Somewhere in the highlands of Afghanistan, a hungry fox pounces （猛扑）on a tasty-looking leopard gecko （豹纹 壁虎）.But the lizard has a get — out — of — jail — free card: a separable tail. The dropped part waves in an energetic but uncontrolled way around long enough to distract the fox, allowing the gecko itself to run off and hide.

Leopard geckos are one of a few lizard species that possess this ability, known as autotomy （自切）.The technique is effective, but the tail can account for about a quarter of the lizard's body mass. So how do these animals adapt to losing so much of it that quickly?

When geckos lose their tail, they "take this more sprawled posture （四肢伸开的姿势）"and walk with their limbs spread out farther from their body, says Chapman University biologist Kevin Jagnandan. Most researchers initially assumed this posture was a response to a suddenly shifted center of mass. But when Jagnandan observed leopard geckos with a tail in his laboratory, he realized that they wag it as they walk, suggesting that these movements may be key to the lizards' movements.

To test this assumption, Jagnandan and his team assessed the postures of 10 geckos walking in various conditions: with their tail intact （完整的）；with their tail restricted by a small section of glued-on fishing rod （whose mass can be neglected）; and with their tail self-amputated. These comparisons allowed the researchers to distinguish the effects of lost mass from those of lost tail-wagging on the geckos’ movements.

The lizards with an immobilized tail adopted ways similar to those with no tail, the researchers reported in a study published in Scientific Reports. This result suggests the sprawling walk they adopt after losing their tail is not compensating for the missing mass but rather for the lack of tail-wagging. Jagnandan thinks tail movements help the lizards keep balance and stability as they walk. He suspects that the tails of mammals living in trees, such as cats and monkeys, serve a similar purpose.

Bill Ryerson, a biologist at Saint Anselm College, who was not involved in the study, was surprised by the findings. "We thought we had settled it ——it seemed pretty open-and-shut" that mass was the main factor, he says. The new study challenges this earlier idea in a "beautifully simple" way, Ryerson adds.

Jagnandan hopes that understanding how animals react to missing body parts could ultimately help engineers design robots that can move more efficiently as heavy loads — or even entire limbs --- are added and removed.

After twenty years of shaving（剃须）himself every morning, a man in a small Southern town thought he had enough. He told his wife that he intended to let the local barber shave him each day. He put on his hat and coat and went to the barber shop.

The barber's wife, Grace, was working that day, so she performed the task. Grace shaved him, and said, "That will be $20." The man thought the price was a bit high, but he paid the bill and went to work.

The next morning the man looked in the mirror, and his face was as smooth as it had been when he left the barber shop the day before. “Not bad, he thought. At least I don't need to get a shave every day.”

The next morning, the man's face was still smooth. Two weeks later, the man was still unable to find any trace of whiskers on his face. It was more than he could take and he was frightened, so he returned to the barber shop.

"I thought $20 was high for a shave", he told the barber's wife, "but you must have done a great job. It's been two weeks and my whiskers still haven't started growing back."

Foxes and farmers have never got on well. These small dog-like animals have long been accused of killing farm animals. They are officially classified as harmful and farmers try to keep their numbers down by shooting or poisoning them.

Famers can also call on the services of their local hunt to control the fox population. Hunting consists of running after a fox across the countryside, with a group of specially trained dogs, followed by men and women riding horses. When the dogs eventually catch the fox, the kill it or a hunter shoots it.

People who take part in hunting think of it as a sport. They wear a special uniform of red coats and white trousers, and follow strict rules of behavior. But owning a horse and hunting regularly are expensive, so most hunters are wealthy.

It is estimated that up to 100,000 people watch or take part in fox-hunting. But over the last couple of decades the number of people who are against fox-hunting, because they think it is　 brutal(残暴的), has risen sharply. Nowadays it is rare for a hunt to pass off without some kind of conflict between hunters and hunt opponents (阻止者). Sometimes these incidents lead to violence, but mostly opponents discourage the hunt by misleading riders and disturbing the trail of the fox's smell, which the dogs follow.

Noisy conflicts between hunters and opponents have become so common that they are almost as much a part of hunting as running after foxes itself. But this year supporters of fox-hunting face a much bigger threat to their sport. A Labour Party member of Parliament(英国议会), Mike Foster, is trying to get Parliament to approve a new law which will make the hunting of wild　 animals with dogs illegal. If the law is passed, wild animals like foxes will be protected under the ban in Britain.

1.Wealthy people in Britain have been hunting foxes to ______.

A. benefit the farmers　　 B. get entertainment

C. show off their wealth　 D. limit the fox population

2.The opponents of fox-hunting often discourage the game by ______.

A. using violence

B. taking legal action

C. seeking help from farmers

D. confusing the fox hunters

3.A new law may be passed by the British Parliament to ______.

A. protect wild animals like foxes

B. control fox-hunting on a large scale

C. prohibit farmers from hunting foxes

D. standardize the behavior of fox-hunting

4.What can be inferred from this passage?

A. Limiting the fox population is unnecessary at all.

B. Killing foxes with poison is not allowed by the law.

C. Hunting foxes with dogs is considered cruel and violent.

D. Fox-hunting causes conflicts between hunters and farmers.
