Reading：The Frogs and the Well
Two frogs lived together in a marsh. One hot summer the marsh dried up, so they had to leave it and look for another place.
They soon found a deep well.
One of them looked down and said to the other, "This is a nice cool place. Let's jump in and settle down here."
The other frog was much wiser. He replied, "Don’t be so fast, my friend. If this well dries up like the marsh, how should we get out again?"
