Answer 1

分析 短文介绍了 Peter Kalmus从自身出发，做自己力所能及的事情来节能减排．

解答 61．a　考查冠词．句意为我是两个孩子的父亲，故此处使用a．
62．burning考查分词． avoid是动词，避免的意思，后接动名词做宾语．
63．which　考查定语从句，此处是 一个非限制性定语从句，缺少主语． 
64．to respond　考查动词不定式．have no choice but to do表示别无选择做某事．
65．deeply　考查副词．此处修饰短语combined with 表示深深地有着关系．
66．have written/have been writing 考查时态．根据句子里recently可知，时态为现在完成时，即have written；另外根据句意推测，我一直在写一本书，可能还没写完，还会继续写，故使用现在完成进行时，即have been writing．
67．ecological 考查形容词． 此处修饰dilemma需用形容词形式，即生态的窘境．
68．in考查介词．in our society为固定短语，意思是在我们的社会里．　
69．and考查连接词．根据前句our structures of thinking and belief可知，此处and连接并列成分，及 belief和the ways．
70．ourselves考查代词．此处the biosphere，each other以及ourselves都是作为relate to的宾语，句意为我们与整个生物圈包括我们自己都有关系．
