听力练习题(中篇填空)01 文本 Depression is more than just feeling sad. It is a serious disease. Depression can interfere with normal life and a person’s sense of self-worth. It can end in suicide. (1)Some people are helped with traditional treatments, such as medicine or talking with mental health experts. Yet these treatments are not 100 percent effective. Luckily, there are other methods people can try. One such treatment involves bursts of electromagnetic energy. It sends magnetic pulses directly to the brain. Sonya Kibbee is from Columbia, Missouri. She works as a physical therapist. Kibbee says she is normally active, (2)but because of severe depression last year, she had trouble making simple decisions. People suffering from depression often seem to lack energy or interest in the things around them. (3)Depression affects how much a person eats and can interfere with sleep. Even with medication and talking with mental health professionals, Kibbee said, she thought about suicide. Doctors ordered hospital stays for her several times. Then she heard about TMS, short for Transcranial Magnetic Stimulation. TMS does not involve doctors operating on the patient. And the treatment usually does not require anesthesia. (4)TMS uses a wire to send powerful magnetic pulses to the brain. During the treatment, patients feel gentle, repeated beats on their head. The treatment can cause minor pain inside the head. So before her treatments, Kibbee took pain medicine, which reduced the sensation. After one week, she said she noticed a real difference. (5)After more than 30 treatments, her signs of depression almost disappeared. Doctor Muaid Ithman directs the TMS program at University of Missouri Health Care. He says the treatment can help patients when other methods do not. The United States National Institute of Mental Health has reported on two large studies on the safety of TMS. (6)It said they found that most side effects, such as head pain, were minor to moderate. However, the treatment is relatively new. The institute added that long-term side effects are unknown, and more studies are needed. As for Kibbee, she returned to work and some of her favorite activities.

Dictation.01 Old Age Many people mistakenly believe that old age is a time of increased illness and loneliness. In fact, people do not suddenly change when they reach the age of 60 or 65. Consequently, we should not expect more mental illness among the 60 to 70 age group than among the 50 to 60. Furthermore, although more parents and their married children lived in separate households than ever before, this is usually by choice. It is not because children now tend to neglect their parents when they become old. It is also wrong to believe that old age seriously affects a person’s mental abilities. There is clear proof that people who were eager to learn and who welcomed new experiences in their middle age, continue to do so in old age. It is true that older people tend to take longer to learn something new than young people. Nevertheless, if they are given sufficient time, they learn as well as young people do.

Dictation.02 Being Unemployed Most people are much more frightened by being unemployed than they need to be. Being unemployed certainly has disadvantages, but there are good things about it too. One advantage is that you don’t have to get up early to work in the rush hour. You can stay in bed as long as you like, and there is plenty of time to read the newspaper and have a leisurely breakfast. But the best thing of all is that you are your own boss and there is no one to tell you what to do and when to do it. One drawback of being unemployed is that you haven’t got much money coming in – having a job at least enables you to save a lot of money to go on holiday. On other hand, when you are unemployed, you needn’t go on holiday because you are on holiday already. In fact, the main trouble is that you have to spend much time looking for a job.

BBC Learning English The English We Speak 7 May 2013 Six-pack Finn: Ahh, this is the life. Sun shining, birds singing - beautiful day here in the park, eh Feifei? Feifei: Ah yes, fantastic. Just one thing, Finn. I'm a bit thirsty. Finn: Yes I could do with a drink. Feifei: An orange juice would be magnificent. Finn: No, no, no. On a day like today the ideal thing would be… an ice-cold beer, or maybe six… Looks in bag Finn: Ah – here we are. A six-pack! Look. Feifei: Finn, I don't really want to see your six-pack. Finn: What? Feifei: Actually, you don't have a six-pack. You have a beer belly! Finn: Oh, I get it! Very good, Feifei. In English the phrase six-pack originally refers to a way of selling cans of beer – buying six cans joined together with plastic holders. Feifei: And now, as a slang expression, it can also describe the shape of stomach muscles... on people who are very fit you can see six round muscles – which looks like a six pack of drink. Unfortunately, not on you Finn. Finn: What are you saying? Feifei: Anyone can see you don't have a six-pack. You have a one-pack – one huge beer belly! Finn: Well, I think that phrase is easy enough to understand. Feifei: Too many six-packs of beer, I'm afraid! Examples I've been going to the gym for a month now. I need to get my six-pack ready before I go to the beach this summer! The English We Speak © British Broadcasting Corporation 2013 Page 1 of 2 bbclearningenglish.com

