    阅读新视界大学英语第五单元课文,完成以下练习。 Leisure inactivities – or how to relax and do nothing 1 Centuries ago people didn’t have much free time, because everyone was working too hard. In Britain in the 19th century, people had more free time, but the Victorians thought relaxing and doing nothing was a sin. So to avoid temptation, they invented football and cricket. People took up more gentle leisure activities like bird-watching, and gardening, and it was even possible simply to watch a sport and be satisfied that you were actually doing something useful. 2 One instance of this is cricket, which is a peculiar game with weird rules, where nothing happens for five days, at the end of which the players often decide to call it a draw. And everyone playing or watching feels perfectly fulfilled by this non-event. It’s a good example of what we now call a leisure inactivity. 3 Gradually over the years, leisure inactivities have involved even less interaction. In the 1990s a new leisure creature evolved, one who thinks that lying on the sofa watching sport or DVDs on the television is the most exciting inactivity they can manage. This is the couch potato. 4 So who wants to be a couch potato? Well, as a matter of fact, many people do, and for very good reasons. Maybe it’s your one day off in the week, maybe you just got back from work or school. Maybe you’re tired and just want to chill. For the couch potato, every activity is too much trouble, and being idle is an art form. 5 How do you become a couch potato? It’s easy. Sit down in a comfortable place, such as a nice soft chair, or ... you knew it was coming ... a couch. Don’t sit on a potato. Make sure you have everything you need, things to eat (especially potato chips – no serious couch potato would eat anything else), drinks, magazines and a telly. 6 The most important piece of equipment is of course, the remote control. Without the freedom to change channels without moving from the couch, no couch potato would be worthy of the name. In fact, watching TV without a remote control becomes dangerously like physical exercise, and probably should be avoided. 7 Now just start watching the telly. Change channels every ten seconds, and then move on. Try your best to lose concentration quickly, in order to maintain your status as a couch potato. (Remember that you also have the attention span of a potato.) Finally, ask other people to do things for you, like get more food, or rent a movie. But be nice to them! If you aren’t nice, you’ll probably have to do it yourself. 8 But with every new trend, there’s a reaction. British farmers were recently reported by the BBC to be angry at the use of the expression couch potato, because it gave the vegetable a negative image. Potatoes are inherently healthy, says the British Potato Council, and is organizing protests to demand the removal of couch potato from the Oxford English Dictionary. 9 So there you are! Couch potatoes are healthy. 10 Of course, for the true couch potato, there are inherent risks. Perhaps the greatest of these results from the lack of exercise, and is referred to by professional couch potatoes as telly belly. Some, however, see their telly belly as a mark of their commitment to their leisure inactivity, and wear it proudly over the top of their trousers. (Interestingly, this is a highly fashionable style known as a muffin top. Find out why next time you’re in Starbucks.) 11 But time moves on, and in the 21st century we now have a version of the couch potato specially for the online activities on the computer. This is called the mouse potato. A mouse potato spends excessive amounts of time in front of a computer monitor, with the same absence of interest in the outside world as their older cousin, the couch potato. Mouse potatoes are hooked on online games with other fellow potatoes around the world. In fact, leaving the computer not only lacks purpose but also risks a threat by some rival or more skilful mouse potato in a brighter time zone across the world. For time off, their routine includes performing extensive Internet searches or participating in online chat rooms, leaving ill-informed and badly spelt opinions around the virtual world, causing offence or generally insulting one’s intelligence. 12 For mouse potatoes with an aspiration for adventure, you can even travel the world and visit countries you might otherwise never see by going to CouchPotatotravel.com. You can also find out how much time you spend on your computer by logging the distance your mouse travels. These are called mouse miles, and who knows, maybe one day you can exchange them for more potato chips at all good computer stores. 13 So with a minimum of effort you too can have your own leisure inactivity. Become a couch potato! Earn that telly belly! Train hard as a mouse potato, and earn mouse miles. Get started today. There’s so much time, and so little to do.

    Why do smokers tend to weigh less than nonsmokers and gain weight when they give up the habit? Contrary to “common knowledge”, nonsmokers do not generally eat more than smokers, nor do they exercise less, studies find. Research performed on smokers at rest indicates that nicotine (尼古丁) itself can increase basal metabolic (新陈代谢的) rates, meaning smokers burn more energy than nonsmokers during periods of inactivity. But surveys suggest most smokers smoke not while completely at rest, but while performing light activities such as desk work that can increase metabolic rates by two or three times. Unless nicotine’s metabolic effects increase proportionally with metabolic rates, its influence on weight might be insignificant. Now a study shows that nicotine’s effects on body-fuel consumption indeed increase proportionally with increases in activity. “These results indicate that the metabolic effect of nicotine may play a greater part in accounting for body-weight differences between smokers and nonsmokers than was previously believed,” says Kenneth A. Perkins and his colleagues at the University of Pittsburgh School of Medicine. The researchers gave a nicotine nose spray to individuals performing light work — in this case riding an exercise bicycle modified to allow easy riding while subjects remain seated in a comfortable armchair. The activity raised resting metabolic rates two to three times. By analyzing air breathed out, the researchers calculated energy consumption in the armchair bicyclists before and after giving the nose spray and compared the relative changes with subjects in the control group given placebo ((试验药物用的)无效对照剂) nose sprays. Relative to their baseline bicycle expenditures, individuals in the nicotine group expended considerably more energy than did those in control group while doing the same amount of work. With nicotine, Perkins says, “It’s as if the body is becoming much less efficient in using its stored energy.” While the results may seem discouraging to smokers who’d like to quit without gaining weight, Perkins notes that walking an extra mile a day should make up for the difference in metabolic efficiency. And he says smokers would have to gain “well more than 50 pounds” to counterbalance the health risks of continued smoking.

