单选题 "After a confused silence, the speaker attempted a weak reply only to halt midway to confer with his assistant and finally to admit mat he had made a mistake. " The two infinitive phrases after "midway" are used to________.
【正确答案】 A
【答案解析】不定式用法题。动词不定式作状语时，可以用来表示动作的目的、结果、原因、条件和方式。结合句子意思可知，“中途停下”是为了可以“与助手商议”，而商议的结果是“承认他犯了一个错误”。综合来看，midway之后的两个不定式表达的是“中途停下”的目的。故A为答案。
