3、ud Ted Rueter isnt joking about possibly moving to New Zealand. And if he does go, it wont be the rage 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 clear
4、ing much easierand much, much louder. Rueter, a professor at UCLA who is head of the advocacy group Noise 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.“
5、 he says. Its not just the blowers that are driving Rueter daft. Its the boom carsthose high-decibel(分贝 ), 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
6、and the banging garbage trucks and the screaming airplanes and the roaring highways. Its the explosion of 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 I
7、nstitutes of Health, more than 10 million Americans already suffer some permanent noise-induced hearing loss. 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 deg
8、ree of hearing loss, and adults who are going deaf are doing so earlier and earlier. “The greatest increase 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 expec
9、t.“ And its not just our ears the noise is hurting. It-takes sounds in excess of 85 db to damage hearing, but 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? Th
10、ink again. A ringing telephone can reach 80 db; a hair dryer hits 90 db; an ambulance siren can top out at 120 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,
11、 “that we work to diminish the impact noise has on our communities.“ The booming of America has many causes. 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
12、 Walkmans, Pods and surround-sound theaters pouring noise into consumers cars. Even sports stadiums, always noisy 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
13、 is now everywhereand the workplace may be the worst place of all. At least 20% of US workers do their jobs in 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 exc
14、eptional: according to the New York Center for Agricultural Medicine and Health, a staggering 75% of farmers now 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 s
15、tarts in the cradle. A squeaky toy held close to the earwhich is precisely where babies may put themcan reach 94 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
16、 more damage. Noise can be controlled to an extent, depending on the source. Some of the biggest sources of ambient 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 aspha
17、lt(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 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
18、gym floor. Air pumping through tire grooves makes noise of its own. The solution, says engineer Bob Bernhard, is to 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,
19、which changes the roads stiffness. “Porous surfaces are already being rolled out in parts of Georgia, Florida and Arizona, 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 aw
20、ful lot for the peace and quiet of the people living nearby. The walls reduce noise by either reflecting or absorbing 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 ma
21、y work out to a halving of loudness,“ says Nicholas Miller, head of Harris Miller and I spent years playing in bars throughout the South. In my mid-30s I moved to Nashville. After two years of hard work, I somehow managed to get a songwriting deal, and a record label was showing interest in me. Then
22、 my wife and I started having marital problems, and we moved to another state. The move was like driving the last nail in the coffin on my dream. It felt as if Id given up on myself. One day during a trip I made to Nashville, a friend offered me a hit of methamphetamine from a little pipe. I didnt k
23、now then that meth is our biggest drag problem in rural America that its the easiest, cheapest drug to obtain, and also one of the most addictive. So I smoked it. And that was all that I thought about for the next year and a half. I ended up with a one to two gram-a-day habit, at a hundred dollars a
24、 gram. When the police arrested me, I looked like death, and didnt care. My body was so beat up from doing drugs that my eyes were sunk back in my head, and my teeth and hair were failing nut from malnourishment ( 营养不良 ). The first seven days in jail, I just slept, going cold turkey(强制戒毒 ). When I w
25、oke up from the crash on the eighth day, I had never known such shame and guilt. I walked down the hall to the pay phone, dreading every step. My mama is the sweetest soul on the planet, and I knew this was going to break her heart. When I heard her voice I wasnt sure I could go through with it, but
26、 I told her where I was. She said, “Son, dont you know you cant do anything to make me not love you?“ Her words gave me the strength to turn to the God that I had denied. “I know Ive messed up,“ I prayed. “And Im not asking for anything, except tell me what Im supposed to do.“ For the first time I r
27、ealized that I couldnt blame anybody else for my trouble. And I also realized this was my chance to turn things around. The next day, I called the people Id taken things from and gave them the names of the pawn-shops where they could find their stuff. It was a small step toward making things right.
