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。