I used to have a six-pack when I was a teenager, but it seems to have got lost under all this fat. Feifei: So Finn, how about you leave that six-pack of beer and swap it for... a healthy fruit smoothie! Finn: Nice idea, and I can see a fruit smoothie seller over there! I'll go and buy two. See you in a bit. Feifei: Thanks Finn. While he's over there let me remind everyone if you want to learn more phrases like six-pack and beer belly, check out bbclearningenglish.com.

BBC LEARNING ENGLISH The English We Speak A face for radio This is not a word-for-word transcript Yang Li Hello and welcome to the English We Speak from BBC Learning English. I'm Li. Neil… Hey, where is Neil? Although he's great presenter he's often late. Oh, here he comes! Neil Sorry, sorry Li, I'm here now. Sorry, I'm a bit late. Yang Li Wow Neil, you look so different today: a suit and tie – what's happening? Neil Well, I have to present our video: 'The Perfect English Gentleman' it's called. Yang Li That sounds fun. Don't you want to do it? Neil Not really. Yang Li Why not? You are a great presenter. Everyone loves your voice. Neil Well, it's not my voice that's the problem. Look at this massive, broken nose and spotty skin, my missing teeth, and long greasy hair… Li, I'm pretty ugly. I kept saying to my boss that I have a face for radio, but he insisted I present the video. What can I do? Yang Li Did you say you have a face for radio? But you don't need to show your face as a radio presenter, do you? Neil That's exactly the point, Li. If you say someone's got a good face for radio, it's an indirect way of saying they are not very good looking!

Yang Li I see. I like this phrase 'a face for radio' – an indirect way of saying someone is not very attractive. Here are some examples: Examples Man: Jane looked beautiful at her wedding. Woman: Really? She must have had a good make-up artist because, to be honest, she's got a face for radio. Man: No one's going to choose me at this speed-dating event. Woman: Why on earth not? You're such a warm-hearted guy. Man: Thanks. But you have to admit, I've got a face for radio. Yang Li So that's 'a face for radio' – our expression today. Hey Neil, I think I have got a solution for your video presenting problem… How about this for a good opening line? Do you want to hear it? Neil Go on then. Yang Li (clearing her throat): 'This modern English gentleman has got a face for radio. Just shut your eyes, relax and listen…' Neil Now you're making fun of me, Li! Yang Li OK, seriously, I think you will be just as good on video as you are in front of a microphone. You have a unique way of saying things which is clear, funny and engaging. What face could beat that! Neil Thanks Li. I feel a lot more confident now! Just pass me that mirror… Actually I'm not that bad looking, am I? Yang Li No, you're not. You've got a face for TV and a voice for radio! Neil Hey, thanks Li, you've made my day! Both Bye! The English We Speak ©British Broadcasting Corporation 2015 bbclearningenglish.com Page 2 of 2

