[ D ] the limitations of tissue replacements
4. Which 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 cells is too difficult to be feasible.
[ C ] It is reasonable for all body instructions to be activated.

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
1.B【解析】文章開宗明義,在第~·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 untapped 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。
2.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。
3.A 【解析】由第四段“ 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r幹細胞。故應選A。
4.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。
5.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。
