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. But let’s think, what is the practical value in doing so? You may tell me that it can bring hope for those couples【C17】______to have children because they might choose to have a copy of one of them rather than【C18】______the gene intrusion from a【C19】______But imagine, if you have a child owning the same appearance as yours or your husband’s, will you accept it without any【C20】______.
【C4】
选项 A、probably
B、eventually
C、likely
D、possibly
答案D
解析 副词辨义题。possibly表示“某件事在行为者(尤其是作为人的行为者)力所能及的范围内”，也可以表示“某件事的可能性”，这时说明的是事物的性能。probably在表示某人做某事，或事物的可能性时，具有“迹象”或推理的内涵。likely所修饰的人或物应当具备这样的特点：已被断定，被提出或被坚持的可能性。结合文意分析，这里是对未来情况的预料，并不是由某种原因进行推导得出结论，而且也不是已经断定的结果，因此possibly是最恰当的选项，故选D。eventually意为“终于”，表示事情顺利成章的发生了，实际上已经默认了结果，没有猜测、可能的含义在内，不符合文意，可排除。
