She must be out. 她不在家里，她必须外出了。留意：must表示推想，用于反意疑问句时，疑问局部不能用must, 应与其后面的动词保持相同。如：1She must be home, isnt she? 她必须在家里，是吗？2Tom must have a sister, hasnt he? / doesnt he? 汤姆确定有一个妹妹，是吗？5must与have to的区分。1表示主语主观的义务或必要时用must；表示主语客观因素的义务或必要时用have to。have to含有“不得不”的意思。如：I must be off. Thank you for your help. 我得走了。感谢你的协助。We have to be there early. 我得早点去那儿。2have to可以放在will后面构成将来时，而must那么不能。例如：他明天必需去那里。误：He will must go there tomorrow.正：He will have to go there tomorrow.正：He must go there tomorrow.辨析sound，noise和voicesound，noise和voice这三个名词都可表示“声音”，但是，它们表示的“声音”并不一样。1. sound作“声音”，“响声”讲时，可以指人或动物发出的声音，或物体碰撞的声言。这个词的运用范围很大。可以说，大自然的任何“声音”都可以用sound。例如：At midnight he heard a strange sound半夜里他听到一种惊奇的声音。Light travels much faster than sound光的传播速度比声音快得多。2. noise意为“噪音”、“热闹声”，常指不悦耳、不和谐的嘈杂声。例如：Dont make any noise! 别吵闹！The noise wakes me up噪音吵醒了我！The noise of traffic kept him awake车辆的热闹声使他睡不着。3. voice一般指人的声音，说话、唱歌。谈笑都可用voice。sound和noise不仅能指人的声音，还可以表示别的动物发出的声音；而voice除了有时可指鸟的声音外，很少表示其它动物的声音。例如：The girl has a beautiful voice那女孩嗓音很美。They are talking in low voices他们正小声交谈。When the teacher came into the classroom，our monitor spoke in a loud voice，“Stand up！”教师走进教室时，班长大声喊：“起立！”时间、条件状语从句的时态连词when，before，after，if引导的状语从句要特殊留意其时态。1当主句的谓语动词是一般将来时时，从句要用一般此时此刻时。如：The boy will be a writer when he grows up. 这个男孩长大后将成为一名作家。I wont go to school if it rains to- morrow. 假如明天下雨我就不去学校。2主句的谓语动词是情态动词+动词原形时从句的谓语动词也用一般此时此刻时。如：When the lights are red，the traffic must stop红灯亮时，车辆必需停下。3主句是祈使句时，从句也要用一般此时此刻时。如：Please dont go to bed before you finish your homework.在完成作业之前，请不要休息。4主句谓语用一般过去时时，从句也要用一般过去时。如：They talked about the party after people left. 人们离开后，他们谈论这次晚会状况。5.当主句的谓语是want, hope, wish等动词时，从句要用一般此时此刻时。例如：She wants to work in America when she finishes college.她大学毕业后想到美国工作。I hope to see him if I"m free.假如我有空，我盼望去看看他。must用法“六留意”must不完整。动词原形后面行；无改变是特征，主语可用各人称；表“必需”表示“推想”，“杜绝、制止”mustnt；否认答复neednt，牢牢记住这几点定能学好must。下面就这几点分述如下：1“must不完整，动词原形后面行”是说must有必须的词义，表达必须的语气和情感，但不能单独用作谓语，后面应加上动词原形。如：We must work hard at our lessons. 我必需努力学习功课。2“无改变是特征，主语可用各人称”是说must没有词形改变，任何人称代词都可作它的主语。如：IHe，She，You，Theymust do it well.我他，她你，你们必需做好这件事。3表“必需”是说must可以表示“必要、必需”之意，通常表示说话人的主观意志，或要求对方必需做某事。如：You must come earlier tomorrow. 你明天必项早点来。You must be more careful！你必须要多加当心！4表“推想”是说must可用来表示推想，有“必须、准是、必定”之意，表示说话人对所陈述的事情有一种可能性很大的推想。如：He must be our new English teacher.他准是我的新英语教师。Lucy must be at home now. 露西此时此刻必须在家里。