【正文】 wo hours in this house. He decided to get rid of the lump another way. It would mean wasting a good packet of cigarettes，nearly full，but anything was better than taking up the whole carpet and fitting it again. He turned to his toolbox for a large hammer.Eddie didn’t want to damage the carpet itself，so he took a block of wood and placed it on top of the lump Then he began to beat the block of wood as hard as he could. He kept beating，hoping Mrs. Vanbrugh wouldn’t hear the noise and e to see what he was doing. It would be difficult to explain why he was hammering the middle of her beautiful new carpet….The lump was beginning to flatten out.　　After three or four minutes，the job Was finally finished. Eddie picked up his tools，and began to walk out to his car. Mrs. Vanbrugh acpanied him. She seemed a little worried about something.　　“Young man，while you were working today，you didn’t by any chance see any sign of Armand，did you? Armand is my bird. I let him out of his cage，you see，this morning，and he’s disappeared. He likes to walk around the house，and he usually just es back to his cage after an hour or so and gets right in. Only today he didn’t e back. He’s never done such a thing before，it’s most peculiar…”　　“No，madam，I haven’t seen him anywhere，”said Eddie，as he reached to start the Car.　　And he saw his packet of Marlboro cigarettes on the panel，where he had left it at lunchtime……　　And he remembered the lump in the carpet……3What did Eddie Want to do when he had finished fitting the carpet?　　A.

The scientists，F(xiàn) Jeffrey Martin and William Jr.，are proposing a concept，which they have patriotically named Green Freedom, for removing carbon dioxide from the air and turning it back into gasoline.The idea is simple. Air would be blown over a liquid solution which would absorb the carbon dioxide. The carbon dioxide would then be extracted and subjected to chemical reactions that would turn it into fuel. Although they have not yet built a fuel factory，or even a small. prototype，the scientists say it is all based on existing technology. “Everything in the concept has been built，is operating or has a close cousin that is operating.” Dr. Martin said. The proposal does not violate any laws of physics, and other scientists have independently suggested similar ideas.In the efforts to reduce humanity’s emissions of carbon dioxide, three solutions have been offered：hydrogenpowered cars，electric cars and biofuels. Biofuels are gasoline substitutes produced from plants like corn or sugar cane. Plants absorb carbon dioxide as they grow,but growing crops for fuel takes up wide strips of land. Hydrogenpowered Cars emit no carbon dioxide, but producing hydrogen requires energy, and if that energy es from coalfired power plants，then the problem has not been solved. The problem with electric cars is that they have typically been limited to a range of tens of miles as opposed to the hundreds of miles that can be driven on a tank of gas.　　Gasoline，it turns out，is an almost ideal fuel(except that it produces carbon dioxide).If it can be made out of carbon dioxide in the air, the Los Alamos concept may mean there is little reason to switch, after all.　　“It’s definitely worth pursuing，”said Martin I. Hoffert，a professor of physics at New York University. “It has a couple of pieces to it that are interesting. ” Other scientists also said the proposal looked promising but could not evaluate it fully because the details had not been published.3What is most remarkable about the proposal， made by the two scientists？　　A. It is given a patriotic name.　　B. No law of physics is violated.　　C. It is based on existing technology.　　D. Carbon dioxide can be converted into fuel3What is the biggest problem with hydrogenpowered cars？　　A. There is no cheap source of hydrogen.　　B. There might be a safety problem in hydrogen production.　　C. They may still be a cause of global warming. 　　D. They are not suitable for longdistance travel.3If what is proposed by the two scientists bees true，___________　　A. air pollution will，bee a thing of the past　　B. there will be no need for gasoline substitutes　　C. people will be able to use much cheaper engergy　　D. there will be no more biofuelpowered vehicles3Which of the following Call best describe the attitude of Martin I Hoffert to the proposal？A. Indifferent. B. PositiveC. Suspicious. D. CriticalThe passage is mainly written to __________。ll be glad to drop you off on my way to work. A：I’m sorry. He’s not in his office.　　 B：______________　　 A. Are you Sure he will be back soon?　　 B. Would you like to leave a message?　　 C. C
