Have youheard of e-waste (电子垃圾), which can be produced every day? How do you deal with yourcomputers, MP4 players or mobile phones when they're broken or you want a newone?

    Mostpeople just throw them away. With the development of electronic industry (电子产业), e-waste pollution has becomea serious problem. According to the United Nations, in 2014, people around theworld produced 41.8 million tons (吨) of e—waste and only recycled 6.5 million tons. The US was the biggestwaster, producing 7.1 million tons. China came second, with 6 million tons.

    It'simportant to pay attention to e-waste. It can be either valuable or harmful,depending on how we deal with it. E-waste is a valuable urban mine (城市矿藏). The value of the metals,like gold and silver in the waste around the world, is surprising. And themetals can be reused. But if people throw them away, the toxic chemicals (有毒化学物质) can get into the earth or air,affecting the environmentand people's health.

    Apple, forexample, now recycles people's used products in China when they are buying newones. The company will test and repair the used ones and sell them at lowerprices. To help reduce e-waste, we can buy longer-lasting electronic products.If you have unwanted electronics, find a new home for them. You can also takecomputers and phones to companies to see if they offer recycling programs.

Lu Xun is one of the greatest Chinese writers of the 20th century. Besides his famous stories, he also wrote many influential(有影响力的) articles about the life of Chinese people. 

Born in a {#blank#}1{#/blank#} (wealth) family in 1881, Lu Xun had a happy childhood. {#blank#}2{#/blank#} (unlucky), his father became seriously ill and died in 1896. From that tine on, his family were no longer accepted by their relatives and friends. These early {#blank#}3{#/blank#} (experience) deeply influenced his writing. 

When he studied at university in 1899, he already believed that Chinese society had to change and become modern. In 1902, he went to study in Japan. There, he began writing articles {#blank#}4{#/blank#} several Chinese student magazines to make a living. He showed a gift for writing and translating and he even wrote several books, though none was popular. He returned to China in 1909 because {#blank#}5{#/blank#} (he) family was in need of money. 

After working for several years as {#blank#}6{#/blank#} teacher in Beijing, Lu Xun again returned to writing. In 1918, he created his famous short story Diary of a Mad Man {#blank#}7{#/blank#} was the first Chinese novel to use the everyday language. So it came out to be a great success. And his other novels, such as The True Story of AhQ and Kong Yiji, {#blank#}8{#/blank#} (read) by Chinese young people in that period. 

Although successful, Lu Xun still worried greatly about China' s future. In 1926, he moved to Shanghai and gave up {#blank#}9{#/blank#} (write) stories in order to focus on articles which could call on people to fight for a better country. 

Since his death in 1936, Lu Xun' s influence {#blank#}10{#/blank#} (grow) with time. Today, many of his writings are included in school textbooks and his works are valued by millions around the world.
