三种时态的被动语态
一、教学设计
【教学目的】
1. Students will master the structures of the passive voice in three different tenses.
2. Students will master the use of the passive voice in three different tenses.
【教学流程】
Step 1 The Future Passive Voice
In this class, we are going to learn the passive voice in some different tenses. First let’s look at the future passive voice.
基本概念：一般将来时的被动语态表示主语为动作的承受者，且动作发生在将来某一时刻或阶段。
基本构成：will/shall be done（表示单纯的将来）
am/is/are going to be done（表打算、意图；也可表在最近的将来会发生的事）
be to be done（表按计划或安排会发生，也可表将来必定发生）
be about to be done（不与具体时间连用，常与when搭配）
e.g. The bridge will/is going to be rebuilt next year.
这座桥明年将被重建。
The medical team is about to start. .
医疗队就要出发了。
即学即练：完成句子
A new plan will be discussed at the meeting this afternoon.
①A new plan won’t be discussed at the meeting this afternoon. (改为否定句)
②Will a new plan be discussed at the meeting this afternoon (改为一般疑问句)
③What will be discussed at the meeting this afternoon (改为特殊疑问句，用what)
Step 2 The Present Perfect Passive Voice
Next，let’s look at The Present Perfect Passive Voice.
基本概念：现在完成时的被动语态强调一个发生在过去的被动性的动作，动作已完成并强调对现在造成的影响或结果。
2. 基本构成：have/has been done
e.g. Northern China has been swept through by a strong cold wind recently.
最近一股强冷空气横扫中国北方。
Those dirty clothes have been washed.
那些脏衣服已洗过了。
3. 注意事项：非延续性动词，如borrow，finish，begin，start，buy，open，join等构成的现在完成时的被动语态不能与表示一段时间的状语连用。
e.g. The project has been started for three months. (F)
The project has been on for three months. (T)
即学即练：完成句子
Professor Li will give us a lecture, but when and where has not been decided yet.
The plan has been studied by the experts three times.
Has the plan been studied by the experts three times. (改为一般疑问句)
How many times has the plan been studied by the experts (就three times 提问)
Step 3 The Present Progressive Passive Voice
Finally，let’s look at The Present Progressive Passive Voice.
基本概念：现在进行时被动语态表示说话时或现阶段某个被动的动作正在进行。
2. 基本构成：am/is/are being done
e.g. The question is being discussed at the meeting.
这个问题现在正在会上被讨论。
What is being done to the machine.
现在对这台机器要采取什么措施？
3. 注意事项：am/is/are + under/in + n. 有时可相当于现在进行时的被动语态。
e.g. The school is under construction now.
= The school is being built now.
学校现在正在建设中。
The new law is in use. = The new law is being used.
这项新法律正被使用。
即学即练：完成句子
① Another bridge is being built over the Changjiang River at present.
目前长江上正在建造另一座大桥。
② The baby isn’t being taken good care of.
这婴儿没得到很好的照顾。
How many houses are being built in the village
村里正在建造多少房屋？
Step 4 Practice
Now it’s time to put we have learned into practice. Please translate the following sentences.
一幢新的大楼将在明年建造起来。
A new building will be built next year.
最近一幢新的大楼建起来了。
A new building has been built recently.
一幢新的大楼现在正在建造中。
A new building is being built now.
under construction
Step 5 Summary
The structure of this micro lesson:
Okay, let’s go through the 3 passive voices of different tenses.
时态和语态 基本形式 时间状语
一般将来时的被动语态 will/shall be done am/is/are going to be done be to be done be about to be done next…, tomorrow, in+时间段, soon, etc
现在完成时的被动语态 have/has been done for+时间段, since, already, ever, never, just, yet, till/until, up to now, so far, in the past/last …years, recently/lately, etc
现在进行时的被动语态 am/is/are being done now, at present, at the moment, etc
I guess you have had a good idea of how to use the passive voice correctly.
