正确答案为选项C，其在录音中的对应内容是Dangote is known as a softly spoken workaholic， with all the trappings of wealth，其中的 trappings 意为外部标志 (outward signs, outward decoration or dress) , 与题干中的 sign of wealth —致。选项 A 错在把财富值与Dangote最接近的富翁的$7.9 billion身价说成了二者之间财富 的差额。选项B 前半部说Dangote说话温柔虽然与录音内容相符，但后半部分说他工作不拼命，这一点与录音所说的他是个工作狂（workaholic)意思相反。选项D 说他发财是通过在尼日利亚赌博，而录音说的是他在尼日利亚国内经济发展方面投 机而发财，两者意思不一样。

[重点难点]
理解 trappings of wealth与 sign of his wealth的关联意义，灵活理解 gambling on在特殊语境下的含义。
