Passage 1
When computer servers operate a complex program, they can get very hot. Cooling the servers can be costly. So researchers asked what would happen if the heat created by the servers could be captured and used?
Data centers of large Internet companies such as Google and Microsoft have thousands of computer servers. As these servers process information, they create large amounts of heat, so they need huge cooling systems. These systems send the heat into the air.
The Dutch company Nerdalize thinks paying for electricity to operate the servers and then paying again to cool them is a waste of energy. So it developed a device called the e-Radiator. It is a computer server that also works as a heating source. Boaz Leupe is the chief executive officer of Nerdalize. He says the e-Radiator saves money because companies don’t have to pay to cool their servers.
“The kilowatt（千瓦）hour you are using is used twice-once to heat the home and once to compute the client’s task without the cooling overhead. ” He says five homeowners in the Netherlands are testing the heating device in their homes. “We reimburse the electricity the server uses, and that we can do because of the computer clients on the other side, and, in that way, homeowners actually get heating for free, and computer users don’t have to pay for the overhead of the data center. ”
Jan Visser is one of the participants in the year-long experiment. He says the amount of heat produced by the e-Radiator depends on the work being done by the computer server. He says it cannot be used as the primary source of heat. But he is ready to try it.
He says if it provides enough warmth, he will be able to use his home’s heating system less, which will save him money. Nerdalize says e-Radiators create heat temperatures of up to 55°C・ It says the devices could save users up to $ 440 in heating costs a year.
21.Why did researchers ask what would happen if the heat created by the servers could be captured and used?
A.Because computers can get very hot.
B.Computer servers is a complex program.
C.Cooling computer servers costs a lot of money.
22.The computer servers in large Internet companies such as Google and Microsoft can .
A. create large amounts of information B. create large quantity of heat
C. manage the huge cooling systems
23.Nerdalize developed the e-Radiator because .
A. e-Radiator cost less energy B. e-Radiator can cool the servers for free
C. e-Radiator can create cold air for free
24.According to Jan Visser, the amount of heat produced by the e-Radiator .
A.depends on the work being processed by PC
B.cannot be used as the home’s heating system
C.cannot be used as the main source of heat
25.The best title for this passage wonld be “
A.The New Way to Heat Homes
B.The New Way to Cool Homes
C.Hot Computers Could Be Used for Free

Passage 2
Engineers who build and program robots have fascinating jobs. These researchers tinker （修*卜）with machines in the lab and write computer software to control these devices. “They’re the best toys out there,” says Howie Choset at Carnegie Mellon University in Pittsburgh. Choset is a roboticist, a person who designs, builds or programs robots.
When Choset was a kid, he was interested in anything that moved-cars, trains, animals. He put motors on Tinkertoy cars to make them move. Later, in high school, he built mobile robots similar to small cars.
Hoping to continue working on robots, he studied computer science in college. But when he got to graduate school at the California Institute of Technology in Pasadena, Choset’s labmates were working on something even cooler than remotely controlled cars： robotic snakes. Some robots can move only forward, backward, left and right. But snakes can twist （扭曲）in many directions and travel over a lot of different types of terrain （地形）. 41 Snakes are far more interesting than the cars, ° Choset concluded.
After he started working at Carnegie Mellon, Choset and his colleagues there bagan developing their own snake robots. Choset’s team programmed robots to perform the same movements as real snakes, such as sliding and inching forward. The robots also moved in ways that snakes usually don’t, such as rolling.
Choset’s snake robots could crawl （爬行）through the grass, swim in a pond and even climb a flagpole.
But Choset wondered if his snakes might be useful for medicine as well. For some heart surgeries, the doctor has to open a patient * s chest, cutting through the breastbone. Recovering from these surgeries can be very painful. What if the doctor could perform the operation by instead making a small hole in the body and sending in a thin robotic snake?
Choset teamed up with Marco Zenati, a heart surgeon now at Harvard Medical School, to investigate the idea. Zenati practiced using the robot on a plastic model of the chest and they tested the robot in pigs.
A company called Medrobotics in Boston is now adapting the technology to surgeries on people.
Even after 15 years of working with his team’s creations, “I still don’t get bored of watching the motion of my robots,M Choset says.
26.Choset began to build robots in high school.
27.Snake robots could move in only four directions.
28.Choset didn, t begin developing his own snake robots until he started working at Carnegie Mellon.
29.Zenati tested the robot on people a任er using it in pigs.
30.The robotic technology for surgeries on people has brought a handsome profit to Medrobotics.

参考范文：
Recently we have conducted a survey among 200 college students to find out their reading preference. As can be seen in the pie chart, 27% of the surveyed said they spent most of their time reading magazines and books for entertainment. What ranks the second are books of literature and applied technology, and they each account for 25%. The percentage decreases to 15% as to students who prefer to read books relevant to their majors, while only 8% tend to read popular science books during their spare time.
It should be noted that books of literature, applied technology, and entertaining books like magazines are main interests of college students. That ‘ s because these kinds of books are fun and easy to read； what ‘ s more, they bring students some cutting-edge information regarding books of applied technology. The percentage of students who like to read professional books is relatively lower may be due to the reason that these books are hard to understand and time-consuming.
To sum up, the data reveals a serious problem that college students ‘ reading preference stays at a relatively shallow level since the percentage of reading magazines exceeds that of literature and professional books. We thus suggest that colorful reading activities like recommending great books be carried out to help students develop capabilities of appreciation and criticism.
