Trees are useful to man in three important ways: they give him wood and other useful things, they give him cool places, and they help to stop drought and flood.

Unluckily, in many parts of the world, man has not found that the third of these points is the most important. Man wants to make money from trees, so he has cut them down in large numbers, only to find that without them he has lost the best friends he had. And also, he is usually too careless to plant and look after new trees. So the forests slowly disappear.

This does not only mean that man will have fewer trees. The results are even worse: for where there are trees, their roots break up soil-make the rain in-and also bind the soil, thus stopping it from being washed away easily; but where there are no trees, the rain falls on hard ground and flows away, causing floods and carrying away the rich top-soil. When all the top-soil is gone, nothing is left but useless desert.

Have you ever beard of Iceland? Iceland is a country, one-tenth of which is covered with ice. However, it is said that Iceland is the land of heat. Smoking volcanoes (火山), white steam (蒸汽) and hot springs are more amazing than the other sights including ice there.
It has taken millions of years for volcanoes and lava flows (熔岩流) to build Iceland. When hiking through one of Iceland’s many ancient lava fields, you may notice something strange. White steam is rising from each vent in front of you. Iceland is covered with vents which steam can pass out of. The steam comes from naturally heated rocks and hot water below the Earth’s surface (表面).
Like steam vents, hot springs can be seen here and there in the ancient lava fields. Blue Lake is the most famous hot spring in Iceland. It isn’t far from the capital city of the country. The water and white earth in it can make your skin as soft as a newborn baby’s skin. Enjoy that water, because it has traveled a long way. It starts nearly two kilometers under Blue Lake. There, water from the ocean continues moving up slowly into the spaces between hot rocks below the surface. And then the water is heated by hot rocks. Powerful machines and long pipes (水管) help bring the heated water to the surface. People in Iceland use natural hot water for hot springs. Besides, they use it to create electricity that can be used to heat homes and even greenhouses.
Iceland is one of the few places on the Earth where active volcanoes lie below ice. Heat from the volcanoes creates a strange and wild beauty. Therefore, some people believe that it’s better to call the country “Heatland” instead of Iceland. If you have a chance to travel there, take it.

The elephant is the largest animal to walk on Earth. An elephant can carry a load of 1,200 pounds（磅）. They eat 300 pounds of food a day. An elephant baby can weigh 200 pounds at birth. Elephants can live up to 70 years.
Elephants can be trained to carry logs with their trunks（象鼻）, and have been used in the forestry industry in Asia for many years.
Elephants use their ears as a cooling system. Blood  flows through veins (静脉) in the ears and as the elephant flaps (拍击) his ears, the blood cools and flows through his body to cool off other parts.
There are two kinds of elephants: the African elephant and the Indian elephant. African elephants can be identified(识别) by the larger ears. The African elephant grows up to 10 feet tall and weighs as much as 12,000 pounds.
The Indian elephant grows up to 9 feet tall, and weighs up to 8,000 pounds. It’s easy to identify because of its smaller ears. Most circus (马戏团) elephants are Indian elephants. Another name for the Indian elephant is the Asian elephant.
