VOA——Voice Of America，作为世界上最大的新闻广播机构之一，服务于美国政府,但不一定代表美国政府的观点.多年来，它的英语节目如“一部活的教科书”，帮助全球各地的英语学习者掌握现代英语的发展动向，培养准确连贯的英语语感，学习地道的英语语言。下面我们将把VOA的英文广播的精彩时空展现在你面前，领你进入“原汁原味”美语世界。英国广播公司（British Broadcast Company），简称BBC，成立于1922年，是英国最大的新闻广播机构，也是世界最大的新闻广播机构之一。BBC虽然是接受英国政府财政资助的公营媒体，但其管理却是由一个独立于政府以外的12人监管委员会负责，并且通过皇家宪章保障其独立性。监管委员以公众利益的信托人的身份管理BBC，他们都是社会上有名望的人士，包括苏格兰、威尔斯、北爱尔兰和英格兰的首长，由英国首相提名，英女皇委任。CNN是美国有线电视新闻网——Cable News Network的英文缩写，由特纳广播公司（TBS）董事长特德·特纳于1980年6月创办，通过卫星向有线电视网和卫星电视用户提供全天候的新闻节目，总部设在美国佐治亚州的亚特兰大。

This is the VOA Special English Development Report. Nanotechnology uses matter at the level of molecules and atoms. Researchers are finding different uses for particles with a length of one nanometer, or one-billionth of a meter. These include things like beauty products and dirt-resistant clothing. But one area where many experts believe nanotechnology holds great promise is medicine. Last week, speakers at a program in Washington discussed using nanotechnology to improve health care in developing countries. The program took place at the Woodrow Wilson International Center for Scholars. Peter Singer at the University of Toronto says a nanotechnology called quantum dots could be used to confirm cases of malaria. He says it could offer a better way than the traditional process of looking at a person's blood under a microscope. In poor countries, this process is often not followed. As a result, sick people may get treated for malaria even if they do not have it. Such misuse of medicines can lead to drug resistance. Quantum dots are particles that give off light when activated. Researchers are studying ways to program them to identify diseases by lighting up in the presence of a targeted molecule. Experts say nanotechnology shows promise not just for diagnosing diseases, but also for treating them. Piotr Grodzinski of the National Institutes of Health talked about how nanotechnology could make drugs more effective. He talked about cancer drugs already developed with nanotechnology. He says if a drug can target a cancer locally in the body, then much less of it might be needed, and that means lower side effects. Andrew Maynard is chief scientist for the Project on Emerging Nanotechnologies at the Woodrow Wilson Center. He noted that Brazil, India, China and South Africa are currently doing nanotechnology research that could help poor countries. But he also noted that there is some risk in using nano-materials. He says nanometer-sized particles behave differently in the body and the environment compared to larger particles. Experts say more investment in research is needed to better understand these risks. And that's the VOA Special English Development Report, written by Jill Moss. Transcripts and audio files of our reports are at voaspecialenglish.com. I’m Steve Ember. w 里有很多。
