问题
选择题
—— Do you think you can repair this machine without help?
—— _________. This is not the first time for me to do so.
A．Don’t worry.
B．All right.
C．Don’t mention it.
D．No problem.
答案
答案：A
题目分析：交际用语，重在理解语境，对方是在安慰他别担心，根据句意：你认为你不用帮忙能够修理这个机器吗？ 别担心，这不是我第一次这样做。故选A
点评：本题极易受中文影响而选D，no problem只有用于对方要求你做什么事情是才可用它。同理一下这个题也不能用No problem.只能选Go ahead.
— Is it all right if I sit here?
— _______
A. Yes, it is.
B. Go ahead.
C. Never mind.
D. No problem.
