单选题 The effect of the baby boom on the schools helped to make possible a shift in thinking about the role of public education in the 1950's. In the 1920's but especially {{U}}(21) {{/U}} the Depression of the 1930's, the United States experienced a {{U}}(22) {{/U}} birth rate. Then with the prosperity {{U}}(23) {{/U}}.on by the Second World War and the economic boom that followed it, young people married and {{U}}(24) {{/U}} households earlier and began to {{U}}(25) {{/U}} larger families than had their {{U}}(26) {{/U}} during the Depression. Birth rates rose to 102 per thousand in 1946, 106. 2 in 1950, and 118 in 1955 {{U}}(27) {{/U}} economics was probably the most important {{U}}(28) {{/U}}. it is not the only explanation for the baby boom. The increased value placed {{U}}(29) {{/U}} the idea of the family also helps to {{U}}(30) {{/U}} this rise in birth rates. The baby boomers began streaming {{U}}(31) {{/U}} the first grade by the mid-1940's and became a {{U}}(32) {{/U}} by 1950. The public school system suddenly found itself {{U}}(33) {{/U}}. The wartime economy-meant that few new schools were built between 1940 and 1945. {{U}}(34) {{/U}} large numbers of teachers left their profession during that period for better-paying jobs elsewhere. {{U}}(35) {{/U}}, in the 1950's and 1960's, the baby boom hit an antiquated and inadequate school system. Consequently, the custodial rhetoric of the 1930's no longer made {{U}}(36) {{/U}}: keeping youths ages sixteen and older out of the labor market by keeping them in school could no longer be a high {{U}}(37) {{/U}} for an institution unable to find space and staff to teach younger children. With the baby boom, the focus of educators {{U}}(38) {{/U}} turned toward the lower grades and back to basic academic skills and {{U}}(39) {{/U}}. The system no longer had much {{U}}(40) {{/U}} in offering nontraditional, new, and extra services to older youths.

Mark your answers on ANSWTR SHEET 1.{{/I}} A significant portion of industry and transportation burns fossil fuels, such as gasoline. When these fuels burn, chemicals and particulate matter are released into the atmosphere. Although a vast number of substances contribute to air pollution, the most common air pollutants contain carbon, sulfur, and nitrogen. 41 __________. Acid rain forms when sulfur dioxide and nitrous oxide transform into sulfuric acid and nitric acid in the atmosphere and come back to Earth in precipitation. Acid rain has made numerous lakes so acidic that they no longer support fish populations. 42 __________. Estimates suggest that nearly 1.5 billion people worldwide lack safe drinking water and that at least 5 million deaths per year can be attributed to waterborne diseases. Water pollution may come from point sources or nonpoint sources. Point sources discharge pollutants from specific locations, such as factories, sewage treatment plants, and oil tankers. The technology exists to monitor and regulate point sources of pollution, although in some areas this occurs only sporadically. Pollution from nonpoint sources occurs when rainfall or snowmelt moves over and through the ground. 43 __________. With almost 80 percent of the planet covered by oceans, people have long acted as if those bodies of water could serve as a limitless dumping ground for wastes. However, raw sewage, garbage, and oil spills have begun to overwhelm the diluting capabilities of tile oceans, and most coastal waters are now polluted, threatening marine wildlife. 44 __________. Water that collects beneath the ground is called groundwater. Worldwide, groundwater is 40 times more abundant than fresh water in streams and lakes. In the United States, approximately half the drinking water comes from groundwater. Although groundwater is a renewable resource, reserves replenish relatively slowly. Presently, groundwater in the United States is withdrawn approximately 4 times faster than it is naturally replaced. 45 __________. A. Beaches around the world close regularly, often because the surrounding waters contain high levels of bacteria from sewage disposal. B. These chemicals interact with one another and with ultraviolet radiation in sunlight in dangerous ways. Smog, usually found in urban areas with large numbers of automobiles, forms when nitrogen oxides react with hydrocarbons in the air to produce aldehydes and ketones. Smog can cause serious health problems. C. Acid rain is also responsible for the decline of many forest ecosystems worldwide, including Germany's Black Forest and forests throughout the eastern United States. D. In addition to groundwater depletion, scientists worry about groundwater contamination, which arises from leaking underground storage tanks, poorly designed industrial waste ponds, and seepage from the deep-well injection of hazardous wastes into underground geologic formations. E. The Ogallala Aquifer, a huge underground reservoir stretching under eight states of the Great Plains, is drawn down at rates exceeding 100 times the replacement rate. Agricultural practices depending on this source of water need to change within a generation in order to save this groundwater source. F. As the runoff moves, it picks up and carries away pollutants, such as pesticides and fertilizers, depositing the pollutants into lakes, rivers, wetlands, coastal waters, and even underground sources of drinking water. Pollution arising from nonpoint sources accounts for a majority of the contaminants in streams and lakes. G. By some estimates, on average, 25 percent of usable groundwater is contaminated, and in some areas as much as 75 percent is contaminated.

