Passage Three
Questions 31 to 35 are based on the following passage.
Crying is hardly an activity encouraged by society. Tears, be they of sorrow, anger, on joy, typically make Americans feel uncomforuble and embarrassed. The shedder of tears is likely to apologize, even when a devastating (毁灭性的) tragedy was the provocation. The observer of tears is likely to do everything possible to put an end to the emotional outpouring. But judging form recent studies of crying behavior, links between illness and crying and the chemical composition of tears, both those responses to tears are often inappropriate and may even be counterproductive.
Humans are the only animals definitely known to shed emotiomal tears. Since evolution has given rise to few, if any, purposeless physiological responset, it is logical to assume that crying has one or more functions that enhance survival.
Although some observers have suggested that crying is a way to clicit assistance form others (as a crying baby might from its mother), the shedding of tears is hardly necessary to get help. Vocal cries would have been quite enough, more likely than tears to gain attention, So, it appears, there must be something special about tears themselves.
Indeed, the new studies suggest that emotional tears may play a direct role in alleviating stress, University of Minnesota researchers who are studying the chemical composition of tears have recently isolated two important chemicals from emotional tears. Both chemicals are found only in tears that are shed in response to cmotion. Tears shed because of exposure to =cut onion would contain no such substance.
Researchers at several other institutions are investigating the usefulness of tears as a means of diagnosing human ills and monitoring drugs.
At Tulane University’s Teat Analysis Laboratory Dr.Peter Kastl and his colleagues report that they can use tears to detect drug abuse and exposure to medication(药物), to determine whether a contact lens fits properly of why it may be uncomfortable, to study the causes of “dry eye” syndrome and the effects of eye surgery, and perhaps even to measure exposure to environmental pollutants.
At Columbia University Dt.Liasy Faris and colleagues are studying tears for clues to the diagnosis of diseases away from the eyes. Tears can be obtained painlessly without invading the body and only tiny amounts are needed to perform highly refined analyses.
31. It is known from the first paragraph that ________.
A) shedding tears gives unpleasant feelings to American
B) crying may often imitate people or even result in tragedy
C) crying usually wins sympathy from other people
D) one who sheds tears in public will be blamed
32. What does “both those responses to tears”(Line 6, Para, 1) refer to?
A) Crying out of sorrow and shedding tears for happiness.
B) The embarrassment and unpleasant sensation of the observers.
C) The tear shedder’s apology and the observer’s effort to stop the crying.
D) Linking illness with crying and finding the chemical composition of tears.
33. “Counterproductive” (Lines 6-7, Para,1) very probably means “________”.
A) having no effect at all
B) leading to tension
C) producing disastrous impact
D) harmful to health
34. What does the author say about crying?
A) It is a pointless physiological response to the environment.
B) It must have a role to play in man’s survival.
C) It is meant to get attention and assistance.
D) It usually produces the desired effect.
35. What can be inferred from the new studies of tears?
A) Emotional tears have the function of reducing stress.
B) Exposure to excessive medication may increase emotional tears.
C) Emotional tears can give rise to “dry eye” syndrome in some cases.
D) Environmental pollutants can induce the shedding of emotional tears.
Passage Four
Questions 36 to 40 are based on the following passage.
It is no secret among athletes that in order to improve performance you’ve got to work hard. However, hard training breaks you down and makes you weaker, It is rest that makes you stronger. Improvement only occurs during the rest period following hard training. This adaptation is accomplished by improving efficiency of the heart and certain systems within the muscle cells. During recovery periods these systems build to greater levels to compensate for the stress that you have applied. The result is that you are now at a higher level of performance.
If sufficient rest is not included in a training program, imbalance between excess training and inadequate rest will occur, and performance will decline. The “overtraining syndrome(综合症)” is the name given to the collection of emotional, behavioral, and physical symptoms due to overtraining that has persisted for weeks to months. It is marked by cumulative exhaustion that persists even after recovery periods.
The most common symptom is fatigue. This may limit workouts and may be present at rest. The athlete may also become moody, easily imitated, have altered sleep patterns, become depressed, or lose the competitive desire and enthusiasm for the sport, Some will report decreased appetite and weight loss. Physical symptoms include persistent muscular soreness, increased frequency of viral (病毒性的) illnesses, and increased incidence of injuries.
The treatment for the overtraining syndrome is rest. The longer the overtraining has occurred, the more rest required, Therefore, early detection is very important, If the overtraining has only occurred for a short period of time (e.g. 3-4 weeks) then interrupting training for 3-5 days is usually sufficient rest. It is important that the factors that lead to overtraining be identified and corrected. Otherwise, the overtraining syndrome is likely to recur. The overtraining syndrome should be considered in any athlete who manifests symptoms of prolonged fatigue and whose performance has leveled off or decreased. It is important to exclude any underlying illness that may be responsible for the fatigue.
36. The first paragraph of the passage tells us that ________.
A) the harder an athlete trains, the better his performance will be
B) rest after vigorous training improves an athlete’s performance
C) strict systematic training is essential to an athlete’s top performance
D) improvement of an athlete’s performance occurs in the course of training
37. By “overtraining” the author means ________.
A) a series of physical symptoms that occur after training
B) undue emphasis on the importance of physical exertion
C) training that is not adequately compensated for by rest
D) training that has exceeded an athlete’s emotional limits
38. What does the passage tell us about the “overtraining” syndrome?
A) It occurs when athletes lose interest in sports.
B) It appears right after a hard training session.
C) The fatigue it results in is unavoidable in the athlete’s training process.
C) It manifests itself in fatigue which lingers even after a recovery period.
39. What does the phrase “level off” (Line 7, Para,4)most probably mean?
A) Slow down.
B) Become dull.
C) Stop improving.
D) Be on the decline.
40. The author advises at the end of the passage that ________.
A) overtraining syndrome should be treated as a serious illness
B) overtraining syndrome should be prevented before it occurs
C) an athlete with overtraining syndrome should take a lengthy rest
D) illness causing fatigue should not be mistaken for overtraining syndrome