课后阅读 01 Most of America’s landscape is rural, but journalists don’t go there very often. By Margaret Sullivan | September 10, 2017 1. Washington journalists may be obsessed with President Trump’s Russia connections. Silicon Valley reporters may be focused on the next big tech merger. And New York media types may be hyperventilating about Vanity Fair magazine’s editor stepping down. 2. But while most American journalists stay inside their urban bubble, the Texas Observer’s staff is laboring in the fields. Poisonous crop-dusting is on their minds. So are the wildfires that result when agricultural land goes fallow. And so are the many communities that don’t have a hospital within several hours’ drive – or even a nearby doctor. “There are such fantastic stories to be found,” said Forrest Wilder, editor of the Austin-based Observer, which recently became a mostly digital operation, still publishing in print six times a year. 3. Now, with funding from the Emerson Collective, the group founded by Laurene Powell Jobs, the Observer has added a full-time rural reporter, Christopher Collins, to its newsroom staff of about a dozen. The Observer will supplement his work with a network of freelancers. “We’re going to really look for stories in far-flung, underreported – or unreported – areas,” Wilder said. There are plenty of opportunities: 3.8 million of some 25 million Texans live in rural areas, he said. 4. The underreporting in rural areas is a nationwide phenomenon, with an increasing number of journalists clustered in New York, Washington and on the West Coast. And as metro dailies shrink their staffs, rural bureaus are often one of the first casualties, said Al Cross, who runs the Institute for Rural Journalism and Community Issues at the University of Kentucky. “Larger regional papers used to do this as a public service even though there was no advertising base for it,” Cross told me. Now, with less revenue coming in as a result of print advertising’s sharp decline, and with year after year of newsroom buyouts taking their toll, rural reporting has taken a hit. “It’s triage,” Cross said of newsroom decisions about what to cover. Rural reporting rarely is seen as the most critical mission. 5. But that leaves huge swaths of the United States without coverage. And the buying-up of small papers by chains, more beholden to stockholders than to local concerns, has hollowed out the journalism even more. The term “news deserts” aptly describes the results: In many communities, there’s no one to cover government meetings, hold officials accountable, or report on events, large or small. 6. That’s a real problem. Consider the succinct question raised on the Kentucky institute’s website: “Why is rural journalism important?” According to recent U.S. Census data, the vast majority of land in the United States is rural and contains about 20 percent of the nation’s population. 7. After the presidential election, the national media’s consciousness was raised on the importance of covering what some have considered “flyover country,” and some

页码 2

课后阅读 01 news organizations put more resources behind that coverage. (The Washington Post’s expanded “America desk” is one example.) 8. But coverage that is firmly rooted in a region has its own value, noted Wilder, who grew up in small-town Texas, as did Collins, the Observer’s new hire. “A reporter going in for a few days is important, but we wanted somebody who’s out there all the time, and who can approach the subject as something they have lived themselves,” he said. 9. Many community newspapers have managed to hang on, despite the changes in the newspaper business, said Tommy Thomason, director of the Texas Center for Community Journalism at Texas Christian University in Fort Worth. “These are the papers that nobody has heard of, but that do such important work,” he said. “Some of these small-town officials think they’ve been elected as deities.” 10. He tells the journalists who come in for midcareer training that they have a crucial mission: “If you’re not doing it, nobody is doing it.” Many of these papers have a single newsroom employee or, more typically, four or five. (Compare this with the New York Times with well over 1,000 newsroom employees, or a metropolitan daily where the staff might be around 100.) 11. Accountability reporting in small towns, just as in Washington, often meets with resistance – which explains the title of a book Thomason co-wrote on community journalists: “You Might Want to Carry a Gun.” 12. Some of that journalism is world-class, as the 10-person staff at the 3,000-circulation Storm Lake Times in Iowa ably proved: Their work on pollution resulting from agricultural changes won a Pulitzer Prize for editorial writing this year. 13. Big-city reporting – on politics, government, Wall Street and technology – is indispensable. But so is its oft-neglected rural counterpart. (767words from washingtonpost.com)

