1 . Yosemite is a national park in California. It is very beautiful and big. The park includes more than 760,000 acres in the California Mountains. Most of the park is wilderness.
The part of Yosemite that everyone likes is Yosemite Valley. It is a tiny valley that is 7 miles long and less than 1 mile wide. It has tall rock walls and streams that splash down in waterfalls. More than two million visitors come to the valley each year.
One ranger (守护人) says the number of visitors is more than the land can handle. The valley has 4,500 camping spots. It has a hotel that can hold 4, 000 families. This is still not enough to handle all of the visitors. The valley has grown so big that it has a lot of traffic and crime.
A worker says the park is trying to keep the beauty of the park and let everyone visit. Some areas have been fenced off from people and planted with seeds to try to keep them beautiful.
A former worker thinks Yosemite should get more money to take better care of the park. He would also like to teach people what the park service is trying to do.
Some people are trying to save Yosemite Valley. A plan has been made to get rid of some buildings. There will be fewer cars allowed inside the park. More buses will help get people around.

2 . As wildfires continued to sweep across Australia, the loss of life in the area was reaching astonishing numbers. Ecologists (生态学家) at the University of Sydney said that nearly half a billion animals and plants had been wiped out since the fires began several months before. Images and videos from the area showed kangaroos trying to escape from burning forests and charred (烧焦的) bodies of koalas lying on the ground.
Koalas had been already under threat because of significant habitat loss, and they were hit particularly hard compared with other animals. Ecologists said nearly 8,000 koalas—about one-third of the population in their primary habitat—were believed to have died from the big fires. Professor Dieter Hochuli from the University of Sydney said it wasn’t just the well-known species, such as kangaroos, koalas and emus (鸸鹋), that were in danger. Insects also suffered losses. Additionally, many rare plant species might have disappeared completely.
While animal hospitals were taking in as many animals as possible to treat burns and nursed them back to health, services had overall struggled to keep up with the amount of care needed. And the animals that had survived would have trouble finding food and shelters in the ongoing fire, so they were still in a dangerous situation.
“We’re getting a lot of lessons out of this and it’s just showing how unprepared we are,” Dr. Sussan Ley said. “Now Australia is burning and national parks and our native animals are being destroyed. People have lost homes. People have died. Firefighters have been killed defending communities, most recently last night. There’s no plan in place even wildlife carers don’t have plan for when they can go in after fire.
1. What’s the purpose of the second paragraph?| A．To explain why there were so many rare animals in Australia. |
| B．To show the terrible effect Australian wildfires had on species. |
| C．To further confirm Professor Dieter Hochuli’s unique opinion. |
| D．To warn people to take good care of wild animals and plants. |
| A．They failed to recover from serious burns. | B．They might be hunted by people for food. |
| C．They were short of food and shelters. | D．They were unable to get nursing services. |
| A．Many rare animal species might have disappeared. |
| B．Measures should be taken to prevent Australian wildfires. |
| C．Australian wildfires killed nearly half a billion animals and plants. |
| D．Ecologists have made great efforts to find the causes of wildfires. |
3 . It is the year 3000. I come to a place where I can’t see any water, plants or animals but black clouds in the sky and sand everywhere. It’s very dry so I drink some water that I carry with me. A native sees what I do and asks “What is it?” I pour some water and tell him it’s called water. “Oh, I’m so lucky that I can see water!” the man shouts in an excited voice. “You have never seen water? But how can you live without water?” I ask.
“Harry, get up, it is 7 o'clock, or you will be late!” a voice comes to my ears. “Oh! What a strange dream I dreamed just now!”
In class, I always think of that dream. And I also think of the fresh air, clean water, blue sky, green plants and animals in our world nowadays. How beautiful our life is!
But in order to make more money, people have built more and more factories. These factories send out waste smoke and water with chemicals which are harmful to the environment. The pollution is becoming worse and worse, and as a result, some animals and plants die out. With the development of agriculture, farmers spray aerosol (喷雾) and fertilizer, which also pollute the water and air. In the street the cars and buses are sending out heavy smoke which pollutes the air badly. Even tourism is harmful to the environment. When some tourists travel somewhere, they throw the plastic bags and rubbish onto the ground.
These behaviors are polluting the environment and the environment will become the greatest problem of the world. We shouldn’t pollute the environment any more. Otherwise more and more animals and plants will disappear. And maybe my dream will come true in the future.

Yesterday I was walking around the park while I saw some rubbishes left on the ground. People just walk by as if they had not seen it. I thought I would do something differently. I picked up and put it into a nearby dustbin. I was felt nice because I saw someone else doing a same thing as I had just done. I thought my kindness had affected him. Saving the Earth is save us humans. It is a good lesson what we should learn in life and together we can make the Earth a good place to live one step at a time.
5 . California has lost half its big trees since the 1930s, according to a study to be published Tuesday and climate change seems to be a major factor（因素）.
The number of trees larger than two feet across has declined by 50 percent on more than 46, 000 square miles of California forests, the new study finds. No area was spared or unaffected, from the foggy northern coast to the Sierra Nevada Mountains to the San Gabriels above Los Angeles. In the Sierra high country, the number of big trees has fallen by more than 55 percent; in parts of southern California the decline was nearly 75 percent.
Many factors contributed to the decline, said Patrick Mclntyre, an ecologist who was the lead author of the study. Woodcutters targeted big trees. Housing development pushed into the woods. Aggressive wildfire control has left California forests crowded with small trees that compete with big trees for resources（资源）.
But in comparing a study of California forests done in the 1920s and 1930s with another one between 2001 and 2010, Mclntyre and his colleagues documented a widespread death of big trees that was evident even in wildlands protected from woodcutting or development.
The loss of big trees was greatest in areas where trees had suffered the greatest water shortage. The researchers figured out water stress with a computer model that calculated how much water trees were getting in comparison with how much they needed, taking into account such things as rainfall, air temperature, dampness of soil, and the timing of snowmelt（融雪）.
Since the 1930s, Mclntyre said, the biggest factors driving up water stress in the state have been rising temperatures, which cause trees to lose more water to the air, and earlier snowmelt, which reduces the water supply available to trees during the dry season.

