问题     Advanced technology has already pushed human being to edges, such as the production of weapons of mass destruction, the destruction of Ozone by Freon, and the application of clone. The heated debate over【C1】______cloning technique should be used in human reproduction must be considered as a serious【C2】______.
    Clone, to a certain degree, is【C3】______to mankind. Such disease as Parkinsons will【C4】______be cured in the future in the hope of further【C5】______of clone. However, the【C6】______of this technology will bring human being unthinkable destruction.
【C7】______the declaration of the death of Dolly, we are more【C8】______of the inefficient procedure of clone. According to "Dolly’s false legacy", the incidence of death among offspring【C9】______by cloning is much higher than it is【C10】______natural reproduction--roughly 10 times as high as【C11】______before birth and 3 times as high after birth. And【C12】______you may argue that this technology will be perfected in the future, I don’t see there is any point in【C13】______--being cloning.
    Many people【C14】______this technology a promising one as to bring all human being to a new era in which all human【C15】______will be accomplished by cloning.【C16】______scientists in some countries have already started their great plan to clone human.

【C8】
选项 A、conscious
B、known
C、aware
D、worried
答案A
解析 形容词辨义题。conscious强调某种感知到或感觉到的认识，表示“有某件事情的发生而认识到了什么”，符合文意，故A为正确选项。aware指通过自己直觉，如根据别人的态度或者依靠某种信息方式而得到的认识；known仅表示“知道，知晓”，没有“感知”的含义；worried意为“担心，担忧”，不符合文意。
