A Gay BiologistMolecular biologist Dean Hamer has blue eyes, light brown hair and a good sense of humor. He smokes cigarettes, spends long hours in an old laboratory at the US National Institute of Health, and in his free time climbs up cliffs and points his skis down steep slopes. He also happens to be openly, matter-of-factly gay. What is it that makes Hamer who he is What, for that matter, accounts for the talents and traits that make up anyone’s personality Hamer is not content merely to ask such questions: he is trying to answer them as well. A pioneer in the field of molecular psychology, Hamer is exploring the role of genes in governing the very core of our individuality. To a remarkable extent, his work on what might be called the gay, thrill-seeking and quit-smoking genes reflects how own genetic predispositions. That work, which has appeared mostly in scientific journals, has been gathered into an accessible and quite readable form in Hamer’s creative new book, Living with Our Genes. "You have about as much choice in some aspect of your personality," Hamer and co-author Peter Copeland write in the introductory chapter, "as you do in the shape of your nose or the size of your feet". Until recently, research into behavioral genetics was dominated by psychiatrists and psychologists, who based their most compelling conclusions about the importance of genes on studies of identical twins. For example, psychologist Michael Bailey of Northwestern University famously demonstrated that if one identical twin is gay, there is about a 50% likelihood that the other will be too. Seven years ago, Hamer picked up where the twin studies left off, homing in on specific strips of DNA that appear to influence everything from mood to sexual orientation. Hamer switched to behavioral genetics from basic research, after receiving his doctorate from Harvard, he spent more than a decade studying the biochemistry of a protein that cells use to metabolize heavy metals like copper and zinc. As he was about to turn 40, however, Hamer suddenly realized he had learned as much about the protein as he cared to. "Frankly, I was bored," he remembers, "and ready for something new." Homosexual behavior, in particular, seemed ripe for exploration because few scientists had dared tackle such an emotionally and politically charged subject. "I’m a gay," Hamer says with a shrug, "but that was not a major motivation. It was more of a question of intellectual curiosity—and the fact that no one else was doing this sort of research." The first paragraph describes Hamer’s ______.

A. looks, hobbies and character
B. viewpoint on homosexuality
C. unique life-style
D. scientific research work

Caring for the Old 1. The old do not have to look exclusively to the past. Relieved of some of life’s responsibilities and fortified by many years of experience and knowledge, they may have a much better idea of how to spend their time enjoyably than they did in their youth. And not all enjoyment is restricted to the mental or philosophical. Healthy physical activity remains quite possible for most of us well into our later years. 2. Old people sometimes display surprising freedom and forthrightness in the expression of their thoughts and feelings, and an ability to transmit affection. It is as though some of the rituals which constrict us in earlier life fall away. 3. But a higher percentage of people suffer from emotional distress in old age than at any other time in adult life, and the gap between need and care is often filled by dubious measures, such as heavy-handed prescription of medicine. For many years it was assumed that old people were not appropriate candidates for psychotherapy. But a few clinicians have risen to the challenge and discovered that individual and group psychotherapy is just as effective with the old as with the young. 4. It is easy to understand why an earthquake causes terror. Yet in old age there may be terror of a very private nature, a sense of disintegration sometimes stemming from inner conflicts, sometimes from a premonition of death or the fear of becoming dependent. 5. Dependency is a grim choice: insecurity and deprivation must be weighed against loss of autonomy and integrity. But if there is nothing shameful about the dependency of a baby or a young child, there should be nothing shameful about the dependencies natural with old age and diminishing physical resources. 6. The complexity and impersonality of the bureaucratic establishments, which have the means to provide help, are often threatening to old people. The younger generation today, on the other hand, will have had many decades to interact with "the system" by the time they reach old age. 7. Many of us, including healthcare providers, assume that we know what old people and dying people want, but our assumptions are often a reflections of our own thoughts and feelings based on personal interpretations of scanty bits of observation. Such assumptions are really an excuse to avoid close contact with the terminally ill. Assuming we "know" what they want, we observe ourselves from being with them, and sharing their thoughts about the end of life. 8. We sometimes assume, wrongly, that old people are too confused or senile to be aware of the nearness of death. In consequence, communication between a dying and others is subject to extraordinary omissions and distortions. "Protecting" the dying from knowledge of their condition often serves to protect us from the uncomfortable prospect of talking about dying and death. Evasions like this only lead to increasing isolation at a time when emotional honesty and understanding are most needed. A. Knowing Better How to Enjoy Life B. Freedom in Expression C. Psychotherapy Effective with Some of the Old D. Period of Greater Emotional Distress E. Dependency. a Grim Choice F. Guiltiness. Dependency We often think that we know the feeling of a dying person, ______.
