Unit 1 Great Scientists 李仕才 一、阅读理解。‎ Animals use many tricks to hide from predators(捕食性动物)．While different，they are all visual animals.Now scientists have uncovered a fish species that uses both visual and chemical disguise(伪装)．Rohan Brooker, one of the researchers who made the discovery said that he first thought of the idea after reading about a species which takes on the smell of the plant that it eats.Thus，its predators，ants walk right over it.Since Harlequin Filefish are picky eaters that feed totally off the Acropora—a beautiful species of blue/purple coral，Brooker theorized that they too may be using a similar trick to fool their predators.‎ To test his theory，Brooker's team acquired some filefish from the Great Barrier Reef and divided them into two groups.For the next four weeks，one group fed on their normal diet of the Acropora coral，while the other fed on the Pocillopora coral.In order to test if there was any difference in the way they smelled，the researchers did another experiment.They found the smells from the two groups were different.But there was still a question of whether the smell was strong enough to protect the fish from their natural predators.‎ To test that，Brooker's team added a predatory species of cod(鳕鱼)to the mix.Sure enough，the cod that were placed in the tank containing the fish fed on the Pocillopora coral were immediately able to sense them.In contrast，the cod in the tank where the fish had been fed on their natural diet—the Acropora coral，appeared oblivious to their existence and instead spent much of their time inside the tank's caves.This confirmed the team's suspicion that the filefish have figured out how to give off the smell of the Acropora coral to avoid being detected by predators.‎ While the smellbased disguise had been previously observed in some species of fresh water，this study was the first to prove that the fish's diet was the source of this disguise.Though the theory has only been tested on Harlequin Filefish，Brooker suspects that this kind of chemical disguise is fairly common among sea animals.Sure it gives a whole new meaning to the saying—“You are what you eat！”‎ ‎1．The underlined word “oblivious” in Paragraph 3 may mean “________”．‎ A．ignorant B．sensitive C．allergic D．cautious 8‎ ‎2．What statement may Brooker agree to?‎ A．Freshwater fish all know the role of smell.‎ B．Sea animals use smell to cheat their enemies.‎ C．The smellbased disguise may work occasionally.‎ D．Humans are really what kind of fish they eat.‎ ‎3．What is the passage mainly about?‎ A．A way to fight against predators.‎ B．A smell trick of all sea animals.‎ C．A fish smells like the coral.‎ D．Filefish in the Great Barrier Reef.‎ ‎【解题导语】本文是一篇说明文，主要介绍了一项关于Harlequin Filefish如何通过自身的伪装来抵御捕食性动物的研究。‎ ‎【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。‎ ‎1．A　考查词义猜测。根据该词前面的描述及后面的“and instead spent much of their time inside the tank's 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”。‎ ‎2．B　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 disguise 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 saying—‘You are what you eat！’”可知，该句中的“You”指的不是人类，故排除D。‎ ‎3．A　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 similar 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。‎ 8‎ 二、语法填空。‎ China will allow all couples to have two children，__1__ (give) up its decadeslong onechild policy, the Communist Party of China (CPC) __2__ (announce) after a key meeting on Thursday.‎ The change of policy is intended to balance population development and meet the challenge of an aging population, according to a communiqué (公报)__3__ (issue) after the Fifth Plenary Session of the 18th Communist Party of China (CPC) Central Committee held from Monday to Thursday.‎ The proposal must be approved by the top legislature (立法机关) __4__ it comes into force.‎ China‎'s family planning policy was first introduced in the late 1970s __5__ (control) the rapid __6__ (grow) of the population by limiting most urban couples __7__ one child, and as to rural couples, they can have two children on condition that their firstborn child was a girl.

