And if he does go, it wont be the rage or the expense of liv

4、ing in the U.S. that drives him away. It will be the leaf blowers. Americans now own more than 90 million of the evil things, he says, each of them making the job of lawn clearing much easier and much, much louder. Rueter, a professor at UCLA who is head of the advocacy group Noise Free America, alr

5、eady fled Los Angeles to get away from the leaf-blower bother, only to move to New Orleans and find the problem just as bad there. “Everywhere has turned into leaf-blower hell.“ he says. Its not just the blowers that are driving Rueter daft. Its the boom cars those high-decibel(分贝 ), low-frequency s

6、peakers on wheels that cause your windshield to buzz and your eardrums to pulse when they pull up next to you at a stoplight. Its the car alarms too, as well as the barking dogs and the banging garbage trucks and the screaming airplanes and the roaring highways. Its the explosion of ambient(周围的 ) no

7、ise that seems to be everywhere, costing more and more people not only their sleep and their sanity but increasingly their hearing and health as well. According to the National Institutes of Health, more than 10 million Americans already suffer some permanent noise-induced hearing loss. They report

8、that some 30 million are exposed to daily noise levels that will eventually reduce their ability to hear. One in eight children between the ages of 6 and 19 already have some degree of hearing loss, and adults who are going deaf are doing so earlier and earlier. “The greatest increase in noise-relat

9、ed hearing loss occurs for people a5 to 64 years old,“ says Dr. James Battey, director of the National Institute on Deafness. “This is almost 20 years younger than we would expect.“ And its not just our ears the noise is hurting. It-takes sounds in excess of 85 db to damage hearing, but noise at les

10、s than 75 db may be linked to hypertension, and that at just 65 db leads to stress, heart damage and depression. Think the noise in your environment doesnt rise to that level? Think again. A ringing telephone can reach 80 db; a hair dryer hits 90 db; an ambulance siren can top out at 120 db. “Noise

11、pollution is truly a public health threat, “says Representative Nita Lowey of New York, who has reintroduced a bill in Congress to turn down the volume. “Its critical,“ she says, “that we work to diminish the impact noise has on our communities.“ The booming of America has many causes. Population gr

12、owth in city centers, loss of rural land to suburban sprawl, and the soaring number and size of cars on the highways all play a role. So too does the entertainment industry, with Walkmans, Pods and surround-sound theaters pouring noise into consumers cars. Even sports stadiums, always noisy places,

13、have got louder as earsplitting commercials fill the comparatively quiet interludes that used to prevail during pauses in the action. Whatever the roots of the problem, the noise is now everywhere and the workplace may be the worst place of all. At least 20% of US workers do their jobs in environmen

14、ts that could endanger their hearing, according to NIOSH. The US government estimates that more than 90% of coal miners suffer hearing impairment by age 50. Even farms are not exceptional: according to the New York Center for Agricultural Medicine and Health, a staggering 75% of farmers now exhibit

15、some hearing impairment, mostly as a result of noisy equipment. “Hearing loss is one of the most common workplace conditions, “says audiologist Ted Madison. For kids, the racket starts in the cradle. A squeaky toy held close to the ear which is precisely where babies may put them can reach 94 db. A

16、toy xylophone(木琴 ) can ring in at 92 db. And since babies car canals are so small, a sound that gets in them may knock around harder than it docs in an adults ears and do comparably more damage. Noise can be controlled to an extent, depending on the source. Some of the biggest sources of ambient noi

17、se are highways and roads, but the cause is less honking(使鸣响 ) horns or gunning engines though those play a role than tires hitting pavement, flexible rubber making contact with asphalt(沥青 ) doesnt seem as if it would produce a lot of noise but in fact it does. As any spot on the tire strikes the hi

18、ghway, it hits with the trunk of a little rubber hammer. Also, the patch of tire thats in contact with the ground at any instant the so-called tread block an squeak like a sneaker on a gym floor. Air pumping through tire grooves makes noise of its own. The solution, says engineer Bob Bernhard, is to

19、 change not the tires but the road surface. “You can make the pavement porous,“ he says,“ which affects the air-pumping mechanism. You can also mix a little rubber in with the asphalt, which changes the roads stiffness. “Porous surfaces are already being rolled out in parts of Georgia, Florida and A

