【简答题】
Several years ago I studied at a university in the biggest city in our country. It’s beautiful but it’s hot in 1 . So I usually returned to my hometown when my 2 began. It is not big, but it’s cool and quiet. I could 3 in the daytime and have a good sleep at night. One day I had some 4 to solve. But I didn’t take the dictionaries home. My father told me Charlie, one of my 5 , had a good library. I went to his house at once. We didn’t see each other after 6 middle school. At first he didn’t recognize me. He 7 me up and down. And then he called out, “Oh, dear! It’s you, Fred!” Of course, we were 8 to meet each other again and talked a lot about our schoolmates and 9 . Later on, he showed me around his library. It wasn’t big but there were a lot of nice books in it. And the dictionaries I 10 were in them too. At last I said, “ 11 you lend some dictionaries to me, please?” “I’m sorry I don’t lend any books to 12 ,” said the young man. “Are you afraid I’ll 13 them?” “No, I’m not. I’m afraid you won’t 14 them to me. Look! All the books are not 15 , but borrowed!”
