TEXT ONE
When honey bees began to desert their hives recently, never to return, it threw apiarists into a panic. What appeared to be perfectly healthy adult bees would flee their queen, the young and their foodstores. Instead of ransacking the empty hive, other bees would avoid it like the plague. Yet there was nothing obviously wrong. Researchers have now identified the first tangible clue in the mystery?a relatively new virus. Colony collapse disorder became widespread in America in the winter of 2006-07, when about a quarter of the nation's beekeepers were affected, each losing between 30% and 90% of their winged workers. Bees are valued not so much for their honey, which is worth some $200m a year in America, but for their work in pollinating crops. This brings the economy some $15 billion a year, as apiarists move their hives to land producing fruit, vegetables and nuts. Finding exactly why colonies collapse has been taxing the minds of both federal and university scientists. There have been few bodies on which to conduct autopsies. Those adult bees that have been found dead near an abandoned hive have been riddled with almost every bee disease known to man. Now a report by Diana Cox-Foster of Pennsylvania State University and her colleagues, published in the September 6th issue of Science, points the finger at the Israeli acute paralysis virus. The lurgy in question was, the researchers suggest, imported from Australia. Because many factors could be acting together to cause bee colonies to collapse, Dr Cox-Foster and her colleagues decided to examine everything they could find within the empty hives. They collected samples from infected hives and compared them not only with samples from apparently healthy hives but also with an analysis of royal jelly?a bee secretion fed to the larvae?from China, which has not been affected by the mystery disorder. From their samples, the researchers extracted RNA?a chemical that carries and helps to decode genetic information. Their analysis revealed the presence of various bacteria, fungi and viruses that were lurking in the hives and the royal jelly. They then looked to see whether there was anything in the abandoned hives that was not found elsewhere. What they found was a virus first identified in 2004 in the Middle East. Bees infected with Israeli acute paralysis virus shiver, their bodies become frozen and they die. But the virus itself cannot be the sole cause of colony collapse disorder. For a start, all the hives infected with it were also infested with a second nasty, the Kashmiri bee virus. Yet this virus was also present in many of the apparently healthy hives. Intriguingly, there was also a virus that the researchers were unable to classify. They suspect it may be a new lineage of the Kashmiri bee virus, but it could be something completely novel. This second virus was also found only in the abandoned hives.
The researchers reckon that the reason why so many honey bees are dying is down to a combination of factors that are found only, so far, in America. The Israeli acute paralysis virus may have had such a devastating effect there because of the presence of a parasite called the varroa mite. This parasite weakens the immune systems of bees, making the consequences of an infection more likely to be fatal. Tellingly, bees in Australia have not been infected by the parasite.

  1. When honey bees desert their hives, the other bees will usually [A] stay far away from the empty hives because they are useless. [B] flee their queen, the young and their food stores away and steal the hives. [C] throw apiarists into a panic by plaguing the empty hives. [D] plunder the empty hives and take possession of all that is worth anything.
  2.When the bee colony collapse disorder became rampant in America, [A] the workers of the nation’s beekeepers resigned from the beekeeping factory. [B] the apiarists moved their hives to land producing fruit, vegetables and nuts. [C] the crops could not grow to maturity as before short of effective pollination. [D] and each apiarist suffered a loss of $200m to $1b a year as well as most of their workers.
  3.It has been a headache to find out why bee colonies collapse because of the following reasons except [A] RNA experiment shows an intricate connection between the dead bees with their Chinese counterparts. [B] dead bees near a deserted hive are found to carry too many diseases. [C] there were almost no samples for scientists to do research on the dead bees. [D] the scientists could not identify exactly which disease was the main factor that causes the colonies collapse.
  4.Which one of the following statements is NOT TURE of the experiment carried out by Dr Cox-Foster and her colleagues?
[A] They collected samples not only from infected hives, but also from healthy hives and royal jelly. [B] They sorted out a chemical that provides relevant information from the genetic perspective [C] The research points out that an Israeli virus is the main cause of the collapse disorder since the virus was found in the hives and the royal jelly [D] They found that there were all kinds of viruses in the royal jelly which were also present in the infected hives.
  5.According to the researchers, so many honey bees are dying probably because of the following reasons except [A] the bees were affected with Israeli acute paralysis virus which was fatal to them. [B] the hives were infected with a combination of the viruses that lead to massive deaths of the bees. [C] an unidentified virus which may be a new lineage of the Kashmiri bee virus or a new virus causes the disaster. [D] the varroa mite is believed to worsen the conditions of the infected bees and leave them more vulnerable to deadly disease. 篇章剖析: 篇章剖析: 这篇文章讲述了目前美国发生的蜜蜂离开蜂房的灾害性情况。第一段讲述这种 情况可能和某种病毒有关;第二段讲述过去蜂房倒塌的情况;第三、四、五段 和第六段讲述针对该情况的一项研究。 词汇注释: 词汇注释: apiarist n. 养蜂家 pollinate v. 对…授粉 lurgy n. 疾病 难句突破: 难句突破: (

题目分析: 题目分析:
  1. When honey bees desert their hives, the other bees will usually [A] stay far away from the empty hives because they are useless. [B] flee their queen, the young and their food stores and steal the hives. [C] throw apiarists into a panic by plaguing the empty hives. [D] plunder the empty hives and take possession of all that is worth anything. [答案] D [难度系数] ☆☆

