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 wolves.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.

Today I tried cooking a simply dish myself. I like eating fried tomatoes with eggs,and I thought it must to be easy to cook. My mom told me how to preparing. First I cut the tomatoes into pieces but put them aside. Next I broke the egg into a bowl and beat them quick with chopsticks. After that I poured oil into a pan and turned off the stove. I waited patiently unless the oil was hot. Then I put the tomatoes and the beaten eggs into pan together. "Not that way," my mom tried to stop us but failed. She is right. It didn't turn out as I had expected.发布:2024/11/18 20:0:1组卷:46引用:3难度:0.6948.I am now a good student in my class.But you don't know that when I(1)
