Scientists can learn about man by studying animals, such as mice, rats and monkeys. The scientists in a laboratory areexperimenting on mice and they are studying the relationship between diet and health. In this experiment, the scientists are studying the relationship between the amount of food the mice can eat and theirhealth. The mice are in three groups. All these groups are receiving the same healthy diet. But the amount of food that eachgroup is receiving is different. The first group is eating one cup of food each day, the second two cups, and the third threecups. After three years, the healthiest group is the one that is only eating one cup of food each day. The mice in this group arethinner than normal mice but they are more active. Most of the day, they are running, playing with one another, and using theequipment in their cages. Also, they are living longer. Mice usually live for two years, while most of the mice in this groupare still alive after three years. The second group of mice is of normal weight. They are healthy, too. They are active, but not as active as the thinnermice. But they are only living about two years. The last group of mice is receiving more food than the other two groups. Most of the day, these mice are eating orsleeping. They are not active. These mice are living longer than the scientists thought —about a year and a half, but they arenot healthy. The are sick more often than the other two groups. The first group is the thinnest mainly because

A.they run and play all day long

B.they eat only one cup of food a day

C.they live longer than the other groups

D.they are bored with the kind of food in the cup

There is no question that computer applications such as(71), electronic mail, and(72)publishing have changed the way people work. These computer applications have enhanced users capacity for communication and have improved their productivity. The success of these applications has prompted both vendors and researchers to continue to seek new ways to further advance the information technology revolution. Enter the latest innovation: networked(73)systems. They convey information in multiple(74): text, graphics, video, audio,(75), computer simulations, and so forth. Advocates of these systems argue that they are the next logical step in human communication; however, modifying our current networks to accommodate the variety of media will present significant technical difficulties.

A．word transaction

B．word processing

C．word disposal

D．word dealing

In addition to the established energy sources such as gas, coal, oil and nuclear, there are a number of other sources that we ought to consider. Two of these are hydroelectric and tidal power.

These two sources are【21】______ in that they are both renewable. 【22】______ , hydropower is more widely used than tidal. In【23】______ , a substantial amount of electricity is already produced in HEP (hydroelectric power)stations worldwide, 【24】______ tidal stations are still in the very early【25】______ of development.

As far as geographical【26】______ is concerned, HEP projects are to be found on lakes and rivers, while tidal【27】______ are constructed only at river mouths where tidal【28】______ is great. Unfortunately these are【29】______ in number. At present HEP stations are found mainly in Norway, Canada, Sweden and Brazil, whereas tidal plants are in【30】______ in France, Russia and China.

As regards capital【31】______ , both require very high investment. On the other hand, generating【32】______ are quite low in both cases. In fact, a large scale HEP plant is capable of producing power more【33】______ than conventional sources, such as coal, oil and nuclear plants. Tidal power also compares【34】______ with nuclear and oil generated electricity, 【35】______ the amount of money on production. 【36】______ HEP stations, tidal constructions have a long life【37】______ . It is estimated that they can operate for over 100 years. With respect to【38】______ of supply, tidal stations【39】______ from HEP ones in that they often can only supply power【40】______. HEP stations, however, pro vide a constant supply of electricity.

A．compatible

B．parallel

C．similar

D．identical

Humans live in a world where many other living things compete for food and places to breed. The pathogenic organisms, ,or pathogens, are often broadly called germs, which cause many diseases to be able to invade the human body and use its cells and flu- ids for their own needs. (46)

Pathogenic organisms can enter the body in various ways. Some —such as those that cause the common cold, pneumonia, and tuberculosis—are breathed in. (47) Still others—such as those that cause bacillary dysentery, cholera, and typhoid fever— get in the body through contaminated food, water, or utensils.

Insects can spread disease by acting as vectors, or carriers. . (48) Germs may also enter the body through the bite of a mosquito, louse, or other insect vector. Kinds of disease

Infectious, or communicable, diseases are those that can be passed between persons such as by means of airborne droplets from a cough or sneeze. Tiny organisms such as bacteria and fungi can produce infectious diseases. So can viruses. So can tiny worms. Whatever the causative agent might be, it survives in the person it infects and is passed on to another. Or, its eggs are passed on. . (49)

The asymptomatic carrier can then pass the disease on to someone else without even knowing he has it.

Noninfectious, or noncommunicable, diseases are caused by malfunctions of the body. These include organ or tissue degeneration, erratic cell growth, and faulty blood formation and flow. Also included are disturbances of the stomach and intestine, the endocrine system, and the urinary and reproductive systems. Some diseases can be caused by diet deficiencies, lapses in the body&39;s defense system, or a poorly operating nervous system.

. (50) These ailments include drug addiction, obesity, malnutrition, and pollution-caused health problems.

??A. A disease is a condition that impairs the proper function of the body.B. Ordinarily, the body&39;s defense system can ward off these invaders.C. Disability and illnesses can also be provoked by psychological and social factors.D. Sometimes, a disease-producing organism gets into a person who shows no symptoms of the disease.E. Others—such as those that cause venereal diseases—enter through sexual contact of human bodies.F. Flies can carry germs from human waste or other tainted materials to food and beverages.??
