         (D) honeybee larvae have a mechanism to alert adult honeybees to thepresenceof 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 evenwhen 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 thefollowing 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 toadult 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’stemperature.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 inspring.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–combtemperature 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 asignificant 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, suggestingthatincreased temperature is not optimal when broods are not infected, as well asthat 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 feverdoes 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 raisedthe 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。
