【文章大意】众所周知，全球变暖已经成为了一个我们面临的严重的问题，不管是什么导致了全球变暖，我们都应该做一些事情来改变这一现状，或至少减慢变暖的速度。文章中告诉我们，其实很简单，种树就可以。如果地球上有更多的树木，温室气体就会减少，这就将有助于阻止全球变暖。
21.B【解析】上句话“The Wilderness Project has an idea.”提到“荒野计划”这个组织有了一个主意；下句话“If the earth has more trees, greenhouse gases will be reduced, and this will help stop global warming.”就提到了多种树的好处，该空应在中间起到串联的作用，先告诉我们这个主意是什么，B选项“他们建议我们应该多种树”符合语境，故选B。
22.E【解析】上句话“If the earth has more trees, greenhouse gases will be reduced, and this will help stop global warming.”和空后“and improve air quality”都是关于多种树的好处的，E选项“而且，它们通过产生氧气来改善人类健康”也是在说植树的好处，符合语境，故选E。
23.D【解析】根据下文的内容可知，这里列举了比利时、西班牙和德国三个国家的组织和个人采取了不同的措施多种树。D选项“许多国家号召人们种植更多的树木”概括了这一段的文意，符合语境，故选D。
24.F【解析】上句话“In Germany, a teenager named Felix Finkbeiner has been leading a global movement to plant more trees.”提到了德国的一个青少年一直在领导一项种植更多树木的全球运动。F选项“他九岁的时候就有了在世界各地植树的想法”补充了这个青少年更多的信息，符合语境，故选F。
25.A【解析】上句话“So what can you do to help?”提出了问题，“你能做些什么来帮忙呢？”，这个空应给出答案。并且结合空后“although you need to get advice on how to look after it.”“你需要得到一些建议如何照顾它”，因此这个建议是让我们买一棵小树来种植。A选项符合语境，故选A。
