Next time you hear a funny joke you’d better not laugh too hard. According to a paper published by the British Medical Journal, laughter isn’t always the best medicine. Sometimes it can even be harmful. Professor Robin Ferner from the University of Birmingham, one of the authors of the study, found that bad things could happen to people who laughed too much. He says: “We found people with heartbeat problems which had stopped their heart, we found people who had fainted(昏倒), and we found people who’d dislocated their jaws or burst their lungs.”

It seems that laughing can be no laughing matter. But it’s not all doom and gloom. Professor Ferner says there are benefits to laughing when you want to lose weight, for example. Yes, that’s right: laugh and be slimmer! Professor Ferner explains that: “You use energy when you laugh, you move your diaphragm(横膈膜), you expand your lungs, and both those things can be helpful.”

According to the research, laughing for a quarter of an hour can burn up to 40 calories, and if you laughed all day you’d use up about 2,000 calories, which is what most people consume in a day. But don’t do that or you might end up with a painful jaw. Ouch! Or you might find people looking at you in a funny way.

But I don’t want to finish this article leaving you feeling desperate. Laughter comes naturally for most of us. Babies begin to laugh at around 3-6 months. So give in to your sense of humor and keep smiling. Life is short anyway.

1.Laughing too much may cause the following harmful results EXCEPT_________.

A. diaphragm movement

B. heart stop

C. lung burst

D. jaw dislocation

A. nervous B. funny

C. painful D. hopeless

3. How many calories can you use if you laugh for half a day?

A. About 40. B. About 2,000.

C. About 1,000. D. About 2,040.

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 (猎物) 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
