人教版新目标英语9年级全册讲解-Unit 3Unit 3 Teenagers should be allowed to choose their own clothes.重点、难点、考点及疑点注释1. I don’t think twelve-year-olds should be allowed to get their earspierced. (P18)我认为不应该允许12岁的孩子穿耳孔。
(1)当主句的主语是第一人称I或we，谓语动词是think, believe, suppose,guess等词时，其后的从句不能是含有not的否定句；若要否定，须将not提到主句。
在翻译时，按汉语习惯译作否定从句。
例如：“我想他不会给你打电话的”应译为I don’t think he will give you a call而不是I think he won’t give you a call。
特别提示若把此类句式变成反意疑问句，其助动词及主语要根据从句确定，而肯定/否定则要根据主句来确定。
We think you can help him, can’t you? 我们认为你能帮助他，不是吗？I don’t think he is a good student, is he? 我认为他不是个好学生，对吗？(2)本句中的twelve-year-olds相当于twelve-year-old teenagers，意为“12岁的孩子/年轻人”。
知识拓展数词和一个相应的名词单数用“-”连接起来，可以构成一个合成形容词。
常见的还有：two-month holiday 两个月的假期a sixty-pound stone 一块60磅的石头(3)get their ears pierced属于“get+名词/代词+动词的过去分词”结构，表示“使……被做”，“请人做……”。
Go and get your hair cut! 你去理理发吧。

Although they’re young, they have to make many important choices by themselves. They need to think about questions like these.Should I go to college ? What kind of jobs do I want ? However, other people also influence their choices . Who influences Teenagers ? Teenagers were asked this question and here’s what they said.It depends on the kind of choice . When teenagers buy things , friends are the most important influence. This is especially true for clothes and music. TV shows, advertiserments(广告)and parents also influence teenagers. In more serious things, parents are probably the most important influence. Some teenagers say it’s best to regard both parents and friends as influences. James, a seventeen-year-old boy says he’s “Just a crazy man”. He also says , “Parents are really important because they can tell you what’s right and wrong.”But teenagers also feel they need to make choices to make their own mistakes.As one teenage girl said, “If our parents don’t let us make our own choices, maybe in the future we won’t know how to do it .” And they feel friends can often be a big help, especially because friends sometimes know more about their situation(处境)than their parents do.Do you depend parents or others when you decide what to do and how to do it ? whoever(无论谁)you depend on ,the correct choice is the most important. Your future is in your hand.根据短文内容，判断正（T）误（F）( )1.When teenagers buy clothes and music, friends are the most important influence.( )2.People from 13 to 19 can be called “teenagers”.( ) shows and advertisements can’t influence teenagers.( )4.Sometimes friends know more about teenagers’situation than their parents.( )5.In more serious things , friends are probably the most important influence.

He or she teachers something behind the culture(文化)of the country. In a country such as the United States, people with different histories, cultures and languages join together and they pay much attention to personal ideas. Teachers try to make each student special. Students do not have to remember a lot of information, instead, they work and find answers by themselves. There is often discussion in the classroom.At an early age students learn to have their own ideas. Their education encourages personal thought(思想).The important is placed on how to arrive at an answer and not only to get the correct answer.In most Asian countries, people have the same language, history and culture. Perhaps for this reason, the education there pays more attention to group goals than personal ideas. Children in China and Japan often work together and help each otheron homework. In the classroom, the ways of teaching are often very traditional. The teacher says , and the students listen. There is not much discussion. Instead, the students repeat(重复)rules or information that they have been taught in order to keep than in mind.In many ways there differences e from different educational ideas. In Western countries teachers are taught students to learn by themselves. In some Asian countries, however, teachers often feel that their job is to pass knowledge to students.回答问题1.Do students in the United States have to remember a lot of information ?2.There is often discussion in the classroom in America , isn’t there ?3.What does the education in the United States encourage ?4.Which does the education is some Asian countries pay more attention to , group goals or personal ideas ?5.Put the sentence “In some Asian countries, however, teachers often feel that their job is to pass knowledge to students.”into Chinese.四．词语运用。
