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.
1.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.
2.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
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

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。
Every Wednesday, I go to Cantata Adult Life Services,a local retirement community in Brookfield, Illinois, US, with my classmates to do community service.
After my very first visit to Cantata,my life changed forever.That may sound a bit dramatic, but volunteering with the elderly has changed my views on life.
Our visits last about an hour, and we bring 25?30 students every time. We play board games and cards with the residents while we're there.
You can watch all the movies and TV shows you want about “life back then”, but nothing compares to talking to the people who were actually there. Just hearing their stories has touched me in a way I never thought possible.
Whether it was talking to 98?year?old “Hurricane Hilda” about her glory days as a roller skater or chatting with Lou about the times she danced with a famous actor, I was completely attracted by every single memory the residents wanted to share with me.
Even the residents who don't have amazing memories make the experience satisfying.I remember visiting Mrs. Robinson. She couldn't recall much about her past, but she told me she'd never forget how kind I was just to listen to her “rambling(漫谈)”. It made me realize that it's the little things that make life worth living. That's something I won't forget anytime soon.
If there's one thing I've realized in my three years of visiting Cantata, it's that presence—just being there—means more than anything to many of the residents. And despite how busy our lives are, there's always time to make someone's day.
For me, it feels great to be a source of happiness, a smile on a bad day or a listening ear for old memories. And at the end of the day, that's all that matters.
It's easy to feel like you don't have anything in common with the elderly—especially when you're a teenager. But that's not true at all.
I hate to be overly clichéd(陈词滥调的) here, but age really is just a number. As young adults, it's important for us to realize this sooner rather than later.We can learn a lot from the elderly, and they can often benefit from teenagers too.
1.What do the volunteers do according to the passage?
A.They share everything with the residents.
B.They play board games and cards with the residents.
C.They watch the residents play games.
D.They buy gifts for the residents.
2.According to the writer, what is the most important thing that volunteers can do for the elderly?
A.Playing with them.
B.Benefiting from them.
C.Helping them.
D.Being there with them.
3.What does the writer want to tell us by writing this passage?
A.We don't have anything in common with the elderly.
B.Age is just a number.
C.It is important to help the elderly.
D.Young adults and the elderly can benefit from each other.

The freezing Northeast hasn’t been a terribly fun place to spend time this winter, so when the chance came for a weekend to Sarasota, Florida, my bags were packed before you could say “sunshine”. I left for the land of warmth and vitamin C(维生素C), thinking of beaches and orange trees. When we touched down to blue skies and warm air, I sent up a small prayer of gratefulness. Swimming pools, wine tasting, and pink sunsets(at normal evening hours, not 4 in the afternoon) filled the weekend, but the best part - particularly to my taste, dulled by months of cold- weather root vegetables- was a 7 a.m. adventure to the Sarasota farmers’ market that proved to be more than worth the early wake-up call.
The market, which was founded in 1979, sets up its tents every Saturday from 7:00 am to 1 p.m., rain or shine, along North Lemon and State streets. Baskets of perfect red strawberries; the red-painted sides of the Java Dawg coffee truck; and most of all, the tomatoes: amazing, large, soft and round red tomatoes.
Disappointed by many a broken, vine-ripened(蔓上成熟的) promise, I’ve refused to buy winter tomatoes for years. No matter how attractive they look in the store, once I get them home they’re unfailingly dry, hard, and tasteless. But I homed in, with uncertainty, on one particular table at the Brown’s Grove Farm’s stand, full of fresh and soft tomatoes the size of my fist. These were the real deal- and at that moment, I realized that the best part of Sarasota in winter was going to be eating things that back home in New York I wouldn’t be experiencing again for months.
Delighted as I was by the tomatoes in sight, my happiness deepened when I learned that Brown’s Grove Farm is one of the suppliers for Jack Dusty, a newly opened restaurant at the Sarasota Ritz Carlton, where - luckily for me - I was planning to have dinner that very night. Without even seeing the menu, I knew I’d be ordering every tomato on it.
1. What did the author think of her winter life in New York?
A. Exciting. B. Boring.
C. Relaxing. D. Annoying.
2. What made the author’s getting up late early worthwhile?
A. Having a swim. B. Breathing in fresh air.
C. Walking in the morning sun. D. Visiting a local farmer’s market.
3. What can we learn about tomatoes sold in New York in winter?
A. They are soft. B. They look nice.
C. They taste great. D. They are juicy.
4. What was the author going to that evening?
A. Go to a farm. B. Check into a hotel.
C. Eat in a restaurant. D. Buy fresh vegetables.
