题目解答
答案
本题考察宾语从句的语序及疑问词选择。根据题意，“Who is he?”需转换为间接引语“You may ask Mary who he is.”。
- A和C为疑问语序，不符合要求。
- C和D中“whom”不能作主语，排除。
- 只有B“who he is”符合陈述语序，且“who”可指代“he”。
答案：B. who he is
解析
本题考查宾语从句的语序及疑问词选择。关键点在于：
- 宾语从句需使用陈述语序，即疑问词后接主语和谓语；
- 疑问词的选择：需根据从句中主语和谓语的逻辑关系确定疑问词的格（主格/宾格）。
原句是直接引语“Who is he?”，转换为间接引语时：
- 调整语序：直接引语是疑问句，间接引语需改为陈述语序，即“who he is”；
- 确定疑问词：从句中“he”是主语，需用主格代词“who”，排除使用宾格“whom”的选项C、D；
- 排除错误选项：选项A保持原疑问语序，不符合宾语从句规则；选项C、D的“whom”无法作主语。
