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

Many objects in daily use have clearly been influenced by science, but their form. and function, their dimensions and appearances were determined by technologists, artisans, designers, inventors, and engineers-using nonscientific modes of thought. Many features and qualities of the objects that a technologist thinks about can't be reduced to unambiguous verbal descriptions; they are dealt with in the mind by a visual, nonverbal process. In the development of Western technology, it has been nonverbal thinking, by and large, that has fixed the outlines and filled in the details, and rockets exist not because of geometry or thermodynamics, but because they were first a picture in the minds of those who built them.
The creative shaping process of a technologist's mind can be seen in nearly every artifact that exists. For example, in designing a diesel engine, a technologist might impress individual ways of non-verbal thinking on the machine by continually using an intuitive sense of tightness and fitness. What would be the shape of the combustion chamber？ Where should be the valves played？ Should it have a long or short piston？ Such questions have a range of answers that are supplied by experience, by physical requirements, by limitations of available space, and not least by a sense of form. Some decisions, such as wall thickness and pin diameter, may depend on scientific calculations, but the nonscientific component of design remains primary.
Design courses, then, should be an essential element in engineering curricula, nonverbal thinking, a central mechanism in engineering design, involves perceptions, the stock-in-trade of the artist, not the scientist. Because perceptive processes are not assumed, to entail "hard thinking", nonverbal thought is sometimes seen as a primitive stage in the development of cognitive processes and inferior to verbal or mathematical thought. But it is paradoxical that when the staff of the Historic American Engineering Record wished to have drawings made of machines and isometric views of industrial processes for its historical record of American engineering, the only college students with the requisite abilities were not engineering students, but rather students attending architectural schools;
If courses in design, which in a strongly analytical engineering curriculum provide the background required for practical problem-solving, are not provided, we can expect to encounter silly but costly errors occurring in advanced engineering systems. For example, early models of high-speed railroad cars loaded with sophisticated controls were unable to operate in a snowstorm because a fan sucked snow into the electrical system. Absurd random failures that plague automatic control systems are not merely trivial aberrations; they are a reflection of the chaos that results when design is assumed to be primarily a problem in mathematics.
In the passage, the author is primarily concerned with______.
A．identifying the kinds of thinking that are used by technologists
B．stressing the importance of nonverbal thinking in engineering design
C．proposing a new role for nonscientific thinking in the development of technology
D．criticizing engineering schools for emphasizing science in engineering curricula

Of the many problems in the world today, none is as widespread, or as old, as crime. Crime has many forms, including crimes against property, person, and government. Crime, in all its forms, penetrates every layer of society and touches every human being. You may never have been robbed, but you suffer the increased cost of store- bought items because of others’shoplifting.
Your house is not worth as much today as it was a few years ago because of the increased crime rate in your neighborhood. Perhaps your business is not doing as well as it used to because tourism is down due to increased terrorism in your part of the world.
Crime, especially violent crime, has risen to a point where many people are afraid to walk al one in their own neighborhoods, afraid to open their door after dark, afraid to speak out and voice their own opinions. Some citizens have reacted by arming themselves with various weapons, legal and illegal, to defend themselves. Citizen groups have taken the law into their own hands by forming their own vigilante groups to administer judgment when they feel that their criminal justice system has not performed its duty.
Experts argue whether the number of crimes committed is actually on the rise or whether there is simply a rise in the number of crimes reported. This issue is particularly true in cases of marriage violence, the abuse of spouse or children. Throughout much of history, cases of family violence and neglect often went unreported because of the attitude of society, which considered family matters to be private.
Other experts argue about who is really to blame for criminal behavior. the individual or society. Researchers in the United States and Canada have identified several factors in society that contribute to the crime rate: massive urbanization, unemployment and poverty, and a large immigrant population. Other countries are more affected by factors such as politics, government corruption, and religion.
(1)What does the passage mainly discuss？
A、Crime the widespread problem.
B、The results caused by increasing violent crime.
C、Factors contributing to the crime rate.
D、Citizen groups combating crimes.
(2)The word shoplifting in line 4 is closest in meaning to _____________.
A、the crime of lifting the ban
B、the crime of moving the shops away
C、the crime of robbing things from shops
D、the crime of stealing things from shops
(3)Why does the author in Paragraph 2 mention citizen groups forming their own vigilante groups？
A、To show the criminal justice system is not just
B、To show citizens are powerful in combating crimes
C、To show crime is a serious social problem
D、To show citizens have rights in combating crimes
(4)According to the passage, which of the following are the factors contributing to United States’criminal behavior？
A、Politics, unemployment, poverty and a large immigrant population.
B、Massive urbanization, unemployment and poverty, and a large immigrant population.
C、Politics, government corruption, poverty and religion.
D、Massive urbanization, unemployment and poverty, and government corruption.

A、Since you have never been robbed, you are not a victim of crime.
B、Some people use illegal weapons to defend themselves.
C、Only the individual should be responsible for the criminal behavior.
D、Family violence and neglect are considered family matters, and therefore private, so they are not crimes.
