Gene therapy and gene based drugs are two ways we could benefit from Our growing mastery of genetic science.
But there will be others as is one of the remarkable therapies on the cutting edge of genetic research that could make their way into mainstream medicine in the coming years.
While it’S true that just about every cell in the body has the instructions to make a complete human，most of those instructions are inactivated，and with good reason：the last thing you want for your brain cells is to start churning out stomach acid or your nose to turn into a only time cells truly have the potential to turn into any an all body parts is very early in a so-called stem cells haven’t begun to specialize.
Yet this untapped potential could be a terrific boon to diseases involve the death of healthy cells-brain cells in Alzheimer’s，cardiac cells in heart disease，pancreatic cells in diabetes，to name a few;if doctors could isolate stem cells，then direct their growth，they might be able to furnish patients with healthy replacement tissue.
It was incredibly difficult，but last fall scientists at the University of Wisconsin managed to isolate stem cells and get them to grow into neural，gut，muscle and bone process still can’t be controlled，and may have unforeseen limitations;but if efforts to understand and master stem cell development prove successful，doctors will have a therapeutic tool of incredible power.
The sanle applies to cloning，which is really just the other side of the cloning，as first shown with the sheep Dolly two years ago，involves taking a developed cel and reactivating the genome within，resetting its developmental instructions to a pristine that happens，the rejuvenated cell can develop into a full—fiedged animal，genetically identical to its parent.
For which purely physical characteristics like milk production in a cow or low fat in a hog have real market value，biological carbon copies could become routine within a few past year scientists have done for mice and cows what Ian Wilmut did for Dolly，and other creatures are bound to join the cloned menagerie in the coming year.
Human cloning，on the other hand，may be technically feasible but legally and emotionally more difficult.
Still，one day it will ability to reset body cells to a pristine，undeveloped state could give doctors exact：
ly the same advantages they would get from stem cells：the potential to make healthy body tissues of all sorts，and.
thus to cure could prove to be a true“miracle cure”.
writer holds that the potential to make healthy body tissues will_____.
[A]aggravate moral issues of human cloning
[B]bring great benefits to human beings
[C]help scientists decode body instructions
[D]involve employing surgical instruments
word“rejuvenated”(Para.5)most probably means_____.
[A]modified
[B]recoliccted
[C]classified
[D]reactivated
research at the University of Wisconsin is mentioned to show_____.
[A]the isolation of stem cells
[B]the effects of gene therapies
[C]the advantages of human cloning
[D]the limitations of tissue replacepmnts
h of the following is true according to the text?
[A]The principle of gene therapy is applicable to that of cloning.
[B]The isolation of stem ceils is too difficult to be feasible.
[C]It is reasonable for all body instructions to be activated.
[D]Cloned animals will eventually take control of the world.
rds the genetic research，the author’s attitude can best be said to be that of_____.
[A] frustration
[B]indifference
[C]amazement
[D]opposition

短文賞析
基因治療和以基因為基礎的藥物是我們從遺傳科學中獲得利益的兩種方式。在未來幾年內，這些基因療法會發展成為主流醫學。如果醫生利用基因知識，分離幹細胞，然後培育這些細胞，他們就可能為病人提供健康的移植組織。這種技術同樣也有助於克隆技術的發展，以後越來越多的動植物將會被克隆，甚至人本身。排除道德法律的因素，利用基因克隆培養出來的人的各種健康器官，一些病將會被更好的治療。
答案及解析
51.B【解析】文章開宗明義，在第一段講述到，如果我們掌握了基因科學，將會對人類有極大的好處。此外第三段的第一句“Yet this un?tapped potential could be a terrific boon to medicine”，意為“然而這種沒被開發的潛能對醫學有極大的好處”，作者在全文的`最後一句又呼應了這一觀點。故應選B。
52.D【解析】此詞出處在第五段，“rejuvenated”和前一句的“reactivating”構成一種近義的重複。故應選D。
53.A【解析】由第四段“…the University of Wisconsin managed to isolate stem cells…”可知，雖然研究很困難，但這所大學還是在去年秋天設法分裂了幹細胞。故應選A。
54.A【解析】文章後面指出其實基因治療的原理和克隆的原理兩者完全是可以通用的，具體的解題點在於文章的第五段第一句話“the same applies to cloning”。故應選A。
55.C【解析】這是一個關於作者態度的綜合分析題。作者儘管提到有
困難，但科學家們正在談論克服困難的辦法而且非常努力，並且作者最後說道“That could prove to be a true‘miracle cure”’，當真正使用克隆技術為人類治療的時候，那將會是真正的“神奇醫療”。故應選C。
