选项 A、settling
B、inhabiting
C、existing
D、establishing
答案 B
解析 此题为词语辨析题。文义并不难理解，是“居住在我们这个星球上的人”的意思。A) settling 是“to establish one’s residence (定居，建立某人的住处)”的意思，既可以作及物动词，又可以作不及物动词使用，其用法是“settled her family in Ohio (她家定居俄亥俄)；settled in Canada (定居加拿大)”，可见与居住在星球上，在语义上有些差别。B) inhabiting 的含义是“居住于，存在于，占据，栖息”，可以作及物和不及物动词使用，所以为正确答案。C) existing 是“存在”的意思，与文意相距甚远。D) establishing 是“建立”的意思，与上下文的意思不符。
