Doctor：Come in,please.I'm Dr.Evans.
Carl：I'm Carl Mathews.
Doctor：Have a seat.What seems to be the problem?
Carl：I've lost a little weight recently,and I don't seem to have as much energy.My head and stomach were killing me yesterday.I might have had a fever,and I thought I ate something bad because I had the runs.
Doctor：（checking Carl's file） Everything was fine your last checkup 3 months ago.Are you eating OK?Do you bring anything up?
Carl：I'm eating fine,more or less.Last night,I thought I was going to vomit.
Doctor：Do you sleep well?
Carl：A little fitfully sometimes.This morning,I felt too sick to even get out of bed.
Doctor：（after checking Carl's heartbeat,blood pressure,and temperature） Everything seems to be OK.Any other symptoms?
Carl：No,nothing I can think of.I must say that things have been quite hectic around the office,recently.
Doctor：I think you may have a touch of the flu that's going around.And you do seem a little tired.I'll give you a flu shot and I recommend you take some vitamin supplements.Try to take it easier at work for a while,too.
