For many people, working out and alcohol are closely linked. Sports teams and training partners celebrate victories, bemoan defeats or mark the end of training sessions with a beer or three. Beer, in fact, provides a substantial portion of some exercisers' fluid intake after workouts. But whether exercise encourages people to drink and, likewise, whether drinking encourages people to exercise has been in dispute. Now new studies suggest that exercise may well influence when and how much people drink. Drinking may even affect whether people exercise, and, the findings suggest, the interplay between exercise and alcohol could be a good thing. Past studies have shown that people who exercise tend numerically also to be people who drink, and vice versa. But most of these previous studies had limitations. They relied, for instance, on people's ability to recall their exercise and drinking habits over the course of, say, the past year, which can be notoriously unreliable. They also rarely took into account participants' ages and gender, which affect how much people exercise and drink. What is the relationship between exercise and alcohol from the new studies? A. The interaction between exercise and alcohol are in dispute.B. Exercise may impact on how long and when people drink.C. The interaction between exercise and alcohol might be good.

Dr. Miller, Professor of Sociology at Washington University, has written numerous articles and books on the issues facing older Americans in our graying society for the past 15 years. Dr. Miller:Dr. Miller: Thank you for that introduction. Today, I’d like to preface my remarks with a story from my own life which I feel highlights the common concerns that bring us here together. Several years ago when my grandparents were well into their eighties, they were faced with the reality of no longer being able to adequately care for themselves. My grandfather spoke of his greatest fear, that of leaving the only home they had known for the past 60 years. Fighting back the tears, he spoke proudly of the fact that he had built their home from the ground up, and that he had pounded every nail and laid every brick in the process. The prospect of having to sell their home and give up their independence, and move into a retirement home was an extremely painful experience for them. It was, in my grandfather’s own words, like having a limb cut off. He exclaimed in a forceful manner that he felt he wasn’t important anymore. For them and some older Americans, their so-called “golden years” are at times not so pleasant, for this period can mean the decline of not only one’s health but the loss of identity and self-worth. In many societies, this self-identity is closely related with our social status, occupation, material possessions, or independence. Furthermore, we often live in societies that value what is “new” or in fashion, and our own usage of words in the English language is often a sign of bad news for older Americans. I mean how would your family react if you came home tonight exclaiming, “Hey, come to the living room and see the OLD black and white TV I brought!” Unfortunately, the word “old” calls to mind images of the need to replace or discard. Now, many of the lectures given at this conference have focused on the issues of pension reform, medical care, and the development of public facilities for senior citizens. And while these are vital issues that must be addressed, I’d like to focus my comments on an important issue that will affect the overall success of the other programs mentioned. This has to do with changing our perspectives on what it means to be a part of this group, and finding meaningful roles the elderly can play and should play in our societies. First of all, I’d like to talk about . . .7. A) There are no more irregular practices.B) All new cabs provide air-conditioning.C) New cabs are all equipped with meters.D) New legislation protects consumer rights.Section BDirections: In this section, you will hear two long conversations.

The market for products designed specifically for older adults could reach ﹩30 billion by next year， and startups（初创公司） want in on the action． What they sometimes lack is feedback from the people who they hope will use their products． So Brookdale， the country's largest owner of retirement communication， has been inviting a few select entrepreneurs just to move in for a few days， show off their products and hear what the residents have to say． That's what brought Dayle Rodriguez， 28， all the way from England to the dining room of Brookdale South Bay in Torrance， California． Rodriguez is the community and marketing manager for a company called Sentab． The startups product． Sentab TV， enables older adults who may not be comfortable with computers to access email， video chat and social media using just their televisions and a remote control． "It's nothing new， it's nothing too complicated and it's natural because lots of people have TV remotes．" says Roanguez． But none of that is the topic of conversation in the Brookdale dining room． Instead， Rodriguez solicits residents' advice on what he should get on his cheeseburger and how he should spend the afternoon Playing cards was on the agenda， as well as learning to play mahjong（麻将）． Rodriguez says it's important that residents here don't feel like he's selling them something． I've had more feedback in a passive approach． "he says， "Playing pool， playing cards， having dinner， having lunch， all work better than going through a survey of questions． When they get to know me and to trust me， knowing for sure I'm not selling them something -there'll be more honest feedback from them． Rodriguez is just the seventh entrepreneur to move into one of Brookdale's 1， 100 senior living communities． Other new products in the program have included a kind of full-body blow dryer and specially designed clothing that allows people with disabilities to dress and undress themselves． "First and foremost， the residents love it． "says Smith． "It also provides Brookdale the opportunity to learn about and experience new technologies quickly and inexpensively and to make sure that we understand what residents want and need． Mary Lou Busch， 93， agreed to try the Sentab system． She tells Rodriguez that it might be good for someone， but not for her． "I have the computer and Face time， which I talk with my family on． " she explains． She also has an ipad and a smart phone． "So I do pretty much everything I need to do． Rodriguez takes it pretty well． "I' m not going to lie to you， I would've liked a more positive response． " he says． But "if people don't need it or want it， it's up to us to change， adapt it or make it more useful． To be fair， if Rodriguez had wanted feedback from some more technophobic（害怕技术的） seniors he might have ended up in the wrong Brookdale community． This one is located in the heart of Southem Califomia's aerospace corridor． Many residents have backgrounds in engineering， business and academic circles． But Rodriguez says he's still learning something important by moving into this Brookdale community： "People are more tech-skilled than we thought． And besides， where else would he learn to play mahjong？（1）What does the passage say about the startups？___A． They want to have a share of the seniors' goods marketB． They try to profit from promoting digital products to seniors．C． They invite seniors to their companies to try their productsD． They never lose time in upgrading products for seniors（2）Some entrepreneurs have been invited to Brookdale to___A． show senior residents how to use IT productsB． have an interview with potential customerC． conduct a survey of retirement communitiesD． collect residents' feedback on their products（3）What do we know about Sentab TV？___A． It is a digital TV which enjoys popularity among seniorsB． It is a TV specially designed for seniors to view programs．C． It is a communication system via TV instead of a computerD． It is a TV program catering to the interest of the elderly（4）Which of the following best explains "solicits" underlined in Paragraph 4？___A， rejectsB． offersC． voicesD． seeks（5）What does Rodriguez say is important in promoting products？___A． Knowing the likes and dislikes of customersB． Responding promptly to customer feedbackC． Winning trust from potential customersD． Demonstrating their superiority on the spot（6）What do we learn about the seniors in the Brookdale community？___A． Most of them enjoy a longer life than average people．B． They are quite at ease with high-tech productsC． Most of them are interested in using the Sentab．D． They have much in common with seniors elsewhere

