问题 We must be committed______the deep greenhouse gas reductions since we need to avoid the worst outcomes of climate change.
选项 A、on
B、with
C、in
D、to
答案 D
解析    (1)句子结构。
   主句为主谓结构，主语为we，must be committed to…为谓语，since引导的是原因状语从句。
   (2)选项词义。
   本题的考查的是commit的搭配。commit的搭配为commit sb．／oneself(to sth．／to doing sth．)(常用被动态)，有“承诺，保证，致力于”等意义。
   本句大意为“我们不想面对气候变化带来的最糟结果，所以必须大幅度减少温室气体排放”。从搭配来看，只有选项D正确。
