And if he does go, it wont be the rage
4、or the expense of living 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 easierand much, much louder. Rueter, a professor at UCLA who is head of the advocacy group Noi
5、se Free America, already 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 carsthose high-decibel(分贝)
6、, low-frequency speakers 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
7、 ambient(周围的) noise 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 los
8、s. They report 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
9、 in noise-related 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, bu
10、t noise at less 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 1
11、20 db. “Noise 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.
12、Population growth 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 n
13、oisy places, 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 everywhereand the workplace may be the worst place of all. At least 20% of US workers do their jobs in
14、 environments 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 n
15、ow exhibit 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 earwhich is precisely where babies may put themcan reach 9
16、4 db. A 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 ambie
17、nt noise are highways and roads, but the cause is less honking(使鸣响) horns or gunning enginesthough those play a rolethan 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
18、highway, it hits with the trunk of a little rubber hammer. Also, the patch of tire thats in contact with the ground at any instantthe so-called tread blockan 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 Ar
20、izona, 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 absorbing
21、 it. This low-tech though pricey fixabout $1 million a mileeduces 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 that is, they are excessively conce

26、 through carefully before making your choices. Each choice in the bank is identified by a letter. Please mark the corresponding letter for each item with a single line through the center. You may not use any of the words in the bank more than once.46 When the earth was born there was no ocean. The g

Each p
32、assage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice.57 Our bodies are wonderfully skilful at maintaining balance. When the temperature jumps, we sweat to cool down. When our blood pressure f
33、alls, our hearts pound to compensate. As it turned out, though, our natural state is not a steady one. Researchers are finding that everything from blood pressure to brain function varies rhythmically with the cycles of sun, moon and seasons. And their insights are yielding new strategies for keepin
34、g away such common killers as heart disease and cancer. Only one doctor in 20 has a good knowledge of the growing field of “chronotherapeutics,“ the strategic use of time (chronoa) in medicine. But according to a new American Medical Association poll, three out of four are eager to change that. “The
35、 field is exploding“, says Michael Smolensky. “Doctors used to look at us like, What space ship did you guys get off of? Now theyre thirsty to know more.“In medical school, most doctors learn that people with chronic conditions should take their medicine at steady rates. “Its a terrible way to treat
36、 disease,“ says Dr. Richard Martin. For example, asthmatics (气喘患者)are most likely to suffer during the night. Yet most patients strive to keep a constant level of medicine in their blood day and night,whether by breathing in on an inhaler (吸入器) four times a day or taking a pill each morning and even
37、ing. In recent studies, researchers have found that a large mid-afternoon dose of a bron chodilator (支气管扩张剂) can be as safe as several small doses, and better for preventing night-time attacks.If the night belongs to asthma, the dawn belongs to high blood pressure and heart disease. Heart attacks tw
38、ice as common at 9 a. m. as at 1l p. m. Part of tile reason is that our blood pressure falls predictably at night, then peaks as we start to work for the day. “Doctors know that“, says Dr. Henry Black of Chicago Medical Center,“ but until now, we havent been able to do anything about it. “Most blood
39、 pressure drugs provide 18 to 20 hours of relief. But because theyre taken in the morning, theyre least effective when most needed. “You take your pill at 7 and its working by 9,“ says Dr. William White of the University of Connecticut Health Center. “But by that time youve gone through the worst fo
40、ur hours of the day with no protection,“ Bedtime dosing would prevent that lapse, but it would also push blood Pressure to dangerously low levels during the night.57 According to the passage, how do human bodies maintain balance?（A）They adjust themselves timely in line with their physical conditions
41、.（B） People increase or lower the body temperature by sweating.（C） Peoples hearts pound to compensate when the blood pressure goes up.（D）Our natural state is not a steady one.58 Researchers are finding that _.（A）heart disease and cancer are the most common killers of human beings（B） blood pressure a
42、nd brain function are decided by cycles of sun, moon and seasons（C） the functions of human bodies have much to do with nature（D）any change in human bodies goes systematically with changes in the environment59 According to the author, it is best for asthmatics to take their medicines _.（A）at steady r
43、ates（B） each morning and evening（C） when the disease occurs（D）at mid-afternoon60 Which of the following statements is TRUE according to Para. 1?（A）Doctors know less about chronotherapeutics than before.（B） Doctors in the U. S. used to be thirsty to know more about the new medical field.（C） The resea
44、rchers insights are providing new strategies to cure common killers.（D）The strategic use of time in medicine attracts more attention in the medical circle in the U.S.61 According to the passage, which of the following is the most important?（A）Medicine.（B） Treatment.（C） Timing.（D）Prevention.61 By edu
45、cation, I mean the influence of the environment upon the individual to produce a permanent change in the habits of behavior, of thought and of attitude. It is in being thus susceptible to the environment that man differs from the animals, and the higher animals from the lower. The lower animals are
46、influenced by the environment but not in the direction of changing their habits. Their instinctive responses are few and fixed by heredity. When transferred to an unnatural situation, such an animal is led astray by its instincts. Thus the ant-lion whose instinct implies it to bore into loose sand b
47、y pushing backwards with abdomen, goes backwards on a plate of glass as soon as danger threatens, and endeavors, with the utmost exertions to bore into it. It knows no other mode of flight or if such a lonely animal is engaged upon a chain of actions and is interrupted it either goes on vainly with
48、the remaining actions (as useless as cultivating an unsown field) or dies in helpless inactivity. Thus a net-making spider which digs a burrow and rims it with a bastion of gravel and bits of wood, when removed from a half finished home, will not begin again, though it will continue another burrow,
49、even one made with a pencil.Advance in the scale of evolution along such lines as these could only be made by the emergence of creatures with more and more complicated instincts. Such beings we know in the ants and spiders. But another line of advance was destined to open out a much more far-reaching possibility of which we do not see the end perhaps even in man. Habits, instead of being born ready-m
