The idea of progress started to flower in the 17th century． At that time， many wise thinkers believed that man liberated（解放） by reason would rise to greater heights of achievement． The many expressions of human nature would be the engines of progress： language， business， science， and moral sensibility （道德感）． Unfortunately， most of those engines have failed to bring the desired human progress．

The modern age has belonged to material progress and its main source has been science． Science gives people huge power to change the world． But can people be trusted to use it always for good？ Think of biotechnology and information technology． And it is not just that scientific progress does not deliver the emotional good． People also fear that mankind is failing to manage science properly． The forests are disappearing； the ice is melting； privacy is leaking； life is becoming a depressing march in an ugly world．

The point is not that science is harmful， but that scientific progress needs to be mapped tidily onto human progress． That relies on moral sensibility in its widest sense． This liberal force offers hope for a better future． The very idea of moral sensibility probably sounds out﹣of﹣date． Bur researchers find that people desire a sense of moral purpose which would give life dignity （尊严）． People want to determine how the world works， not always to be determined by it． Moral sensibility is why people will suffer from their beliefs， and why acts of noble self﹣sacrifice are so powerful．

It is admitted that our moral ideals will never be realized completely． But sometimes， however imperfectly， we can make progress． Human dignity requires the love of ideals for their own sake， but nothing requires that the love be returned．

Human progress is neither guaranteed nor hopeless． Instead， it is up to us．

Let’s get one thing straight: Studying sometimes is boring, right? But it is extremely necessary. After all, working through difficult material is a necessary part of the learning process—which leads to the obvious question: If I have to do it, is there at least a way to make it fun?

During Carol Dweck’s research for her book Mindset (思维模式): The New Psychology of Success, she found that students deal with learning in one of the two ways: they either look at difficult courses with a fixed mindset or with a growth mindset. Those with fixed mindsets believe that intelligence and talent are set in stone. For example, if they find a certain math problem difficult, they’d think, “I guess I’m just not a math person.” In contrast, students with growth mindsets are certain that they could change and grow in every area of their lives. If they come across a difficult problem, they will think, “I can get better at this...But I have to tough it out.”

Dweck found that most students start out pretty interested in a subject. Yet over the semester, something happens. Students with the fixed mindset may stay interested only when they do well right away. Those who find it difficult are likely to show a big drop in their interest and enjoyment. If it isn’t a testimony (证明) to their intelligence, they can’t enjoy it. In contrast, students with the growth mindset are able to continue to show the same high level of enjoyment even when they find the work very difficult. Difficulty and interest go hand in hand.

If you want to succeed and enjoy your studying, don’t think of your classes as a series of tests that show just how intelligent or unintelligent you are. Instead, think of them more as ongoing opportunities to learn and grow.

Scientists find that hard-working people live longer than average men and women. Career women are healthier than housewives. Evidence shows that the jobless are in poorer health than jobholders. An investigation shows that whenever the unemployment rate increases by 1%, the death rate increases by 2%. All this comes down to one point, work is helpful to health.

Why is work good for health? It is because work keeps people busy away from loneliness. Researches show that people feel unhappy, worried and lonely when they have nothing to do. Instead, the happiest are those who are busy. Many high achievers who love their careers feel that they are happiest when they are working hard. Work serves as a bridge between man and reality. By work people come into contact with each other. By collective activity they find friendship and warmth. This is helpful to health. The loss of work means the loss of everything. It affects man spiritually and makes him ill.

Besides, work gives one a sense of fulfillment and a sense of achievement. Work makes one feel his value and status in society. When a writer finishes his writing or a doctor successfully operates on a patient or a teacher sees his students grow, they are happy beyond words.

From the above we can come to the conclusion that the more you work the happier and healthier you will be. Let us work hard and study hard and live a happy and healthy life.
