We don’t know why, but it is just pleasant to us.”(你是否曾经有过一种冲动,打开一本书,然后把鼻子直接贴在书页上 旧书的气味能让任何一个书迷精神振奋。我们不知道为什么,但这对我们来说很愉快。)可知,第一段描述了我们迷恋书籍气味的现象。故选D项。 2.A　细节理解题。根据第三段“‘You tend to use familiar associations to describe smells when they are unlabeled,’ study author Cecilia Bembibre says.”(研究的作者Cecilia Bembibre说:“当气味没有标签时,你倾向于联想熟悉的事物来描述它们。”)及第三段全段内容可知,人们在描述未知气味时,倾向于联想熟悉的事物。故选A项。 3.A　推理判断题。根据第四段“Using the data from the chemical analysis and visitors’ smell descriptions, the researchers created the Historic Book Odor Wheel to document the ‘historic library smell’. Main categories such as ‘sweet/spicy’ fill the inner circle of the wheel; descriptors such as ‘chocolate/cream’ fill the middle; and the chemical compounds likely to be the smelly source, like furfural, fill the outer circle.”(利用化学分析的数据和游客对气味的描述,研究人员创建了“历史图书气味轮”来记录“历史图书馆的气味”。主要类别,如“甜/辣”,填满了轮子的内圈;描述词,如“巧克力/奶油”,填充在中间;而可能是难闻气味来源的化合物,如糠醛,则填满了外层。)可推知,“历史图书气味轮”的功能应是描述气味。故选A项。 4.C　推理判断题。根据最后一段“The researchers want the book odor wheel to be a tool that ‘untrained noses’ can use to identify smells and the compounds causing them, which could address conservators’ concerns about material composition and historic paper conservation. And hopefully, smells of the past can be reproduced in the lab someday and museums and historians can use it to reconstruct a past we can no longer smell.”(研究人员希望这个图书气味轮能成为一种工具,未经训练的人可以用它来识别气味和产生气味的化合物,这可以解决文物保护人员对材料组成和历史纸张保护的担忧。希望有一天,过去的气味可以在实验室里重现,博物馆和历史学家可以用它来重建我们再也闻不到的过去。)可推知,研究者们未来有望利用气味轮来保护历史材料文献,重现过去的气味。故选 C项。 Ⅴ.【文章大意】 这是一篇说明文。文章介绍了AR和VR的相同点和不同点。 1.G　根据上文“In a world where technology is king, hardly does a day go by without the launch of some ‘world-changing’ product in the field of alternate reality.”(在一个 ... ...
