1 . 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.

2 . Your house may have an effect on your figure. Experts say the way you design your home could play a role in whether you pack on the pounds or keep them off. You can make your environment work for you instead of against you. Here are some ways to turn your home into part of your diet plan.

Open the curtains and turn up the lights. Dark environments are more likely to encourage overeating, for people are often less self­conscious (难为情) when they’re in poorly lit places—and so more likely to eat lots of food. If your home doesn’t have enough window light, get more lamps and flood the place with brightness.

Mind the colors. Research suggests warm colors fuel our appetites. In one study, people who ate meals in a blue room consumed 33 percent less than those in a yellow or red room. Warm colors like yellow make food appear more appetizing, while cold colors make us feel less hungry. So when it’s time to repaint, go blue.

Don’t forget the clock—or the radio. People who eat slowly tend to consume about 70 fewer calories (卡路里) per meal than those who rush through their meals. Begin keeping track of the time, and try to make dinner last at least 30 minutes. And while you’re at it, actually sit down to eat. If you need some help slowing down, turn on relaxing music. It makes you less likely to rush through a meal.

Downsize the dishes. Big serving bowls and plates can easily make us fat. We eat about 22 percent more when using a 12­inch plate instead of a 10­inch plate. When we choose a large spoon over a smaller one, total intake (摄入) jumps by 14 percent. And we’ll pour about 30 percent more liquid into a short, wide glass than a tall, skinny glass.

3 . As our Earth’s temperature warms up because of climate change, it is having unexpected effects on our world’s forests. When temperatures rise, trees close their skins to ___________ the loss of water, and this, in turn, slows down the ___________ of photosynthesis(光合作用). As a result, these trees are shorter and grow slowly, as well as have a ___________ death rate.

Climate change also increases the ___________ of droughts and wildfires. After wildfires, it takes a while for the forest systems to ___________ , and in some cases, the forests are ___________ permanently. Trees that are stressed are also ___________ to attacks by bacteria(细菌). In tropical forests, vines that use the trees as ___________ can often choke the trees and rob them of nutrients. Finally, humans have ___________ the forest landscape through logging. When trees are replanted on the soil, they will never grow as large as the ____________ trees that were cut down.

As these forests disappear, species that once called them “home” are forced to change, ____________ the variety of those systems. ____________ , some endangered species are unable to ____________ and die. Old-growth forests are disappearing in all regions of our world. When forests die, younger forests that are reestablished in the same area grow back weaker and smaller ____________ poor vegetation. With trees dying increasingly and continuously, will future generations ____________ out on the wonders of forests?

4 . Where do you go when you want to learn something？

School？ A friend？ A tutor？These are all _________ places of learning. But it may well be that the learning you really want _________ somewhere else instead. I had the _________ of seeing this first hand on a _________．

My daughter plays on a recreational soccer team. They did very well this season and so _________ a tournament, which normally was only for more skilled club teams. This led to some _________ experiences on Saturday as they played against teams _________ trained. Through the first two games, her _________ did not get one serious shot on goal. As a parent, I _________ seeing my daughter playing her best，____________ still defeated.

It seemed that something clicked with the ____________ between Saturday and Sunday. When they ____________ for their Sunday game, they were ____________ different. They had begun to integrate (融合) the kinds of play and teamwork they had ____________ the day before into their ____________．They played aggressively and ____________ scored a goal.

10 . Travelling can be a fun way to gain life experience, but what if you’re a student and don’t have enough money for a trip? Don’t worry. Here are some useful tips.

Save: This probably is the most important preparation for travelling. Cut expenses (花费) to fatten your wallet so you’ll have more choices about where to go and how to get there.

Plan ahead: Don’t wait until the last minute to plan your trip. Giving yourself several months to get ready can mean security and savings.

Do your homework: No matter where you go, research the places you will visit. Decide what to see. Travel books will provide information on the cheapest hotels and restaurants.

Plan sensibly: Write down how much you expect to spend on food and hotels. Stick to (坚持) your plan, or you may not have enough money to cover everything.

Travel in groups: Find someone who is interested in visiting the same places. By travelling with others you can share costs and experiences.

Work as you go: Need more money to support your trip? Look for work in the places you visit.

Go off the beaten path: Tourist cities may be expensive. You may want to rethink about your trip and go to a less known area. Smaller towns can have many interesting activities (活动) and sights.

Pack necessary things: The most important things to take are not always clothes. Remember to take along medicine in case you get sick and snacks in case you cannot find a cheap restaurant.

By planning sensibly, even students can enjoy their travel. Your travel experiences will be remembered for a lifetime.