  1. 蜜蜂抛弃了自己的蜂巢时,其他的 蜜蜂一般会 [A] 远 离 空 巢 , 因 为 这 些 空 巢 没 有 用。 [B] 离开它们的蚁后、幼蚁和食物储 藏地并偷窃他们的蜂巢。 [C] 给空巢带来瘟疫,将养蜂家置于 恐慌。 [D] 掠夺空巢并占有其中有价值的任 何东西。
[分析] 细节题。根据第一段“Instead of ransacking the empty hive, other bees would avoid it like the plague”,可见其他的蜜蜂没有去掠夺空的蜂房,反而像躲 避瘟疫一样,说明了在一般情况下,它们都是要洗劫空巢的。显然只有选项 D 为正确答案。
2 . When the bee colony collapse disorder became rampant in America, [A] the workers of the nation’s beekeepers resigned from the beekeeping factory. [B] the apiarists moved their hives to land producing fruit, vegetables and nuts. [C] the crops could not grow to maturity as before short of effective pollination. [D] each apiarist suffered a loss of $200m to $1b year as well as most of their workers. [答案]C [难度系数] ☆

  2. 蜜蜂王国崩溃在美国变各处普遍发 生的时候, [A] 养 蜂 人 的 工 人 都 从 养 蜂 场 辞 职 了。 [B] 养 蜂 人 将 自 己 的 蜂 房 移 到 产 水 果、蔬菜和坚果的地方。 [C] 由于缺乏有效的受精,作物不能 像以前那么长成熟了。 [D] 养蜂人每年要损失两亿至十亿美 元、并失去大部分的工人。
[分析] 根据第二段的分析“Bees are valued not so much for their honey, which is worth some $200m a year in America, but for their work in pollinating crops. This brings the economy some $15 billion a year, as apiarists move their hives to land producing fruit, vegetables and nuts”,可见蜜蜂的真正价值在于可以给谷物授 粉,如果蜜蜂王国崩溃,那么谷物不能授粉,也就不能正常生长成熟了,因此 只有选项 C 符合题意。
  3.It has been a headache to find out why bee colonies collapse because of the following reasons except [A] RNA experiment shows an intricate connection between the dead bees and their Chinese counterparts. [B] dead bees near a deserted hive are found to carry too many diseases. [C] there were almost no samples for scientists to do research on the dead bees. [D] the scientists could not identify exactly which disease was the main factor that causes the colonies collapse. [答案] A [难度系数] ☆☆☆ [分析] 根据第三段,蜜蜂王国崩溃,一方面是由于没有蜜蜂可供研究,而那些 死蜂身上疾病太多,无法辨别是哪个引起的。因此,B、C、D 都是原因,其中 B 选项的对应信息是“Those adult bees that have been found dead near an abandoned
  3.要找出为什么蜜蜂王国崩溃的原 因是个头疼的事情,因为除外 的其他原因。 [A] 核糖核酸试验显示了在死亡的蜜 蜂和他们在中国的远亲之前有一种复 杂的联系 [B] 在空巢附近的死蜜蜂带有太多的 疾病 [C] 几乎没有样品可以供科学家研究 死亡的蜜蜂 [D] 科学家不能精确地辨别出到底是 哪个因素导致了蜜蜂王国的崩溃
hive have been riddled with almost every bee disease known to man”,B 选项对应的 信息是“There have been few bodies on which to conduct autopsies”,D 选项对应于 “Finding exactly why colonies collapse has been taxing the minds of both federal and university scientists”。A 选项的对应信息在第五段,从中我们可以发现比较的是 “中国蜂王浆”,而且也没有提到什么“intricate connection”,因此该选项表述与 文章不符,是正确答案。
  4.Which one of the following statements is NOT TURE of the experiment carried out by Dr Cox-Foster and her colleagues? [A] They collected samples not only from infected hives, but also from healthy hives and royal jelly.
  4.关于 Cox-Foster 博士和其同事进行 的试验,下列哪个陈述是错误的?
[A] 他 们 不 仅 从 染 病 的 蜂 巢 搜 集 样 品 , 也 从健 康 的 蜂巢 和 蜂 王浆 中 搜 集。 [B] They sorted out a chemical that [B] 他们挑选了一种能从基因角度提 provides relevant information from the 供有用信息的化学物质。 genetic perspective [C] The research points out that an Israeli [C] 研究指出一种以色列病毒是蜂房 virus is the major cause of the collapse 崩溃的主因,因为他们在蜂房和蜂王 disorder since the virus was found in the 浆中都发现了这种病毒。 hives and the royal jelly [D] They found that there were all kinds of [D] 他们在蜂王浆中发现的各种病毒 viruses in the royal jelly which were also 在染病的蜂巢中也存在。 present in the infected hives. [答案] C [难度系数] ☆☆☆☆ [分析] 细节题。根据第四段和第五段,首先根据 A 选项显然是正确的,“They collected samples from infected hives and compared them not only with samples from apparently healthy hives but also with an analysis of royal jelly”。B 选项有一定的难 度,其实这种“a chemical that provides relevant information from the genetic perspective”就是在第四段中提到的 RNA,即核糖核酸。D 选项是正确的,对应 信息在文章第四段的“Their analysis revealed the presence of various bacteria, fungi and viruses that were lurking in the hives and the roya
