问题     Dr. Richard Stevens, a Senior Lecturer in Psychology at the Open University, gives his opinion on cloning:
    "Cloning is a very curious issue that people get so uptight about. In a sense, the whole process of reproduction is a kind of cloning—it’s just that you’re mixing the genes of two people, and with cloning you’re not doing that—you’re just having the genes from one person. So it doesn’t seem to me particularly striking in a way. People’s fears seem to me rather unjustified and I think a lot of the fears around cloning stem from the inappropriate or mistaken notion that somehow one is cloning the person you are as an adult, which is of course not the case at all. All you’re doing is passing on your genetic make-up, and all those features which make you into a human being—a complex function of interactions between your genetic potential and environmental influence, through the course of your lifetime—are not going to be part of that cloning process. You’re only going to have the basic genetic make-up, which is hardly that different from giving to a child a shuffling of genes from two parents.
    So, from a psychological standpoint, cloning doesn’t seem to me to raise that dramatic issue. It might possibly raise issues from a biological standpoint because of course sexual reproduction has all sorts of advantages and has had advantages in evolutionary terms. It avoids inbreeding of various kinds. I think sexual reproduction gives a lot more diversity—at least the genotypical mixtures that are around among individuals. So there may be problems on that score, but I don’t really see it’s a fundamentally radical step. Cloning to me is not a big deal, it’s not a big issue. It was quite an exciting thing when it was done from a technical point of view, but from a moral point of view and a practical point of view I don’t think it’s that relevant."
Dr. Richard Stevens explains that cloning will not duplicate an adult individual because he believes that ________.
选项 A、cloning does not go through most processes which make one into a human being
B、a cloned person lacks genes from two parents
C、cloning is less complex than sexual reproduction
D、environment has no influence on a cloned person
答案A
解析 细节题。理查德．史蒂文斯博士认为克隆人不会是某个成年人的副本，原因是他认为造就一个人的大多数过程是克隆不了的。All you’re doing is passing on your genetic make—up，and all those features which make you into a human being—a complex function of interactions between your genetic potential and environmental influence，through the course of your lifetime——are not going to be part of that cloning process．克隆复制的只是人的基因组合，而人的其他特征，理查德．史蒂文斯博士解释说，是克隆不了的，是人一生中遗传因素与环境影响相互作用的复杂结果。
