单选题{{B}}Passage Two{{/B}} In a perfectly free and open market economy, the type of employer—government or private—should have little or no impact on the earnings differentials between women and men. However, if there is discrimination against one sex, it is unlikely that the degree of discrimination by government and private employers will be the same. Differences in the degree of discrimination would result in earnings differentials associated with the type of employer. Given the nature of government and private employers, it seems most likely that discrimination by private employers would be greater. Thus, one would expect that, if women are being discriminated against, government employment would have a positive effect on women's earnings as compared with their earnings from private employment. The results of a study by Fuchs support this assumption. Fuchs' results suggest that the earnings of women in an industry composed entirely of government employees would be 14.6 percent greater than the earnings of women in an industry composed exclusively of private employees, other things being equal. In addition, both Fuchs and Sanborn have suggested that the effect of discrimination by consumers on the earnings of self-employed women may be greater than the effect of either government or private employer discrimination on the earnings of women employees. To test this hypothesis, Brown selected a large sample of white male and female workers from the 1970 census and divided them into three categories: private employees, government employees, and self-employed. (Black workers were excluded from the sample to avoid picking up earnings differentials that were the result of racial disparities.) Brown's research design controlled for education, labor-force participation, mobility, motivation, and age in order to eliminate these factors as explanations of the study's results. Brown's results suggest that men and women are not treated the came by employers and consumers. For men, self-employment is the highest earnings category, with private employment next, and government lowest. For women, this order is reversed. One can infer from Brown's results that consumers discriminate against self-employed women. In addition, self-employed women may have more difficulty than men in getting good employees and may encounter discrimination from suppliers and from financial institutions. Brown's results are clearly consistent with Fuchs' argument that discrimination by consumers has a greater impact on the earnings of women than does discrimination by either government or private employers. Also, the fact the women do better working for government than for private employers implies that private employers are discriminating against women. The results do not prove that government does not discriminate against women. They do, however, demonstrate that if government is discriminating against women, its discriminating is not having as much effect on women's earnings as is discrimination in the private sector.

单选题Archimedes was a famous Greek mathematician and scientist. He was born around 287 BC and he died in the year 212 BC. Archimedes is most well-known for one specific idea that he came up with. "Archimedes's Principle" states that a solid object which is immersed in a liquid is pushed up by a force which is equal to the weight of the water that the object moves. For example, if you put a piece of wood and a piece of gold the same size in water, only the wood will float. Both the wood and gold move the same amount of water, but the wood weighs less than this water, while the gold weighs more. It is believed that Archimedes discovered this principle when the king of Syracuse asked him to solve a problem. The king wanted to know if his crown was pure gold or a mixture of gold and silver. The king, of course, did not melt his crown to find out. The idea came to Archimedes as he lowered himself into his bath. He noticed how the water spilled out of the tub. He decided to use the same idea for the crown. He knew that a gold crown immersed in water would weigh more than one made of silver. The experiment was done and the goldsmith was proved guilty of trying to cheat the king.

单选题In recent months, RAND researchers have teamed up with a dozen Los Angeles lunch trucks to test healthier menu items—chicken breasts and grilled fish alongside the usual tacos and hamburgers. The results have been modest but promising. The healthy meals were never best-sellers, but they did well enough that a majority of the truck owners plan to keep them on the menu. That"s important, because the trucks tend to serve working-class Latino communities, where obesity rates are high and healthy food can be scarce, leading researcher Deborah Cohen said. "It"s important that the providers are offering these meals," she said. "I think what we showed is that it"s completely feasible." Cohen has spent years arguing that restaurants, grocery stores and other food outlets should take more responsibility for the nation"s obesity epidemic, and more action to stop it. More than one-third of U. S. adults are obese, according to federal statistics, adding billions of dollars to the nation"s health care costs each year. A lunch truck may seem like an unlikely testing ground for healthy menu items, the four-wheel equivalent of a fast-food joint. But most are morn-and-pop operations where cooks make food by hand, using fresh ingredients and often for underserved communities. Cohen called them a "good lab." These aren"t the trendy food trucks that have started to sell fusion tacos and reimagined grilled cheese to hip, young urbanites. These have been part of blue-collar Los Angeles for generations, where they"re known as loncheras, after the Spanglish word lonche, for lunch. Working with a $ 275,000 grant from the National Institutes of Health, RAND researchers enlisted nearly 20 loncheras for a six-month trial they named "La Comida Perfecta," or "The Perfect Meal" About a third of the truck owners later dropped out, leaving 12 who worked with a nutritionist, created their own healthy meals, and then put them on the menu. The six-month pilot program didn"t yield big sales numbers at most trucks, but it did yield some valuable insight into the challenges, big and small, of changing food habits, the researchers said. Truck operators had trouble swapping out their corn tortillas for whole wheat, for example, and their Latino customers especially didn"t care for the brown rice that replaced their traditional Mexican rice. Nearly half of the truck customers were regulars, surveys found, and most knew what they wanted without even looking at the menu. In poorer neighborhoods and blue-collar work sites, that was usually a couple of $1 tacos, not a $7 plate with fruit and salad.

