Unit 4 Dont eat in class.一、知识概述 1学习和掌握情态动词can和have to的用法。2学习和掌握祈使句的含义和用法。 3学会谈论规则。二、语音知识 三、单元重难点解析 1Dont run in the hallways. 别在走廊里跑。 这是一个祈使句。祈使句是用来表示请求、命令、劝告等的句子，通常省略主语you。它的谓语动词用祈使语气（即动词原形）。句尾一般用降调。祈使句有肯定和否定两种。e.g.Come in, please! 请进！ Sit down, please. 请坐。 Lets go home. 我们回家吧。 否定的祈使句是在动词前（即句首）加 Dont。 e.g.Dont talk in class! 不要在课常上讲话！ Dont open the window! 别开窗！ Dont be late for school. 上学别迟到。 Dont listen to music in class.课堂上不要听音乐。2Dont arrive late for class. You must be on time.译文上学不要迟到。你必须准时到校。（1）arrive是不及物动词，不能直接跟表示地点的名词。如果要跟名词，就必须加介词in或at。at后接小地点，in后接大地点。e.g.We will arrive at the village at 5 tomorrow afternoon.我们将明天下午5点到达这个村子。How will you arrive in Shanghai？你们将如何到达上海？注意：如果 arrive后不接名词，就不用介词： e.g.After you arrive (here/there), please call me. 你到了（这里/那儿）后给我打个电话。（2）late adj. & adv. 迟，晚 e.g.Why are you late？ 你为什么迟到？ Sorry, I come late. 对不起，我来晚了。 be late for n. （对）迟到 e.g.Dont be late for work/class/meeting. 上班/上课/开会别迟到。 （3）must作为情态动词，表示“必须”、“务必”，有时还表示“一定”，起到加强语气的作用。e.g.You must come tomorrow.你明天必须要来。She must have this book.她一定有这本书。（4）on time是一个固定介词短语，表示“按时；准时”。e.g.We must get to school on time.我们必须按时到校。Planes and trains dont always arrive on time.火车、飞机并不总是准点到达。注意：与on time类似的另外一个短语in time表示“及时”的意思。（5）系动词be与形容词或介词短语联用，是英语一种常见的语句结构，表示某种状态。e.g.be quiet 保持安静 be strict 要求严格 be on time 守时；按时到 be at work 在上班在这种用法中，动词be主要承担着连系句子的语法功能，其后的形容词或介词短语则起这表意的作用。e.g.You mustnt be noisy, children.孩子们，你们一定不可喧闹。At this time of the day, children are at school.一天中的这个时候，孩子们在学校上课呢。3Dont listen to music in class.译文课堂上不要听音乐。listen是一个不及物动词，表示听什么，要用listen to的搭配。e.g.I often listen to music after school. 放学后我经常听音乐。辨析：hear与listenhear vt. 听见强调听的结果，不一定是有意识地听。 listen vi. 听 强调听的动作，但不一定听得到；如果后跟宾语，必须与介词to连用，即：listen to意为“听”。e.g.I cant hear you. 我听不见你说话。Listen! The bird is singing. 听！那个小鸟在唱歌。He listens carefully, but he cant hear anything.他仔细地听，但是什么也没听到。4What are some of the rules？译文其中的一些规则是什么？rule表示“规则”，为可数名词，构成的短语有： obey the rules 遵守规章school rules 校纪 = the rules of the school class rules 班规 = the rules of the class rule还可以用作动词，意为“统治，支配”。 e.g.The king ruled the country 500 years ago. 500年前，国王统治着这个国家。 5Can we bring music players to school？译文我们可以带音乐播放器来学校吗？（1）can为情态动词，情态动词不表示动作或状态，不能单独作谓语，没有人称和数的变化。疑问句直接把can提前到句首，否定句在can后加not，省略形式为cant，其后接动词原形。can 的用法和意义有许多种，在本单元内我们学习它表示“许可”的用法。 e.g.Can I sit here？ No, you cant. 我可以坐在这里吗？不能。 Can I go home now, Mr. Li？ 李老师，我现在可以回家了吗？ You can go now. 你现在可以走了。 注意：can还有一种最常见的意义“能，会”，表示具有某种能力。 e.g.Can you play basketball？你会打篮球吗？ Yes, I can. 会。 Can she speak English？ 她会讲英语吗？ No, but she can speak French. 不会。但她会讲法语。 （2）bring表示“带来，拿来”的意思，注意take和bring都可表示“带、拿”的意思。它们后面都可接名词、代词作宾语，也可接双宾语。其区别在于：bring指从别处把某人或某物带来、拿来。take则指从这里把某人或某物带走、拿走。e.g.Please bring me some apples.请给我拿些苹果。Why not take some apples there？为什么不带些苹果去那呢？6And we always have to wear the school uniform.译文并且我们总是必须穿校服。have to 不得不，必须 （1）have to连起来用作情态动词，第一、二人称和第三人称复数用have to，主语是第三人称单数时用has to。我们/我/你/你们/他们明天不得不去那儿。 She/He/Jim has to stay there. 她/他/吉姆不得不呆在那儿。 （2）与其它情态动词不同，含有情态动词have/has to的句子在变成疑问句或否定句时要借助于助动词do或does，回答时也一样。 e.g.Do you have to leave now？ Yes, I do. 你不得不现在离开吗？是的。 Does Tom have to go with his parents？ Yes, he does./No, he doesnt. Tom不得不和父母一起去吗？是的。/不，不必。 注意：当前面用了助动词时，后面的 has也应用have。（见上例句） 7practice v. 练习，实践 （1）practicen. You must practice your spoken English every day. 你必须每天练习你的英语口语。 （2）practicev-ing 如果 practice后接动词，应该把这个动词变成-ing形式： e.g.Jim practices playing the piano every day. 吉姆每天练习弹钢琴。 8After dinner, I cant relax either.译文晚饭后我也不能放松。副词either表示“也”，用于否定句句末，用法与表示肯定或陈述的副词too相似，可用逗号与语句的猪蹄隔开。e.g.You like English. I like it, too.你喜欢英语，我也喜欢。My father cant speak English. My mother cant (speak it), either.我爸爸不会讲英语，我妈妈也不会。9There are a lot of things you can do.译文有许多你可以做的事情。此句中a lot of things you can do是一个名词短语，句子you can do起着修饰、限定名词things的作用。英语中当句子限定修饰名词时要放在该名词之后。e.g.There are a lot of songs you can sing.有许多歌曲你可以唱。There are a lot of books you can read.有许多书你可以看。10Parents and schools are sometimes strict, but remember, they make rules to help us.译文父母和学校有时候是很严格，但是记住，他们制定规则是为了帮助我们。（1）strict adj. 严格的 be strict with sb. 对某人严格 be strict in sth. 对某事严格 e.g.Father is strict with us.父亲对我们很严格。 He is strict in his work.他对工作很严格。 （2）remember为动词，意为“记住；想起”。 e.g.It is important to remember the words. 记住这些单词很重要。拓展： remember to do sth. 意为“记得/记住去做某事”，表示这件事还没有做。e.g.Remember to eat healthy food. 记住吃健康的食物。Remember to close the window. 记得关窗。 remember doing sth. 意为“记得做过某事”，表示这件事已经做了。e.g.I remember having lunch. 我记得吃过午饭了。单项1Can your mother _ a car?
