问题补充：
The Group of Eight (G8) the eight richest countries in the world.
A. is made up
B. consists of
C. is consisted of
D. consist of
答案：
A. is made up
(答案→)B. consists of
C. is consisted of
D. consist of
解析：考查固定词组，is made up意思“被组成”，consists of意思“由……组成”，没被动式，主动表示被动，因为The Group of Eight是主语，是单数，所以后面的动词用单数，因为consist以辅音字母t结尾，所以加s句子意思“在某种程度上我同意你”，所以选B
