Since the 1970s, scientists have been searching for ways to link the brain with computers. Brain-computer interface (界面) (BCI) technology could help people with disabilities send commands to machines.

Recently, two researchers, Jose Milan and Michele Tavella from the Federal Polytechnic schooling 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(頭皮) 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.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

4.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

6.Charles Chaplin,who died in 1977,is considered one of the greatest and funniest actors in the history of the cinema.During his lifetime,he acted in 13films,and he wrote,directed and acted in 69other films.
Chaplin was born in London in 1889.When a poor boy,he was often seen waiting outside the London theaters,hoping to get work in show business.He could sing and dance,and above all,he knew how to make people laugh.But he couldn't get work and therefore wandered about the city streets.Sometimes he was sent away to a home for children who had no parents.
Charlie Chaplin first acted when he was five.He broke into show business because his mother,a music-hall performer,lost her voice during the performance and had to leave the stage,and Charlie went on and sang a well-known song.Halfway through the song a shower of money poured onto the stage.Charlie stopped singing and told the audiences he would pick the money first and then finish the song.The audiences laughed.This was the first of millions of laughs in Charlie Chaplin's fabulous career(神話般的生涯).
Twenty years later the same Chaplin became the greatest and best loved comedian in the world.His dream came true in the end.Chaplin became world-famous and almost a king in the world of the film.
Even people who don't understand English can enjoy Chaplin's films because they are mostly silent.The equipment for adding sound to films had not yet been developed.The development of films with sound became a problem for Chaplin,as he was uncertain about making films with dialogues.Instead,he continued to make films without dialogue,but he added music,which he wrote himself.It isn't what he says that makes us laugh.His comedy doesn't depend on words.It depends on little actions which mean the same thing to people the world over.
Chaplin's later films,however,were not well received.Chaplin lived most of his life in America and the last years in Switzerland,where he was buried at Christmas 1977,at the age of eighty-eight.There was sadness all over the world at the news of his death.
In his book,Chaplin tells us how to succeed in life.He says,"You have to believe in yourself.That's the secret."

25.Chaplin is regarded as king of comedy mainly becauseC.
A.he acted out the common human situations best in his comedy
B.he could sing and dance well
C.he knew how to make people laugh
D.lots of people have seen his films
26.What makes people laugh in Chaplin's films?A
A.It isn't his words but his actions
B.Neither his words nor actions
C.Either his words or his actions
D.Not only his words but also his actions
27.The only secret of Charles Chaplin's huge success is thatB.
A.he can make all people,men and women,old and young laugh
B.he has full trust in himself
C.he is always active and hard-working all his life
D.though he is always in trouble,he never loses heart
28.Which of the following statements is true according to the passage?C
A.He was too shy to meet the managers of the theaters.
B.People won't stop laughing until tears run down Chaplin's face.
C.People all over the world can enjoy Chaplin's films without translation because most of them are silent.
D.He wouldn't like to work at the theater.

12.I believe that my country,Poland,is a perfect example for a place where food is particularly important.When we were little children,we began to understand how much a loaf of bread meant to our parents-to some it might sound silly but for me the custom of kissing bread before you started cutting it was simply amazing.It's not so common nowadays to treat food that way,since you hardly ever bake your own bread.Besides,everyone would call you crazy if you tried to kiss every bread roll before you ate them!But though we no longer make our food from scratch (起點(diǎn)),some customs have been kept-that's why I feel so sorry every time I have to throw any food away-even though I no longer live with my parents and nobody would blame me for this anymore!
Many people of our nation are still working as farmers,eating what they grow and harvest and therefore enjoying everything more.It's widely known that you value more anything that needs your effort in the first place.In most homes in Poland,especially those of farmers,the whole family would try and have their meals together-extremely difficult now,but so rewarding!You can share other members'troubles and successes,give your children some attention,or just sit down for a moment,instead of rushing through life aimlessly.Furthermore,your body,and stomach in particular will be very grateful for such a time!
In Poland,a wedding,Christmas or even a birthday is celebrated with a great meal.Women in the house get together and cook,sometimes for a few days before the event,and the extremely good or unusual food will be remembered and widely talked about.
You cannot over-value the importance of food in the country.What's more,almost everyone in Poland will be as interested in the topic as I am.
13.When the writer was a child,he/sheB.
A.found people were crazy about bread
B.began to realize the importance of food
C.thought that cutting bread was amazing
D.learned people hardly baked their own bread
14.The writer feels very sorry when he/she has to throw away any food becauseC.
A.he/she makes food from scratch
B.his/her parents would blame him/her
C.some customs still have effect on him/her
D.many people are still working hard as farmers
15.From the text,we can learn that,in Poland,D.
A.most meals can be interesting topics for a long time
B.the whole family often have meals together nowadays
C.it's common for women to get together to cook for a few days
D.family members can know more about each other by having meals together.

