3、Grammar：
被动语态（Be +done）
三、具体知识讲解：
语法：
被动语态：句子的主语是谓语动词的动作的承受者或者主语是动作的对象，因此只有及物动词才有被动语态。如：
Englishis spoken by many people in the world.
世界上的许多人讲英语（英语由世界上的许多人讲）。
句中的English就是动词speak的承受者。当要强调动作执行者的时候，用介词by加上这个动作的执行者来表示就可以了，如句中的bymany people结构。
被动语态的构成： be + done （动词过去分词），各种时态由be 表示，如：
Our classroom is cleaned everyday, but it wasn't cleaned yesterday. It will be cleaned byGroup1 tomorrow.
我们的教室每天都打扫，但昨天没扫，明天由第一组清扫。
1a中的被动语态是由情态动词should+ be +done 组成。
1. I think teenagers should beallowed to go out with their friends every night.
我认为应该允许青少年每天晚上和朋友们出去。
2. I don’t think fifteen-year-oldsshould be allowed to get their ear pierced.
我认为不应该允许十五岁的孩子扎耳眼儿。
get sb. / sth. + adj.（形容词）:意思为“遇到某种情况”或“使……处于某种状态中”，如：
How did the classroom get so dirty?
教室怎么搞得这么脏？
He often gets the answers wrong.
他经常把答案弄错。
3. He should stop wearing that silly earring.
他应该别戴着那个可笑的耳环了。
stop doing sth. 停止做某事
It’s time for class. Please stoptalking.
该上课了。请不要讲话了（请停止讲话）。
4. He doesn’t seem to have manyfriends.
他似乎没有太多的朋友。
似乎；好像；看来
They seemed to be tired. They workedall day.
他们看起来很疲劳，工作了一整天了。
5. He needs time to do homework.
他需要做作业的时间（他需要时间做作业）。
动词不定式to do homework修饰名词time作定语,如：
I have many questions to ask theteacher.
我有许多问题要问老师（我有许多要问老师的问题）。
6. For example, I have stay at home onschool nights.
譬如，我平时晚上得呆在家里。
on school nights 是指平时上学时间的夜晚（除周末外）。
另外，当明确说到哪一天晚上的时候用on , 而at night意为“在夜间；在晚上”。如：
He often goes out with his friends atnight.
他经常在晚上和朋友们出去。
7. I have to be home by 10:00 pm.
我得晚上十点以前回家。
by：介词，到……为止

我昨晚做作业一直做到11点为止。
8. That would be a good way to keepboth teachers and students happy.
