Unit 3 Teenagers should be allowed to choose their own clothes

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。

Unit 3 Teenagers should be allowed to choose their own clothes.1.被动语态：英语动词有两种语态：主动语态（the Active Voice）和被动语态（the PassiveVoice）。

主动语态表示主语是动作的执行者；被动语态表示主语是动作的承受者。

Ⅰ.被动语态由“助动词be +及物动词的过去分词”构成。

助动词be有人称、数和时态的变化，以下为几种常用时态的被动语态的构成：一般现在时：主语＋am / is / are （not）＋动词过去分词一般过去时：主语＋was / were ＋动词过去分词一般将来时：主语＋will ＋be ＋动词过去分词/ 主语+be动词+going to +be+动词过去分词含有情态动词的被动语态：情态动词＋be＋动词过去分词现在完成时：主语＋have / has ＋been ＋动词过去分词现在进行时：主语＋is / am / are + being ＋动词过去分词习题：（） wild animal zoo is going to__________in our city.built building（） lot of trees_________on the hill yesterday.planted be planted been planted planted( ) of the work________by now.finished been finished been finished( ) likes reading very much. Most of his money_______on books.spent spentⅡ.被动语态的用法：1.不知道谁是动作的执行者，或者没有必要指出谁是动作的执行者。

Eg: His new car was stolen. 他的新车被偷了。

（谁偷的，不知道）Letters are collected from his postbox at 7:30 every morning.每天早晨七点半有人来收他邮筒里的信。

［教材全析］友情提示SECTION ALanguage Goal:Talk about what you are allowed to do.Agree and disagree.语言目标：谈论你们被承诺做什么。

同意和不同意。

1a Read the statements below.Circle 〝A〞(for agree) or 〝D〞(for disagree).读下面的陈述。

圈出A(表示同意)或D(表示不同意)。

A D 1.I think teenagers①should be allowed to go out with their friends every night.我认为十几岁的青青年应当被承诺每晚同朋友们外出。

A D 2.Sixteen-year-olds should be allowed to drive.十六岁的青青年不应当被承诺驾车。

A D 3.Students should not be allowed to have part-time②job.学生们不可被承诺有兼职的工作。

A D 4.I don’t think twelve-year-olds should be allowed to get their ears pierced.我认为十二岁的青青年不应当被承诺打耳眼。

A D 5.I think twelve-year-olds③should be allowed to choose their own clothes.我认为十二岁的青青年应当被承诺选择自己的衣服。

含有助动词should的句子要变成被动语态，其方法是将主动语态中的宾语提到句首，然后在should后面跟被动语态的差不多结构be+v.过去分词。

将主语加上介词by放在句子末尾。

例题探究：Tom should be allowed to make friends with these teenagers by us.〔变成主动语态〕1b Listen and circle 〝T〞(for true) or 〝F〞(for false).听同时圈出T(对)或F(错)。

Unit 3 Teenagers should be allowed to choose their own clothes【单元话题分析】“没有规矩不成方圆”,每所学校、每个家庭都有自己的行为规范准则,该做什么,不该做什么。

本单元的核心话题就是谈论规则,发表自己的见解。

《英语课程标准》在情感态度和文化意识方面要求中学生在学习英语语言的同时,要学会遵守公共行为规范,并培养自身独立思考的能力。

通过对本单元话题的学习,大家一要学会谈论允许做的事和不允许做的事, 深刻了解中学生应该做什么,不应该做什么,建立自己正确的价值观念；二要针对现实生活中的各种行为规范和要求, 发表自己独立的见解。

本话题常见的命题形式主要有两种：一是根据自己的实际情况讲述身边的规则,有时要求谈论个人观点；二是根据内容提示写谈论规则的短文, 这种文体通常是夹叙夹议。

写作本话题常用的结构除了课本上的含有情态动词的被动语态结构should(not) be allowed to之外,have to，must，can’t，should，shouldn’t，you’d better等也很实用,大家应根据需要灵活应用。

【解题技巧】在很多情况下, 本话题的作文常带有议论文的色彩。

因此,在写作时要注意以下几个方面：1.主旨鲜明、论点明确,即要怎么做、做什么,这是谈论规则的基本要求。

因此,要做到具体、简练、开篇名义。

如果有个人见解,可在其后表达。

2．讲述个人观点时,要有论据支持,要讲原因。

说理要结合同学们的实际情况,尽量做到透彻明了。

3.恰当使用时态和语态。

议论文或夹叙夹议的作文会涉及到多种时态,要根据内容选择选择恰当的时态,时态也有一定的感情色彩。

为了使作文内容更加客观公正, 常常会用到被动语态；为了使作文给人以亲切的感觉, 常以第一人称的口吻写作,这时常用主动语态。

写作时应根据需要确定使用哪种语态。

4.结构清楚。

议论文常见的结构是,先摆论点,在进行论证,最后得出结论。