5“杜绝、制止mustnt”是说表示“不应当、不许可、制止”做某事，语气比拟剧烈。mustnt是must的否认形式。如：Children mustnt play with fireIts dangerous！孩子们千万不能玩火，这很危急！6“否认答复neednt”是说，答复 must开头的问句，确定式用must，否认式用neednt，而不用mustnt。如：Must we do our homework every day? 每天我得做家庭作业吗？Yes，you must是的，你们必需做。疑难解析1. When many passengers are waiting for a bus, you must stand in line and wait for your turn当很多乘客在等车时，你必需排队等候。lwait for意思是“等待”。例如：Please wait for a minuteIll come back soon请等一下，我立刻回来。A boy is waiting for you at the gate for our school在校门口有一个男孩在等你。2in line意思是“成列，成行”。line多用来指竖行，row多用来指横行。例如：Please slim line请按列就坐。What row are you in？你在第几排？3turn名词，意思是“依次，次序”。例如：They came into the classroom in turn.他们依次走进了教室。Its your turn to speak.轮到你发言了。2. Everyone laughed at the womans mistake每个人都因为那妇女的错误而笑了起来。1laugh at意思是“讪笑，因而笑”。例如：Dont laugh at him. 别讪笑他。We all laughed at Li Lei when he was late for school again. 当李雷又一次迟到时，我都笑了。2) mistake是个可数名词。常见的词组有：make a mistake/ make mistakes, 例如：I made a few mistakes in my exercise-book. 我在练习本上出了几个错。Everyone may make a mistake. 人人都可能会犯错。3. Mr. Smile said he did not want to quarrel with the policeman. 斯迈尔先生说他不想与客家争吵。quarrel with意思是“与争吵”，后面接表示人的名词。quarrel about意思是“为而争吵”，后面接争吵的内容。“因某事与某人争吵”可写成quarrel about sth. with sb. 或者quarrel with sbabout sth.。例如：I dont want to quarrel with Jim.我不想和吉姆吵架。They are quarrelling about a maths problem. 他们在为一道数学题争吵。I quarreled about journey with Tom yesterday = I quarreled with Tom about journey yesterday昨天我与汤姆就旅游的事吵了一番。 教学建议教学内容分析本单元的主要交际功能工程是“制止和警告”，通过有关遵守交通规那么的话题表达出来。语法工程是l情态动词must和mustnt的用法。2由when，before，after引导的时间状语从句。3由if引导的条件状语从句。Lesson 65三局部的内容在训练如何遵守交通规那么的同时引出本单元重点语法工程：情态动词must及mustnt；when，before引导的时间状语从句及if引导的条件状语从句。这是本单元的主题，必需让学生反复练习。Lesson 66是阅读课文，表达一个外国妇女在候诊室等候就诊的故事，从而到达传播公共道德的目的。内容幽默，阅后可组织学生探讨文前的三个题目，让他们发表自己的看法。Lesson 67是有关生病的内容，对话有意识地重现了must, mustnt 和if从句，同时学习和复习了有关生病、看病的词语，从而为下一单元的教学作好了打算。其次、三局部着重练习when，before，if的用法。Lesson 68是一个有关家庭聚会的小故事。本课的教学目的与前面第66课一样，传播遵守公共道德。在表现手法上也与第66课一样，都是采纳最终点题的手法，从而使课文充溢幽默感。课文导读本单元的两篇课文是两个很好玩的故事，通过学习第一篇The queue Jumpers让我能够驾驭有关排队等候看病的一些学问，并养成排队等候的习惯，讲文明讲礼貌不做加塞者。学习其次篇You must stop making so much noise后我可以了解到西方人的一种社交场合party聚会，并从中学会讲究礼貌，在探望别人，或举办聚会时要把握好时间分寸，不能影响别人的生活。教学情态动词must的用法情态动词must表示“应当”，“必需”。否认式must notmustnt表不“不应当”，“不许可”，“不准”，“制止”等。本单元mustnt主要用法是表示“制止和警告”。在答复must的问句时，否认式常用need notneednt或dont have to，表示“不必，”而不用must not=mustnt。因为mustnt表示“不行以”。表示推想“必须”，“必定”只用在确定句中，教师在向学生简要讲明其主要用法以后，通过大量的操练让学生驾驭。例如：1.
