If you saw another kid ride her bike too fast around a corner and fall down, you might ride your bike more slowly on that turn. Yes, we humans are very sensitive to others' mistakes. And the same is true for other animals. Animals mess up all the time. They might eat poisonous leaves, fall off a tree or let their prey (獵物) slip away. By watching others fail, an animal can avoid making the same mistakes, thus improving its chance of survival.

Scientists suspected that one part of the brain helps animals process information about others' errors. Cells in that part appear to become more active when a person sees someone else making a mistake. But researchers didn't know whether individual cells in this part of the brain play different roles in detecting errors.

To investigate the brain's response to errors in more detail, the researchers taught a game to two macaques, a type of monkey. One monkey could press a yellow or green button while the other watched. If the first monkey pressed the right button, the team gave both animals a treat. Every couple of rounds, the two monkeys switched roles. Meanwhile, the scientists monitored individual cells in the animal's brains.

When the first monkey messed up the game by pressing the wrong button, a group of cells in the second monkey's brain fired. But if the second monkey also made the wrong choice during its turn, some of the cells in that group didn't respond. Those unresponsive cells reacted specifically to mistakes made by others, not to the monkey's own mistakes.

Scientists believe other parts of the brain also might help people process information about another's errors. "You start to think about this other person and see things from his angle. " Ellen de Bruijn, told Science News. She studies the brain at the University of Leiden in the Netherlands.

1. According to Paragraph 1 , animals' ability to learn from others' mistakes ______.

A. used to be ignored by humans

B. ensures that they will never fail

C. is being lost because of humans

D. helps them to survive better

2.The underlined word "detecting" in Paragraph 2 probably means "______".

A. correcting B. making C. sensing D. drawing

3.In the experiment mentioned, those unresponsive cells are only sensitive to ______.

A. the same buttons B. others' mistakes

C. one's own mistakes D. the monkey's brain

Researchers are placing robotic dogs in the homes of lonely old people to determine whether they can improve the quality of life for humans. Alan Beck, an expert in human-animal relationship, and Nancy Edwards, a professor of nursing, are leading the animal-assisted study concerning the influence of robotic dogs on old people's depression, physical activity, and life satisfaction. “No one will argue that an older person is better off being more active, challenged, or stimulated (刺激),” Edwards points out. “The problem is how we promote that, especially for those without friends or help. A robotic dog could be a solution.”

In the study, the robot, called AIBO, is placed for six weeks in the houses of some old people who live alone. Before placing AIBO in the home, researchers will collect baseline data for six weeks. These old people will keep a diary to note their feelings and activities before and after AIBO. Then, the researchers will review the data to determine if it has inspired any changes in the life of its owner.

“I talk to him all the time, and he responds to my voice,” says a seventy-year-old lady. “When I'm watching TV, he'll stay in my arms until he wants down. He has a mind of his own.”

The AIBOs respond to certain orders. The researchers say they have some advantages over live dogs, especially for old people. Often the elderly are disabled and cannot care for an animal by walking it or playing with it. A robotic dog removes exercise and feeding concerns.

“At the beginning, it was believed that no one would relate to the robotic dog because it was metal and not furry,” Beck says. “But it's amazing how quickly we have given up that belief.”

“Hopefully, down the road, these robotic pets could become a more valuable health helper. They will record their masters’ blood pressure, oxygen levels, or heart rhythms. AIBOs may even one day have games that can help stimulate older people's minds.”

1.The purpose of Beck and Edwards’ study is to ____.

A. understand human-animal relationship

B. find the causes of old people’s loneliness

C. make lonely old people’s life better

D. promote the animal-assisted research

2.In the research, the old people are asked to ____.

A. note the activities of AIBOs

B. keep AIBOs at home for 12 weeks

C. analyze the collected information

D. record their feelings and activities

3.What is the advantage of AIBO over live dogs?

A. It can watch TV with its owner.

B. It can help the disabled people.

C. It responds to all the human orders.

D. It is easier to keep at home.

4.The author seems to suggest that the future robotic dogs may ____.

A. keep old people active B. cure certain diseases

C. change people's beliefs D. look more like real dogs

There are many commonly held beliefs about eye glasses and eyesight that are not proven facts. For instance, some people believe that wearing glasses too soon weakens the eyes. But there is no evidence to show that the structure of eyes is changed by wearing glasses at a young age. Wearing the wrong glasses, however, can prove harmful. Studies show that for adults there is no danger, but children can develop loss of vision if they have glasses inappropriate for their eyes.

We have all heard some of the common myths about how eyesight gets bad. Most people believe that reading in dim light causes poor eyesight, but that is untrue. Too little light makes the eyes work harder, so they do get tired and strained. Eyestrain also results from reading a lot, reading in bed, and watching too much television. However, although eyestrain may cause some pain or headaches, it does not permanently damage eyesight.

Another myth about eyes is that they can be replaced, or transferred from one person to another. They are close to one million nerve fibers(纖維) that connect the eyeball to the brain, so it is impossible to attach them all in a new person. Only certain parts of the eye can be replaced. But if we keep clearing up the myths and learning more about the eyes, some day a full transplant may be possible.

1.If a child wears appropriate glasses, _______.

A. the structure of his eyes will keep the same as before

B. it is harmful

C. the structure of his eyes will be changed

D. he will lose sight

2.If an adult wears inappropriate glasses, _______.

A. his eyes will be weakened

B. he will suffer a lot from the loss of vision

C. it will make no difference to his eyes

D. the structure of his eyes will be changed

3.With the technology we now have, doctors_____.

A. can transfer certain parts of the eye in a new person

B. can transplant the whole eye in a new person

C. still can’t do eye transplant even certain parts of the eye

D. know almost nothing about eyes

4.The author of the passage tends to _______.

A. explain wearing glasses is no harm to children

B. correct people’s wrong beliefs about eyes

C. explain the importance of protecting our eyes

D. imagine what doctors can do with the eye in the future
