When a Scottish research
team startled the world by revealing 3 months ago that it had cloned an adult
sheep, President Clinton moved swiftly. Declaring that he was opposed to using
this unusual animal husbandry technique to clone humans, he ordered that federal
funds not be used for such an experiment, although no one had proposed to do so,
and asked an independent panel of experts chaired by Princeton President Harold
Shapiro to report back to the White House in 90 days with recommendations for a

a meeting on 17 May, members agreed on a near-final draft of their
recommendations.

[单项选择]Some people hate everything that is modern. They cannot imagine how anyone can really like modern music; they find it hard to accept the new fashions in clothing; they think that all modern painting is ugly; and they seldom have a good word for the new buildings that are being built everywhere in the world. Such people look for perfection in everything, and they take their standards of perfection from the past. They are usually impatient with anyone who is brave enough to experiment with new or to express himself or the age in materials original ways. It is, of course, true that many artists do not succeed in their work and instead produce works that can only be considered as failures. If the work of art is a painting, the artist’s failure concerns himself alone, but if it is a building, his failure concerns others too, because it may damage the beauty of the whole place. This does sometimes happen, but it is completely untrue to say, as some people do, that modern architecture is noth
