Every day we use energy. We use it for cooking, for heating and for lighting our cities. The energy comes from many different     1     (source). It can come from the sun, wind and water, but the energy we depend on the most comes from deep inside the Earth. These include coal, oil, and natural gas.

These fuels come from the remains of plants and animals. It takes millions of years     2     (make) them. However, with the world’s population     3    (grow), more and more of these fuels are dug up from the ground. Yet these fuels are non-renewable. When they     4    (use) up, they will be gone forever.

We need to have a strong sense of     5    (responsible) and it’s high time for us to think about     6     we can help save energy and preserve these fuels.

What about turning off anything     7     (electricity) we are not using? That’s a start! We can also recycle things such as newspapers, cans, bottles, and plastic—including plastic bags. Plastic bags start out as either oil     8     coal, and one big city can use millions of plastic bags in a year. When we use recycled things, it takes less energy     9     making something new.

Cars consume a lot of fuel, but there     10     (be) a variety of measures that car owners can take to preserve fuel. Try asking your family whether we can take a bus or walk instead of using the car.

And keep the out-of-town place as a backup.

Run practice drills (演习). It’s important    9    (practice) what to do in case of a natural disaster,    10    (especial) if you have children. Each year, you’d better organize a practice drill for a possible disaster. And try to let all the family members take part in it.

7 . “How many of us as children have stared up at a church-like top of a giant tree and climbed it in wonder, which is a rally special part of our lives?” asks Bill Laurance, a tropical ecologist at James Cook University. “The leaves of big trees in forests are spreading out in all directions. We’re faced with organisms that have evolved for long periods of ecological stability.”

“There’s a lot to discuss on the issue,” says David Lindenmayer, a conservation ecologist at the Australian National University. “Climate change will mean that, in some forests, big trees won’t reach the same sizes they used to.” The effects of climate change, including long droughts, more invasive species and so on increase the simple physical challenges that big trees face in pulling water from their roots to their leaves and withstanding windstorms.

Lindenmayer and Laurance define “large, old trees” as the largest five percent mature trees within a species. The flexible definition means that in some forests, the large, old trees might be only 20 meters tall and 100 years old.

These large, old trees control the surrounding plant communities, affect water and nutrient distribution, and provide food and shelter for wildlife. “They’re really the breadbaskets of the forest,” says Laurance. “This is a very environmentally and ecologically important group of organisms, and they need special care and handling.” Determining the distribution and habitat requirements for large, old trees in the landscape is the first step towards ensuring their survival, “We have to ensure that what we’re thinking is long-term, to match the way these trees have existed for hundreds or even thousands of years,” says Laurance. “It’s going to be a real challenge to keep some places where there is still wildlife and the big church-like trees that we all really care about.”

8 . Plastic is nearly everywhere — in shoes, clothes, refrigerators and construction materials. But this highly useful material can have a major defect. Made from oil and slow to break down, conventional plastic is not environmentally friendly. Today, researchers discuss inventing what they say should be a safer, biodegradable (可生物降解的) alternative made from fish waste— heads, bones and skin— that would otherwise likely be thrown out.

If developed successfully, fish-oil-based plastic could help meet the considerable need for more sustainable plastic, says Francesca Kerton, the project’s investigator. Previously, others have developed new plastic using plant-based oils. However, this too comes with a disadvantage: the crops that produce these oils require land that could otherwise be used to grow food.

Leftover fish struck Kerton as a promising alternative. Salmon (鲑鱼) farming is a major industry for coastal Newfoundland, where her university is located. After the fish are processed, leftover parts are often thrown away. Kerton and her colleagues developed a process for turning this fish oil into a plastic-like material. But does the plastic smell fishy? “When we start the process with the fish oil a slight kind of fish smell, but as we go through the steps, that smell disappears,” Kerton says.

In other experiments, they have begun examining how quickly the new material would likely break down once its useful life is over. Kerton put pieces of it in water, and to speed up the degradation for some pieces, she added a chemical capable of breaking down fats like those in the fish oil. Under a microscope, she later saw microbial (微生物的）growth on all of the samples, even those that had been in plain water, an encouraging sign that the new material might biodegrade quickly, Kerton says.

Kerton now intends to study the material’s physical properties to see how it might in real-world applications, such as in packaging or fibers for clothing.

The most     1     earthquake in the past 40 years caused a tsunami that     2    into coastlines across Asia yesterday，killing more than 6,500 people in Indonesia, India, Thailand, Malaysia, and at least four other countries. Fishermen, tourists, hotels, homes, and cars were     3     away by huge     4     caused by the strong earthquake that reached a magnitude of 9.0. The undersea quake     5     around 7:00 a.m., Sunday off the coast of Indonesia’s Sumatra Island. In that area alone, at least, 1,870 people were killed.

10 . A handful of old mobile phones lay in a grey bucket. These outdated devices, which are about to be chopped into thousands of pieces, will be given a second life as recycled e-waste. But many phones won't.

According to the latest estimates, the world gets rid of approximately 50 million tonnes of waste annually. E-waste is full of dangerous materials that can cause damage to human health and the environment if not managed properly. But only 20 percent of global e-waste is recycled.The rest ends up in landfill, or burned—or is not recycled at all.

And yet,Switzerland is a good example of how to deal with the growing environmental issue. The country collects and recycles roughly 7S percent of this discarded material. This is thanks to a strong voluntary take-back system, where consumers can take e-waste to a reclining collection point or any electronic shop retailer（零售商）. A recycling station can be found within at most 300 meters from any residential area. Everyone gets involved. Switzerland's e-waste system is unique and can't be easily copied-due to a strong recycling culture within the country.

However, Switzerland faces the same global challenges as every nation.The built-in lithium batteries（锂电池）aren't easy to take out. The only way to remove these potentially dangerous components is with a bar and hammer. This poses a significant risk to those handling the goods. As such, producers need to be more transparent(信息透明的) and show more clearly where the harmful substances are, and how they can be removed.

Once the battery is removed, e-waste is sorted into different component parts—-metals, plastics and other materials. Roughly 70 percent of the device can be recycled. The material that cannot be recycled is used for other purposes like construction material or is burned to generate energy. Mobile phones—from a material perspective (角度), from a value perspective，and also from an environmental impact perspective -are very important.

For the past 15 years, Switzerland has been actively encouraging and supporting electrical waste disposal practices. They are happy to share their knowledge, experience, lessons learned, and they are happy if other people pick up on it.
