[解析]
(1)C.推理判断题。根据第一段Captured(捕获的)carbon dioxide(CO2)could be used to extract(提炼)useful metals(金属)from recycled technology such as smartphone batteries rather than just being buried underground.(捕获的二氧化碳可用于从智能手机电池等回收技术中提取有用的金属,而不仅仅是埋在地下。)可知,废弃的智能手机电池以前可能埋在地下,故选C.
(2)A.细节理解题。根据第三段CO2 is the main cause of modern climate change,so many people have attempted to develop technologies to capture it when it comes from power plants and other major sources.(二氧化碳是现代气候变化的主要原因,因此许多人试图开发技术来捕获来自发电厂和其他主要来源的二氧化碳)可知,很多人试图捕获二氧化碳,因为二氧化碳是现代气候变化的主要原因,故选A.
(3)B.细节理解题。根据倒数第二段中的This is normally done using highly reactive chemicals,which are potentially polluting.Replacing them with CO2should lead to a much lower environmental pollution,he says.(这通常是通过使用高活性的化学物质来实现的,这些化学物质具有潜在的污染,他说用二氧化碳取代它们应该会大大降低环境污染)可知,该团队的办法将会极大的减少环境污染,故选B.
(4)D.标题归纳题。根据第一段Captured(捕获的)carbon dioxide(CO2)could be used to extract(提炼)useful metals(金属)from recycled technology such as smartphone batteries rather than just being buried underground.The technique could help make it more economical to capture the greenhouse gas before it enters the atmosphere.(捕获的二氧化碳可用于从回收技术(如智能手机电池)中提取有用的金属,而不仅仅是埋在地下。这项技术有助于在温室气体进入大气层之前更经济地捕获它们)可知,文章主要讲述了法国里昂大学Leclaire和他的团队发现了捕捉到的二氧化碳的一个用处就是区分金属混合物,使得回收电池和其他设备更环保,大大降低环境污染。选项D.Captured CO2Could Be Used to Help Recycle Useful Metals﹣捕获的二氧化碳可以用来帮助回收有用的金属,符合文意,故选D.
