In modern society there is a great deal of argument about competition . Some value it highly . believing that it is responsible for social progress and prosperity . Others say that competition is bad ; that it sets one person against another ; that it leads to unfriendly relationship between people .

I have taught many children who held the belief that their self-worth relied (依赖)on how well they performed at tennis and other skills .For them , playing well and winning are often life-and-death affairs . In their single-minded pursuit ( 追求)of success , the development of many other human qualities is sadly forgotten .

However . while some seem to be lost in the desire to succeed , others take an opposite attitude .In a culture which ualues only the winner and pays no attention to the ordinary players , they strongly blame competition . Among the most vocal are youngsters who have suffered under competitive pressures from their parents or society . Teaching these young people . I often observe in them a desire to fail . They seem to seek failure by not trying to win or achieve success . By not trying , they always have an excuse : “I may have lost . but it doesn’t matter because I really didn’t try . “What is not usually admitted by themselves is the belief that if they had really tried and lost, that would mean a lot . Such a loss would be a measure of their worth . Clearly, this belief is the same as that of the true competitors who try to prove themselves . Both are based on the mistaken belief that one’s self-respect relies on how well one performs in comparison with others . Both are afraid of not being valued . Only as this basic and often troublesome fear begins to dissolve (缓解) can we discover a new meaning in competition .

Animals can move from place to place ,but plants cannot. When an animal is under attack ,it can run away or fight back .Plants certainly cannot run away ,and they lack teeth and claws .But plants can defend themselves by using both physical and chemical means.

Some plants have their own ways to keep animals away .For example ,the leaves of the holly plant have sharp spines（刺）that discourage grass-eating animals .Holly leaves on lower branches have more spines than leaves on upper branches .This is because the lower leaves are easier for most animals to reach.

Some plants ,such as the oak tree, have thick and hard leaves that are difficult for animals to eat .Some grasses may contain a sandy material ,eating such grasses wears down the animal’s teeth .

Many plants also have chemical defenses .Some plants produce chemicals that taste bitter or cause an unpleasant reaction. Some plants may fight against an attack by increasing the production of these chemicals .When a caterpillar（毛虫）bites a tobacco leaf ,the leaf produces a chemical messenger .This messenger sends to the roots the information to produce more nicotine .The higher levels of nicotine discourage the caterpillar.

Many plants depend on both physical and chemical defenses. A certain plant in China ,for instance, has prickly （多刺的）leaves, and each prickle contains poisonous venom（毒液）A single experience with this kind of plant will teach an animal to stay away from it in the future.

68．The holly plant has more spines on the lower leaves because most animals .

A．are not tall enough B．like the lower leaves only

C．are not clever enough D．can get the lower leaves easily

The population of the United States is growing older and will continue to do so.

According to a report, 39 million Americans will be 65 or older by the yew 2010, 51 million by 2020, and 65 million by 2030.

The "graying" of the United States is mainly due to the fact that people in the U. S. living longer. As a matter of fact, the number of U.S. citizens 85 years old and older is growing six times as fast as the rest of the population. It is also largely due to the old-growing of the "baby boomers," the generation born after World War II. In 1957, over 4.3 million babies were born. More than 75 million Americans were born between 1946 and 1964, the largest generation in U.S. history. In less than twenty pears, millions of them will become elderly people.

The "graying" of the U.S. will greatly affect the nation's family and workforce. One likely development will be a gradual change in the family unit; it will move away from the nuclear family and towards a multigenerational family. The other likely development will be a change m the proportion (比例) of the nation's workforce. In 1989 there were 3.5 workers for every person 65 and older; by the year 2030, there will only be 2 workers for every person 65 and older.
