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 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． |
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?

Mr. Eckerd at the end of the street was a different fellow with a different kind of house. He let kids from the neighborhood come to see his house, but only if they had written permission from their parents, and if he’d already spoken to the parents before.
What made it so different? He shared his home with rescued animals that the county couldn’t keep. He had the permission to have things like monkeys, large cats, and other strange creatures. His house had the ivy(常春藤)-covered brick wall and the iron gate across the driveway. Once you went inside, the hedges(树藤)lining the driveway were carved into the shapes of animals. There were other pretty plants on the grounds, too.
The old brick house held a lot of surprises. The double doors with the lion’s head door knockers opened into a large flat entryway. In the wooden board walls all around, there were fish tanks with colorful fishes. The ceilings were painted with scenes of plants and rare animals. Room opened off from there. Continuing down the hall, you came to a large courtyard, which had been caged in, partly open to the sky .A large group of tiny monkeys shook up and down trees. You had to walk through a caged tunnel into other parts of the house. They called out to whoever walked in, hoping for treats of fruits, nuts, and seeds. Behind that, the hall continued to a room full of snakes and lizards. It felt like a desert in that room, so dry and hot. It was not everyone’s favorite room, but it certainly was interesting. The final room was actually out back, and definitely not something to miss. It was much like a large glass bird cage or a greenhouse. It was there that you would usually find Mr Eckerd on a bench next to some carvings of jungle animals. He was watching the Bengal tiger that wandered back and forth inside the cage.
Mr. Eckerd’s house was the strangest and most unique place in town, a place very well worth seeing.What was different about Mr. Eckerd’s house?
| A．It was big and frightening. |
| B．It was full of flowers and gardens. |
| C．It had wild animals inside and outside. |
| D．It was an amusement park. |
What kind of live animals was NOT at Mr. Eckerd’s house?
| A．Fish | B．Snakes and lizards. |
| C．Monkeys. | D．Elephants. |
What exhibit or animal room seemed to be the least popular for most people?
| A．The tiger. | B．The monkeys. |
| C．The birds. | D．The snakes and lizards. |
According to the story, ______seemed to be Mr. Eckerd’s favorite animal at his house.

The famous director of a big and expensive movie planned to film a beautiful sunset over the ocean, so that the audiences could see his hero and heroine in front of it at the end of the film as they said goodbye to each other for ever. He sent his camera crew (摄影组) out one evening to film the sunset for him.
The next morning he said to the men, “Have you provided me with that sunset?”
“No, sir,” the men answered.
The director was angry, “Why not?” he asked.
“Well, sir,” one of the men answered, “we are on the east coast here, and the sun sets in the west. We can get you a sunrise over the sea, if necessary, but not a sunset.”
“But I want a sunset!” the director shouted. “Go to the airport, take the next flight to the west coast, and get one”
But then a young secretary had an idea. “Why don’t you photograph a sunrise?” she suggested, “and then play it backwards? Then it’ll look like a sunset.”
“That’s a good idea!” the director said. Then he turned to the camera crew and said, “Tomorrow morning I want you to get me a beautiful sunrise over the sea.”
The camera crew were out early the next morning and filmed a bright sunrise over the beach in the middle of a beautiful bay(海湾)。 Then at nine o’clock they took it to the director. “Here it is, sir.” They said, and gave it to him. He was very pleased.
They all went into the studio(摄影棚)。 “ All right,” the director explained, “ now our hero and heroine are going to say goodbye. Run the film backwards so that we can see the ‘sunset’ behind them.”
The “sunset” began, but after a quarter of minute, the director suddenly put his face in the hands and shouted to the camera crew to stop.

When I was 12, all I wanted was a signet (图章) ring. They were the "in" thing and it seemed every girl except me had one. On my 13th birthday, my Mum gave me a signet ring with my initials(姓名首字母) carved into it. I was in heaven.
What made it even more special was that it was about the only thing that wasn't being "replaced". We'd been burnt out in fires that swept through our area earlier that year and had lost everything—so most of the " new" stuff (东西) we got was really just to replace what we'd lost. But not my ring. My ring was new.
Then, only one month later, I lost it. I took it off before bed and it was missing in the morning. I was sad and searched everywhere for it. But it seemed to have disappeared. Eventually, I gave up and stopped looking for it. And two years later, we sold the house and moved away.
Years passed, and a couple of moves later, I was visiting my parents' when Mum told me that she had something for me. It wasn't my birthday, nor was it Easter or Christmas or any other gift-giving occasion. Mum noticed my questioning look. " You'll recognize this one," she said, smiling.
Then she handed me a small ring box. I took it from her and opened it to find my beautiful signet ring inside. The family who had bought our house 13 years earlier had recently decided to do some redecorations, which included replacing the carpets. When they pulled the carpet up in my old bedroom, they found the ring. As it had my initials carved into it, they realized who owned the ring. They'd had it professionally cleaned up by a jeweler before sending it to my mother. And it still fits me.The underlined word "in" in the first paragraph probably means "_____".
| A．fashionable | B．available |

| B．The writer never stopped looking for her ring. |
| C．The writer's ring was cleaned up by the new house owner. |
| D．The writer lost her ring in the morning when she took it off. |
What would be the best title for the passage?
| A．My New Ring | B．Lost and Found |

Rent（出租）a room
Spare room? Not only will a lodger（房客）earn you an income, but also, thanks to the government-backed “rent a room” program, you won’t have to pay any tax on the first ￡4500 you make per year. Try advertising your room on Roomspare or Roommateeasy.
Make money during special events
Don’t want a full-time lodger ? Then rent on a short-term basis. If you live in the capital, renting a room out during the Olympics or other big events could bring in money. Grashpadder can advertise your space.
Live on set
Renting your home out as a “film set” could earn you hundreds of pounds a day, depending on the film production company and how long your home is needed. A quick search on the Internet will bring up dozens of online companies that allow you to register your home for free—but you will be charged if your home gets picked.
Use your roof
You need the right kind of roof, but some energy companies pay the cost of fixing solar equipment (around ￡14,000), and let you use the energy produced for nothing. In return, they get paid for unused energy fed back into the National Grid. However, you have to sign a 25-year agreement with the supplier, which could prevent you from changing the roof. Where can you put an advertisement to rent out a room during a big event?
| A．On Letpark. | B．On Roomspare. |
| C．On Grashpadder. | D．On Roommateeasy. |
If you want to use energy for free, you have to_____.
