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.

One day, a farmer was walking along a road with his son Thomas. The father said, “Look! There's a horseshoe. Pick it up and put it in your bag.” Thomas said, “It isn't worth the trouble.” His father said nothing but picked it up himself. When they got to a nearby town, they had a rest. There the farmer sold the horseshoe and with the few pennies he bought some cherries.
The father and the son continued their way. The sun was well up in the sky, and there wasn't a house or even a tree where they could have a rest. Thomas felt too thirsty to walk on. At this time, his father dropped a cherry on the ground and Thomas picked it up quickly and ate it. After a while, his father dropped another cherry and once again, his son lost some time in picking it up and putting it in his mouth.
And so they went on. The old farmer dropped the cherries and the son picked them up. When Thomas had eaten up all the cherries, his father said to him, "My dear son, if you had bent down earlier to pick up that horseshoe. it would not have been necessary for you to bend so many times for the cherries.

For years I wanted a garden. I’d spend hours thinking of different things I could plant that would look nice together.
But then we had Matthew, and Marvin, and the twins Alisa and Alan, and then Helen. I was too busy raising them to grow a garden.
Money was not enough. Neither was time. Often when my children were little,one of them would want something that cost too much, and I’d have to say, “Do you see a money tree outside? Money doesn't grow on trees, you know.”
Finally, all the children got through high school and college and were off on their own. I started thinking again about a garden.
Then, one spring morning, on Mother’s Day, I was working in my kitchen. Suddenly, I looked out of the window and there was a new tree, planted right in my yard. There were things blowing around on it. Then I put my glasses on—and I couldn’t believe what I saw.
There was a money tree in my yard!
I went outside to look. It was true! There were dollar bills*, one hundred of them, hanging all over that tree. There was also a note among them, “Thank you for your time, Mom. We love you!”
Later, my children bought me tools, ornaments, a sunflower stepping stone and gardening books. A new page started in my life.
That was three years ago. My garden’s now very pretty, just like I wanted. When I go out and take care of my flowers, I don’t seem to miss my children as much as I once did. It feels like they’re right there with me. Now every year when winter comes, I look out of my window and think of the flowers I’ll see next spring in my little garden. I think about what my children did for me, and I get tears in my eyes—every time.
I’m still not sure that money grows on trees. But I know love does!
