Dear Dr Know, Help! There are too many rules in my life! Every morning, I have to make my bed before breakfast. I have to hurry to school because I can't be late for school. When I'm at school, I mustn't use my phone in class either. And I have to wear the uniform.
have to 表示客观需要(外部要求),must 表示主观必须(自己认为)。I have to wear the uniform. (校规要求) / I must study harder. (自己觉得必须)
either 表示「也」(否定句)
either 用于否定句末尾,表示「也」。肯定句用 too。I can't use my phone either. (也不能用手机) / I like it too. (我也喜欢)
After school, there are even more rules! I have to finish my homework first. I can only play basketball after I practise the piano. I can't hang out with my friends on weekdays. I know some rules are important, but this is awful! What can I do? Yours, Alice
after I practise the piano:我练完钢琴后。after 引导时间状语从句。主句和从句都用一般现在时表示规律性动作。
on weekdays 时间介词
on weekdays:在工作日。日期/星期前用 on。固定搭配:on Monday/Tuesday, on weekends。
Dear Alice, Yes, there are many rules in life! But they can help you to become a better person. You mustn't be late for class. That shows respect for your class and teacher. You can't use your phone in class because you need to focus on learning. You have to wear a uniform because it builds school spirit.
mustn't = must not,表示「禁止、绝不能」。You mustn't be late.(你绝不能迟到。)注意 don't have to(不必)与 mustn't(禁止)的区别。
because 说明原因
because you need to focus on learning:因为你需要专注学习。because 引导原因状语从句。注意 because 不与 so 连用。
You can also think about the things you can do! You can use your phone at home. You can relax after you finish your homework. And you can hang out with friends at weekends! I know it's hard, but rules can help to make the world better. Remember: No rules, no order! Best, Dr Know
第四段(Dr Know回信-下):博士引导Alice看到规则之外的自由——在家可用手机、周末可出去玩,总结:No rules, no order!
Section A 2a (Dialogue)
The New Student
新同学
Hi, I'm Anne. What's your name?
Hello! I'm Tom. It's my first day here.
It's nice to meet you, Tom! Is everything OK?
Well, I can't find my pencil box. I think it's in my locker.
Here, I can lend you my pen.
Thanks! Would you like a sweet?
No, thank you. We can't eat snacks in class.
Can we drink water?
Yes, of course.
Can we drink water?(许可)我们能喝水吗?I can lend you my pen.(能力)我能借给你笔。can 既可表示能力也可表示许可。
OK, thanks ... Oh! I'm sorry. I have to answer my phone.
Oh, but we mustn't bring our mobile phones to class.
We have to turn them off and keep them in our lockers. That's another rule.
OK! Thanks for telling me, Anne.
You're welcome, Tom.
