Unit 4 Dont eat in class一、知识点解析 1.Dont fight.不要打架。fight作动词，意为“打架、打仗”。fight with sb“和打架”，“同（并肩）战斗”，后只接表示人或国家的名词。Eg:Dont fight with him.不要和他打架。2. 辨析： get to/ arrive 相同点：都是“到达“的意思不同点：get to+地点；arrive at+小地点（车站等）；arrive in+大地点（国家等）注意：get to与地点副词（here/there/home）不用介词toEg:I want to go to Beijing.I got home at 15:00.我下午三点到的家。arrive是不及物动词，后面若接地点名词则要和in/at连用，接地点副词时则不用介词。Eg: I arrived home at 15:00. =I got home at 15:00.He arrived in Shanghai yesterday.他昨天到的上海。He arrived yesterday.他昨天到的。【典型例题】-What time do they_shcool?-At about 4:30 p.m.A.come B.go C.arrive D.arrive at3. on time“准时，按时”，指按规定的时刻不早不晚。Eg:He always go to school on time.他总是按时上学。in time“及时”，指没有迟到，时间还充裕。Eg:Fireman reached the house on fire in time.消防员及时赶到那幢失火的房子。4.辨析take,bringtake“带走，拿走”指把东西从说话地带到别的地方，和there连用Can you help me take the books to the classroom?你能帮我把这些书带到教室吗？bring“带来”指把东西从别处带到说话地，和here连用。Bring your homework here tomorrow , please.请你明天把作业带到这儿来。【典型例题】_away this dirty shirt and _ me a clean one.A.Take;bring B.Take;take C.Bring;take D.Bring;bring4. strict是形容词，意为 “严格的”； “严厉的”，通常与be动词连用。be strict with sb “对某人严厉”Eg:Mr. White is very strict with us. 怀特先生对我们要求很严格。 Teaches should be strict with students. 我们应该对自己要求严格。be strict in (doing) sth “对某事要求严格”Eg:Our boss is strict in our work. 我们的老板对我们的工作要求严格。 5.remember“记得，记住”，是及物动词，可以直接加名词。remember doing sth记得做过某事（已做）Eg:I remember seeing him once.我记得见过他一次。remember to do sth 记得要做某事（没做）Eg:Remember to post the letter for me.记得给我寄这封信。forget“忘记，忘了”，作remember反义词时，用法和remember相同。6.help作动词意为“帮助”，常用的结构有：help sb (to) do sth帮助某人做某事help sb with sth(n.)帮助某人做某事Eg:I often help him with his lessons.我常帮他学功课。help还可作名词，表示“帮助”，是不可数。 7.too many, too much与much too易混词组意义及用法例句too many形容词，“太，太多”，接可数名词There are too many people in the park.too much形容词，“太多”，接不可数名词I have too much homework today.much too副词，“太，非常”，接形容词或副词My mother is much too busy.【典型例题】I have _skirts and this one is _small for me, so you can take it if you like.A. too many; too much B. too much; much too C. too many; much too 8.either,too与also易混词意义及用法例句either“也”，用于否定句中，置于句末时用“，”隔开I wont go there, either.too“也”，用于肯定句句末，用“，”隔开I like dancing ,too.also“也”，用于肯定句句中,放在实意动词之前，be动词、助动词、情态动词之后。I also like English.【典型例题】I dont like her, _.A.also B.too C.either D.to10.have fun=have a good time 玩得开心，玩得愉快. 9.No talking ! 禁止交谈。no后面加上名词或动名词doing也表示不要做某事。与dont +do的用法相似。Eg:No wet umbrellas! / Dont put wet umbrellas here! 禁止放湿雨伞No food! Dont eat food here! 禁止吃食物 No smoking! Dont smoke here! 禁止吸烟 三、重点语法1. 