DIALOGUE АTracing a Fault

Nick: Peter, I know you are a good driver. I would like you to have a

look at my car.

Peter: What's wrong with your car?

N.: I don't know.

P.: Let me have a look. When did you have your plugs checked?

N.: Three days ago. I thought I had run out of fuel but the tank is half full.

P.: The carburettor is in order but the engine is misfiring. I guess

the battery has run down. It needs recharging.

N.: Too bad.

P.: Don't get upset about it. It won't take you long to have your

battery recharged.

N.: Do you really think so?
