新目标八年级英语上册unit5作文
答案
In the 10 minute breaks between classes,some students choose to stay indoors,sitting at their desks chatting with their classmates or dozing off.Others,however,prefer to go outdoors to play actively for a while.I am in favor of the latter,of course.The following are my reasons.
On the one hand,having been concentrating on what the teacher says and what they do in class makes both our brains and eyes tired.Playing actively outdoors provides our brains and eyes with entirely different kinds of activities,thus enabling them to have a complete rest.On the other hand,with so many students sitting in the classroom for such a long time,the air inside is certainly not fresh,and sometimes can even be foul which is certainly bad to our health.Playing actively outdoors enables us to breathe a lot of fresh air,thus making us refreshed and re energized very quickly.The last reason is that sitting at the desk for hours on end can be bad to our body.Playing actively outdoors makes us strong and fit.
Therefore,it is strongly recommended that those who stay indoors go out to play actively in the 10 minute breaks between classes.It will surely make you healthy and wise.