情态动词have to 的用法：意思是必须、不得不它侧重于客观上的必要和外界的权威。 结构：have/has to do sth.不得不做某事 一般现在时：主语是第三人称单数时用has to，其它时候用have toEg:We have to wear sneakers for gym class. 在体育课上我们必须穿运动鞋。 Tom has to practice the guitar every day. 汤姆每天必须练习弹吉它。 （I had to get up at 5:00 am last Monday. 上周一我不得不早上5点起床。） 否定形式:主语+dont have to+动词原形+其他一般现在时:主语是第三人称单数时用doesnt have to,其它时候用dont have to. Eg:Nick doesnt have to wear a uniform. 尼克不必穿制服。 We didnt have to do our homework at once. 我们不必马上完成作业。 疑问句：Do 、Does或Did+主语+have to +动词原形+其他 Eg:-Do you have to stay at home on weekends? 周末你必须呆在家里吗 -Yes, I do. / No, I dont. 是的我必须。不我不必。 Did he have to go to bed by 11:00 last night? 昨晚他不得不11点前上床睡觉吗？【典型例题】Lucy has to wear sports shoes for gym class.(该为否定句)Lucy _ _ to wear sports shoes for gym class. 2.情态动词must的用法：must表示说话人的主观看法，及主观上的必要性，还用于命令或愿望。只用于现在时，无人称和单数的变化。在表示有做某一个动作的必要和义务，它的意思是“必须，应该”。Eg:You must finish your homework fist.你必须先完成作业。以must开头的一般疑问句，它的否定回答用neednt（不必要），不用mustnt（不允许），mustnt常用于否定句中表示“不允许，禁止”。Eg:-Must I go there on foot?我必须得走过去吗？ -No,you neednt.不，你不需要。 You mustnt park your car here.你的车不允许停在这儿。【典型例题】Its very warm outside.You _wear the coat.A.have to B.hadnt C.dont have to D.mustnt3.情态动词can的用法： 表示能力：会能，在第上册中已经学习这种用法 Eg:Can you play the guitar? 你会弹吉它吗Judy can speak a little Chinese. 朱蒂会说一点中文。 I can dance and sing. 我能唱歌又能跳舞。 表示允许、许可：可以、能即在这一课中新学的词义 Eg:Can the students run in the hallways? 学生们可以在走廊上跑吗We can eat outside. 我们可以在外面吃东西。Can I come in? 我能进来吗 注意：同样是情态动词can 和have to 的用法是有区别的，和大部分情态动词一样，can在否定句中直接在can后加上not；在疑问句中把can放到主语前面，并且没有人称和数的变化，而 have to 是有相应变化的，详情请参照上一条。 【典型例题】The children _play football on the road.A.can B.must C.mustnt D.may-Must I clean the blackboard?-No,you _.A.neednt B.mustnt C.cant D.may notYour mother _there,she has gone to America.A.must be B.could be C.may be D.cant be4. 祈使句（Imperative Sentence）定义：用于表达命令、请求、劝告、警告、禁止等的句子叫做祈使句，祈使句最常用于表达命令，因此在学校文法中也常称为命令句。祈使句因对象（即主语）是第二人称，所以通常都省略。祈使句的动词都为一般现在时，句末则使用句号或感叹号来表示结束。祈使句的肯定句：行为动词原形+其他Eg:Go and wash your hands.去洗你的手。命令 Watch your steps.走路小心。警告 Look out！Danger！小心！危险！强烈警告，已如感叹句 No Swimming.禁止游泳。禁止其中，以Let开头的祈使句，Let后宾语是是第一人称时，否定形式是在宾语后加not,Eg:Lets not do that again.我们别再那样做了。 如果Let 后面宾语是第三人称，否定形式是在Let前加助动词Dont,Eg:Dont let them come in.别让他们进来。 祈使句的否定通常使用“Dont ”，Dont+动词原形（行为动词/be动词）+其他 No+ V-ing No parking!不准停车Eg: Dont let the dog in.不要让那只狗进来。 Dont touch, please.请不要用手触摸。【典型例题】1_late for class!A.Dont B.Not be C.Dont be2Run in the hallways.（改为否定句）_ _in the hallways.3英译汉：别在马路上跑。_二、能力巩固1、They have rules in their class.
