作文预测与范文
预测题目： 假设你叫李华，你英国笔友Mike在邮件中说他觉得中文很难学，总是记不住生词，感到沮丧。请你给他回一封邮件，分享你的英语学习经验，并给他一些学习中文的建议。
范文：
Dear Mike,
I'm sorry to hear that you're having trouble learning Chinese. Don't worry, it's common for language learners to face difficulties. I'd like to share my experience of learning English with you.
When I first started learning English, I also found it hard to remember new words. Then I tried many ways. For example, I often make word cards and stick them on my wall. I also listen to tapes every morning to improve my listening. The most effective way for me is to have conversations with my friends. We practice speaking after class, and it really helps. By doing this, I become more confident.
Maybe you can try some of these methods. You can watch Chinese videos or movies with subtitles. Asking your teacher for help is also a good idea. Most importantly, don't be afraid of making mistakes. The secret to language learning is to practice every day.
I believe you can make great progress if you keep trying.
Best wishes,
Li Hua

I know (that) he is a good teacher.（我知道他是个好老师。）
She said (that) she would come later.（她说她晚点会来。）
由 if 或 whether 引导的宾语从句：
功能： 表示一个“是否”的疑问（一般疑问句转变成的从句）。
例句：
I wonder if/whether it will rain tomorrow.（我想知道明天是否会下雨。）
He asked me if/whether I had finished my homework.（他问我是否完成了作业。）
区别： whether 常与 or not 连用，if 一般不行。
例句： I don't know whether he will come or not.（我不知道他是否会来。）
宾语从句的语序： 一律用陈述句语序（主语在前，谓语在后）。
错误： Can you tell me where is the station
正确： Can you tell me where the station is （你能告诉我车站在哪吗？）
宾语从句的时态：
主句是现在时（如 I think），从句可根据需要用各种时态。
例句： I believe he is right. / I believe he was right.（我相信他是对的。/ 我相信他当时是对的。）
主句是过去时（如 I said），从句一般要用相应的过去时态。
例句： He said he was tired.（他说他累了。）
作文预测与范文
预测题目： 向外国朋友介绍一个中国传统节日（如中秋节、春节等）。内容包括节日的时间、人们通常进行的活动、以及这个节日的意义。 范文：
The Mid-Autumn Festival The Mid-Autumn Festival is one of the most traditional Chinese festivals. It falls on the 15th day of the 8th lunar month.
On this day, families get together to celebrate. They share a big meal and then enjoy the full moon. The most important food is mooncakes. They are round and look like the full moon, which stands for family reunion. People also tell the story of Chang'e, a story that reminds us of the importance of home and family.
I think the Mid-Autumn Festival is a warm and meaningful festival because it helps us to show our love to our families. I can't wait to celebrate it with my grandparents this year.

例句：
I don't know what I should do. -> I don't know what to do.

礼貌的询问方式：
在问路或询问信息时，为了显得更礼貌，常用以下句型开头：

作文预测与范文
预测题目： 你们班正在进行一场关于"中学生是否应该做兼职"的讨论。请写一篇短文，陈述你的观点并说明理由。
范文：
Should Teenagers Have Part-time Jobs
In our class, we had a discussion on whether teenagers should be allowed to have part-time jobs. I think it is a good idea. First, having a part-time job can teach us how to manage our time and money. It is a useful life skill. Second, we can learn how to deal with different people and become more independent.
Of course, study is the most important thing for us. So, the job should not get in the way of our schoolwork. Parents should be strict with us and make sure we are safe. Only then can a part-time job be a valuable experience for us.
