第三部分：范文示例

这里提供三种最常见的作文类型。

范文1：建议信

给你的朋友李华写一封信，建议他如何保持健康。**

Dear Li Hua,

I heard that you haven't been feeling well recently. I'm worried about you. I think it's very important to keep healthy, so I'm writing to give you some advice.

First, you should pay attention to your diet. It's better to eat more fruit and vegetables, which are good for your health. Try to have a balanced diet. At the same time, you should eat less junk food like hamburgers and candy because they contain too much sugar and fat.

Second, doing enough exercise is also necessary. You can take a walk after dinner or play basketball with your friends for half an hour every day. This can help you build a strong body.

Finally, don't forget to get enough sleep. Going to bed early and getting up early is a good habit. It can help you feel energetic the next day.

I hope these suggestions will be helpful to you. If you follow them, I'm sure you will become much healthier soon.

Yours, Wang Ming

范文2：说明文 / 议论文

论健康的重要性以及如何保持健康。**

As we all know, health is the most important thing for us. Without good health, we can't study or work well. So, how can we keep healthy? Here are some of my ideas.

First, a healthy diet is the key. We should eat more healthy food, like fresh vegetables, fruit, and milk. They give us energy and vitamins. We should also eat less junk food because it's bad for our health.

Second, we need to exercise often. Doing sports can make us strong. We can run, swim, or play ball games. It's a good idea to exercise for at least 30 minutes every day. This can help us stay in good shape.

Third, we must have good living habits. We should get enough sleep, about eight hours a night. We shouldn't stay up late. Also, we should learn to relax ourselves when we feel stressed.

In a word, a healthy lifestyle is necessary for everyone. If we eat healthily, exercise often and have good habits, we will surely have a healthy and happy life.

范文3：记叙文

记一次你和家人一起保持健康的一天。**

My family and I have a very healthy lifestyle. Last Sunday was a perfect example of how we keep fit.

In the morning, my father and I got up early and went to the park. We did some running and then played badminton for about an hour. We were sweating a lot, but we felt very energetic. My mother usually stays at home and does some yoga to relax.

For breakfast, we had some milk, boiled eggs, and fresh fruit. My mother always says a good breakfast is the start of a healthy day. We never eat fried food for breakfast.

In the afternoon, we all went to the supermarket together. Instead of buying snacks and soda, we bought a lot of vegetables, some fish, and some chicken. My mother cooked a delicious and healthy dinner for us. We talked and laughed happily while eating.

After dinner, we took a walk in our neighborhood. It was a great way to digest the food and relax before going to bed.

I think a healthy lifestyle makes our family closer and happier. I love my healthy family life!

2. 列提纲：动笔前，先用简单的词语或句子列出文章的结构（开头、中间要点、,这样思路会更清晰。
3. 善用连接词：使用 First, Second, Finally (其次，, Besides (, However (, So ( 等词,让文章逻辑更连贯。
4. 主语要明确：通常用 We (我们) 或 You (你) 来泛指大家，比用 People (人们) 更自然。
5. 检查语法：写完后，检查一下主谓一致、时态、单复数等基本语法是否正确，确保文章没有拼写错误。 对你有帮助！加油！
