阅读短文，根据短文内容，从短文的五个选项中选出能填入空白处的最佳选项。 有一个选项为多余选项。 A funny thing happened to my sister Tina last month. She lives in Japan and teaches English. In Japan, people don’t usually wear their outdoor shoes in the house or in school, and a lot of buildings have places for shoes. So her school ahs a special place for shoes. 小题1: Tina teaches English in the evening. One Friday, she went to school, and she put her shoes in the shoe box—as usual. Then she had an interesting spoken English class with her students. 小题2: But to her surprise, her shoes weren’t in the box. There was only one pair of those there, and they weren’t her hoes! She had to get home in a hurry. 小题3: On Monday, at her next English class, her shoes were in a shopping bag on her desk! There was a note that said, “I’m so sorry. I took your shoes by mistake!” 小题4: Somebody felt a lot of shame!
