2 . More scientists are exploring cellular senescence(衰老)—a state in which cells(细胞)no longer divide. Senescent cells, which build up in older bodies, have a link to age-related conditions such as dementia(痴呆) disease.

Scientists are exploring drugs that treat senescent cells. But the most promising tool against the bad effects of senescent cells, experts say, is exercise.

Today, LeBrasseur, who directs a center on aging at Mayo, says exercise is “the most promising tool that we have” for good health in late life, and its power spreads to our cells. Research suggests exercise prevents the buildup of senescent cells, helping the immune(免疫的)system clear them and fight the cell damage that can affect aging.

Last year, LeBrasseur led a study that provided the first sign in humans that exercise greatly affected senescence. It cut signs in the bloodstream of the effects of senescent cells in the body.

After a 12-week exercise program, researchers found that older adults had cut signs of senescence and improved body strength, physical ability and reported health.   A recent study collects even more facts—in animals and humans—for exercise as a treatment to fight against senescence cells.

While such studies are not well-known outside scientific circles, many older adults connect exercise with youthfulness. Farmer Mike Gale, 81, put in a track and field throwing circle on his large farm in California. He and some of his friends throw the discus(铁饼) and use other exercise equipment. “I'd like to be competing in my 90s,” Gale says. “Why not?”

95-year-old Richard Soller says exercise keeps him fit enough to deal with what comes his way—including the discovery that his wife of 62 years had developed dementia. The two sometimes walk the streets of their neighborhood together, holding hands. “Do as much as you can,” he says. “That should be the goal for anyone to stay healthy.”

10 . Did you know that the color of uniforms can influence the performance of an athlete? It may sound strange, but a study suggests this might be true.

Two British scientists studied the results of four sports in the 2004 Athens Olympic Games where the athletes had been given either a red or a blue uniform. They discovered that when there was a big difference in the score, color had no influence on the result. But if it was a close match, the athlete in a red uniform was more likely to win. Then they looked at the uniforms of the soccer teams at the Euro 2004 tournament. Again, teams wearing red won more games.

The two scientists got their idea from earlier studies of wild animals. It had been discovered that when a male show red on its body, it sends a signal of its power and strength. For example, in many kinds of monkey, the more the male shows off its red scars, the more females it can attract.

Based on this fact, the British scientists thought that the idea might work for humans, too. According to them, when an athlete sees a competitor in a red uniform, he gets a feeling that his competitor could be stronger than him. And that kind of feeling may have a bad influence on the player’s performance in the actual game.

Although the idea is Interesting, most people don’t accept that color signals in the animals world can really be useful to humans in sports. They think that it is unreasonable to develop an idea based on such a small number of examples. Much more research has to be done to prove the influence of uniform colors on the performance of athletes.

1. What did the scientists find out about the 2004 Athens Olympic Games?

A．Athletes played equally well in four sports.

B．Game results had a big influence on the athletes.

C．Athletes dressed in red scored more in a close match.

D．There was a big difference in red and blue team’s scores.

2. What may the red scars of a male animal suggest?

A．It is quite strong.	B．It is a failure.
C．It has power over other males.	D．It has attracted a lot of females.

3. The underlined part “that kind of feeling” in the text refers to a feeling of ________.

A．weakness

B．pride

C．danger

D．shame

4. What is most people’s opinion to the scientists’ idea?

A．Interested.

B．Satisfied.

C．Doubtful.

D．Thankful.
