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.Ziyuanku.com
Gray wolves once were seen here and there in the Yellowstone area and much of the continental United States, but they were gradually displacedby 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 fores 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.

During the school year many parents take on the role of driver as they drive their children from one lesson to another .Understandably so. Many of us want our children to have a little taste of everything, from organized sports to music, dance and more. But we can overdo it, leaving our children feeling a little burnt out, and according to parent educator Diane Loisie ,it’s their school work which suffers the most. “After school, if they’re busy in a number of sporting events, besides they need to do their homework, then the time they’ll feel sleepy is in the classroom. Your child needs free time. So if you’re filling up that after school time, then it’s during the day that they’re going to be taking a break.”
Professor Claire McDermott agrees that there’s a lot to be gained from sometimes putting those scheduled lessons and activities away. “Relaxing time is important for children. It’s time just to do the things they want to do. A child can go up to their room, or they can play around. It doesn’t look like productive time; parents certainly wouldn’t be saying ‘Wow, are they ever learning things now?’ But this relaxing time gives both the body and the brain just a wonderful chance to relax after a day. It helps a child prepare for sleep, but it also helps to understand the learning that’s gone on that day.”
It’s hard to prevent signing our kids up for some activities and lessons. After all, many of us want our children to have a head start in life and the chance to join in great activities in the arts or sports is a part of that. However, Loisie feels that in the long run most children feel better with just a few key activities because it gives them an opportunity to master them. “When we get our children in too many activities because we want our children to experience everything, then what we’re doing is setting them up not to be good at one thing or gaining a skill.” So choose your children’s activities wisely. It may be one of the best things you’ve ever done for your kids… and for the family drivers!What is the biggest disadvantage for children to attend too many lessons after school?
| A．They can get bored easily about everything. |
| B．They might have no time to do the homework. |
| C．They might not pay much attention to learning. |
| D．They cannot easily focus on learning during the day. |
What should we think of children’s playing around aimlessly?
| A．It is productive. | B．It is helpful. | C．It is a bad habit. | D．It is a waste of time. |
Why should parents limit the activities our children attend?
| A．Because children have no time. |
| B．Because children cannot learn many things. |
| C．Because children do not have enough sleep. |
| D．Because children cannot focus on too many activities. |
What is the main idea of this passage?
| A．Don’t be children’s drivers after school. |
| B．Choose activities for your children wisely. |
| C．Make your children learn as much as possible. |
| D．Let children learn something from various subjects. |
There are two kinds of people in the world. Those of the first kind are born idlers (游手好闲者), taking interest in nothing. It seems what they live for is to pass time idly. They simply don’t know why they have to do so, nor will they bother to ask. The other kind are those who take things seriously and never wish to idle away their life. But only a part of the second group are eager enough to make success. All the others fail to make enough effort to make their dreams come true.
Why do things so happen to them? What are the reasons?
I later find out that some people are determined. They are “igniters” that catch fire of their own, giving light and heat. But that’s not the case with others. They may be fuels but not igniters. As pieces of wood or coal, they need a match or a lighter to make them burn so that their energy can be released to give off light and heat.
The majority of people need some igniter to light them. Thus igniter becomes a must for those people to succeed. Unless a suitable igniter comes their way, they will always remain idle like cold unused firewood or coal.
Fortunately, such an igniter is not difficult to meet. One may find it in an instructive book, a film story, a few words of a close friend, some advice of a good teacher, a pleasant journey, or an unexpected love.
Any of these, coming at the right time, can serve as an igniter to start one’s enthusiasm for learning or for a better career, to turn him from a passive state of waiting to an active state of pursuing, to lend him strength to go ahead bravely. In that case, what he has prepared for years will be quickly turned into fruitful reality.
Such an igniter may turn up of itself, but most likely we have to find it ourselves. Never let a chance slide away, for it is the key to your success. According to the text, “________” are the persons that can light many people so that their energy can be released to give off light and heat.
| A．idlers | B．igniters | C．fuels | D．serious people |
According to the writer, what do most people definitely need to succeed?
| A．Storing a lot of energy. |
| B．Great interest in everything. |
| C．An igniter coming at the right time. |
| D．Wonderful dreams about a bright future. |
The writer writes the article to _________.
| A．describe two kinds of people |
| B．encourage people to find chances to succeed |
| C．praise those who work hard |
| D．make fun of idlers |
For many years, I was convinced that my suffering was due to my size. I believed that when the weight disappeared, it would take old wounds, hurts and rejections with it.
Many weight-conscious people also mistakenly believe that changing our bodies will fix everything. Perhaps our worst mistake is believing that being thin equals being loved, being special, and being cherished. We fantasize about what it will be like when we reach the long-awaited goal. We work very hard to realize this dream. Then, at last, we find ourselves there.
But we often gain back what we have lost. Even so, we continue to believe that next time it will be different. Next time, we will keep it off. Next time, being thin will finally fulfill its promise of everlasting happiness, self-worth, and, of course, love.
It took me a long while to realize that there was something more for me to learn about beauty. Beauty standards vary with culture. In Samoa a woman is not considered attractive unless she weighs more than 200 pounds. More importantly, if it’s happiness that we want, why not put our energy there rather than on the size of our body? Why not look inside? Many of us strive hard to change our body, but in vain. We have to find a way to live comfortably inside our body and make friends with and cherish ourselves. When we change our attitudes toward ourselves, the whole world changes.What does the underlined word “everything” in Paragraph 2 mean?
| A．All the problems. | B．All the properties. |
| C．The whole world. | D．The absolute truth. |
What can be inferred about the author?
| A．The author is a Samoan. |
| B．The author succeeded losing weight. |

