British chemist David Evans has become an overnight celebrity on Chinese social media. His chemistry experiments have attracted over 2 million followers in just a few months. Evans is a chemistry professor at the Beijing University of Chemical Technology. The 60-year-old always wears a white lab coat, a pair of safety goggles (护目镜), and smiles often. Some web users say he looks just like the “grandpa of KFC”.

Evans has posted videos of various experiments. His most popular experiments have attracted millions of hits on video-sharing apps. Excited children’s cheers and shouts can be heard in his videos. “I hope my experiments can arouse people’s interest in science,” he says.

Evans has been interested in China since childhood. In the early 1970s, before the reform and opening-up, he viewed it as a “country full of mysteries”. He first visited the Chinese mainland in 1987 to attend a chemistry conference in Nanjing, Jiangsu Province. He quit his job in the United Kingdom and moved to Beijing in 1996. Many of his friends thought he was crazy. But Evans says they just saw China’s challenges but not its potential.

Since 2011, Evans has turned to the Internet to popularize science. He learned short-video apps are also popular in small cities and rural areas. And he realized this enables him to reach more students, who lack opportunities to perform fun experiments. But even a one-minute video requires a considerable amount of work. Still, he thinks it’s worth it to fulfill his responsibility to popularize science.

His experiments always fill schools’ lecture halls with laughter. Some viewers call him “a Harry Potter-like magician”, but he disagrees. “A magician never tells the secrets behind his tricks, but a scientist always gives an explanation.” He sees himself as a teacher. He performs experiments to spread knowledge, inspire thinking, remove misunderstandings and show that science can create change. Evans says he looks forward to more “chemical reactions” with China.

1. C 2. D 3. A 4. B 【解析】 这是一篇说明文。主要介绍了一位移居中国,并在网上发布化学实验短视频的英国化学家David Evans在中国的一些事迹。 1.细节理解题。第一段第三句“Evans is a chemistry professor at the Beijing University of Chemical Technology.”可知埃文斯是北京化工大学的化学教授。故选C。 2.主旨大意题。根据第三段第二句“He first visited the Chinese mainland in 1987 to attend a chemistry conference in Nanjing, Jiangsu Province.”可知埃文斯第一次访问中国大陆是在1987年,当时他要去江苏省南京市参加一个化学会议。故第三段讲述了埃文斯1987年来中国去江苏南京开会的事情,故D选项符合题意。 3.细节理解题。第四段第一句“Still, he thinks it’s worth it to fulfill his responsibility to popularize science.”可知,尽管要付出巨大工作量,埃文斯仍然认为履行普及科学的责任是值得的。因此可知埃文斯在网上发布小视频的原因是为了普及科学,故选A。 4.推理判断题。根据最后一段最后一句“Evans says he looks forward to more “chemical reactions” with China.”可知,埃文斯期待与中国进行更多的“化学反应”。因此不管外界反应如何,他都将继续在中国发布实验视频,故选B。
