四、（镇江京口区期末改编）阅读材料，完成下列任务。
Many things in our life are helpful. Mobile phones help us talk with friends. Televisions make our life fun. But when they get old, they will become e-waste(电子垃圾).
What is e-waste?
It refers to all discarded things with batteries or wires .
What effects(影响) does e-waste have on the Earth?
Much e-waste is bad for the Earth. For example, one mobile phone battery can pollute（污染）60 cubic metres（立方米）of water.
How can we deal with(处理) e-waste?
• Recycling You can give it to a recycling centre or recycle it by yourself. An artist made some works with old phones. After making them, there was only a little e-waste left. The works were cool. “I think we should try our best to protect the environment. One of the great ways is to make full use of e-waste,” the artist said.
• You can take it to a second-hand market. Some people like to use older and cheaper products. And you can get money from these old things.

（二）1. A 解析 由材料中“For example, one mobile phone battery can pollute 60 cubic metres of water.”可知，一块手机电池能污染60立方米的水源，则三块手机电池会污染$(60×3=)180$立方米的水源。故选A。
2. B
3. C 解析 由空处后的“You can take it to a second-hand market.”可推测，本段落的核心内容为将电子垃圾带到二手市场进行售卖，则空处的段落标题应该填 Selling(出售；售卖)。故选C。
