The German shepherd runs off and noses around in the grass of Kenya’s Laikipia Plateau. “OK, Oakley,” the dog’s handler orders, “Find it!”
Oakley sniffs (嗅) until he comes to a bush, then stops, sits, and looks up at his handler. She bends to see what he has found: the waste of an endangered African wild dog. “Good dog!” she praises. The handler pulls a tennis ball from her pocket. Oakley jumps for his reward.
“He doesn’t actually want the waste,” says Aimee Hurt, a founding member of the U.S.-based group Working Dogs for Conservation. Hurt is in Kenya to train both Oakley and his handler. “He finds it so he can play with his ball. We’re the ones who want the waste.”
Detection dogs are sometimes taught to locate actual animals. Black-footed ferrets (雪貂) have been studied with their help. But more often the dogs learn to locate the waste of creatures such as bears, wolves and mountain lions.
What the dogs find provides scientists with data about a species. Scientists can use the DNA collected from animal waste to identify individuals, sex, and population sizes — all without ever seeing the animal itself. “It can take years to gather this kind of information if you have to trap animals,” Hurt explains.
Waste analysis might make a huge difference when wild species are accused of attacking domestic livestock (家畜). Hurt says, “A good detection dog will find the waste so we can see what the animal is actually eating.” This may help reduce problems between people and wildlife.
The underlined word “She” in Paragraph 2 refers to “_____”.
A. the German shepherd
B. an African wild dog
C. Aimee Hurt
D. the handler
Oakley is interested in finding the waste because _____.
A. he wants to study endangered animals
B. he can get a tennis ball to play with
C. he wants to eat it
D. he wants to play with it
Which of the following is TRUE according to the passage?
A. Trapping animals is not difficult.
B. People are making efforts to protect the environment.
C. Detection dogs attack domestic livestock frequently.
D. Collecting animal waste is a good way to gather information.
What is the main idea of the passage?
A. Detection dogs can help scientists study wildlife.
B. Detection dogs can defend wildlife.
C. Detection dogs can help the police catch the criminals.
D. Detection dogs can help local people defend domestic livestock.
查看习题详情和答案>>If you are in a town in a western country, you'll often see people walking with their dogs. It is still true that a dog is the most useful animal in the world. But the reason why one keeps a dog has changed Once upon a time, a man met a dog and wanted it to help him in the fight against other animals, and he found that the dog listened to him and did what he told him to. Later people used dogs for the hunting other animals, and the dogs didn't eat what they got until their master agreed. So dogs were used for driving sheep and guarding chicks. But now the people in the towns and cities do not need dogs to fight other animals. Of course they keep them to frighten thieves, but the most important reason is that people feel lonely in the city. For a child, a dog is his best friend when he has no friends to play with. For a young wife, a dog is her child when she doesn’t have her own. For old people, a dog is also a child when their real children have grown up and left. Now people do not have to use a dog, but they keep it as a friend, just like a member of the family.
【小题1】_______are more useful than a dog in the world.
A.No other animals | B.Some animals | C.Many animals | D.A few animals |
A.could fight against other animals | B.met the people |
C.did not eat other animals | D.helped and listened to people |
A.fight other animals | B.are lonely |
C.are like their friends | D.are afraid of the thieves |
A.a child's friend only | B.a young woman's son |
C.old people's real child | D.everybody's friend |
A.always be used | B.not be useful |
C.still fight | D.always be a good friend |
Dogs have an understanding of fair play and become angry if they feel that another dog is getting a better deal, a new study has found.
The study looked at how dogs react when a companion is rewarded for the same trick in an unequal way. Friederike Range, a researcher at the University of Vienna in Austria, and her colleagues did a series of experiments with dogs who knew how to respond to the command “give the paw “. The dogs were normally happy to repeatedly give the paw, whether they got a reward or not. But that changed if they saw that another dog was being rewarded with a piece of food, while they received nothing.
“We found that the dogs hesitated significantly longer when obeying the command to give the paw,” the researchers write. The unrewarded dogs eventually stopped cooperating.
Scientists have long known that humans pay close attention to inequity. But researchers always assumed that animals didn’t share the trait. “The argument was that this is a uniquely human phenomenon,” says Frans de Waal, a professor of psychology at Emory University in Atlanta.
That changed in 2003 when he and a colleague did a study on monkeys. The monkeys had to hand a small rock to researchers to get a piece of cucumber in return. They were happy to do this. But if they saw that another monkey was getting a more delicious reward, a grape, for doing the same job, they would throw away the food and rock, and at some point just stopped performing.
In that experiment, the monkeys considered the fairness of two different types of payment. But when Range and her colleagues did a similar study with their trained dogs, testing to see if dogs would become upset if they only got dark bread when other dogs received sausage, they found that as long as the dogs got some kind of food payment, even if it wasn’t the most delicious kind, the animals would play along.
How did the dogs in Range’s study react to the order of “giving the paw”?
A. They took the order even without being rewarded.
B. They took the order only when rewarded.
C. They turned a deaf ear to repeated orders.
D. They hesitated longer when given repeated orders.
The research by Frans De Waal in 2003 ___________.
A. originated from Range’s research on dogs.
B. showed that animals do pay attention to inequity.
C. began the argument that only humans are aware of inequity.
D. was conducted to find out how monkeys reacted to humans’ orders.
Some monkeys in the research become angry because they found another monkey _______.
A. was given less work.
B. was given more food.
C. was given the same type of food.
D. was given more delicious food.
Range found that, compared with monkeys, dogs ____________.
A. care more about whether they are rewarded.
B. care less about what they are rewarded with.
C. care more about what they are ordered to do.
D. care less about who gives them orders.
What is the main idea of the passage?
A. Animals have various ways to show their anger.
B. Dogs are less intelligent than monkeys.
C. Dogs have a sense of fairness.
D. Most animals want to be rewarded equally.

Fermat’s Last Theorem
Simon Singh
In 1963 a schoolboy called Andrew Wiles reading in his school library came across the world’s greatest mathematical problem: Fermat’s Last Theorem (定理). First put forward by the French mathematician Pierre de Fermat in the seven teenth century, the theorem had baffled and beaten the finest mathematical minds, including a French woman scientist who made a major advance in working out the problem, and who had to dress like a man in order to be able to study at the Ecole Polytechnique. Through unbelievable determination Andrew Wiles finally worked out the problem in 1955. An unusual story of human effort over three centuries, Fermat’s Last Theorem will delight specialists and general readers a like.