"Sugar, alcohol and tobacco," economist Adam Smith once wrote," are commodities which are nowhere necessaries of life, which have become objects of almost universal consumption, and which are, therefore, extremely popular subjects of taxation. "Two and a half centuries on, most countries impose some sort of tax on alcohol and tobacco. With surging obesity levels putting increasing strain on public health systems, governments around the world have begun to toy with the idea of taxing sugar as well.Whether such taxes work is a matter of debate. A preliminary review of Mexico's taxation found a fall in purchases of taxed drinks as well as a rise in sales of untaxed and healthier drinks. By contrast, a Danish tax on foods high in fats was abandoned a year after its introduction, amid claims that consumers were avoiding it by crossing the border to Germany to satisfy their desire for cheaper, fattier fare.The food industry has, in general, been firmly opposed to such direct government action. Nonetheless, the renewed focus on waistlines means that industry groups are under pressure to demonstrate their products are healthy as well as tasty.Over the past three decades, the industry has made some efforts to improve the quality of its offerings. For example, some drink manufacturers have cut the amount of sugar in their beverages.Many of the reductions over the past 30 years have been achieved either by reducing the amount of sugar, salt or fat in a product, or by finding an alternative ingredient. More recently, however, some companies have been investing money in a more ambitious undertaking: learning how to adjust the fundamental make-up of the food they sell. For example, having salt on the outside, but none on the inside, reduces the salt content without changing the taste.While reformulating recipes （ 配方） is one way to improve public health, it should be part of a multi-sided approach. The key is to remember that there is not just one solution. To deal with obesity, a mixture of approaches--including reformulation, taxation and adjusting portion sizes--will be needed. There is no silver bullet.What did Adam Smith say about sugar, alcohol and .tobacco?A.They were profitable to manufacture.B.They were in ever-increasing demand.C.They were subject to taxation almost everywhere.D.They were no longer considered necessities of life.Why have many countries started to consider taxing sugar?A.They are under growing pressure to balance their national budgets.B.They find it ever harder to cope with sugar-induced health problems.C.The practice of taxing alcohol and tobacco has proved both popular and profitable.D.The sugar industry is overtaking alcohol and tobacco business in generating profits.What do we learn about Danish taxation on fat-rich foods?A.It did not work out as well as was expected.B.It gave rise to a lot of problems on the border.C.It could not succeed without German cooperation.D.It met with firm opposition from the food industry.What is the more recent effort by food companies to make foods and drinks both healthy and tasty?A.Replacing sugar or salt with alternative ingredients.B.Setting a limit on the amount of sugar or salt in their products.C.Investing in research to find ways to adapt to consumers' needs.D.Adjusting the physical composition of their products.What does the author mean by saying, at the end of the passage, "There is no silver bullet" （ Line 4, Para.7）?A.There is no single easy quick solution to the problem.B.There is no hope of success without public cooperation.C.There is no hurry in finding ways to solve the obesity problem.D.There is no effective way to reduce people's sugar consumption..

* 本题备选项需点击原文空格处获取，在列表上点选即可。 Steel is valued for its reliability, but not when it gets cold. Most forms of steel (26)_____ become brittle (脆的) at temperatures below about -25°C unless they are mixed with other metals. Now, though, a novel type of steel has been developed that resists (27)_____ at much lower temperatures, while retaining its strength and toughness—without the need for expensive (28)_____. Steel’s fragility at low temperatures first became a major concern during the Second World War. After German U-boats torpedoed (用鱼雷攻击) numerous British ships, a 2700-strong fleet of cheap-and-cheerful “Liberty ships” was introduced to replace the lost vessels, providing a lifeline for the (29)_____ British. But the steel shells of hundreds of the ships (30)_____ in the icy north Atlantic, and 12 broke in half and sank. Brittleness remains a problem when building steel structures in cold conditions, such as oil rigs in the Arctic. So scientists have (31)_____ to find a solution by mixing it with expensive metals such as nickel. Yuuji Kimura and colleagues in Japan tried a more physical (32)_____. Rather than adding other metals, they developed a complex mechanical process involving repeated heating and very severe mechanical deformation, known as tempforming. The resulting steel appears to achieve a combination of strength and toughness that is (33)_____ to that of modern steels that are very rich in alloy content and, therefore, very expensive. Kimura’s team intends to use its tempformed steel to make ultra-high strength parts, such as bolts. They hope to reduce both the number of (34)_____ needed in a construction job and their weight—by replacing solid supports with (35)_____ tubes, for example. This could reduce the amount of steel needed to make everything from automobiles to buildings and bridges.
