It was 3:12 a.m. when nine-year-old Glenn Kreamer awoke to the smell of burning. Except for the crackling of flames somewhere below there was not a sound in the two-storey house at Baldwin, Long Island.
With his father away on night duty at a local factory, Glenn was worried about the safety of his mother, his sister Karen, 14 and his 12-year-old brother Todd. He ran downstairs through the smoke filled house to push and pull at Karen and Todd until they sat up. Then he helped each one through the house to the safety of the garden. There, his sister and brother, taking short and quick breaths and coughing, collapsed on the lawn.
The nine-year-old raced back into the house and upstairs to his mother's room. He found it impossible to wake her up. Mrs. Kreamer, a victim of the smoke, was unconscious, and there was nobody to help Glenn carry her to the garden. But the boy remained calm and, as a fireman said later, "acted with all the self-control of a trained adult."
On the bedroom telephone, luckily still wording, Glenn called his father and, leaving Mr. Kreamer to telephone the fire brigade and ambulance service, got on with the task of saving his mother.
First he filled a bucket with water from the bathroom and threw water over his mother and her bed. Then, with a wet cloth around his head he went back to the garden.
He could hear the fire engine coming up, but how would the firemen find his mother in the smoke-filled house where flames had almost swallowed up the ground floor？
Grasping firmly a ball of string from the garage, Glenn raced back into the house and dashed upstairs to his mother's room. Tying one end of the string to her hand he ran back, laying out the string as he went, through the hall and back out into the garden.
Minutes later he was telling fire chief John Coughlan: "The string will lead you to mother." Mrs. Kreamer was carried to safety as the flames were breaking through her bedroom floor.
Why did Glenn run downstairs first？
A．He wanted to find out what was happening.
B．He was worded about his mother's safety.
C．He wanted to save his sister and brother.
D．He went to see if his father had come back from work.

In the US, poll after poll has shown a majority in favour of animal experimentation, even without statements about its value. Why is opinion in Britain so different？ I think that there are two reasons.
The first is the success of antivivisection campaigners in lampooning animal research as outdated, intentionally cruel, "bad" science, which achieves nothing. All drugs and procedures developed with the help of animal tests are said to be dangerous. The occasional failure of animal testing to identify a dangerous drug is developed as an argument for abandoning safety tests involving animals altogether--with no mention of the terrible human suffering that this would cause. They say that "alternative" methods already exist for all animal experiments, but the fact is that the law specifically forbids animal use if there is any alternative.
The second reason is that scientists and doctors have failed to oppose such misrepresentation. In the early 1990s, animal rights campaigning in the US was met with much more forthright defense, not only by the major scientific societies, funding agencies and medical organizations, but also by the US government.
To be positive, there are many encouraging features of the New Scientist poll. Interestingly, the public seems to employ the same kind of utilitarian philosophy that underpins the law in Britain--weighing potential benefits against the species involved (thus, monkeys are more "valuable" than mice) and the likelihood of suffering.
Clearly, people in Britain do not recognize the essential link between animal research and testing and the medical treatments that they receive. Only 18 percent of those who had taken (or had a close family member who had taken a drug prescribed for a serious illness realized that the drug had been tested on animals, as all drugs are. Obviously, a large majority of those surveyed believe that they can happily benefit from medical treatment without taking advantage of animal research. No wonder so many people oppose it when asked the straight yes/no question.
The views of the public must be respected. But this poll tells us that, while they are open to persuasion, their reaction is based on misunderstanding. The responsibility for providing honest evidence for the public lies not just with those who use animals in their research, but with other scientists who depend on that work. It lies with the doctors who benefit from animal research, with the pharmaceuticals and biotech industries, and the medical charities and funding age, les whose work would be crippled without it. But most of all, responsibility rests with government, which should cultivate serious and transparent debate between those of different opinion, and provide the public--especially young people--with the honest evidence they need and deserve.
In the first sentence of Paragraph 3, "such misrepresentation" refers to ______.
A．the idea that other methods can be substituted for animal research
B．the claim that animal experiment is intentionally cruel
C．the belief that all drugs developed with animal tests are dangerous
D．the fact that scientists and medical organizations support animal experimentation

