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.

Everything has two sides. One side of SARS is already clear. It is a deadly disease, which causes fear. There were 2601 cases recorded on the Chinese mainland on April 24, according to government figures. Some 115 people have died and numbers keep rising.
But, there's another side.
SARS is a reminder of how fragile (脆弱的)life can be. Suddenly, it's not just the old people who are thinking about death. Everyone now realizes there might not always be a tomorrow.
Li Ping, a Senior 3 student in Taiyuan, Shanxi Province, came into contact(接触)with a suspected(疑似)SARS patient in mid-April. He was told to stay at home for at least two weeks. "Watching TV about more and more SARS patients dying, ! never knew that death could be so close. Life is Valuable and I am going to treasure every single day." he said.
SARS teaches people to be grateful, not only for their own lives, but also for others. Doctors and nurses, for example, have to spend all their time with infected(被感染的)patients. As a result, more than 20 percent of SARS cases in China are medical workers.
Liu Yu, a Senior 2 student of Beijing No. 5 Middle School, wants to be a doctor when he grows up. "Although they certainly know of the dangers, doctors and nurses remain bravely dedicated(致力于)to saving people's lives. I was deeply moved by what they have done. I think they are real heroes." he said.
SARS also teaches sympathy(同情). The past few weeks have been terrible for Chinese people. But there are far worse things than SARS in this world, such as war, earthquakes and murders. Think of the Iraqis, who have been living terrible lives for 20 years. Think of how the Americans felt on 9. 11.
And finally, SARS offers the chance to grow. All different types of people and government officials are joining together to cope with this difficult time. When this passes, China and its people, will have learned great lessons.
The story of Li Ping is given in this passage mainly to ______.
A．tell us the hardship of life
B．tell us the fragility of life
C．tell the cruelty of SARS
D．tell us the joy of life
