Unit - 4 - Dont - eat - in - class知识点解析及练习题

Unit 4 Don’t eat in class

一、知识点解析�� 1.Don’t fight.不要打架。

fight作动词，意为“打架、打仗”。 ●fight with sb“和…打架”，“同…（并肩）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 战斗”，后只接表示人或国家的名词。 Eg:Don’t 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to

Eg: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】

umbrellas here! 禁止放湿雨伞��

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 to��

Eg:We have to wear sneakers for gym class.

●一般现在时:主语是第三人称单数时用doesn't have to,其它时候用don't have to. Eg:Nick doesn't have to wear a uniform. 尼克不必穿制服。 We didn't 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 don't. 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needn’（不必要）t，不用mustn’（不允许）t，mustn’t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 needn’t.不，你不需要。 You mustn’t park your car here.你的车不允许停在这儿。 【典型例题】 It’s very warm outside.You ________wear the

4. 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

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:Let’s 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Don’t, Eg:Don’t let them come in.别让他们进来。 ● 祈使句的否定通常使用“Don't …”，Don't+动词原形（行为动词/be动词）+其他 No+ V-ing No parking!不准停车 Eg: Don't let the dog in.不要让那只狗进来。 Don't touch, please.请不要用手触摸。。 【典型例题】
