英语作文：阳光体育活动！

Good morning everyone:
Today I’d like to give a speech about the importance and meaning of sports and show some of my ideas on whether students in senior high school, grade three should take physical exercises for an hour everyday.
There is a saying that if you can take physical exercises for an hour everyday, you will be able to work in good health for fifty year and live happily for a whole life. That is true. Sports not only ensure us good health, but also bring happiness. It is said by neurochemist that doing sports can make body produce some chemical substance entering your blood which with the circulation reaches your nervous system and makes you feel excited. As to it is good for our health, it is obvious. Everyone knows life exists in action. Physical advisor says that sports can improve the function of lungs and heart, and also make your immune system work better to protect your body away from diseases.
As we all know that students of senior high school, grade three is very busy with their study bearing great pressure. However, they also should find time to do physical exercises. The sports are not only a relaxation for your brain but also a refreshant for your mind. After hours after hours of hard work, you may feel tired and your brain may work more slowly, then if you stay there to study, you may lose efficiency. Thus why don’t go out of the classroom and breathe the fresh air in the playground. Why don’t choose your favorite sport to limber up your muscles and joints and be released from the anxiety and burden of your study. After that as more oxygen absorbed into your brain and much sweater going out of your body, you can restart your study with more energy.
All above is my opinion, I cordially hope you join us-sunshine sports-make yourselves more healthy and enjoy yourselves in your life. Remember: don’t let college entrance examination make your life monotonous and dull without any variation.
