高中英语完型填空试题练习
Corless and his team are engaged in a project that falls somewhere between toxic-waste cleanup and money making. They’ve invented a process that 【1.】 them, in effect, to 【2.】 carbon dioxide out of the air. Every day at the plant, roughly a ton of CO2 that had 【3. 】floated 【4.】 is turned into calcium carbonate. The substance is then heated, and the gas is forced off, to be 【5.】 containers. The calcium can then be 【6.】 , and the process run through all over again.
“If we’re successful at building a business around carbon【 7.】 , these are trillion-dollar markets,” Corless said.
This past April, the concentration of carbon dioxide in the atmosphere reached a record four hundred and ten parts per million. The amount of CO2 in the air now is probably
【8.】 than it’s been at any time since the mid-Pliocene, three and a half million years ago, 【9. 】there was a lot less ice at the poles and sea levels were sixty feet higher. This year’s record will be surpassed (超越)next year, and next year’s the 【10. 】after that.
【11. 】every country fulfills the commitment made in the Paris climate accord—and the United States has said that it doesn’t intend to—carbon dioxide could soon reach levels that, it’s widely agreed, will 【12. 】catastrophe, 【13.】 it hasn’t already done so.
Carbon-dioxide removal is, potentially, a trillion-dollar enterprise because it offers a way not just 【14. 】the rise in CO2 【15.】 to completely change it. The process is sometimes 【16.】 as “negative emissions”: 【17.】 adding carbon to the air, it removes it. Carbon-removal plants could be built anywhere, or everywhere. Construct enough of them 【18.】 , in theory at least, CO2 emissions could continue without any 【19.】 and still we could avoid catastrophe. Depending on how you 【20.】 things, the technology represents either the final security measure against global warming or the final moral risk.
