“井底之蛙”的英文简短表达为“frog in a well”。这个英文短语直接对应了中文成语“井底之蛙”的含义，形象地描绘了一只生活在井底的青蛙，由于视野受限，只能看到井口那么大的一片天，因此它的认知和理解也是有限的。这个英文短语同样传达了狭隘、见识短浅的意思，并可以在多种场景中使用。
以下是一个简短的英文版井底之蛙故事：
The Frog in the Well
Once upon a time, there lived a frog in a well. The frog had never seen the world outside the well and thought it was the whole universe. One day, a turtle came by and told the frog about the vast ocean, high mountains, and endless plains he had seen. The frog was amazed and asked the turtle to take him out to see these wonders. The turtle agreed and pulled the frog out of the well. The frog was astounded by the vastness of the world and realized how much he had been missing. From that day on, the frog was never content to stay in the well again.
这个故事简短地概括了井底之蛙的寓意：不要局限于自己的小世界，要拓宽视野，了解更广阔的世界。同时，“frog in a well”这个英文短语也可以用作警示，提醒人们不要像井底之蛙一样见识短浅。
