Just as Roman gladiators drank the blood of foes to gain strength, modem Olympians have infused the blood of their own to gain endurance. Blood doping, which tainted the triumphs of some Olympians, has at last been banned.
Blood doping, in short, means withdrawal of one unit of a little more of blood from an athlete's system about four to six weeks before a competition. The blood is then stored in a frozen state while the body replenished the lost blood through natural processes. The extracted blood is unfrozen and then pumped back into the athlete's system just before the competition. This increases the body's hemoglobin count, hereby increasing the capacity for oxygen delivery and raising the level of endurance.
A recent colloquium on the ethics of blood doping, summarized in The Physician and Sports Medicine, cited eases of runners getting blood transfusions so they could run fast enough to qualify for Boston Marathon and of blood doping in dog and horse racing.
Blood doping may be surprisingly common among world-class endurance athletes, especially cyclists and runners. Blood doping is cheating and it is now banned by the International Olympic Committee, but it is still impossible to test, and till sure checks are found, one can only count on the personal ethics of the sportspersons concerned.
Does blood doping really work? Buick et al. and Williams et al. have made some studies in the laboratory. In one study, 11 highly trained male track athletes underwent extensive treadmill testing before and alter phlebotomy with re-infusion of 900mi of antilogous freeze-preserved red cells. The blood doping increased the mean hemoglobin concentration 8% (from 15.1% to 16.3% gnm/100ml) , maximal oxygen consumption 5% , and running time to exhaustion 35%. In another study, 12 experienced male distance runners who received 920ml of antilogous blood had a mean 7% increase in hemoglobin concentration and a mean 45-second improvement in time on a 5-mile treadmill run, compared with results after they received 920m1 saline. In the third study, 9 male college students who received two units antilogous blood had a significant increase in hemoglobin concentration and maximal oxygen consumption on a cycle ergo-meter.
It is reasonable to conclude that blood doping does work when properly performed in the laboratory. But does it work in the field?
The problem in determining if blood doping works in the field is that almost all the reports are anecdotal. Whether it works or not, blood doping as it was done for the U.S. Olympic cyclists is to be condemned. Three of the cyclists developed flu-like symptoms 36 hours after transfusion, and one of them, when asked about blood doping, said, "Yeah, I did it. I got sick and it ruined me for the Olympics." To be sure, some of the cyclists who blood-doped won medals, but so did some who refused blood doping. Likewise, not all Olympians who admitted to blood doping were medal winners: an Italian runner who blood-doped for the marathon said he ran poorly and the national cross-country team alleged to have blood-doped ran poorly. In short, one cannot tell from anecdotal reports whether or not blood doping works in the field.
Which of the following statements best expresses the main idea of the passage?
A.Blood doping does afford athletes a competitive advantage though it is not quite safe.
B.Blood doping works in the laboratory, but there is no evidence to show it works in the field.
C.Blood doping is becoming increasingly common in the world of sports.
D.Athletes who Blood-dope for endurance can perform. better than others.

Since pleasure is the first good and natural to us, for this very reason we do not choose every pleasure, but sometimes we pass over many pleasures, when greater discomfort accrues to us as the result of them; and similarly we think many pains better than pleasures, since a greater pleasure comes to us when we have endured pains for a long time. Every pleasure then because of its natural kinship to us is good, yet not every pleasure is to be chosen; even as every pain is also an evil, yet not all are always of a nature to be avoided. Yet by a scale of comparison and by the consideration of advantages and disadvantages we must form. our judgement on all these matters. For the good on certain occasions we treat as bad, and conversely the bad as good.
We must consider that of desires some are natural, others vain, and of the natural some are necessary and others merely natural; and of the necessary some are necessary for happiness, others for the repose of the body, and others for very life.
Unhappiness comes either through fear or through vain and unbridled desire; but if a man curbs these, he can win for himself' the blessedness of understanding. Of desires, all that do not lead to a sense of pain, if they are not satisfied, are not necessary, but involve a craving which is easily dispelled, when the object is hard to procure or they seem likely to produce harm. Wherever in the case of desires which are natural, but do not lead to a sense of pain, if they are not fulfilled, the effort is intense, such pleasures are due to idle imagination, and it is not owing to their own nature that they fail to be dispelled, but owing to the empty imaginings of the man.
The disturbance of the soul cannot be ended nor true joy created either by the possession of the greatest wealth or by honour and respect in the eyes of the mob or by anything else that is associated with causes of unlimited desires. We must not violate nature, but obey her; and we shah obey her if we fulfil the necessary desires and also the natural, if they bring no harm to us, but sternly reject the harmful. The man who follows nature and not vain opinions is independent in all things. For in reference to unlimited desires even the greatest wealth is not riches but poverty.
Insofar as you are in difficulties, it is because you forget nature; for you create for yourself unlimited fears and desires. It is better for you to be free of fear lying upon a pallet, than to have a golden couch and a rich table and be full of trouble.
What does "greater discomfort accrues to us" in Paragraph 1 mean here?
A.We get greater discomfort over a period of time.
B.We are tortured by greater discomfort.
C.Greater discomfort exists in our body.
D.Greater discomfort makes us miserable.

