The green movement is not new to fashion, and many designers and manufacturers have been actively seeking out ways to ensure their garments have less of an environmental impact. But what if your clothes were actually able to have a 42 impact on the environment? This vision is one shared by the two founders of Catalytic Clothing(触媒服装): Professor Tony Ryan, a scientist from the University of Sheffield, and Professor Helen Storey, a designer and artist from the London College of Fashion. Together they are working on a project that draws on the growing field of nanotechnology(纳米技术) to create a fabric 43 that can break down pollutants in the air. 'In a sense, it's a recycling of an existing technology that exists in toothpaste and sunscreen,' Professor Storey explains. The additive contains nanoparticles of titanium dioxide which act as a catalyst (触媒剂;催化剂). When light hits these particles, they react with oxygen to make what is essentially a peroxide(过氧化物) bleach. This in turn reacts with air 44 such as nitric oxide and breaks them down. While this technology could be used to create an entirely new fabric, Professor Ryan thinks that it has greater potential as an additive. 'It only needs to be on the surface,' he says. 'You don't 45 it in the fibers, and that means that it's really easy to upgrade existing fabrics with the technology. We think the best way to do this is via the laundry, because everyone washes their clothes.' Jeans have been a particular focus of Catalytic Clothing, both because they are widely prevalent as well as that the particles 46 especially well to cotton denim. And while the amount of air pollutants broken down by any one individual wearing catalyzed jeans is minor, ' 47 , we can have a huge impact on the quality of the air and therefore respiratory health,' Storey says. According to Ryan, 4 people wearing catalyzed jeans in a day would 48 the nitric oxide air pollution created by one car. The future might be one in which this pollution-busting fabric additive is so 49 that we no longer give it a second thought, like fluoride(氟化物) in tap water. Though at the moment it's not commercially 50 , Ryan estimates that it could be with in a year or class. Catalytic Clothing is aiming for mass 51 . The day is near when we'll be able to make our clothes work for us in more ways than one.
问答题
【正确答案】C
【答案解析】根据句子结构可知,空格处缺少一个形容词。上文的...many designers and manufacturers have been actively seeking out ways to ensure their garments have less of an environmental impact与空格所在句子由but连接,由此可推知本句句意应为“但是如果你的服装真的能够给环境带来积极的影响,那又会怎么样?”备选项中的positive“积极的”符合,故选C。
【答案解析】根据句子结构可知,空格处缺少一个动词。as well as连接的前半部分they are widely prevalent“它们广泛流行”是这种添加剂的优点之一,由此可推知后半部分应该也是其优点“这种添加剂颗粒与牛仔裤的棉质布料结合得尤其好”,备选项中的bind“(使)结合”符合句意,故选N。
问答题
【正确答案】B
【答案解析】根据句子结构可知,空格处缺少一个作插入语的副词。由上文的...while the amount of air pollutants broken down by any one individual wearing catalyzed jeans is minor可推知,本句句意应为“穿的人多了就可以极大地影响空气质量”,备选项中的collectively“共同地,全体地”符合句意,故选B。
【答案解析】根据空格前的is so和空格后的that可知,空格处缺少一个形容词。由空格所在句下文中的that we no longer give it a second thought, like fluoride in tap water可推知,如同我们在自来水中使用氟化物一样,这种分解污染的布料添加剂将变得很普遍,备选项中的pervasive“普遍的,无处不在的”符合句意,故选K。
