　　较难题目特训：节能环保类

　　阅读下列四篇短文，从每小题后所给的A,B,C或D四个选项中，选出最佳选项。

　　Rainforest is home to around two-thirds of all plant and animal species found on land—in addition to millions of people who depend on them for survival—our remaining ancient forests are some of the most diverse ecosystems known to science. They are also vitally important to the health of our planet, especially when it comes to regulating the climate. But ancient forests around the world are under attack.

　　Protecting rainforests is on the global agenda (议事日程) in a big way. Governments now recognize the importance of protecting tropical forests in order to avoid dangerous climate change, and there is now much debate. As governments try to thrash out the details of a new international agreement, expected to be signed at the end of 2009, they are discussing how best to include measures to save rainforests, and therefore address one of the major causes of climate change. Worldwide, forest destruction causes more greenhouse gas emissions (排放) each year than do all the trains, planes and cars on the planet. So if we are to deal with global warming, there is an urgent need to find ways to reduce the 20% of global greenhouse gas emissions caused by forest destruction each year, and to keep the remaining forests standing.

　　We need to protect the planet’s remaining forests not only to stop climate change from getting worse, but to ensure that we can stand the impacts of global warming. Healthy forests absorb and store quantities of carbon, helping to regulate temperature and generate rain. When they are destroyed, this carbon is released into the atmosphere. Thus keeping forests standing is both a critical part of regulating climate change and of adapting to a warmer world.
