10、性动物的研究。【难句分析】Though the theory has only been tested on Harlequin Filefish，Brooker suspects that this kind of chemical disguise is fairly common among sea animals.分析：本句包含 Though 引导的让步状语从句；that 引导宾语从句。译文：尽管这个理论只在 Harlequin Filefish 身上得到验证，但 Brooker 猜想这种类型的化学伪装在海洋动物身上是相当普遍的。1A 考查词义猜测。根据该词前面的描述及后面的“and

11、instead spent much of their time inside the tanks caves”可知，此处为这些鳕鱼对于以 the Acropora coral 为食的鱼的存在看起来是不知道的。ignorant“不知道的，愚昧的” ；sensitive“敏感的” ；allergic“过敏的” ；cautious“谨慎的” 。2B 考查推理判断。根据最后一段第二句“Though the theory has only been tested on Harlequin Filefish，Brooker suspects that this kind of chemical disg

12、uise is fairly common among sea animals”可知，Brooker 赞同的是海洋动物通过气味来欺骗它们的敌人。根据最后一段第一句中的“While the smellbased.in some species of fresh water”可排除 A；根据最后一段第二句中的“Brooker suspects that this kind of chemical disguise is fairly common among sea animals”可排除 C；根据最后一段第三句“Sure it gives a whole new meaning to the s

13、ayingYou are what you eat！ ”可知，该句中的“You”指的不是人类，故排除 D。3A 考查主旨大意。根据第一段中的“Animals use many tricks to hide from predators(捕食性动物)”和“Brooker theorized that they too may be using a 3similar trick to fool their predators”可知，本文主要介绍了抵御捕食性动物的一种方法，故 A 项符合题意。二、语法填空。China will allow all couples to have two childr
