单选题There is one thing that everyone wants more than anything else. Some people try to get it by making money. They think that when they have enough money to buy such things as houses, farms, and cars, they will have the one thing that everyone wants. Other people believe that if they know enough they will find this thing. They study all their lives in search of it. Still others think that if they have power, they will find this thing. They keep telling themselves: when I am a boss, I will no longer have to search for this thing. What is it that everyone wants more than anything else? What is it that all of us keep working and striving for each day? It is happiness. Happiness is a strange thing. It does not mean the same to all men. What will make one man happy may not make another man happy. Some men say that happiness comes from helping others; other men say that happiness comes from making life more pleasant for everyone. What do you mean when you say "That makes me happy"? Read what different people have said about happiness. Perhaps you will learn something that will bring you peace of mind, comfort, money or it may bring you what you search for — happiness.

单选题The first line reads; "She sits on the bed with a helpless expression. What is your name? Au-guste. Last name? Auguste. What is your husband" s name? Auguste, I think. " The 32 pages of medical records that follow are the oldest medical description of Alzheimer" s disease. Psychiatrist Konrad Maurer and his colleagues at Johann Wolfgan Goethe University in Frankfurt found the file in their hospital" s archive, where it had been missing for nearly 90 years, and published exerpts from it last May in The Lancet. The notes, in a cramped, archaic German script, were written by Alois Alzheimer—the physician who first described the disease. His patient, Auguste D. , was a 51-year-old woman who had suffered fits of paranoid jealousy and memory lapses so disturbing that her family finally brought her to a local hospital known as the Castle of the Insane. Over the next four years Aizheimer tracked her condition. Upon her death he examined her brain tissue and found the distinctive lesion that are now hallmark of the disease. Today Alzheimer" s afflicts some 4 million Americans. Although it still cannot be cured, or e-ven treated very well, several recent studies hint that some treatments—from estrogen to vitamin E to anti-inflammatory drugs—can reduce either the risk of developing the disorder or its symptoms. And more is being learned about its distinctive pathology. This past year, for instance, researchers discovered a new kind of lesion in Alzheimer" s patients. A genetic study also pinpointed a mutation that is present in some 60 percent of them—a mutation in the DNA of mitochondria, the energy— producing organelles of the cells. But nearly a century ago, it was Alois Alzheimer who first described the disease an in so doing became one of the first physicians to offer a biological basis fro a psychiatric condition. Finding the file, Maurer says, "is like holding history in your hands. "

单选题Too many vulnerable child-free adults are being ruthlessly (无情的) manipulated into parenthood by their parents, who think that happiness among older people depends on having a grand-child to spoil. We need an organization to help beat down the persistent campaigns of grandchildless parents. It"s time to establish Planned Grandparenthood, which would have many global and local benefits. Part of its mission would be to promote the risks and realities associated with being a grandparent. The staff would include depressed grandparents who would explain how grandkids break lamps, bite, scream and kick. Others would detail how an hour of babysitting often turns into a crying marathon. More grandparents would testify that they had to pay for their grandchild"s expensive college education. Planned grandparenthood"s carefully written literature would detail all the joys of grand-child-free life: a calm living room, extra money for luxuries during the golden years, etc. Potential grandparents would be reminded that, without grandchildren around, it"s possible to have a conversation with your kids, who incidentally would have more time for their own parents. Meanwhile, most children are vulnerable to the enormous influence exerted by grand-childless parents aiming to persuade their kids to produce children. They will take a call from a persistent parent, even if they"re loaded with works. In addition, some parents make handsome money offers payable upon the grandchild"s birth. Sometimes these gifts not only cover expenses associated with the infant"s birth, but extras, too, like a vacation. In any case, cash gifts can weaken the resolve of even the noblest person. At Planned Grandparenthood, children targeted by their parents to reproduce could obtain non-biased information about the insanity of having their own kids. The catastrophic psychological and economic costs of childbearing would be emphasized. The symptoms of morning sickness would be listed and horrors of childbirth pictured. A monthly newsletter would contain stories about overwhelmed parents and offer guidance on how childless adults can respond to the different lobbying tactics that would-be grandparents employ. When I think about all the problems of our overpopulated world and look at our boy grabbing at the lamp by the sofa, I wish I could have turned to Planned Grandparenthood when my parents were putting the grandchild squeeze on me. If I could have, I might not be in this parenthood predicament (窘境). But here"s the crazy irony, I don"t want my child-free life back. Dylan"s too much fun. (406 words)
