If your family are not sure what colour car to choose, the magical colour-changing car may be a good choice. A German car company showed its new colour-changing car at the Consumer Electronics Show held in the US.
The colour-changing paint technology mainly depends on E Ink(电子墨水). E Ink is widely used in e-readers. With E Ink, people can change the car's colour simply with the touch of a button. At first, the colours were limited to white, black and grey, but now the car can take on over thirty different colours.
We all know that a white surface reflects a lot more sunlight than a black one. On hot sunny days, more sunlight is reflected down in the cooler weather. If the car is turned into a light colour, like white, more sunlight is reflected down. If the car is turned into a darker skin, it will help take in more heat from the sun. In both cases, colour changes help cut the energy use for the air conditioner, too. Unlike the technology itself, it uses energy only to change colours. No energy is needed to keep the chosen colour staying there.
Adrian van Hooydonk, the designer director of the car, says, "The colour-changing is a great example of our forward thinking."

答案
20.B 21.D 22.C 23.A
B篇
本文是一篇说明文，介绍了德国某汽车公司推出的变色汽车，涵盖其技术原理(电子墨水)、颜色变化的功能及节能特点。
第21题:主旨大意题
解析:第三段通过“浅色反射阳光、深色吸收热量”的例子，说明变色汽车调整颜色能减少空调能耗，核心是“变色如何帮助节能”。
答案:D
第23题:推理判断题
解析:A正确:原文“At first, the colours were limited to white, black and grey”表明初期只有3种颜色;B错误:原文是“with the touch of a button”(需按按钮才能变色);C错误:新车是在美国的消费电子展上展示，并非德国;D错误:原文明确“保持选定颜色不需要能量”。
答案:A

解析
【分析】
本题为英语阅读理解题，需通过定位原文信息、分析段落主旨、对比选项与原文细节来解答。20题是细节理解题，需查找变色汽车的来源；21题是主旨大意题，需概括第三段核心内容；22题是细节理解题，需结合夏天的需求匹配对应颜色；23题是推理判断题，需逐一核对选项与原文表述是否一致。
【解析】
20. 细节理解题：根据题干关键词“new colour-changing car come from”，定位到原文第一段第二句“A German car company showed its new colour-changing car at the Consumer Electronics Show held in the US.”，可知变色汽车来自德国，故选B。
21. 主旨大意题：第三段主要阐述浅色（如白色）反射更多阳光、深色吸收更多热量，最终目的是帮助减少空调能耗，核心是变色汽车如何节能，故选D。
22. 细节理解题：根据题干“in summer”，结合原文第三段“On hot sunny days...If the car is turned into a light colour, like white, more sunlight is reflected down”，夏天需反射更多阳光，应选白色，故选C。
23. 推理判断题：A选项对应原文“At first, the colours were limited to white, black and grey”，初期仅三种颜色，正确；B选项原文为“with the touch of a button”，需按按钮变色，错误；C选项新车是在美国消费电子展展示，并非德国，错误；D选项原文明确“保持选定颜色不需要能量”，错误，故选A。
【答案】
20.B 21.D 22.C 23.A
