解放军文职招聘考试A Wolf in Danger

 What is happening to the timber wolf today?

Native Americans and early settlers often went to sleep to the sound of a lonely lullaby(催眠曲). It was the song of the wolf howling in a distant forest. There were many wolves then. One kind was the North American timber wolf.

Wolves are important to the balance of nature because they eat sick and weak animals. In Colorado, people tried to help deer by shooting wolves. But then there were so many deer that many of them starved to death.

The timber wolf is on the endangered special list. Animals on this list are in danger of disappearing from the earth. People drove the wolves away by cutting down the forests to build houses, towns, and highways. Timber wolves are now found only in Canada, Alaska, Michigan, and Minnesota.
