After the new system has settled down people in non-computer jobs are not always replaced when they leave,resulting in a decrease in the number of employees． This decrease is sometimes balanced by a substantial increase in the activity of the firm, resulting from the introduction of computers． The attitudes of workers towards computers vary． There is fear of widespread unemployment and of the takeover of many jobs by computer-trained workers, making promotion for older workers not skilled in computers more difficult． On the other hand,many workers regard the trend toward wider use of computers inevitabl

Salt is as necessary to life as water. In many areas of Africa people once drank the urine (尿) of animals because they had no other source of salt. Without salt, human beings die.
The human body demands that the amount of salt in the blood always stay the same.When the body does not get enough salt, it protects itself by letting less salt leave the body in urine and sweat. But it cannot reduce this output to zero. Some salt is always escaping. On a completely saltless diet, like that of some people in Africa, the body steadily loses small amounts of salt through the kidneys (肾) and sweat glands (腺). It then tries to ad-just to this loss by speeding up its secretion (分泌) of water. In this way, the body attempts to keep the amount of salt in the blood at the necessary level. The result is a slow drying up of body and, finally, death. The person dies of thirst.
In cases where there is little or no water to drink, the body tries to do the opposite thing. Again, it must keep the salt level in the blood constant. Because it has little water, it attempts to stop water from leaving the body and to increase its secretion of salt. But, as with the escaping salt, it cannot be completely successful. Some water still leaves and the person eventually dies of thirst. In short, the body's normal needs for salt and for water are both parts of the same important need to keep the salt level in the blood constant.
Some African people once drank animal urine______.
A．when they were going to die
B．because they were thirsty
C．because there was little salt
D．because they were short of water

There are different ways in which people try to deal with the problem of energy. One way is the greater production of common energy sources, such as coal, oil and gas. The trouble with these sources, however, is that they are not renewable.
Another way is energy conservation (节能 ), which means using energy more efficiently (有效地 ). In some very cold countries people build special houses to save energy. They place materials between the inside and the outside of the walls of the house to keep the cold out and the warmth in. The house is heated by the lights, the body heat of the people and the other equipment in it.
Finally, renewable energy sources are used even though they are often expensive to develop. One form. of these is geothermal energy. In certain parts of the world the temperature of the earth increases thirty degrees centigrade with each kilometer down. At six kilometers, therefore, it rises to nearly two hundred degrees. To get the heat, water is pumped (压;抽 ) down into the rocks and back up to the surface. Heat from the earth is already used in certain countries.
1、How many ways of dealing with the energy problem are discussed in the text？ ()
A、Two.
B、Three.
C、Four.
D、Five.
2、From the text we learn that coal().
A、is quite easy to produce
B、is not used most efficiently

A、show the excellent skills of the builders
B、serve as an example of energy conservation
C、are heated by different sources of energy
D、are warmer than other types of houses
4、The underlined words "geothermal energy" in the third paragraph mean ().
A、renewable source
B、 underground source
C、 heat inside the earth
D、 temperature of the earth
5、At a place where the surface temperature is 15°C, how deep do you have to dig so as to get a temperature of 75 °C ？ ()
A、One km.
