     Since the 1970s, scientists have been searching for ways to link the brain with computers. Brain-computer
interface (BCI) technology could help people with disabilities send commands to machines.
     Recently, two researchers, Jose Milan 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 band. 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. Milan, 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.
1. 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
2. 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.
3. 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
4. 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
5. 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
D. Robotic Vehicles Could Help to Cure Brain Injuries

  “Privacy” is translated as“yin si”in Chinese. Traditionally, in the Chinese mind,“yin si”is associated with that which is closed or unfair. If someone is said to have“yin si”, meddlers (好事者) will be attracted to pry(打探)into his or her affairs. So people always state that they don't have“yin si”.

  On the contrary, Americans often declare their intention to protect their privacy. Their understanding of privacy is that others have no right to pry into things which belong to themselves alone and have nothing to do with others. One who is too curious and who spreads rumors is said to violate the right to privacy.

  In the evening, Sonia and I went to a bar for dinner. In China, when people mention bars, something bad usually comes to mind. But here, the bar was a quiet and tastefully laid out place. People spoke quite softly, afraid of interrupting their neighbors, and sat face to face as they drank, sometimes three or five persons sitting together.

  This sort of atmosphere was totally different from my preconception(传统观念), so I wanted to take a picture. Sonia stopped me:“Don't you see these people are pouring out their hearts? Maybe they are colleagues, friends, secret lovers. They came here looking for a peaceful place free from interruption by others. They wouldn't want to leave any trace of their having come here. So taking their pictures would be a serious violation of their right to privacy.”

  Is there privacy between husband and wife? One of Sonia's friends married a talented Chinese man, but recently she became so angry that she wanted a divorce(离婚). The reason was that her husband had opened one of her letters and looked through her purse. The husband didn't realize that this is not tolerated in the U.S. He thought that being a couple was like being one person; why couldn't he see the letter or the contents of the purse? Truly, everyone, even those living as a couple, needs room--not only in three-dimensional(三维) space, but in the heart.

1.What is the main idea of the text?

[  ]

A.The understanding of“privacy”is different in China and America.

B.There is privacy between husband and wife in America.

C.Everyone has the right to privacy.

D.Everyone in every country needs room for himself.

2.Sonia stopped me when I wanted to take a picture in the bar because _____.

[  ]

A.taking pictures in a bar was not allowed in America

B.taking pictures in a bar would interrupt the neighbors

C.people who came here are colleagues,friends or secret lovers

D.taking pictures in a bar would violate other people's right to privacy

3.One of Sonia's friends wanted a divorce because _____.

[  ]

A.she thought her husband was not clever enough

B.her husband always opened her letters

C.her husband always looked through her purse

D.her husband didn't respect her right to privacy

4.Which of the following statements is NOT the Americans' understanding of privacy?

[  ]

A.Privacy is connected with something that is unfair and bad.

B.Other people have no right to pry into his or her affairs.

C.There is privacy even between couples.

D.The right to privacy shouldn't be violated by others.

5.According to this text, we can infer that in America we can do all the following except _____.

[  ]

A.declaring that we have privacy

B.going to a bar with friends

C.asking your friends about their marriage

D.taking pictures in a national park

阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。
A
When I worked in Swaziland, one day we went to an orphanage. There we found a beautiful little girl named Tanzile. I gave her a sweet and she said something back to me in Si-swati, which the nurse next to me translated, “She wants another one — to give to her little sister.” I said “of course”. When we were going to leave, we passed by Tanzile’s house to say goodbye. To our surprise she seemed to be holding on to that extra sweet I had given her. I remember saying to the nurse “this little darling is clever — she has taken two for herself.”
But the nurse told us, “Tanzile is 7 now. Two years ago her mum and dad both died of AIDS. She was separated from her sister who was three at the time. Tanzile has not laid eyes on her since. But from then on whenever Tanzile receives anything from anyone, including food — she refuses to accept it, unless they give her two.” In fact, in the little mud hut where she lives, we find a pile of old things which she has been collecting to give to her sister one day.
People sometimes look at faces of African children and think that they are somehow different from our kids — that somehow they don’t feel pain or love. But that is not true. Their pain is deep. And so is their love. I can still remember the nurse trying to convince her that “if someone gives you food, you must accept it — even if it is only one piece and not two — for your own health.” And it was so hard for us to keep the tears from our eyes as she shook her head. Her hope and her love was all that she had. It mattered more than anything else. When I returned home that day, I was shocked to find that this was not an isolated story but others in the hospital knew of orphans just like Tanzile — waiting with a little pile of things in their hut, for their lovers who they haven’t seen so long.
I think of that old song — “when we’re hungry, love will keep us alive.”
56. From the passage we can learn Tanzile__________.
A. is very clever        B. knows her sister has died
C. has stored a lot for her sister       D. doesn’t like sweets
57. How old was her sister when the author met with Tanzile?
A. Three years old.    B. Four years old.
C. Five years old.     D. Six years old.
58. What has the author learned from her experience in Africa?
A. Love is more important in life than anything else.
B. African children are different in a way.
C. African children should be treated fairly.
D. We should express our love in time.
59. The best title for the passage would be __________
A. Give every child two sweets      B. Tanzile’s love for her sister
C. One for my sister               D. Change your attitude to African children
