听力原文： Back in those primitive times it was unnecessary to have a special form. of exchange value for everything, like a price. In thee times the only things that were really valuable were the skills to sat vive. But as society became more complex, people depend more on others who were living far away; then it became important for people to develop some method for exchanging value without having to ex change the actual goods.
This need to develop a method for exchanging value was what led to the use of money. Money was a means of exchanging value without having to actually exchange the specific things you wanted. Before the use of money, people had to trade things with each other, and it was usually very difficult to decide what everything was worth in relation to each other. If you had three animals skins and your friend had two pots of dried betas, how did you know how many skins were equivalent to a pet of beans if they didn't have a price？ With the introduction of money, all things could begin to hate a common value that everybody could know about. This led to a standardized set of values among people. As the power of money increased, values that were different from the majority were no longer recognized. The value of something in terms of money became the ultimate value. In order for money to function, the whole society has to agree on the same values.

听力原文： Doctors in Chicago said on Monday they reached their conclusions on the fat question after examining 815 people aged 65 and older who did not have Alzheimer's at the start of a nearly four-year study. Those in the study were asked to recall their dietary habits during a more than two-year period before the study began. At the end of the study the researchers found that 131 people had developed Alzheimer's, the debilitating disease that leads to memory loss and eventual physical incapacity. People who consumed the most saturated fat — the kind of fat that comes from meat, poultry, dairy products and palm or coconut oils — had 2.3 times the risk of developing Alzheimer's compared with those who consumed the lowest amount of saturated fats, the researchers said.

So, how old is old？ The answer is one you' ve heard many times, from all sorts of people. "You are as old (or young) as you feel." The calendar simply tells you how many years you have lived. Your body tells you how well you' ve lived.
"Youth", wrote an unknown author, "is not a time of life--it is a state of mind. Nobody grows old by living a number of years; people grow old by deserting (抛弃) their ideals."
Old is a point of view. Alice Brophy, when she was with the New York City Commission for the Aging, said, "It annoys me when people say, 'Gee, you look young for your age. ' What does that mean？ Is there some model that you' re supposed to look a certain way at 65 and 75 and 85？ You know, you can die old at 30 and live young at 80."
It is often believed that most older people are in poor health. But the fact is that there are neither biological nor physiological (生理学的) reasons to connect poor health with growing older. Older people are more likely to be affected with illness and physical disabilities than you are, but old age itself is not a disease. It's possible to remain physically fit throughout your life.
Which of the following statements is NOT true according to the passage？
A．The concept of "old" is differently defined in different times.
B．Nobody can remain physically healthy throughout the life.
C．The progress in medical knowledge has contributed a lot lo longer lives of us.
D．Older people may get ill and physically disabled more easily than younger ones.
