But they havent come up with an easy way to do it until now, anyway. Researchers in Canada have just proposed a new technology to collect and trap

2、 the greenhouse gas.Limestone (石灰岩) and other minerals already store a lot of carbon dioxide on the earth, notes Ian Power.Hes a geoscientist at Trent University in Peterborough, Canada. The problemthis natural process is slow. It can take thousands or even millions of years. At present, he explains

3、，“Were producing so much carbon dioxide now that the earth cant keep up.”They found that a mineral called magnesite (菱镁矿) locks up carbon dioxide. A ton of this mineral can store about half a ton of carbon dioxide. The chemical normally takes thousands of years to form. But in the lab，Powers group m

4、ade it happen in just a few months.Magnesite occurs naturally. But the process by which it forms on the earths surface is very, very slow. So scientists try to combine rocks and carbon dioxide using lots of heat in the lab. That could make the mineral quicklybut there are a lot of problems to deal w

5、ith to produce magnesite in the lab as well as consuming a lot of costly energy.So far, the scientists have made only a tiny amount of magnesite in the lab. The totalone microgramis about one millionth the weight of a paper clip. “So the process needs a lot of improvement before it can begin trappin

6、g the millions of tons of carbon dioxide produced each year，”says Power. “But a big concern has been overcome，”he says. “Theyve shown it is possible to do this at room temperature and pressure. Now the team can explore how to make the process more efficient.”【语篇解读】本文是一篇科普说明文。加拿大的科学家想通过实验室生产出一种菱镁矿，用它

7、来吸收地球上的温室气体二氧化碳，虽然在室温下就可进行这个试验，但效率仍然很低。1Why do scientists try to make magnesite in labs?ATo show how advanced their technology is.BTo help slow the speed of global warming.CTo create more new materials for mankind.DTo prevent carbon dioxide from being sent into the air.解析细节理解题。根据第一段第一句话可知，科学家在实验室制造菱
