The doctor asked Tom about his daily habits. After hearing about his computer game addiction, the doctor said, "The problem is your eyes and your lifestyle. You must limit your time on the computer. You should do more outdoor activities. Also, you need to get enough sleep."

第三部分：参考答案与解析

单项选择

1. A，考查固定搭配 "What's the matter with...?" (……怎么了？)。
2. C，考查请求的回应，根据 "I'm busy right now" (我现在很忙)，应表示委婉拒绝，"Sorry, I can't" 最合适。
3. D，考查短语动词 "lie down" (躺下休息)。
4. A，考查情态动词的用法，根据 "It's bad for your teeth" (对你的牙齿不好)，应用 "shouldn't" (不应该) 提出建议。
5. A，考查过去进行时，主句 "the phone rang" 是过去发生的短暂动作，从句 "my mother...dinner" 是在过去那个时间点正在进行的动作，故用过去进行时 "was cooking"。
6. A，考查一般过去时，句中有明确的过去时间状语 "when he was five"，描述过去发生并已完成的动作，用一般过去时 "taught"。
7. B，考查 how 引导的特殊疑问词，根据回答 "For about five years" (大约五年了)，询问持续的时间，用 "How long"。
8. A，考查连词。"so...that..." (…以至于……) 结构，"as soon as" (一……就……) 符合语境，句意：这个小男孩一躺在床上就睡着了，累极了。
9. A，考查动词短语，根据语境 "borrow some money" (借一些钱)，"give out" (分发) 不符合逻辑，此处应为 "borrow"，但选项中没有，最接近且符合 "give" 相关的短语是 "give out"，但意思不符。（注：此题选项可能设计有误，应为 "lend"），如果选项中有 "lend"，则为最佳答案，如果没有，"give back" (归还) 也有可能，但 "lend" 最准确，我们假设题目有误，最佳答案是 lend。
10. C，考查非谓语动词，want sb. to do sth. (想要某人做某事)，故用 "to study"。

Dear Tom,

I'm sorry to hear that you are having trouble sleeping because of study pressure. I think you should try to relax.

First, you shouldn't study too late at night. It's important to get enough sleep. Second, you could listen to some soft music or take a walk before going to bed. This can help you relax.

I hope you will feel better soon. Please take care of yourself.

Yours, Li Hua

第四部分：复习与应试技巧

1. 回归课本，夯实基础：把课本上的单词、短语和重点句型再过一遍，确保烂熟于心，很多题目都源于课本。
2. 整理错题，查漏补缺：平时作业和练习中的错题是最好的复习资料，把错题整理到错题本上，分析错误原因，是单词不认识？语法没掌握？还是审题不清？
3. 专项练习，攻克语法：针对自己薄弱的语法点（如现在完成时、过去进行时）进行专项练习，多做不同类型的题目，加深理解。
4. 坚持阅读，培养语感：每天坚持读一篇短文，不仅能巩固词汇和语法，还能提高阅读速度和理解能力。
5. 模拟考试，把握时间：在考前找一套完整的模拟卷，在规定时间内完成，锻炼自己的应试能力和时间分配能力。
6. 书写工整，卷面整洁：在书面表达中，清晰的书写和整洁的卷面会给阅卷老师留下好印象，有助于获得高分。
