In Disney’s cartoon Wall-E, the robot is left behind on a deserted Earth to clean up the waste mankind left behind. If the latest statistics are anything to go by, we’re in danger of turning that fictional future into a reality.
A decade ago, city residents generated 680 million tonnes of solid waste a year. Now this is 1.3 billion tonnes, and forecast to rise to 2.2 billion tonnes by 2025.
But could technology, which helped create much of this waste, also help deal with it?
Much of the world’s waste goes to landfill sites, which only add to the pollution problem because they produce methane—a greenhouse gas and significant contributor to climate change.
But technology is helping to extract the gas and turn it into electricity. For example, US-based Ener-Core has built installations at landfill sites in California and the Netherlands that can produce between 250 kilowatts and 1 megawatt of electricity.
3. What is the problem mentioned in the news report?
4. What problem does the waste going to landfill sites cause?
选项
A、It is hard to clean up.
B、It can’t be recycled.
C、It can produce a greenhouse gas.
D、It can’t turn into electricity.
答案
C
解析
新闻中提到垃圾放到填埋场会造成环境污染(add to the pollution problem),因为会产生methane“甲烷”,这是一种温室气体(greenhouse gas),会引起气候变化,故C为答案。A“很难清理干净”和B“不能循环再用”都没有在新闻中提到,D“不能发电”与新闻相反,新闻提到有厂家利用这种气体来发电。
