根据课文内容完成医生与三位病人的对话。 Linda Smith works at the school clinic. Yesterday afternoon, three students visited her office. The first one was Sam, a very fat boy. He said that he had a stomachache. Linda asked what he had for lunch. Sam said that he had 3 big hamburgers and a large box of ice-cream. “What a huge lunch!” said Dr. Smith. “Well, it is nothing serious. Just remember to exercise more and eat less!” Sophie was the second. It was a cold day, but she was in a very short skirt. She looked pale and kept coughing all the time. After a careful check, Dr. Smith said, “You’ve caught a cold. It is not serious. Take the pills three times a day for 3 days. Remember to wear warmer clothes on cold days.” The last was Henry. He hurt his left foot during a football match. Dr. Smith asked him to lie down and put an ice bag on his foot. Henry felt much better. Dr. Smith smiled, “OK, go home and use ice on your foot for 5 minutes each hour for the first 2 days. Stay in bed for a week.” What a busy afternoon!
