At any given time during fall or winter one can (8) one’s TV set and see the top athletic programs — from schools like Michigan, UCLA, Duke and Stanford — (9) in front of packed houses and national TV audiences.The athletes themselves are (10) and provided with scholarships. College coaches identify (11) teenagers and then go into high schools to (12) the country’s best players to attend their universities. There are strict rules about (13) coaches can recruit — no recruiting calls after 9 p. m., only one official visit to a campus — but they are often bent and sometimes (14) . Top college football programs (15) scholarships to 20 or 30 players each year, and those student-athletes, when they arrive (16) campus, receive free housing, tuition, meals, books, etc.In return, the players (17) the program in their sport. Football players at top colleges (18) two hours a day, four days a week from January to April. In summer, it’s back to strength and agility training four days a week until mid-August, when camp (19) and preparation for the opening of the September-to-December season begins (20) . During the season, practices last two or three hours a day from Tuesday to Friday. Saturday is game day. Mondays are an officially mandated day of rest. Read the following text.

Psychologically there are two dangers to be guarded against in old age. One of these is undue absorption in the past. It does not do to live in memories, in regrets for the old days, or in sadness about friends who are dead. One’’s thoughts must be directed to the future, and to things about which there is something to be done. This is not always easy; one’’s own past is a gradually increasing weight. It is easy to think to oneself that one’’s emotions used to be more active than they are, and one’’s mind more keen. If this is true it should be forgotten, and if it is forgotten it will probably not be true. The other thing to be avoided is clinging tightly to youth in the hope of sucking vigor from its vitality. When your children are grown up they want to live their own lives, and if you continue to be as interested in them as you were when they were young, you are likely to become a burden to them. I do not mean that one should be without interest in them, but one’’s interest should be thoughtful and, if possible, kindly but not unduly emotional. Animals become indifferent to their young as soon as their young can look after themselves, but human beings, owing to the length of early childhood, find this difficult. I think that a successful old age is easiest for those who have strong impersonal interest involving appropriate activities. It is in this sphere mat long experience is really fruitful, and it is in this sphere that the wisdom born of experience can be exercised without being oppressive. It is no use telling grown-up children not to make mistakes, both because they will not believe you, and because mistakes are an essential part of education. But if you are one of those who are incapable of impersonal interest, you may find that your life will be empty unless you concern yourself with your children and grandchildren. In that case you must realize that while you can still render them material services, such as making them an allowance or knitting them sweaters, you must not expect that they will enjoy your company. The second paragraph of the passage suggests________.

Farm-raised pigs are dirty, smelly animals that get no respect. They’re also an environmental hazard. Their manure contains phosphorus, which, when it rains, runs off into lakes and estuaries, depleting oxygen, killing fish, stimulating algae overgrowth and emitting greenhouse gases.41. ______. Pigs provide more dietary protein, more cheaply, to more people than any other animal. Northern Europe still maintains the highest pig-to-human ratio in the world (2-1 in Den- mark), but East Asia is catching up. During the 1990s, pork production doubled in Vietnam and grew by 70 percent in China— along densely populated coastlines, pig density exceeds 100 animals per square kilometer. The resulting pollution is “threatening fragile coastal marine habitats including mangroves, coral reefs and sea grasses,” according to a report released in February by the Food and Agriculture Organization of the United Nations.As it turns out, there is a solution to the pig problem, but it requires a change of mind-set among environmentalists and the public. 42. ______.The Enviropig is one of many new technologies that are putting environmentalists and organic-food proponents in a quandary: should they remain categorically opposed to genetically modified (GM) foods even at the expense of the environment 43. ______. The most significant GM applications will be ones that help alleviate the problem of agriculture, which accounts for 38 percent of the world’s landmass and is crowding out natural ecosystems and species habitats. GM crops that can be produced more efficiently would allow us to return land to nature.44. ______. U.S. Department of Agriculture scientist Eliot Herman has already created a less-allergenic soybean — an important crop for baby foods. Through genetic surgery, Herman turned off the soy gene responsible for 65 percent of allergic reactions. Not only was the modified soy less allergenic in tests but, as Herman explained, “the yield looks perfectly normal, plants develop and grow at a normal rate and they seem to have the same kinds of protein, oil and other good stuff in them.” Other scientists have reported promising results in shutting off allergy-causing genes in peanuts and shrimp. Should these advances be turned into products, organic soy or peanut products will be certifiably more dangerous to human health than comparable nonorganic products.45. ______. In this climate, much of the needed research isn’t being pursued. Chances are, farmers will continue to grow their polluting organic pork, their allergenic organic soy and their neurotoxin-sprayed organic apples. Worse still, they will make sure that no one else gets a choice in the matter of improving the conditions of life on earth — unless, that is, others rise up and demand an alternative.[A] Two Canadian scientists have created a pig whose manure doesn’t contain very much phosphorus at all. If this variety of pig were adopted widely, it could greatly reduce a major source of pollution. But the Enviropig, as they call it, is the product of genetic modification — which is anathema to many Westerners.[B] In fact, although all commonly used pesticides dissipate so quickly that they pose a miniscule health risk to consumers, allergic food reactions to natural products kill hundreds of children each year. Genetically modified foods could greatly reduce this risk.[C] Canadian biologists Cecil Forsberg and John Phillips, for instance, have constructed a novel DNA molecule that, when planted in a pig embryo, imbues the Enviropig with the ability to secrete a phosphorus extracting enzyme in its saliva. The results so far are dramatic — the new pigs can extract all the phosphorus they need from grain alone, without the phosphorus supplements that farmers now use. This reduces the phosphorus content of their manure by up to 75 percent.[D] Doing away with the pig is not an option.[E] Pigs can also be modified to digest grasses and hay (as cows and sheep do), reducing the energy-intensive use of corn as pig feed. Elsewhere, trees grown for paper could be made amenable to much more efficient processing, reducing both energy usage and toxic chemical bleach in effluents from paper mills.[F] Of course, stringent testing is needed to show that a genetic modification works and that the product is not harmful to humans. Scientists can do both of these things with techniques that allow them to examine and compare the structure and activity of every one of an animal’s genes.[G] Unfortunately, this won’t happen any time soon. Because no society has ever banned allergenic foods, conventional farmers have no incentive to plant reduced-allergy seeds. And many members of the public have been led to believe that all genetic modifications create health risks. 41
