The Doctor Visited Me
About a month ago I was at a lesson working with my textbook Suddenly I felt really ill.I felt very cold and I had a headache and my eyes hurt.My teacher phoned my mother.She came soon,took me home and called a doctor.
In the afternoon the doctor visited me.She examined me throat,listened to me heartan and lungs,looked at my eyes and ears.In the end she said,Well it`s a bad cold.You have to stay in bed for a week.She wrote me a prescription for some medicines.She told me to take pills three times a day.She also asked my mum to give me hot milk with butter and honey or hot tea with raspberries.
My mum went to the chemist`s and bought the medicines for me.I followed the doctor`s advice and soon I felt much better.My friends were glad to see me at school again.Переведите пожалуста!!!!!!!!!!!!!!!!!!!!!!!!!!!************пожалуста умоляю
