1、小综合训练17对应学生用书p154.阅读理解scientists have suggested trapping(收集) carbon dioxide in rocks as one way to slow the rate of climate change. 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 the greenhouse gas.li

2、mestone (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，“were producing so mu

3、ch 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 made it happen in just

4、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 with to produce magnesi

5、te 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 trapping the millions of tons

6、 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，用它来吸收地球上的温室气体二氧化碳，虽然在室温下

7、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镁矿的目的就是想用它来吸收二氧化碳，从而减缓

8、气候变化的速度。故选b。答案b2how many kilos of carbon dioxide are locked up in five kilos of magnesite?a2 kilos.b5 kilos.c3 kilos.d2.5 kilos.解析细节理解题。根据第三段中“a ton of this mineral can store about half a ton of carbon dioxide.”可知，一吨菱镁矿可以储存半吨的二氧化碳。故选d。答案d3what do we know about producing magnesite in labs?ait is easy

9、 to do.bits process is complex.cit is energy consuming.dit takes thousands of years.解析细节理解题。根据第四段最后一句可知，在实验室制造菱镁矿需要耗费大量昂贵的能源。故选c。答案c4what can we infer from the last paragraph?ausing minerals to trap carbon dioxide has a long way to go.bmass production of magnesite is on the way.cmagnesite cant be ma

10、de at room temperature.dmost scientists think little of this new method.解析推理判断题。根据最后一段中“so the process needs a lot of improvement before it can begin trapping the millions of tons of carbon dioxide produced each year”可推知，用这种人工合成的矿物吸收二氧化碳还需要很多改进。故选a。答案a.完形填空lehrner always wanted to design roller coas
