First: C, Second: B, Third: A 5. 1-a, 2-c, 3-b 解析： 1.C 【解析】文章明确指出，森林的叶子（通过树木）吸收有害气体，从而清洁空气。选项C与此描述一致。其他选项描述的是森林的其他功能或与原文不符。 2.B 【解析】文中提到，树根像一块大海绵一样，能够保持土壤和水分。选项B直接对应了文本中描述树根作用的这句话。 3.C 【解析】文章建议的帮助森林的方式包括植树、节约用纸、以及有时步行或骑自行车。而“总是为短途出行使用汽车”会增加污染，与保护森林的建议相悖，因此是“不正确”的做法。 4.First: C, Second: B, Third: A 【解析】排序题。根据文章逻辑，首先介绍森林是动物的家园（C），然后提到树木清洁空气（B），接着说明树根保持水土的功能（A）。这个顺序符合文章从生物到环境功能的叙述层次 5.1-a, 2-c, 3-b 【解析】匹配题。需要将森林的“超能力”与其具体益处对应起来。“为动物提供家园”对应“提供庇护的能力”（a），“清洁空气”对应“净化的能力”（c），“保持气候凉爽并涵养水分”对应“气候调节的能力”（b）。 短文翻译 森林如何保护我们的绿色地球 森林就像我们地球的绿色超级英雄。它们是许多动物的家，比如小鸟、小兔子和熊。树木和植物为动物们提供食物和安全的住所。如果没有森林，这些动物就会无家可归。 森林为我们做了许多重要的工作。它们的叶子通过吸收有害气体，来净化我们呼吸的空气。它们的根抓住土壤和水分，就像一块大海绵，这样我们就有干净的水可以喝。它们还能帮助保持天气凉爽宜人。 我们可以帮助我们的森林朋友！我们应该多种树，节约用纸，不伤害植物和动物。多走路或骑自行车，而不是总开车，这也是很好的做法。让我们一起过绿色生活，保护我们美丽的绿色地球吧！ $
