剑桥雅思14 Test3 Passage2阅读答案解析

第14题答案:C

对应原文:C段:Laboratory-based drug discovery has achieved varying levels of success, something which has now prompted the development of new approaches focusing once again on natural products

答案解析:C段开头提到,“以实验室为基础的药品开发取得了不同程度的成功,促使新的开发方法再一次聚焦到自然产品中”。虽然原文中多次提到自然界的医药化合物,但题干中有renewed(再次发生的,再次兴起的)这一限定。只有C段开头能找到对应点(once again),由此确定答案。

第15题答案:H

对应原文:H段:Fortunately, it is now possible to snip out the stretches of the insect’s DNA that carry the codes for the interesting compounds and insert them into cell lines that allow larger quantities to be produced.

答案解析:H段中间提到,“幸运的是,我们如今可以通过提取昆虫搭载化合物的基因片段,然后将它们植入到细胞之中使大量生产成为可能”。其中提取DNA的技术即对应题干中的technological advances,由此确定H为答案。

第16题答案:A

对应原文:A段:such as the capuchin monkeys who rub themselves with toxin-oozing millipedes to deter mosquitoes, or the chimpanzees who use noxious forest plants to rid themselves of intestinal parasites

答案解析:这道题比较简单,哪怕大家不认识capuchin和chimpanzees,也可以通过monkeys与animals的对应确定A为正确答案。

第17题答案:F

对应原文:F段:Firstly, there are so many insects … Secondly, insects are generally very small … Thirdly, Many insect species are infrequently encountered and very difficult to rear in captivity

答案解析:F段给出利用昆虫进行药物研究的三个困难。其一是昆虫数量太多,其二是昆虫太小,其三是许多昆虫很难遇到,并且很难培育。对应题干中的challenging to use insects in drug research,由此确定答案。

第18题答案:I

对应原文:I段:… exploring the useful chemistry of the most diverse animals on the planet, I believe we can make people think differently about the value of nature.

答案解析:这道题需要结合上下文。I段最后提到,“如果我们探索地球上最为多样的生物体内有用的化学物质,我认为我们可以改变人们关于自然价值的看法”。其中最为多样的生物指的就是昆虫,而改变对自然价值的看法则是对应上文中的conservation,也就是benefit wildlife,由此确定答案为I。

第19题答案:B

对应原文:B段:The main cause of this shift is that although there are plenty of promising chemical compounds in nature, finding them is far from easy

答案解析:B段描述了从自然界文章来自老烤鸭雅思到实验室转变的原因,“虽然自然界中有许多有用的化学物质,但找到他们却不容易”。其中shift及对应nature-based medicines fell out of favour,而cause则对应reason,由此锁定答案。

第20题答案:E

对应原文:E段:alloferon, an compound produced by blow fly larvae, is used as an antiviral and antitumor agent in South Korea and Russia.

答案解析:E段提到alloferon的例子,指出这种绿头苍蝇幼虫产生的化合物在韩国和俄罗斯被当作抗病毒药剂和抗癌药剂使用。由此确定答案。

第21题答案:B

对应原文:D段:Consequently … the evolution of an enormous range of very interesting compounds for defensive and offensive purposes.

答案解析:原文中提到了许多昆虫用于药品研究的原因,解题关键在于找到每个选项的对应。A选项错在individual,原文中说的是昆虫整体数量很大,而不是每一种都很多。B选项the variety of对应an enormous range of,substance对应compounds,protect对应defensive,由此确定它为正确答案。

第22题答案:C

对应原文:H段:Fortunately, it is now possible to snip out the stretches of the insect’s DNA that carry the codes for the interesting compounds and insert them into cell lines that allow larger quantities to be produced.

答案解析:这一点在15题已经考察过,应该不难确定C为正确答案。而D选项和E选项则在原文中完全找不到对应,属于无中生有。

第23题答案:ecology

对应原文:G段:My colleagues and I at Aberystwyth University in the UK have developed an approach in which we use our knowledge of ecology as a guide to target our efforts

答案解析:根据大学名称定位到G段的第1句。题干问的是“利用他们在什么方面的专业技能”,其中expertise对应原文中的knowledge,由修饰关系确定ecology为答案。

第24题答案:prey

对应原文:G段:The creatures that particularly interest us are the many insects that secrete powerful poison for subduing prey and keeping it fresh for future consumption.

答案解析:顺着上一题往下,根据interest定位到这一句,preserve与keep fresh同义替换,it代指上文的prey,由此锁定答案。

第25题答案:habitats

对应原文:G段:There are even more insects that are masters of exploiting filthy habitats, such as faeces and carcasses, where they are regularly challenged by thousands of microorganisms.

答案解析:根据microorganisms与bacteria and fungi的对应定位到这句话,从题干in their可以推测空上应该填某个地点,原文中只有habitats填上去语义合适,由此锁定答案。

第26题答案:antibiotics

对应原文:G段:suggesting that there is certainly potential to find many compounds that can serve as or inspire new antibiotics.

答案解析:从题干such as可以看出,空上应该填某种具体的药物,由此锁定antibiotics。
