问题 The idea of ______ might worsen the problem of global warming is different to the traditional idea that planting trees can slow down global warming.
What are the two factors that lead to tropical trees cooling down the land?

选项

答案Absorbing carbon dioxide and producing water vapor

解析 由于题干中关键词tropical与文中rain forest zones相呼应,于是定位到原文首段第四句和第五句...in rain forest zones,where more trees absorb more carbon dioxide from the atmosphere.Tropical plants also produce more water vapor,adding to the thick cloud cover that reflects sunlight back into space(那里的树木能够从大气层中吸收更多的二氧化碳,热带雨林还能产生更多的水蒸气,使云层增厚,将太阳光反射回太空)。通过also的提示和句意分析即可得出答案。
