3 . Cheating in sport is as old as sport itself. The athletes of ancient Greece used potions to strengthen themselves before a contest, and their modern counterparts have everything from anabolic steroids (类固醇) to growth hormones with which to_________their bodies. These days, however, such stimulants are_________, and those athletes must therefore face the challenges of anti-doping (反兴奋剂) agencies.

The agencies have had remarkable success. Testing for anabolic steroids was introduced in the 1970s, and the incidence of cheating seems to have_________dramatically as a result. The tests, however, are not entirely_________. And a study just published in the Journal of Clinical Endocrinology & Metabolism by Jenny Jakobsson Schulze and her colleagues at the Karolinska Institute in Sweden suggests that an individual’s genetic make-up could_________the tests in two different ways. One genotype, may allow athletes who use anabolic steroids to escape detection altogether. Another may actually be convicting (给……定罪) the innocent.

The test employed for testosterone (睾酮素) abuse usually relies on measuring the_________of two chemicals found in the urine (尿液): TG. and EG.. Any ratio above four of the former to the latter is considered_________and leads to more tests. However, the production of TG is controlled by a gene called UGT2B17. This gene comes in two varieties, one of which has a part missing and therefore does not work properly. A person may thus have none, one or two working copies of UGT2B17, since he inherits one copy from each parent. Dr. Schulze_________that different numbers of working copies would produce different test results. She therefore gave healthy male volunteers whose genes had been examined a single 360mg shot of testosterone — the standard dose for legal medical use — and checked their urine to see whether the shot could be_________.

The result was remarkable. Nearly half of the men who carried no functional copies of UGT2B17 would have gone undetected in the standard doping test.____________, 14% of those with two functional copies of the gene were over the detection threshold (门槛) before they had even received an injection. The researchers estimate this would give a ____________rate of 9% in a random population of young men.

Dr. Schulze also says there is substantial____________variation in UGT2B17 genotypes. Two-thirds of Asians have no functional copies of the gene which means they have a naturally____________ratio of TG to EG, compared with under a tenth of Caucasians (白种人) — something the anti-doping bodies may wish to take into account.

In the meantime, Dr. Schulz’s study does seem to offer innocents a way of____________themselves. Athletes who will travel to Paris for the Olympic games may be wise to travel armed not only with courage and the “spirit of Olympianism”, but also with a copy of their____________, just in case.

4 . The public must be able to understand the basics of science to make informed decisions. Perhaps the most dramatic example of the negative consequences of poor communication between scientists and the public is the issue of climate change, where a variety of factors has contributed to widespread mistrust and misunderstanding of scientists and their research. The issue of climate change also illustrates how the public acceptance and understanding of science (or the lack of it) can influence governmental decision-making with regard to regulation, science policy and research funding.

However, the importance of effective communication with a general audience is not limited to hot issues like climate change. It is also critical for issues such as the genetic basis for a particular behavior or the use of animal models because in these areas, the public understanding of science can also influence policy and funding decisions. Furthermore, with continuing scientific advances, more non-scientists will need to be able to analyze complex scientific information to make decisions that directly affect their quality of life.

Science journalism is the main channel for the popularization of scientific information among the public. Much has been written about how the relationship between scientists and the media can shape the efficient communication of scientific advances to the public. Good science journalists are specialists in making complex topics accessible to a general audience, while sticking to scientific accuracy. Unfortunately, pieces of science journalism can also oversimplify and generalize their subject material. As a result, the basic information conveyed is difficult to understand or obviously wrong.

Even though scientists play a part in conveying information to journalists and ultimately the public, too often the blame for ineffective communication is placed on the side of the journalists. I believe that, at least in part, the problem lies in places other than the interaction between scientists and members of the media. It exists because we underestimate how difficult it is for scientists to communicate effectively with a diversity of audiences, and most scientists do not receive formal training in science communication.

8 . How does a person become an Olympic champion? In reality, a combination of biological, environmental, and psychological elements, as well as training and practice, all go into making a super athlete.

Perhaps the most important element involved in becoming an outstanding athlete is genetic. Most Olympic competitors are equipped with certain physical characteristics that make them different from the average person. Olympic weightlifters, for example, have a large number of fast- twitch fibers (快速收缩肌肉纤维) in their muscles. These allow them to lift hundreds of kilos from the ground and over their heads in seconds. Surprisingly, a large, muscular body is not the main requirement to do well in this sport. It is more important to have a large number of fast-twitch fibers in the muscles.

The legs of an outstanding marathon runner, on the other hand, might contain up to 90 percent slow-twitch muscle fibers. When we exercise long or hard, it’s common to experience tiredness, muscle pain, and difficulty breathing. These feelings are caused when the muscles produce high amounts of a substance called lactate and can’t remove it quickly enough. Athletes with many slow-twitch muscle fibers seem to be able to clear the lactate from their muscles faster as they move.

Some athletes’ abilities are naturally enhanced by their environment. Those raised at high altitudes (海拔高地) in countries such as Kenya have blood rich in hemoglobin (血红素). Large amounts of hemoglobin carry oxygen around the body faster, enabling these athletes to run better. Although genes, environment, and even culture play a part in becoming an outstanding athlete, training and practice are needed to succeed. Marathon runners may be able to control tiredness and keep moving for long periods of time, but they must train to reach their goals. Weightlifters and gymnasts perfect their skills by repeating the same motions again and again until they become automatic. Greg Louganis, winner of four Olympic diving gold medals, says divers must train the same way to be successful: “You have less than three seconds from takeoff until you hit the water, so it has to be reflex (对刺激的本能反应). You have to repeat the dives hundreds, maybe thousands, of times.” Training this way requires an athlete to be not only physically fit but psychologically healthy as well. Otherwise, they couldn’t handle the training loads.

10 . Laura walked towards the man. “It is terribly cold,” she said.

“Colder than ever,” the man said. “Now tell me what you want.” He stared at Laura for a few seconds and then grinned, “Maybe you’d like to come inside and warm up.”

“No. No, I don’t want to come in.” She took a deep breath. “I just wanted to know if you’re interested in selling your dog.”

“That worthless mutt?” The man pointed to a dog in the yard and laughed for a few seconds, then suddenly stopped. “I was just joking about the worthless part. He’s a pretty good dog. Yeah. I might be interested.”

“Well, he’s the kind of dog I’m looking for. And it doesn’t seem like you’re too fond of him. I mean he’s tied up outside. I don’t see any food or water.”

“You just wait a minute. I take good care of that dog. The guy I got him from said he was a trained guard dog. The trouble is, the stupid thing doesn’t even bark when strangers come around. But then I guess that wouldn’t matter to you. You’re probably just looking for a pet, huh?”

“Yeah. Well, here’s your chance to get rid of him. I’ll give you twenty dollars.”

“You expect me to sell a purebred guard dog for twenty dollars?” the man snorted (哼着鼻子说). “Fifty dollars. That’s my price. You bring me fifty dollars, honey, and you got yourself a dog.” He smiled. “Sure you don’t want to come in?”

Laura shook her head. “I’ll be back with the money.” Breakfast forgotten, she searched for and found a cash machine four blocks away. I can’t afford this, she thought as she punched the numbers into the machine. The dog will need a vet, and where am I going to get the money for that? Her fears wore off as she pictured the dog, curled up, not outside on the cold, hard ground, but in front of a glowing fireplace. Blue ceramic bowls filled with food and water sat in the corner of the kitchen, and she saw him, head held high, matching her stride on their daily walk.

With the money in her purse, she hurried back to the man’s house.
