优秀范文

My Good Habits**

As a ninth-grade student, I believe that good habits are the key to a successful and healthy life. I'm proud to say that I have formed several good habits that benefit me a lot.

Firstly, I have a balanced diet. For breakfast, I always have some milk and eggs to get enough energy. I eat plenty of fresh vegetables and fruits at lunch and dinner. I rarely eat junk food because it's high in sugar and fat, which is bad for my health. Secondly, I never stay up late. I make sure I get at least eight hours of sleep every night. This helps me stay energetic and focused in class the next day. Thirdly, I have a habit of reading. I spend about half an hour reading English or Chinese novels before going to sleep. Reading not only enriches my knowledge but also improves my writing skills.

In conclusion, these good habits have become an important part of my life. They keep me healthy and help me study better. I will stick to them and try to develop more good habits in the future.

Exercising can make us strong and relaxed. Third, we must get enough sleep. It's not good to stay up late to watch TV or play computer games. A good rest helps us study better.

3. 结构清晰: 采用“总-分-总”的结构，即开头点题，中间分点论述，结尾总结，使用 First, Second, Third 或 For one thing, For another 等连接词，让文章更有条理。
