Have you taken your temperature?
Yes, and it is 37  C.
Well, open your mouth and let me have a look. It is nothing serious. You haven't got a fever. But you should take the medicine and need have more rest recently. When you feel well, you could take more exercises, or play sports like basketball, running, and swimming. And eating healthy food, having more fruits and vegetable and drinking milk are good for your heath.
Yes, I see. Thanks a lot.