    Directions: In this section, you are going to read a passage with ten statements attached to each statement contains information given in one of the paragraphs. Identify the paragraph from which the information is derived. You may choose a paragraph more than once. Each paragraph is marked with a letter.How Work Will Change When Most of Us Live to 100A) Today in the United States there are 72,000 centenarians(百岁老人).Worldwide, Probably 450,000. Ifcurrent trends continue, then by 2050 there will be more than a million in the US alone. According to the work ofProfessor James Vaupel and his co-researchers, 50% of babies born in the US in 2007 have a life expectancy of104 or more. Broadly the same holds for the UK, Germany, France, Italy and Canada, and for Japan 50% of 2007babies can expect to live to 107.B) Understandably, there are concerns about what this means for public finances given the associated health andpension challenges. These challenges are real, and society urgently needs to address them. But it is also importantto look at the wider picture of what happens when so many people live for 100 years. It is a mistake to simplyequate longevity (长寿) with issues of old age. Longer lives have implications for all of life, not just the end of it.C) Our view is that if many people are living for longer, and are healthier for longer, then this will result in aninevitable redesign of work and life. When people live longer, they are not only older for longer, but also youngerfor longer. There is some truth in the saying that “70 is the new 60” or “40 the new 30.” If you age more slowlyover a longer time period, then you are in some sense younger for longer.D) But the changes go further than that. Take, for instance, the age at which people make commitments such asbuying a house, getting married, having children, or starting a career. These are all fundamental commitments thatare now occurring later in life. In 1962, 50% of Americans were married by age 21. By 2014, that milestone(里程碑)had shifted to age 29.E) While there are numerous factors behind these shifts, one factor is surely a growing realization for the young that they are going to live longer. Options are more valuable the longer they can be held. So if you believe you will live longer, then options become more valuable, and early commitment becomes less attractive. The result is that the commitments that previously characterized the beginning of adulthood are now being delayed, and new patterns of behavior and a new stage of life are emerging for those in their twentiesF) Longevity also pushes back the age of retirement, and not only for financial reasons. Yes, unless people are prepared to save a lot more, our calculations suggest that if you are now in your mid-40s, then you are likely to work until your early 70s; and if you are in your early 20s, there is a real chance you will need to work until your late 70s or possibly even into your 80s. But even if people are able to economically support a retirement at 65, over thirty years of potential inactivity is harmful to cognitive(认知的) and emotional vitality. Many people may simply not want to do it.G) And yet that does not mean that simply extending our careers is appealing. Just lengthening that second stage of full-time work may secure the financial assets needed for a 100-year life, but such persistent work will inevitably exhaust precious intangible assets such as productive skills, vitality, happiness, and friendship.H) The same is true for education. It is impossible that a single shot of education, administered in childhood and early adulthood, will be able to support a sustained, 60-year career. If you factor in the projected rates of technological change, either your skills will become unnecessary, or your industry outdated. That means that everyone will, at some point in their life, have to make a number of major reinvestments in their skills.I) It seems likely, then, that the traditional three-stage life will evolve into multiple stages containing two, three, or oven more different careers. Each of these stages could potentially be different. In one the focus could be on building financial success and personal achievement, in another on creating a better work/life balance, still another on exploring and understanding options more fully, or becoming an independent producer, yet another on making a social contribution. These stages will span sectors, take people to different cities, and provide a foundation for building a wide variety of skills.J) Transitions between stages could be marked with sabbaticals (休假) as people find time rest and recharge their health, re-invest in their relationships, or improve their skills. At times, these breaks and transitions will be self-determined, at others they will be forced as existing roles, firms, or industries cease to exist.K) A multi-stage life will have profound changes not just in how you manage your career, but also in your approach to life. An increasingly important skill will be your ability to deal with change and even welcome it. A three-stage life has few transitions, while a multi-stage life has many. That is why being self-aware, investing in broader networks of friends, and being open to new ideas will become even more crucial skills.L) These multi-stage lives will create extraordinary variety across groups of people simply because there are so many ways of sequencing the stages. More stages mean more possible sequences.M)With this variety will come the end of the close association of age and stage. I n a three-stage life, people leave university at the same time and the same age, they tend to start their careers and family at the same age, they proceed through middle management all roughly the same time, and then move into retirement within a few years of each other. In a multi-stage life, you could be an undergraduate at 20, 40, or 60; a manager at 30, 50, or 70; and become an independent producer at any age.N)Current life structures, career paths, educational choices, and social norms are out of tune with the emerging reality of longer lifespans. The three-stage life of full-time education, followed by continuous work, and then complete retirement may have worked for our parents or even grandparents, but it is not relevant today. We believe that to focus on longevity as primarily an issue of aging is to miss its full implications. Longevity is not necessarily about being older for longer. It is about living longer, being older later, and being younger longer.36. An extended lifespan in the future will allow people to have more careers than now.37. Just extending one’s career may have both positive and negative effects.38. Nowadays, many Americans have on average delayed their marriage by some eight years.39. Because of their longer lifespan, young people today no longer follow the pattern of life of their parents or grandparents.40. Many more people will be expected to live over 100 by the mid-21st century.41. A longer life will cause radical changes in people’s approach to life.42. Fast technological change makes it necessary for one to constantly upgrade their skills.43. Many people may not want to retire early because it would do harm to their mental and emotional well-being.44. The close link between age and stage may cease to exist in a multi-stage life.45. People living a longer and healthier life will have to rearrange their work and life.
