They may be small and not able to speak, but babies are proving their amazing cleverness. Scientists began finding infants’ skills are more than they are supposed to be.
_________
Speaking of music, babies can’t seem to resist it. Not only are their ears turned to the beats, babies can actually dance to the music.
To test babies’ dancing ability, the researchers played recordings of classical music, rhythmic beats and speech to infants, and recorded the results. They also invited professional dancers to analyze how well the babies matched their movements to the music. The babies moved their arms, hands, legs feet and heads in response to the music, much more than to the speech. The finding suggests this dancing ability is innate(与生俱来的) in humans, though the researchers aren’t sure why it becomes weaker later in their life.
Learning Quickly while Sleeping
Babies can learn even while asleep, according to a 2011 study. In experiments with 26 sleeping infants, each just 1 to 2 days old, scientists played a musical tone followed by a puff of air to their eyes 200 times over the course of a half-hour. 124 electrodes(电极) stuck on the head and face of each baby recorded brain activity during the experiments. The babies rapidly learned to foretell a puff of air upon hearing the tone, showing a four-time increase on average in the chances of tightening their eyelids in response to the sound by the end of the experiments.
As newborns spend most of their time asleep, this newfound ability might be crucial to rapidly adapting to the world around them and help to ensure their survival, researchers said.
Judging Characters Well
Judging another person helpful or harmful is crucial when choosing friends. And that ability starts early. Kiley Hamlin of Yale University showed both 6-and 10-month-olds a puppet(木偶) show, in which one character helped another climb a hill. In another scene a third character pushed the climber down. The little ones then got to choose which character they preferred. For both age groups, most babies chose the helper character. This character-judging ability could be baby’s first step in the formation of morals, Hamlin thought.Which of the following subtitles can fill in the underlined blank?

Dear Hamilton,
We are fortunate that in such a large, high-pressure office we all get along so well. You are one of the people who keep the social temperature at such a comfortable setting. I don’t know anyone in the office who is better liked than you.
You can perhaps help with this. The collection of contributions towards gifts for employees’ personal-life events is becoming a little troubling. Certainly, the group sending of a gift is reasonable now and then. In the past month, however, there have been collections for two baby shower gifts, one wedding shower gift, two wedding gifts, one funeral(葬礼)remembrance, four birthday gifts, and three graduation gifts.
It’s not only the collected-from who are growing uncomfortable (and poor), but the collected-for feel uneasy receiving gifts from people who don’t know them outside the office, who wouldn’t even recognize their graduating children, their marrying daughters and sons, or their dead relatives.
This is basically a kind gesture (and one that people think well of you for), but the practice seems to have become too wide-ranging and feels improper in today’s office setting.
Thank you for understanding.The underlined word “contributions” probably means ________.
A.money | B.suggestions | C.reports | D.understanding |
Hamilton is expected to _______.
A.show more kindness. | B.discontinue the present practice |
C.quit being the organizer for gift giving | D.know more about co-workers’ families |
This is basically a letter of ________.
A.apology | B.sympathy | C.appreciation | D.dissatisfaction |

Domestic (驯养的) horses now pull ploughs, race in the Kentucky Derby, and carry police. But early horses weren’t tame (驯服的) enough to perform these kinds of tasks. Scientists think the first interactions humans had with horses were far different from those today.
Thousands of years ago, people killed the wild horses that lived around them for food. Over time, people began to catch the animals and raise them. This was the first step in domestication.
As people began to tame and ride horses, they chose to keep those animals that had more desirable characteristics. For example, people may have chosen to keep horses that had a gentle personality so they could be ridden more easily. People who used horses to pull heavy loads would have chosen to keep stronger animals. Characteristics like strength are partly controlled by the animals’ genes. So as the domesticated horses reproduced, they passed the characteristics on to their young. Each new generation of houses would show more of these chosen characteristics.
