单选题{{B}}第二篇{{/B}} Speech therapists divide their cases into common and complex. An example of a complex case is a person suffering from aphasia. This is the loss of the ability to under- stand and/or use speech. There are many causes of aphasia, including partial brain dam- age that leaves the individual with the physical ability to speak. If the individual is able to speak but does not, the therapist must determine the cause of such conduct. Often, speech therapists determine that problems are emotional and refer the individuals with such problems to psychologists or psychiatrists trained to help them. While a speech therapist is not trained to help persons with severe emotional disorders, the therapist does receive extensive training in such areas as anatomy(as it relates to speech, concentrating on the diaphragm, tongue, and palate), physics(particularly relating to sound), and language and communications. Some therapists take classes in elementary psychology as well. The speech therapist must be able to diagnose the type and severity of the speech defect, then prescribe a series of treatments. While some people with severe handicaps receive individual instruction, most patients are comfortable receiving group therapy with others who have the same problem. If a patient is found to have a physical handicap that is impeding his progress, he is sent to a doctor with whom the therapist works closely. Many therapists have a high success rate with their patients. No scientific studies have yet shown whether the intervention of the therapist was in fact the sole cause of the improvement of the patients, or whether time and maturity helped as well. A recent study has shown that persons who have not received speech therapy have often been "cured' of their problems merely by being around others without the problem. However, that same study showed that those few persons who were not treated by therapists had extremely low self-esteem and considered themselves " different" and "retarded". The therapists often are able to make the patients see that while they are different, the difference is not of their own making, that they have not done something wrong. Therapists try to reach children when they are very young, before they have had an opportunity to be teased by other children or made to feel they are "stupid". Therapists often work with whole families, encouraging the parents and siblings to listen to the patients, taking the time to help them feel they are an important part of the family, not just brushing them off because the effort of interpreting their speech is too great or time-consuming.

单选题Breakfast Studies show that children who eat breakfast do better in school. It doesn"t take much further thought to believe that adults will feel better and perform better at work as well. Whether you work at home, on the farm, at the office, at school, or on the road, it is not a good idea to skip (故意略去) breakfast. If we don"t eat breakfast, we are likely to become tired when our brains and bodies run low on fuel. By mid-morning, a lot of us grab a cup of coffee, or wolf down a sugary candy bar to wake up again. This might work for a few minutes, but by lunchtime we are hungry, bad-tempered, and perhaps our mood might make us a little more likely to make unhealthy choices at lunch. Eating a good breakfast sets the tone for the rest of the day. People who eat breakfast are generally more likely to maintain a healthy weight. Many people believe that they will lose weight if they skip meals, but that isn"t a good idea. The body expects to be refueled a few times a day, so start with a healthy breakfast. A healthy breakfast should contain some protein (蛋白质) and some fiber (纤维). Protein can come from meat, eggs, beans, or soy (大豆). Fiber can be found in whole cereals (谷物), grains or in fruits. A good example of a healthy breakfast might be something simple like a hard boiled egg, an orange, and a bowl of whole grain cereal with soy milk.

单选题Most Adults in U.S. Have Low Risk of Heart Disease More than 80 percent of U.S. adults have a less than 10-percent risk of developing heart disease in the next 10 years, according to a report in the Journal of the American College of Cardiology. Just 3 percent have a risk that exceeds 20 percent. "I hope that these numbers will give physicians, researchers, health policy analysts, and others a better idea of how coronary heart disease is distributed in the U.S. population," lead author Dr. Earl S. Ford, from the Centers for Disease Control and Prevention in Atlanta, said in a statement. The findings are based on analysis of data from 13,769 subjects, between 20 and 79 years of age, who participated in the Third National Health and Nutrition Examination Survey from 1988 to 1994. Overall, 82 percent of adults had a risk of less than 10 percent, 15 percent had a risk that fell between 10 to 20 percent, and 3 percent had a risk above 20 percent. The proportion of subjects in the highest risk group increased with advancing age, and men were more likely than women to be in this group. By contrast, race or ethnicity had little effect on risk distributions. Although the report suggests that most adults have a low 10-year risk of heart disease, a large proportion have a high or immediate risk, Dr. Daniel S. Berman, from Cedars-Sinai Medical Center in Los Angeles, and Dr. Nathan D. Wong, from the University of California at Irvine, note in a related editorial. Aggressive treatment measures and public health strategies are needed to shift the overall population risk downward, they add.

