阅读理解。 Mr Scott is a pediatrician (儿科医生). Almost all the people in the town know him. He is working there for a long time. He is always kind to the children and often plays games with them. The children aren't afraid of him and they think he's a good doctor. One afternoon he is busy. A lot of people have a cold. Now a woman with a baby in her arms comes in. The doctor doesn't know her but he sits down to look over the baby carefully. The baby looks very nervous (紧张). Seeing this, Mr Scott points to the boy's ear, and says, 'Is this your nose, my little friend?' The boy turns to his mother at once and says, 'I think we should find a good doctor!' (     )1.