9.Music is magic!Music speaks louder than words and it is a"language"that the whole world can understand.A piece of music can produce a response in the heart and mind.Like feeling an electrical current or receiving a personal radio signal,music has a spiritual effect on a person.Different kinds of music influence people in different ways.
I have listened to music all my life.When I was twelve years old,the Beatles came to America and my whole world opened up.Maybe young people today cannot understand the influence of the Beatles when they exploded across America.Their influence changed the way we dressed,looked,acted and spoke even our culture.The Beatles arrived in America from the UK just under three months after the assassination(暗殺)of President John Kennedy,which had put America into a great depression.And the freshness and lively sprit of the Beatles was exactly what the country needed to refresh itself.
Music links the heart of the hearer with that of the composer.This means that it mixes the spirit of the composer with your spirit when you listen to it.And the music can take your spirit out of your body and transport you into another world.Music has a great way of touching people.Music can make you laugh,cry or shout.It's also a great source of inspiration.
Try this one day and notice what happens:make yourself a cup of tea,sit on your sofa and play one of your favorite songs.Close your eyes,and soon you'll find yourself creating vivid mental images---matching the music that you are listening to.

28.Music has magical power because itD.
A.is a kind of language
B.can be played much louder than words
C.receives a personal radio signal
D.can influence a person's spirit
29.One can learn from the second paragraph that the BeatlesC.
A.were the biggest band in American history
B.a(chǎn)re not accepted by modern American people
C.a(chǎn)ppeared at a special time in American politics
D.represented the roots of American culture
30.One will do all of the following while listening to music EXCEPTC.
A.feeling very refreshed
B.having emotional changes
C.painting some vivid pictures
D.feeling inspired by the composer
31.It can be inferred from the passage that the authorA.
A.has been influenced by the Beatles
B.enjoys drinking tea in his spare time
C.a(chǎn)dmires President John Kennedy very much

I was never very neat, while my roommate Kate was extremely organized. Each of her objects had its place, but mine always hid somewhere. She even labeled(貼標(biāo)簽) everything. I always looked for everything. Over time, Kate got neater and I got messier. She would push my dirty clothing over, and I would lay my books on her tidy desk. We both got tired of each other.

War broke out one evening. Kate came into the room. Soon, I heard her screaming, ‘Take your shoes away! Why under my bed!’ Deafened, I saw my shoes flying at me. I jumped to my feet and started yelling. She yelled back louder.

The room was filled with anger. We could not have stayed together for a single minute but for a phone call. Kate answered it. From her end of the conversation, I could tell right away her grandma was seriously ill. When she hung up, she quickly crawled(爬) under her covers, sobbing. Obviously, that was something she should not go through alone. All of a sudden, a warm feeling of sympathy rose up in my heart.

Slowly, I collected the pencils, took back the books, made my bed, cleaned the socks and swept the floor, even on her side. I got so into my work that I even didn’t notice Kate had sat up. She was watching, her tears dried and her expression one of disbelief. Then, she reached out her hands to grasp mine. I looked up into her eyes. She smiled at me, ‘Thanks.’

Kate and I stayed roommates for the rest of the year. We didn’t always agree, but we learned the key to living together: giving in, cleaning up and holding on.

1.What made Kate angry one evening?

A. She couldn’t find her books

B. She got the news that her grandma was ill

C. She heard the author shouting loud

D. She saw the author’s shoes beneath her bed

2.The author tidied up the room most probably because .

A. she was scared by Kate’s anger

B. she wanted to show her care

C. she hated herself for being so messy

D. she was asked by Kate to do so

3.How is Paragraph 1 mainly developed?

A. By analyzing causes B. By describing a process
