6、listening for GistLike the “Iron Age“ volunteers, Paul has also chosen to cut himself off from many aspects of modem life, not, however, as an experiment but because he feels it is a more satisfactory way to live. He is talking about his small cottage in the Welsh mountains: “And that brings me to s
7、ay what is primitive about it, namely, it is anything that has to be done, and there are obviously certain basic needs of life, is DIY as they say: Do it yourself. There is no labor to be had nowadays in such a remote part. Er, there are no neighbors for most of the year and so you are on your own e

Er, the building itself - its important to keep it clean and its stupid to try. We try to keep it tidy, and reasonably clean. It is very difficult to keep it warm, warm enough p
9、articularly in winter and that we do by an old kitchen range with coal and wood.“ Exercise Directions: Listen to the passage and find its topic sentence. The topic sentence is “The place itself is extremely primitive.“ Section Two Listening ComprehensionPart1 DialogueA Healthy LifeDr Martin Answay w
10、rites a column in a popular womens magazine on health problems. He is also an expert on heart disease. Q: Is there a secret to good health? I mean, is there some way we can achieve it which is not generally known? A: It certainly isnt a secret. However, there is a great deal of ignorance, even among
11、 supposedly educated people, about how to be reasonably healthy. Q: Well, what advice do you give, then? A: Vh . to begin with, take diet. I believe that one of the greatest dangers to health in Britain and other countries . particularly developed countries . is the kind of food we tend to prefer. Q
12、: Such as? A: Such as that great national institution, the British breakfast, for example, ham and eggs. Or the kind of lunch so many people in this country have: sausage and chips! Or all the convenience foods like hamburgers. Or even things we regard as “healthy“, such as full-fat milk. Or Cheddar
13、 cheese. The list is endless. Q: Whats wrong with those things? A: The excessive consumption of such things leads to the overproduction of cholesterol, which in turn results in heart attack . Q: Excuse me, but what exactly is cholesterol? A: Its a . wax-like substance . yellowish . and its produced
14、naturally in our livers. We all need some cholesterol for survival. Q: Well, if we need it, in what way is it bad for us? A: Too much of it is bad for us. It builds up in our arteries, causing them to get narrower, so that our blood supply has difficulty in getting through . and this, of course, can
15、 eventually end in a heart attack or stroke. The point Im trying to make here is that, even though we all need some cholesterol in order to insulate our nerves, and to produce cell membranes and hormones, the things many of us eat and even consider healthy lead to the overproduction of cholesterol.
16、And this is very dangerous. Q: How can we avoid this overproduction of cholesterol? A: By cutting down our consumption of animal fats: things like red meat, cheese, eggs, and so on. And by increasing our consumption of fresh fruit and vegetables, and also by eating more potatoes, rice, pasta and bre
17、ad. Q: Pasta? Potatoes? But . arent such things fattening? A: Nonsense. It isnt pasta, potatoes or bread that makes us fat. Its what we put on such things! Cheese, Butter, Meat! Q: So anything we like, anything thats delicious, is bad for us. Isnt that what youre saying? A: Rubbish! Im simply saying
18、 we eat too much of these things. And there are many ways of preparing delicious food without using such large quantities of animal fats. Q: Last of all, what about exercise? You recently warned against certain forms of exercise, which you said could be dangerous. A: What I said was that if people a
19、rent used to getting regular and vigorous exercise, they should begin slowly, and not try to do too much at the beginning! I also said that certain games, such as squash, can be dangerous, particularly if you arent used to playing them. A number of injuries are due to sudden, twisting movements that
20、 games like squash involve. Q: What kinds of exercise do you recommend, then? A: Gentle jogging, swimming, cycling, brisk walking . exercise that is rhythmic and gentle, and above all, sustained. That is, done for at least fifteen minutes uninterruptedly at least three times a week. We all need such
21、 exercise, and the fact is that far too few of us get enough of it, particularly if we live in large cities and regularly use cars.

26、States has traditionally been based on the so-called three-legged stool: Social Security, private pensions, and other personal saving. 3)Retirement planning takes time, and these issues need to be addressed sooner rather than later. 4)One found that in 1991 the median household headed by a 65-69-yea
27、r-old had financial assets of only $14,000, but expanding the measure to include Social Security, pensions, housing, and other wealth boosts median wealth to about $270,000. 5)Only one or two generations of Americans have had lengthy retirements, and the crucial retirement issues keep changing rapid
28、ly, making long-term predictions even harder. The Baby Boom* generation - the roughly 76 million people born between 1946 and 1964has been reshaping American society for five decades. From jamming the nations schools in the 1950s and 1960s, to crowding labor markets and housing markets in the 1970s
29、and 1980s, to affecting consumption patterns almost continuously, boomers have altered economic patterns and institutions at each stage of their lives. Now that the leading edge of the generation has turned 50, the impending collision between the boomers and the nations retirement system is naturall
30、y catching the eye of policymakers and the boomers themselves. Retirement income security in the United States has traditionally been based on the so-called three-legged stool: Social Security, private pensions, and other personal saving. Since World War II the system has served the elderly well: Th
31、e poverty rate among elderly households fell from 35 percent in 1959 to 11 percent in 1995 . Are the baby boomers making adequate preparations for retirement? In part, the answer depends on what is meant by “adequate“. One definition is to have enough resources to maintain pre-retirement living stan
32、dards in retirement. A rule of thumb* often used by financial planners is that retirees should be able to meet this goal by replacing 60-80 percent of pre-retirement income. Retired households can maintain their pre-retirement standard of living with less income because they have more leisure time,
33、fewer household members, and lower expenses. Taxes are lower because retirees escape payroll taxes and the income tax is progressive. And mortgages have, for the most part, been paid off. On the other hand, older households may face higher and more uncertain medical expenses, even though they are co
34、vered by Medicare. From a public policy perspective, assuring that retirees maintain 100 percent of pre-retirement living standards may be overly ambitious. But should policymakers aim to ensure that they maintain 90 percent of their living standards? Or that they stay out of poverty? Or use some other criterion? Retirement planning takes time, and these issues need to be addressed sooner rather than later. A second big question is how to measure how well baby boomers are preparing for retirement. Studies that focus only on
