四、阅读理解
Johanna loved strawberries. They were her favorite fruit. Last Saturday, she went to a farm to pick some. It was her first time. Before that, she had always bought strawberries at the store.
When Johanna arrived at the farm, she was surprised. Strawberries did not grow on trees! They did not even grow on big bushes. They grew on something like vines (藤). And there were so many of them.
Johanna was given a basket. She could pick as much as she wanted. The more she picked, the more she would have to pay. She wasn't sure how much to get. She started filling her basket. She ate some strawberries while picking them. They were so big and juicy! And the sun had made them sweet.
The basket was quickly filled. Johanna took it to the farmer to pay for it. She handed him a ten-dollar bill (钞票) and got back one dollar. “How cheap!” Johanna thought.
When she got home, Johanna quickly cleaned the strawberries and put them in the fridge. Some, she could use to make jam (果酱). Others, she could eat fresh or with sugar on top. She thought about crushing (压碎) some over some ice-cream, or freezing some for later use. There were so many things to do with strawberries, and they were all delicious!
