The students in Dave's class are studying English history. one day the teacher said to them, "hey, children, we are going to Conway by bus on Friday. there is a castle called Conway. we are going to visit it." The children were very happy to hear this."Now, does anyone have a problem?" The teacher asked."How old is that castle, sir?" Dave asked."About 700 years, Dave," the teacher replied.On Friday, the children came to the school at 9 o'clock and got on the bus: they visited Conway Castle and then went home."Hello," said his mother when Dave got home, "do you like the castle, Dave? ""Not really," Dave replied. "Those fools built the castle too close to the railroad.

　　戴夫那个班的学生正在学习英国历史，有一天老师对他们说：“喂，孩子们，星期五我们要坐公共汽车到康维 去，那有一座叫康维的城堡，我们要去参观。”孩子们听到这话非常高兴。

　　“现在，有谁有问题吗？”老师问道。

　　“那座城堡有多少年历史了，先生？”戴夫问道：

　　“大约700年，戴夫：”老师回答说。

　　星期五孩子们9点钟来到学校上了公共汽车：他们参观了康维城堡：然后各自回家。

　　“喂，”戴夫到家后妈妈问他说：“你喜欢那个城堡吗，戴夫？"

　　‘不怎么喜欢，”戴夫回答说，“那些蠢人把城堡建造得离铁路太近了。
