答案： 三、语法填空
[语篇导读]本文是一篇说明文。文章主要介绍了森林的重要性、当前森林面临的来自人类活动的威胁，以及保护森林的相关措施。
1.which 考查定语从句。分析句子成分可知，空处应填引导非限制性定语从句的关系词。先行词是Forests，指物，关系词在定语从句中作主语。故填关系代词which。
2.an 考查冠词。threat是可数名词单数，空处应填冠词。此处泛指“一种日益增长的威胁”，空处应填不定冠词。increasing以元音音素开头。故填不定冠词an。
3.natural 考查形容词。修饰名词homes要用形容词，作定语。故填natural。
4.their 考查代词。修饰名词短语true value要用形容词性物主代词。故填their。
5.previously 考查副词。修饰动词thought要用副词，作状语。故填previously。
6.produced 考查非谓语动词。分析句子成分可知，空处应填非谓语动词作后置定语，修饰carbon dioxide。produce与被修饰短语carbon dioxide之间是被动关系，应用其过去分词形式。故填produced。
7.at 考查介词。at a ... rate of为固定表达，意为“以……的速度”。故填at。
8.to encourage 考查非谓语动词。政府“采取措施”的目的是“鼓励更好的做法”，空处应填动词不定式作目的状语。故填to encourage。
9.organizations 考查名词。分析句子成分可知，空处应填名词作宾语。空处为定语从句that plant trees修饰的先行词，根据从句的谓语plant可知，先行词为复数。故填organizations。
10.contributes 考查时态和主谓一致。在if引导的条件状语从句中，用一般现在时表将来。从句主语everyone为单数，谓语动词用第三人称单数形式。故填contributes。
