What will the house look like in the future? Could it have gardens on its walls, or a pool with fish for dinner? Architects（建筑师） believe that they are all possible. The only thing for sure is that the houses will be as green as possible.

The tree house

Many architects in the world would like to build a “tree house.” Like a leaf, the surface of the house collects sunlight during the day. The energy can be used to heat water, produce electricity, and even create fresh air for the home. The “root” (根) of the house is deep under the ground. It uses the soil (土壤) to keep the home’s temperature.

 The Lizard house

Like a lizard (蜥蜴), changing color with the weather is the most important design of a lizard house. When it’s in the bright sun, the cover of the house will turn dark to protect it from strong heat. During dark days, it turns white and takes in as much light and heat as possible to produce energy.

 Meals at home

This design is perhaps as much about the future of food production as architecture (建筑风格). It has gardens on the outside wall of the house. People can plant tomatoes, carrots and green tea on them. So every day in the morning, you just need to walk outside and collect your meals.

Learning from the past

Looking to the future isn’t the only way to be green. Sometimes, ancient techniques (古老的技术) can also help cut down energy use. For example, a chimney (烟囱) can be a useful air conditioner because it is easier to flow out hot air from the chimney.

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.

A big, mighty(高大的) tree stood in a forest. Its branches(树枝) spread out and its roots (根) went deep in the earth. A lot of people came here to have a rest under it. And a lot of birds stood on its branches to sing and dance. The big tree was very proud all the time.
At the foot of the tree, there was a little plant. The plant was thin, and seemed to be blown down by any of a little wind.
One day, the two neighbors were having a little chat.
“Well, little one,” said the tree to the plant, “why not put your feet deeply in the earth, and raise your head high in the air as I do?”
“I see there is no need to do so,” said the plant with a smile. “In fact, I think I may be safer in this way.”
“Safer?” said the tree. “Are you safer than I am? Do you know how deep my roots are in the earth and how strong my branches are? Who can possibly pull me out by the roots or bow my head to the ground?” And the tree didn’t want to say anything to the weak plant.
But the tree was to regret its words very soon. One evening, a great hurricane(飓风) came. It blew the trees off their roots and almost destroyed the forest completely. It uprooted（将……连根拔起）the mighty tree and blew it away with great force.
When the storm had gone, the villagers living nearby came to check the damage. The mighty tree lay on the ground, but the little plant still stood there.

Monkeys are clever and lively, but they are naughty and greedy (贪婪的) as well. Whenver they find delicious food, they will eat enough.  What’s more, they will take it when they leave. They have suffered (吃亏) a lot because of this. But they never change this way.

In India, people use monkey’s greed to catch them. Do you know how they can catch monkeys? Here are some instructions.

◆               Make a hole in a big pumpkin (南瓜). The hole must be just right     ----neither too big nor too small.

◆               Put some jujubes (枣) in the hole.

◆               Leave the pumpkin under a tree. Make sure there are some monkeys in   the tree.

◆               Hide yourself and watch the monkeys.

As soon you leave, the monkeys can’t wait to come down to the pumpkin. When they find a hole in the pumpkin, they don’t know what’s in it and one of them can't help putting its hand into the hole to find what on earth there is. When it touches the jujubes, it will clench (攥紧) some of them in its hand. As a result, it isn’t able to take its fist (拳) out of the hole. You can’t come close until this time. Will the monkey drop off the pumpkin? Don’t worry. It prefers the pumpkin than its life. It will run with the pumpkin, clenching its fist more tightly. In the end, it is caught helplessly.
