单选题
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 27 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 28 , and the label says 'pure water'. But maybe what's inside is not so 29 . Would you still be drinking it if you knew that more than 90 percent of all bottled water sold around the world 30 microplastics? That's the conclusion of a recently 31 study, which analysed 259 bottles from 11 brands sold in nine countries, 32 an average of 325 plastic particles per litre of water. These microplastics included a 33 commonly known as PET and widely used in the manufacture of clothing and food and 34 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 35 , 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 36 health risks of drinking water from plastic bottles.

问答题
【正确答案】B
【答案解析】[考点] 动词辨析题。 结构框图: 空格前面有or,说明空格所在部分______ the ruins of Angkor与wandering about in a Thai island构成并列结构。并列结构前后成分要一致,因此本空应填入动词的-ing形式。 本句是在设想出国旅游的情形。空格前面提到,想象你正在泰国的一个小岛上漫步,空格后面应该表示你在“欣赏”或者“游览”吴哥窟废墟。因此,本题答案为B项的admiring。 [参考译文] 出国旅行时,你是买塑料瓶装水还是冒险喝自来水?想象你正在泰国的一个小岛上漫步,或者正在欣赏吴哥窟的废墟。天气太热了,你就从当地小贩那里随手买了一瓶水。这是安全的事情,对吧?瓶子是密封的,标签上写着“纯净水”。然而,瓶子里的水不一定这么天然。如果你知道全世界出售的90%以上的瓶装水中含有塑料微粒,你还会喝吗? 这是最近公布的一项研究的结论,该研究分析了在9个国家出售的11个品牌的259瓶水,发现每升水中平均有325个塑料微粒。这些塑料微粒包括一种通常被称为PET的物质,这种物质被广泛用于制造服装、食品和液体容器。该研究是由纽约州立大学代表奥博媒体(一家新闻机构)进行的。每分钟大约有100万瓶水被购买,购买者不仅有口渴的游客,还有全世界缺乏安全饮用水的21亿人中的许多人。 面对这一证据,包括雀巢、可口可乐在内的几家瓶装水生产商利用同样的方法进行了他们自己的研究。这些研究表明,他们的水中确实含有塑料微粒,但是比奥博媒体研究显示的少得多。无论怎样,世界卫生组织已经发起了一项关于饮用塑料瓶装水的潜在健康风险的审查。
问答题
【正确答案】M
【答案解析】[考点] 语义推断题。 空格前面是系动词is,因此可填入形容词或名词作句子的表语。 本句中的The bottle指上文提到的随手从当地小贩那里买的a bottle of water,由此可以推断,瓶子是密封的、未打开的,故本题答案为M项的sealed。
【答案解析】[考点] 动词辨析题。 分析句子结构可知,空格位于that引导的宾语从句中,这个从句缺少谓语动词,又因为从句主语是more than 90 percent of all bottled water,因此空格处应填入动词的第三人称单数形式。 本句承接上一句,说明瓶装水并不纯净。空格所在宾语从句指出,全世界出售的90%以上的瓶装水中______塑料微粒。因此,空格处应填入含有“包含,含有”意义的动词,故本题答案为C项的contains。备选项中,另外一个动词的第三人称单数形式是N项的solves,填入空格不符合上下文语义,故排除。
问答题
【正确答案】K
【答案解析】[考点] 语义推断题。 空格位于介词短语of a recently ______ study中,前有副词recently,后有名词study,因此应填入形容词或动词的分词形式。 根据常识可知,只有公开了研究结果,人们才能知道研究的结论,因此可推断本空应填入含有“公开,公布”意义的词,故答案为K项的released。备选项中,L项的revealing有“揭示,揭露”的含义,但是study应该是被公开,应用过去分词,故排除L。
问答题
【正确答案】L
【答案解析】[考点] 动词辨析题。 第二段首句的主干是That's the conclusion,其后的which引导非限制性定语从句,修饰study,其后空格所在部分应该是结果状语,表明这项研究的结果,由此推测空格处应填入动词的分词形式。 空格后内容表明,每升水中平均有325个塑料微粒,这应该是该研究的结果,故空格处应填入含有“发现”意义的动词。所以,本题答案为L项的revealing'揭示,揭露”。
