He has also criticized the celebrity chef Jamie Olivers high-profile attempt to improve school lunches in England as an example of how lecturing people was not the best way to change their behavior.
这是考研考试真题里的一句话，最后的how lecturing people was not the best way to change their behavior. 应该是宾语从句，但引导词how在从句中干什么成分，怎么样翻译？
《韦氏词典》将这种how剖析为连词，觉得等于that引导从句。但《牛津》则觉得还是方法副词。不过当从句谓语为静态动词表示状况时，方法的意味非常弱，假如从句作动词宾语，则可以用that替换，句义不变。但that从句不能作介词宾语。所以当how引导名词性从句作介词宾语，而从句谓语为静态动词表示转态时，可以将how视为连词不作成分，如此更容易理解分句结构。
