Answer 1

分析 两中国残疾公民自愿在中国北方种植的树木，他们的事迹鼓舞人心．他们立志保护环境，八荒地变成了绿洲．

解答 61．voluntarily   考查副词．此处是用副词来修饰动词plant"自愿种树"．
 62．has been organized  考查时态．根据时间状语since2011 可以判断出主句用现在完成时，又因为
 63．to find 考查非谓语．本句用动词不定式做定语修饰the first 句意：这次活动是第一次在基层人民中找到英雄．  
64．whom   考查定语从句．先行词是 Jia Wenqi and Jia Haixia，定语从句中both of后只能用whom．
65．as/though 考查连词．本句是让步状语从句，as/though引导的让步状语从句，句子可到装．句意：虽然他们残疾，但他们在过去的13年里在井陉县种了10000多棵树．
66．improving 考查固定短语．prevent…from doing 是固定短语"阻止某人做某事"，improve与动词flooding是并列的，所以答案填improving．   
 67．devoted 考查非谓语．they与devote之间是被动关系 they are devoted，所以用过去分词在句中做状语．           
68．a  考查固定短语．a number of 是英语的固定搭配"许多大量"．      
69．difference   考查名词．根据句子判断此处要填名词，difference是名词"不同"．
70．for 考查介词．句意：他们应该被称为生态英雄，因为他们非凡的努力和惊人的行为．介词for表原因．
