Never before ______ so highly successful in changing his surroundings. A. man has been B. man is C. has man been D. is man
题目解答
答案
C
解析
步骤 1：分析句子结构
句子的主语是 "man"，谓语动词是 "has been"，"so highly successful in changing his surroundings" 是表语。句子的结构是 "Never before + 主语 + 谓语 + 表语"。
步骤 2：确定倒装结构
"Never before" 是一个否定副词短语，位于句首时，句子需要部分倒装。因此，主语 "man" 和助动词 "has" 需要倒装。
步骤 3：选择正确的选项
根据倒装结构，选项 C "has man been" 是正确的，因为它符合部分倒装的结构。
