Camels mainly eat grass, leaves and bushes. They can walk for more than 600 kilometers even if they are not given water. 7 But when there is water, they can drink as much as 90 liters. Camels walk slowly. They don’t like running because it’s too hot. But if they need, they can run at 20 kilometers an hour.

From a seed (種子) that is smaller than a pea grows the tallest of trees. The coast redwood is the largest giant among North America’s trees.
redwoods
Redwoods are most special for two reasons. The first is their size. Imagine standing next to a tree that is the height of a 30-story building. The second is their age. Redwoods commonly make it to 600 years or so. It has been found that some trees are more than 2000 years old.
To find a coast redwood, you have to go to Oregon or California. A coastline about 450 miles long and up to 35 miles wide is home to the redwoods. Coast redwoods don’t grow anywhere else in the world, because the coast of the Pacific Ocean provides a special environment for the redwoods. Cool, moist (濕潤(rùn)的) air comes off the ocean and keeps the trees moist all year round, which is important because almost all of the area’s rain falls between October and May. During the dry summer months, the trees depend on moisture from the thick fog that often hangs over the coast.
Redwoods have their own protection systems. Most of redwoods’ branches and leaves are high up on the tree. This keeps them safe from forest fires. Also, the bark (樹(shù)皮) of a redwood is as much as 12 inches thick. The thick covering protects the lower part of the tree from fire damage. Besides, redwoods are safe from insect damage (蟲(chóng)害) because the wood contains a bitter-tasting (苦味的) chemical called tannin.
If you ever get a chance, visit a redwood forest, and imagine who might camp there a thousand years ago. Look upward and just imagine how high the trees might grow if we protect them.
