Have you ever heard of e-waste ( electric 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 electric industry,e-waste pollution has become a serious problem. According to the United Nations,in 2014,people around the world produced 41. 8 million tons of e-waste and only recycled 6. 5 million tons. The US was the biggest waster,producing 7. 1 million tons. China came second,with 6 million tons.

It's important to pay attention to e-waste. It can either be valuabe or harmful (有害的) ,depending on how we deal with it. E-waste is a valuable urban mine (城市礦藏). 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 people throw them away,the toxic chemicals (有毒化學(xué)物質(zhì)) can get into the earth or air,effecting the environment and people's health.

Apple,for example,now recycle people's used products in China when 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) ewaste,we can also take computers and phones to see if companies offer recycling programs.

If you need glasses to read this,you are a-mong most of Chinese students. About four-fifths of high school students in China have poor eyesight (視力) . And now more and more children in primary school need glasses,too.

Two main reasons can cause poor eyesight: too much time spent indoors studying and too little time spent outdoors playing. Reading and writing for hours and hours,sometimes in poorly lighted rooms,causes eyesight to weaken. But students have to do this because there is so much pressure on them to succeed in school. They have less time to enjoy the sun.

The sun,it turns out,is important in developing good eyesight. According to a study by Australian National University,Australian children and Chinese children have the same level of eyesight before they start school,but once they enter primary school,Chinese children only spend about an hour a day outside,while Australian children spend three to four hours each day in the sunshine. The result is that while about forty percent of Chinese primary school students need glasses,only three percent of Australian children do.

And poor eyesight at a young age can have serious long term influence. As you get older,your eyesight can worsen.

With all that in mind,don't you think it's time to give your eyes a break?

() 1. How many high school students have poor eyesight in Ghina according to the reading?

   A. A half of them.

   B. Three percent of them.

   C. Forty percent of them.

   D. Four-fifths of them.

() 2. Which can cause poor eyesight accord ing to the reading?

   A. Like reading and writing very much.

   B. Spend too much time enjoying the sun.

   C. Spend too much time indoors studying.

   D. Start primary school at a young age.

() 3. What can we learn from the third para graph?

   A. Primary school studying can be very harmful to young students.

   B. Australian children spend more time outdoors than Chinese children.

   C. After primary school,children in China and Australia have the same eyesight.

   D. Fewer Chinese primary school students have poor eyesight than Australian

() 4. What does the writer want to tell us?

   A. Remember to give our eyes a break.

   B. Develop good eyesight in Australia.

   C. Avoid poor eyesight at an old age.

   D. Spend little time outdoors playing.
