一天，小明和他的朋友小华一起去了英语讲座。讲座上，老师讲了一个有趣的小故事。

故事是关于一个小男孩和他的爸爸去钓鱼的。小男孩非常喜欢钓鱼，但他的爸爸却不太会钓。他们找了一个非常漂亮的湖泊，准备开始钓鱼了。

小男孩拿起钓竿，很快就钓到了一条大鱼。他非常高兴，但他的爸爸却不知道如何处理鱼。小男孩告诉他，他需要把鱼放回水里，因为这是一条不能吃的鱼。

爸爸问：“你怎么知道这是一条不能吃的鱼？”

小男孩回答道：“因为这是一条英国人。”

这个故事引起了讲座上的一片笑声。老师解释说，这是因为在英语中，“这是一条英国人”与“这是一条鲈鱼”（perch）在发音上非常相似。

小明和小华也觉得这个故事很有趣。他们回家后，小明向他的父母讲述了这个小故事。他们也笑了起来，因为他们也能够听出这个词语的双关意义。

English Story with Translation and Dialogue:

One day, Xiaoming and his friend Xiaohua went to an English lecture together. During the lecture, the teacher told an interesting story.

The story was about a little boy and his dad going fishing. The little boy loved fishing, but his dad didn't really know how to fish. They found a beautiful lake and started fishing.

The little boy picked up a fishing rod and soon caught a big fish. He was very happy, but his dad didn't know how to handle the fish. The little boy told him that he needed to put the fish back in the water because it was an inedible fish.

The dad asked, 'How do you know this is an inedible fish?'

The little boy replied, 'Because it's an Englishman.'

This story caused a lot of laughter during the lecture. The teacher explained that this was because in English, 'this is an Englishman' sounds very similar to 'this is a perch.'

Xiaoming and Xiaohua also found the story very interesting. When they got home, Xiaoming told his parents the story. They also laughed because they could hear the double meaning of the word.
