[简答题]克隆羊“多莉”的诞生与死亡给人类以怎样的启迪和思考?
[单项选择]I had an experience some years ago which taught me something about the ways in which people make a bad situation worse by blaming themselves. One January, I had to officiate at two funerals on successive days for two elderly women in my community. Both had died "full of years", as the Bible would say both yielded to the normal wearing out of the body after a long and full life. Their homes happened to be near each other, so I paid condolence (吊唁) calls on the two families on the same afternoon.
At the first home, the son of the deceased (已故的) woman said to me, "If only I had sent my mother to Florida and gotten her out of this cold snow, she would be alive today. It’s my fault that she died. " At the second home, the son of the other deceased woman said, "If only I hadn’t insisted on my mother’s going to Florida, she would be alive today. That long airplane ride, the abrupt change of climate, was more than she could take. It’s my fault that she’s dead. "

About the time that
schools and others quite reasonably became interested in seeing to it that all
children, whatever their background, were fairly treated, intelligence testing
became unpopular.
Some thought it was unfair to minority
children. Through the past few decades such testing has gone out of fashion and
many communities have indeed forbidden it.
However,
paradoxically, just recently a group of black parents filed a lawsuit (诉讼) in
California claiming that the state’s ban on IQ testing discriminates against
their children by denying them the opportunity to take the test. (They believed,
correctly, that IQ tests are a valid method of evaluating children for special
education classes. ) The judge, therefore, reversed, at least partially, his
original decision.
And so the argument goes on and on. Does it
benefit or harm children from minority groups to have their intelligence tested
We ha
A. draw public attention to IQ testing
B. put an end to special education
C. remove the state’s ban on intelligence tests
D. have their children enter white schools
