Walk through the Amazon rainforest today and you will find that it is steamy,warm,damp(潮湿的) and thick.But if you had been there around 15,000 years ago,during the last ice age,would it have been the same?For more than 30 years,scientists have been arguing about how rainforests like the Amazon might have reacted to the cold,dry climates of the ice ages,but until now,no one has reached a satisfying answer.
Rainforests like the Amazon are important for mopping up CO2 from the atmosphere and helping to slow global warming.Currently the trees in the Amazon take in around 500 million tons of CO2 each year:equal to the total amount of CO2 giving off in the UK each year.But how will the Amazon react to future climate change?If it gets drier,will it still survive and continue to draw down CO2?
Scientists hope that they will be able to learn in advance how the rainforest will manage in the future by understanding how rainforests reacted to climate change in the past.Unfortunately,getting into the Amazon rainforest and collecting information are very difficult.To study the past climate,scientists need to look at fossilized pollen,kept in lake mud.Going back to the last ice age means drilling deep down into lake sediments (沉淀物) which requires specialized equipment and heavy machinery.There are very few roads and paths,or places to land helicopters and aeroplanes.Rivers tend to be the easiest way to enter the forest,but this still leaves vast areas between the rivers completely unsampled (未取样).So far,only a handful of cores have been drilled that go back to the last ice age and none of them provide enough information to prove how the Amazon rainforest reacts to climate change.

1.What does the underlined phrase “mopping up” in the second paragraph mean?
A.Giving off. B.Taking in.
C.Wiping out. D.Giving out.
答案:B
解析:词义猜测题。根据下文的“helping to slow global warming”可知是指“吸收二氧化碳”,take in意思是“吸收”。故选B项。
2.What is the main difficulty in studying the Amazon rainforest?
A.How to set foot deep on it.
B.How to go back to the ice age.
C.How to collect equipment.
D.What to use to do research.
答案:A
解析:细节理解题。根据最后一段的“There are very few roads and paths,or places to land helicopters and aeroplanes.Rivers tend to be the easiest way to enter the forest,but this still leaves vast areas between the rivers completely unsampled (未取样).”可知答案。
3.How do the scientists study the past of rainforests?
A.By predicting the future of the rainforests.
B.By studying the past climate and its future.
C.By learning the history of the rainforest.
D.By doing research on the lake sediments.
答案:D

4.What is the best title for this passage?
A.Studies on the Rainforests
B.Climates of the Amazon
C.Secrets of the Ice Ages
D.Changes of the Rainforests
答案:A
解析:主旨大意题。根据第一段的“no one has reached a satisfying answer”和第三段的“Scientists hope that they will be able to learn in advance how the rainforest will manage in...To study the past climate,scientists need to look at fossilized pollen,kept in lake mud.”可知,本篇文章是介绍科学家们对热带雨林的研究。
