This 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.You can find last week's report on counterfeit drugs at voaspecialenglish.com.I'm Steve Ember.

My school life
I am studying in a middle school named A .It is very big and very beautiful as well as full equipped.
At first when I entered the high school in grade 1,I lived in school.I was not used to it at the beginning.Basically,the students are unfamiliar,I felt so lonely and depressed all day.I could not concentrate on my studies in class,so that for the first time the exam was very poor.
Then my best friend encouraged me that I must be strict with myself and study hard.In a few days we will have the mid-term exam and I want to obtain good results in the examination .
During the lunch and supper time,the school radio station broadcasts popular music and weather report to give us physical and mental pleasure.
I am like the school more and more.

在牛津小学英语3B unit10 Do you play.中
在最后的拓展巩固中 我们可以设计一个survey 调查同学们都玩什么乐器或者球类
可以给学生设计一张表格调查 让学生先利用举行 Do you play.Yes,I do.No ,I don't.What do you play?I play.进行交流 然后再完成表格
任务型教学是学生在完成任务过程中进行对话性互动,进而产生语言习得.
英国语言学家Jane Willis(1996)在她的专著A Framework for Task-based Learning 中提出了任务型课堂教学的三个步骤：1．前任务(Pre-Task)——教师引入任务.2．任务循环流程(Task-cycle)：a.任务(task)——学生执行任务； b.计划(planning)——各组学生准备如何向全班报告任务完成的情况； c.报告(reporting)——学生报告任务完成情况.3．语言聚焦(Language focus)：a.分析(analysis)——学生通过录音分析其他各组执行任务的情况； b.操练(practice)——学生在教师指导下练习语言难点.
