When a computer works on a group of programs, it can get very hot. Cooling the computer can cost a lot. So some scientists wonder what would happen if the heat from the computer could be used.
Large Internet companies (公司) such as Google and Microsoft have thousands of computers. As these computers deal with information, they produce lots of heat, so they need huge cooling systems (系统). These systems send the heat into the air.
A company in Holland (荷兰) thinks paying to make the computers work and then paying again to cool them are a waste of energy. So the company developed a special device—the e-Radiator.
Boaz Leupe, head of the company, says that e-Radiator works as a heating system and saves money. He explains that the energy is used twice—once to heat the home and once to cool the computer and that the users don’t have to pay to cool their computers.
Five homeowners in Holland are testing the heating system in their homes.
“We pay for the computer using, so, in that way, homeowners get heating for free,” Boaz says.
Jan Visser is one of the homeowners. “If you use the computer more, the e-Radiator producers more heat, ”he says, “It cannot provide enough heat if you don’t use your computer often.” But he is ready to try it. It’s a great help for his family.
The company says e-Radiators produce heat temperatures of up to 55℃. It says the system could save its users about $440 a year.Before the e-Radiator appears, usually the heat of a computer ______.
| A．is sent into the air | B．helps the five homeowners |
| C．is used twice | D．makes the computer work better |
The e-radiator is mainly used _____.
| A．to drive the computer | B．to help Microsoft |
| C．to heat the computer | D．to provide heat |

What’s the red star in the sky through a telescope(望远镜)? It is Mars. Do you want to know more about it? Take the “Mars Orbit Express”!
“Mars Orbit Express” is a space probe (探测器). It was sent towards Mars by American scientists on August 12th，2005. Its tasks are to study Mars’ atmosphere and return photos to Earth. But before that “Mars Orbit Express” must travel about 100 hundred million kilometers and seven months. It reached Mars’ orbit(轨道)in March，2006.
Mars and Earth have similar weight and size. However，Mars is closer to the sun than Earth. Mars is very cold. The average temperature is below 50℃. The temperature at noon only reaches 20℃ during a Mars day. Its atmosphere is mostly CO2. It has much sand and two moons---Phobos and Deimos.
Scientists think Earth and Mars had similar beginnings 4.6 billion years ago. But while Earth supports millions of lives，Mars becomes bad. “Earth easily could have turned out like that.” said an scientist, “It is important for us to find out why and Mars Orbit Express’ should do that.” “Mars Orbit Express” also would help scientists to learn what might happen to Earth in the future. “Mars Orbit Express” would work for about four years. What can you see through a telescope when watching Mars? ________.
| A．Much sand | B．A red star | C．Its atmosphere | D．Its size |
One of the tasks of Mars Orbit Express is _______.
| A．taking pictures of Mars |
| B．studying the weight of Mars |
| C．finding out distance between Earth and Mars |
| D．telling the time it takes to go from Earth to Mars |
Compared with Earth，_______.
| A．Mars has a long history | B．Mars is big and heavy |
| C．Mars is close to the sun | D．Mars’ atmosphere is mainly O2. |
Which might be the proper title for the passage?
| A．Mars：differences from Earth | B．A probe：to learn more about Mars |
| C．Mars: change of temperature | D．A probe：to tell the future of Earth |
Disasters happen all the time somewhere in the world. Are you ready if one hits your neighborhood next week? Find out what you need to do now before it is too late. Let’s take an earthquake for example.
During an earthquake, get under a strong object like the kitchen table. Don’t leave the building during the shaking, or you might be hurt by falling objects from the outside of the building.
When you are in bed during the night and an earthquake happens，simply roll off the bed. There will be a safe void around the bed.

Try to get into an open area away from trees，buildings，walls，advertisement boards and power lines if you are outdoors.
If you are driving when an earthquake suddenly happens，just stay in your car until the shaking ends. However, if the footbridge falls and breaks your car，get out of it and sit or lie next to it.
