Thanks for your last letter. You want to know the rules in our school. Now let me tell you about them.
We can’t arrive late for class. We can’t talk loudly in class. We should keep quiet. When we
meet our teachers on our way, we should say hello to them. We can’t eat or drink in class, and we
can’t listen to music or play games in class.
I think we have too many rules. What about yours? Please write and tell me. Yours
五、重难点解析：
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。
（1）结构：主语＋have to＋动词原形＋其他
（一般现在时，主语是第三人称单数时，用has to；句子是过去时，用had to.）如： 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。 （2）否定形式：主语＋don't have to＋动词原形＋其他
（一般现在时，主语是第三人称单数时，用doesn't have to. 句子是过去时，用didn't have to）
如：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。 （3）疑问句：Do （Does或Did）＋主语＋have to ＋动词原形＋其他 如：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？ must 主观
2. hear，listen和sound都有\听\的意思，但三者是有区别的。 （1）hear\听说\，侧重于\听\的内容
I'm sorry to hear that you are ill. 听说你生病了，我很难过。
I never heard such an interesting story. 我从来没听过这么有趣的一个故事。
（2）listen\听\侧重于\听\这一动作。Listen to me carefully. 认真听我说。 The children like to listen to music. 孩子们喜欢听音乐。
（3）sound\听起来\，它是系动词，后面接形容词等。That sounds great. 那听起来真不错。 It sounds like fun. 听起来挺有趣。
3. be in bed \在床上、卧床\和bed之间不能用冠词，bed也不用复数。 He is in bed for 10 years. 他卧床10年了。Dave has to be in bed early every night.大卫每晚必须很早睡觉。
4. arrive late for 与be late for 意思相近，\迟到\（be）late for school. 上学别迟到。I arrived （was）late for the meeting yesterday. 我昨天开会迟到了。
5. No talking ! \禁止交谈！\后面加上名词或动名词（doing）也表示不要做某事。与don't +do的用法相似。No wet umbrellas! / Don't put wet umbrellas here! 禁止放湿雨伞！
No food! Don't eat food here! 禁止吃食物！No smoking! Don't smoke here! 禁止吸烟！
六、语法（祈使句）
祈使句是用来表示请求、命令、叮嘱、号召或者劝告等的句子，这类句子的主语常是第二人称you，也就是听话者，因而you常省去了。祈使句的开头是动词原形。
如：Look out! 小心！Wait here for me! 在这等我！ Be sure to come here on time! 务必准时来到这里！
祈使句的否定形式多以do not（常缩写成don't）开头，再加上动词原形。 Don't arrive late for school. 上学别迟到。 Don't fight! 别打架！
Don't look out of the window. 不要向窗外看。
