科学与技术的另一个区别在于其各自的发展进程。科学的发展排除了人的因素。在试图以最精确、最可靠的方式理解宇宙、了解真理的过程中，科学家不可顾及他们本人或他人的好恶以及公众对事物合理性的构想。科学家的发现可能使人震惊或恼火——如达尔文的进化论。而即使是令人不快的发现也很可能具有实用价值。而且，我们还有拒绝相信的选择!不过，技术就不同了。我们无法不听在头顶掠过的超音速飞机发出的轰鸣，我们无法拒绝呼吸污染了的空气。与科学不同，技术上的进步必须受制于我们，而不是相反。技术的正当目的就是服务于人——是所有人，而不仅仅是某些人；未来一代的人，而不仅仅是那些希望马上从中获益的人。
    我们熟知技术的弊病。许多人一般谴责技术本身扩散污染，消耗能源，甚至导致社会腐败——连技术的承诺也失色了。这承诺就是一个更干净、更健康的世界。如果科学技术的善用不能引出更美好的世界，那还有什么可以呢?
About Friendship
     Friendship is a kind of human relations. It is a human instinct to make friends.When in trouble, we
need friends to offer us help, support and encouragement. With success achieved, we also need friends to share our joys.
     Friendship is also one of the greatest pleasures that we can enjoy. It implies loyalty, cordiality, sympathy, affection,and readiness to help. No man can make the most of his life without carefully and conscientiously striving to win the right kind of friends as he goes along.
     Knowing how valuable friendship is, we should be very careful in making friends. Real friends are those who have good character, superior ability and kindness of heart. Real friends can share all our sorrows and double all our joys.While making friends, we should take care to select those who have such fine qualities. Then we should treat our friends with courtesy, be careful not to interfere unreasonably with them,and not to ridicule their proceedings. We should forgive their failures and do our best to help them. In short, when we have established friendship, we ought to cherish and treasure it by means of words and deeds. Only thus, can we develop real friendship and keep the sacred lamp of friendship burning all our life.

得最大益处。

Stress and Relaxation
      As the pace of life continues to increase, we are fast losing the art of relaxation.Once you are in the habit of rushing through life, being on the go from morning till night,it is hard to slow down. But
relaxation is essential for a healthy mind and body.
      Stress is a natural part of everyday life and there is no way to avoid it. In fact, it is not the bad thing as it is often supposed to be. A certain amount of stress is vital to provide motivation and give purpose to life. It is only when the stress gets out of control can it lead to poor performance and iii
health.
      The amount of stress a person can withstand depends very much on the individual. Some people are not afraid of stress, and such characters are obviously prime material for managerial responsibilities. Others lose heart at the first signs of unusual difficulties. When exposed to stress, in whatever form, we react both chemically and physically. In fact, we make a choice between "flight or fight"and in more primitive days the choices made the difference between life or death.The crises we meet today are unlikely to be so extreme, but however little the stress, it involves the same response. It is when such a reaction lasts long, through continued exposure to stress, that health becomes endangered. Such serious conditions as high blood pressure and heart diseases have established links with stress. Since we cannot remove stress from our lives (it would be unwise to do so even if we could), we need to find ways to deal with it.
压力与松弛
    随着生活节奏的持续加快，我们正在迅速地丧失放松的本领。你一旦养成了快节奏的生活习惯，从早到晚忙个不停，要想放慢节奏就不是件容易的事儿。可是松弛对一个人的身心健康至关重要。
    压力是日常生活的一个自然组成部分，无法逃避。事实上，压力并不像人们通常想象的那样是件坏事。一定的压力对于激发动力、赋予人生以目标是至关重要的。只有
在压力过大时才会导致表现失常，健康恶化。liuxuepaper.com
