Do you often think of your parents? You may say, “Of course, I    . I buy a gift for my mother on Mother’s Day and on Father’s Day I give my father a gift, too.” But what about the other days of the year?
I have a friend. She   in Shanghai and her parents live in another city. One day I went to see her. We talked with each other happily. Then she wanted to   her parents. So she dialed（拨号）the number, but then she put down the phone. After about fifteen minutes, dialed the number again. “Hi, Mom…”
Later I asked, “   did you dial the number twice?” She said, “My parents are old and slow(慢) . They    get to the telephone quickly. I always do so when I call them     I want to give them enough time to answer the call.”
My friend is a    girl. She is always thinking about her parents. You also want to be a good child, right? Please always remember    think of your parents, not just on some important days.
