  Two Englishmen were in Boston for a visit. One morning, they went out to

look for a famous church, but they didn’t know how to get there. They stopped a

man and asked.  

  "Excuse me, can you tell us the way to the North Church?"

  "Go three blocks (街区)and turn to your left. he said,"you can't miss it."

        So the Englishmen walked three blocks and turned to their left. But they

didn't see any church. They then asked a second man. 

        "Excuse me , but we're trying to find the North Church." 

         This one said, "Go three blocks and turn to your left."But again they

couldn't find the church. In the end they asked a third man,"Excuse me, please,

could you tell us how to get to the North Church?"

         "Go three blocks and turn to your left, you can't miss it." 

         They walked three blocks and turned to their left for a third time. This time

they found the church.

         "Is everything in Boston three blocks and a left turn?" they asked

themselves.

         Just then a man walked over to them."Excuse me."the man said,"Where is

the East Park? can you tell me?"

        "Go three blocks and turn to your left,"one of the Englishmen said,

  "you can't miss it."
