Do you often think of your parents? You may say, “Of course, I   小题1: . I buy a gift for my mother on Mother’s Day and on Father’s Day I give my father a gift,   小题2:.” But what about the other days of the year?

I have a friend. She 小题3: 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  小题4:  her parents. So she dialed（拨号）the number, but then she put down the phone. After about fifteen  小题5: , she dialed the number again. “Hi, Mom…”

Later I asked, “ 小题6: did you dial the number twice?” She said, “My parents are old and slow(慢) . They  小题7: get to the telephone quickly. I always do so when I call them  小题8: I want to give them enough time to answer the call.”

My friend is a   小题9: girl. She is always thinking about her parents. You also want to be a good child, right? Please always remember  小题10: think of your parents, not just on some important days.
