Have you ever had headache during a test? Have you ever been too concerned about something that you even can’t sleep at night? If so, then you know that stress is. Too much stress can result in angry, depression and other related problems, which we need to take them seriously.

However, not all stress was harmful to you. Some kinds of stress can help you getting things done better, like when you are running towards the finishing line or when you are asking to deliver a speech to your class. Stress sometimes can push you to make full preparations for a test.

The best approach of reducing stress is to have a balanced life. If you get enough sleep, eat proper, take more exercise and have enough fun time, you might feel less stressed.

I am interested at swimming very much. At first, I went swimming just to keep health. Now my dream was to swim for my country in the Olympics. Though practicing in the pool is very bored, but I still work very hard in order to realize my dream. Because my hard work, I have already come first in much important competitions. In the competitions, I’ve made a lot of friend and we’re very close. It’s much easier to have friends which are swimmers because they also have to get up early to practice like you and they understand this kind of life.

My school held an excited sports meet recently. During the event, enjoyment sweep over us all. When the relay race was under the way, the athletes ran fast to pass other competitor. It kept the rest of us on the edge of their seats. “Hold on! You can make that!” the students yelled. In the distance running competition, all people cheered and clapped with runners who passed by. At the same time, a volunteer team of over 400 students were divided several groups to help teachers and athletes. Join a sports meet is a good way to raise your enthusiasm for learning. Sports can help you forget all your troubles and face school and life more positive.
