[解析]
(1)D.推理判断题。根据第三段""Although the speaking impaired people can't speak,their throats can vibrate (振动) ," Tao told The Paper. "If I put a device made of graphene into the throat of a person,it can detect the vibrations and make sounds using electrical signals.""虽然说话障碍的人不会说话,但他们的喉咙会振动,"陶告诉该报如果我把石墨烯制成的装置放进人的喉咙里,它就能探测到振动,并利用电信号发出声音。"可知人工喉是它根据检测到的振动发出声音让那些说话能力受损的人说话的。故选D。
(2)C.推理判断题。根据第五段""But the speaking impaired people need to classify their own language sounds in groups and memorize them,just like typing keys on a keyboard," Tao said.陶教授说:"但是说话有障碍的人需要将自己的语言声音分组并记忆,就像在键盘上打字一样。"可知有语言障碍的人需要记住他们的声音组才能使用这个设备。故选C。
(3)B.细节理解题。根据第五段"At only the width of an atom (原子),graphene is the thinnest material known to humans and also the strongest.石墨烯只有一个原子的宽度,是人类已知的最薄的材料,也是最坚固的材料。"可知石墨烯它是迄今为止发现的最薄、最坚固的材料。故选B。
(4)A.段落大意题。根据文章倒数第二段"China has emerged as a key country for production.Around 3,000 Chinese companies are exploring uses for graphene,according to government statistics in 2018,while half of the world's graphene﹣related patents (专利) have been filed in China,according to China Daily.(中国已成为重要的生产国。据《中国日报》报道,政府2018年的统计数据显示,约有3000家中国公司正在探索石墨烯的用途,而世界上与石墨烯相关的专利有一半在中国申请。)"可知,倒数第二段主要讲的是石墨烯在中国的潜在广泛应用。故选A项。
