1.We have always been warned of the dangers of the forest fires. They cause1to a forest. They kill many plants and animals in an eco-system, which is a group of living things and their environment. But have you ever heard of a forest fire that can be2for a forest?
2.People start some of the fires with special reasons to actually do well to the eco-system.
3.In fact, fires are a natural part of any eco-system. Without fires, the oldest and largest trees would stop sunlight from reaching the forest floor. Fires can3some of these old trees. When the trees die, they provide something good for the earth. New trees can grow strong and healthy in their place.
4.Some trees even need fires to grow. These trees hold their seeds(种子) inside. Heats from a fire allow the coat of the seeds to open up. Then the seeds fall to the ground and have the4to grow.
5.Scientists, who know about nature’s needs, start some of these fires, called controlled burns. A fire is started and kept under control. This way, the fire does not spread out of the area or5a large space of the forest. Fires can be dangerous for animals. Even when animals continue to live after forest fires, they can go hungry6their food has been damaged in the fire. Small, controlled fires mean that animals will not have to move far to find food. After some time, small plants begin to grow. Animals return soon after the plants return. This7makes an eco-system.
6.So the next time you hear about a forest fire, think about the good as well as the bad. It may take a new eco-system a while to return, but it will likely come back stronger and healthier than ever.

I was now five, and still I showed no much interest in things except with my toes(脚趾). I could not look after myself,1my father took care of me. I used to lie on my back all the time in the kitchen. I was2, imprisoned(监禁) in a world of my own, unable to communicate with others.
Then, suddenly, it happened on the afternoon of a cold December day. All the family were gathered round the big kitchen fire. Mona and Paddy were drawing funny animals, using a bright piece of yellow chalk. It was the chalk that3me so much. I had never seen anything like it before.
Suddenly, I wanted to do what my sister was doing. Then without thinking or knowing exactly what I was doing, I4out and took the chalk out of my sister’s hand, with my left foot. It is a puzzle(迷惑)to many people as well as to5. I held the chalk tightly between my toes and made a wild scribble(乱涂)with it on the board. Next moment I stopped, not knowing what to do with the chalk next, hardly knowing how it6there. Then I looked up and realized that everyone was looking at me7. My mother came in. Her eyes looked from my face down to my8, then she took another piece of chalk from Mona, and drew the single letter “A” on the floor in front of me. “Copy that, Christy.” She said. I tried to do the same action, but I9. “Try again, Chris.” she whispered in my ear. I tried another two more times. I drew one side of the letter, then the other. It looked ugly, but I10to make it finally. I had done it! True! I couldn’t speak with my mouth, but now I would speak through something more11than spoken words. That one letter was my12to a new world, my key to mental freedom.