单选题The guy in the next cubicle is yammering away on the phone. Across the room, someone begins cursing loudly at a jammed copy machine. The headphones on the other end of your desk suddenly look very appealing. Would anyone mind if you tapped into your iTunes playlist for a while? Some workers like to listen to music when they find themselves losing focus. They may also plug in their earbuds to escape an environment that"s too noisy—or too quiet—or to make a repetitive job feel more lively. In biological terms, melodious sounds help encourage the release of dopamine (a chemical found in brain) in the reward area of the brain, as would eating a delicacy, looking at something appealing or smelling a pleasant aroma, said Dr. Amit Seed, a physician of integrative medicine with the Mayo Clinic. People"s minds tend to wander, "and we know that a wandering mind is unhappy," Dr. Seed said. "Most of that time, we are focusing on the imperfections of life." Music can bring us back to the present moment. "It breaks you out of just thinking one way," said Teresa Lesiuk, an assistant professor in the music therapy program at the University of Miami. Dr. Lesiuk"s research focuses on how music affects workplace performance. In one study involving information technology specialists, she found that those who listened to music completed their tasks more quickly and came up with better ideas than those who didn"t, because the music improved their mood. Dr. Lesiuk found that personal choice in music was very important. She allowed participants in her study to select whatever music they liked and to listen as long as they wanted. Those who were moderately skilled at their jobs benefited the most, while experts saw little or no effect. And some novices regarded the music as distracting. Dr. Lesiuk has also found that the older people are, the less time they spend listening to music at work. Few companies have policies about music listening, said Paul Flaharty, a regional vice president at a staffing agency. But it is still a good idea to check with your manager, even if you see others wearing headphones in the office. For those who choose to listen to music, it"s best to set limits, because wearing headphones for an entire shift can be perceived as rude by those nearby.

单选题 Some time between digesting Christmas dinner and putting your head back down to work, spare a thought or two for the cranberry. It is, of course, a{{U}} (1) {{/U}}of Christmas: merry bright red, bittersweetly delicious with turkey and the very devil to get out of the tablecloth{{U}} (2) {{/U}}spilled.

Ocean Spray's "flavoured fruit pieces" (FFPS, to the trade) taste like orange, cherry, raspberry or any {{U}}(6) {{/U}}of other fruits. They are in fact cranberries. Why make a cranberry taste like an orange? Mostly because it is a{{U}} (7) {{/U}}little fruit: FFPS have a shelf-life of two years.

单选题The one accident situation where immediate action must be taken is when a person stops breathing. This might be the result of drowning, electrocution, suffocation, head injury caused by a fall, poisoning or a variety of other accidents. If someone has stopped breathing, however, there may be a simpler cause; the breathing passages may be blocked by food, vomit, saliva or even the tongue. Whatever the cause, it is imperative that breathing is restarted quickly, as otherwise brain damage may result. Act quickly: lay the casualty flat on his back, and pull back the head while holding the jaws clenched. This prevents the tongue from falling back into the throat and blocking the air passages. If any foreign matter like sand or vomit can be seen in the victim" s mouth or throat, scoop it out with the fingers. False teeth are a particular hazard and often fall back into the throat of an unconscious person. If breathing does not start immediately, you must begin artificial respiration right away, by breathing directly into the casualty" s lungs through the mouth or nose. . . As you exhale deeply through the casualty" s nose, it is necessary to hold their mouth firmly closed. If you are breathing into the mouth, however, pinch the nostrils to stop the escape of air. If the airways are not obstructed you will see the chest of the casualty" s lungs. Each time you blow, turn your head to check that there is this regular rise and fall of the chest. This must be continued until breathing starts spontaneously, or in any event for at least an hour. As soon as the casualty starts to respond you should see an improvement in his colour, usually after the first dozen or so inflations. When breathing starts, it will be weak and shallow, and will still need assisting. Time your breaths to coincide with those of the casualty, as his breathing gradually strengthens. When breathing has restarted and can continue without help, the casualty will still be unconscious. He should be turned into the "unconscious" position, preferably with the body slightly higher than the head, and watched carefully to make sure that breathing continues. Don" t rush to get him to hospital. It is more important to make sure that breathing is strong and will continue while the casualty is being moved.

