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 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, 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 study, 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 .
【文章说了一种病原体,简称A病原体.蜜蜂幼虫吃了含有A的食物之后,体内会长一种致命的菌简称CB.但是CB要在低于幼虫正常体温的情况下才会发作,所以CB主要是在春天侵害小规模的蜜蜂群. 最近一个研究发现.在蜂群感染了A之后,那些负责维持蜂房温度的蜜蜂会有意识地提高蜂房温度. 而这个发烧现象,或者说温度的提升是在没有一个幼虫死亡之前发生的.可能说明蜜蜂的这一反应是一个保护性措施.而且要么是那些蜜蜂在感染症状出现之前就发现了它们,要么就是幼虫把感染信息告诉了蜜蜂. 实验结束的时候,又恢复正常了,说明升高的温度并不是蜂群的最佳温度,也说明这个发烧现象不仅仅是蜂群数量增大的结果.】
24. The primary purpose of the passage is to
discuss the findings and implications of a particular study
illustrate a process that formerly had been misunderstood
outline the methods used to investigate a problem
provide evidence to support a controversial theory
contrast alternative interpretations of certain date
25. According to the passage, researchers concluded that fever in honeybee colonies ispreventative because their study showed that such fever
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.
protests adult bees from contracting chalk brood infection 防止成年蜜蜂接触感染.
occurs prior to the death of any larvae 在任何幼虫死亡之前发生.
is more likely to occur in spring than in summer 相较于在夏天,更可能在春天发生.
does not have an effect on uninfected broods 对于没有感染的蜜蜂没有影响..
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
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)
up-regulation of temperature is a preventative measure against chalk brood 说明升温是保护性措施.
honeybees are incapable of purposely raising hive temperatures 蜜蜂不能有意识地升高蜂房温度. .
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.
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.
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.
27. According to the passage, which of the following is true of chalk brood infection among honeybee larvae?
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.
Infection with chalk brood induces larvae to raise their hives temperature. 感染使得幼虫升高蜂房的温度.
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.
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.
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. .
