  Ear Breakthrough

  (1) New research published in the journal Current Biology has added significantly to understing of how the ear wks, giving hope to millions of deaf hard of heating people.

  (2) The latest research, conducted by Dr. Jg T. Albet, a Deafness Research UK research fellow at the UCL Ear Institute, together with scientists at the University of Cologne, shows that fruit flies have ears which mechanically amplify sound signals in a remarkably similar way to the sensy (感觉的) cells found in the inner ear of vertebrates (脊椎动物) including humans.

  The finding means that the wealth of genetic techniques already available to study the fruit fly can now be used to target how the ear wks.

  (3) Dr. Albert says. "The biophysical parallels between the ways both fruit flies humans convert sound into nerve signals are truly amazing. We may be allowed to hope that these mechanistic (机械学的) similarities extend further down to the genes molecules that bring about heating. But even if it finally should turn out that heating in fruit flies relies on different molecules than does heating in humans, the little fruit fly can help us find answers to some key questions of hearing research - what is sometimes even me imptant- will surely help us ask the right questions. "

  (4) The wk is welcomed by Deafness Research UK, the country's only medical research ity f deaf people. Vivienne Michael, chief utive of Deafness Research UK, says, "This is an imptant advance that paves the way toward a clear understing of the genetics of deafness.

  (5) The ity will continue to suppt culling-edge (尖端的) research through its Fellowship programme at the UCI. Ear institute at other top research centres in the UK to achieve our goal of securing audical improvements in the prevention, diagnosis treatment of all fms of heating impairment"

  (6) There are nine million deaf hard of hearing people in the UK in most cases deafness results from loss of sensy cells in the inner ear known as "hair" cells. The cells can be damaged lost through ageing, noise, genetic defects certain drugs ,because the cells don't regenerate, the result is progressive - irreversible -hearing loss.

  Damage to these cells can also lead to tinnitus (耳鸣), which affects around five million people in the UK.

  31. Aperson who is hard of hearing is__________.

  A. not able to hear properly

  B. totally deaf fm birth

  C. unwilling to listen to others

  D. ignant of how the ear wks

  32. Quite a number of genetic techniques have been used__________.

  A. to target how the ear wks

  B. to study the fruit fly

  C. to stimulate sensy cells

  D. to amplify sound signals

  33. Fruit files humans share similarities in how they__________.

  A. ask answer questions

  B. pass on their genes

  C. reproduce

  D. convert sound into nerve signals

  34. Vivienne Michael from Deafness Research UK highly appreciates__________.

  A. the genetics of deafness

  B. the ity's Fellowship programme

  C. improvements in treating hearing impairment

  D. the latest research conducted by Dr.Albert.

  35. Heating loss caused by damage to the sensy cells__________.

  A. can affect five million people in the UK

  B. can be progressively repaired

  C. cannot be cured

  D. cannot lead to tinnitus

  答案与解析

  31.A。细节题。题干:有听力障碍的人__________。利用题干关键词hard ofhearing可以定位到第一段,从中可知新的研究促进了对耳朵如何工作的理解,给上百万的聋人以及有听力障碍的人带来了希望,由此可以推知那些有听力障碍的人与耳聋的人一样都有听力问题,所以该题答案为A(不能准确听到)。

  32.B。细节题。题干:很多基因技术已经被用来__________。利用题干关键词genetic techniques可定位到文章第二段的最后一句,即研究结果意味着大量的用于研究果蝇的基因技术可以用来研究人的耳朵是如何工作的,由此可知这些基因技术已经被用来研究果蝇了,所以该题答案为B(来研究果蝇)。

  33.D。细节题。题干:果蝇和人类在如何 __________ 方面存在相似性。利用关键词fruit files,humans和similarity可以定位到第三段的第一句,可知Dr.Albet认为果蝇和人类将声音转化为神经信号的方式存在生理物理学方面的相似性,这确实是令人诧异的,四个选项中只有选项D与原文信息相关,所以该题答案为D(把声音转化为神经信号)。

  34.D。细节题。题干:来自耳聋研究中心的Vivienne Michael赞成。利用题干关键词Vivienne Michael可以定位到第四段的第二句,可知Vivienne Michael认为这是项重要的进步,为清晰地了解耳聋的遗传学做了很好的铺垫,而这项进步指的就是指Dr.Albert开展的最新研究的最新发现,所以该题答案为D(Dr.Albert开展的最新研究)。

  35.c。细节题。题干:因为感知细胞受损引起的听力丧失__________。利用题干关键词damage to the sensy cells可以定位到文章最后一段,可知这些感知细胞因为衰老、基因缺陷以及某些药品而受到破坏甚至失去,因为这些细胞不能繁殖,结果就导致逐渐的但是不可逆的听力的丧失,同时也会导致耳鸣,所以该题答案为C(无法治愈)。
