Why don’t you drink water as the book told us?
Crows Drink Water
There was only a little water in a bottle which had a long and narrow neck. A fat crow came to the bottle and drank the water by a straw. He was enjoying the water when another thirsty crow went by. Accustomed (习惯于) to the way of drinking water taught in books, the thirsty crow was very surprised. He asked the fat crow, “Why don’t you drink water as the book told us?” The fat crow replied,“Because this method can make me drink water faster.”
