Part II提高部分
一、阅读理解
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 vegelation(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 National 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.
1.What is the text mainly about
A.Wildlife research in the United States.
B.Plant diversity in the Yellowstone area.
C.The conflict between farmers and gray wolves.
D.The reintroduction of wolves to Yellowstone National Park.
2.What does the underlined word "displaced" in paragraph 2 mean
A.Tested. B.Separated. C.Forced out. D.Tracked down.
3.What did the disappearance of gray wolves bring about
A.Damage to local ecology. B.A decline in the park's income.
C.Preservation of vegetation. D.An increase in the variety of animals.
4.What is the author's attitude towards the Yellowstone wolf project
A.Doubtful. B.Positive. C.Disapproving. D.Uncaring.

I fell in love with Yosemite National Park the first time I saw it. My parents took us there for camping.

That has been my life's passion(热爱) ever since— 3 the rocks and mountains of Yosemite. I've long made Yosemite my 4 .
About 15 years ago I started seeing a lot of 5 , like beer cans, empty boxes, around the area. It's beyond me why visitors started respecting the place 6 and treated such a beautiful home-like place this way.

五、读后续写
阅读下面材料,根据其内容和所给段落开头语续写两段,使之构成一篇完整的短文。
After filling out fifty applications, going through four interviews, and winning one offer, I found what I could get—a teaching job at what I considered a distant wild area: western New Jersey. My characteristic optimism was alive only when I reminded myself that I would be doing what I had wanted to do since I was fourteen—teaching English.
School started, I was teaching English. I worked hard, taking time off only to eat and sleep. And then there was my sixth-grade class—seventeen boys and five girls who were only six years younger than me. I had a problem long before I knew it. I was struggling in my work as a young idealistic teacher. I wanted to make literature come alive and to promote a love for the written word. The students wanted to throw spitballs and whisper dirty words in the back of the room.
In college I had been taught that a successful educator should ignore bad behavior. So I did, confident that, as the textbook had said, the bad behavior would disappear as I gave my students positive attention. It sounds reasonable, but the text evidently ignored the fact that humans, particularly teenagers, rarely seem reasonable. By the time my boss, who was also my task master known to be the strictest, most demanding, most quick to fire inexperienced teachers, came into the classroom to observe me, the students exhibited very little good behavior to praise.
My boss sat in the back of the room. The boys in the class were making animal noises, hitting each other while the girls filed their nails or read magazines. I just pretended it all wasn't happening, and went on lecturing and tried to ask some inspiring questions. My boss, sitting in the back of the room, seemed to be growing bigger and bigger. After twenty minutes he left, silently. Visions of unemployment marched before my eyes. I felt mildly victorious that I got through the rest of class without crying, but at my next free period I had to face him.

五、答案：
Paragraph 1:
After class, I walked to his office, took a deep breath, and opened the door. My boss gazed at me long and hard. Anxious and ashamed, I said nothing, wondering if he would fire me. He handed me an envelope, and I opened it, reading. It was not an unemployment letter but a letter with several suggestions about my teaching, one of them in red: An educator should respect students' feelings. Almost immediately, a warm glow of emotion rose inside me, so I made up my mind to change my attitude.
Paragraph 2:
Inspired by his advice, I walked towards the classroom, determined to make a change. As the bell rang, I stood on the platform and announced, "Boys and girls, let's begin with your voice about my literature lesson." Suddenly, a complete silence fell. Each lifted his/her head and cast me a puzzled look. Flashing them a smile, I encouraged, "You can say anything you'd like to say!” At this moment, the students soon amazingly came to life thanks to their brilliant voices, bringing me to what my strictest boss enlightened me about: Respecting the students instead of ignoring them will make a difference.