Modern day horse breeds come in a wide variety of shapes and sizes. This variety didn’t exist in the horse population before domestication. The Shetland horse is one of the smallest breeds—typically reaching only one meter tall. With short, strong legs, the animals were bred to pull coal out of mine shafts (矿井) with low ceilings. Huge horses like the Clydesdale came on the scene around 1700. People bred these heavy, tall horses to pull large vehicles used for carrying heavy loads.
The domestication of horses has had great effects on societies. For example, horse were important tools in the advancement of modern agriculture. Using them to pull ploughs and carry heavy loads allowed people to farm more efficiently. Before they were able to ride horses, humans had to cross land on foot. Riding horses allowed people to travel far greater distance in much less time. That encouraged populations living in different areas to interact with one another. The new from of rapid transportation helped cultures spread around the world.Before domestication horses were ______.
A.caught for sports | B.hunted for food |
C.made to pull ploughs | D.used to carry people |

Twenty years ago, I drove a taxi for a living. One night I went to pick up a passenger at 2:30 AM. When I arrived to collect, I found the building was dark except for a single light in a ground floor window.
I walked to the door and knocked, “Just a minute,” answered a weak, elderly voice.
After a long pause, the door opened. A small woman in her eighties stood before me. By her side was a small suitcase.
I took the suitcase to the car, and then returned to help the woman. She took my arm and we walked slowly toward the car.
She kept thanking me for my kindness. “It’s nothing,” I told her. “I just try to treat my passengers the way I would want my mother treated.”
“Oh, you’re such a good man.” She said. When we got into the taxi, she gave me an address, and then asked, “Could you drive through downtown?”
“It’s not the shortest way,” I answered quickly.
“Oh, I’m in no hurry,” she said. “I’m on my way to a hospice(临终医院). I don’t have any family left. The doctor says I don’t have very long.”
I quietly reached over and shut off the meter(计价器).
For the next two hours, we drove through the city. She showed me the building where she had once worked, the neighborhood where she had lived, and the furniture shop that had once been a ballroom where she had gone dancing as a girl.
Sometimes she’d ask me to slow down in front of a particular building and would sit staring into the darkness, saying nothing.
At dawn, she suddenly said,” I’m tired. Let’s go now.”
We drove in silence to the address she had given me.
“How much do I owe you?” she asked.
“Nothing.” I said.
“You have to make a living,” she answered. “Oh, there are other passengers,” I answered.
Almost without thinking, I bent and gave her a hug. She held onto e tightly. Our hug ended with her remark, “You gave an old woman a little moment of joy.”The old woman chose to ride through the city in order to ______.
A.show she was familiar with the city | B.see some places for the last time |
C.let the driver earn more money | D.reach the destination on time |
The taxi driver did not charge the old woman because he ______.
A.wanted to do her a favor | B.shut off the meter by mistake |
C.had received her payment in advance | D.was in a hurry to take other passengers |
What can we learn from the story?
A.Giving is always a pleasure. | B.People should respect each other. |
C.An act of kindness can bring people great joy. | |
D.People should learn to appreciate others’ concern. |
Thirteen vehicles lined up last March to race across the Mojave Desert, seeking a million in prize money. To win, they had to finish the 142-mile race in less than 10 hours. Teams and watchers knew there might be no winner at all, because these vehicles were missing a key part -drivers.
DARPA, the Defense Advanced Research Projects Agency, organized the race as part of a push to develop robotic vehicles for future battlefields. But the Grand Challenge, as it was called, just proved how difficult it is to get a car to speed across an unfamiliar desert without human guidance. One had its brake lock up in the starting area. Another began by throwing itself onto a wall. Another got tied up by bushes near the road after 1.9 miles.
One turned upside down. One took off in entirely the wrong direction and had to be disabled by remote (远距离的) control. One went a little more than a mile and rushed into a fence; another managed to go for six miles but stuck on a rock. The “winner,” if there was any, reached 7.8 miles before it ran into a long, narrow hole, and the front wheels caught on fire.
