Patients and doctors alike have long believed in the healing (治疗) power of humor．It is claimed that humor not only affects patients’ moods，but can actually help them recover faster.
Several studies seem to support this．Patients in better spirits are known to have higher immune cell counts．Some have even claimed to have healed themselves of serious illnesses by reading comics and watching comedies.
Despite all this，many researchers are not convinced． They point out the fact that many sufferings have been known to disappear naturally，with or without a daily dose of laughter．They also say that while optimism in general does seem to be related to better health，it is hard to tell which comes first.
Humor in times of stress，however，clearly makes us feel better．On one level，it takes our minds off our troubles and relaxes us．On another，it releases powerful endorphins，a chemical produced by your body that reduces pain．
There are cases where the appreciation of a good joke is indeed directly related to a person’s health．It can show，for example，whether a person has suffered damage to one particular area of the brain: the right frontal lobe (额叶)．
Scientists confirmed this by having people read jokes and asking them to choose the funniest endings from a list．Subjects with normal brains usually chose endings that were based on a relatively complex synthesis (综合) of ideas．Subjects with specifically located brain damage，however，responded only to slapstick (闹剧) endings，which did not depend on a particular context．When pressed，the brain-damaged subjects saw the logic in the correct endings．They simply did not find them funny.
Of course，humor is largely an individual matter．Next time your friend does not get one of your jokes，there is no need to accuse him of being a lamebrain．However，you might suggest that he lighten up—for the health of it．We can infer from the passage that ________.
| A．all researchers have agreed on the healing power of humor |
| B．people seldom accuse their friends of not understanding jokes |
| C．the author holds a positive attitude to the healing power of humor |
| D．reading comics will surely become a popular way of treating diseases |

How fit are your teeth? Are you lazy about brushing them? Never fear: An inventor is on the case. An electric toothbrush senses how long and how well you brush, and it lets you track your performance on your phone.
The Kolibree toothbrush was exhibited at the International Consumer Electronics Show in Las Vegas this week. It senses how it is moved and can send the information to an Android phone or iPhone via a Bluetooth wireless connection.
The toothbrush will be able to teach you to brush right (don’t forget the insides of the teeth!) and make sure you’re brushing long enough. “It’s kind of like having a dentist actually watch your brushing on a day-to-day basis,” says Thomas Serval, the French inventor.
The toothbrush will also be able to talk to other applications on your phone, so developers could, for instance, create a game controlled by your toothbrush. You could score points for beating monsters among your teeth. “We try to make it smart but also fun,” Several says.
Serval says he was inspired by his experience as a father. He would come home from work and ask his kids if they had brushed their teeth. They said “yes,” but Serval would find their toothbrush heads dry. He decided he needed a brush that really told him how well his children brushed.
The company says the Kolibree will go on sale this summer, for $99 to $199, developing on features. The U.S. is the first target market.
Serval says that one day, it’ll be possible to replace the brush on the handle with a brushing unit that also has a camera. The camera can even examine holes in your teeth while you brush. Which is one of the feature of the Kolibree toothbrush?
| A．It can sense how users brush their teeth. |
| B．It can track users’school performance. |
| C．It can detect users’fear of seeing a dentist. |

Elizabeth Freeman was born about 1742 to African American parents who were slaves. At the age of six months she was acquired, along with her sister, by John Ashley, a wealthy Massachusetts slaveholders. She became known as “Mumbet” or “Mum Bett.”
For nearly 30 years Mumbet served the Ashley family. One day, Ashley’s wife tried to strike Mumbet’s sister with a spade. Mumbet protected her sister and took the blow instead. Furious, she left the house and refused to come back. When the Ashleys tried to make her return, Mumbet consulted a lawyer, Theodore Sedgewick. With his help, Mumbet sued(起诉) for her freedom.
While serving the Ashleys, Mumbet had listened to many discussions of the new Massachusetts constitution. If the constitution said that all people were free and equal, then she thought it should apply to her. Eventually, Mumbet won her freedom---- the first slave in Massachusetts to do so under the new constitution.
Strangely enough, after the trial, the Ashleys asked Mumbet to come back and work for them as a paid employee. She declined and instead went to work for Segdewick. Mumbet died in 1829, but her legacy lived on in her many descendants(后裔). One of her great-grandchildren was W.E.B. Du Bois, one of the founder of the NAACP, and an important writer and spokesperson for African American civil rights.
Mumbet’s tombstone still stands in the Massachusetts cemetery where she was buried. It reads, in part: “She was born a slave and remained a slave and remained a slave for nearly thirty years. She could neither read nor write, yet in her own sphere she had no superior or equal.”What do we know about Mumbet according to Paragraph 1?
| A．She was born a slave |
| B．She was a slaveholder |
| C．She had a famous sister |

Why did Mumbet run away from the Ashleys?
| A．She found an employer |
| B．She wanted to be a lawyer |
| C．She was hit and got angry |

