Mr White moved to another town. He had a cold one day. So he went to see a doctor. He sat down in the
waiting room and looked around. The doctor's diploma (证书) was hung (挂) on the wall. Suddenly Mr White
remembered that there was a classmate with the same name in his class at the college (大学).
When he went to see the doctor, he remembered a young, nice student, but now he was sad to see an old
man with gray (灰白的) hair. He said to him, "Good morning, Doctor. Did you go to King's Medical College ?"
The doctor answered, "Yes, I did."
"Were you there from 1975 to 1979 ?" Mr White asked.
