    If cars had wings, they could fly and that just might happen, beginning in 2011.The company Terrafugia, based in Woburn, Massachusetts, says it plans to make such a car-plane called “Transition”, to customers(顾客) by the end of 2012. “It’s the next ‘wow’ vehicle,”said Terrafugia vice president Richard Gersh. “Anybody can buy a Ferrari, but as we say, Ferraris don’t fly.”

    The car-plane has wings that unfold for flying—a process the company says takes one minute-and fold back up for driving. A runway is still needed to take off and land.

    The Transition is being marketed more as a plane that drives than a car that flies, although it is both. The company has been working with FAA to meet aircraft regulations, and with the National Highway Traffic Safety Administration to meet vehicle safety regulations.

    The company is aiming to sell the Transition to private pilots as an easier and cheaper way to fly.They say it saves you the trouble from trying to find another mode of transportation to get to and from airports: You drive the car to the airport and then you’re good to go.When you land, you fold up the wings and hit the road. There are no expensive parking fees because you don’t have to store it at an airport—you leave it in the car park at home.

    The car-plane is designed to fly under 10,000 feet. It has a maximum take-off weight of 1,430 pounds, including fuel and passengers.

    The Transition’s price tag: $194,000, But there may be something else you need to pay, like a radio, transponder or GPS and so on.

    So far, the company has more than 70 orders. “We’re working very closely with them, but there are still some remaining steps,” Brown said.

    1.We can learn from the first paragraph that _________.

    A.car-planes will be popular in 2012

    B.people might drive a car-plane in 2012

    C.both Transition and Ferrari can take off and land

    D.Richard Gersh is the vice president of Massachusetts

    2.According to the passage, which of the following is NOT true?

    A.The car-plane needs a runway to take off and land.

    B.A car-plane with radio and GPS will cost $194,000

    C.The car-plane may fly at 8,000 feet

    D.People can park the car-plane in the car park at their home.

    3. Which of the following has the closest meaning to the underlined word “unfold” on this passage?

    A. start B. spread

    C. cover D. travel

    4.What’s the best title for the passage?

    A. Cars With Wings May come true soon

    B. A Ferrari or a Car Plane

    C. A Easier and Cheaper Way to Fly

    D. Cars With Wings Can Fly as Fast as Planes

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

    Recently, two scientists, Jose Millan and Michele Tavella from the Federal Polytehnic School in Lausanne, Switzerland, show 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 body cells(细胞). These send signals through the spinal cord(脊髓) to the body part to give us the ability to move. But spinal cord injuries(脊柱受伤) or other conditions can prevent these weak electrical signals from reaching the body part.” Tavella says. “Our system allows disabled people to communicate with outer world and also to control machines.”

    The scientists 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 finds meanings of the signals and commands the wheelchair with an engine. The wheelchair also has two cameras that tell 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 finds meanings of brain signals and turns them into simple commands.” The practical possibilities that BCI technology offers to disabled people can be grouped in two kinds: communication, and controlling objects. 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 get advantages from. And the other is sure that they can use the technology for long.

    1. BCI is a technology that can________.

    A.help to make computer systems more modern

    B.connect the human brain with computers

    C.help the disabled to be healthier

    D.control a person’s thoughts

    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 money 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 Sickness
