Answer 1

分析 兩中國殘疾公民自愿在中國北方種植的樹木，他們的事跡鼓舞人心．他們立志保護環(huán)境，八荒地變成了綠洲．

解答 61．voluntarily   考查副詞．此處是用副詞來修飾動詞plant"自愿種樹"．
 62．has been organized  考查時態(tài)．根據時間狀語since2011 可以判斷出主句用現在完成時，又因為
 63．to find 考查非謂語．本句用動詞不定式做定語修飾the first 句意：這次活動是第一次在基層人民中找到英雄．  
64．whom   考查定語從句．先行詞是 Jia Wenqi and Jia Haixia，定語從句中both of后只能用whom．
65．as/though 考查連詞．本句是讓步狀語從句，as/though引導的讓步狀語從句，句子可到裝．句意：雖然他們殘疾，但他們在過去的13年里在井陘縣種了10000多棵樹．
66．improving 考查固定短語．prevent…from doing 是固定短語"阻止某人做某事"，improve與動詞flooding是并列的，所以答案填improving．   
 67．devoted 考查非謂語．they與devote之間是被動關系 they are devoted，所以用過去分詞在句中做狀語．           
68．a  考查固定短語．a number of 是英語的固定搭配"許多大量"．      
69．difference   考查名詞．根據句子判斷此處要填名詞，difference是名詞"不同"．
70．for 考查介詞．句意：他們應該被稱為生態(tài)英雄，因為他們非凡的努力和驚人的行為．介詞for表原因．

點評 語法填空是通過語篇在語境中考查語法知識的運用能力，在解題前應快速瀏覽短文掌握大意，在讀懂短文的基礎上，結合短文提供的特定的語言環(huán)境去逐句分析．要解決好語法填空，離不開堅實的語法知識，有了堅實的語法知識才能對語言進行正確的分析和判斷，從而答對題目．
