Golden lion tamarins (GLT) are among the most endangered animals on earth. They have fur which ranges in color from reddish orange to golden brown. They are the smallest monkeys in the world，and they weigh only half a kilogram. They move quickly through the forest. Each group of these delightful creatures needs a living space of about two square kilometres of thick forest. They are named after lions because of the ring of fur around their faces. Their only natural habitat(棲息地)is the Atlantic forest in Brazil.

Sadly，it is unusual to see a GLT nowadays，and there are very few of them left because they are hunted for the pet trade. In addition，the rapid expansion in the human population has resulted in the need for more land to grow crops，leaving them homeless.

GLTs live in close family groups. In the1970s，the Brazilian scientist，Eduardo Figueiro， realized what was happening to this rare animal，and began trying to save them，which has been supported by the government. He said，“It's so important to protect the animal，who evolved more than 20 million years ago. The worst problem is that the monkeys cannot travel without tree cover. It is trees that connect these groups. In this way，the monkeys can meet and socialize with each other. " Meanwhile , special patrols(巡邏) have been organized by government in the reserves to prevent hunting and forest fires.

As a result of these actions，the number of GLTs has grown to about 1500. There are also another 450 living in zoos throughout the world. Here they can be seen living in happy and close family groups，with the male gently taking much of the responsibility for the young.

A. main characteristics B. present situations

C. value D. habitat

2.According to Figueiro，to save GLTs the most important thing is to .

A. prevent forest fires B. keep as many trees as possible

3.What can be inferred from the text

A. GLTs are dying out nowadays.

B. Some GLTs feed on tree leaves.

C. Some GLTs are living in the Atlantic forest.

D. Brazil has been taking active actions to save GLTs.

4.We can conclude from the text that zoos
