20.After years of heated debate,gray wolves were reintroduced to Yellowstone National Park.Fourteen wolves were caught in Canada and transported to the park.By last year,the Yellowstone wolf population had grown to more than 170 wolves.
    Gray wolves once were seen here and there in the Yellowstone area and much of the continental United States,but they were gradually displaced by human development.By the 1920s,wolves had practically disappeared from the Yellowstone area.They went farther north into the deep forests of Canada,where there were fewer humans around.
   The disappearance of the wolves had many unexpected results.Deer and elk populations-major food sources (来源) for the wolf-grew rapidly.These animals consumed large amounts of vegetation (植被),which reduced plant diversity in the park.In the absence of wolves,coyote populations also grew quickly.The coyotes killed a large percentage of the park's red foxes,and completely drove away the park's beavers.
   As early as 1966,biologists asked the government to consider reintroducing wolves to Yellowstone Park.They hoped that wolves would be able to control the elk and coyote problems.Many farmers opposed the plan because they feared that wolves would kill their farm animals or pets.
    The government spent nearly 30 years coming up with a plan to reintroduce the wolvers.The U.S.Fish and Wildlife Service carefully monitors and manages the wolf packs in Yellowstone.Today,the debate continues over how well the gray wolf is fitting in at Yellowstone.Elk,deer,and coyote populations are down,while beavers and red foxes have made a comeback.The Yellowstone wolf project has been a valuable experiment to help biologists decide whether to reintroduce wolves to other parts of the country as well.

17.Usually,when your teacher asks a question,there is only one correct answer.But there is one question that has millions of current answers.That question is"What's your name?"Everyone gives a different answer,but everyone is correct.
Have you ever wondered about people's names?Where do they come from?What do they mean?
People's first names,or given names,are chosen by their parents.Sometimes the name of a grandparent or other member of the family is used.Some parents choose the name of a well-known person.A boy could be named George Washington Smith; a girl could be named Helen Keller Jones.
Some people give their children names that mean good things.Clara means"bright"; Beatrice means"one who gives happiness"; Donald means"world ruler"; Leonard means"as brave as a lion".
The earliest last names,or surnames,were taken from place names.A family with the name Brook or Brooks probably lived near brook(小溪);Someone who was called Longstreet probably lived on a long,paved road.The Greenwood family lived in or near a leafy forest.
Other early surnames came from people's occupations.The most common occupational name is Smith,which means a person who makes things with iron or other metals.In the past,smiths were very important workers in every town and village.Some other occupational names are:Carter-a person who owned or drove a cart; Potter-a person who made pots and pans.
The ancestors of the Baker family probably baked bread for their neighbors in their native village.The Carpenter's great-great-great-grandfather probably built houses and furniture.
Sometimes people were known for the color of their hair or skin,or their size,or their special abilities.When there were two men who were named John in the same village,the John with the gray hair probably became John Gray.Or the John who was very tall could call himself John Tallman.John Fish was probably an excellent swimmer and John Lightfoot was probably a fast runner or a good dancer.
Some family names were made by adding something to the father's name.English-speaking people added-s or-son.The Johnsons are descendants of John; the Roberts family's ancestor was Robert.Irish and Scottish people added Mac or Mc or O.Perhaps all of the MacDonnells and the McDonnells and the O'Donnells are descendants of the same Donnell.
