Answer 1

分析 After listening to the professor's inspiring lecture，more （university） graduates were willing to devote themselves to the cause of environmental protection．

解答 After listening to the professor's inspiring lecture，more （university） graduates were willing to devote themselves to the cause of environmental protection．
根据句意"听完这个教授鼓舞人心的讲座，有更多的大学毕业生愿意"可知，这是描述的过去的事实，所以用一般过去时．
本句可以使用时间状语从句的省略结构，be willing to do sth乐意做某事；devote oneself to （doing）sth致力于（做）某事．

点评 while，when，as，after等引导的时间状语从句，当从句中的主语和主句的一致，且从句中含有be动词时，可以省略从中的主语和be动词．还有一点需要注意短语中devote oneself to 中的to为一介词，后面跟动词时需要用动词的ing形式．
