狮子和兔子
The Lion and the Hare
狮子看到一只熟睡的兔子，正想把她吃掉时，忽然瞥见有一头雄鹿匆匆经过。于是，狮子就丢下兔子去追雄鹿。兔子被响声惊醒，急忙逃走了。过了好长时间，狮子仍然无法顺利追赶到雄鹿，只好返回来寻找在睡梦中的兔子。当他跑回原来的地方时，发现兔子已经逃走了。两手空空的狮子失望地说：“我真是自作自受啊！竟然放弃可以轻易到手的猎物，而去追求希望渺茫的东西。”
要把握住眼前的机会。
A Lion came across a Hare，who was fast asleep. He was just in the act of seizing her，when a fine young hart trotted by，and he left the Hare to follow him. The Hare，scared by the noise，awoke and scudded away. The Lion was unable after a long chase to catch the Hart，and returned to feed upon the Hare. On finding that the hare also had run off，he said，“I am rightly served，for having let go of the food that I had in my hand for the chance of obtaining more.”
