0301This is the VOA Special English Development Report.We talked last week about counterfeit medicines and how the problem is especially bad in Africa, Asia and Latin America. The World Health Organization says up to thirty percent of the medicine sold in many developing countries is not real.It also estimates that up to fifty percent of the medicine sold on the Internet is counterfeit. That can put people at risk even in wealthy countries that represent only a small part of the counterfeit drug market.Today we look at what is being done to fight counterfeit drugs.Several companies are developing ways to make counterfeits easier to identify. And there are existing methods, like a machine that can quickly identify chemicals in pills to confirm if the pills are real.Other ideas include things like special tracking codes for drug packages. People could send a text message with the code and get a message back confirming that what they bought is listed in a database.Some drug makers and other companies put three-dimensional images called holograms on their products as a security device.Other anti-counterfeit efforts include the use of radio frequency identification tags. Many companies use these electronic tags to follow products through the supply chain from the manufacturer. The American Food and Drug Administration says R.F.I.D. tags act like an electronic safety net to make it easier to catch counterfeits.Last July, the Food and Drug Administration advised manufacturers to add what are called physical chemical identifiers to their medicines. These are special chemicals, colorings or tastes that counterfeiters could not easily copy.Bryan Liang is with the Partnership for Safe Medicines, an organization in the United States. He says the Internet is not only a place where people can get tricked into buying counterfeit drugs. It is also a place where counterfeiters can find all the materials they need to make them.BRYAN LIANG: "The Internet is the Wild, Wild West. Anybody can sell drugs. Anybody can buy active ingredients."He says the most important members of the "counterfeit detection team" are the patients themselves. He says raids on counterfeiters are often the result of information from people who bought fake medicines.BRYAN LIANG: "The best approach is to know your drug. Know what they feel like. Know what they taste like. Know what your traditional reactions are. A person that knows their drugs and the effects of their drugs are in fact the best security against fakes."And that's the VOA Special English Development Report, written by June Simms.

常速VOA跟一般native speaker语速相差不大，大概在150-170词/min，没有经过一定的语境训练听起来肯定有难度。慢速也就相当于我国中学英语的水平吧，如果慢速完全无压力了，可以慢慢往常速转。重点要过词汇关，很多时候听力水平决定于你听到某个词的反应时间，我们听VOA之所以困难，往往就是因为一个生词还没反应过来，又听到了好几个生词，非常狼狈。所谓台上一分钟，台下十年功，若要人前显贵，必得人后受罪，没有别的捷径，多听、坚持听、反复听，并且要逐词逐句听写出来跟原文对照，每听完一篇之后再把里面的生词总结出来，结合语境、有声有色地去记忆。这样假以时日，肯定会有效果。听懂VOA常速基本可以达到专业八级的听力水平，然后还可以听语速更快的BBC、CNN和NPR等。记住练听力不仅是单纯的听，而是一个词汇量、句型、语法、写作各种能力综合提升的过程。
