One day, a tramp (流浪汉) was sleeping on a park bench, satisfied with the afternoon sunshine. A couple walked by. The man stopped, woke the tramp up, and asked him, “Excuse me. ___you have the time?” the tramp replied, “I’m sorry---I don’t have a watch, so I don’t know the time.” The man apologized and walked away with his wife.
The tramp lay down and went back to sleep. Just then, a woman, ______ was out walking her dog, shook the tramp’s shoulder until he woke up, ___said, “I’m sorry to trouble you, but do you happen to know  the time?” The tramp was a little annoyed at being woken up again, but he politely told the woman he didn’t have a watch and had no idea ______ the time. After the woman left, an idea occurred to the tramp. He opened his bag and took out a pen and a piece of paper. He wrote down with all his strength, “I do not have a watch. I do not know the time.” He then hung the paper round his neck thinking that nobody would hold him back in his sleep. Fifteen minutes ___, a policeman noticed the tramp and the sign around his neck. Out of a sense of responsibility, he woke the tramp up and said, “It’s 2:30 p.m.”
