问题 Taking a cell, practically any cell, from your body, the theory goes, and through appropriate  biological tinkering(摆弄) you can cause it to grow into a duplicate of yourself—identical from eyelashes to toenails. No need for procreational(生育的) sex any more;(51) this system, you can neatly reproduce yourself without a(52). Human cloning, it is called. Science fact or science fiction? What would happen if human cloning became a(53)? One favorite scenario is the(54)of a new(55)of Hitlers—or Einsteins. Scientists quickly disclaim the possibility. "It is more than genetic make-up that makes an individual." Says Markert of Yale University, "We are all products of a particular(56)era and of a special environment, with so many minute things(57)the way we develop each and every day, even in the womb, that a duplicate background--and therefore a duplicate(58)could never be created."
   Already biologists studying the cell’s(59)workings and the various methods of cloning have made discoveries that may ultimately lead to breakthroughs(60)the fight against cancer, control of the aging process, and the conquest of more than 100 presently incurable human genetic diseases. To(61)cloning-related research would mean closing the  door(62)and important area of knowledge. To continue to probe the secrets of the cell, however, is perhaps to(63)the secret of human cloning. And, given the nature of man, if it can be done it will be done. What then is the(64)?
   Says Congressman Rogers: "It is clear that human cloning is not yet possible. The day when it will be—if ever—is far(65). For now, at least, the benefits of cell-biology research outweigh the risks."
选项 A、private
B、inner
C、personal
D、individual
答案B
解析 本句意为：“研究细胞内部活动和无性生殖各种方法的生物学家们已经做出了多种发现，他们可能最终导致在对付癌症、控制老化过程以及征眼一百多种目前尚无法抑制的遗传病症方面实现突破。”选项中只有inner符合题意。
