【题目】--- I tried to make John ________ his mind but I found it difficult.

--- Well, I saw you ________ that when I went past.

A. changed; doB. changes; doingC. change; doing

Answer 1

【答案】C

【解析】

句意“-我尝试着让约翰改变他的想法，但是我发现这是困难的。-哦，当我路过时，我看见你正在做那件事”。第一空处根据make sb do可知，空处用原形；第二空处根据see sb doing可知，表示“看到某人正在做”，故选C。
