加快转变经济发展方式，促进国民经济又好又快发展，关键在于实现______。
A．由主要依靠投资、出口拉动向依靠消费、投资、出口协调拉动转变
B．由主要依靠第二产业带动向依靠第一、第二、第三产业协同带动转变
C．由主要依靠增加物质资源消耗向主要依靠科技进步、劳动者素质提高、管理创新转变
D．由主要依靠政府投资拉动向主要依靠政府投资与民间资本协同拉动转变
参考答案：A,B,C
解析： 本题测查军转干考生科学发展观(转变经济发展方式)理论素养。加快转变经济发展方式，促进国民经济又好又快发展，关键在于实现三个转变，即由主要依靠投资、出口拉动向依靠消费、投资、出口协调拉动转变；由主要依靠第二产业带动向依靠第一、第二、第三产业协同带动转变：由主要依靠增加物质资源消耗向主要依靠科技进步、劳动者素质提高、管理创新转变。
British and American scientists are raising genetically modified(转基因的) pigs in the hope of providing organs for transplant(移植) to humans, the project leader wrote in a newspaper Sunday. Scientists in London and California have begun conducting the genetic experiments to find a solution to record–long waiting lists for organ transplants, Robert Winston said in an opinion piece written for Britain'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 organs might save the lives of humans." The scientists are introducing human genes into the animals to reduce the chances of the organs being rejected by patients, as has been common in previous attempts to use animal tissues, said Winston, who heads the Institute of Reproductive and Developmental Biology at London's Hammersmith Hospital. Working with Dr. Carol Redhead of the California Institute of Technology, Winston's team has injected human genes directly into male piglets(猪仔), adding them to the animal'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 U.S. friends will benefit from our technology and the income we might have produced for Britain will be lost," Winston wrote. Some scientists have previously blamed the idea of using animal organs for human transplant, saying the technique risks spreading animal viruses to humans. Winston said his research project is attempting to breed virus-free pigs. 49. Scientists are introducing human genes into the animals to ____________.