There are two sorts of people in the world, who with equal degrees of health, and wealth, and the other comforts of life, become, the one happy, and tile other miserable. This arises very much from the different views in which they consider things, persons, and events.
In whatever situation men can be placed, they may find conveniences and inconveniencies; in whatever company, they may find persons and conversation more or less pleasing; at whatever table, they may meet with meats or drinks of better and worse taste, dishes better or worse dressed; in whatever climate they will find good and bad weather; under whatever government, they may find good and bad laws, and good and bad administration of those laws; in every poem or work of genius they may see faults and beauties; in almost every face and every person, they may discover fine features and effects, good and bad qualities.
Under these circumstances, the two kinds of people above mentioned fix their attention, those who are to be happy, on the conveniences of things, the pleasant parts of conversation, the well-dressed dishes, the goodness of the wines, the fine weather, and enjoy all with cheerfulness. Those who are to be unhappy, think and speak only of the contraries. Hence they are continually discontented themselves, and by their remarks sour the pleasures of society, offend personally many people, and make themselves everywhere disagreeable. If this turn of mind were founded in nature, such unhappy persons would be the more to be pitied. The tendency to criticize and to be disgusted is perhaps taken up originally by imitation, and is unawares grown into a habit, which at present strong may nevertheless be cured when those who have it are convinced of its bad effects on their felicity.
I hope this little admonition may be of service to them, and put them on changing a habit, which in the exercise is chiefly an act of imagination yet has serious consequences in life, as it brings on real grieves and misfortunes. For many are offended, nobody loves this sort of people, no one shows them more than the most common civility and respect, and scarcely that; and this frequently puts them out of humor, and draws them into disputes and contentions. If they aim at obtaining some advantage in rank or fortune, nobody wishes them success, or will stir a step, or speak a word, to favor their pretensions. If they incur public censure or disgrace, no one will defend or excuse, and many join to aggravate their misconduct, and render them completely odious. If these people will not change this bad habit, and condescend to be pleased with what is pleasing, without fretting themselves and others about the contraries, it is good for others to avoid an acquaintance with them, which is always disagreeable, and sometimes very inconvenient, especially when one finds one's self entangled in their quarrels.
An old philosophical friend of mine grown from experience, was very cautious in this particular, and carefully avoided any intimacy with such people. He had, like other philosophers, a thermometer to show him the heat of the weather, and a barometer to mark when it was likely to prove good or bad; but, there being no instrument invented to discover, at first sight, this unpleasing disposition in a person. He for that purpose made use of his legs, one of which was remarkably handsome, the other, by some accident, crooked and deformed. If a stranger, at the first interview, regarded his ugly leg more than his handsome one, he doubted him. If he spoke of it, took no notice of the handsome leg, that was sufficient to determine my philosopher to have no further acquaintance with him. Every body has not this two-legged instrument, but every one with a little attention, may observe signs of that carping, faultfinding disposition, and take the same resolution of avoiding the acquaintance of those infected with it. I therefore advise those critical, querulous, dis
A．their comforts of life
B．their minds
C．their feelings

There are two great mysteries about the beach. One is why human beings flock there by thousands, only to prostrate(俯卧) themselves in dense packs of glistening flesh. The other is why the sand goes there. Strange as it seems, oceanographers have never really understood why sand piles up on the shore. Now Douglas Inman and Daniel Conley think they have solved the puzzle.
The puzzle had to do with waves. Though it might seem intuitive that waves carry water to shore, and sand along with it, it's not that simple. The crest(浪尖)of a passing wave lifts a given hit of water upward and landward, but the ensuing trough(波谷) pushes the water back down and Out to sea. Near the bottom, there the sand is, the water was always assumed to just slide back and forth—and the sand with it. "If you take a very aloof look at a beach," says Inman, "you'll realize that if the two motions move sand back and forth the same amount, then all the sand should end up in deep water.'
So for beaches to exist, the crest's onshore flow must somehow move enough sand up the beach to counter the seaward tug of both the trough and gravity . The pressure changes in the sand bed, Inman and Conley think, are the key to beach creation. They found that sand doesn't just slide back and forth with each passing wave. Under a trough, it does slide seaward, in a thin layer just above the bottom. But under a crest its movement is often more elaborate. The higher pressure under a crest—higher because the water is piled higher—forces water into the porous(多孔的) sand. This creates strong whirlpools just above the sand, which help loosen it. As the crest passes overhead, the sand first rushes across the bottom; then it abruptly turns violent lifting off the bottom in large, boiling bunches. Finally, just after the crest passes, the sand explodes up into the great water column. The boiling and rushing move more sand than the backsliding under a trough, so there's a net movement of sand toward the shore.
What is the primary purpose of this passage？
A．To explain why sand piles up on the beaches.
B．To explain why men only prostrate in the sea.
C．To propose a new explanation of a phenomenon.
D．To refute a misconception.