| B．The increasing variety of California big trees. |
| C．The distribution of big trees in California forests. |
| D．The influence of farming on big trees in California. |
| A．Ecological studies of forests. | B．Banning woodcutting. |
| C．Limiting housing development. | D．Fire control measures. |
| A．Not enough snowmelt. | B．A longer dry season. |

6 . Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your choice of sport might have great influence on the environment.
Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses(高尔夫球场) in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortages in some local areas.
In fact, there are many environment friendly sports. Power walking is one of them that you could take up today. You don't need any special equipment except a pair of good shoes; and you don't have to worry about resources and your purse. Simple and free, power walking can also keep you fit. If you walk can regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and control your weight better.
Whatever sport you take up, you can make it greener by using environment friendly equipment and buying products made from recycled materials. But the final goal should be "green gyms". They are better replacements(代替物) for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all, it's free.

7 . The early life of the green sea turtle (海龟) is full of danger. Only one in 1,000 baby sea turtles survive to adulthood (成年). From its home in the sand, it breaks its egg with an egg tooth. Its mother is not there to help it. Instead, it is greeted by crabs, coyotes, and dogs waiting to eat it for dinner. To survive, the baby turtle must hide in the sand until night. Then, it moves slowly to the sea.
The small turtle must swim hard to reach the ocean waters. In the sea, it tries hard to find food. It must also keep itself from being food for fish.
As dangerous as the sea turtle’s life is in the natural world, its most dangerous enemies are humans. The rubbish left by humans in the ocean causes problems for the small green sea turtle. A little turtle might eat a piece of plastic (塑料) in the sea. It might also eat oil on the ocean’s surface. Young turtles also get caught in fishing nets. There are laws against hunting sea turtles. Still, many are hunted, both for their meat and for their shells (壳). All of these dangers must be prevented.
Sea turtles that do survive to grow into adulthood go through many changes. For example, adult green sea turtles weigh about 500 pounds. They stop eating jellyfish and other meat and eat only plants. And they may plan a trip to go back home again. A mother sea turtle goes back to the beach where she was born. This is the only place where she will lay eggs. Even if it has been forty years since she was a baby, she always knows her way back home.

8 . Your next car might drive itself. After years of trials on city streets, driverless vehicles are now nearing the production phase. Last month, a driverless bus began carrying passengers through Lyon, France. Most in the automobile industry think self-driving vehicles will be on the road by 2020 or before.
Driverless cars will at first be huddled with human-driven cars. But the first places where they will become dominant（占支配地位的）are dense urban areas-precisely the spots most damaged by the automobile age. Many advanced cities are already reducing the role of human-driven cars. Driverless cars will quicken that process and will bring us great benefits.
Driverless cars will reduce accidents by around 90 percent. That's big-the annual death toll on the world's roads is about 1.2 million a year. Pollution and carbon emissions will drop, because urban driverless cars will be electric. The old, otherwise they would stay at home most of the time and the disabled and teenagers will suddenly gain mobility.
On the other hand, driverless cars will bring catastrophe（灾难）.The best thing about the automobile age is that it employs tens of millions of people to make, market, insure and drive vehicles. Over the next 20 years, most men who now drive trucks, taxis and buses will see their jobs reduced. Carmakers are especially scared. A few cars in the future might be made by tech companies such as Apple, Baidu and Google. Imaging the impact on Germany, where the automotive sector is the largest industry.
Dramatic change is coming, and driverless cars could arrive by 2020. But governments have hardly begun thinking about it. Only 6 percent of the biggest US cities have factored them into their long-term planning.
A decade ago anyone hardly saw the smartphone coming. It has brought an epidemic of mass addiction. Let's hope we do a better job of handling the driverless car.
1. The underlined words "be huddled with "in Paragraph 2 can be replaced by "________".| A．show up with | B．exist together with |

| B．They will only be used in urban areas. |
| C．They will not cause any road accident. |
| D．They aren't still seriously taken by governments. |
| A．Doubtful. | B．Negative. |
| C．Objective. | D．Worried. |
9 . As most people know, in the last few years, sandstorms have swept across many cities and areas of North China, polluting the air and disturbing daily lives of human beings. People look dirty and suffer many kinds of illnesses, such as breath difficulty. The sandstorm is such a serious problem that it has not only weakened the industrial and agricultural development of our country but also caused a lot of trouble to the living conditions of the Chinese people.
Therefore, effective measures should be taken as soon as possible to stop its happening. So how should we deal with the frightening sandstorms?
Some experts offer practical advice as follows: For one thing, more money ought to be put into tree planting and forest protection in order to keep more water on the Earth. For another, government of all countries should make laws on environment protection. For example, banning the use of throw-away chopsticks and punishing illegal tree cutting. Scientists should also study and find ways to lower the grade of its destruction and to improve the environment. As for some schools, education about sandstorms should be spread properly and timely to make more and more people attach great importance to this problem.
How people look forward to sunny days with soft wind touching their faces now and forever! The golden days can come back so long as we try our best to protect the natural environment from today on. And the fact is that what I expect is not just a dream. There are some sweet fruits from the early efforts.
