一篇初中阅读理解
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 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,could you tell us how to get to the North Church,please?”
“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 Englishmen said,“You can't miss it.”
难句注释
“Is everything in Boston three blocks and a left turn ”
“在波士顿到每个地方都是走三个街区,然后向左拐吗?”
请问：这是怎么回事?他们为什么要连续走三次三个街区并拐三个弯?是被捉弄了吗?
我问的不是文章的翻译
另外二楼的解释肯定吗？

我以前看过这篇,其实是幽默带点小讽刺,意思是说当地人也并不清楚路到底怎么走,只是别人问路,他们习惯于说"Go three blocks and turn to your left"
