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."
Different from sexual reproduction, cloning ______.
选项 A、has advantages in terms of evolution
B、means one is reproducing the person you are as an adult
C、gives to a child a mixture of genes from two parents in a random way
D、means passing on one’s basic genetic make-up to a baby
答案D
解析 细节题。题目是：不同于有性生殖，克隆——。四个选项内容分别是：A．有利于进化；B．意味着克隆人是某个成年人的复制品；C．给了孩子双亲的随机混合基因；D．意味着把基本遗传组合传给罂儿。根据第二段后半部分及第三段内容，A实际上是有性生殖具备的优点，B是理查德·史蒂文斯博士批驳的一种错误观念，C也是有性生殖的特点(第二段)。而选项D在第二段则有明确表述，是题目的正确选项。