According to the text, those who have lost weight first and gained it back later feel _______.
| A．angry about the regained weight |
| B．indifferent to the regained weight |
| C．optimistic about future plans on weight control |
| D．they should give up their future plans on weight control |
The text tries to stress the importance of ____________.
| A．body size | B．attitudes toward life |

How to protect children Web fans from unsuitable material on-line while encouraging them to use the Internet has long been discussed in the U.S.
For some parents, the Internet can seem like a jungle, filled with danger for their children. But jungles contain wonders as well as dangers and with good guides, some education, and a few precautions(预防措施), the wilds of the Internet can be safely navigated(航行). “Kids have to be on-line. If we tell our kids they can’t have access(机会) to the Internet, we’re cutting them off from their future,” said an expert.
Most kids have started to use search engines. Many of them are great for finding tons of interesting Internet sites, and they can also locate places where you might not want your kids to go. There are search engines designed just for kids. A certain software contains only sites that have been selected as safe. The most popular way to limit access would be to use what is known as a “content screener(过滤器)”. But this can’t be wholly reliable(可靠), and the best thing parents can do is to talk to their kids and let them know what is OK or not OK to see or do on the Internet. Another way is that mum or dad is nearby when the child is surfing(浏览) the Internet.
A few other tips●Don’t put the PC in a child’s room but keep it in an area where mum or dad can keep an eye on things. That also makes the Internet more of a family activity.
●Ask your child what he or she has been doing and about any friends they make on-line.
●Tell your child not to give on-line strangers personal information, especially like address and phone number.
●And tell your children never to talk to anyone they meet on-line over the phone, send them anything, accept anything from them or agree to meet with them unless you go along.The passage is mainly about the subject of _______.

I came to live here where I am now between Wounded Knee Greek and Grass Greek. Others came too, and we made these little grey houses of logs that you see, and they are square, It is a bad way to live, for there can be no power in a square.
You have noticed that everything an Indian does is in a circle, and that is because the Power of the World always works in circles, and everything tries to be round. In the old days when we were a strong and happy people, all our power came to us from the respectful circle of the nation, and so long as the circle was unbroken, the people were getting rich. The flowering tree was the living center of the circle, and the circle of the four quarters nursed it. The east gave peace and light, the south gave warmth, the west gave rain, and the north with its cold and strong wind gave strength and continuous power. This knowledge came to us from the outer world with our brief. Everything the Power of the World does is done in a circle. The sky is round, and I have heard that the earth is round like a ball, and so are all the stars. Birds make their nests in circle, for theirs are the same as ours. The sun comes forth and goes down again in a circle. The moon does the same, and both are round. Even the seasons form a great circle in their changing, and always come back again to where they were. The life of a man is a circle from childhood to childhood, and so it is in everything where power moves. Our places were like the nests of birds, and these were always set in a circle, the nation’s circle, a nest of many nests, where the Great Spirit meant for us to nurse our children.
But the Wasichus (Indian word for “white people”) have put us in these square boxes. Our power is gone and we are dying, for the power is not in us any more. You can look at our boys and see how it is with us. Where we were living by the power of the circle in the way we should, boys were men at twelve or thirteen years of age. But now it takes them very much longer to be full - grown.According to the passage, the Indians _______.
