1、小马过河GRE阅读经典文章解析小马过河国际教育 摘要：GRE阅读经典文章解析。下面是一篇GRE阅读经典的短文章实例，考生可以先做一下，然后对照答案并参照名师的点评分析来提高GRE考试成绩。 Ingestion of food containing spores of the pathogen Ascosphaera apis causes a fatal fungal disease known as chalk brood in honeybee larvae. However, larvae must be chilled to about 30C (normal brood-comb t
2、emperature is 33-36C) for the disease to develop. Accordingly, chalk brood is most common in spring and in small colonies. A recent study revealed that honeybees responsible for hive-temperature maintenance purposely raised the hives temperature when colonies were inoculated with A.apis. this “fever
3、,” or up-regulation of temperature, occurred before any larvae died, suggesting that the response is preventative and that either honeybee workers detect the infection before symptoms are visible or larvae communicate the ingestion of the pathogen. Temperature returned to normal by the end of the st
4、udy, suggesting that increased temperature is not optimal when broods are not infected, as well as that the fever does not result merely from normal colony growth (i.e., an increase in the number of workers available for temperature maintenance). 24. The primary purpose of the passage is to (A) disc
5、uss the findings and implications of a particular study (B) illustrate a process that formerly had been misunderstood (C) outline the methods used to investigate a problem (D) provide evidence to support a controversial theory (E) contrast alternative interpretations of certain date 25. According to
6、 the passage, researchers concluded that fever in honeybee colonies ispreventative because their study showed that such fever (这题多数同学选的C. 问的是为什么研究人员认为发热是保护行为) (A) does not occur when hive temperatures are within normal range 该行为不发生在蜂房温度正常的情况下.(应该非常好排除吧,升温和蜂房原来温度无关,只有感染了才会升) 小马过河国际教育 (B) protests adu
7、lt bees from contracting chalk brood infection 防止成年蜜蜂接触感染.(升温的作用是防止发作,文章中没有提到是否能隔绝传染. ) (C) occurs prior to the death of any larvae 在任何幼虫死亡之前发生. (文中原话,虽然直接得有点让人不敢选,但是确实是最佳答案.) (D) is more likely to occur in spring than in summer 相较于在夏天,更可能在春天发生. (than是GRE阅读中需要引起注意的词.文中没有明确指出,不如C来得更直接,而且有点答非所问.) (E)
8、does not have an effect on uninfected broods 对于没有感染的蜜蜂没有影响.(答非所问). 26. The passage implies that if hive temperature had not returned to normal by the end of the study in question, a probable conclusion of the researchers would have been that (这题牵涉到对文章最后一句的理解,只要取反就可以了.所以我觉得是B,这题争议比较严重.其实最后一句的意思就是最终的实
9、验结果(温度回归)说明暂时升高的 温度不是蜂群的最爱-说明是不得以而为之;而后半句温度升高不仅仅是蜜蜂数量的增多,说明热量不是数量上升累积的结果而是有别的什么因素促成.换而言 之还是说明了温度升高是有意识地保护行为.所以回答这题的时候把这两点的想法取反就OK了) (A) up-regulation of temperature is a preventative measure against chalk brood 说明升温是保护性措施. (和上述说法取反后不同吧.) (B) honeybees are incapable of purposely raising hive temperat
10、ures 蜜蜂不能有意识地升高蜂房温度. (正确,符合上述第二个说法取反的结果). (C) A. apis cannot be completely eradicated through up-regulation of temperature along 说明仅仅通过升温A不能完全被消除. (到底A有没有被消除实验没有说吧.) (D) honeybee larvae have a mechanism to alert adult honeybees to the presence of A. apis 幼虫有能力向成年蜜蜂报警. (完全没关系的回答吧.) (E) honeybee larva
11、e may benefit from increased hive temperature even when there is no A. apis present 即使没有A,幼虫可能从增高的温度中获益. (这个推测过远了吧,如果温度没降下也不能说明幼虫可能获益吧,相较于E,B更加合适吧.) 27. According to the passage, which of the following is true of chalk brood infection among honeybee larvae? (这题争议同样比较严重,我倾向于选D. 问的是下列关于感染的选项中哪个是符合文章意思
12、的.) (A) Larvae in small colonies are more likely to pass the infection to adult honeybees than are larvae in large ones. 相较于大蜂群,小蜂群中的幼虫更容易把感染传给成年蜂(文章中根本没说病毒传染的问题吧). 小马过河国际教育 (B) Infection with chalk brood induces larvae to raise their hives temperature. 感染使得幼虫升高蜂房的温度. (这是成年蜜蜂干的活吧.) (C) The infection
13、 is more likely to affect larvae in winter than in spring. 相比于春天,感染更容易在冬天发生.(虽然冬天看上去温度低,但是文章说是春天,我们不能以自己先入为主的来做题.) (D) Larvae fail to develop symptoms of the disease when their brood comb temperature remains within the normal range. 在蜂群温度正常的时候幼虫身上没有任何感染的病症.(文章中说到过在病症出来之前成年蜂就开始增加蜂房的温度了,说明没出病症的时候蜂房温度是正常的.) (E) Infected larvae exhibit visible symptoms of disease for a significant time before death. 被感染的幼虫在死前会有相当长的一段时间表现出可见的病症. (a significant time 完全臆测). 以上即是备考GRE阅读的经典短文章实例，大家在做GRE阅读文章时，可以按照以上所提到的备考GRE阅读技巧进行实战练习，从而取得理想的GRE考试成绩。 本文转载自小马过河国际教育