单选题We were late as usual. My husband had 1 watering the flowers in the garden by himself, and when he discovered that he couldn"t manage, he asked me for 2 at the last moment. So now we had only one hour to get to the airport. Luckily, there were not many cars 3 buses on the road and we were 4 to get there just in time. We checked in and went straight to a big hall to wait for our flight to be called. We waited and waited 5 no announcement was made. We asked for 6 and the girl there told us the plane hadn"t even arrived yet. In the end, there came an announcement telling us that those 7 for flight No. 108 could get a free meal voucher and that the plane hadn"t left Spain 8 technical problems. We thought that meant 9 it wasn"t safe for the plane to 10 . We waited again for a long time until late evening when we were asked to report again. This time we were 11 free vouchers to spend the night in a nearby hotel. The next morning after a 12 night because of all the planes taking off and landing, we were reported back to the airport. Guess 13 had happened while we were asleep. Our plane had arrived and taken off again. All the other 14 had been waken up in the night to catch the plane, but for some reasons or other we had been 15 . You can imagine how we felt!

单选题Avoid the rush-hour' must be the slogan of large cities the world over. If it is, it's a slogan no one takes the least notice of. Twice a day, with predictable regularity, the pot boils over. Wherever you look it's people, people, people. The trains which leave or arrive every few minutes are packed: an endless procession of human sardine tins. The streets are so crowded, there is hardly room to move on the pavements. The queues for buses reach staggering proportions. It takes ages for a bus to get to you because the traffic on the roads has virtually come to a standstill. Even when a bus does at last arrive, it's so full, it can't take any more passengers. This whole crazy system of commuting stretches man's resources to the utmost. The smallest unforeseen event can bring about conditions of utter chaos. A power-cut, for instance, an exceptionally heavy snowfall or a minor derailment must always make city-dwellers realise how precarious the balance is. The extraordinary thing is not that people put up with these conditions, but that they actually chose them in preference to anything else. Large modern cities are too big to control. They impose their own living condition on the people who inhabit them. City-dwellers are obliged by their environment to adopt a wholly unnatural way of life. They lose touch with the land and rhythm of nature. It is possible to live such an air-conditioned existence in a large city that you are barely conscious of the seasons. A few flowers in a public park (if you have the time to visit it) may remind you that it is spring or summer. A few leaves clinging to the pavement may remind you that it is autumn. Beyond that, what is going on in nature seems totally irrelevant. All the simple, good things of life like sunshine and fresh air are at a premium. Tall buildings block out the sun. Traffic fumes pollute the atmosphere. Even the distinction between day and night is lost. The flow of traffic goes on unceasingly and the noise never stops. The funny thin about it all is that you pay dearly for the 'privilege' of living in a city. The demand for accommodation is so great that it is often impossible for ordinary people to buy a house of their own. Exorbitant rents must be paid for tiny flats which even country hens would disdain to live in. Accommodation apart, the cost of living is very high. Just about everything you buy is likely to be more expensive than it would be in the country. In addition to all this, city-dwellers live under constant threat. The crime rate in most cities is very high. House are burgled with alarming frequency. Cities breed crime and violence and are full of places you would be afraid to visit at night. If you think about it, they're not really fit to live in at all. Can anyone really doubt that the country is what man was born for and where he truly belongs?

单选题Nuclear power's danger to health, safety, and even life itself can be summed up in one word: radiation. Nuclear radiation has a certain mystery about it, partly because it cannot be detected by human senses. It can't be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around us but we can't detect them, sense them, without a radio receiver. Similarly, we can't sense radio activity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things. At very high levels, radiation can kill an animal or human being outright by killing masses of cells in vital organs. But even the lowest levels can do serious damage. There is no level of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be significant. This is the case when only a few cells are hit. And if they are killed outright, your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They reproduce themselves in a deformed way. They can grow into cancer. Sometimes this does not show up for many years. This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the victim being aware at the time that damage has occurred. A person can he irradiated and feel fine, then die of cancer five, ten, or twenty years later as a result. Or a child can be born weak or liable to serious illness as a result of radiation absorbed by its grandparents. Radiation can hurt us. We must know the truth.

单选题An orator, whose purpose is to persuade men, must speak the things they wish to hear, an orator, whose purpose is to move men, must also avoid disturbing the emotional effect by any obtrusion of intellectual antagonism, but an author, whose purpose is to instruct men, who appeals to the intellect, must be careless of their opinions and think only of truth. It will often be a question when a man is or is not wise in advancing an unpalatable opinion, or in preaching heresies. But it can never be a question that a man should be silent if unprepared to speak the truth as he conceives it. Deference to popular opinion is one great source of bad writing and is all the more disastrous because the deference is paid to some purely hypothetical requirement. When a man fails to see the truth of certain generally accepted views, there is no law compelling him to provoke animosity by announcing his dissent. He may be excused if he shrink from the lurid glory of martyrdom. He may be justified in not placing himself in a position of singularity. He may even be commended for not helping to perplex mankind with doubts which he feels to be founded on limited and possibly erroneous investigation. But if allegiance to truth lays no stern command upon him to speak out his immature dissent, it does lay a stern command not to speak out hypocritical assent. There are many justifications of silence, there can be none of insincerity.
