【正文】 s called Freon, which is far more damaging than carbon dioxide.Now Malcolm McCulloch, an electrical engineer at Oxford, is leading a threeyear project to develop appliances that can be used in places without electricity.His team has pleted a model machine of a fridge patented in 1930 by Einstein. It used only pressurized gases to keep things cold. The design was partly used in the first refrigerators, but the technology was dropped when more efficient pressors (壓縮機(jī)) became popular in the 1950s. That meant a switch to using Freon.Einstein’s idea uses butane (a gas) and water and takes advantage of the fact that liquids boil at lower temperatures, when the air pressure around them is lower.“If you go to the top of Mount Qomolangma, water boils at a much lower temperature than it does when you’re at sea level and that’s because the pressure is much lower up there,” said McCulloch.At one side is the evaporator (蒸發(fā)器), a bottle that contains liquid butane. “If you introduce a new vapor above the butane, the liquid boiling temperature decreases and, as it boils off, it takes energy from the surroundings to do so,” says McCulloch. “That’s what makes it cold.”The gas fridges based on Einstein’s design were replaced by Freonpressor fridges partly because Einstein’s design was not very efficient. But McCulloch thinks that by changing the design and replacing the types of gases used it will be possible to greatly increase the efficiency.However, McCulloch’s fridge is still in its early stages. “It’s very much a model machine,” he said. “Give us another month and we’ll have it working.”57. According to the passage, an early invention by Albert Einstein _______.A. has been rediscovered because it costs much less and works more efficiently B. is being redesigned because it could be used in places without electricityC. has just been found to be energysaving and environmentally friendly D. will be fully made use of and bee the fridge of the future58. Which of the following is TRUE according to the text?A. Freon was used in fridges long before the 1950s.B. Freon is what makes current fridges big polluters.C. McCulloch thinks he could improve Einstein’s design by using other types of vapors.D. The fridge that Malcolm McCulloch and his team designed will be put into production soon.59. We can learn from the text that the model machine pleted _______.A. changed the air pressure around itB. was tested on the top of Mount Everest C. increased the liquid boiling temperatureD. used only pressurized gases to keep things cold60. McCulloch’s words in Paragraph 6 _____.A. serve as an explanation for the principle behind Einstein’s fridgeB. give you the reason why Einstein39。s health budget be used for health education and disease prevention instead of treatment. Actually, many kinds of diseases are preventable in many ways and preventing a disease is usually much cheaper than treating it. For example, people could avoid catching a cold if they dressed warmly when the weather starts getting cold. But many people get sick because they fail to do so, and have to spend money seeing a doctor.Daily habits like eating more healthy food would have kept millions of families from being bankrupt if the patients had taken measures for early prevention. For instance, keeping a balanced diet, such as not consuming too much animal fat and insuring a steady intake of vegetables and fruits, seems to be quite important.One very effective and costless way of prevention is regular exercise, which is necessary for a healthy mind and body. Regular exercise, such as running, walking, and playing sports is a good way to make people feel better or reduce stress.In addition, health education plays a key role in improving people39。高考資源網(wǎng)About a month ago while in the drive through(免下車(chē)餐館) at Starbucks I noticed a woman in a car behind me who appeared to be having a bad day. The 21 moved slowly and at one point while 22 forward the woman behind me bumped my car. I could tell this worried and 23 her. She was looking at the side view mirror 24 Why me? Why today?When I pulled up and paid for my coffee I gave the woman a 25 and paid for her muffin.Just 30 minutes 26 I was again waiting in line at the Starbucks. I heard a car door slam but thought 27 of it. I was startled when this same woman 28 to my driver side window. She handed me a twenty dollar bill and 29 a smile, saying, This is for you. You were the one who gave me the hope of life originally 30 .” Ks5uIt was amazing! It was as if this woman had been waiting to show her 31 for what I had done! I know in most 32 it’s best to have this 33_. That means perhaps she understands the 34 of giving a smile. The most amazing thing? The day I bought her coffee and muffin for her, the entire day after, I was filled with this sense of hope. Wondering if what I had done had made a 35 and hoping that what I had done had made her feel 36_.When she got back into her car today she was all Smiles. I could tell she felt the 37 way I had that one early Sunday morning. It was nice to have my drink 38_, but what made me feel even better was seeing the happiness and smiles on her face.As I pulled out of the drivethrough she 39 and yelled out, Have a good day! I yelled back, You too! The smile has 40 my day from a Why Me Day into a day of happiness.21．A．line B．bus C．cloud D．river22．A．looking B．walking C．pulling D．turning23．A．concerned B．frightened C．injured D．discovered24．A．reading B．laughing C．reminding D．wondering25．A．hand B．gift C．smile D．confidence26．A．a(chǎn)fter B．a(chǎn)go C．later D．long27．A．something B．a(chǎn)nything C．nothing D．everything28．A．shouted out B．looked over C．gave in D．came up29．A．a(chǎn)lso B．still C．yet D．therefore30．A．well B．right C．too D．much31．A．generosity B．idea C．regret D．a(chǎn)ppreciation32．A．places B
