5 . A desert is a very dry land where there is hardly any rain. In the day, it can be so hot that you could fry an egg on the ground. But during the night it is sometimes so could that water would turn into ice.
Many desserts are covered in sand. But some have mountains, rocks, or lakes that have dried up in the heat. The Great American Dessert has cliffs (悬崖) that have been made into amazing and beautiful shapes by the wind. The Sahara Desert in Africa is mostly sand. The Australian Desert has red sand.
Sometimes it does not rain for a whole year in the desert. But there is water deep under the ground and some plants have roots that go very deep to find it. Other plants have roots that spread out a long way so they can suck up the rain as soon as it falls. One desert plant is the cactus, which has long, spreading roots. The cactus stores water inside its hard skin. This skin protects it from heat and cold. Camels are a bit like cactus plants! They store water too — inside their bodies. They have special fur which protects them from the sun during the day and keeps them warm at night.
Some other animals live in deserts, too. They have to be very good at seeing and hearing because most of them only come out at night. This is why many desert animals have extra big eyes or ears. A desert fox has bigger ears than a normal fox. A gerbil has huge eye, so that it can see at night. It stays cool in the day by staying underground, like most desert animals.
Some people live in the desert but they always make their homes near an oasis. An oasis is where water comes from an underground river. Near an oasis, people can grow lots of plants and keep animals.
Life is hard in the desert, for people, animals and plants. But desert people like to live there.

6 . 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 wild, 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 way to protect themselves. Chemicals (化学物质) are used by plants to live. 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, and the number of poisonous chemicals becomes more in the other leaves. “It’s like the injured (受伤的) leaves telling the others to fight against the enemy together, ” he said.
The tree also sends messages to plants near it by giving out a special smell. Golden Wattle trees in the nearly 45 meters will get the message and produce more poison in 10 minutes. Now, if an enemy eats too many of the trees’ leaves, he will die.
Every kind of plant is good at producing special chemicals. Animals that feed on plants or glass, like rabbits, can safely eat the leaves of one tree, but they may be hurt by its neighbor.
In this way, plants have not only developed their own way to protect themselves, but also shared it with others. So it’s impossible for a single animal to damage even a small area of forest.
