The tapeworm was dead when taken out. does the underlined word mean? A. Feeling sick. B. Feeling weak. C. Feeling sleepy. D. Having a fever. D Researchers at Stanford University have developed a new material that can move heat out of buildings and into space. The researchers say the material can cool buildings even on hot days. The cooling material is a very thin sheet with many layers that could be placed on a roof like solar panels（电池板） . However, instead of turning sunlight into energy as solar panels do, the material turns heat into infrared radiation(红外辐射 ). Shanhui Fan, an electrical engineering professor at Stanford University, says that the panels have a layer of material that is like sand. He says that the panels act like a mirror. They take heat out of buildings and reflect the light from the sun. He says both the heat and sunlight are sent 100 kilometers into outer space. It39。 s a structure that cools itself without using electricity, even under the sun. So, what it does is basically radiate heat to outer space and also reflect the sunlight, so it doesn39。 t get heated up by the sun. The panels are cool to the touch, even in the sun. Researchers say they can reduce the indoor temperature to nearly 5 degrees Celsius below the temperature outside. Mr Fan says it is like having a window into space. He says the heat is sent directly into space without warming the air. “In areas where there is no electricity, there is a significant potential benefit for storing medicine or even food. In many of these situations, being able to reduce the temperature is important. And this would provide a way to do it. They say the main problem is creating actual cooling systems using the hightech panels. They say it may be possible to develop a cooling spray that could be used on existing solid structures. The researchers believe the cooling spray technology could be developed in the next three to five years. They say as much as 15 percent of the energy used in the United States is spent providing power to air conditioning systems. 32. What is mainly talked about in the passage? A. A new material that cools buildings. B. New energysaving buildings. C. A new technology to store medicine and food.. D. A cooling system to replace air conditioners. 33. How does the material work to cool buildings? A. By making panels into mirrors with the material. . B. By absorbing sunlight and turning it into energy. C. By spraying water on the building structures. D. By radiating and reflecting heat. 34. What will the researchers do in the next years? A. Do more experiments to test the material. B. Develop a cooling spray for existing structures. C. Cut the cost of the cooling system. D. Promote the use of the cooling system. 35. What can we infer from the passage? A. The cooling system could save more energy for electricityshort area. B. The cooling system will surely be available in three or five years. C. The cooling system could have possible use in the US. D. The cooling system will take the place of air condition system. 第二节（共 5小题；每小题 2分，满分 10分） 根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。 选项中有两项为多余选 Homesickness is a very mon experience, no matter what your age or background is. 36 It can bring about feelings of loss, sadness for the place and people you39。 ve left behind. Here are some tips to help you overe the feelings of homesickness. Get your mind off home by distracting yourself. 37 For example, you might think about the times you and your family don39。 t get along, make life hard for one another and even argue! Of course, there39。 s no need to overdo this but it does serve you well to remember that life is full of。
