科目：初中英語 來源： 題型：

 Have you ever heard of e-waste ( electronic waste,電子垃圾) ，which can be produced every day? How do you deal with your computers,MP4 players and mobile phones when they're broken or you want a new one?

Most people just throw them away. With the development of electronic industry,e-waste pollu?tion has become a serious problem. According to the United Nations,in2014,people around the world produced41. 8 million tons of e-waste and only recy?cled6. 5 million tons. The US was the biggest wast?er,producing7. 1 million tons. China came second,with 6 million tons.

It's important to pay attention to e-waste. It can either be valuable or harmful (有害的) ，depen?ding on how we deal with it. E-waste is a valuable urban mine (城巿礦藏) .The value of the metals,like gold and silver in the waste around the world,is amazing. And the metals can be reused. But if peo?ple throw them away,the toxic chemicals (有毒化學(xué)物質(zhì)) can get into the earth or air,affecting the envi?ronment and people's health.

Apple,for example,now recycles people's used products inChinawhen they are buying new ones. The company will test and repair the used ones and sell them at lower prices. To help reduce (減少) e-waste,we can buy longer lasting electronic prod?ucts. If you have unwanted electronics,find a new home for them. You can also take computers and phones to see if companies offer recycling pro?grammes.
