Dave's class at school were studying English history,and one day their teacher said to them,"Well,boys,on Friday we're all going to get on a bus and go to Conway.There's a beautiful castle there,and we're going to visit it." The boys were very happy when they heard this.
"Now,has anybody got any questions?" the teacher asked.
"How old is the castle,sir?" Dave asked.
"It's about seven hundred years old ,Dave ," the teacher answered.
"What's the name of the castle,sir?" another boy asked.
"Conway Castle," the teacher said.
On Friday the boys came to school at 9 o'clock and got into the bus.They visited Conway Castle,and then they came back and went home.
"Well ," Dave's mother said to him when he got home ,"did you like the castle,.Dave?"
"Not very much," Dave answered."The stupid people built it too near the railway."
这篇文章的结尾是什么意思?

答案

Dave参观完Conway城堡后,他妈妈问他喜欢那里不,他回答不是很喜欢,因为那些蠢家伙把城堡建在铁路旁边.
意思：
这个笑话说的是DAVE认为建城堡建的太靠近铁路了,所以不喜欢.但是他却忘记城堡是700多年前的,那时候根本没有铁路.
