“I forgot. You’ve never seen a supermarket before, have you,
Jimmy?”
I shook my head no.
“A trading post in the pueblo only shows you a small part of the world. This store speaks of a world that is a very big place.”
“So I should just forget where we come from, is that it?”
“No. Carry it with you, so that you may be always in both worlds, large and small.”
“So it’s big, so what! I’d rather be in a trading post any old day. Maybe they only have one kind of apple, but they are all ripe!” While I was saying that, I was watching a woman putting the green apples into a bag. “That woman is being cheated because she doesn’t know the apples aren’t ripe.”
Grandfather laughed. He also put about half a dozen of the green apples in a bag.
“You’ll get a stomachache if you eat green apples,” I said.
Grandfather looked as though he were going to laugh again, but he didn’t.
At the cash registers, Grandfather paid his money. Nobody said much. Maybe everybody in a city always acted like strangers. Maybe that was how people got along with each other here.
When we got outside, Grandfather reached for one of those green apples.
“Feel like sharing an apple with me?” He used a small knife to cut the apple in half. He offered me one piece.
I was hungry, but I said no.
Grandfather chewed the other piece, making a great show of how good it tasted. “Not afraid of an apple, are you?”
I didn’t know why he was making such a big deal over an apple, so I took it. I bit into it and it was juicy and sweet.
“It’s not a trick. I thought it was when I first saw them, too. But it is this kind of apple, it gets ripe but it stays green.” He finished his half of the apple.
“It tastes pretty good,” I finally admitted. A green apple that was ripe! It just didn’t seem possible somehow.
“You’re going to see lots of new things here. Just try not to forget the old things you already know and you will do well,” said Grandfather.
50. Where did Jimmy go with Grandfather?
A. To a hotel. B. To a garden. C. To a supermarket. D. To a restaurant.
51. Jimmy thought the woman was cheated because he believed __________.
A. the apples weren’t ripe B. people laughed at her
C. she was a stranger here D. she didn’t get along well with others
52. What can we learn from the story?
A. We should follow the rules in public.
B. We should be ready to share with others.
C. We should try to learn from the old people.
D. We should keep the old and be open to the new.
