语法回顾
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 完全一样。
1.一般现在时被动语态的各种句式结构
肯定式 主语+am/is/are+过去分词（ + by…)
否定式 主语+am/is/are + not +过去分词 (+by…)
疑问式 Am/Is/Are+主语+过去分词(+ by …)
特殊疑问词+ am/is/are+主语+过去分词（+ by ...)
被动不离“be” “p.p.”, “p.p.”前面助动be。
主谓一致莫忘记，am, is, are现在时。
2.一般现在时被动语态的基本用法
用法 示例
表示经常性或习惯性发生的被动动作 I am often asked the question by my pupils.
表示近期正在发生的被动动作 These days people are moved by a teacher named Zhang Lili.
描述某种常态化的被动的客观事实 The spaceship is mainly controlled by computer.
强调目前存在的针对行为主体人的被 限制性动作 You aren’t allowed to take photos.
3.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.
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.

What did you find out
探究二：含有宾语从句的主从复合句中的否定转移的用法。
当动词think, believe, suppose, imagine, expect, feel的主语是第一人称、谓语动词为没有任何副词修饰的一般现在时，它们的否定式实际上是对宾语从句的否定。表示说话者提出一种委婉的看法或主张。
I think that he will help us. —I don't think that he will help us.
我认为它不会帮助我们。
I believe that he is right. —I don't believe that he is right.
我认为他不对。
I suppose that he likes it. —I don't suppose that he likes it.
我想他不喜欢它。
I don’t think sixteen-year-olds should be allowed to drive.
动词前有其他副词修饰时，否定不转移。如：
I really don't think it's necessary for us to go there now. 我的确不认为我们有必要去那儿。
I feel strongly that he shouldn't do such a thing. 我强烈地认为他不应该做那样的事。
应该翻译为：我认为十六岁的孩子们不应该被允许开车。

What does it take to graduate from university Some papers or high scores in exams Well, these are not enough if you are a student at Tsinghua University.
According to a new rule of the university, students must prove (证明) themselves in the swim-ming pool. They need to pass a swimming test of at least 50 meters, and those who fail the test will be required to take a swimming course throughout their school years. By the time they graduate, they will have known how to swim; otherwise they can't graduate with their bachelor's degrees(学士学位).
The news made waves in Chinese social media (媒体). Some people praised the university for requiring a necessary skill that can save lives, and they also believed that the rule would help improve students' health. However, others questioned if it was fair to expect those who come from inland cities (内陆城市) to be able to swim.
In fact, this is not a new rule. Tsinghua University first made swimming a requirement in 1919 but later gave it up because the number of students became too large and there were not enough swimming pools in the school for them to learn swimming.
Anyway, it is still good news that Chinese students' health has become more and more valued. Why not just take this chance to learn one more life-saving ability
( )16.According to the passage, it takes for a student to graduate from Tsinghua University.
A. some papers
B. high scores in exams
C. passing a swimming test
D. all of the above
( )17.The underlined phrase “made waves” in Paragraph 3 most probably means “ ”.
A. caused a heated discussion B. spread widely
C. made a requirement D. proved the rule
( )18.The passage is mainly about .
A. different people hold different opinions on a new rule
B. Tsinghua University has made a new rule of graduation
C. Chinese students' health should be more and more valued
D. there is a new chance to learn another life-saving ability
V.阅读短文,根据其内容,从短文后选项中选出能填入空白处的最佳选项,选项中有两项为多余选项
When you are a teenager, it seems that every time you say, “I want to…”, your parents answer, “No, you can’t.” Teenagers often think they should be allowed to make their own decisions, 19.
Li Hai, a 15-year-old boy from Huarong, is a middle school student. He is often late for school because he stays up too late. 20. Unless he arrives at school on time, he will be punished by his teacher. Also, Li Hai thinks that he should be allowed to watch TV and play computer games as much as he wants. If his parents refuse his requirements(要求),21.____________.
“Maybe my son thinks the family rules are too strict or unfair,” says Mrs. Li. “But we think we’re doing the right thing. 22. We expect him to get into a good university.” Li Hai is always asking, “Could you make the bed for me ” or “Could you help me to sweep the floor ” 23.
His parents insist doing chores with him every weekend. Gradually he realizes the importance of doing housework. Sometimes he helps his mother with housework. These days, Li Hai knows his parents care about him and he must follow these strict family rules. Only then will he have a chance to become a better teenager.
A. Li Hai needs to spend more time on his study.
B. He likes doing housework.
C. His parents always ask him to go to bed early and have enough sleep.
D. He thinks doing housework is a waste of time.
