When I was 8 years old, I once decided to run away from home.

You didn’t wear anything when you arrived.” This really angered me. I tore my clothes off—shoes, socks, underwear and all—and 40 , “Can I go now？” “Yes,” Mom answered, “but once you close that door, don’t expect to come back.” I was so 41 that I slammed (砰地关上) the door and stepped out on the front porch. 42 I realized that I was outside, with nothing on. Then I noticed that down the street, two neighbor girls were walking toward our house. I ran to 43 behind a big tree in our yard at once. After a while, I was 44 the girls had passed by.

Let me in!” The door inched open and Mom’s smiling face appeared. “Did you change your 47 about running away？” she asked. “What’s for supper？” I answered. (277 words)
