1、小綜合訓練17對應學生用書p154.閱讀理解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?guī)r) 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 (菱鎂礦) 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.”【語篇解讀】本文是一篇科普說明文。加拿大的科學家想通過實驗室生產出一種菱鎂礦，用它來吸收地球上的溫室氣體二氧化碳，雖然在室溫下

7、就可進行這個試驗，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.解析細節(jié)理解題。根據(jù)第一段第一句話可知，科學家在實驗室制造菱鎂礦的目的就是想用它來吸收二氧化碳，從而減緩

8、氣候變化的速度。故選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.解析細節(jié)理解題。根據(jù)第三段中“a ton of this mineral can store about half a ton of carbon dioxide.”可知，一噸菱鎂礦可以儲存半噸的二氧化碳。故選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.解析細節(jié)理解題。根據(jù)第四段最后一句可知，在實驗室制造菱鎂礦需要耗費大量昂貴的能源。故選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.解析推理判斷題。根據(jù)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，用這種人工合成的礦物吸收二氧化碳還需要很多改進。故選a。答案a.完形填空lehrner always wanted to design roller coas