When one has babies, it makes national news __1__， and pictures of their babies are __2__ circulated. But it now seems that the giant panda is not __3__ of itself.‎ The lovely animals have __4__ a classic test of selfawareness. They cannot __5__ themselves in the mirror.

Human children often pass the test when they are only two years old.‎ Many other animals have passed the mirror test, including monkeys, Asian elephants and even pigeons. But when researchers tested pandas, __12__ of them did the same thing as those animals did. __13__， each panda behaved as if their __14__ in the mirror was another panda altogether. They acted as if they were __15__ by what they saw in the mirror, scratching their feet and walking __16__.‎ The __17__ of this research will help design better areas for animals in captivity (圈养). For example, onedirectional glass sometimes used in the areas may __18__ pandas to feel stressed when they see their own image in the __19__. That's because they might believe it to be another panda, __20__ themselves.‎ ‎1．A.papers　　　　　B．covers C．headlines D．pages ‎2．A.widely B．popularly ‎ C．especially D．completely ‎3．A.shy B．fond C．conscious D．confident ‎4．A.failed B．ignored 8‎ C．faced D．conducted ‎5．A.observe B．discover C．recognize D．understand ‎6．A.believe in B．find out C．pick out D．take in ‎7．A.sense B．question C．opinion D．thought ‎8．A.for B．with C．in D．before ‎9．A.how B．when C．why D．whether ‎10．A.touchable B．seeable C．sensible D．possible ‎11．A.dismisses B．admits C．feels D．moves ‎12．A.all B．most C．one D．none ‎13．A.Thus B．However C．Instead D．Still ‎14．A.reaction B．reflection C．operation D．imagination ‎15．A.trapped B．amazed C．threatened D．teased ‎16．A.backwards B．alone C．forwards D．along ‎17．A.failure B．outcome C．success D．review ‎18．A.cause B．prepare C．accelerate D．urge ‎19．A.eyes B．cages C．zoo D．glass ‎20．A.other than B．regardless of C．because of D．rather than 8‎ ‎【解题导语】本文是一篇说明文。本文对大熊猫、儿童还有其他的动物都做了有关自我意识感方面的研究，结果显示大熊猫的自我认知很差，即使照镜子，它们也认不出镜子里的自己。‎ ‎1．C　考查名词辨析。根据上文中的“and know that they are endangered”可推知，当一个大熊猫有宝宝后，很快就会上国内新闻头条。C项意为“头条(新闻)”，符合语境。A项意为“报纸”；B项意为“封面”；D项意为“页码”，均与语境不符。故选C项。‎ ‎2．A　考查副词辨析。上文提到，当一个大熊猫有宝宝后，很快就会上国内新闻头条；由此可推知，大熊猫宝宝的照片会被广泛传阅。A项意为“广泛地”，符合语境。B项意为“流行地”；C项意为“特别地”；D项意为“完全地”，均与语境不符。故选A项。‎ ‎3．C　考查形容词辨析。根据第二段第一句中的“a classic test of selfawareness”可知，这里指的是现在看起来大熊猫是没有自我意识的。C项意为“有意识的”，符合语境。A项意为“害羞的”；B项意为“喜欢的”；D项意为“自信的”，均与语境不符。故选C项。‎ ‎4．A　考查动词辨析。根据下文中的“They cannot... have a ________ of selfawareness.”可知，可爱的大熊猫没有通过这种经典的自我意识测试。A项意为“失败”，符合语境。B项意为“忽视”；C项意为“面对”；D项意为“指挥，引导”，均与语境不符。故选A项。‎ ‎5．C　考查动词辨析。根据下文的“Researchers use the mirror recognition...”可知，此处指大熊猫认不出镜子中的自己。C项意为“辨认出”，符合语境。A项意为“观察”；B项意为“发现”；D项意为“理解”，均与语境不符。故选C项。‎ ‎6．B　考查动词短语辨析。根据语境可知，此处指研究者的目的是弄清楚孩子或动物是否有自我认知。B项意为“找到，弄清楚”，符合语境。A项意为“相信，信任”；C项意为“挑选出”；D项意为“吸收，欺骗”，均与语境不符。故选B项。‎ ‎7．A　考查名词辨析。根据语境可知，此处指自我认知，是一种感觉。A项意为“感觉”，a sense of为固定搭配，意为“一种……感”，符合语境。B项意为“问题”；C项意为“观点”；D项意为“想法”，均与语境不符。故选A项。‎ ‎8．B　考查介词辨析。根据语境可知，此处指在实验中，动物在镜子中呈现出来。表示使用某种工具，应用介词with。‎ ‎9．D　考查连词辨析。根据语境可知，此处指研究者想观察大熊猫是否能注意到它脸上的记号。故选D项。‎ ‎10．B　考查形容词辨析。根据常识可知，在自己脸上的标记，只有在镜子中才能看到。B项意为“可见的”，符合语境。A项意为“可触摸的”；C项意为“可觉察的”；D项意为“可能的”，均与语境不符。故选B项。‎ ‎11．C　考查动词辨析。根据下文的“Many other animals have passed the mirror 8‎ ‎ test”可知，此处指如果动物注意到脸上的标记，它会感受到这个标记的。C项意为“感受，感觉”，符合语境。A项意为“解雇，解散”；B项意为“承认”；D项意为“移动”，均与语境不符。故选C项。‎ ‎12．D　考查代词辨析。根据上文及转折词“but”可知，此处指没有一只大熊猫像其他动物一样能感受到脸上的标记。故选D项。‎ ‎13．C　考查副词辨析。根据语境可知，此处指“相反，每一只大熊猫表现得就像镜子里的影像是其他大熊猫”。C项意为“代替，而不是”，符合语境。A项意为“因此”；B项意为“然而”；D项意为“仍然”，均与语境不符。故选C项。‎ ‎14．B　考查名词辨析。根据常识可知，镜子中应是映照出的影像。B项意为“映像，倒影”，符合语境。A项意为“反应”；C项意为“操作，手术”；D项意为“想象”。均与语境不符。故选B项。‎ ‎15．C　考查动词辨析。根据下文中熊猫的反应可知，熊猫表现出好像受到镜子中“自己”的威胁。C项意为“威胁”，符合语境。A项意为“使陷入困境，卡住”；B项意为“使惊讶”；D项意为“取笑，戏弄”，均与语境不符。故选C项。‎ ‎16．A　考查副词辨析。根据常识可知，害怕会向后退。A项意为“向后”，符合语境。B项意为“独自地”；C项意为“向前”；D项意为“一起，沿着”，均与语境不符。故选A项。‎ ‎17．B　考查名词辨析。根据语境可知，此处指研究的结果。B项意为“结果”，符合语境。A项意为“失败”；C项意为“成功”；D项意为“复习”，均与语境不符。故选B项。‎ ‎18．A　考查动词辨析。由语境可知，此处指可以成像的玻璃会让大熊猫感到有压力。cause sb. to do sth. 意为“导致某人做某事”，符合语境。B项意为“准备”；C项意为“加速”；D项意为“督促”，均与语境不符。故选A项。‎ ‎19．D　考查名词辨析。根据上文中的“onedirectional glass”可知，glass符合语境。故选D项。‎ ‎20．D　考查介词短语辨析。由语境可知，此处指这就是因为大熊猫相信镜子里是别的大熊猫而不是自己。D项意为“而不是”，符合语境。A项意为“除了”；B项意为“不管”；C项意为“因为”，均与语境不符。故选D项。‎ 四、短文改错。‎ One day, an old man was returning home after shopping.
