Section C 26 Why we dream still remains one of the great mysteries. But in answer to the question of how we dream, scientific researchers have【 B1】 _ some import

16、ant answers. According to dream researcher Michael Schredl, dream consciousness and consciousness are【 B2】 _ the same. This confirms the experience people have every night that what happens in dreams, no matter how fantastic,【 B3】 _ and lacking in reason or logic, is felt to be exactly【 B4】 _ life i

17、s when a person is awake. A discovery in 1953 called “REM(rapid eye movement)sleep“ initially found that dream phases 【 B5】 _ by rapid eye movements are guided by the brain stem. This is the region of the brain which regulates a persons breathing and body warmth, but has little involvement with cons

18、ciousness. This led American sleep researcher Allan Hobson to conclude that dreams were a【 B6】 _product of various actions of the nerves. REM could be a mechanism which【 B7】 _ dream events, but one can also dream without this【 B8】 _. Dreams can be produced not from primitive, but rather from higher

19、regions of the brain those which handle things like【 B9】 _, emotions, memory and sensory experience. There is no【 B10】 _ difference in dreams, but only a difference in waking experience, which then is reflected again in the dream. 27 【 B1】 28 【 B2】 29 【 B3】 30 【 B4】 31 【 B5】 32 【 B6】 33 【 B7】 34 【 B

This years analysis focused on teens, and on a 10-point scale,【 C1】 _ranked their stress at 5.8, compared with a score of 5.1 reported by adults

21、. Even more【 C2】 _, says Norman Anderson, CEO and executive vice president of the APA, is the fact that most teens knew their stress levels werent healthy they said 3.9 was probably more【 C3】 _ but did little about it. In fact, the survey【 C4】_that 42% of teens arent doing enough to manage their str

You feel anxious a

27、nd worried. Theres plenty to do, but the work piles up because you feel listless and tired. You dont even want to do anything fun. Friends tell you to “pull yourself together,“ but you feel helpless and hopeless. You have difficulty concentrating and making decisions When you look in the mirror, you

28、 hate yourself. You are definitely in one of lifes valleys you are depressed. Everyone gets the blues once in a while. Emotional lows and highs are a normal part of life. The blues become depression when you feel so sleepy and listless that you cant function normally in everyday life. BDepression oc

29、curs at all ages, although major depressive episodes peak between the ages of 55 and 70 in men and 20 and 45 in women. About half of those who experience an episode of major depression will have another within two years. For some people, episodes of depression are separated by several years, while o

30、thers suffer groups of episodes over a short time span. Between episodes, such individuals feel well. CMajor depressive disorder affects approximately 14.8 million American adults or 6.7 percent of the U.S. population aged 18 years and older in a given year. Major depressive disorder is more common

31、in women than in men. Although treatment can help more than 80 percent of people with severe depression, most people with depression do not seek treatment. Depression can range from a mild panic to self-destructive or suicidal behavior. Its important to understand the various types of depression so

32、that you can recognize them. DReactive depression. This type of depression is a reaction to stressful events divorce, death of a loved one, a chronic illness, a personal tragedy, or even social isolation, which the elderly frequently experience. The person is unable to recover normally from the. fee

33、lings associated with the event. Common feelings include self-pity, pessimism, and loss of interest in life. It affects people of all ages. ESeasonal Affective Disorder(SAD). If you live in the northern latitudes and suffer depression during the winter months, you may suffer from seasonal affective

34、disorder caused by a lack of exposure to sunlight. Doctors arent sure exactly what physiological mechanisms are at work in SAD, but they speculate that depressed feelings and other symptoms may be due to an increase in the release of the hormone meltonin. SAD sufferers feel lethargic and irritable.

35、They may also suffer from chronic headaches, increased appetite, weight gain, and an increased need for sleep. For unknown reasons, SAD is truly a “womans depression,“ in that women make up 70 percent to 80 percent of those affected. Since about half of all SAD sufferers have relatives who also suff

36、er from SAD or other emotional problems, researchers speculate that the problem may be inherited. FBiochemical depression. Doctors arent sure why, but some people develop a biochemically based depression sometime during midlife. Its likely that this type of depression is caused by biochemical proble

37、ms within the brain. The problem usually responds well to antidepressant medication. You may be more likely to develop this type of chemical depression if other members of your family have also suffered from this problem. GDisease or drug-related depression. Some diseases such as AIDS, stroke, chron

38、ic pain, and hypothyroidism(甲状腺功能减退 )can cause depression. In hypothyroidism, the thyroid gland(甲状腺 )malfunctions, leading to too little or no thyroid hormone circulating in the bloodstream. In addition to depression, other symptoms of hypothyroidism include fatigue, weakness, weight gain, impaired

39、memory, and shortness of breath. Fortunately, the depression and other symptoms of hypothyroidism can be effectively treated with adequate doses of thyroid hormone. HCertain drugs such as alcohol, tranquilizers(镇定剂 ), and heart and blood pressure medications, as well as withdrawal from some street d

40、rugs like cocaine, can cause drug-related depression. Some women who take birth control pills find the drugs make them irritable, anxious, and depressed. And a deficiency in some nutrients has been linked to depression. ITeenage depression. Recognizing depression in children is important. Depression

41、 in teenagers may appear somewhat different from adult depression. The teenage years are a period of complicated conflicts that lead many young people to develop negative self-esteem, anxieties, and fears about their future. Some young people become overwhelmed by peer pressures and feelings of isol

42、ation and powerless-ness. Social expectations may be unrealistic, and doing poorly in school can lead to a feeling of rejection. The young person may have experienced a lack of support from family and other significant people and a decrease in his or her ability to cope effectively.(As is the case f

43、or adults, treatment for depression in teenagers may involve a combination of therapies.) JDepression may be related to many factors, including a family history of depression, medical illnesses, alcohol, drugs, gender, and age. Additionally, an individuals self-confidence, personality traits such as

44、 dependency on others or perfectionism and unrealistic expectations may lead to depression. Stressful events, such as death of a spouse or loss of a job, also contribute to depression. Many people with major depression also suffer from intense anxiety. KThere are many theories about the causes of de

45、pression. The social learning theory suggests that lack of positive reinforcement from others may lead to negative self-evaluation and a poor outlook for the future. The psychoanalytic theory suggests that a significant loss(such as of a parent)or a withdrawal of affection in childhood(whether real

46、or perceived)may lead to depression in later life. Interpersonal theory emphasizes the importance of social connections for good mental health. Other theories suggest that unrealistic expectations of oneself and others and loss of self-esteem are essential components leading to depression. LSome ind

47、ividuals may be biologically predisposed to depression; in other words, they may have been born with a tendency to develop depression. Researchers continue to investigate chemical reactions in the body that are controlled by these genes. Depression often runs in families. For example, if one i-denti

48、cal twin suffers from depression, the other twin has a 70 percent chance of also having the illness. MEnvironmental Influences. Researchers view depression as the result of interaction between environmental and biological factors. Depression can be endogenous(internally caused)or exogenous(related t

49、o outside events). Major changes in ones environment, such as a move or job change, or any major loss, such as a divorce or death of a loved one, can bring on depression. Some environmental factors relating to depression include being unemployed, poor, elderly, or alone. Depression changes ones way of looking at ordinary life circumstances. A depressed person tends to exaggerate negative aspec
