6．using　动词use和主语he之间构成逻辑上的主谓关系，故此处用现在分词短语作伴随状语。

　　7．mainly　副词修饰动词、形容词、副词或整个句子，在句子中作状语。故用副词mainly修饰谓语动词。

　　8．by/through　根据语境可知，此处表示"以......方式/方法"，与上文中的"only means of transport"呼应，故用介词by/through。

　　9．the　along the way为固定搭配，意为"在......过程中"，符合语境，故用定冠词。

　　10．that/which　此处用that/which引导定语从句，在从句中作主语，修饰先行词the environmental message。