28、Counting rehab (戒毒所 ), I was in jail for 94 days, but only because the judge took pity on me. He said that what Id done seemed like a cry for help. The first thing I did when I got out was go to see Kenny Beard, my songwriting partner. He met me at the door holding the prized guitar hed used to writ
29、e so many hits, a guitar that Id hocked six months earlier. He stuck it in my chest and told me to get my writing deal back. His faith in me gave me the courage to stay straight. The executives at RCA, the record label that finally signed me, werent scared off by my history. They thought folks would
30、 relate to my songs. When people hear my words, I hope theyll see that were all human. I dont want them to make the same mistakes I have, but I do know that you can overcome almost anything, especially drug abuse. If sharing my story gives somebody a little courage to fight, then every bit of it was
31、 worth it. 55 Which of the following statement is NOT hue according to the passage? （ A） The author was sent to jail because he betrayed the value he believed in. （ B） The author resorted to stealing so as to satisfy his drag addict. （ C） The author might have experienced a tough childhood. （ D） The
32、 author was abandoned by his birth parents shortly after he was born. 56 The author was adopted since his childhood, so he _. （ A） left his step mother to try to find his birth parents （ B） resented his adoptive mother covering the truth （ C） was obsessed by the feeling of abandonment （ D） felt grat
33、eful for his adoptive parents 57 What is hue about the authors musical career? （ A） His talent was well recognized since he was a teenager. （ B） He wanted to regain his confidence by becoming a country music singer. （ C） His performances in the bars had proved successful. （ D） He moved to another ci
34、ty because the record label showed interest in him. 58 After calling his adoptive mother and learning he was still deeply loved by her, the author _. （ A） blamed fate for his misfortunes （ B） realized it was already too late to restart a new life （ C） still had a sense of abandonment （ D） saw it as
35、a chance to live a whole new life 59 What is NOT the authors attitude at the end of the story? （ A） Grateful. （ B） Encouraged. （ C） Hopeful. （ D） Skeptical. 60 Life on earth depends on water, and there is no substitute for it. The current assumption is that our basic needs for water-whether for drin
36、king, agriculture, industry or the raising of fish-will always have to be met. Given that premise, there are two basic routes we can go: more equitable(平衡的 ) access to water or more drastic engineering solutions. Looking at the engineering solution first, a lot of my research concentrates on what ha
37、ppens to wetlands when you build dams in river basins, particularly in Africa. The ecology of such areas is almost entirely driven by the seasonal regime of the riverthe pulse of the water. And the fact is that if you build a dam, you generally wreck the downstream ecology. In the past, such problem
38、s have been hidden by a lack of information. But in this century, governments will have no excuse for their ignorance. The engineers ability to control water flows has created new kinds of unpredictability too. Dams in Africa have meant fewer fish, less grazing and less floodplain(泛滥平原 ) agriculture
39、, none of which were anticipated. And their average economic life is assumed to be thirty years. Dams dont exist for ever, but what will replace them is not clear. The challenge for the next decade is to find new means of controlling water. Although GM technology will allow us to breed better dry-la
40、nd crops, there is no market incentive for companies to develop crops suitable for the micro-climates of the Sahel and elsewhere in Africa. Who is going to pay for research on locally appropriate crops in the Third World? This brings us to the key issue in any discussion of water: money. To talk abo
41、ut a water crisis covers difficult problems such as poverty. In the next decade every household in Britain will have a water meter, and we will pay for what we use just as we do for gas or electricity. That can be resolved and a similar system will eventually be adopted across Europe and the US. But
42、 consider the problems of water supply in Mexico City or Delhi. If youre rich, you drink mineral water and may even have a swimming-poolyet millions in such cities cant get safe drinking water. There is a coming water crisis which is one for the poor. 60 The word “premise“(Para. 1) probably means “_
43、“. （ A） assumption （ B） promise （ C） need （ D） crisis 61 The negative effect of engineering solution is that _. （ A） it costs a large amount of money which is not affordable （ B） the government worries about the quality of the water conservancy （ C） it destroys the habitat of plants and animals of t
44、hat area （ D） the government becomes more and more ignorant 62 It can be inferred from the passage that _. （ A） if dams were built in river basins, the downstream ecology remained the same （ B） governments have to be responsible for the changes caused by the constructions of dams （ C） the results of
45、 controlling water flows by engineers can be well forecasted （ D） a dam can bring economical advantages for almost a century 63 Companies dont want to spend money on research in developing appropriate crops in Africa because _. （ A） existing technology fails to grow dry-land crops （ B） only dozens o
46、f years later can they make profits （ C） they are not encouraged and probably cannot make any profit （ D） most of African countries belong to the third world 64 The authors attitude towards water crisis is _. （ A） concerned （ B） indifferent （ C） critical （ D） detached 三、 Part V Cloze (15 minutes) Di
47、rections: There are 20 blanks in the following passage. For each blank there are four choices marked A, B, C and D. You should choose the ONE that best fits into the passage. 64 For me, scientific knowledge is divided into mathematical sciences, natural sciences or sciences dealing with natural worl
48、d, and sciences dealing with mankind. Apart from these sciences is philosophy. All this is pure or【 C1】 _ knowledge, sought only for the【 C2】 _ of understanding in order to fulfill the need to understand what is intrinsic and consubstantial (同质的 ) to man. What【 C3】 _ man from animal is that he knows
49、 and needs to know. If man did not know that the world existed, and that the【 C4】 _ was of a certain kind, that he was in the world and that he himself was of a certain kind, he wouldnt be man. The technical aspects or applications of knowledge are equally necessary for man and are of the greatest importance,【 C5】 _ they also contribute to【 C6】 _ him as man and permit him to 【 C7】 _ a life increasingly more tr
