主动语态
被动语态
在英语中，动词有两种语态，即主动语态和被动语态。被动语态的基本结构是“助动词 be + 及物动词的过去分词”，其中助动词be有人称、数和时态的变化,其变化规则与be作为连系动词完全一样。
1.主动语态变为被动语态的方法
第一步:将主动语态的宾语改为被动语态的主语；
第二步:将主动语态的谓语改为“be+及物动词的过去 分词”结构；
第三步:将主动语态的主语改为介词by的宾语，放在谓语之后(有时可省略)。如图示：
主动语态:
被动语态:
They (主语）grow (谓语）tea (宾语）in the south-east of China.
Tea (主语）is grown (谓语）by them in the south-east of China.

③

定义概念
语态是动词的一种形式，表示主语和谓语动词之间的具体关系，分为主动语态和被动语态两种。主动语态表示主语是谓语动词所表示的动作的执行者。被动语态表示主语是谓语动词所表示的动作的承受者。被动语态是动词的一种特殊形式，一般来说，只有需要动作对象的及物动词才有被动语态。汉语往往用“被、受、给”等被动词来表示被动意义 。被动语态结构是由“助动词be + 及物动词的过去分词done”构成的。注意：be本身无词义，但有时态、人称和数的变化，其变化与时态中的变化一致。
二、各种时态的被动语态结构如下(以动词do为例)：
一般现在时：am/is/are+ done
The classroom is cleaned by us.教室被我们打扫。
一般过去时：was/were+ done
The kite was made by him yesterday.昨天，风筝被他制作。
现在进行时：am/is/are+ being+ done
Flowers are being watered by her.花儿现在正在被她浇。
现在完成时：have/has +been+ done
The work has been finished by Jim.工作已经被Jim做完。
一般将来时：will/shall/be going to + be done
Trees will be planted by them tomorrow.明天，树将被他们种。
过去进行时：was/were + being+ done
A letter was being written by her at this time yesterday.昨天的这个时候一封信正在被写。
过去完成时：had+ been +done
The work had been finished by Jim.工作早已经被他完成了。
含有情态动词：can/may/must +be +done
He can be found by me.他能被我找到。
【重点句型】
Do you think we must keep teenagers away from the Internet 你认为我们必须使青少年远离网络吗？

五、阅读理解
With more and more cars on the road, the traffic jam will happen. How do we see it and how can we solve the problem
We know that the traffic jam happens in many places, especially in big cities. What are reasons for the problem On one hand, some people think that they should have a car when they have enough money, and then it's easy to go out and they can feel comfortable. On the other hand, a growing number of people hope to use their cars to show off (炫耀). What's more, years of research has shown that one of other reasons for the traffic jam is the driving habit. For example, many young people enjoy driving very fast, so they can feel excited. At last, most of them hardly care about the speed (速度) rules.
Many governments are working at how to make the traffic better. In my opinion, firstly, the governments should educate those people who have cars or plan to buy cars. The governments must make them know that the traffic jam is very serious, and set up a much more perfect traffic system (体系) to solve the traffic pressure.
( )26. What does the underlined word “jam” mean in Chinese
A. 事故 B. 堵塞 C. 规则 D. 房间
( )27. Why is the traffic jam getting more and more serious
A. Because there are not enough ways of transportation (交通方式).
B. Because there are fewer speed rules.
C. Because there are more and more cars on the roads.
D. Because many governments are working at how to make the traffic better.
( )28. Which of the following is NOT true
A. The reason for the traffic jam is that people have too much work.
B. The reason for the traffic jam is the driving habit.
C. The reason for the traffic jam is that some people want to show off.
D. Some people think that they should have a car when they have enough money, and then it's easy to go out and they can feel comfortable
( )29. What should the governments do to make the traffic better
A. They should educate those people who are young.
B. They should set up a much more perfect traffic system.
C. They shouldn't allow people to buy so many cars.
D. They should hardly care about the speed rules.
( )30. What does the passage mainly talk about
A. Reasons why people want to buy cars.
B. How drivers should drive.
C. The traffic jam, reasons for it and solutions.
D. Many young people enjoy driving very fast, so they can feel excited.
