Passage 1 Some foods have names that make good sense. Take an orange, for example. Its color is orange. So it seems only right to call the fruit by that name. But what about the peanut? True, it is a kind of pea. Like other peas, a peanut grows in a shell, or pod. But a peanut is not a nut. It might seem like a nut. After all, it is small, round, and hard. But a peanut is not part of the nut family. So the name peanut is really not the best name for the food! Can you think of a better name for the peanut? Did you ever eat a pineapple ( 菠萝 ) ? You might have liked its taste. But how good is its name? A pineapple is neither a pine nor an apple. It looks like a large pinecone. But it is not in the pine family. It is not in the apple family, either. What may be a better name for a pineapple? You may enjoy grapefruit. But its name is not the best. Yes, it is a fruit. But it is not in the grape family. Grapes grow on vines. Grapefruit grow on trees. What does all this prove? The names of foods can be food for thought!
