A
People all are looking for ways to save energy and natural resources (资源) to protect our environment. Here’s an example of saving water.
A doctor called Jack Todd, is very interested in cleaning water as well as saving money, so he has tried many ways, and in the end he developed a small and affordable system to clean waste water— the Living Machine. The machine can clean waste water in our home and in our business.
The machine can clean waste water. First, the waste water goes into a big plastic tank. In the tank, the wastes start to break down. Second, a few days later, the water is brought into a greenhouse full of plants and fish. With the help of sunlight, plants and animals, many chemicals can be removed from the water. That makes the water cleaner. Then the water can be used for washing or bathing. Though it cant be used for drinking or cooking, the water is clean enough to water the flowers, wash the dog and bathe.
This technology is good for the environment. It can also help to save fresh water and it can help provide the unpolluted water. If we take actions to do something to save energy on the earth, our planet will have a longer life and our life will be better.

Teens take a stand
COP 26 was held in Glasgow, Scotland. It’s the United Nations’ climate change conference (会议) on dealing with global warming.
Many world leaders took part in the event. But there were also lots of teenagers from different countries there to make their voices heard. At 15, my friend Chelsea Liang from Edinburgh was one of the young participants at COP 26. I was able to ask her some questions about her experience there.
Liang participated as a junior representative (代表) of C Team, a non-governmental organization, which organized all the events at the China Cooperate Pavilion (馆). “I helped set up the stadium, hosted meetings, engaged in youth events, and joined the audience in the meetings. I met many young people who really care about the environmental problem,” said Liang.
“The major topic from teen participants is that governments act to limit global warming to 1.5℃,” she said. “Some of them met in Glasgow to call for a better future.”
The well-known British naturalist David Attenborough was the eldest participant of the event. Liang said that the 96-year-old made an inspiring speech.
“He said, ‘In my lifetime, I’ve seen a terrible decline (衰退). In yours, you could and should witness a wonderful recovery. That desperate hope is why the world is looking to you and why you are here.’ His words encouraged me to take action,” Liang said. “And I realized that as teenagers we are able to come up with good ideas to make a difference.”
“I have seen that over the last two weeks, companies and people are doing much more than expected. Social awareness of global warming is only increasing. I am optimistic (乐观的) about the future,” said Liang.

Ben and his classmates are watching a DVD about the environment. This is the introduction to them.
A long time ago, most towns and villages were very small. The number of people who lived in every country was much smaller than it is today, too. There was no heavy industry, but only agriculture, arts and crafts (手艺). And none of these things damaged our environment. People did not use chemicals. There were no motor vehicles. There were no factories. There was, therefore, very little pollution.
Sadly, our environment is much dirtier than it was in the past. This is a problem because the best way for us to be healthy is to live in a clean environment.
The air and the water are much dirtier than they used to be. The air is full of pollutants (污染物) of various kinds-smoke from cars, factories and things like insect sprays (喷雾). The water is polluted by chemicals from factories and fuel from ships. These mean that we are gradually destroying one of our major food sources-the oceans of the world.
In the DVD, we will try to find the ways to make our environment cleaner and the ways to stop future pollution. We hope you will learn how to make the world a cleaner and healthier place.

John Muir was a protector（保护者）of nature. He set an example that each of us can follow to protect the natural areas around us.
The first way we can follow Muir’s example is to discover our local natural areas. 31 He once walked one thousand miles from Indiana to Florida.
32 Muir loved to explore（探索）the outdoors. He learned everything he could about rock plants and animals. From his exploring, he came to realize that the wilderness, places where people do not live or build, is an important gift. Muir made a decision that his life’s goal was to protect this gift.
Muir’s greatest example for us is his work to protect nature. He shared its beauty by writing books. 33 In winter, he enjoyed its “pearl gray belt of snow（珠灰色雪带）”. However, he also saw sheep eating Yosemite’s plants and people cutting down its trees for wood. Muir gave talks and wrote books about these dangers. President Theodore Rooevelt was so impressed（给……留下深刻印象）after hearing that Muir visited Yosemite that he signed a law making Yosemite a national park in 1890. 34
We can find our own pieces of nature to explore, learn about and protect. We can write to our local newspapers about nature’s beauty. 35 We can all follow John Muir’s footsteps.
A．Muir was a great traveler.
B．He was trying to protect nature all the time.
C．Another way to follow Muir is to learn about nature.
D．This meant that the US government would take care of it.
E．He climbed Yosemite’s peaks（山峰）and described them as “clothes in light”.
F．We can also tell people how to help care for it.
G．Exploring nature is a good way for us to learn more about nature.

