The exhibition was held between April 23 and May 2．Although renowned companies showed off their top models，it wasn’t just their expensive sports cars that grabbed people’s attention．
Concept cars are a way for designers to test out their ideas on the public with complete freedom．They can try out cars with special features that could not be massively（批量）produced easily．
Designers don’t have to follow industry rules；they don’t even need to worry about whether their cars would be followed on the roads．
At the Beijing Auto Show，the@Ant by Chery was one concept car to draw a lot of attention．China Daily called it‘‘the very definition of a concept car”．
The vehicle is powered by electricity and is capable of driving itself．But the magic doesn’t end there．
The@Ant was inspired by actual ants．According to Car News China，with the help of automated telemetric systems，@Ants are able to“see” other@Ants and compare destination information. If two are heading the same way for a while, the vehicles connect, with one car’s rear (后面的)wheels matching up with the front wheels of another car．Up to 10@Ants can be put together and will automatically connect to form a“train"．This will help save energy while traveling, as well reducing traffic jams.
The car sounds like a great idea．Further research will be needed to turn this concept car into something for the market，but concepts like Cherry’s show how carmakers are working for cleaner and greener vehicles．It’s like what the@Ant motto says，“Exploring future human beings’lifestyles”．

Zhou Yunyun，22，a senior finance major at Jilin University，has decided that instead of traveling to Hainan province，he will kill the time by playing computer games with his online friends．
“I"m used to chatting and playing with them every day．It’s just fun to make friends this way，”he said．“When I returned home in past years，my relatives always asked me a lot of questions about my plans after graduation．They had high expectations of me，which made me feel stressed，” said Zhou．
The campus，usually lively，will probably turn into a death town，with most restaurants，shops and student centers closed during the break．But there are also a few advantages，according to Jia Debao，2 1，a junior majoring in administration at China Agricultural University．“I might feel a bit lonely，but at least I can stay away from my parents’ complaining and enjoy the peaceful and quiet stay，” he said．“More importantly，I can enjoy the high speed of the Internet，I can always find empty seats in classrooms，and I don’t have to wait to use the bathroorm” But education experts recommend students who stay on campus to come up with more interactive plans．That’s because communication on the Internet can’t replace real life interpersonal relationships．
Society has promoted a kind of“couch potato" or close-in culture among some young people, according to Shi Tongyu, a researcher at the Chinese Academy of Social Sciences. He warned that this kind of lifestyle can damage students’ mental and physical development.
“When you constantly stare at a computer screen and type on your keyboard，you gradually lose the ability to socialize and survive normally，"said Shi．“A human’s most important task is to survive，which cannot be completed by staying at home all the time． Instead，it must be achieved through real life experience and communication．”

| A．he will miss his parents a little bit |
| B．there will be more seats in classrooms |
| C．he will have a quiet and peaceful break |
| D．the speed of the Internet will get faster |
| A．inactive person | B．close friend |
| C．sociable student | D．addicted gamer |
| A．To do some traveling． |
| B．To stay more with families． |

The Gaze Group has been developing eye-controlled computer technology for nearly 20 years．But those devices have been firstly designed to help those with disabilities，and are very expensive．
“After a while，we figured out that probably the best way is to go for a mass-market way，” says Gaze’s Sune Alstrup Johansen．“where everybody would have this available．"
Johansen and some of his colleagues have formed a new company，the Eye Tribe，which is hoping to develop the technology on a mass commercial level．
The technology works with the help of the computing device toward the user’s face． After making sure of the user’s eye movements，the technology is then able to easily find where a person’s eyes are moving，and then allow the eyes to control a cursor（光标）．
“Our software can then determine the location of the eyes and know where you’re looking on the screen to make sure what you’re looking at，“reads an explanation on the Eye Tribe site．
There has been a gradual change toward hands-free technology in recent years， particularly in the gaming world．Recently Xbox released the Kinect device，which lets users control their Xbox and play certain games using only their hands，legs and voices． But still，most of these devices have been more of a gimmick than a practical way to use one’s hands to control a mobile device．Johansen said a replaceable filter（滤光器）would be a cheap，convenient way for most consumers．
And even as companies like The Eye Tribe work to create such a product for the average user, making the eye-controlled technology more accessible and less expensive will have similar benefits for physically disabled users.

