课时分层作业(十二) Ⅰ.阅读理解(限时7分钟) (2022·石家庄市高中毕业班诊断性联考) Scientists in Australia have discovered that they can use the world's smelliest fruits to make devices that could power electric cars.A durian(榴梿) is a fruit that looks like a pineapple.It is a delicacy(佳肴) in some Asian countries，but its smell is so unpleasant that some of those countries have banned it from public places.Its smell has been compared to rotten eggs and even smelly old gym socks. Vincent Gomes and his colleagues at The University of Sydney，in Australia，used durians and jackfruits—another fruit known for its terrible smell—to make energy­storing devices called supercapacitors. Supercapacitors are an alternative to batteries.They can't store as much energy as a normal battery does，but they are much quicker to recharge.Durians and jackfruits contain some of the chemicals used in supercapacitors，which gave Gomes the idea.To make the fruit­based devices，the team heated and then freeze­dried the uneatable cores of the durian and the jackfruit to make a special kind of material called an aerogel. Aerogels are one of the world's lightest solid materials.Often called “frozen smoke”，they are made by removing the liquid from a gel (胶状物) and replacing it with air.They have many scientific uses，and one of their special properties is the ability to conduct electric currents，which makes them an important part of supercapacitors.The aerogels made from durians and jackfruits both worked well when placed inside a supercapacitor，although the durian aerogel was found to be the better of the two. The discovery is important because the materials currently used to make supercapacitors are expensive.Using natural foods like durians and jackfruits，Gomes says，could reduce environmental pollution as well as costs. 【语篇解读】　 本文是一篇新闻报道。本文讲述了澳大利亚的科学家用榴梿和菠罗蜜制造出了存储能量的设备——超级电容器。 1．What makes some countries have different attitudes towards the durian?