There are certain people who behave in a quite peculiar fashion during the work of analysis. When one speaks hopefully to them or expresses satisfaction with the progress of the treatment, they show signs of discontent and their condition invariably becomes worse. One begins by regarding this as defiance and as an attempt to prove their superiority to the physician, but late one comes to take a deeper and juster view. One becomes convinced, not only that such people cannot endure any praise or appreciation, but that they react inversely to the progress of the treatment. Every partial solution that ought to result, and in other people does result, in an improvement or a temporary suspension of symptoms produces in them for the time being an intensification of their illness; they get worse during the treatment instead of getting better. They exhibit what is known as a "negative therapeutic reaction".
There is no doubt that there is something in these people that sets itself against their recovery, and its approach is dreaded as though it were a danger. We are accustomed to say that the need for illness has got the upper hand in them over the desire for recovery. If we analyze this resistance in the usual way—then, even after fixation to the various forms of gain from illness, the greater part of it is still left over; and this reveals itself as the most powerful of all obstacles to recovery, more powerful than the familiar ones of narcissistic inaccessibility, a negative attitude towards the physician and clinging to the gain from illness.
In the end we come to see that we are dealing with what may be called a "moral" factor, a sense of guilt, which is finding satisfaction in the illness and refuses to give up the punishment of suffering. We shall be right in regarding this disencouraging explanation as final. But as far as the patient is concerned this sense of guilt is dumb; it does not tell him he is guilty, he feels iii. This sense of guilt expresses itself only as a resistance to recovery which it is extremely difficult to overcome. It is also particularly difficult to convince the patient that this motive lies behind his continuing to be iii; he holds fast to the more obvious explanation that treatment by analysis is not the fight remedy for his case.
According to the author, it would be more reasonable to think that the patients who exhibit dissatisfaction with the treatment are
A.openly resisting the treatment of the physician.
B.intentionally holding the physician in contempt.
C.spontaneously responding contrary to the physician's expectations.
D.purposely disregarding the praise or appreciation by the physician.

Pain is easier to endure if you know you can end it. Speakers at a session on pain at the British Association's psychology section have new evidence to support this idea for two common experiences of pain: in childbirth and at the dentist's. On the other side of the coin, their inability to control pain may explain why some people with continual pain have psychological problems as well.
Dr. J. Robinson found out about the phenomenon of self-controlled pain almost by accident. He was studying the effects of analgesics used to control pain during childbirth and as part of the experiment made it possible for women having their child to press a button which gave an automatic injection—instead of having all injections made by the doctor. Afterwards these women did not say that they had less pain than other women in childbirth, but they did use considerable less of the drug.
J. Atkins, a dental surgeon, has observed a similar phenomenon. As part of their efforts to make dentistry painless, Atkins and researchers at Aston University in Birmingham offered patients a switch they could flip to turn off the dentist's drill whenever they chose. But, after trying the switch on 50 patients Atkins gave up; none of the patients had ever flipped the switch.
Perhaps the extra endurance was because the Aston team also use other methods to make dentistry painless. Apparently few other dentists are so considerate. The end result, according to the Birmingham survey, is that British people avoid going to the dentist, with the consequence that almost 30% of people in England and Wales have lost all their teeth, and more than seven out of ten have lost at least six teeth. Less than half of the public pay regular visits to the dentist. To find out why, Atkins and psychologist Cumberbatch interviewed a sample of patients attending a dental hospital. The most common reason people gave for not having dental check-ups were fear and pain.
By using a little care and taking time to explain what will happen, Atkins feels, dentists could overcome these fears. There are techniques for giving injections without pain, and a "calm unhurried approach" to drilling can make that painless, too.
Sadly, few dentists seem to take much trouble with their patients. "I am not nervous when I go to the dentist, and I do not have any pronounced sympathy for those who are, " said one dentist. "I tend to take the point of view that they are being unreasonable at my expense."
The passage most possibly comes from______.
A.a medical textbook
B.a psychology textbook
C.a popular magazine
D.a serious magazine
