题目列表(包括答案和解析)
There is a zoo mour city. My parents often take me there on holidays. I like animals. I have a lot of
toy animals in my room. In the zoo, I can see tigers, elephants, monkeys, pandas , bears , snakes(蛇) and many other animals. Some animals are friendly, but some are not. Tigers, bears and some snakes are dangerous(危险). That is why they have to stay in cages. But I don't think it's good for animals to stay in cages. They should be free(自由). The animals in cages can't be happy.
Tigers usually live in forests and mountains. They can run very fast. They catch and eat small animals
like rabbits (兔子)and deer(鹿),but now they live in small rooms. They have nothing to do every day. So
they walk round and round in the cages, and they want to get out. When they are tired(累了),they sleep.
I feel(感到)sorry for them.
I think the most interesting animal in the zoo is the dolphin. I like watching them swim and jump. They swim fast and they jump very high. They can play with a ball. They can stand up and walk on water! They are very friendly to people. If you fall into(掉进)the water and can't swim, they may (可能)come up to
help you.
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 off enemies.
Over millions of years, plants have developed their own defense system (防卫系统). Chemicals(化学物) are fantastically used by plants to survive . 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 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 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, 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.
