A true friend is always helpful. I didn’t believe it   36  one thing happened to me when I was in Grade 7.

Li Jie was one of my classmates. He and I were also neighbours. He always listened to his mother   37  I didn’t like listening to my mother. I didn’t think it was necessary for  38  to teach me anything. Li Jie knew all about that but he said   39  to me.

One weekend, Li Jie invited me to watch a film. I liked films very much so I went to the   40  with him happily. The film was about the love between a   41  and her son. After watching it, I began to know how great the love of the mother was. I felt   42  that I didn’t listen to my mother before. I decided to think more about my mother than about   43 . After I told that to him, Li Jie smiled and said, “It’s really necessary for you to watch such a film. That was a good choice (选择) for both you and me.”

Suddenly, I knew   44  he invited me to watch the film. Just at that time, I knew a true friend is always   45 .
