Jill and Kate are going hiking with their classmates tomorrow. They want to take some fruit with them. Jill likes oranges and Kate likes apples. When they get to the supermarket, they can’t find any oranges, and the apples are too green. “What are we going to buy now?” asks Kate. “Hey, what’s that big round fruit over there?” asks Jill. “I don’t know. Let’s ask the salesgirl.” “Excuse me. What’s this?” asks Kate. “It’s a grapefruit(柚子),” answers the salesgirl. “Why don’t we buy one?” asks Jill. “OK. We will have a fun hiking and eat a new kind of fruit!” says Kate.
