(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)
(B) protests adult 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) 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 temperatures 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).(第二种说法是说升温不是种群自然增大的结果，如果取反也不是这个吧)
(C) A. apis cannot be completely eradicated throughup-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 presenceof 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 larvae 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.)(我觉得这正是第一种说法的取反啊)
27. According to the passage, which of the following is true of chalk broodinfection 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).
(B) Infection with chalk brood induces larvae to raise their hive’s 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 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).
对于倒数第二题有争议，3.Temperature returned to normal by the end of the study, suggesting thatincreased temperature is not optimal when broods are not infected, as well as that the fever does not result merely from normal colony growth。。。那么好了，如果像题干所说，温度不下降的话，根据文中只能推出两个可能的答案：1. it is an optimal when broods are not infected. 2 the fever does result merely from normal colony growth. 看选项，E完全符合。至于楼主选的B选项，文中有明确的表示：从第四行开始看起： a recent study reveled that ....purposely raised the hives' temperature...所以B明显是错的，D和题目无关，AC选项都是和最后一句话的内容无关。
