【文章內(nèi)容簡(jiǎn)介】 gh school certificate and a light breakfast C. a Tshirt and a gift certificate D. a gift certificate and munity service credit 8. The writer’s purpose in writing the passage is to __________. A. inform readers of some frequently asked questions B. introduce TEENSGIVING in SPRING 2022 to readers C. encourage readers to ask more questions about TEENSGIVING D. call on readers to participate in TEENSGIVING in SPRING 2022 C British and American scientists are raising geically modified(轉(zhuǎn)基因的 ) pigs in the hope of providing ans for transplant(移植 ) to humans, the project leader wrote in a newspaper Sunday. Scientists in London and California have begun conducting the geic experiments to find a solution to record–long waiting lists for an transplants, Robert Winston said in an opinion piece written for Britain39。s Sunday Times. In Britain alone, around 8,000 patients are waiting for a transplant. People needing a new heart or liver are waiting for someone else to die – usually a violent death in a traffic accident, Winston wrote in the newspaper. He said his team was trying to modify pigs so their ans might save the lives of humans. The scientists are introducing human genes into the animals to reduce the chances of the ans being rejected by patients, as has been mon in previous attempts to use animal tissues, said Winston, who heads the Institute of Reproductive and Developmental Biology at London39。s Hammersmith Hospital. Working with Dr. Carol Redhead of the California Institute of Technology, Winston39。s team has injected human genes directly into male piglets(豬仔 ), adding them to the animal39。s sperm(精子 ). He said that pigs involved in experiments had successfully produced transgenic sperm, but acknowledged that British and European laws had prevented the team from using the pigs to mate. The Sunday Times newspaper reported that the experiments would be moved to the United States following difficulties with funding and regulations in Britain. It said the pigs would be bred in Missouri. Our . friends will benefit from our technology and the ine we might have produced for Britain will be lost, Winston wrote. Some scientists have previously blamed the idea of using animal ans for human transplant, saying the technique risks spreading animal viruses to humans. Winston said his research project is attempting to breed virusfree pigs. 第 4 頁(yè) 共 7 頁(yè) 9. Scientists are introducing human genes into the animals to ____________.
