The lady with the white fence（篱笆）taught me to leave the gale to life open.. .

My husband died in an accident and I became very angry. I hated being alone. One day, as I was　 43　 down a busy street, I suddenly noticed a new fence around a house. I pulled off to really watch it. It was such a good 　44　 that I was deeply touched. I could not send 　45 away. The fence still smelled of fresh paint.

“Hello!" I came up and said to a lady in the back garden, “I came to see the fence. It's so beautiful!"

“Oh! The fence is not there for me," the lady explained to me in a calm voice, “I live alone. 46　so many people pass by every day, and I think they may be pleased to see something really attractive. 　　47　 stop like you and come up to have a chat. "

"But weren't you sad when they expanded (拓宽) the road and everything changed so much?"

like happens to us, we have two choices—to become a 　 49　 person or to become a better person."

Her reply changed my life. I carefully left the gate open and drove on 50 　a new feeling inside me. I could not tell 　51 it was, but I could feel the thick stone wall around my angry heart breaking off. And 52 a pretty white fence was built. I decided that I would keep the gate open for everything and everyone that came my way.

　　We sometimes say the lion is “the king of the jungle(丛林)” because it is stronger and more dangerous than the other animals. It can run faster than most other animals and it can hunt(捕猎) the best. The lion is the highest animal in the land food chain. In the sea, the shark is at the top of the food chain. It can swim faster than most other sea animals. It can also use its big teeth to catch other sea animals and eat them.

　　What is at the top of the world's food chain? People are! We are not the biggest or fastest, but we are the cleverest. We could not run faster than most animals, so we invented cars and now we can move the fastest. We could not fight better than a lion, so we invented guns. Now we can hunt the best.

　　People's inventions are clever, but they can be dangerous, too. For example, many years ago in Inner Mongolia, people used guns to kill a lot of wild wolves. The wild wolves usually eat wild rabbits. But in recent(近来的) years, the number of wild rabbits is becoming bigger and bigger because the number of wild wolves is getting smaller and smaller. The wild rabbits competed(竞争) for the grass with the sheep and cows. Much of the grassland became desert because it was seriously destroyed(毁坏) by the rabbits.

　　Remember that we are a part of the food chain, so we are in danger, too! If we protect animals, we are protecting ourselves.