“You get a lot of respect for natural abilities of the living things,” says Reinhold Behringer, who helped design two of the car-size vehicles for a company called Sci-Autonics. “Even ants (蚂蚁) can do all these tasks effortlessly . It’s very hard for us to put these abilities into our machines.”
The robotic vehicles, though with necessary modern equipment such as advanced computers and GPS guidance, had trouble figuring out fast enough the blocks ahead that a two-year-old human recognizes immediately, Sure, that very young child, who has just only learned to walk, may not think to wipe apple juice off her face, but she already knows that when there’s a cookie in the kitchen she has to climb up the table, and that when she gets to the cookie it will taste good. She is more advanced, even months old, than any machine humans have designed.Watchers doubted if any of the vehicles could finish the race because .
A.they did not have any human guidance |
B.the road was not familiar to the drivers |
C.the distance was too long for the vehicles |
D.the prize money was unattractive to the drivers |
DARPA organized the race in order to .
A.raise money for producing more robotic vehicles |
B.push the development of vehicle industry |
C.train more people to drive in the desert |
D.improve the vehicles for future wars |
From the passage we know “robotic vehicles” are a kind of machines that .
A.can do effortlessly whatever tasks living thing can |
B.can take part in a race across 142 miles with a time limit |
C.can show off their ability to turn themselves upside down |
D.can move from place to place without being driven by human beings |
In the race, the greatest distance one robotic vehicle covered was .
A.about eight miles | B.six miles |
C.almost two miles | D.about one mile |
In the last paragraph, the writer implies that there is a long way to go .
A.for a robotic vehicle to finish a 142-mile race without any difficulties |
B.for a little child who has just learned to walk to reach the cookie on the table |
C.for a robotic vehicle to deal with a simple problem that a little child can solve |
D.for a little child to understand the importance of wiping apple juice off its face |
MONTREAL (Reuters) – Crossing the US-Canada border(边界)to go to church on a Sunday cost a US citizen $10,000 for breaking Washington’s strict new security(安全)rules.
The expensive trip to church was a surprise for Richard Albert, who lives right on the Canadian border. Like the other half-dozen people of Township 15, crossing the border is a daily occurrence for Albert. The nearby Quebec village of St. Pamphile is where they shop, eat and go to church.
There are many such situations in these areas along the largely unguarded 5,530-mile border between Canada and the US-which in some cases actually runs down the middle of streets or through buildings.
As a result, Albert says he did not expect any problems three weeks ago when he returned home to the US after attending church in Canada, as usual. The US customs(海关)station in this area is closed on Sundays, so be just drove around the locked gate, as he had done every weekend since the gate appeared last May, following a tightening of border security. Two days later. Albert was told to go to the customs office, where an officer told him be had been caught on carnera crossing the border illegally(非法).
Ottawa has given out special passes to some 300 US citizens in that area so they can enter the country when Canadian customs stations are closed, but the US stopped a similar program last May. That forces the people to a 200-mile detour along hilly roads to get home through another border checkpoint.
Albert has requested that the customs office change their decisions on the fine, but he has not attended a Sunday church since. “I feel like I’m living in a prison,” he said.We learn from the text that Richard Albert is .
A.an American living in Township 15 | B.a Canadian living in a Quebec village |
C.a Canadian working in a customs station | D.an American working in a Canadian church |
Albert was fined because he .
A.failed to obey traffic rules | B.broke the American security rules |
C.worked in St. Pamphile without a pass | D.damaged the gate of the customs office |
The underlined word “detour” in paragraph 5 means .
A.a drive through the town | B.a race across the fields |
C.a roundabout way of travelling | D.a journey in the mountain area |
What would be the best title for the text?
A.A Cross-country Trip | B.A Special Border Pass |
C.An Unguarded Border | D.An Expensive Church Visit |
