2、elevision companies. Many television companies have used sports to attract viewers from particular sections of the general public, and then they have sold audiences to advertisers.An attraction of sport programs for the major U.S. media companies is that events are often held on Saturday and Sunday

3、afternoons the slowest time periods of the week for general television viewing. Sport events are the most popular weekend programs, especially among male viewers who may not watch much television at other times during the week. This means the television networks are able to sell advertising time at

4、relatively high prices during what normally would be dead time for programming.Media corporations also use sports to attract commercial sponsors that might take their advertising dollars elsewhere if television stations did not report certain sports. The people in the advertising departments of majo

5、r corporations realize that sports attract male viewers. They also realize that most business travelers are men and that many men make family decisions on the purchases of computers, cars and life insurance.Golf and tennis are special cases for television programming. These sports attract few viewer

6、s, and the ratings (收视率) are unusually low. However, the audience for these sports is attractive to certain advertisers. It is made up of people from the highest income groups in the United States, including many lawyers and business managers, This is why television reporting of golf and tennis is s

7、ponsored by companies selling high-priced cars, business and personal computers, and holiday trips. This is also why the networks continue to carry there programs regardless of low ratings. Advertisers are willing to pay high fees to reach high-income consumers and those managers who make decisions

8、to buy thousands of “company cars” and computers. With such viewers, these programs dont need high ratings to stay on the air.41. Television sport programs on weekend afternoons _. A. result in more sport events B. get more viewers to play sports C. make more people interested in television D. bring

9、 more money to the television networks42. Why would weekend afternoons become dead time without sport programs? A. Because there would be few viewers. B. Because the advertisers would be off work. C. Because television programs would go slowly. D. Because viewers would pay less for watching televisi

10、on.43. In many families, men make decisions on _. A. holiday trips B. sports viewing C. televisions shopping D. expensive purchases44.

One solution to this problem is to put the drugs inside a capsule, protecting them from the bodyand the body from themuntil they can be released at just the right spot. There are

13、lots of ways to trigger(引发) this release, including changing temperature, acidity, and so on. But triggers can come with their own risksburns, for example. Now, researchers in California have designed what could be a harmless trigger to date: shining near-infrared light (NIR,近红外线) on the drug in the

14、 capsule.The idea of using light to liberate the drug in the capsule isnt new. Researchers around the globe have developed polymers (聚合物) and other materials that begin to break down when they absorb cither ultraviolet (UV,紫外线) or visible light. But tissues also readily absorb UV and visible light,

15、which means the drug release can be triggered only near the skin, where the light can reach the capsule. NIR light largely passes through tissues, so researchers have tried to use it as a trigger. But few compounds(化合物) absorb NIR well and go through chemical changes.That changed last year when Adah

16、 Almutairi, a chemist at the University of California, San Diego, reported that she and her colleagues had designed a polymer that breaks down when it absorbs NIR light. Their polymer used a commercially available NIR-absorbing group called o-nitrobenzyl (ONB). When they catch the light, ONB groups

17、fall off the polymer, leading to its breakdown. But ONB is only a so-so NIR absorber, and it could be poisonous to cells when it separates from the polymer.So Almutairi and her colleagues reported creating a new material for capsules thats even better. This one consists of a long chain of compounds

18、called cresol groups linked in a polymer. Cresol contains reactive(易反应的) components that make it highly unstable in its polymeric form, a feature Almutairi and her colleagues use to their advantage. After polymerizing the cresols, they cap each reactive component with a light-absorbing compound call

19、ed Bhc. When the Bhcs absorb NIR light, the reactive groups are exposed and break the long polymer into two short chains. Shining additional light continues this breakdown, potentially releasing any drugs in the capsule. Whats more, Almutairi says, Bhc is 10 times better at absorbing NIR than is ONB

20、 and is not poisonous to cells.63. According to the passage, which of the following could be the best trigger?A. Temperature change. B. NIR light.C. Acidity change. D. UV light.64. Why in ONB unsatisfactory?A. It breaks down when it absorbs NIR light.B. It falls off the polymer and triggers drug rel

But there is another factor that can cause your heart problems more immediately: the air you breathe.Previous studies have linked high ex

26、posure(暴露) to environmental pollution to an increased risk of heart problems, but two analyses now show that poor air quality can lead to heart attack or stroke (中风) within as little as a few hours after exposure. In one review of the research, scientists found that people exposed to high levels of

27、pollutants (污染)were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA) considers to be of moderate (良好) quality and relatively safe for our

28、 health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure.The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to

29、 be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.53. The text mainly discusses the relations

30、hip between A. heart problems and air quality B. heart problems and exercisingC heart problems and smoking D. heart problems and fatty food54.
