At Englands University of Plymouth, Professor Eduardo Miranda has been programming pairs of robots to compose music. Miranda's robots have simple " vocal cords" (声带)and are programmed to sing and to listen to each other. The robots' unique warbling sounds (颤音) do not perfectly match the human voice, but each machine is exactly sharing music with the other in a new and unique way.

Each robot is equipped with speakers, software that mimics the human voice, a mouth that opens as it "sings," a microphone for ears, and a camera for eyes. The robots also move. Miranda hopes that by studying his robot vocalists, he can discover something about how and why humans create, perform, and listen to music.

When the robots sing, first one robot makes six random sounds. Its partner responds with more sounds. The first robot analyzes the sounds to see if their sequences (序列)) are similar. If they are, it nods its head and commits the sounds to memory, and the second robot notices and "memorizes" the musical sequence, too. If the first robot thinks the sounds are too different, it shakes its head and both robots ignore the sounds. Then the process continues.

Miranda set up an experiment in which he left the two robots alone in his study for two weeks. When he returned, his little warblers had, by imitating each other, not only shared notes but combined them. The product of their cooperation was far from symphonic, but the robots had begun to combine the notes into their own self-developed "songs".

With the help of his warbling robots, one of Miranda's goals is to create music that no human would ever compose. Miranda believes the robots are ideal for this purpose because they would not be influenced by any existing musical styles or rules.

(1)、Which is closest in meaning to the underlined word "mimics" in Paragraph 2?
A、Substitutes. B、Interrupts. C、Controls. D、Copies.
(2)、What did the two robots do during Miranda's experiment?
A、They interacted with each other. B、They ignored the unique sound. C、They learned to sing better than humans. D、They committed random sounds to memory.
(3)、What does Miranda want his robots to do?
A、Sing as well as humans do. B、Create new styles of music. C、Memorize a variety of music. D、Promote traditional musical forms.
(4)、What is the text mainly about?
A、Future robots. B、Special songs. C、Music by robots. D、Experiments by Miranda.

    Early birds-people who feel most energetic in the morning-tend to make healthier food choices throughout the day than night owls(夜猫子) , according to a new study.

    "Evening types had more irregular meal times," notes study author Mirkka Maukonen, studying human nutrition and obesity(肥胖) in Finland.

    Her study focused on people's risk of heart disease and their eating habits. Participants described when and what they had eaten during the past two days.

Maukonen's team then looked at l,854 people's lifestyle. After analyzing the data, the researchers found that both morning and evening people consumed approximately the same number of calories over a whole day.  However, night owls tended to eat their meals later than early birds. Before 10:00 am, night owls consumed less food than early birds. More of their calories came from sugar. After 8:00 pm, the night owls ate more sugar and fat. Meanwhile ,early birds ate more protein during both the morning and the evening hours.

    "Night owls tend to be less healthy than early risers," notes Courtney Peterson who studies diet and meal timing. "They are more likely to get heart disease or cancer. The fact that night owls tend to eat more junk food probably plays a role," Peterson says. "Other factors(因素) also can ruin a night owl's health. Night owls generally sleep worse," says Peterson. "Poor sleep has been linked to unhealthy food choices. "

    Peterson and Maukonen say night owls tend to have poor eating habits. But that doesn't necessarily mean that being a night owl makes a person a poor eater. It could be the reverse- eating poorly could affect people's sleep habits.

"The new findings should serve as a wake-up call to night owls. For them, the new results should encourage paying attention to healthier lifestyle choices," says Maukonen. 28. How did Maukonen do research about people's risk of heart disease?

An Invisible Smile

    Mr Dawson was an old man who always complained a lot, and everyone in town knew it. Kids ever went into his yard to pick a delicious apple. Old Dawson, they said, would come after them with his gun.

    One Friday, 12-year-old Janet was going to stay all night with her friend Amy. They had to walk by Dawson's house on the way to Amy's house, but as they got close, Janet saw him sitting on his front porch and suggested they cross over to the other side of the street. Like most of the children,Janet was scared of the old man.

    Amy said not to worry, Mr Dawson wouldn't hurt anyone. Still, Janet was growing more nervous with each step closer to the old man's house. When they got close enough, Dawson looked up with his usual frown, but when he saw it was Amy, a broad smile changed his entire face as he said, “Hello, Miss Amy. I see you've got a little friend with you today. ”

    Amy smiled back and told him Janet was staying overnight and they were going to listen to music and play games. Mr Dawson said that sounded fun and offered them each a fresh picked apple off his tree. They gladly accepted. Mr Dawson had the best apples in the whole town.

    When they left, Janet asked Amy, “Everyone says he's the meanest man in town. How come he was so nice to us?”

    Amy explained that when she first started walking past his house he wasn't very friendly and she was afraid of him, but she pretended he was wearing an invisible smile and so she always smiled back at him. It took a while, but one day he half-smiled back at her.

    After some more time, he started smiling real smiles and then started talking to her. Just a “hello” at first, then more. She said he always offered her an apple and was always very kind.

    “An invisible smile? ”questioned Janet.

    “Yes,”answered Amy, “my grandma told me that if I pretended I wasn't afraid and pretended he was smiling an invisible smile at me and I smiled back at him, sooner or later he would really smile. Grandma says smiles are contagious.”

If we remember what Amy's grandma said — everyone wears an invisible smile, we too will find that we're always on the go trying to accomplish so much, aren't we? It's so easy to get caught up in everyday life that we forget how simple it can be to bring cheer to ourselves and others. Giving a smile away takes so little effort and time. Let's make sure that we're not the ones that others have to pretend to be wearing an invisible smile.
