21、smoking and alcohol and marijuana use increased among residents of Manhattan during the 58 weeks after the terrorist attacks on the World Trade Center winch took place on September 11, 2001. Almost one-third of the nearly 1,000 persons interviewed reported an increased use of alcohol, marijuana, or
22、cigarettes following the September 11th attacks. The largest increase was in alcohol use. About one-fourth of the respondents said they were drinking more alcohol in the weeks after September 11; about 10% reported an increase in smoking, and 3.2% said they had increased their use of marijuana.The i
23、nvestigators found survey participants by randomly dialing New York City phone numbers and screened potential respondents for Manhattan residents living in areas close to the World Trade Center. Interviews were conducted with 988 individuals between October 16 and November 15, 2001. Participants wer
24、e asked about their cigarette smoking, alcohol drinking, and marijuana use habits before and after September 11. During the week prior to September 11, 2001, 22. 6% of the participants reported smoking cigarettes, 59. 1% drinking alcohol, and 4.4% using marijuana. After September 11th, 23.4% reporte
25、d smoking cigarettes, 64. 4% drinking alcohol, and 5.7% smoking marijuana. Among those who smoked, almost 10% reported smoking at least an extra pack of cigarettes a week and among those who drank alcohol, more than 20% reported imbibing at least one extra drink a day.The researchers found that peop
26、le who reported an increase in substance abuse were more likely to suffer from post traumatic stress disorder (PTSD) and from depression. People who reported an increase in cigarette smoking or marijuana use were also more likely to have both PTSD and depression, while those who reported an increase
27、 in alcohol use were more likely to have depression only. Persons who were living closer to the World Trade Center were more likely to increase their cigarette smoking, but other factors such as being displaced from home, losing possessions during the attacks, or being involved in the rescue efforts
28、 were not consistently associated with increased substance use. Symptoms of panic attack were associated with an increase in the use of all substances.Increase in substance abuse did not differ significantly between men and women or among racial or ethnic groups. Demographic factors such as age, mar
29、ital status, and income seemed to play a more critical role in determining if the events of September 11th led to an increase in substance use.（分数：5.00）(1).The survey results suggest that the largest increase in substance use should be _.（分数：1.00）A.alcohol.B.marijuana.C.cigarettes.D.cocaine.(2).The
30、people who took part in the survey were _.（分数：1.00）A.randomly selected United States citizens.B.randomly selected New York City citizens.C.randomly selected Manhattan residents who live close to the World Trade Center.D.randomly selected American citizens who witnessed the terrorist attack.(3).The a
31、uthor is trying to show that _.（分数：1.00）A.use of substances may vary from time to time.B.abuse of certain substances is harmful for health.C.the attack of September 11th has left incurable harm to peoples mental health.D.terrorist attack increased anxiety and sense of insecurity among residents.(4).
32、What can be said about substance abuse after September 11?（分数：1.00）A.People who reported an increase in alcohol use were more likely to have PTSD.B.People who were living closer to World Trade Center were most likely to increase cigarette smoking.C.Displacement from home and involvement in rescue ef
33、forts were consistently associated with increased substance use.D.Symptoms of panic attach were unrelated with increased use of substances.(5).What can be inferred from the last paragraph?（分数：1.00）A.Demographic information such as gender, race and marital status was not collected.B.Gender and race d
34、o not have much effect on the amount of substance abuse.C.Age and marital status do not make any difference on substance abuse.D.Income is a better predictor of substance abuse than age.BTEXT 2/BBefore a big exam, a sound nights sleep will do you more good than poring over textbooks. That, at least,
35、 is the folk wisdom. And science, in the form of behavioral psychology, supports that wisdom. But such behavioral studies cannot distinguish between two competing theories of why sleep is good for the memory. One says that sleep is when permanent memories form. The other says that they are actually
36、formed during the day, but then “edited“ at night, to flush away what is superfluous.To tell the difference, it is necessary to look into the brain of a sleeping person, and that is hard. But after a decade of painstaking work, a team led by Pierre Maquet at Liege University in Belgium has managed t
37、o do it. The particular stage of sleep in which the Belgian group is interested in is rapid eye movement (REM) sleep, when brain and body are active, heart rate and blood pressure increase, the eyes move back and forth behind the eyelids as if watching a movie, and brainwave traces resemble those of
38、 wakefulness. It is during this period of sleep that people are most likely to relive events of the previous day in dreams.Dr. Maquet used an electronic device called PET to study the brains of people as they practiced a task daring the day, and as they slept during the following night. The task req
39、uired them to press a button as fast as possible, in response to a light coming on in one of six positions. As they learnt how to do this, their response times got faster. What they did not know was that the appearance of the lights sometimes followed a pattern-what is referred to as “artificial gra
40、mmar“. Yet the reductions in response time showed that they learnt faster when the pattern was present than when there was not.What is more, those with more to learn (i. e. , the “grammar“, as well as the mechanical task of pushing the button) have more active brains. The “editing“ theory would not
41、predict that, since the number of irrelevant stimuli would be the same in each case. And to eliminate any doubts that the experimental subjects were learning as opposed to unlearning, their response times when they woke up were even quicker than when they went to sleep.The team, therefore, concluded
42、 that the nerve connections involved in memory are reinforced through reactivation during REM sleep, particularly if the brain detects an inherent structure in the material being learnt. So now, on the eve of that crucial test, maths students can sleep soundly in the knowledge that what they will re
43、member the next day are the basic rules of algebra and not the incoherent talk from the radio next door.（分数：5.00）(1).Researchers in behavioral psychology are divided with regard to _.（分数：1.00）A.how dreams are modified in their courses.B.the difference between sleep and wakefulness.C.why sleep is of
44、great benefit to memory.D.the functions of a good nights sleep.(2).As manifested in the experimental study, rapid eye movement is characterized by _.（分数：1.00）A.intensely active brainwave traces.B.subjects quicker response times.C.complicated memory patterns.D.revival of events in the previous day.(3
45、).By referring to the artificial grammar, the author intends to show _.（分数：1.00）A.its significance in the study.B.an inherent pattern being learnt.C.its resemblance to the lights.D.the importance of nights sleep.(4).In their study, researchers led by Pierre Maquet took advantage of the technique of
46、_.（分数：1.00）A.exposing a long-held folk wisdom.B.clarifying the predictions on dreams.C.making contrasts and comparisons.D.correlating effects with their causes.(5).What advice might Maquet give to those who have a crucial test the next day?（分数：1.00）A.Memorizing grammar with great efforts.B.Studying
47、textbooks with close attention.C.Having their brain images recorded.D.Enjoying their sleep at night soundly.BTEXT 3/BWhen a disease of epidemic proportions rips into the populace, scientists immediately get to work, trying to locate the source of the affliction and find ways to combat it.