20、rizona, as well as in Europe. Road noise that cannot be eliminated can be covered. More and more highways are being framed by high walls, additions that do little for the view but an awful lot for the peace and quiet of the people living nearby. The walls reduce noise by either reflecting or absorbi

21、ng it. This low-tech though pricey fix about $1 million a mile educes sound levels only as much as 7 db, but given the exponential way noise propagates, thats a lot. “A 10-db reduction may work out to a halving of loudness,“ says Nicholas Miller, head of Harris Miller the lip-reader has to stop eati

22、ng, stop reading, stop washing up, stop mending, stop everything in order to concentrate on hearing. It is not a question of stupidity or had temper as it sometimes appears to be but a question of being very easy to misunderstand when the sound is distorted. Remember what its like trying to communic

23、ate on a very bad telephone line. Frustrating, isnt it? The deaf have to face that all the time. A useful way of looking at the problem is to see the deaf as a foreigner to treat them as if you were in a foreign country. You would speak more clearly, slowly and raise your voice slightly. And youd us

24、e gestures to make your meaning clear, as well as have no hesitation in using pencil and paper to be absolutely certain. You can do all those things with the deaf as well as making sure you dont obscure your mouth with your hand, a pipe or a cigarette. Another point quite often overlooked is that a

25、heating aid may be quiet efficient and useful in a quiet carpeted room but try it in the high street in the rush hour, in a noisy car, in a railway station ticket office, a cinema or a concert hall and youve got a really difficult problem to distinguish speech. So dont suggest to or encourage deaf p

26、eople to go to functions(重大聚会 ) which are going to make their disability appear worse and increase their sense of failure. On the other hand careful selection of cinemas with good sound systems is important and you should experiment to find out where the best seats are for hearing, fitting adaptors

31、 58 At the Kyoto conference on global warming in December 1997, it became abundantly clear how complex it has become to work out international agreements relating to the environment because of economic concerns unique to each country. It is no longer enough to try to forbid certain activities or to

32、reduce emissions of certain substances. The global challenges of the interlink between the environment and development increasingly bring us to the core of the economic life of states. During the late 1980s we were able, through international agreements, to make deep cuts in emissions harmful to the

33、 ozone layer. These reductions were made possible because substitutions had been found for many of the harmful chemicals and, more important, because the harmful substances could be replaced without negative effects on employment and the economies of states. Although the threat of global warming has

34、 been known to the world for decades and all countries and leaders agree that we need to deal with the problem, we also know that the effects of measures, especially harsh measures taken in some countries, would be nullified(无效的 ) if other countries do not control their emissions. Whereas the UN tea

35、m on climate change has found that the emissions of carbon dioxide would have to be cut globally by 60% to stabilize the content of CO2 in the atmosphere, this path is not feasible for several reasons. Such deep cuts would cause a breakdown of the world economy. Important and populous low-income or

36、medium-income countries are not yet willing to undertake legal commitments about their energy uses. In addition, the state of world technology would not yet permit us to make such a big leap. We must, however, find a solution to the threat of global warming early in the 21st century. Such a commitme

37、nt would require a degree of shared vision and common responsibilities new to humanity. Success lies in the force of imaginations, in imagining what would happen if we fail to act. Although many living in cold regions would welcome the global-warming effect of a warmer summer, few would cheer the ar

38、rival of the subsequent tropical diseases, especially where there had been none. 58 It can be inferred that since the Kyoto conference, we find _. （ A） global warming problem is closely related to economy development （ B） global warming has produced various economy problems around the world （ C） dif

39、ferent countries have different views on the effect of global warming （ D） global warming has greatly affected the worldwide economy development 59 The difficulty in solving the problem of global warming lies in the fact that _. （ A） not all the countries are willing to make deep cuts in emissions （

40、 B） the leaders of many countries are reluctant to reach an agreement （ C） people in many areas dont realize the seriousness of the problem （ D） world technology is not able to solve the problem 60 Cutting carbon dioxide emission by 60% will _. （ A） be reached when low-income countries agree to reac
