   Blind people can read. They do so by running their fingers along a line of raised points or dots on paper. Of course, they first have to learn the code（代码）. Here are some examples of it. One dot stands for the letter “A”. Two dots side by side mean “C”. Four dots arranged to look like a box（：：） stand for the letter “G”. By placing the dots in special patterns, all the letters of the alphabet can be formed.

This code was made up by a Frenchman called Louis Braille. Though he could see at birth, he became sightless when he was only three. Braille was cutting leather in his father’s shop. His knife slipped and cut his eye. Infection（感染）spread to both eyes, and he became blind.

At 10, he was placed in a home for the blind. But young Braille had great talent. He became a skilled musician and soon got a job as a church organist（风琴弹奏者）in Paris.

Because he had talent and was quick, he became a teacher at a school for the blind. While there, he heard that a captain had sent messages to his soldiers that they could read at night without light. His messages were in the simple form of raised dots and dashes. This was the clue Braille needed. At the age of 15, he worked out his own six-dot code. Each group of dots is called a cell. The cells are three dots high and two dots wide. For the rest of his life, Braille taught his young flock to read both written and musical works using his code.

For the last 17 years of his life, Braille was ill with tuberculosis. He died at the age of 43.

   From Japan to Detroit, automobile manufacturers have been busy creating the green car, a vehicle that, in all its forms, promises to be one of the cleanest technologies on earth. To create the green car of the future, say designers, they will replace dangerous substances with safe ones, recycle car parts from antifreeze to old tires and develop alternative fuels.

To meet high environmental standards, automakers began renovating（翻新）their practices at the heart of the matter: the manufacturing process.

At General Motors（GM）a two-seat electric car named the Impact can travel 110 to 160 kilometers on a single charge, depending on driving habits and conditions. GM will begin the consumer test to the Impact in 12 U. S. cities this year. About a thousand people have been selected to drive the vehicle for two-and four-week periods.

Meanwhile, another alternative to standard gasoline-powered cars is Volkswagen’s Golf Ecomatic, recently introduced in Europe and powered by a diesel（柴油）engine that shuts down automatically whenever the car doesn’t require the force of push — while drivers are waiting at traffic lights, slowing to a standstill in heavy traffic or driving downhill. In city traffic alone, Volkswagen engineers expect 60 percent of the trip is spent either moving without its engine turned on or waiting, and overall the carbon dioxide emissions（排放物）produced by the Golf Ecomatic are 22 percent less than those of a standard diesel-powered automobile.

In the end, the green car will be good not only for the environment but also for business. In the long run environmental success is essential to business success, and many companies have recognized this reality, as a growing number of people want to purchase products from environmentally responsible firms.

【小题1】What is the main purpose of automakers worldwide designing the green car?

A．To increase the efficiency of fuels now in use.

B．To solve the problem of the ever-worsening fuel shortage.

C．To meet high environmental standards.

D．To clear the world of waste car parts.

【小题2】Which of the following is the chief advantage of Golf Ecomatic?

A．It shortens waiting time in the street.

B．It reduces carbon dioxide emissions.

C．It cuts down on the consumption of diesel.

D．It ensures the quality of being pollution-free.

【小题3】What can we learn from the last paragraph?

A．Automakers have come to see the advantage of making green cars.

B．Environmental protection should not be achieved at the risk of business failure.

C．Automakers may lose much in the production of green cars.

D．The general public are all eager to use the green car.

【小题4】What is the main purpose of the passage?

A．To educate people on environmental protection.

B．To list the advantages of green cars over traditional ones.

C．To explain the process of developing green cars.

D．To inform people of the development of green cars.

   A new keyboard can tell whether you are its owner. The keyboard records information about the typing pattern（模式）and sends it to a computer program. The program then checks to see if the pattern matches the right user. If not, an alarm sounds, and the computer locks the typist out. It locks out everyone else, even if the person knows the password. What's more, this equipment needs no batteries. It collects all the energy it needs from your actions of typing. Besides, the keyboard is also self-cleaning and the keys are free of damage from water, oil and dirt.

