If a way could be found to "test" routinely the genes of prospective married couples-much as the couples now take Wassermann tests to detect syphilis(梅毒 )-the toll(伤亡人数) might be reduced drastically. This is the goal of genetic counseling. And while it is still far off--testing is expensive and elaborate--genetic counseling centers in hospitals and clinics across the United States are already helping parents. At a symposium sponsored by the National Foundation March of Dimes in New York City, it was announced that between 1955 and 1969 the number of centers bad grown from 20 to 114. Such centers help the parents of a defective child in their couples with family histories of genetic diseases even before marriage. The genes that help determine a person's individual characteristics-from the colors of his eyes to the score he makes on an IQ test-are located on chromosomes within the cells of his body. Half of a person's chromosomes come from his father, half from his mother. Many diseases are the result of a single defective gene on one of the chromosomes. Achondroplastic(软骨营养障碍性) dwarfism, for example, is caused by a dominant gene and any child who inherits it will have the disease. A genetic counselor confronted by a parent with such a disease could warn that half of his children risk the disease. More often, genetic disease are caused by recessive genes(隐性基因). The most common is cystic fibrosis, a disorder that affects at least one in every 1,500 babies and causes their lungs and other body organs to become congested with mucus(粘液) .A child who inherits only one of these recessive genes will not have the disease, but will be a carrier. If both parents are carriers, one in four of their children will have cystic fibrosis(囊性纤维 变性), two will be carriers, and one will be normal. 1. The major point stated in the first paragraph is that____ [A] all physical and mental abnormalities are caused by defective genes [B] genetic counseling could decrease the number of people born with genetic defects [C] genetic counseling is expensive and not available in most hospitals in the U.S. [D] possible fatal abnormalities in body chemistry often resulted from defective genes or chromosomes 【参考答案】：B 【学生得分】：0.0 ------------------------------------转---------------------------------------------------------订--------------------------------------------------------------线------------------------------------------------- 院：动物科学技术学院专业：水产养殖学号：_______姓名：_______ 教学班号：1 -----------------------------------------密-----------------------------------------------------封------------------------------------------------线-------------------------------------------------------------√ 2.

If they ever just sat down and had a nice, honest talk about their feelings and the situation they're in, the problems would instantly resolve themselves and the movie would be over. That, of course, is why they don't do it. But then again, they're guaranteed a happy ending in two hours, no matter how badly they mess up. In real life, things aren't so easy. Talk about the things that bother you while they're still small. Discuss molehills so that you don't have mountains to argue about later on. Remember that if the two of you can really talk to each other, and listen to each other, there is no problem you can't solve.One day, Gary and I, out of the blue, got irritated and quarreled with each other rather pointlessly. I thought he was unfair to shout at me for no reason, and he felt the same way. So there we were, each feeling wounded and resentful, all swelled up with righteous indignation over how we'd been treated. About five minutes passed in total silence, one of us said, "I'm sorry I snapped at you. I think I'm annoyed about something else and just took it out on you." The other immediately apologized as well, and we sat down and talked for about an hour.It turned out that we were both stressed about different things, he about work and me about a friend who had hurt my feelings, and we were edgy with each other as a result. Had we not discussed it right then and there, we would have gone away harboring hurt feelings and resentment. Someday the cumulative total of all that hurt and resentment would have blown up into a huge battle that our relationship might not have survived. But because we discussed it and realized that what was really wrong had nothing to do with our relationship, it became a bonding experience that brought us closer. After we settled that disagreement, we went on to discuss the reasons we were stressed out. He was able to shed some light on my situation with my friend, and his insight helped me resolve the problem. I was able to bring a fresh perspective to his work dilemma and help him find the best way to handle it. So in one conversation, not only did we diffuse a potential area of trouble in our relationship, but we shared a deeply bonding experience and each helped the other solve a personal problem. That was an hour well spent, in so many ways, and serves as a prime example of what I mean when I say, handle the molehills and there won' t ever be any mountains. √ 6.
