阅读理解之说明文 (名校期中真题) （22-23高二下·江苏南京·期中）Clothes and covers made of a smart fabric that gives off heat and reflects light could help people and objects that are out in the sun stay several degrees cooler. Guangming Tao at Huazhong University of Science and Technology in Wuhan, China, and his colleagues developed what they call a “metafabric” (超材料织物) by combining microscopic beads (微珠) and fibres, a chemical substance and a type of plastic, all mixed within larger fibres. In one test, a volunteer wearing a vest made half of the metafabric and half of cotton sat in a direct sunlight for an hour. The skin temperature under the metafabric rose from around 31°C to 32 °C over that time, while the skin under the cotton rose to around 37°C． In another test, one car was covered with the metafabric, another with a shop-bought cover and a third was left uncovered. When left in the sun from 11 am to 1 pm, the temperature rose to 60°C in the uncovered car, 57°C in the car with the standard cover and 30°C in the one with the metafabric. The metafabric is most effective when in contact with the skin. The researchers are focusing on cooling people and objects exposed to direct sunlight, but there would still be a cooling effect in the shade. The team has also developed other cooling fabrics that work in a different way. Instead of blocking infrared (红外线), they are transparent to it. One of the main ways that our bodies lose heat is by giving out infrared, so these fabrics could help keep you cool indoors. 1．How do the researchers prove the effectiveness of the smart fabric? A．By listing figures . B．By comparison. C．By listing examples. D．By analyzing causes. 2．Which of the following is TRUE according to the text? A．The car which is covered with the metafabric remains 30 °C in the sun. B．The standard cover is made of the smart fabric-metafabric. C．Guangming Tao discovered a new fabric named “metafabric”. D．The skin temperature under the cotton rose by around 6 °C in one hour. 3．When ma
