选C In my opinion,(all he does )主语 （ does ）助动词用来强调谓语 （ do ）谓语
good to his students in his class at present .He is very strict in their study.
句子前半段意思是 依我看 目前他所做的确实对他的学生有帮助... 第二个 does 是用来强调谓语 do 的 英语里强调谓语的话要借助 助动词完成 有了助动词 动词就保持原形
例如 He helped us at last. 这句话如果要强调谓语 helped 的话，
就应该是 He did help us at last.
I
