Long, long ago there were a lot of donkeys. The donkeys worked hard every day. They had no time to play or to relax, but they never felt appreciated (得到赏识的) for the work they did.

One day two donkeys got bored. They wanted to live a comfortable life, so the donkeys went to see a wise old man. They told him their problem. The wise old man agreed they worked too hard, and he wanted to help the donkeys. “I have an idea,” he said.

“What is your idea?” asked the donkeys.

“I will paint you and no one will know you are donkeys,” said the man.

The man went off to find some paint and he returned in just a matter of minutes. He had two pots of paints. One pot was filled with white paint, and the other black paint.

The old man first painted them white, and then painted stripes(斑纹 ) over the white paint. When he finished, the donkeys did not look like donkeys at all. “You no longer look like donkeys,” the old man said. “Everyone will be fooled (欺骗). I will call you something else, zebras( 斑马).”

The zebras went to a field to eat grass. Now they did not have to work.

Soon, other donkeys saw the zebras. They asked the zebras where they came from. When the zebras told the donkeys their secret, the donkeys all rushed to see the old man.

“Please make us into zebras, too,” they pleaded. So the wise old man painted more donkeys. As he did, more and more donkeys came.

The old man could not paint fast enough. Soon the donkeys became impatient(不耐烦的). They began to kick about, and they knocked over the paint pots.

There was no more paint. The painted donkeys ran off to become zebras. The unpainted donkeys, because of their impatience, had to return to work.

Before birth,babies can tell the difference between loud sounds and voices.They can even distinguish their mother’s voice from that of a female stranger.But when it comes to embryonic learning(胎教),birds could rule the roost.As recently reported in The Auk:Ornithological Advances,some mother birds may teach their young to sing even before they hatch(孵化).New-born chicks can then imitate their mom’s call within a few days of entering the world.

This educational method was first observed in 2012 by Sonia KIeindorfer,a biologist at Flinders University in South Australia,and her colleagues.Female Australian superb fairy wrens were found to repeat one sound over and over again while hatching their eggs,When the eggs were hatched,the baby birds made the similar chirp to their mothers—a sound that served as their regular “feed me!”call.

To find out if the special quality was more widespread in birds,the researchers sought the redbacked fairy wren,another species of Australian songbird.First they collected sound data from 67 nests in four sites in Queensland before and after hatching.Then they identified begging calls by analyzing the order and number of notes.A computer analysis blindly compared calls produced by mothers and chicks,ranking them by similarity.

It turns out that baby red-backed fairy wrens also emerge chirping like their moms. And the more frequently mothers had called to their eggs,the more similar were the babies’ begging calls. In addition,the team set up a separate experiment that suggested that the baby birds that most closely imitated their mom’s voice were rewarded with the most food.

This observation hints that effective embryonic learning could signal neurological(神经系统的)strengths of children to parents.An evolutionary inference can then be drawn.”As a parent,do you invest in quality children,or do you invest in children that are in need?”KIeindorfer asks.”Our results suggest that they might be going for quality.”

B.The observation of fairy wrens across Australia.

C.The data collected from Queensland’s locals.

D.Controlled experiments on wrens and other birds.

3.Embryonic learning helps mother birds to identify the baby birds which .

A.can receive quality signals B.are in need of training

C.fit the environment better D.make the loudest call

Oh my God, the robots are taking over! We’re doomed! Doomed! Now that I’ve gotten that out of my system, it’s become clear that while we may or may not be doomed, the robots are taking over. The latest example is the government’s new guidelines for self-driving cars.

Tesla, Google and Uber are already testing driverless cars in cities across America. Uber chief executive Travis Kalanick is among those predicting that by 2021, self-driving cars will play a big part in urban settings.

Nearly 40,000 people died last year in this nation in automobile-related accidents, and we believes driverless cars can save tens of thousands of lives annually.

Makes sense. Robot drivers are less likely to get drunk, drive without a license, text while driving or feel agitated at the scene of a pileup. On the other hand, I wonder how these highly sensitive cars will react, with walkers constantly dashing into the street. Will they jam on the brakes every 10 seconds?

But there’s a bigger picture. Not only are robots replacing humans behind the wheel, but behind the work desk, in warehouses, senior homes, you name it. Robots aren’t just taking over in the workplace.

The question is, where can’t a robot function better than a human? How about writing songs? A robot can go through every combination of notes in record time and come up with a pleasing melody. The lyrics might be a different story. Is a Grammy-winning song co-written by Hank Human and R-3071 in our future?

Finally, it’s only a matter of time until we have robot politicians and presidential candidates. Why not? They can be programmed to be experts in world and domestic affairs and come up with the best solutions without corruption and bad humors.

Actually, it’s too bad such technology isn’t available in 2016. Pretty sure the robot would win in a landslide.

1.What does the underlined word “agitated” mean?

A. Tired B. Cautious

C. Careful D. Anxious

2.What doubt does the writer have about self-driving cars?

A. How passengers behave in it.

B. How robot drivers get the license.

C. How they avoid crashing into other car.

D. How they respond to walkers on a busy street.

3.The last questions asked in the sixth paragraph reflects the writer’s ________.

A. confidence in robots, winning Grammy Awards

B. eagerness to listen to songs written by robots

C. doubt about robots’ ability to write songs

D. curiosity about the future Grammy songs

4.What might be the most suitable title for the text?

A. Robots will control the world in every field

B. Robots are coming but not soon enough

C. Robots are being used in our daily life

D. Robots can drive cars and write music
