Read the following passage and choose the best answer for each of the questions.
Aging is the process of growing old. It occurs eventually in every living thing provided, of course, that an illness or accident does not kill it prematurely. The most familiar outward signs of aging may be seen in old people, such as the graying of the hair and the wrinkling of the skin. Signs of aging in a pet dog or cat include lass of playfulness and energy, a decline in hearing and eyesight, or even a slight graying of the coat. Plants age too, but the signs are much harder to detect.
Most body parts grow bigger and stronger, and function more efficiently during childhood. They reach their peak at the time of maturity, or early adulthood. After that, they begin to decline. Bones, for example, gradually become lighter and more brittle. In the aged, the joints between the bones also become rigid and more inflexible. This can make moving very painful.
All the major organs of the body show signs of aging. The brain , for example, works less efficiently, and even gets smaller in size. Thinking processes of all sorts are slowed down. Old people often have trouble in remembering recent events.
One of the most serious changes of old age occurs in the arteries, the blood vessels that lead from the heart. They become thickened and constricted, allowing less blood to flow the rest of body. This condition accounts, directly or indirectly, for many of the diseases of the aged. It may, for example, result in heart attack.
Aging is not a uniform process. Different parts of the body wear out at different rates. There are great differences among people in their rate of aging. Even the cells of the body differ in the way they age. The majority of cells are capable of reproducing themselves may times during the course of a lifetime. Nerve cells and muscle fibers can never be replace once they wear out.
Gerontologists- scientists who study the process of aging- believe this wearing out of the body is controlled by a built- in biological time clock. They are trying to discover how this clock works so that they can slow down the process. This could give man a longer life and a great number of productive years.

Read the following passage, translate and write T (for TRUE) and F (for FALSE).
Like most other hobbies, stamp colleting can be exhilarating, time-consuming and, for the uninitiated, overwhelming. Consider this - it is estimated that in the last 100 years alone, close to one billion diffrent stamps have been issued by governments all around the world. Not only that, but some of these stamps are as rare, and as expensive, as Renaissance paintings. The most famous is probably the upside-down airplane stamp, valued at almost 1 million dollars. Also the result of a printing mistake is the world's most expensive stamp, the Treskilling Yellow, so called because it was originally worth three shillings when issued in Sweden in 1855, and because it was supposed to be printed in green, this being the only known sample in yellow. This stamp was recently sold at auction for 1.7 milion pounds, making it the single most expensive item by weight in the world. Of course, amateur philatelists would do well to concentrate on a sub-section of the wonderful world that is philately, such as collecting every stamp issued by a certain government in a year, or collecting every stamp of a particular design, etc. Any other approach to this hobby is a sure fire recipe for frustration and perhaps for ruin.
1. This artical mainly tells hobbyists how to get into stamp collecting. T
2. The most famous stamp is also the most expensive.T
3. Both of the stamps mentioned have printing mistakes. F
4. The sale of the world's most expensive stamp was arranged through a private dealer. F
