七．巩固练习参考答案：
Dear friends
As we all know, we are what we eat. Therefore, it's very important for us to form healthy eating habits. However，bad eating habits are still very common among us students. Some don't have breakfast. Some prefer snacks. Some are particular about food and some eat or drink too much.
To keep fit, we should have various healthy diets, which generally include proper amounts of fish, meat, vegetables, fruit as well as staple food. Besides, we'd better take meals at a regular time and eat a proper amount of food each time.
From my point of view, we should try to develop healthy eating habits. Only in this way can we have enough energy to study.
That's all. Thank you!
