问题    When travelling overseas, do you buy water in plastic bottles or take your chances with tap water? Imagine you are wandering about on a Thai island or【C1】______the ruins of Angkor. It’s hot so you grab a bottle of water from a local vendor. It’s the safe thing to do, right? The bottle is【C2】______, and the label says "pure water". But maybe what’s inside is not so【C3】______Would you still be drinking it if you knew that more than 90 percent of all bottled water sold around the world【C4】______microplastics?
   That’s the conclusion of a recently【C5】______study, which analysed 259 bottles from 11 brands sold in nine countries,【C6】______an average of 325 plastic particles per litre of water. These microplastics included a【C7】______commonly known as PET and widely used in the manufacture of clothing and food and【C8】______containers. The study was conducted at the State University of New York on behalf of Orb Media, a journalism organisation. About a million bottles are bought every minute, not only by thirsty tourists but also by many of the 2.1 billion worldwide who live with unsafe drinking water.
   Confronted with this【C9】______, several bottled-water manufacturers including Nestle and Coca-Cola undertook their own studies using the same methodology. These studies showed that their water did contain microplastics, but far less than the Orb study suggested. Regardless, the World Health Organisation has launched a review into the【C10】______health risks of drinking water from plastic bottles.
   A) adequate F) instant K) released
   B) admiring G) liquid L) revealing
   C) contains H) modified M) sealed
   D) defending I) natural N) solves
   E) evidence J) potential O) substance
【C10】
选项
答案J
解析 [语法判断]空格前有定冠词the，后面有名词，因此应填入形容词。[语义判断]空格所在句前一句提到，瓶装水生产商自己的研究发现，他们的水中含有的塑料微粒比奥博媒体的研究发现的要少得多。但是无论多少，水中的塑料微粒对人体健康都是有害的，因此世界卫生组织发起这项审查，不过目前风险还不明确，因此本空应填入含有“潜在的，隐藏的”意义的形容词，故本题答案为J)potential。
