22、nses of lower animals too. In one experiment, for example, behavioral immunologist Mark Laudenslager, at the University of Denver, gave mild electric shocks to 24 rats. Half the animals could switch off the current by turning a wheel in their enclosure, while the other half could not. The rats in th

23、e two groups were paired so that each time one rat turned the wheel it protected both itself and its helpless partner from the shock. Laudenslager found that the immune response was depressed below normal in the helpless rats but not in those that could turn off the electricity. What he has demonstr

24、ated, he believes, is that lack of control over an event, not the experience itself, is what weakens the immune system.Other researchers agree. Jay Weiss, a psychologist at Duke University School of Medicine, has shown that animals who are allowed to control unpleasant stimuli don t develop sleep di

25、sturbances or changes in brain chemistry typical of stressed rats. But if the animals are confronted with situations they have no control over, they later behave passively when faced with experiences they can control. Such findings reinforce psychologists suspicions that the experience or perception

26、 of helplessness is one of the most harmful factors in depression.One of the most startling examples of how the mind can alter the immune response was discovered by chance. In 1975 psychologist Robert Ader at the University of Rochester School of Medicine conditioned mice to avoid saccharin by simul

27、taneously feeding them the sweetener and injecting them with a drug that while suppressing their immune systems caused stomach upsets. Associating the saccharin with the stomach pains, the mice quickly learned to avoid the sweetener. In order to extinguish this dislike for the sweetener, Ader re-exp

28、osed the animals to saccharin, this time without the drug, and was astonished to find that those mice that had received the highest amounts of sweetener during their earlier conditioning died. He could only speculate that he had so successfully conditioned the rats that saccharin alone now served to

29、 weaken their immune systems enough to kill them.（分数：5.00）(1).Laudenslager s experiment showed that the immune system of those rats who could turn off the electricity _ .A. was strengthened B. was not affectedC. was altered D. was weakened（分数：1.00）A.B.C.D.(2).According to the passage, the experience

30、 of helplessness causes rats to _ .A. try to control unpleasant stimuli B. turn off the electricityC. behave passively in controllable situations D. become abnormally suspicious（分数：1.00）A.B.C.D.(3).The reason why the mice in Ader s experiment avoided saccharin was that _ .A. they disliked its taste

31、B. it affected their immune systemsC. it led to stomach pains D. they associated it with stomach（分数：1.00）A.B.C.D.(4).The passage tells us that the most probable reason for the death of the mice in Ader s experiment was that _ .A. they had been weakened psychologically by the saccharinB. the sweetene

32、r was poisonous to themC. their immune systems had been altered by the mindD. they had taken too much sweetener during earlier conditioning（分数：1.00）A.B.C.D.(5).It can be concluded from the passage that the immune systems of animals _ .A. can be weakened by conditioning B. can be suppressed by drug i

33、njectionsC. can be affected by frequent doses of saccharin D. can be altered by electric shocks（分数：1.00）A.B.C.D.九、Passage 2(总题数：1，分数：5.00)The video game presents a world - a much simpler world than our own, where success is very clearly defined and, for a time, easily attained. Through practice, a p

34、layer can control this world for a while, He can escape from the anxieties of real life into a place where his own actions always count, where he can be a hero.

38、d more adolescents are crowded in electronic game houses for days to experience what they perceive to be excitement. In due course, they train their abilities in confronting with new situations, and whats more, they learn how to communicate with their targeted rivals, in a novel and friendly way. Bu

39、t there is such a large amount of criticism concerning the electronic games that they are generally seen as a way of infecting hostility and belligerence.
