更新1: 顺便请问下面这句是什么意思
被句首的do搞得看不懂.. Do I need the exact change?
How is the new technician doing? 的答案应该是 He's doing a great job。原因是问题是问做得怎样 (how) 而不是做甚么 (what)。 Do I need the exact change? 是问我是否要带备正确数目。这句的背景应该是某人去某个地方（或坐车），而该地方的入场费（或坐车的车费）不设找续，所以要带备 exact change。
Do I need the exact change?我要带准确数目的零钱吗? Answer: (1) You need the exact change要带零钱 (2) You don't need the exact change as there will be a person to break a dollar. 有人找续
My wer is the same as wer no. 2. How is the new technician doing ? Does he work out or does he fit for his job? Correct wer is he's doing a great job. What is he repairing? He's reapiring the fax machine.
how 问他做事的表现如何? He's doing a great job.他表现很好。 2010-04-04 14:03:12 补充： He's repairing the fax machine.他正在修理传真机。
