Questions 166-168 refer to the following article. Kaiser Chemical Co. is proud to submit its entry to the 7th annual Innovation Contest to be held in the San Diego Convention Center, November 24-26, 2007. The product is a new type of insulation material. Thanks to its unique microstructure, it can keep the houses warmer in the colder winter months and cooler in the summer. This means that using our new insulation will result in a substantial reduction in the consumer heating and cooling bills. In addition, our new insulation is made without any harmful chemicals. Moreover, our new insulation functions equally well in humid and dry climates. We invite interested scientists and observers to visit our information booth in the annual Innovation Contest and to meet our company CEO, Mr. Howard Peterson, who is giving a presentation on the product at 10 a.m. on November 25.
单选题
What can be inferred about the new insulation? A. It is most useful in small houses. B. It represents innovation in chemistry. C. It is currently being used in the San Diego Convention Center. D. It needs to be tested in dry climates.
【正确答案】
B
【答案解析】高级问题 文中明确提到，新绝缘材料的特点是“没使用任何化学产品(Without any harmful chemicals)”，由此可推知，这种绝缘材料是“化学领域的创新产品(innovation in chemistry)”。原文中有这句话: Our new insulation functions equally well in humid and dry climates. (无论在潮湿还是干燥的气候下，新绝缘材料都将发挥相同的功效。)故(D) It needs to be tested in dry climates. (此种绝缘材料需在干燥气候下进行测试。)与原文内容不符。
单选题
What is NOT mentioned as an advantage of the new insulation? A. It reduces heating bills. B. It is made of safe chemicals. C. Internal insulation costs less than external insulation. D. It functions well in dry climates.
【正确答案】
C
【答案解析】中级问题 通过166题的分析可知(B)、(D)两项在文中提到过，故可排除。另外新绝缘材料的优点在于“可大量节省冷暖气费用(a substantial reduction in the consumer heating and cooling bills)”，因此(A)项也和原文相符。而(C)项，文中没有提到内部绝缘材料和外部绝缘材料比较的细节，故应选此项。
