Ⅱ.阅读理解

A

Cloning is suggested as a means of bringing back a relative, usually a child, killed unfortunately. Some parents can understand that wish, but it must first be recognized that the copy would be a new baby and not the lost child. Here lies the_difficulty,_for the sad parents are seeking not a new baby but a return of the dead one. Since the original would be fondly remembered as having particular talents and interests, would not the parents expect the copy to be the same? It is possible, however, that the copy would develop quite differently. Is it fair to the new child to be placed in a family with such unnatural expectations?

Copying is also suggested as a means by which parents can have the child of their dreams. Couples might choose to have a copy of a film star, baseball player or scientist, depending on their interests. But because personality is only partly the result of genetic inheritance, conflicts would be sure to arise if the cloned child failed to develop the same interests as the original. What if the copy of Einstein shows no interest in science? Or the baseball player turns to acting? Success_also_depends_on_fortune. What if the child does not live up to the hopes and dreams of their parents simply because of bad luck?

Every child should be wanted for itself, as a person. In making a copy of oneself or some famous person, a parent is purposely specifying the way he or she wishes that child to develop. In recent years, particularly in the U. S., much importance has been placed on the right of individuals to reproduce in ways that they wish. So I suggest there should be

a greater need to consider the interests of the child and to reject these suggested uses of cloning.

11. The underlined part “the difficulty”in Paragraph 1 refers to ________.

A. cloning a baby is difficult

B. it's difficult to give birth to a new baby

C. the dead child can't come back again
