题目：
进入高三后，紧张的备考复习开始了，越来越多的同学不再参加体育锻炼，有的人认为体育锻炼不重要，也有的人因为学习太累而不愿意再锻炼。下周你们班将要举行一次班会，号召大家踊跃参与体育锻炼。假如你是班长，请写一份演讲稿，准备届时发言。
谢啦...

Good afternoon everyone.

I feel that it is a responsibility to be here and give this speech. I have found that fewer and fewer of our classmates have been doing sports ever since the beginning of this term. Maybe each of them has a different reason. But I believe that doing exercise is more important, for the following reasons.

Firstly, the busier we are with our study, the more necessary it is for us to take physical exercise. Playing sports can give our brains a chance to get relaxed, which will allow us to study more efficiently. Secondly, doing sports every day, such as playing ping-pong or basketball, can greatly reduce the possibility of getting ill. That means we will have more time for study. What’s more, everybody wants to have an admirable figure together with a nice face, right? We can achieve this only if we spend a certain amount of time every day sweating on the playground.

As graduation is drawing near, it will not be long before we say good-bye to each other, so let’s spare some time to play together.

Don’t hesitate, take action and let’s meet on the playground．That’s all. Thank you.
