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 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.

　　12．What does the underlined phrase "mopping up" in the second paragraph mean?

　　A．Giving up. B．Giving out.

　　A．It'll get drier and continue to remove CO2 .

　　B．There is no exact answer up to present.

　　C．It'll get warmer and then colder and drier.

　　D．It'll remain steamy, warm, damp and thick.

　　14．What's the main idea of the last paragraph?

　　A．It's important to drill deep down into lake sediments to collect information.

　　B．It's impossible to prove how climate changes in the Amazon rainforest.

　　C．It's hard to collect information for studies of the past climate in the Amazon rainforest.

　　D．It's necessary to have specialized equipment and machinery to study the past climate.

　　15．What is the best title for this passage?

　　A．Studies of the Rainforests

　　B．Climates of the Amazon
