When you watch TV programs about wild animals, it is surprising to see how an antelope(羚羊) can run away from a strong lion. In the wilderness, everyone has his own way to protect himself. Even plants have their own ways to fight against enemies.

Over millions of years, plants have developed their own defense system(防卫系统). Chemicals are used by plants to survive(幸存). By making their leaves, flowers, roots and fruits poisonous(有毒的) to enemies, plants can fight back.

One such plant is the Golden Wattle(金合欢花) tree. The British scientist David Cameron has found when an animal eats the tree's leaves, the amount(数量) of poison increases in the other leaves. “It's like the injured leaves telephoning the others to fight together against the enemy，” he said.

The tree also sends defense messages to its neighboring plants by giving out a special smell. Golden Wattle trees in the nearby 45 meters will get the message and produce more poison within 10 minutes. Now, if an enemy eats too many of the trees' leaves, he will die.

Every kind of plant or tree is good at producing a special set of chemicals. Herbivores(食草动物), like rabbits, can safely eat the leaves of one tree, but they may be poisoned by its neighbor.

In this way, plants have not only developed their own defense system, but also shared it with others. This makes it impossible for a single animal to destroy even a small area of forest. 根据短文内容，判断下列句子正误，正确的用“A”表示，不正确的用“B”表示。 11．Plants can fight against enemies by using chemicals.

12．American scientist David Cameron has found how the Golden Wattle tree fights together against

根据短文内容，回答下列问题。

(2017·湖南永州中考)It was a sunny day and I walked back home after school. When I stood in front of the door, I was shocked to find that the key had disappeared from my pocket. It was a disaster for me, because I only had one key and my parents were gone for several days.

I walked around the community, hoping to find the lost key. But I couldn't find it. I called my mum and she told me to go to my aunt's home. My aunt lives in another building of our community. I was sad, but I had no choice. The next morning, when I was going to school, I saw something shining on the window of the security hut(保安亭 ). It was my key. “unbelievable！” I was quite surprised as I held the key in my hands.

“Is that yours, kid？” the old guard asked.

“Yeah. I lost it yesterday. Who sent this？”I replied. The old man said，“I don't know, someone picked it up last night.”

To pick up a key from the ground and take it to the security hut is not something special, but it meant so much to me. I cannot express my thanks to the person who found my key. But I can pass on his or her kindness by following his or her steps to help others. 29．How many keys did the writer have?
