五、语法精讲

含情态动词的被动语态
1.含有情态动词的被动语态的结构
含有情态动词的被动语态由“情态动词 + be + 及物动词的过去分词 ( + by... )”构成。

Can tables be made of stone 桌子能用石头制造吗？（疑问句）
（2） 含有情态动词的被动语态变为否定句时，应在情态动词后面加not；变为一般疑问句时，应将情态动词移到句首。
例如：

（3） 含有情态动词的主动语态变为被动语态时，要把主动语态中的宾语变为被动语态中的主语；主动语态中的谓语动词变为“情态动词+助动词be+过去分词”；主动语态中的主语变为介词by 的宾语，放在句尾（如果不强调动作的执行者，by短语常可省略）。
例如：

→Fourteen-year-olds should be allowed to choose their own clothes（by parents）父母应该允许十四岁的少年选择他们自己的服装。
六、作文积累
1.本单元以“规则”为话题，结合此话题就学校和家里的规章制度进行了论述。写作中常涉及这一话题。写作时可以发表自己的观点，在表达观点时，要有理有据，观点不能偏激。
写作此类话题作文的常用表达有：
（1）I think teenagers should be allowed to …
（2）I agree that…
（3）I don’t agree with…
【典型例题】
（1）国有国法，校有校规。在你的学校中一定有很多的规章制度规范同学们的行为。请你写一篇短文，向大家介绍一两条校规或校纪，并谈一下自己的看法。
There are many rules in our school.
At our school we have to wear uniforms every day. The problem is that all my classmates think the uniforms are ugly. I think young people should look smart, so I’d like to wear my own clothes. If we have to wear uniforms, we should be allowed to design our own uniforms. That would be a good way to keep both teachers and students happy.
Although we have different views on the rules, I think everyone should obey the school rules.
（2）假设你是珍妮, 这周末, 你们学校组织同学们去动物园参观, 但是同学们对动物园的规则一无所知。请你根据表格提示写一篇关于动物园规则的作文, 让同学们了解动物园的规章制度。
With the development of science and technology, more and more students have a mobile phone of their own. Should students be allowed to use mobile phones at school Some people give a yes answer. They say with mobile phones, parents can get in touch with their children at any time. Students can also do fun things on their mobile phones, like listening to music and surfing the Internet. Others are against the idea. They say mobile phones can make students pay little attention to their study. Some even use mobile phones to cheat in exams. In my opinion, it's OK to have mobile phones at school, but schools must have rules about using mobile phones, for example, when and where to use them. Mobile phones can be a great help if they are used properly.
（3）假如你是张静，你的美国朋友Jenny发电子邮件向你询问你们学校的校规，请你根据以下提示给她回复一封邮件介绍你们学校的校规。
提示：
在校必须穿校服：衣服干净、整洁；
不许迟到早退；
不准从楼上往下扔杂物；
玩耍时不能使用刀等尖锐的器械；
在校不扎耳洞、不戴耳环、不抽烟、不喝酒。
Dear Jenny，
