Every human being, no matter what he is doing, gives off body heat. The usual problem is how to get rid of it. But the designers of the Johnstown campus of the University of Pittsburgh set themselves the opposite problem­—how to collect body heat. They have designed a collection system which uses not only body heat, but the heat given off by such objects as light bulbs（燈泡）and refrigerators as well. The system works so well that no fuel is needed to make the campus’ six buildings comfortable.

Some parts of most modern buildings—theaters and offices as well as classrooms—are more than sufficiently（足夠）heated by people and lights and sometimes must be air-conditioned even in winter. The technique of saving heat and redistributing it is called “heat recovery”. A few modern buildings recover heat, but the University’s system is the first to recover heat from buildings and reuse it in others.

Along the way, Pitt has learned a great deal about some of its producers. The harder a student studies the more heat his body gives off. Male students send out more heat than female students and the larger a student, the more heat he produces. It is tempting to conclude that the hottest prospect for the Johnstown campus would be a hard-working overweight male genius（天才）.

1. Which of the following is true of the heating system of the Johnstown campus? The heat is supplied by________.

A. human bodies, other heat sending objects, and fuel

B. both human bodies and other heat sending objects

C. both human bodies and fuel

D. human bodies

2. The technique of heat recovery is used________.

A. to produce a special form of air-conditioning

B. to provide heat for the hot water system

C. to find out the source of heat

D. to collect and reuse heat

3. Which of the following persons would produce the least amount of heat?

A. A thin male who studies hard.

B. A fat female who studies hard.

C. A fat male who does not study hard.

D. A thin female who does not study hard.

4. The words“the hottest prospect”refer to_______.

A. the person who suffers most from heat

B. the person who produces most heat

C. the person who uses most heat

D. the person who takes in heat

5. A good title for the passage would be_______.

A. MODERN BUILDING’S HEAT SYSTEM

B. A NEW HEAT RECOVERY SYSTEM IN PITTSBURGH

C. A STRANGE OBJECT IN HEATING SYSTEM

D. RECOVERY OF BODY’S HEAT

Every human being has a unique(唯一的，獨特的)arrangement of the skin on his fingers and this arrangement is unchangeable. Scientists and experts have proved the uniqueness of finger-prints and discovered that no exactly similar pattern is passed on from parents to children, though nobody knows why this is the case.

The ridge structure on a person’s fingers does not change with growth and is not affected by surface injuries. Burns, cuts and other damage to the outer part of the skin will be replaced in time by new one, which bears a reproduction of the original pattern. It is only when the inner skin is injured that the arrangement will be destroyed. Some criminals make use of this fact to remove their own finger-prints but this is a dangerous and rare step to take.

Finger-prints can be made very easily with printer’s ink. They can be recorded easily. With special methods, identification(辯認，鑒定)can be achieved successfully within a short time. Because of the simplicity and economy of this system, finger-prints have often been used as a method of solving criminal case. A suspected man may deny a charge but this may be in vain. His finger-prints can prove who he is even if his appearance has been changed by age or accident.

When a suspect leaves finger-prints behind at the scene of a crime, they are difficult to detect with the naked eye. Special techniques are used to “develop” them. Some of the marks found are incomplete but identification is possible if a print of a quarter of an inch square can be obtained.

Scientists and experts have proved that the pattern of a human being’s finger skin ________.

A. is similar to his mother’s

B. is valuable to himself only

C. is like that of others with the same type of blood

D. is different from that of all others

If your fingers are wounded by knife, fire or other means, the structure of skin will ________.

A. be changed partly                                  B. be replaced by a different one

C. be the same when the wound is recovered      D. become ugly

Some criminals remove their own finger-prints by ________.

A. using printer’s ink      B. injuring the inner skin

C. damaging the outer skin   D. damaging the colour

Finger-prints have often been used as a method of solving criminal case because it ________.

A. is complicated but reliable   B. is simple and not expensive

C. is expensive but easy to do   D. can bring a lot of money

The meaning of the word “volunteer” may be a little different in different countries, but it usually means “one who offers his or her services．” There are many different ways in which people can volunteer, such as taking care of sick people, working in homes for homeless children, and picking up garbage from beaches and parks．Volunteers may work within their own countries or in other countries．They are often people with a strong wish to help those who are less fortunate than themselves．Volunteers don’t expect any kind of pay．

   At the root of volunteering is the idea that one person may have the ability to offer services that can help other people．Tracy, a good friend of mine, however, recently came back from India with a new idea of what being a volunteer means．She worked for two and a half weeks in one of Mother Teresa’s homes in Calcutta．The following is her story．

   “I was asked to work in a home for sick people．I helped wash clothes and sheets, and pass out lunch．I also fed the people who were too weak to feed themselves and tried to cheer them up．I felt it was better to share with them than to think that I have helped them．To be honest, I don’t think I was helping very much．It was then that I realized that I had not really come to help, but to learn about and experience another culture that helped improve my own understanding of life and the world．”
