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．

Imagine you’re at a party full of strangers. You’re nervous. Who are these people? How do you start a conversation? Fortunately, you’ve get a thing that sends out energy at tiny chips in everyone’s name tag (标签). The chips send back name, job, hobbies, and the time available for meeting – whatever. Making new friends becomes simple.

This hasn’t quite happened in real life. But the world is already experiencing a revolution using RFID technology.

An RFID tag with a tiny chip can be fixed in a product, under your pet’s skin, even under your own skin. Passive RFID tags have no energy source – batteries because they do not need it. The energy comes from the reader, a scanning device (装置), that sends out energy (for example, radio waves) that starts up the tag immediately.

Such a tag carries information specific to that object, and the data can be updated. Already, RFID technology is used for recognizing each car or truck on the road and it might appear in your passport. Doctors can put a tiny chip under the skin that will help locate and obtain a patient’s medical records. At a nightclub in Paris or in New York the same chip gets you into the VIP (very important person ) section and pays for the bill with the wave of an arm.

Take a step back: 10 or 12 years ago, you would have heard about the coming age of computing. One example always seemed to surface: Your refrigerator would know when you needed to buy more milk. The concept was that computer chips could he put everywhere and send information in smart network that would make ordinary life simpler.

RFID tags are a small part of this phenomenon. “The world is going to be a loosely coupled set of individual small devices, connected wirelessly.” Predicts Dr. J. Reich. Human right supporters are nervous about the possibilities of such technology. It goes too far tracking school kids through RFID tags, they say. We imagine a world in which a beer company could find out not only when you bought a beer but also when you drank it. And how many beers, accompanied by how many biscuits.

When Marconi invented radio, he thought it would be used for ship – to – shore communication, not for pop music. Who knows how RFID and related technologies will be used in the future. Here’s a wild guess: Not for buying milk.

The article is intended to             .

       A．warn people of the possible risks in adopting RFID technology

       B．explain the benefits brought about by RFID technology

       C．convince people of the uses of RFID technology

       D．predict the applications of RFID technology

We know from the passage that with the help of RFID tags, people          .

       A．will have no trouble getting information about others

       B．will have more energy for conversation

       C．will have more time to make friends

       D．won’t feel shy at parties any longer

Passive RFID tags chiefly consist of           .

       A．scanning devices    B．radio waves    C．batteries    D．chips

The last paragraph implies that RFID technology           .

       A．will not be used for such matters as buying milk

       B．will be widely used, including for buying milk

       C．will be limited to communication uses

       D．will probably be used for pop music

Howling(吼叫) is a behavior commonly observed among a wolf pack(狼群). As pack animals, wolves work together to hunt and rely on howling as an important means of communication among each other. There’re different explanations of a wolf’s howl and it appears that there may be more to discover．
One theory is that wolves howl to bond better together. It’s almost as if howling together helps the pack stay together. Perhaps something similar to people feeling a sense of involvement with each other when singing a song together. But this theory may be wrong, explains Fred H. Harrington, a professor who studies wolf behavior.
Indeed, there have been times when wolves have been seen one moment howling in a chorus(合唱), and the next, quarreling among each other. It appears that usually the lowest-ranking members of the pack may actually be “punished” for joining in the chorus at times. So is howling a way to strengthen a social bond or just a way to reconfirm status (地位) among its members? Why do wolves howl for sure?
What is clear, however, is that howling is often used among pack mates to locate each other. Hunting grounds are distant and it happens that wolves may separate from one another at times. When this happens, howling appears to be an excellent means of gathering.
Howling, interestingly, is a contagious behavior. When one wolf starts to howl, very likely others will follow. This is often seen to occur in the morning, as if wolves were doing some sort of “roll call” where wolves all howl together to report their
【小题1】What is the possible similarity between wolves’ howling together and human’s singing in chorus?

D
While waiting to pick up a friend at the airport in Portland, Oregon, I had an experience which occurred merely two feet away from me.
Trying to locate my friend among the passengers coming through the jet way, I noticed a man walking toward me carrying two light bags. He stopped right next to me to greet his family.
First he kissed his three children one by one and said, “It’s nice to see you. I missed you so much!” Then he hugged his wife, “I’ve saved the best for last!” giving her the longest, most passionate kiss I ever remember seeing. They stared at each other’s eyes, smiling at one another, while holding both hands. For an instant they reminded me of newlyweds（新婚夫妇）, but I knew by the age of their kids that they couldn’t possibly be.
Full of admiration, I asked, “Wow! How long have you two been married?” “Being together for fourteen years total, married twelve of those.” He replied, without breaking his gaze from his lovely wife’s face. “Well, then, how long have you been away?” I asked. “Two whole days!” “Two days?” I was astonished. By the intensity (热烈) of the greeting, I had assumed he’d been gone for at least several weeks --- if not months. I knew my expression betrayed me, so I turned away my eyes and said quietly, “I hope my marriage is still that passionate after so long!”
The man suddenly stopped smiling and looked me straight in the eye. With forcefulness he told me something that left me a different person. “Don’t hope, friend…decide!” Then he smiled again, shook my hand and said, “God bless!”
With that, he and his family turned and walked away together.
I was still watching that man and his special family walk just out of sight when my friend came up to me and asked, “What are you looking at?” Without hesitation, and with a curious sense of certainty, I replied, “My future!”