The Earth Needs a Helping Hand
The Earth is getting warmer because of the activities of people. We cut down and burn 46 and send gases into the air with our cars and factories. Can we do anything about it Sure. We may not be leaders or scientists but we can play our part in 47 the planet. Here are two ideas.
Ride Bikes to School
Do you 48 to school by bus or by bike If you bike, you are doing 49 good for the Earth. Buses, cars, trains and planes produce a lot of carbon dioxide. If you live near to your school, why not bike there on warm spring mornings Or you can 50 walk to school to save energy.
Wash in the Green Way
Do you help your mom and dad wash clothes Then wash them 51 an energy-saving way. A recent study by Cambridge University found that 60 percent of the energy used on a piece of clothing is 52 in washing and drying it. Over a lifetime, a T-shirt can send up to 4 kilograms of carbon dioxide into the air.
53 you wash your own clothes, wash them in cold or warm water to save energy, but not hot water. When they’re clean, dry 54 clothes the natural way, by hanging them with a line rather than 55 them in a dryer. In all, you can cut the carbon dioxide used in washing by 90 percent.

Frank went diving (潜水) in Australia 58 he was 16. He was shocked to see 59 (much) plastic bags than fish in the sea. Frank made up his mind to clean up the ocean. However, everyone told him that there was nothing he could do to stop plastic bags from 60 (go) into the ocean. But the young man didn’t give 61 . He spent several months studying plastic pollution. Finally, he came up with a science project using floating barriers (漂浮的栅栏) for collecting the waste. That is to say, instead of using nets and ships to collect the plastic bags, the barriers can make the plastic bags 62 (come) together with the help of natural ocean currents (洋流) and wind. What’s more, the collected plastic bags can 63 (recycle) and made into products or oil.
Finally, Frank 64 (win) prizes for the project, but that was not enough for him. He wanted to make it a reality. In 2013, he set up The Ocean Cleanup. Together with scientists, engineers and volunteers, the young man is working hard to clean up the ocean. In the 65 , this great project will help make our world a better place.

Antarctica (南极洲) is known for being a large land of ice and snow, a place too cold for most life. However, the land is slowly starting to turn warm. According to The Guardian, the Antarctic has shown a new high temperature for the first time on record, raising fears of climate change in the world’s coldest place.
On Feb. 9, Brazilian researchers at Seymour Island reported a temperature of 20.75 ℃ on the icy land of Antarctica. It was almost a full degree higher than the past record of 19.8 ℃, taken on Signy Island in January 1982.
This record-breaking reading (数据) was taken at a watch station in the northern part of Antarctica. According to Brazilian scientist Carlos Schaefer, the temperature was recorded during a 20-year-long research project. The purpose of this project is to study the effect that climate change has on the permafrost (永冻土) within the area. Permafrost is the earth that stays icy for at least two years.
Although this is a first record high for Antarctica, Schaefer pointed out that “We can’t use this to predict climate changes in the future. It’s simply a sign that something different is happening in that area.”
But in fact, the last high temperature reading was around 19 ℃. These higher temperatures can cause ice in Antarctic area to melt (融化). This melted ice leads to a rise in sea levels that can put the coast areas in danger. It’s believed to be behind an alarming drop of more than 50 percent in the number of penguins, which are dependent on sea ice.
Like American writer Ernest Hemingway once said, “The Earth is a fine place and worth fighting for.” We should do everything we can to help save our planet. Otherwise, it may become too hot for us to live in.
根据短文内容，回答问题。
66．What has happened to the Antarctica leading to fears of climate change again
67．Who reported a new high temperature for the first time on record in the Antarctica
68．What is the research project for according to the passage
69．How can higher temperatures influence coast areas
70．What can you learn from the last paragraph

71．例文
Saving the Earth
How to protect the environment has become one of the biggest problems in the world. There are many kinds of pollution around us, such as air pollution, noise pollution, water pollution and light pollution. We can find that pollution not only damages our environment but also harms people’s health. So we should not throw rubbish everywhere. Some factories pour waste water into the rivers and the lakes. The behavior of these factories will pollute the water. So we should stop factories from pouring waste water directly into rivers.
We have only one earth. We must keep our environment clean and tidy. We must try our best to protect her, and make our home more beautiful.
