[多项选择]凡事应该适度。适度是最安全的。以学生生活为例，有些学生学习太努力，而玩得太少；还有些学生玩得太多，而学习得太少。前者由于缺少体育锻炼弄坏了身体，后者玩得太多而损坏了智力。
在饮食方面，也必须要适度。不要吃得太多或太少，吃得太多你会生病，而吃得太少你会虚弱。
能取得进步的人是那些思想既不太保守而又不太激进的人。太保守的人，他裹足不前，而太激进的人，他就东闯西闯没有明确的目标。心胸宽的人总是在合理的范围内活动。在生活中，无论什么样的活动，适度是通向享受幸福的最好途径之一。

参考答案:One should be moderate in all things. Moderation is always the safest way. Let’s take the student life for instance. There are some who study too hard and play too little, and there are others who plays too much and study too little. On the one hand, this is harmful to the body through lack of exercise; and, on the other hand, to the mind through much play.
In the matter of eating, one also should be moderate. Do not eat too much or too little. Too much eating will make you sick, while too little eating will make you weak.
The man of progress is he who is neither too conservative in thought nor too radical. In the former case he does not move, and in the latter he is restless—that is, without a definite aim. The broad-minded man is he who likes moves within the orbit of reasonableness. Whether in any activities in life, moderation is one of the best way to enjoy real happiness.
