The vet looked over the cow. "She's certainly ill," he said, "and she needs to take some very strong medicine."

    He took a bottle（瓶子） out of his box, put two pills（药丸） into his hand and said, "Give her these. The pills should make her better” How should I give them to her?” the farmer asked.

    The vet gave him a tube (管子)and said, "Put this tube in her mouth, then put the pills in the tube and blow. That will make it."

       公与之乘，战于长勺。公将鼓之。刿曰：“未可。”齐人三鼓。刿曰：“可矣。”齐师败绩。公将驰之。刿曰：“未可。”下视其辙，登轼而望之，曰：“可矣。”遂逐齐师。

       既克，公问其故。对曰：“夫战，勇气也。一鼓作气，再而衰，三而竭。彼竭我盈，故克之。夫大国，难测也，惧有伏焉。吾视其辙乱，望其旗靡，故逐之。”
