Unit 4 Don’t eat in class.

SectionA

‘’

1.Don’t arrive late for class。上课不要迟到。

【知识详解 】①这句是祈使句的否定形式（Don’t +行为动词原形+其他),用于表达命令、请求等。祈使句可以表达说话人的意愿、请求、叮嘱、号召、命令或建议，它的主语（听话人）通常省略，谓语动词用原形,句子末尾用感叹号或句号.

例如：Don’t throw the ball like that。不要那样扔球.

②arrive late for与be late for同义,都表示“做某事迟到”.arrive late for侧重到达的时间晚，be late for侧重状态。

例如：Don’t arrive late for the meeting next time.=Don’t be late for the meeting next time。下次开会别迟到了.

③arrive不及物动词,意为“到达，抵达，来到"，不能直接跟名词作宾语，但可以接介词at或in，构成短语“arrive at/in+地点（at+小地方,arrive at the bus stop；in+大地方,arrive in Beijing）"，意为“到达……”；arrive后若是here，there，home等地点副词，则不需要加in或at等介词（arrive here/there/home)。

例如：He arrives at the bus stop at 8 o’clock every morning。他每天早晨8点到达公共汽车站。

When did you arrive in Beijing？你什么时候到北京的？

I arrive home at 4：00 in the afternoon。我下午4点钟到家.

【辨析】arrive、reach与get

—-When will the plane     Shanghai?

—-Sorry，I don’t know。

1. get   B.arrive at   C.reach

2. You must be on time.你一定要守时(你必须准时）

【知识详解】①must为情态动词，意为“必须，务必，一定”。情态动词不能单独作谓语动词，必须和动词原形一起构成谓语。

例如：You must read a book before you watch TV.

【拓展记忆】①must用于否定句时，mustn’t意为“千万不要，禁止"，而不表示“不必"。例如：You mustn’t be late for school.你千万不要上学迟到。②以must开头的一般疑问句，若作否定回答，可以用needn’t或don't have to，但不能用mustn't（一定不，不允许，不得。如:You mustn’t smoke in the office。你不得在办公室吸烟。)。

例如：—-Must I clean all the rooms?我必须打扫所有的房间吗？——No，you needn’t/don’t have to.不，你不必。［该句肯定回答：Yes,you must.是的,你必须(马上打扫）。]

②on time为固定短语，表示“按时；准时”,指按规定的时间或指定的时间做某事；而in time表示“及时”，指不迟到或在规定时间之前或接近所规定的时间做某事。

例如：We must arrive there on time.我们必须按时到达那里。

1.We          be carefull when we're walking across the road。There're too many cars now.

A.can     B.may      C.must     D.could

3. Don’t run in the hallways。不要在走廊里奔跑.

此句是祈使句的否定形式。祈使句是表示请求、命令、劝说、建议等语气的句子.在祈使句中，通常省略第二人称主语you。其肯定句式以动词原形开头，否定句式是在动词原形前加don’t。常在句首或句末加please以示礼貌。句末用please时,前面通常加逗号。

例如：Stop talking!停止谈话！Don’t play football in the street.不要在街上踢足球。

Come in ，please。/Please come in.请进来。

Please don’t stand up./Don’t stand up,please.请不要站起来。

4. Don’t listen to music in class.不要在课堂上听音乐。

【知识点详解 】①listen to music意为“听音乐”，其中listen为不及物动词，其后接宾语时,要加介词to。例如：Listen!The girl is singing。听！那个女孩正在唱歌。

【辨析】liaten与hear

5.Don’t fight。不要打架

【知识详解 】①fight此处作动词，意为“打架,争吵”，过去式是fought。

例如：Stop fighting，you two。你们两个人，别打了！

②fight还可作名词，意为“打架，战斗（力),斗志”，have a fight打架，have a fight with sb.和……打架，win/ lose a fight赢得/失去战斗.

例如:Tom had a fight with his brother yesterday.昨天汤姆和他弟弟打架了.

They had a fight last night。昨晚他们打了一架。

【辨析】fight for，fight about，fight with与fight against

例句：They fight for their country.他们为他们的祖国而战斗。

The two boys often fight about the toys。这两个男孩常因这些玩具而争吵。

6.wear a hat戴帽子。

【知识点详解】wear为及物动词（同音词where；动词形式wear-wears-wearing—wore）,意为“穿着；戴着"，表示状态。

例如：He wears a black T-shirt.他穿着一件黑色的T恤衫。

She likes wearing a red hat.她喜欢戴一顶红色的帽子。

【辨析】put on意为“穿上；戴上”，强调穿、戴的动作；“be in+颜色/衣服”意为“穿着……颜色的衣服”，表示穿的状态（wear）。

例如：It's cold outside.Put on your coat，please。外面冷，请穿上你的外套。

She is in red=She wears a red chothes.她穿着红色的衣服。
