1 . Eradajere Oleita thinks she may have a partial solution to two of our country’s persistent problems: garbage and poverty. It’s called the Chip Bag Project. The 26-year-old student and environmentalist from Detroit is asking a favor of local snack lovers: Rather than toss your empty chip bags into the trash, donate them so she can turn them into sleeping bags for the homeless.
Chip caters drop off their empty bags from Doritos, Lay’s, and other favorites at two locations in Detroit: a print shop and a clothing store, where Oleita and her volunteer helpers collect them. After they sanitize (消毒) the chip bags in soapy hot water, they slice them open, lay them flat, and iron them together. They use padding and liners from old coats to line the insides.
It takes about four hours to sew a sleeping bag, and each takes around 150 to 300 chip bags, depending on whether they’re single-serve or family size. The result is a sleeping bag that is “waterproof, lightweight, and easy to carry around,” Oleita told the Detroit News. Since its start in 2020, the Chip Bag Project has collected more than 800,000 chip bags and, as of last December, created 110 sleeping bags.
Sure, it would be simpler to raise the money to buy new sleeping bags. But that’s only half the goal for Oleita — whose family moved to the United States from Nigeria a decade ago with the hope of attaining a better life — and her fellow volunteers. “We are devoted to making an impact not only socially, but environmentally,” she said.
And, of course, there’s the symbolism of recycling bags that would otherwise land in the trash and using them to help the homeless. It’s a powerful reminder that environmental injustice and poverty often go hand in hand. As Oleita said, “I think it’s time to show connections between all of these issues.”

2 . The monarch butterfly migration(迁徙)is at risk because of climate change and other envuronmental factors.
Do you know that monarch butterflies can travel up to 50- 100 miles a day? If you know they need travel about two months, you’ll have an idea of the distance monarchs travel to get to Mexico.
Monarch butterflies are the only hind of butterflies to make a two-way migration. They travel to Mexico to escape the winter season in the northern climates. Cold, wet weather is considered deadly for monarchs, while hotter, diner summer change their homes in the north.
2020, however, saw a 26% drop from the year earlier in migration patterns reported in a report from the World Wildlife Fund and the Mexican government. With this drop, the butterflies’ population covered only 2.1 hectares in 2020, compared to 2.8 hectares a year earlier. And the Monarch Butterfly Biosphere Reserve in Michoacan. Mexico, lost trees at a higher rate than it did in 2019.
With climate change as the monarch butterflies’ biggest challenge, they are faced with many dangers, such as drought, deforestation(滥伐森林)and struggle to breed. These dangers affect the whole migration and hold back population growth. Female monarchs lay their eggs on milkweed flowers, which have been heavily affected by the wild weather from spring and summer of last year. Because of this, the development of butterfly eggs was also affected.
Since 2013, Mexico has seen a rapid drop in the number of migrants arriving to the area. The effects of climate change and deforestation have become an important sign that action needs to be taken to make sure of a healthy migration for monarchs going forward. If not, it’s their possible dying, out that wall fall unto our hands.

3 . Rainforests provide much of the world’s oxygen. People have been trying to protect them for years. But another type of forest, the cloud forest, is just as important to humans.
These forests are at the tops of mountains, generally near the equator (赤道). These wet, wooded mountaintops are mainly in African and Central and South American countries. They are called “cloud forests” because their height allows for the formation of clouds among the trees. The trees in these forests pull water out of the clouds. The water gathers on the leaves and falls into small rivers below, which flow into towns at the bottom of the mountain. The yearly rainfall in these areas is about 180 centimetres. Cloud forests can pull in up to 60 percent of that. The water is important to the plants and the people in the area. It helps them survive.
Cloud forests are also home to countless species of plants that can’t be found anywhere else. One small cloud forest has as many types of plants as there are in all of Europe. In fact, there are so many that scientists haven’t made a complete list of them yet.
These forests are being destroyed at an increasing speed. Trees are being cut down, and roads are being built in their place. Some people have a goal to get government money to protect the forests. But they have had little success so far. Another way is to take the place of the destroyed plants with new ones. That, too, has been difficult because the plants are so special. There’s plenty of work to be done, but saving the cloud forests is still possible with creative solutions.

