4、erienced or knew someone who had experienced a breach in confidentiality. “Two types of breaches occurred, “ Whetten-Goldstein noted. “The first was a more obvious type of breach. One example was a nurse who told her child that her patient was HIV-positive out of concern that her child would play wi

7、nd why it is being done,“ Whetten-Goldstein said. “They also felt that providers should be punished when a breach occurs. “However, because patients are often reluctant to seek legal action which may further expose their status, they felt that the system should regulate itself, “ she added.（分数：21.00

32、A.B.C.What Is a Dream?For centuries, people have wondered about the strange things that they dream about. Some psychologists say that this nighttime activity of the mind has no special meaning. Others, however, think that dreams are an important part of our lives. In fact, many experts believe that

33、dreams can tell us about a persons mind and emotions.Before modern times, many people thought that dreams contained messages from God. It was only in the twentieth century that people started to study dreams in a scientific way.The Austrian psychologist, Sigmund Freud, was probably the first person

34、to study dreams scientifically. In his famous book, The interpretation of Dreams (1900), Freud wrote that dreams are an expressions of a persons wishes. He believed that dreams allow people to express the feelings, thoughts, and fears that they are afraid to express in real life.The Swiss psychiatri

35、st Carl Jung was once a student of Freuds. Jung, however, had a different idea about dreams. Jung believed that the purpose of a dream was to communicate a message to the dreamer. He thought people could learn more about themselves by thinking about their dreams. For example, people who dream about

36、falling may learn that they have too high an opinion of themselves. On the other hand, people who dream about being heroes may learn that they think too little of themselves.Modern-day psychologists continue to develop theories about dreams. For example, psychologist William Domhoff from the Univers

37、ity of California, Santa Cruz, believes that dreams are tightly linked to a persons daily life, thoughts, and behavior. A criminal, for example, might dream about crime.Domhoff believes that there is a connection between dreams and age. His research shows that children do not dream as much as adults

38、. According to Domhoff, dreaming is a mental skill that needs time to develop.He has also found a link between dreams and gender. His studies show that the dreams of men and women are different. For example, the people in mens dreams are often other men, and the dreams often involve fighting. This i

39、s not true of womens dreams. Domhoff found this gender difference in the dreams of people from 11 cultures around the world, including both modern and traditional ones.Can dreams help us understand ourselves? Psychologists continue to try to answer this question in different ways. However, one thing

40、 they agree on this: If you dream that something terrible is going to occur, you shouldnt panic. The dream may have meaning, but it does not mean that some terrible event will actually take place. Its important to remember that the world of dreams is not the real world.（分数：21.00）(1).Not everyone agr

43、different things.A. Right B. Wrong C. Not mentioned（分数：3.00）A.B.C.(7).Scientists agree that dreams predict the future.A. Right B. Wrong C. Not mentioned（分数：3.00）A.B.C.Red Meat Links to Higher Risk of Breast CancerExercise and keeping a healthy weight are two things that doctors say might help women

44、lower their risk of breast cancer.Mothers may reduce their risk if they breastfeed for at least four months. For older women, hormone replacement therapy can lower the risk of some other diseases. But it has been found to increase the risk of breast cancer. So women should consider their choices car

45、efully. The same may be said for diet.New findings show that younger women who eat a lot of red meat have higher rates of breast cancers called hormone-receptor positive. The growth is fed by the levels of estrogen or another hormone, progesterone, in the body.Researchers at Brigham Womens Hospital

46、in Boston, Massachusetts, reported the findings as part of a health study of nurses. The researchers followed the health of more than 90,000 women from 1991 to 2003. Those who ate the most red meat ate more than one and one-half servings a day. A serving was defined as roughly 84 grams. Those who at

47、e the least red meat ate less than three servings a week. This is what the study found about breast cancers that were hormone receptor-positive: The women who ate the most red meat were almost two times as likely to get them as the women who ate the least of it.Eunyoung Cho, the lead author of the r

48、eport, says more research is needed to know the reason for the link. But in the past, researchers have suggested that three things may play a part. One is the way meat is cooked or processed. Another is the use of growth hormones in cows. And the third is the kind of iron in red meat. The study appe

49、ars in the Archives of Internal Medicine.And now we have more to tell you about our subject resveratrol. We discussed a study in the United States that found that large amounts of this plant compound helped fat mice live longer. The mice were fed much more resveratrol than people could get from red wine, one of the foods that contains it.Now, scientists in France say resveratrol also improves muscle performance again, at least in mice. They were able to run two times as far in laboratory treadmill tests as mice normally could. The study at the Institute of Genetics
