Operation Migration
If you look up at the sky in the early fall in the northern part of North America,you may see groups of birds.These birds are flying south to places where they can find food and warmth for the winter.They are migrating（迁徙）.The young birds usually learn to migrate from their parents.They follow their parents south.In one unusual case,however,the young birds are following something very different.These birds are young whooping cranes,and they are following an airplane!
The whooping crane is the largest bird that is native to North America.These birds al-most disappeared in the 1800s.By 1941,there were only about 20 cranes alive.In the 1970s, people were worried that these creatures were in danger of disappearing completely.As a result,the United States indentified whooping cranes as an endangered species that they needed to protect.
Some researchers tried to help.They began to breed whooping cranes in special parks to increase the number of birds.This plan was successful.There were a lot of new baby birds.As the birds became older,the researchers wanted to return them to nature.However,there was a problem:These young birds did not know how to migrate.They needed human help.
In 2001,some people had a creative idea.They formed an organization called Operation Migration.This group decided to use very light airplanes,instead of birds,to lead the young whooping cranes on their first trip south.They painted each airplane to look like a whooping crane.Even the pilots wore special clothing to make them look like cranes.The cranes began to trust the airplanes,and the plan worked.
Today,planes still lead birds across approximately 1,200 miles(1,931 kilometers), from the United States-Canadian border to the Gulf of Mexico.They leave the birds at differ-ent sites.If a trip is successful,the birds can travel on their own in the future.Then,when these birds become parents,they will teach their young to migrate.The people of Operation Migration think this is the only way to maintain the whooping crane population.
Operation Migration works with several other organizations and government institutes.Together,they assist hundreds of cranes each year.However,some experts predict that soon,this won't be necessary.Thanks to Operation Migration and its partners,the crane population will continue to migrate.Hopefully,they won't need human help any more.

A.find warmth and food
B.raise baby whooping cranes

[填空题]
At picnics, ants are pests. But they have their uses. In industries such as mining, farming and forestry, they can help gauge the health of the environment by just crawling around and being antsy.
It has been recognized for decades that ants--which are highly sensitive to ecological change—can provide a near-percent barometer of the state of an ecosystem. Only certain species, for instance, will continue to thrive at a forest site that has been cleared of trees. (41) And still others will move in and take up residence.
By looking at which species populate a deforested area, scientists can determine how "stressed" the land is. (42) Ants are used simply because the>; are so common and comprise so many species.
Where mine sites are being restored, for example, some ant species will recolonize the stripped land more quickly than others. (43) Australian mining company Capricorn Coal Management has been successfully using an