The keys of the new keyboard are made of the same inexpensive plastic that might be found on any other standard keyboard. But instead of being smooth, the keys have millions of tiny plastic nanowires（纳米线）on their surface area, increasing the effective contact areas between the plastics and fingers. This guarantees that there's enough power to run the keyboard as someone types.

Liming Dai, a scientist, did not work on the new keyboard, but he thinks the design could be important in getting better performance from a variety of equipment. "It could also be applied to a touch screen, for example, "Dai says. " Then smart phones and notepads could collect energy from someone's actions of typing or drawing. "

"Future work might make the keyboard even more useful, "Dai adds. " A later design might build tiny capacitors onto the nanowires, "he suggests. Capacitors are little devices that temporarily store electric charge. Those might then be LEDs to light a keyboard in the dark.

Zhonglin Wang is a co-designer of the new keyboard. His team has built a working model of the keyboard. "If a company decides to fund（资助）its production, this keyboard could be in stores in as few as two years, "says Wang.

【小题1】How does the new keyboard tell whether you are its owner？

A．By matching the typing pattern to the right user.

B．By sending alarms to a computer program.

C．By checking the right user's passwords.

D．By just recording information about the typing pattern.

【小题2】Why are there many nanowires on the surfaces of the keys？

A．To keep the keyboard free of damage.

B．To improve the speed of typing.

C．To make the keys smooth.

D．To help produce power.

【小题3】What's Dai's attitude to the new keyboard？

A．Unconcerned.	B．Doubtful.
C．Positive.	D．Critical.

【小题4】What is the best title for the text？

A．A New Keyboard Made of Nanowires

B．A New Keyboard Entirely Owned by You

C．A New Keyboard's Future

D．A New Keyboard Powered by Typing

   Self-driving cars are so popular that the University of Michigan has even established a town called Mcity to allow car manufacturers to safely test their autonomous cars.

While Mcity can be used to simulate（模拟）many real-life road conditions，it can't help test gestures drivers use to communicate their intention（意图）to other drivers，pedestrians or cyclists. To find a solution，US car manufacturer Ford，with researchers from Virginia Tech，at the beginning considered using text as a way to communicate the car's intention，but decided it would probably not work universally. The option of using symbols was also rejected，because research shows that a majority of people do not have a good understanding of what they mean.

Finally, the researchers settled on light signals. A white light warned that there were no humans in the car. A slow blinking one indicated that the car was coming to a stop, while a rapidly flashing light cautioned passersby that the car was about to speed up.

Then came the big challenge—testing the signals on real roads. "We needed to try out this new lighting to communicate the intention of the vehicle, but if you've got a driver behind the seat, you still have natural communication between humans," said Andy Shaudt, who led the research team. "So we needed to make it look like a driverless car."

The team designed a car seat costume（戏装）that the driver would wear to cover his or her face and upper body. Of course，the drivers could see very clearly. The researchers then equipped the car with cameras to capture human reactions to a light bar，which flashed one of the three signals when appropriate. Six drivers，all keeping their hands low on the wheel so as not to be noticed，took turns to test driving the car through the busy streets.

The overall reaction to the flashing lights was very encouraging. Who knew costumes could be useful for more than Halloween？

【小题1】What did the team first consider using as a way to communicate the car's intention?

A．Light.	B．Language.
C．Symbols.	D．Sound.

【小题2】The underlined word "they" in the second paragraph refers to ________.

A．symbols	B．drivers
C．researchers	D．flashes

【小题3】What does a rapidly flashing light mean?

A．The car was coming to a stop.

B．There was no driver in the car.

C．The car was about to speed up.

D．The car was about to slow down.

【小题4】The car seat costume was intended to ________.

A．amuse the driver	B．attract the pedestrians
C．warn the cyclists	D．confuse the people
