【答案与解析】本文主要介绍了热带雨林对气候的影响。
1. B。词义猜测题。根据第二段中的 helping to slow global warming，同时结合化学知识可推知 mopping up 的意思是吸入。另外，文章中的currently the trees in Amazon take in around 500 million tones of CO2 each year 也暗示 mop up 和 take in 的意思相同。
2. D。事实细节题。根据文章第2段的内容(尤其是最后一句话)可推知此题最佳答案为D。
3. C。主旨大意题。根据文章最后一段中的So far, only a handful of cores have been drilled 可知，资料收集不是很容易。
4. C。主旨大意题。文章主要讲的是亚马孙热带雨林难以预料的变化，所以选C为佳。
B
Terrible weather, melting(融化的) snow and gathering clouds may be signs of global warming. The average temperature on Earth for last year was the second warmest since written records began 140 years ago.
The global average surface temperature in 2001 was 14.42 degrees centigrade, the World Meteorological Organization said. The record, set in 1998, was 14.58 degrees centigrade.
Temperatures are getting hotter, and they are getting hotter faster now than at any time in the past, said Michel Jarraud, a WMO official.
Carbon dioxide(二氧化碳) produced from burning fuels is the most common of the so-called greenhouse gases. The growing concentration(集中) in the atmosphere of these gases is thought to be warming the Earth. Most of the causes of global warming are due to human action, said Ken Davidson, director of WMOs climate programme department.
Every year, large amounts of gases produced by factories, cars and burning trees hold in too much heat and cause global warming. Many scientists believe the warming, if not stopped, will cause extreme climate changes this century.
Throughout the world, the spreading of particular diseases and other threats(威胁) to human health depend largely on local climates. Extreme temperatures can directly cause loss of life. Warm temperatures can increase air and water pollution, which in turn can harm human health.(责任编辑：www.360gaokao.com)
