挑战话题作文
参考答案：
Dear LiLei,
I’m sorry to hear that you are often ill. Now let me give some
advice.
You should keep healthy eating habits.
need to do sth:需要做某事, 用must语气比较强硬。
两句话作为第一段，注意advice是不可数名词
For example, you had better eat more vegetables and fruit. On the
other hand, you had better not eat junk food.
最好要吃和最好不要吃，分别用上had better和had better not,
中间再用上on the other hand这个连词.
Second, you need to go to bed and get up early. You must wash hands
before meals.
此句作为饮食方面的中心句，用上should。
How to keep healthy
Third, doing exercise is good for your health, too. You can play sports twice a week.
Finally, happiness is important to you. So try to be happy every day.
doing exercise 是动名词当主语，后面扩写一句具体的运动建议。
happiness 是名词当主语，不能用形容词的happy; 后面扩写一句
具体的快乐建议。
I hope you can live a healthy life.
最后一段用一句话表达祝愿.
