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 are fantastically 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 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. From the first 2 paragraphs, we can learn that _________.
| A．plants can do nothing against their enemies |
| B．chemicals are quite useful for plants to survive |
| C．an antelope can always run away from a strong lion |
| D．leaves, roots, flowers and fruits of plants are poisonous |
If animals eat one Golden Wattle tree’s leaves, the tree can________.
| A．kill the animals with a special smell |
| B．tell other trees to come to protect it |
| C．warn other trees against the animals on the phone |
| D．send defense messages to the neighboring plants |
The underlined word “herbivores” in the 5th paragraph probably means animals which _____.
| A．produce poison | B．live on small animals |
| C．like to eat rabbits | D．feed on plants or grass |
The last paragraph of the passage suggests that this kind of defense system is ________.
| A．bad for animals | B．good for forests |
| C．helpful to some animals | D．harmful to forests |
The passage is mainly about __________.
| A．the examples of protecting forests |
| B．the balance between animals and plants |
| C．the ways of plants fighting against enemies |
| D．the relationship between lions and antelopes |

Beautiful scenes of paradise(乐园), wild animals, silly pictures—you can find them all in one place. Where? On a post card! Have people always sent post cards? No. Before post cards, people liked sealed(密封的) letters.
The idea for the first decorated(装饰) post card came to John P. Charlton in 1861.He thought a simple card with decorations would be a great way to send a note. Then in the late 1800s, post cards with pictures appeared. By law, people had to write their note on the front—on the picture! The back was only for the address. Several years later, England allowed a divided-back post card. Then people could write their note on the back left side and put the address on the right. During the early 1900s, the golden age of post cards, picture post cards became a craze of the world. In 1908, Americans alone mailed over 677 million post cards. Today, post cards are the third most popular collection in the world after stamps and coins.

Plants are very important living things. Life could not go on if there were no plants. This is because plants can make food from air, water and sunlight.
Animals and man cannot make food from air, water and sunlight. They get their food by eating plants and other animals. If you look carefully at plants around you, you will find there are two kinds of plants: flowering plants and non-flowering plants.
Flowering plants can make seeds(种子). The seeds are guarded by the fruits. Some fruits have one seed, some have two, three or four, and some have many. But a few fruits have no seeds at all. An example of a fruit without seeds is the banana fruit. Most non-flowering plants do not grow from seeds. They grow from spores(胚芽). Spores are very small. Some spores are so small and light that they can float(漂浮) in the air. We may say that spores are quite the same as seeds. When these spores are all on wet and sandy places, they usually grow into plants.
