After decades of cat-and-mouse between athletes and the word anti-doping agency (WADA), athletes found what they must have believed to be the ultimate (终极的) doping agent: their own blood. To enhance athletic performance with your own blood, you draw your blood and store it in a freezer. Your body compensates by creating more blood. Then, months later, just before a competition, you can re-inject (注射) the old blood for a boost. As the red-blood-cell count goes up, so does an athlete’s ability to absorb oxygen. The more oxygen you get with each breath, the more energy your body is able to bum and the better you are able to perform.
Although the enhancement is small compared to actual drugs, it can be the difference between a gold medal and a silver medal. Best of all, “extra blood” was never something WADA tested for.
But WADA wasn’t going to sit by and be fooled. What it came up with in response might be a solution to stop doping once and for all: an athlete biological passport (ABP). The idea is to record some biological features of an athlete through testing done at regular intervals. The biological passport’s partial implementation (实施)—recording blood and steroid levels—began in January 2014.
When all necessary biological features are finally combined, WADA will no longer need to worry about finding new methods to detect a drug. It will only have to detect (检测) resulting changes in the body. In the case of blood doping, if the athlete’s normal red-blood-cell count is, say, 47%, but then is found to be 51% after a competition, cheating may have been involved.
WADA is confident that the biological passport could even prevent genetic changes—the ultimate, ever-lasting enhancement—which are surely coming next. If an athlete inserts a performance enhancing gene, it will probably leave detectable changes in the body, that would differ from the athlete’s feature in the biological passport.
1.What does the underlined word “boost” in Paragraph 1 probably mean?
A. Treatment. B. Test.
C. Promotion. D. Recovery.
2.What words can be used to describe the athlete biological passport?
A. Complex and expensive. B. Simple and thorough.
C. Flexible an popular. D. Controversial and confusing.
3.What s the writer’s attitude towards the solution of anti-doping mentioned in the text?
A. Suspicious. B. Positive.
C. Worried. D. Unconcerned.
4.What can we infer about the athlete biological passport?
A. It can only be used to test blood doping.
B. It has been completely adopted by WADA.
C. It is the excellent alternative of many athletes.
D. It’s a good choice to ensure faimess in sports

Short Skirts Are Out!
After decades of skimpy skirts and sleeveless tops on game days, some schools in the US are saying cheerleader uniforms will have to meet stricter dress codes when they are worn in class.
In Lake County, Florida, cheerleaders with uniforms too skimpy for the code are being asked to wear long shorts or trousers under their skirts and a T-shirt under the sleeveless tops, according to a district memo. Principals at two of Lake’s eight high schools – Leesburg and Lake Minneola – are not allowing the outfits in school at all.
Michelle Thomas, a cheerleader at Leesburg High School, was disappointed when she learned she couldn’t wear her outfit to school on game days.
“It shows that we’re a team just like all the other sports,” she said.
But the school administrators did not agree. “During the educational portion of the day, they have to meet the dress code just like every other student,” said school board chairwoman Debbie Stivender, who ordered the staff to bring the outfits into line with the dress code.
Bare midriffs are banned across the state by the Florida High School Athletic Association, but no state rules mention cheerleader miniskirts. Sheila Noone, a spokeswoman for cheerleading uniform company Varsity Brands, says the outfits haven’t become more revealing over the last 10 years. She says that the short skirts are designed to help the girls jump and kick.
“Cheerleading is athletic,” Noone said. “There’s a lot of jumping, so you won’t want a knee-length skirt that might hamper a tie touch.”
Most cheerleaders were sad to hear the news, but say they’ll follow the rules. Even male cheerleaders, whose pants and tops meet dress codes, chose not to wear their outfits to show unity.
“I understanding, because they are kind of short,” said Holly Bishop, 14, a Lake Minneola High School cheerleader, about her miniskirt. “It would have been really, really cool to wear them to school.”
1.According to the new dress codes for cheerleaders in some American schools, __________.
| A．bare midriffs are banned |
| B．cheerleading miniskirts are banned |
| C．cheerleader uniforms have switched from skirts to trousers |
| D．cheerleaders have to make their uniforms less revealing |
2.Which of the following statement is TRUE according to the article?
| A．School administrators believe cheerleader uniforms do not match school dress codes. |
| B．Most cheerleaders show understanding of the new dress codes. |
| C．Sheila Noone believes that cheerleading miniskirts are not revealing. |
| D．School administrators don’t take cheerleading seriously. |
3.Some cheerleaders are not happy about the news because __________.
| A．they hate the dress codes that other sports have |
| B．they consider their uniforms special and cool |
| C．they want to wear revealing clothes |
| D．they will have to buy new uniforms |

In the past decade the popularity of rock climbing has greatly increased, and so has the number of injuries. It has been estimated that rock climbing is now enjoyed by more than 9 million people in the US each year. Study findings revealed a 65% increase in the number of patients that were treated in US emergency departments for rock climbing-related injuries between 1991 and 2012.
The study, published in the online issue of the American Journal of Preventive Medicine, found that about 40,000 patients were treated in US emergency departments for rock climbing-related injuries between 1991 and 2012. The most common types of rock climbing –related injuries were fractures(骨折) and sprains （扭伤）。The ankle was the most common body part to be injured (40%). Climbers in the study ranged in age from 2 to 74, with an average age of 26. The study also found that women took up a quarter of the injuries.
Falls were the primary reason for injury with over three-quarters of the injuries occurring as the result of a fall. The severity of fall-related injuries had a lot to do with the height of the fall. Patients who were injured after falling from a height over 20 feet were 10 times more likely to be treated than patients who were injured falling from 20 feet or lower.
“We found that the climbers who fell from heights higher than 20 feet took up 70 percent of the patients treated for a rock climbing-related injury,” explained the study author Lara McKenzie, PhD, director at the Center for Injury Research and Policy at Nationwide Hospital. “This trend, combined with the fact that rock climbers have a higher hospitalization rate than other sports and recreational injuries, demonstrates the need to increase injury prevention efforts for climbers.”
1.Which body part is most likely to get injured for a climber ?
A. The arm B. The knee
C. The ankle D. The hand
2.How many women climbers in American got injured while climbing a rock between 1991 and 2012 ？
A.About 40,000 B.About 30,000
C.About 20,000 D.About 10,000
3.The severity of climbers’ fall-related injures is mainly related to ______.
A. the height of the fall.
B. the climber’s age.
C. the climber’s health condition
D. the climber’s climbing experience.
4.The underlined word “demonstrates” in the last paragraph can be replaced by ________.
