单选题 Once he starts talking about Chinese or foreign affairs, ancient or modern, ______.
A. there is no stopping of him B. he is not to stop
C. there is no stopping him D. it is no stopping him

【正确答案】 C

【答案解析】[解析] 此句需要动名词在以there为引导词的句子中作主语，而且往往都是否定句，实际上There is no doing sth. 已成为一种固定结构。如：There is no telling whether he will come this morning.
