     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.

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

It's official: Text messages mania (狂热) has hit China. Mobile phones are becoming increasingly popular, and so sending text messages is fast becoming the hot new craze among teenagers.

    Twelve Kitties greeted Liu Jiao and wished her a happy new year on the eve of the Chinese lunar calendar's Year of the Horse, making her very excited. According to Xinhua, about 100 million text and picture messages were sent and received by Beijing mobile phone owners during the Spring Festival.

    Liu Jiao is a student at the High School Affiliated to Beijing University of Chemical Technology. A third of the students in her class own mobile phones. She received more than 20 text messages from her friends during the holidays. Most of these messages were general greetings like “Happy New Year”, or humorous sentences, like “Love you as mice love rice”. One of the good wishes she received was made up of the brand names for eight soft drinks, including Coca-Cola and Wahaha. These brand names, when translated into Chinese, are themselves good wishes for happiness or success.

    Besides the convenience of sending text messages, the relatively low cost attracts many teenagers. A common message usually costs only 0.1 to 0. 2 yuan.

    Tan Yingqing, a Senior Two student, said it would have cost her too much to call all of her friends in Beijing because she spent the Spring Festival in her hometown, Shanghai. So she sent mobile phone text messages to them instead.

    According to China Mobile, there has been a lot of promotion (宣传,推广) for messaging through phones since 1997. And the rise in popularity shows that it has worked.

    As the new term starts, Liu turns off her mobile phone. It is not allowed in class because mobile phones could disturb other students. Also, she would rather not be influenced by calls or messages during breaks. However, she often rushes to check her messages as soon as the school day finishes.

1Many teenagers are attracted to send text messages because ________.

    a. it is cool today

    b. mobile phones are popular

    c. it is very convenient

    d. the cost is relatively low

    A. ab

    B. ac

    C. bd

    D. cd

2When Liu Jiao received the text message sent by twelve Kitties on the eve of the Spring Festival, she felt ________.

    A. surprised

    B. bored

    C. excited

    D. unbelievable

3Tan Yingqing sent mobile phone text messages to her friends living in Beijing during the Spring Festival, because ________.

    A. she was staying in Shanghai at that time

    B. she thought it would cost her too much to call them all

    C. she was shy when speaking on the fashion

    D. she wanted to follow the fashion

4The promotion for messages through mobile phones since 1997 in China is ________.

    A. effective

    B. worthless

    C. limited

    D. disappointing

5What is the main idea of the passage?

    A. Text message mania has hit China.

    B. Mobile phone users are fond of developing the function (功能) of mobile phones.

    C. Teenagers like sending text messages in their spare time.

    D. Teenagers at school shouldn't use mobile phones, especially text messages.

四、阅读理解
There’s a box of chocolates in the fridge. It’s been there for more than a week since I was given it as a present. I do love chocolates, but they make me fat if I eat too many! Can I control myself? If I eat one, will I have to eat all of them?
My son Harry is obsessed with playing Wii(/wi:/, 任天堂的一款游戏机) games. Sometimes, it’s difficult to get him to concentrate on his homework because he wants to play some more.
Last week I had to wake up a student in my class. I asked him why he was so tried and he said he had stayed up late to play his favourite Internet game, Farmville. He said he just couldn’t stop playing it! Now his academic work is suffering because he can’t control his urge to play games.
What my son, my student, and I myself need is simply self-control.
In the late 1960’s, American psychologist Walter Mischel launched an experiment about self-control. He left a group of four-year-olds in a room and told them that if they could wait 20 minutes, they could have two marshmallows, a kind of sweet. If they couldn’t wait, he would only give them one.
In videos of the experiment, you can see children squirming, kicking, hiding their eyes—desperately trying to control themselves. Some did wait patiently, while others couldn’t wait a single minute.
Years later, the self-controlled children turned out to get higher SAT scores and got into better colleges. The children who couldn’t wait were more likely to become bullies.
So, the chocolates are still in the fridge. My son Harry is doing his homework with a promise that he can play on the Wii later, and my student says he will try harder to control himself. We all have our own temptations. But if we can control them, we will achieve more.
56. Which of the following is different from the other three?
A. The writer.                                          B. Harry.
C. The writer’s student.                             D. Walter Mischel.
57. We can know from paragraph 5 to paragraph 7 that____________.
A. all the children got two marshmallows
B. all the children waited patiently  
C. self-control can help children succeed later
D. the children who lack self-control get higher SAT scores
58. Which of the following statement is true?
A. The writer is addicted to Wii.
B. The writer’s son is addicted to Farmville.
C. The writer’s student is addicted to chocolates.
D. The writer’s student is addicted to Farmville.
59. What does the underlined word mean in paragraph 5?
A. Something we can eat.                   B. A kind of toy.
C. A kind of mushroom.                     D. A kind of prize.

     It's hard to avoid looking like a fool on April Fool's Day.On April 1 each year, people play tricks on
each other.These tricks are usually silly rather than mean.Classmates sometimes tie each other's shoelaces
to their chairs.Teachers might hand out an impossibly difficult surprise test that scares students before they realize it's only a joke.Newspapers announce fake contests (such as "Win an elephant!") and report on
fake stories (like "UFO" lands in New York City).