Let"s start with a very simple white puffy cloud — a cumulus cloud（积云）. How much does the water in a cumulus cloud weigh? Peggy LeMone, senior scientist at the National Center for Atmospheric Research in Boulder, Colorado, did the numbers. "The water in the little cloud weighs about 550 tons," she calculates. "Or if you want to convert it to something that might be a little more meaningful … think of elephants."
The thought of a hundred elephants-worth of water suspended(悬浮的) in the sky begs another question — what keeps it up there?
"First of all, the water isn"t in elephant-sized particles（微粒）, it"s in tiny tiny tiny particles," explains LeMone. And those particles float on the warmer air that"s rising below. But still, the concept of so much water floating in the sky was surprising even to a meteorologist like LeMone. "I had no idea how much a cloud would weigh, actually, when I started the calculations," she says.
So how many elephant units of water are inside a big storm cloud—10 times bigger all the way around than the "puffy" cumulus cloud? Again, LeMone did the numbers: About 200,000 elephants.
Now, ratchet up(略微调高) the calculations for a hurricane about the size of Missouri and the figures get really massive(巨大的). "What we"re doing is weighing the water in one cubic meter theoretically pulled from a cloud and then multiplying by(乘上) the number of meters in a whole hurricane," she explains.
The result? Forty million elephants. That means the water in one hurricane weighs more than all the elephants on the planet. Perhaps even more than all the elephants that have ever lived on the planet.
小题1:The weight of is NOT mentioned in the passage.
| A．a cumulus cloud | B．a tornado |
| C．a hurricane | D．a storm cloud |
| A．She found it not convincing. |
| B．She thought it needed further calculations. |
| C．She was quite surprised at it. |
| D．She considered the calculations inaccurate. |
| A．A storm cloud weighs about 200,000 elephants. |
| B．The water in a hurricane weighs more than that in any other kind of cloud. |
| C．There are less than forty million elephants living on the earth. |
| D．The water in the cloud is in very tiny partials. |
| A．How Much a Cloud Weighs | B．How Much a Hurricane Weighs |
| C．Surprising Results | D．Elephants in the Sky |
Charles Wiesenthal, who was born in Germany, designed and received a patent on a double-pointed needle that eliminated the need to turn the needle around with each stitch (缝合) in England in 1755. Other inventors of that time tried to develop a functional sewing machine, but each design had at least one serious imperfection.
Frenchman Barthelemy Thimonnier finally engineered a machine that really worked. However, he was nearly killed by a group of angry tailors when they burned down his garment factory. They feared that they would lose their jobs to the machine.
American inventor Elias Howe, born on July 9, 1819, was awarded a patent for a method of sewing that used thread from two different sources. Howe’s machine had a needle with an eye at the point, and it used the two threads to make a special stitch called a lockstitch. However, Howe faced difficulty in finding buyers for his machines in America. In frustration, he traveled to England to try to sell his invention there. When he finally returned home, he found that dozens of manufacturers were adapting his discovery for use in their own sewing machines.
Isaac Singer, another American inventor, was also a manufacturer who made improvements to the design of sewing machines. He invented an up-and-down-motion mechanism that replaced the side-to-side machines. He also developed a foot treadle (脚踏板) to power his machine. This improvement left the sewer’s hands free. Undoubtedly, it was a huge improvement of the hand-cranked machine of the past. Soon the Singer sewing machine achieved more fame than the others for it was more practical. It could be adapted to home use and it could be bought on hire-purchase. The Singer sewing machine became the first home appliance, and the Singer company became one of the first American multinationals.
However, Singer used the same method to create a lockstitch that Howe had already patented. As a result, Howe accused him of patent infringement (侵犯). Of course, Elias Howe won the court case, and Singer was ordered to pay Howe royalties (版税). In the end, Howe became a millionaire, not by manufacturing the sewing machine, but by receiving royalty payments for his invention.
小题1:Barthelemy Thimonnier’s garment factory was burned down because __________.
| A．people did not know how to put out the fire |
| B．Elias Howe thought Thimonnier had stolen his invention |
| C．the sewing machines couldn’t work finally |
| D．workers who feared the loss of their jobs to a machine set fire |
| A．Because the judge was against Singer for his unfriendly attitude. |
| B．Because Howe had already patented the lockstitch used by Singer. |
| C．Because Singer had borrowed money from Howe and never repaid it. |
| D．Because Singer and Howe had both invented the same machine. |
| A．A Stitch in Time Saves Nine |
| B．The Case between Howe and Singer |
| C．Patent Laws on the Sewing Machine |
| D．The Early History of the Sewing Machine |
