allowed in the museum.
Sandy:That’s too bad! Do you think we may be allowed to take
photos if we don’t use a flash

if you don’t use a flash, then it may be OK.

被动语态
我们已经学习了一般现在时的被动语态和一般过去时的被动语态，它们的结构为：
时态 被动语态结构
一般现在时 am/is/are + 及物动词的过去分词
一般过去时 was/were + 及物动词的过去分词
What will we learn today？
I don’t think sixteen-year-olds should be allowed to drive. I agree. They aren’t serious enough.
Do you think teenagers should be encouraged to make their own decisions No, I don’t agree with this. Teenagers are too young to make their own decisions.
Teenagers should not be allowed to have part-time jobs. I disagree. They can learn a lot from working.
Do you think we may be allowed to take photos if we don’t use a flash If you don’t use a flash, then it may be OK.
Grammar Focus
Read the following sentences and find out the common features.
含有情态动词的被动语态的结构为：
情态动词+ be +及物动词的过去分词;
变为否定句时只需要在情态动词后加not
1.定义
含情态动词的被动语态用来说明某个被动性动作所反映出的感情和态度。常见情态动词有：can, may, need , must, should等。
含情态动词的被动语态
2.构成：情态动词+be+过去分词
eg:镇上需要种更多的树。
More trees should be planted in the town.
句式 结构 示例
肯定句 主语+情态动词+be+及物动词的过去分词(+by…) Teenagers should be allowed to go shopping.
否定句 主语+情态动词+not+be+及物动词的过去分词(+by…) The word can’t be used in this sentence.
一般疑问句 情态动词+主语+be+及物动词的过去分词(+by…) Must the work be finished today
特殊疑问句 特殊疑问词+情态动词+主语+be+及物动词的过去分词(+by…)？ Who should be asked for help
3.句式
e.g. Many trees should be planted in the mountains.
This book can be taken home.
This problem can’t be worked out very easily.
Must the work be finished at once
【拓展】
“动词+名词+介词”构成的短语动词(如take care of, pay attention to等)变为被动句时，通常把整个短语当作一个及物动词来处理。
e.g. You should pay attention to your health.
→Your health should be paid attention to.
含有情态动词的主动句变为被动句时，有如下步骤：
（1）把主动句的宾语变为被动句的主语；
（2）主动句中的谓语变为“情态动词 + be + 及物动词的过去分词”；
（3）主动句的主语在被动句中变为by的宾语；
（4）其他成分不变。
主动句：We should plant trees in spring.
被动句：Trees should be planted in spring.
4.含有情态动词的主动句与被动句之间的转换
将下面三个句子改写成被动语态。
1. He cleans his bedroom every day.
2. He cleaned his bedroom yesterday.
3. He should clean his bedroom in the morning.
______________________________________
His bedroom is cleaned by him every day.
His bedroom was cleaned by him yesterday.
______________________________________
______________________________________
His bedroom should be cleaned by him in the morning.
一般疑问句: 直接将被动语态的陈述句中的情态动词提前。
eg:Must this task be finished at once 这项任务必须立即完成吗？
注意: 含情态动词的被动语态的一般疑问句的回答，应保留原情态动词，但must表“必须”时，其否定回答应用needn’t；need表“必要”时，其肯定回答应用must。
如： 我的练习本必须现在上交吗？
— Must my exercise book be handed in now
是的，必须现在上交。/ 不，不必现在上交。
— Yes, it must. / No, it needn’t.
5.句式变换
5.句式变换
否定句：在情态动词后面加上not或never即可，但must表“必要”时
否定式为needn’t。
eg:这项任务没必要立即完成。
This task needn’t be finished at once.
特殊疑问句：由特殊疑问词加上被动语态的一般疑问句构成。
eg: 这项任务必须在什么时候完成？
When must this task be finished
反意疑问句：借助情态动词构成附加疑问部分。如：
eg:这座桥明年能建成，是吗？
This bridge can be built next year, can’t it
