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 (選擇) 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 .

 Today we can see that many people are cutting down the trees in the forests. A lot of        lands have become deserts. If we read newspapers, we’ll learn that the forests on the earth are getting smaller       . We are cutting down large numbers of trees        we need wood and farmland. Some scientists say that there will not be any great forests        20 or 30 years.

What will happen if the forests disappear? A lot of plants will die and the animals will      

their homes. In many places the new farmland will soon look        the old desert. Crops will not grow there. There won’t be enough       , and the weather will get hot and dry. If the climate of the earth changes, life will be        for everyone. Our living environment will become       . More and more rich farmland will disappear. We will suffer a lot from both droughts (干旱) and floods.

It’s our duty        the forests well. Everyone should try his best to make a contribution (貢獻(xiàn)) to taking care of the forests. Stop cutting down the trees and make the world greener!
