【题目】Muzak
The next time you go into a bank, a store, or a supermarket, stop and listen. What do you hear? 【1】 It's similar to the music you listen to, but it's not exactly the same. That's because this music was especially designed to relax you, or to give you extra energy. Sometimes you don't even realize the music is playing, but you react to the music anyway.
Quiet background music used to be called "elevator(电梯）music" because we often heard it in elevators. But lately we hear it in more and more places, and it has a new name " Muzak". About one-third of the people in America listen to" Muzak" every day. The music plays for 15 minutes at a time, with short pauses in between. It is always more lively between ten and eleven in the morning, and between three and four in the afternoon, when people are more tired. 【2】
If you listen to Muzak carefully, you will probably recognize the names of many of the songs. Some musicians or songwriters don't want their songs to be used as Muzak, but others are happy when their songs are chosen. Why? 【3】
Music is often played in public places because it is designed to make people feel less lonely when they are in an airport or a hotel. It has been proven that Muzak does what it is designed to do. Tired office workers suddenly have more energy when they hear the pleasant sound of Muzak in the background. 【4】 Supermarket shoppers buy 38 percent more groceries.
【5】 They say it's boring to hear the same songs all the time. But other people enjoy hearing Muzak in public places. They say it helps them relax and feel calm. One way or another, Muzak affects everyone. Some farmers even say their cows give more milk when they hear Muzak ！
A. Some people don't like Muzak.
B. The music gives them extra energy.
C. Music is playing in the background.
D. Factory workers produce 13 percent more.
E. Muzak tends to help people understand music better.
F. They get as much as $4 million a year if their songs are used.

【题目】You may have seen a talking parrot on a TV show, in a movie, or even in someone’s home. The parrot has learned to copy sounds that people make. Birds are not the only animals that can copy the noises they hear. Dolphins, bats, and some apes also copy sounds. Now we can add elephants to this list of copycats.
Dr. Joyce Poole is a zoologist. She studies the sounds of elephants. While she was in Kenya, she would hear strange noises made by Mlaika after sunset. Mlaika was a 10-year-old African elephant.
Mlaika lived near a highway. Dr. Poole says, “I could not tell the difference between Mlaika’s call and the distant truck noise.” She and other scientists studied Mlaika’s sounds. It turned out that Mlaika was copying the sounds of the trucks driving by. Why would Mlaika copy trucks that she heard going by on the highway? Animals that are able to copy sounds may enjoy practicing new sounds. When they are kept outside of their natural environment, they may copy unusual sounds. That may be why an elephant would copy the sound of a truck.
“Mlaika was not the only copycat elephant,” Dr. Poole says. Calimero is a 23-year-old male African elephant. He spent 18 years with two female Asian elephants. Asian elephants make chirping sounds (sounds made by birds) to talk with one another. African elephants usually do not make chirping sounds. But Calimero now does. He is copying his Asian elephant friends. Dr. Poole says that elephants need to form bonds with their family and friends. She says, “They make sounds to communicate with each other. When they are separated, they use sounds to keep in contact.”
Parrots, dolphins, humans, and elephants show that being a copycat is one way that animals and people make new friends and keep old ones.
【1】According to the passage, what does Mlaika copy?
A. The sound of people. B. The sound of trucks.
C. The sound of Calimero. D. The sound of birds.
【2】Why is Calimero mentioned in the passage?
A. To clarify the meaning of copycat elephants.
B. To show the cleverness of African elephants.
C. To add another example of copycat elephants.
D. To introduce a special life skill of Asian elephants.
【3】From paragraph 4, we can know ________.
A. how long it takes for an elephant to learn a new sound
B. why the African elephant can make chirping sounds
C. why the Asian elephants make noises after sunset
D. how Asian and African elephants are alike
【4】According to the passage, why do some animals like to be copycats?
A. To keep in touch with nature.
B. To please people and other animals.
C. To make new friends and keep old ones.
D. To avoid the danger from the outside world.
