          Don't throw away your old phones.You are actually throwing away real gold!In the smartphones,there are many useful things such as gold,silver and copper(鋼).People can recycle them to make new electronics(電子器件).
              But many people may not know this.In Australia alone there are more than 25 million unused mobile phones lying around.The gold in these phones can add up to a value of more than$80 million(542 million yuan).There are about 2 billion(十億)smartphone users around the world,who change their phones once every 11 months on average.In China,people generate(產生)80 million old phones every year.
              However,it's not easy to get the useful things out of the phones.Smartphones have not only useful things,but also harmful things.Guiyu,a small town in Shantou,Guangdong,is one of the world's biggest dumping grounds (垃圾傾倒場) for electronic waste.Many recycling center sin Guiyu simply break the old electronics and don't think about the pollution it causes.According to a local government report,81 percent of children in Guiyu are harmed by lead(鉛) poisoning.
              Veena Sahajwalle,a professor at Australia's University of New South Wales,has made a mini factory.It makes smartphone recycling cleaner and easier.The mini factory is very small and easy to move around.It breaks the phones and automatically(自動地) takes away the useful parts.That way,humans do not get poisoned.
