—You should be careful when _______.—Yes, I will. I’d like to know when ________ to have a rest. A．driving; stopping B．driving; to stop C．to drive; stopping D．to drive; to stop

Answer 1

B

本题考查非谓语动词。第一空考查现在分词作状语，drive与逻辑主语you为主动关系；第二空为V + 特殊疑问词 + to do结构。句意：——当开车的时候，你应当小心。——是的，我会的。我想知道什么时候停下来休息会儿。
