选项 A、addict
B、entrust
C、commit
D、confide
答案C
解析 固定搭配题。本句与前句之间由or连接，很明显，两句是转折关系。前句的意思是"人类可以选择等待，直到危机迫使我们采取措施"；本句相反，即立即协作，开始行动。空格后出现了to working，可判断to这里是用做介词，而不是不定式标志词，所填词应能与to搭配使用。commit oneself to"致力于"符合题意与用法。addict也可与to搭配使用，addict to意为"耽溺于…，热爱…"，与句意不符；en trust和confide强调对别人信任和相信，用法搭配分别为：entrust sth. to sb.，confide in sb.或confide sth. to sb.例：The task was too important to be entrusted to a child．此任务太重要而不能托付给儿童。She confided her plans to her family．她把自己的计划吐露给家人。