Passage 1 Why You Shouldn’t Work off the Clock 1. If you’re like a lot of American workers, you’re no stranger to staying late at the office or responding to work emails well into the night. In fact, 81 percent of U.S. salaried employees report that they work outside of their standard work hours, with 29 percent doing it three or more days per week, according to a new survey from Harris Poll. 2. That might get very relevant later this year when new overtime rules go into effect. Starting on December 1st, employers will need to pay overtime to employees who earn less than $47,476 per year; specifically, the law will require that those employees be paid wages of time and a half for all hours over 40 worked in a week. 3. That’s going to be quite a change, because it will mean that millions of people will need to begin tracking their hours and will probably be restricted from working any overtime at all. And yet working outside of normal work hours is so ingrained in American workers that over 90 percent of the workers in that Harris Poll survey said they would continue to do so even if it were against company policy. 4. Working off the clock might seem like it should be an employee’s choice; after all, if you’re willing to put in unpaid time to catch up on work, make sure a project goes smoothly or ensure you don’t come in to find 100 emails waiting for you in the morning, why shouldn’t you be allowed to? But there are some really good reasons why you shouldn’t work off the clock. 5. It’s illegal. First and foremost, if you’re among the majority of people who the law says must be paid overtime, your company would be breaking the law by allowing you to work off the clock. It doesn’t matter if you’re doing that work voluntarily; you can’t waive your right to overtime. And if you just work the overtime anyway and don’t record it, that could get your employer into a lot of trouble later. You would have the legal right to claim back pay and penalties from your employer later on, even if you were “volunteering” the time originally. So letting people work off the clock, even if they want to, is a serious risk for employers. 6. It gives your employer bad information about your working capacity. Your manager needs to know what can reasonably be accomplished in your position in 40 hours, in order to make accurate decisions about budgeting, staffing levels and work priorities. If you’re secretly working off the clock and your manager plans your team’s workload around that level of productivity, what’s going to happen if you suddenly decide you don’t want to or can’t put in those extra hours anymore? Furthermore, by working off the clock, you’re potentially making it harder for your manager to increase the staffing on your team, because if all the work is getting done, the company has less incentive to spend money on a new hire. 7. It’s bad for your co-workers. If the rest of your co-workers are following the law and company policy and not working unauthorized overtime while you’re secretly

页码 2

making an exception for yourself, you’re going to throw off the expectations for everyone. Your manager is likely to wonder why your co-workers aren’t producing at the same levels that you are, and that can increase the pressure and stress on them. Plus, it’s going to be really bad for the person who replaces you when you move on at some point. That person will be burdened with an unrealistic workload because you set unrealistic expectations about how much could be done with the time available. 8. You deserve to be paid. Worker protections have been hard won. People fought – and in some cases even died – for your right to be paid fairly for the time you work. And you have agreed to provide a particular amount of work in exchange for money, not to sign over all your free time to your employer. 9. If you can’t realistically finish all your work in 40 hours, the solution isn’t to work off the clock and not tell your boss. Instead, in most cases you should talk with your manager about what you can and can’t get done and how you should be prioritizing things. And yes, in reality there are indeed some managers who will tell you to just find a way to get it all done, but good, reasonable managers will want you to raise the issue. (760 words)

Passage 2 How Many Calories We Burn When We Sit, Stand or Walk 1. There are many compelling reasons to get up out of your desk chair and stand more at work. But weight control is probably not one of them, according to a new study that precisely measured how many calories people burn during everyday office activities. The new study’s results suggest that engaging frequently in one type of activity while at work may help many of us avoid weight gain. But that activity is not standing up. 2. Most of us sit more than we should, and a majority of our sitting time occurs at work, since many modern professions are sedentary. Many of us spend six or seven hours tied to our desks each day. These long, uninterrupted periods of physical lethargy have been linked with increased risks for diabetes, heart disease, premature mortality and, not least, weight gain. 3. In response, many people have begun to look for ways to break up our sitting time. We download smartphone apps that chirp and tell us to stand up several times every hour. Health-minded supervisors organize walking meetings, in which employees discuss business while hoofing along hallways. And standing desks have also become popular. 4. Recent studies indicate that measures that get us off our seats can help us better regulate blood sugar and lessen the risks for diabetes and chronic disease. But more to the point, many of us are rising from our chairs in the hopes that sitting less will help keep our waistlines and nether quarters from spreading. 5. Surprisingly few studies, however, have closely tracked how many additional calories we burn if we stand up or walk around our offices. So for the new experiment, which was published this month in the Journal of Physical Activity and Health, researchers from the Physical Activity and Weight Management Research Center at the University of Pittsburgh rounded up 74 healthy volunteers. Most were in their mid-20s, of normal weight, and with some acquaintance with office life. 6. These volunteers were randomly assigned to four different groups. One group was asked to sit and type at a computer for 15 minutes and then stand up for 15 minutes, moving around and fidgeting as little as possible. Another group also sat for 15 minutes, but watched a television screen and didn’t type. Afterward, they immediately moved to a treadmill and walked for 15 minutes at a gentle, strolling pace. The third group stood up for 15 minutes and then sat down for 15 minutes. And the final group walked on the treadmills for 15 minutes and then sat. 7. Throughout, the volunteers wore masks that precisely measured their energy expenditure, which means how many calories they were using. Unsurprisingly, sitting was not very taxing. The volunteers generally burned about 20 calories during their 15 minutes of sitting, whether they were typing or staring at a television screen. More unexpected, standing up was barely more demanding. While standing for 15 minutes,

