They bark（犬吠）all day and all night, and I can’t get a good sleep.”“I have good news for you,” the doctor said, taking out a small bottle. “Here are some new sleeping pills（安眠药）that work like a dream. A few of these and your trouble will be over.”“Great, thank you.” the woman was very glad to go back home with the pills.A few weeks later, the woman came again, looked worse than ever. She said, “Doctor, your pills are not good at all. I’m more tired than before.”“I don’t understand how that could be,” said the doctor, shaking his head, “Those are the strongest pills on the market.”“That may be true,” answered the woman, “but I’m still up all night running after those dogs and when I finally catch one, it’s hard to get him to eat the pills.”51.

Man gets his food by eating plants and animals, too. So animals and man need plants in order to live.
