good care by Grandma all these years.
2. A notice has been put on the wall.
但许多不及物动词加介词或副词构成的短语动词，相当于及物动词，也可以有被动语态。但短语动词是一个不可分割的整体，变为被动语态时，不可丢掉构成短语的介词或副词。
3. Great changes in the city, and a lot of factories . A. have been taken place; have been set up B. have taken place; have been set up
C. have taken place; have set up D. were taken place ,were set up
只有及物动词才有被动语态，不及物动词（词组）没有被动语态, 如:happen, take place, die, appear, disappear, fail, remain, lie, last, sit , stand, break out, come true, belong to等．
4. Which sentence is right?
(1) What has happened to your brother? (2) What was happened to your brother?
IV．现在完成时的被动语态应注意的几个问题
1.请注意现在完成时的被动语态的两个助动词,即have/has和been,两者缺一不可。 2. 请注意与一般过去时的被动语态的区别。一般过去时的被动语态所表示的动作或状态与现在的情况没有联系,而现在完成时的被动语态则强调与现在情况的联系. The bridge was built last year. 这桥是去年建成的。 The bridge has been built. 这桥已经建好了。
