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 |

Since last year I've given up driving and taken the bus to work every day, which has aroused quite a bit of curiosity among colleagues because few people take a bus to work in my office.
My easy explanation is that I'm tired of driving, and taking the bus allows me to think before my work starts. a day’s , hard, work I ,also, a ride, like,to ,be given , home, after, .
Perhaps everybody would be more convinced(使信服） if I told them that I take the bus because it's quite cheap, while driving a car is expensive and inconvenient.A bus trip costs 0.4 yuan or 6-7 cents with the use of a stored value card（储值卡）, which is almost free if you consider a Coke costs five times that or more. Beijing has a flat-rate subway fare with unlimited transfers of 2 yuan per single-trip ticket. I would take the more comfortable subway, if it was closer to my home and workplace.
But most of my colleagues, especially the younger ones who want to own a car, have responded with disbelief, as they picture me walking to the bus stop under smoggy skies. I believe they would be amused(被逗乐的）if they read the findings of a study of British workers, which found that going to work by bus or train has become very popular. Because most journeys will not only include walking to the bus station or stop, but also include time to read or talk to friends while traveling according to recent British media reports.文中划线的单词的汉语意思是__________________

The English language is different from any other language. Yet English words do not stay the same. The language is always changing. We need new words for new inventions and new ideas. Different words come into use, or older words are used in a new way.
English can change by borrowing words from other languages. Tomato was borrowed from Mexico and pajamas from Indian. The word coffee came from Turkey, and tea came from China. Now new space and science words are being borrowed from other countries, too.
New words are also made by adding two words together. Strawberry, popcorn, and grandfather are words made up of two parts.
Sometimes new words are shorter forms of older words. The word photo was made from photograph by cutting off the end of the longer word. Plane was made by cutting off the front part of airplane. Smog was made by using only the first two and last two letters from the words smoke and fog.
The names of people and products can become new words. Our sandwich was named after a man named Sandwich. Scotch Tape, Band-aid and Jello were names made up by the companies that first made the products.
