如果statements是TRUE, 划A; 如果statements是FALSE, 划B。) Cloning is a radical challenge to the most fundamental laws of biology; so many people are concerned that it might be a preface to activities that will threaten human society and dignity.

Conservative spiritual leaders have claimed that cloning a human constitutes a gross attack on human dignity. That would surely be true if a cloned individual were treated as a lesser being, with fewer rights or lower status. But why suppose that the laws that protect our rights and dignity would not be applicable to cloned person?

Many of the vivid warnings of science fiction concerning the prospect of human cloning turn out, upon reflection, to be wildly improbable. There’s the fear, for instance, that parents might clone a child for the sake of having “surplus parts” in case the original child needs an organ transplant. But parents of identical twins don’t view one child as an organ farm for the other. Why should cloned children’s parents be any different?

Another disturbing thought is that cloning will lead to efforts to breed individuals with genetic qualities perceived as desirable. Such ideas are offensive, not only because of an unthinking disgust, but also because of the horrors carried out by the Nazis in the name of improving their race. But there’s a vast difference between the breeding programs as practiced by some groups (where the urge to breed certain types of people leads to efforts to destroy other types) and the much more harmless forms already practiced in democratic societies (where, say, lawyers freely choose to have sexual relations with other lawyers). Banks stocked with the frozen sperm of ge niuses already exist, but they haven’t created a master race because few women are queuing up to get pregnant this way. Why should we think it would be different if human cloning becomes available?

Even if human cloning offers no obvious benefits to mankind, why ban it? If it might go any further, it should---and no doubt will---take place only under careful examination and layers of legal administration. Most important, human cloning should be governed by the
