问题     The news of the first successful cloning of a sheep has sent shock waves around the world. As a result, in many countries, officials and even some scientists are calling for new or strengthened legislation to outlaw human cloning, although at this early date, no concrete measures have been proposed. In the United States, which currently has no law prohibiting the procedure, President Clinton announced an urgent inquiry into the potential ethical and legal implications by the National Bioethics Advisory Commission, which will report its conclusions by the end of May. Meanwhile, Clinton has banned federal funding for human cloning research and asked for a moratorium on nonfederally funded efforts. In addition, both houses of the U. S. Congress had held holding hearings on the issue. Scientists have cloned embryos for the first time from patients with serious diseases and injuries. It is believed that the day will come when some of mankind’s most destructive diseases and injuries can be effectively treated through the use of therapeutic stem cells.
选项
答案 有关克隆羊首次获得成功的消息在世界上引起了轩然大波。结果，在很多国家，政府官员甚至一些科学家都纷纷要求出台新的立法或加强立法，促使克隆人非法化，虽然由于时间关系，尚未来得及提出任何具体的措施。在美国，目前没有一项关于禁止克隆人的法律，克林顿总统下令国家生物伦理学咨询委员会立即对克隆人潜在的伦理和法律含义进行调查，并于5月底前提交结论性报告。与此同时，克林顿已对联邦政府资助克隆人研究下了禁令，并要求暂停非联邦资助。此外，美国参众两院还就此事召开了听证会。目前科学家已首次克隆出严重伤病患者的胚胎。有人认为，将来有一天，可治疗性干细胞将可有效地应用于治疗人类的某些极为严重的疾病和损伤。
