问题 Some 121 countries may be designated "developing", and of this 121, seventeen countries ______more than four-fifths of energy consumption.

选项 A、amount to
B、account for
C、add up
D、take away

答案B

解析 词组辨析。amount to“总计,等于”;account for除了表示“说明”以外,还可以表示“占……比例”;add up“合计,加起来达到的预期总数”;take away“取走,拿走”。根据句中ofthis 121,seventeen countries可以判定是,17个国家在121个国家所占的比例,只有account for符合句子的含义。故答案为B。
