Writing a sports paper, as you said, can be demonstrated from the following aspects.

1, the body is the capital of the revolution, and only a good body can do other work. This shows that a good body needs exercise, and exercise must be persisted. )

2. Efficiency of work. Good health can ensure the efficiency and quality of work. This can also explain the importance of exercise. & gt)

What's more, if we don't know how to exercise and only know how to earn money, it is equivalent to changing our lives for money when we are young. When we are old and in poor health, we will exchange money for life. At that time, I was lying in bed in pain, but I didn't exercise at ordinary times. Well, stick to it for an hour every day, and when I form a good habit, I won't feel bothered anymore. )

I think it is enough to demonstrate from these three aspects. Generally speaking, it is enough to find three or four arguments in an argumentative essay. Each argument is about 200 words. To sum up, 700 words is more than enough. .

I hope I can help you. . .
