Wilmut maintains that cloning animals has tremendous potential for helping people. Cloned Sheep, he says, could be used as living drug factories. Scientists could "engineer" sheep that produce drugs in their milk. And by altering the proteins on the surfaces of animal organs to make them more like human organs, scientists believe they may be able to create a plentiful source of organ donors for people.
Why not clone humans as organ donors? Theoretically, Wilmut says, there is no reason his techniques couldn’t someday be used to clone people. Think about the possibilities: a whole basketball team of Michael Jordans, a scientific panel of Albert Einsteins, a movie starring and co-starring Brad Pitts.
On a more serious note, some experts argue that couples who have difficulty having a baby could make copies of themselves. And parents whose child has a fatal disease like cancer might be able to clone the child, creating a twin who could be a bone-marrow (骨髓) donor.
But even Ian Wilmut draws the line at cloning humans. "All of us would find that offensive," he says. Several countries, including Britain, Denmark, Germany and Australia, have made all scientific work on cloning humans illegal. The U.S. has no such law, but President Clinton has set up a panel of scientists and philosophers to study the issue. In the meantime, Clinton has imposed a ban on using federal money to clone humans.
Humans are more than the sum of their genes, argues a philosopher at one research institute. Though they look exactly the same, clones are not necessarily exact copies. The younger twin might grow up with different influences—say, unusual friends or special teachers. A cloned Albert Einstein might fail his physics class. A cloned pop star might sing terribly.
Say you were cloned. Would your twin live a shorter life because he or she started out with DNA that was already 10, 20 or 30 years old? Scientists aren’t sure. And how could you prevent someone from taking a sample of your hair and making a clone of you? Again, no solutions.
What do you think? Should scientists be allowed to clone animals? How about humans?
Wilmut, a world-famous researcher on cloning, believes that ______ .
选项
A、cloning animals has already assisted human beings a lot in two aspects
B、his techniques may be applicable to people in order to create geniuses
C、line should be drawn and cloning animals is offensive
D、cloned sheep engineered to produce drugs in milk can be used as living drug factories
答案
D
解析
第一段第一句话明确指出:Wilmut maintains that cloning animals has tremendous potential for helping people. Cloned sheep, he says, could be used as living drug factories.意为:Wilmut认为克隆动物有巨大的有助于人类的潜力。他说,“克隆羊,可用于生物制药厂”。故选D。
