56. The following can become e-waste EXCEPT_____.

　　A. computers B. mobile phones C. plastic bags

　　【答案】C

　　【解析】细节题。根据题干except，除了不包括，那么选跟题干不相符合的，而在文章第一段MP4 players and mobile phones when they’re broken or you want a new one?得出C选项与该句中的MP4 playersandmobile phone不属于一类，所以答案为C(塑料袋子)，该题较易。

　　57. Which country produced most e-waste last year according to the United Nations?

　　A. America. B. China. C. Japan.

　　【答案】A

　　【解析】细节题。根据题干定位到第二段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.即可得出答案的同意替换US即America，所以答案为A，该题中等。

　　58. What does the underline word “affecting” mean in this passage?

　　A. 保护 B. 影响 C. 改善

　　【答案】B

　　【解析】猜词题。根据关键词定位到the toxic chemicals(有毒化学物质) can get into the earth or air, effecting the environment and people’s health，那么计入有毒物质进入到了土壤和空气中，那么根据因果关系，所以对环境和人们的健康肯定是有影响的。所以答案为B，该题较易。