What did Mumbet learn from discussions about the new consititution?
| A．She should always obey her owners’ orders |
| B．She should be as free and equal as whites |
| C．How to be a good servant |
| D．How to apply for a job |
What did Mumbet do after the trial?
| A．She chose to work for a lawyer |
| B．She found the NAACP |
| C．She continued to serve the Ashleys |
| D．She went to live with her grandchildren |
Running like the wind, roaring (咆哮) like thunder, tigers have long been feared and respected as a king of the animal world. But last week a report said that there are no more than 30 wild tigers left in south China.
This was the conclusion of a team of scientists from China's State Forestry Administration and the World Nature Fund.
The South China tiger, also known as the Chinese tiger, is native to southern China. In the 1950's, there were over 4000 tigers found in mountain forests in the country. But due to the destruction of their natural habitat and uncontrolled hunting, it has been pushed on to the list of the world's top ten most endangered species.
Sixtysix of the big cats can be found in the cages of a dozen zoos around China. But they are nothing like their wild cousins. They have lost their natural skills such as hunting and killing. If they were set free they could not look after themselves.
“Breeding has damaged the quality of the species”， said Pei Enle, deputy director of the Shanghai Zoo.
To reintroduce the species into the wild, the country started a programme to send five to ten young tigers to South Africa. Four of them have already arrived. Progress has been made as two elder tigers have recovered some of their instincts(本能) and can hunt wild animals by themselves at the African base.
“South Africans are very experienced in reintroducing big animals to the wild. The country has very good natural conditions for the tigers to learn in”， said Lu Jun, office director of the National Wildlife Research and Development Center. “We tried in Fujian Province, but it was not successful as there was not a complete ecochain(生物链) and there was a lack of space.”
The tigers should return to China in 2007 when the reservations in Fujian are ready.What is the main reason for the South China tiger becoming one of the world's top ten most endangered species?
| A．Because it has lost its natural instincts. |
| B．Because there is not a complete ecochain. |
| C．Because there is no space for it. |
| D．Because uncontrolled hunting has destroyed its natural living conditions. |
How is the programme of sending several tigers to South Africa getting on?
| A．Its effect still remains to be seen. |
| B．Two tigers can already compete with their wild cousins. |
| C．Some of the tigers are already on the road to recovering their natural skills. |
| D．The tigers should be able to recover their instincts completely by 2007. |
By saying “but they are nothing like their wild cousins”， the writer means that________.
| A．they are no longer feared by other wild animals |
| B．they don't know how to hunt or kill |
| C．a complete change has resulted in the species because of breeding |
| D．to reintroduce them into the wild has become an urgent task |
What is the purpose of sending young tigers to South Africa?
| A．To help the tigers recover their ability to live in the wild. |
| B．To provide them with a better environment. |
| C．To get the tigers to go on a tour. |
| D．To find a complete ecochain for them. |
Which one is NOT the reason for South Africa being chosen as the training place?
| A．Because the tigers can hunt wild animals by themselves at the African base. |
| B．Because South Africans are skilled at dealing with the tigers. |
| C．Because there is a complete ecochain and enough space there. |
| D．Because the country has good natural conditions for the tigers to learn in. |
Since the 1970s, scientists have been searching for ways to link the brain with computers. Braincomputer interface (BCI) technology could help people with disabilities send commands to machines.
Recently, two researchers, Jose Millan and Michele Tavella from the Federal Polytechnic School in Lausanne, Switzerland, demonstrated (展示) a small robotic wheelchair directed by a person's thoughts.
In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand. He could even talk as he watched the vehicle and guided it with his thoughts.
“Our brain has billions of nerve cells. These send signals through the spinal cord (脊髓) to the muscles to give us the ability to move. But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles.” Tavella says. “Our system allows disabled people to communicate with external world and also to control devices.”
The researchers designed a special cap for the user. This head cover picks up the signals from the scalp (头皮) and sends them to a computer. The computer interprets the signals and commands the motorized wheelchair. The wheelchair also has two cameras that identify objects in its path. They help the computer react to commands from the brain.
Prof. Millan, the team leader, says scientists keep improving the computer software that interprets brain signals and turns them into simple commands. “The practical possibilities that BCI technology offers to disabled people can be grouped in two categories: communication, and controlling devices. One example is this wheelchair.”
He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology they can benefit from. And the other is to guarantee that they can use the technology over long periods of time.BCI is a technology that can ________.
| A．help to update computer systems |
| B．link the human brain with computers |
| C．help the disabled to recover |
| D．control a person's thoughts |
How did Tavella operate the wheelchair in the laboratory?
| A．By controlling his muscles. |
| B．By talking to the machine. |
| C．By moving his hand. |
| D．By using his mind. |
Which of the following shows the path of the signals described in Paragraph 5?
| A．scalp→computer→cap→wheelchair |
| B．computer→cap→scalp→wheelchair |
| C．scalp→cap→computer→wheelchair |
| D．cap→computer→scalp→wheelchair |
The team will test with real patients to ________.
| A．make profits from them |
| B．prove the technology useful to them |
| C．make them live longer |
| D．learn about their physical condition |
Which of the following would be the best title for the text?
| A．Switzerland, the BCI Research Center |
| B．New Findings About How the Human Brain Works |
| C．BCI Could Mean More Freedom for the Disabled |
