Finding ways to 【B10】 this growing homeless population has become increasingly difficult. 【B11】 when homeless individuals manage to find a 【B12】 that will give them three meals a day and a place to sleep at night, a good number still spend the bulk of each day 【B13】 the street.

disappears and recuperation begins. The tired mind gathers new energy, and the memory improves.
Some adults require little sleep; others need eight to ten hours in every twenty-four hours. Infants sleep sixteen to eighteen hours daily, the amount gradually diminishing as they grow older. Young students may need twelve hours; university students may need ten. A worker with a physically demanding job may also need ten, whereas an executive working under pressure may manage on six to eight. Many famous people have little sleep. Napoleon Bonaparte, Thomas Edison and Charles Darwin apparently averaged only four to six hours a night.
Whatever your individual need, you can be sure that by the age of thirty you will have slept for a total more than twelve years. By the age you will also have developed a sleep routine: a favorite hour, a favorite position, and a rule you need to follow in order to rest comfortably.
Investigators have tried to find out how long a person can go without sleep. Several people have reached more than 115 hours nearly five days. Whatever the limit, it is absolute. Animals kept awake for from five to eight days have died of exhaustion. The limit for human beings is probably about a week.
(1).By writing this passage, the writer intends to tell us that _______.
A、sleep is important for good mental and physical health
B、a light sleep is as restful as a deep sleep
C、memory is improved during sleep
D、sleep is relatively unimportant for human beings
(2).The amount of the sleep required may ___.
A、tire an individual mind
B、help infants grow older
C、apply pressure on an executive
D、that they didn’t sleep long
(3).If a person is not allowed to follow his own sleep routine, he will probably _____.
A、never fall sleep
B、not sleep well
C、lost his memory
D、begin to daydream
(4).The author implies that if human beings are kept awake for more than a week the result _____.
A、is hard to imagine
B、will probably be a mental breakdown
C、is difficult to describe
D、will probably be dead
(5).From the amount of sleep Napoleon, Edison, Darwin required, we can conclude ___.
A、 that they were famous
B、 that they were executives
C、 hat they were intelligent
D、 that they didn’t sleep long

Apart from these sciences is philosophy, about which we will talk later. In the first place, all this is pure or theoretical knowledge, sought only for the purpose of understanding, in order to fulfill the need to understand that is intrinsic and con-substantial to man. What distinguishes man from animals is that he knows and needs to know. If man did not know that the world existed, and that the world was of a certain kind, that he was in the world and that he himself was of a certain kind, he wouldn't be man. The technical aspects or applications of knowledge are equally necessary for man and are of the greatest importance, because they also contribute to defining him as man and permit him to pursue a life increasingly more truly human.
But even while enjoying the results of technical progress, man must defend the primacy and autonomy of pure knowledge. Knowledge sought directly for its practical applications will have immediate and foreseeable success, but not the kind of important result whose revolutionary scope is for the most part unforeseen, except by the imagination of the Utopians. Let me recall a well-known example. If the Greek mathematicians had not applied themselves to the investigation of conic section zealously and without the least suspicion that it might someday be useful, it would not have been possible centuries later to navigate far from shore. The first men to study the nature of electricity could not imagine that their experiments, carried on because of mere intellectual curiosity, 'would eventually lead to modern electrical technology, without which we can scarcely conceive of contemporary life.
Pure knowledge is valuable for its own sake, because the human spirit cannot resign itself to ignorance. But, in addition, it is the foundation for practical results that would not have been reached if this knowledge had not been sought disinterestedly.
The author does not include among the sciences the study of
A.literature.
B.chemistry.
C.astronomy.
D.anthropology.

This factor is exercise. In the cities, it is often faster and less frustrating to walk short distances than to wait for a bus. Even taking public transportation often requires some walking. Smaller apartment houses have no elevators, and so tenants must climb stairs. City dwellers(居民) can usually walk to local supermarkets. Since parking spaces are hard to find, there is often no alternative to walking.
On the other hand, those who live in the country and suburbs do not have to walk every day. In fact the opposite is often true. To go to school, work or almost anywhere else, they must ride in cars.
1)、The Vienna survey may help to explain the long life of people like Mrs. Groger.

The trend in sports, though, may be obscuring an unrecognized reality: Americans have generally stopped growing. Though typically about two inches taller now than 140 years ago, today''s people- especially those born to families who have lived in the U.S. for many generations- apparently reached their limit in the early 1960s. And they aren’t likely to get any taller. In the general population today, at this genetic, environmental level, we''ve pretty much gone as far as we can go, says anthropologist William Cameron Chumlea of Wright State University. In the case of NBA players, their increase in height appears to result from the increasingly common practice of recruiting players from all over the world.
Growth, which rarely continues beyond the age of 20, demands calories and nutrients–notably, protein–to feed expanding tissues. At the start of the 20th century, under-nutrition and childhood infections got in the way. But as diet and health improved, children and adolescents have, on average, increased in height by about an inch and a half every 20 years, a pattern known as the secular trend in height. Yet according to the Centers for Disease Control and Prevention, average height- 5′9〞for men, 5′4〞for women- hasn''t really changed since 1960.
Genetically speaking, there are advantages to avoiding substantial height. During childbirth, larger babies have more difficulty passing through the birth canal. Moreover, even though humans have been upright for millions of years, our feet and back continue to struggle with bipedal posture and cannot easily withstand repeated strain imposed by oversize limbs. There are some real constraints that are set by the genetic architecture of the individual organism, says anthropologist William Leonard of Northwestern University.
Genetic maximums can change, but don''t expect this to happen soon. Claire C. Gordon, senior anthropologist at the Army Research Center in Natick, Mass, ensures that 90 percent of the uniforms and workstations fit recruits without alteration. She says that, unlike those for basketball, the length of military uniforms has not changed for some time. And if you need to predict human height in the near future to design a piece of equipment, Gordon says that by and large, you could use today’s data and feel fairly confident.

A.illustrate the change of height of NBA players.
B.show the popularity of NBA players in the U.S……
C.compare different generations of NBA players.
