第一篇： 保持年轻的秘密

错题一

Behaviour:
how _____ they attacked prey

答案： aggressively好斗的；挑衅的

原文： And when it came to reacting to prey, the older ants attacked the poor fruit fly just as aggressively as the young ones did,

错误的原文： And she experimented with how ants react to live prey
这里很容易引起混淆。

解析： 定位词：attacked, prey

对应第四段第四句至段末And she experimented with how ants react. …as aggressively as the young ones did…

第四段后半部分重点讲述了有关蚂蚁对食物的反应的研究：she experimented with how ants react to live prey。本段最后一句提到在对食物的反应方面，年龄更大的蚂蚁和年幼的蚂蚁一样 aggressively，因此本题答案为aggressively。

错题二

Pheidole dentata ants are the only known animals which remain active for almost their whole lives.

参考译文：Pheidole dentata 蚂蚁是已知仅有的在整个生命中保持活力的动物。

定位词：Pheidole dentata ants

对应第二段前三句：Such age-defying feats … never get cancer.第二段开头说到，Such age-defying feats are rare in the animal kingdom，之后在第二、三句举了naked mole rats的例子，这就说明尽管非常少见，但Pheidole dentata ants并不是已知仅有的具有这种能力的动物。因此本题答案为FALSE。

第二篇： 为什么动物园是好的

错题一

Studying animals in zoos is less stressful for the animals than studying them in the wild.

答案：NG

生词： excelled at 擅长；胜过平时

第三篇： 海洋垃圾的威胁

错题一

Rochman and her colleagues were the first people to research the problem of marine debris.
答案： False

参考译文：Rochman和她的同事是最先研究海洋废弃物问题的人。

定位词：Rochman and her colleagues

第二段第二句：Plenty of studies have…how many of those perceived risks are real.

文中第二段第二句说到Plenty of studies have sounded alarm bells about the state of marine debris，而后全文都涉及了之前的研究者对这一课题的研究，因此Rochman和她的同事们不是最先研究这一课题的人。

因此本题答案为FALSE。

错题二

Most of the research analysed by Rochman and her colleagues was badly designed.
答案：F

参考译文：Rochman和同事们分析的大多数研究都设计得有问题。

定位词：Most of the research

第五段：In 83 percent of cases, the perceived dangers…or used faulty statistics.

文中第五段对Rochman分析的论文情况进行了说明，其中在83%的案例中，海洋垃圾的潜在危险被证明是真实的，在剩余的案例中，工作组发现这些研究在设计和内容方面存在缺陷，这些缺陷影响了研究结论的有效性。这与题目中的“大多数研究都设计得有问题”不一致。

因此本题答案为FALSE。

错题三

One study examined by Rochman was expecting to find that mussels were harmed by eating plastic.
答案： T

参考译文：Rochman 分析的一项研究预期发现贻贝受到了误食塑料的危害。

定位词：One study examined by Rochman

第六段：Strikingly, Rochman says, only one well-designed study…didn’t seem to stress out the shellfish.

文中第六段说到，只有一项设计完善的研究没有发现它预期的影响，这是一项有关贻贝误食微小塑料碎片的调查。科学家发现，塑料从贻贝的胃部移动到血液中，并在那里停留了几个星期——但似乎并没有使这一甲壳类动物受到损伤。这与题目中的表述一致。

因此本题答案为TRUE。

错题四

bits of debris that were ____ (harmful to animals)

答案： large

定位词：metal, wood, bits

第八段第二句：Most of the dangers also involved…or eating it and severely injuring themselves.本题可以根据上一行的plastic (not metal or wood)帮助确认答题区域，然后将题目与第八段第二句进行对应，原文中large pieces of debris与题目对应。因此本题答案为large。

错题五

There was little research into ____e.g. from synthetic fibres.
答案： microplastic

定位词：ittle research, synthetic fibers

第九段第二句：These maybe ingredients used in cosmetics and toiletries, fibers shed by synthetic clothing in the wash, or eroded remnants of larger debris.根据题目中的定位词，可以在第九段找到对应的句子，其中第一句提到的microplastic是这部分描写的重点，而文中的fibers shed by synthetic clothing也与题目信息对应。因此本题答案为microplastic。

错题六

Rochman says more information is needed on the possible impact of future ____ (e.g. involving oil).

答案： disasters
定位词：future, oil

第十一段第二句：Usually, scientists don’t know exactly…until after they’ve happened.文中第十一段写到，通常，对于游轮意外地泄露整船石油并污染大片海洋这类事件，科学家们直到事情发生才能准确地知道灾难对环境产生的影响，与题目表述一致，因此本题答案为disasters。

错误原因： 这里有一个长难句
scientists don’t know exactly how disasters such as a tanker accidentally spilling its whole cargo of oil and polluting huge areas of the ocean will affect the environment until after they’ve happened.
应该把不相关的内容去掉，去掉之后变成了这样
scientists don’t know exactly how disasters will affect the environment until after they’ve happened.
科学家们不知道灾难是如何影响环境的，直到它发生以后。

错题七

The studies Rochman has reviewed have already proved that populations of some birds will soon become extinct.
答案：F

参考译文：Rochman分析的研究已经证明些鸟类很快会灭绝。

定位词：The studies Rochman has reviewed

第三段第三句：‘But the truth was that nobody had yet tested those perceived threats,’Rochman says. ‘There wasn’t a lot of information.’

文中第三段第二、三句说到，例如，一份研究可以说明某种海鸟误食塑料袋，并进而警示人们整个鸟群都可能面临灭绝。“但事实是没有人验证过这些潜在的威胁，”Rochman说。因此从第三段的信息可知，实际上之前的研究并没有proved that populations of some birds will soon become extinct，这与题目表述相反。

因此本题答案为FALSE。

生词：
cargo (船或飞机装载的)货物
entangled 使纠缠；使卷入；缠住；使陷入；套住
dismal 惨淡的
bothersome 引起麻烦的；困扰人的
