What will people die of 100 years from now? If you think that is a simple question, you have not been paying attention to the revolution that is taking place in bio-technology(生物技术). With the help of new medicine, the human body will last a very long time. Death will come mainly from accidents, murder and war. Today's leading killers, such as heart diseases, cancer, and aging itself, will become distant memory.
In discussion of technological changes, the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live? Human brains were known to decide the final death. Cells(细胞) are the basic units of all living things, and until recently, scientists were sure that the life of cells could not go much beyond 120 years because the basic materials of cells, such as those of brain cells, would not last forever. But the upper limits will be broken by new medicine. Sometime between 2050 and 2100, medicine will have advanced to the point at which every 10 years or so, people will be able to take medicine to repair their organs(器官). The medicine, made up of the basic building materials of life, will build new brain cells, heart cells, and so on---in much the same way our bodies make new skin cells to take the place of old ones.
It is exciting to imagine that the advance in technology may be changing the most basic conditional human existence, but many technical problems still must be cleared up on the way to this wonderful future.

Watercolor（水彩画） is the oldest paints known. It dates back to the early cave men. They discovered that they could mix the natural colors found in the earth with water. In this way they could add lifelike qualities to drawings of animals and other figures on the wall of caves.
Fresco（壁画）, one of the greatest art forms, is done with watercolor, it is created by mixing paints and water and applying these to wet plaster（灰泥）. Of the thousands of people who stand under Michelangelos’ works in the Sistine Chapel, very few know they are looking at perhaps the greatest watercolor painting in the world.
The invention of oil painting by the Glemish masters in the fifteenth century made fresco painting go downhill, and for the next several centuries watercolor was used mainly for doing sketches（素描） or as tool for study. It was not until the eighteenth and nineteenth centuries that English painters put back watercolor as a serious art form. The English have widely-known love for the outdoors and also for small, private pictures. The softness of watercolor had a strong attraction for them.
The popularity of watercolor continued to grow until the twentieth century. The United States took the place of England and became the center of watercolor. It produced such well-known watercolor artists as Thomas Eakins and Andrew Wyeth.

Since we are social beings, the quality of our lives depends in large measure on our interpersonal relationships. One strength of the human condition is our possibility to give and receive support from one another under stressful conditions. Social support makes up of the exchange of resources among people based on their interpersonal ties. Those of us with strong support systems appear better able to deal with major life changes and daily problems. People with strong social ties live longer and have better health than those without such ties. Studies over types of illnesses, from depression(沮丧) to heart disease, show that the presence of social support helps people defend themselves against illness, and the absence of such support makes poor health more likely.
Social support cushions stress in a number of ways. First, friends, relatives and co-workers may let us know that they value us. Our self-respect is strengthened when we feel accepted by others in spite of our faults and difficulties. Second, other people often provide us with informational support. They help us to define and understand our problems and find solutions to them. Third, we typically find social companionship supportive. Taking part in free-time activities with others helps us to meet our social needs while at the same time distracting (转移注意力) us from our worries and troubles. Finally, other people may give us instrumental support money aid, material resources, and needed services - that reduces stress by helping us resolve and deal with our problems.
1. Interpersonal relationships are important because they can ________
A. make people live more easily
B. smooth away daily problems
C. deal with life changes
D. cure types of illnesses
