SECTION 3
短文章 (感谢sophice同学的大力支持,呵呵好全的文章^^)
Ingestion of food containing spores of the pathogen Ascosphaera apis caus a fatal fungal dia known as chalk brood in honeybee larvae. However, larvae must be chilled to about 30°C (normal brood-comb temperature is 33-36°C) for the dia 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 purpoly raid 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 respon 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 incread 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 increa in the number of workers available for temperature maintenance).
24. The primary purpo of the passage is to
(A) discuss the findings and implications of a particular study
(B) illustrate a process that formerly had been misunderstood
(C) outline the methods ud to investigate a problem
(D) provide evidence to support a controversial theory
(E) contrast alternative interpretations of certain date
instincts25. According to the passage, rearchers concluded that fever in honeybee colonies is preventative becau their study showed that such fever
(A) does not occur when hive temperatures are within normal range.
(B) protests adult bees from contracting chalk brood infection
(C) occurs prior to the death of any larvae
(D) is more likely to occur in spring than in summer
(E) does not have an effect on uninfected broods
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 rearchers would have been that
(A) up-regulation of temperature is a preventative measure against chalk brood
(B) honeybees are incapable of purpoly raising hive temperatures
(C) A. apis cannot be completely eradicated through up-regulation of temperature along
(D) honeybee larvae have a mechanism to alert adult honeybees to the prence of A. apis
(E) honeybee larvae may benefit from incread hive temperature even when there is no A. apis prent
27. According to the passage, which of the following is true of chalk brood infection among honeybee larvae ？
(A) Larvae in small colonies are more likely to pass the infection to adult honeybees than are larvae in large ones.
(B) Infection with chalk brood induces larvae to rai their hive’s temperature.
(C) The infection is more likely to affect larvae in winter than in spring.
(D) Larvae fail to develop symptoms of the dia when their brood –comb temperature remains within the normal range.
(E) Infected larvae exhibit visible symptoms of dia for a significant time before death.
分析: (均为个人分析,仅供参考)
24. 这题争议不大,基本都选A. findings and implications非常完美地概括了实验的结果和意义.
25. 这题我认为选C,而且多数同学选的也是C. 问的是为什么研究人员认为"发热"是保护行为.
A. 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. 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. 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. 相较于在夏天,更可能在春天发生. than是GRE阅读中非常需要引起注意的词.文中没有明确指出,所以不如C来得更直接,而且有点答非所问.
E. 对于没有感染的蜜蜂没有影响. 同样答非所问吧.
26. 这题牵涉到对文章最后一句的理解,只要取反就可以了.所以我觉得是奴役的意思B,这题争议比较严重wsn是什么意思.其实最后一句的意思就是最终的实验结果p是什么意思(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. 说明升温是保护性措施. 和上述说法取反后不同吧.
B. 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. 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. 幼虫有能力向成年蜜蜂报警. 完全没关系的回答吧.
E. 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. 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. 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. 感染使得幼虫升高蜂房的温度. 这是成年蜜蜂干的活吧.
truemanC. 相比于春天,感染更容易在冬天发生. 虽然冬天看上去温度更低,但是文章说是春天,我们不能以自己先入为主的想法来做题啊.
D. 在蜂群温度正常的时候幼虫身上没有任何感染的病症. 为什么说D对呢,因为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. 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government是什么意思. 这个 a significant time 完全是臆测了.
