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.

這是考研考試真題里的一句話，最后的how lecturing people was not the best way to change their behavior. 應該是賓語從句，但引導詞how在從句中干什么成分，怎么樣翻譯？

《韋氏詞典》將這種how剖析為連詞，覺得等于that引導從句。但《牛津》則覺得還是方法副詞。不過當從句謂語為靜態動詞表示狀況時，方法的意味非常弱，假如從句作動詞賓語，則可以用that替換，句義不變。但that從句不能作介詞賓語。所以當how引導名詞性從句作介詞賓語，而從句謂語為靜態動詞表示轉態時，可以將how視為連詞不作成分，如此更容易理解分句結構。