页码 2

the volunteers burned about 2 additional calories compared to when they sat down. It didn’t matter whether they stood up and then sat down or sat down and then stood up. The total caloric expenditure was about the same and was not sizable. Over all, in fact, the researchers concluded, someone who stood up while working instead of sitting would burn about 8 or 9 extra calories per hour. 8. But walking was a different matter. When the volunteers walked for 15 minutes, even at a fairly easy pace, they burned about three times as many calories as when they sat or stood. If they walked for an hour, the researchers calculated, they would incinerate about 130 more calories than if they stayed in their chairs or stood up at their desks, an added energy expenditure that might be sufficient, they write, to help people avoid creeping, yearly weight gain. 9. The upshot of this experiment is that if your goal is to control your weight at work, then “standing up may not be enough,” said Seth Creasy, a graduate student at the University of Pittsburgh and the lead author of the new study. You probably need to also incorporate walking into your office routine, he said. Maybe “put the printer at the other end of the hallway, or get up to walk to the water fountain every hour or so” instead of keeping a water bottle at your desk. “Brief periods of walking can add up to make a big difference” in energy expenditure, he said, while standing barely budges your caloric burn. 10. Of course, standing up almost certainly has other health benefits apart from weight management, Mr. Creasy said, including better blood sugar control and less back and shoulder pain associated with hunching in a chair all day. So don’t dismantle or abandon your stand-up desk just yet. But don’t expect it to counteract that extra cookie with lunch. (811 words)

Reading Passage 1 Should you rely on the snooze button? A few more minutes. When faced with the decision to hop out of bed or grab a luxurious few more minutes of sleep, which do you choose? Believe it or not, that one decision could make a world of difference in the rest of your day. About 85 percent of Americans use an alarm clock to wake up in the mornings, according to sleep researcher Till Roennenber in his book, “Internal Time.” And while there are no official numbers on snoozing, a quick survey of social media makes it clear that hitting the snooze button is a popular pastime. As to how the snooze button will affect your day, scientists have mixed opinions. A British study led by evolutionary psychologist Satoshi Kanazawa found that people who hit the snooze button in the mornings are actually more intelligent, more creative and happier than their up-and-at-’em peers. Kanazawa’s argument is that nothing in our evolution has prepared us for the use of the snooze button. Therefore, it takes someone with outstanding intelligence and creativity to learn how to use this modern invention and incorporate it into their daily lives. On the flip side are scientists who claim that hitting the snooze button will ruin your life, or at the very least your day. “I feel that the snooze button has got to be one of the worst things to ever happen to human sleep,” somnology researcher Jonathan Horowitz tells MNN. “The chances of you ‘snoozing’ and actually experiencing a meaningful rest are close to nil.” According to some sleep experts, your body gets confused when you allow yourself to dip in and out of sleep cycles in the morning. You could wind up feeling drowsier than you would have if you had just gotten out of bed after the first set of beeps. This grogginess may linger throughout the day, making you less productive, less likely to exercise and more likely to make poor food choices. “When hitting the snooze button, you are in fact confusing your body and mind, throwing yourself into a deeper state of drowsiness,” explains Horowitz. “The bodily waking process needs to be accommodated, not side-stepped ... therefore, when returning to what will be a light sleep for a brief period of time, you are putting your body back into a sleeping mode before waking it again. At that point your body won’t know what it wants, resulting in a sort of half-awakened state that is known as sleep inertia.” So is using the snooze button a sign of greater intelligence or the portent of a bad day? If you really want to take advantage of an extra morning snooze, the key, some experts say, is to use the snooze button strategically, to supplement a healthy sleep cycle. Focus your efforts on getting enough sleep each night and waking around the same time each day so that when your alarm goes off you feel rested. Then if you want to use the snooze button as an insurance policy while you stretch and enjoy a 1