4 . It used to be that a “green classroom” referred to the colour of paint on the wall. But today’s green classrooms are greener than that! New “green” classrooms help schools save money and provide clean environments where students learn better.
Many classrooms are going green by adding solar panels to their roofs. The solar panels collect energy from the sun and use it to power lights and computers. The panels help make green classrooms grid-neutral, which means the panels create at least as much electricity as the classrooms use. In addition, new lighting and air systems can be programmed to lower energy costs and water use.
Many new “green” classrooms are built by using recycled materials. Some even use pieces of material from blue jeans to insulate walls and roofs. The old-jean insulation cuts heat and air conditioning bills.
Green schools feature many other new ideas. Some classrooms are painted using special odor-free paints that help improve indoor air. Some use no glues that add chemical smells to the air. Others use triple-pane windows and skylights to help keep classrooms warm in cold weather and let in lots of natural daylight.
Experts say the benefits of building greener classrooms go beyond cost savings. Studies show that a healthful environment with good air quality can cut colds and flu by more than 50 percent. That means fewer sick days for students and teachers. Studies have shown that natural light and other green features improve student learning and test scores too.

5 . 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.

The environment pollution was more and more serious today. We have no clean water to drink it because of water pollution. And when trees cut down, some animals disappear. There is more and more dirty smoke in the air. People’s health has been great affected by air, noise and water pollution. Many people have died of diseases causing by pollution. In order to live the better life, it’s time for us to protect our world.
Firstly, we shouldn’t throw away rubbish everywhere. And we should recycle, reduce and reuse things, that saves money and reduces pollution. Use things so long as possible. Don’t use plastic bag. Besides, we must plant more trees and stop people cutting it down. We hope our world will be more and more beautiful.

8 . Twelve years ago, a young traveler named Rhett Butler from San Francisco, California, visited the Sabah rainforest on Malaysian Borneo. In one area of the rainforest, he watched a bird flying through the trees. The beautiful sight left quite an impression on him. But weeks later, back home, Rhett Butler got the news that trees had been cut down for their wood in the area he visited.
That experience led Rhett Butler to begin writing a book about rainforests and threats (威胁) to their existence. But he did not publish the book. Instead, in 1999, he used his research for the book to create a website. The site is Mongabay.com. His purpose was to inform the public about tropical rainforests. But the subject quickly developed. As a former businessman, he became a respected writer of science and environmental stories.
The popularity of Mongabay.com attracted advertisers. Small ads on the site pay for its operations. Mongabay.com has grown and led to other sites. For example, there is a site for children which is called kids mongabay.com. Another one, WildMadagascar.org, is all about the island nation that Rhett Butler calls his favorite place.
To keep his website going, he travels around the world on several major trips each year. His working tools are a laptop computer, cameras and sometimes diving equipment. He often calls on experts for information. For example, he interviewed Alison Jolly, a top expert on lemurs (狐猴). He interviewed Rodney Jackson, a biologist who established the Snow Leopard Conservancy.
Stories like these have made Mongabay.com a favorite place on the Internet for researchers, students and teachers. In April, Time. Com. named it one of the fifteen top climate and environment websites in the world.

9 . The rapid increase of the oil price has brought the world to its senses. Scientists are seeking suitable alternative (替换) but so far in vain. They are considering how they can make better use of the two other major fuels, coal and natural gas, but they have found that neither can replace oil in their economics. In recent years, there has been a growing concern for the environment and coal is not a popular fuel with environmentalists. Natural gas, the purest of the three fuels, is also the most limited in supply.
The answer would seem to lie in nuclear power stations. They need very little fuel to produce enormous amounts of power and they do not pollute the atmosphere. Their dangers, however, are so great and the costs of building them are also high. Not only could one accident in a nuclear power station spread as much radioactivity (放射物) as a thousand Hiroshima atom bombs, but the radioactive waste from these stations is extremely dangerous.
Scientists have recently turned their attention to natural sources of energy: the sun, the sea, the wind and hot spring, of which the sun seems the most promising source for the future. Houses have already been built which are heated entirely by solar energy. However, solar energy can only be collected during daylight hours, and in countries where the weather is unreliable, an alternative heating system has to be included.
However, many scientists are optimistic that new ways of generating large amounts of energy will be successfully developed, but at the same time they fear the consequences. If the world population goes on increasing at its present rate, we may, in fifty years’ time, be burning up so much energy that we would damage the earth’s atmosphere. By raising the temperature of the atmosphere,we could melt the Arctic and Antarctic ice-caps and change the pattern of vegetable and animal life throughout the world——a frightening possibility.

| B．it cannot generate large amounts of power |
| C．it may use up enormous amounts of fuel |
| D．it may cause great danger to us if not properly handled |
10 . 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.
