单选题 Bobby Adams was very quiet as Dr. Smith examined him. The doctor looked at the boy"s throat (喉咙), took his temperature (量体温) and listened to this heart. At last, He asked Bobby"s mother a few questions.
"When did Bobby begin to feel ill?"
"This morning when he got up. He said he felt too sick to go to school today."
"What did he eat for breakfast?"
"He had orange juice, two pieces of bread and milk."
"I see." The doctor asked Bobby, "How are you feeling, my boy?"
Bobby answered, "Terrible (很难受). I think I"m going to die."
The doctor said, "You won"t die. In fact, you"ll be fine by dinner time."
"Oh, Doctor! Do you really think so?" Bobby"s mother looked very glad.
Dr. Smith answered, "Mrs. Adams, your son has a sickness that is very common (常见的) to boys at a time like this. It comes and goes very quickly ."
Mrs. Adams said, "But I don"t under sand."
"Today," the doctor told her, "The most important baseball (棒球) game of the year is on television. If Bobby feels well enough to watch television this afternoon, and I think he does, he will be fine when the game is finished. It"s the only cure (疗法) I know for this sickness. Now, if you"ll excuse me, I must go across the street to see the Morton"s boy, Alfred, he seems to have the same thing Bobby has today."
