Birds are the only animals that have feathers. Feathers are the coat a bird wears on its body，just like the hair most of other kinds of animals wear on their bodies. We，human beings，don't depend on feathers or hair to keep us warm，as birds and animals do，we have our clothes. The feathers and shapes of the birds help us to tell one kind from another. Feathers come in beautiful colors.

Many birds use colors to hide from enemies（敌人）. This is called camouflage. All birds molt（换毛），but the ptarmigan molts twice a year，changing color to go right for the season. In winter，when snow is on the ground，it has white feathers. In spring，it molts and grows brown feathers that match up with the land，grass，trees or other conditions where it lives. When winter comes，it molts again and grows white feathers.

Besides feathers，birds can have good voices and are good at singing. Many birds，such as the robin，sing to send messages to other birds. Each type of songbird has its own song. By singing，birds show who they are and where their land is. In spring，many birds sing together loudly at daybreak. The sound they make is known as the dawn chorus，so﹣called"early morning singing of love" by many people in a Chinese yet simpler way.

They need to understand what is going on with their bodies, how to do with those changes and learn to take responsibility (责任).

A young person may begin puberty at 8, while another may not start puberty until 14 to 15. Usually, girls start puberty before boys do. For both girls and boys, it is usually complete by the age of 18.

During these years, the body develops in many ways. Feeling will also change quickly. Young boys at this stage are interested in having fun and being accepted by others. They need to think before they act and make up their minds for themselves.

3. 阅读下面的短文，根据短文内容回答问题。

Glaciers(冰川) are large bodies of ice and snow. Because they're so icy, it's very hard for things to live on them. But glacier mice do somehow.

Of course, glacier mice aren't mice. They're round balls of moss(苔藓) that can grow to about the size of a tennis ball. They're usually found in groups near small rocks on the surface of icy glaciers.

Normal moss can't form on a glacier, so scientists believe glacier mice probably form around something small, like a bit of dust(尘土). Because staying on the ice too long would kill the moss, glacier mice form into a ball. It allows them to move around, so that their different parts touch the ice at different times.

Some scientists once did an experiment on glacier mice. They put a small device( 装置 ) inside 30 glacier mice to follow their movements. They learned that the mice traveled about 2.5 centimeters(厘米) a day. They seemed to move in groups. They moved in the same direction and at about the same speed, almost like a group of animals. The scientists tested several ideas that might explain how the mice moved together, such as rolling downhill, being blown by the wind, or following the sun. None of these could explain the movement of the glacier mice.

Glacier mice are still a mystery to scientists. For their next experiment, the scientists said they would use cameras to take pictures of the movements of the mice over a long period of time. Are you looking forward to getting the answer?

(1) Are glacier mice a kind of animal or plant?

(2) How do the glacier mice fight against the cold ice?

(3) Where did the scientists put the small device?

(4) How far can the glacier mice move in a week?

(5) What do you think of the glacier mice?
