A．The great impact and progress in genetic engineering B．Worries about privacy protection C．Worries about medical use of genetic engineering D．Genetic knowledge helps to predict diseases E．Genetic knowledge may not be properly used AB．The application of genetic engineering in the medical fields |
1.__________
Current research into the human gene system is helping us understand why people have predispositions（易患某病倾向）to certain diseases．Knowing our genetic makeup can help us to judge whether or not we may be stricken by particular illness, such as cancer．Even before birth, we are able to do genetic screenings to determine what a child's genetic disorder will be．Scientists have already isolated and identified the genes responsible for the more than 4,000 genetic diseases that affect human beings．
2.__________
The implications of this knowledge are astonishing. In addition to predicting genetic predisposition towards diseases, gene therapies may provide new treatments or cures for serious diseases．Millions of people already use genetically engineered drugs to treat heart disease, cancer, AIDS, and strokes （中风）. But with the research that is now being conducted, we may find cures to many more diseases．In the near future, genetic experimentation will also allow parents to select the traits of their children. Genetic traits that determine height, weight, eye and hair color will be able to be controlled, and many parents are excited about this potential.
3.__________
Many people, however, are unwilling to accept the possibilities genetic research allowsFor example, one reason some women do not use the largest genetic testing for breast cancer is because they are afraid they will be discriminated against．Another problem is that many people do not want to discover their weakness．What if they learn that they have a disease for which there are no medical cures? How will such knowledge affect their lives? Do people really want to know what they will die of?
4.__________
Many people believe that history has not always shown human decision-making to be bright when it comes to ethical（道德的）choices. Jeremy Rifkin is probably the most well known opponent of genetic engineering. He believes that humans are not responsible enough to experiment with genes and should not “play God” He asks, “Just because it can be done, does that mean it should be done?” He points out that our society will eventually look and act the same if parents select the traits of their children, and he questions the desirability of such a society．
5.．__________
One of the fears expressed about genetic experimentation involves privacy. Already blood sample taken from patients in hospitals have been used for genetic research without the patients’ permission. Most people would agree that one’s health and genetic makeup are private concerns. But if insurance companies gain access to this information, it could have a large impact on insurance coverage or costs; if employers gain access to the information, it could have a large impact on hiring or promotion decisions. The possibilities for discrimination are obvious．
When I was seven, my parents gave me a doll, a doll’s house and a book. The Arabian Nights, came wrapped in red paper. I was just ready to read when my mother walked into my room．
“Isn’t your doll just beautiful?” my mother asked. I looked at the doll, with fair hair in a pink dress----I’ll have to call her “she” because I never gave her a name. I folded my lips and raised my eyebrows, not really knowing how to let my mother down easily.
“This doll is different.” My mother explained, trying to talk me into playing with it.
Thinking the doll needed love, I hugged her tightly for a long time. Useless, I said to myself. Finally, I decided to play with the doll’s house. But since rearranging the tiny furniture seemed to be the only active possible, I lost interest. I caught sight again of the third of my gifts The Arabian Nights, and I began to read it. From that moment, the book was my constant companion.
Every day I climbed our garden tree, nestled among its branches, I read the stories in The Arabian Nights to my heart’s content. My mother became concerned as she noticed I wasn’t playing with either the doll or the little house. She insisted that I take the doll up the tree with me.
Trying to read on a branch 15 feet off the ground while holding on to the silly doll was not easy. After nearly falling off twice, I tied one end of a long vine around the doll’s neck and the opposite one around the branch, letting the doll hang in mid air while I read. I always looked out for my mother, though. I sensed that my playing with the doll was of great importance to her. So every time I heard her coming, I lifted the doll up and hugged her. The smile in my mother’s eyes told me my plan worked.
The inevitable(不可避免的) happened one afternoon. Totally absorbed in the reading, I didn’t hear my mother calling me. When I looked down, I saw my mother staring at the hanging doll. Fearing the worst of scolding, I climbed down in a flash, reaching the ground just as my mother was untying the doll. To my surprise, she didn’t scold. She kept on staring at the doll．
The next day, my father came home early and suggested he and I play with the doll’s house. Soon I was bored, but my father seemed to be having so much fun, I didn’t have the heart to tell him. Quietly I slipped out, picking up my book on my way to the yard. So absorbed was he in arranging and rearranging the tiny furniture that he didn’t notice my quick exit.
Almost 20 years passed before I found out why the hanging-doll incident had been so significant for my parents. By then I was a parent myself. After recalling the incident, my mother said all those years she had been afraid whether I would turn out to be a most loving and understanding mother to my son．
My mother often thanks God aloud for making me a good parent, pointing out that with education I might have been a rich dentist instead of a poor poet. I look back on that same childhood incident, recalling my third gift, the book in red-paper, and I take advantage of the experiences that have made me who and what I am. Sometimes I pause to wonder at life’s wonderful ironies （讽刺）.

A. Because the gift was given by her parents.
B. Because the girl didn’t care much for the doll.

A. hoped to shape their children’s future
B. were unconcerned about their behavior
C. ruined their children’s dreams completely
D. might withdraw their love at any moment
3. What can we infer from the last paragraph?
A. The mother is now satisfied with her daughter’s career.
B. The daughter now regrets what she did when she was a girl.
C. The mother thinks the daughter’s achievements are unsatisfactory.

Many people have described television as a passive activity that is harmful to children’s education. However, there are good and bad ways to watch television. Parents who are interested in exploiting television as a learning tool can actually turn time in front of TV into an educational chance.
Probably the most familiar educational way to use television is to simply watch educational programs. In particular, this means selecting channels and programs specially designed for educational purposes. Along with traditional educational shows for children on public broadcasting channels, cable television (有线电视) now offers kids and adults a wide variety of educational programs, with everything from nature shows to historical events in different countries.
Captioning(字幕），such as "closed captioning" for hearing disabled viewers provides another way for parents to exploit the educational possibilities of television．One study showed that children who watched captioned TV got great improvement in their vocabulary and oral reading ability. In addition, parents can make any show a learning class by watching television together with children. By actively joining children in the programs that they are watching, parents can help with the development of such skills as predicting（预见）and summarizing. In order to develop predicting skills, parents and children could first refer to a program’s description in a viewing guide．After reading the program description and guessing what might happen in the program, parents and children could watch together to see which predictions were correct. And to practice summarizing, after watching a program, parents can turn off the TV and ask what the story was about. This kind of activity helps children develop thinking skills such as arranging events in an order and memorizing information．
Although there will still be plenty of times when children watch TV simply for passive enjoyment, parents can help make at least part of their children’s viewing time a more productive activity．Used intelligently by exploiting the learning chances available through various programs, television can play an instructive role in children’s education.