单选题After-birth Depression Blamed for Woman's Suicide A. new mother apparently suffering from postpartum mental illness fell to her death from a narrow 12th-floor ledge of a Chicago hotel, eluding the lunging grasp of firemen called to help. The Chicago Tribune reported Tuesday that the mother of a 3-month-old daughter, Melanie Stokes, 41, was said to be suffering from a severe form of after-birth depression called postpartum psychosis, an extremely rare biological response to rapidly changing hormonal levels that can result in hallucinations, delusions, severe insomnia and a drastic departure from reality. "That was a monster in my daughter's brain, " said Stokes' mother, Carol Blocker. "The medicine took no effect at all, while her grief was so strong that nothing could make up for it. I'm just glad she didn't take her daughter with her. " Virtually all new mothers get postpartum blues, also called the "baby blues". which are brief episodes of irritability, moodiness and weepiness. About 20 per cent of birthing women experience postpartum depression, which can be triggered by hormonal changes, sleeplessness and the pressures of being a new mother. It is often temporary and highly treatable. But The Tribune said what scientists suspect Stokes was battling, postpartum psychosis, is even more extreme and is considered a psychiatric emergency. During postpartum psychosis — a very real disorder that affects less than I percent of women, according to the National Institute of Mental Health — a mother might hear voices, have visions, feel extremely agitated and be at risk of harming the child or herself. Often the consequences are tragic. In 1987, Sheryl Masip of California told a judge that postpartum psychosis made her drive a Volvo over her 6-week-old son. Latrena Pixley of Washington, D. C. , said the disorder was why she smothered her 6-week-old daughter in 1992. And last year, Judy Kirby, a 31-year-old Indianapolis mother allegedly suffering from postpartum psychosis, sped into oncoming traffic and plowed into a minivan, killing seven youngsters. including three of her own.

单选题 IQ-gene In the angry debate over how much of IQ comes from the genes that children inherit from parents and how much comes from experiences, one little fact gets overlooked: no one has identified any genes (other than those that cause retardation) that affect intelligence. So researchers led by Robert Plomin of London's Institute of Psychiatry decided to look for some. They figured that if you want to find a "smart gene", you should look in smart kids. They therefore examined the DNA of students like those who are so bright that they take college entrance exams four years early—and still score at Princeton-caliber levels. The scientists found what they sought. "We have," says Plomin, "the first specific gene ever associated with general intelligence." Plomin's colleagues drew blood from two groups of 51 children each, all 6 to 15 years old and living in six counties around Cleveland. In one group, the average IQ is 103. All the children are white. Isolating the blood cells, the researchers then examined each child's chromosome 6. Of the 37 landmarks on chromosome 6 that the researchers looked for, one jumped out: a form of gene called IGF2R occurred in twice as many children in the high-IQ group as in the average group—32 percent versus 16 percent. The study, in the May issue of the journal Psychological Science, concludes that it is this form of the IGF2R gene that contributes to intelligence. Some geneticists see major problems with the IQ-gene study. One is the possibility that Plomin's group fell for "chopsticks fallacy". Geneticists might think they've found a gene for chopsticks flexibility, but all they've really found is a gene more common in Asians than, say, Africans. Similarly, Plomin's IQ gene might simply be one that is more common in groups that emphasize academic achievement. "What is the gene that they've found reflects ethnicity?" asks geneticist Andrew Feinberg of Johns Hopkins University. "That alone might explain the link to intelligence, since IQ tests are known for being culturally sensitive and affected by a child's environment." And Neil Risch of Standford University points out that if you look for 37 genes on a chromosome, as the researchers did, and find that one is more common in smarter kids, that might reflect pure chance rather than a causal link between the gene and intelligence. Warns Feinberg: "I would take these findings with a whole box of salt."