单选题What makes teenagers moody and impulsive? The answer used to be raging hormones plus a dearth of(短缺) life experiences. But three years ago this simple equation was blown apart by evidence from brain scans of strange goings-on behind the teenage forehead. Till then, scientists had thought the brain's internal structure was fixed by the end of childhood. The new scans showed the brain's frontal cortex(皮层) thickening just before puberty(青春期), then slowly shrinking back to normal during the teenage years. Suddenly, the erratic huffiness(发怒) seemed to make sense: the teenage brain was a work in progress, a house in the process of being rewired. Now comes more evidence of neural turmoil. According to psychologists in California, the speed with which youngsters can read the emotional expressions on people's faces dips suddenly at around the age of 11 or 12 and takes years to get back on track. The latest study, like the brain scan research before it, is a welcome and necessary part of building up a picture of a typical teenage brain so that scientists can get a better handle on what might be happening in the mental illnesses that appear to be afflicting children and adolescents in ever greater numbers. But there are dangers. Scientists still have no idea how to interpret the subtle changes seen in adolescent brain scans. Yet in the wrong hands, these findings could be used to justify hothousing, impulse control training and other dubious attempts to get the most out of malleable teenage brain cells. The science could also spark a new wave of moralising based on a perceived need to protect teenagers' evolving brain connections from evil or toxic influences. Incredibly, some scientists have already suggested in the press that the brain scan evidence somehow proves that it is biologically bad for teenagers to play video games or lie on the couch watching MTV. A hundred years, ago one well-known "expert" urged teenage boys to drink six to eight glasses of hot water a day to flush impure thoughts from their bodies. Have we really learned so little?

单选题Will fatherhood make me happy? That is a question many men have found themselves asking, and the scientific evidence is equivocal. A lot of studies have linked parenthood—particularly fatherhood—with lower levels of marital satisfaction and higher rates of depression than are found among non-parents. To investigate the matter further, psychologist Sonja Lyubomirsky decided both to study the existing literature, and to conduct some experiments of her own. The results suggest parenthood in general, and fatherhood in particular, really are blessings, even though the parent in question might sometimes feel they are in disguise. Dr. Lyubomirsky"s first port of call was the World Values Survey. This is a project which gathers huge amounts of data about the lives of people all around the planet. For the purposes of her research, Dr. Lyubomirsky looked at the answers 6,906 Americans had given, in four different years, to four particular questions. These were: how many children the responder had; how satisfied he (or she) was with life; how happy he was; and how often he thought about the meaning and purpose of life. She found that parents had higher happiness, satisfaction and meaning-of-life scores than non-parents. The differences were not huge, but they were statistically significant. Moreover, a closer look showed that the differences in happiness and satisfaction were the result of men"s scores alone going up with parenthood. Those of women did not change. Armed with this result, Dr. Lyubomirsky conducted her own experiment. The problem with projects like the World Values Survey is that, because participants are asked to recall their feelings rather than stating what they are experiencing in the here and now, this might lead them into thinking more fondly in hindsight about their parenting duties. Dr. Lyubomirsky therefore gave pagers to 329 North American volunteers aged between 18 and 94, having first recorded, among other things, their sex, age, ethnicity, socioeconomic status, marital status and number of children. She told them they would be paged at random, five times a day. When they were so paged, they were asked to complete a brief response sheet about how they felt, then and there. She did not, however, tell them why she was asking these questions. The upshot was the same as her findings from the World Values Survey. Parents claimed more positive emotions and more meaning in their lives than non-parents, and a closer look revealed that it was lathers who most enjoyed these benefits. It looks, then, as if evolution has bolted into men a psychological mechanism to keep them in the family. At first sight, it is strange that women do not share this mechanism, but perhaps they do not need to. They know, after all, that the children are theirs, and that a man"s potential to father an indefinite number of offspring if he can find willing volunteers, might encourage him to stray from the bosom of his family. Enjoying fatherhood, by contrast, will help keep him in the porch.
