笔者在查阅《汉语成语考释词典》(商务印书馆1991版)时,发现有“同路人”的条目,很感兴趣;但细读内容之后,又产生了怀疑。该条目引孟郊《伤时》诗“有财有势即相识,无财无势同路人”作书证。诗句中“同路人”的“同”是个独立的词,意思是“好像”“如同”,跟前一句子里的“即”相对;“路人”指不相干的人。而作为一路同行或者暂时追随革命的“同路人”里的“同”是个词素,有“一齐”“一同”(从事)的意思。 When I read the “Dictionary of Chinese Idioms” (Commercial Press, 1991 edition), I found “fellow travelers” entries, very interested; but after reading the content, but also had a suspicion. The entry cited in the Mengjiao “injury time” poem “a wealth of potential that is acquainted with no money with the potential of people” as a card. The “sameness” of “fellow travelers” in the verse is an independent word, which means “as if” “likeness”, as opposed to “immediateness” in the previous sentence. “Passerby” refers to unrelated people. And “same” in “fellow travelers” who are fellow travelers or who temporarily follow the revolution is a morpheme and has “together” and “together.”
