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.

2 . In 2010, Barack Obama was to pay a visit to Mumbai’s Gandhi Museum, where palm trees full of me dotted the grounds. Before his visit, Indian authorities removed every last sign of me from the premises for fear that the president of the United States would be taken out by one of me landing on his head.

Let’s get this out of the way: My reputation as the killer fruit of countless innocents was then and still is a myth. A repeatedly misinterpreted 1984 study greatly exaggerated the number of deaths I caused by hitting and the vicious rumor spread. Today, the only things about me to die for are the sometimes too-delicious foods you humans make with me, which include macaroons, pi a coladas, rich curries, and custard pies. A decade ago, health experts briefly gave me a halo because some of my saturated fat (饱和脂肪) called medium-chain triglycerides, can raise beneficial HDL cholesterol. And no wonder: I’m a long-lasting source of food and water, and my fibrous flesh is used to make rope, mats, mattress stuffing, and fishing nets. My shell can be turned into charcoal for fire or used as a bowl or musical instrument. My leaves are used for thatching roofs and making brooms and baskets, while my trunks are used for building houses, boats, and drums. My tree’s roots have many folk medicinal uses and produce pigments that become dyes — and their frayed ends have even been repurposed as toothbrushes.

In World War II John F. Kennedy was trapped on an island. He scratched a message for help into a coconut shell, and two coast-watchers delivered it to Allied forces, who managed to rescue him. The coconut shell sat on JFK’s desk in the Oval Office throughout his presidency and now is a center-piece of the John F. Kennedy Library in Boston — as proof that we coconuts don’t take lives, we save them.

3 . To solve a big environmental problem, chemists in the Czech Republic have been thinking small. Really small. Their new minirobot has one purpose: to help clean up tiny bits of plastic polluting waterways across the globe.

Each new robot is no bigger than the tip of a sharpened pencil. They are magnetic (有磁性的) and shaped like stars. When sunlight hits them, they produce chemical reactions that push them through water in a specific direction. When they find a piece of plastic, they stick to it and start to break it down. When the light goes out, they let go and are free to be used again.

“This work is great,” says Douglas Blackiston at Tufts University in Medford, Mass. He’s a biologist who did not work on the project but knows about such devices. He’s been designing robots out of living cells, including some that might help with pollution cleanup. Speaking of the new one, he mentions that, “These robots can eat plastic. They chew it up. Or they can recover it and be collected with a magnet. Scientists love robots with all these capabilities. ”

Chemist Martin Pumera at the Czech University of Chemistry and Technology in Prague led the project. He studies ways to build microrobots. About a decade ago, he says, scientists began developing tiny bots that could move themselves in water. Then, they had to find them a mission and thought “Let’s make them do something useful.” Since then, Pumera has focused on the problem posed by microplastics, which are everywhere—from the bottom of the ocean to air blowing onto ice atop mountains. They’ve turned up in drinking water, both bottled and tap water, and some studies estimate that trillions of pieces of plastic end up in the world’s waters. The plastic has many sources, from drinking straws and shopping bags to laundry and cleaning wipes. Plastic doesn’t easily degrade or fall apart, and that’s always been one of its appeals.

Pumera says his final goal is to make cheap and environmentally friendly robots that can be used anywhere in the world.

1. What do the new robots mainly do?

A．To collect tiny bits of plastic in the sea	B．To push the pollution in water away
C．To help do research into the plastic	D．To deal with the plastic in water

2. How do the new robots get powered?

B．Because of the challenges from the plastic

C．Because he was asked to do so by other scientists

D．Because he was inspired by the invention of microrobots

4. What is the best title of the article?

A．Small robots, big dreams	B．No plastic in water anymore!

5 . Known for its skyscrapers and megamalls, Singapore is perhaps not so well-known for its abundance of trees. But according to a new study, it ranks top in the world for urban tree density (密度).

According to the study, almost 30% of the city-state is covered by trees, which is nearly 4% more than joint second-place cities Sydney, Australia and Vancouver, Canada. The study was completed by researchers at the Massachusetts Institute of Technology (MIT) and the World Economic Forum (WEF) and has measured the urban green canopy (天蓬似的树荫)of 17 key cities around the world using Google Street View data. Of the 17 cities, Paris has the fewest trees with only 8.8% of its urban area covered by greenery. “The green canopy is an important and integral part of urban life. Trees help mitigate extreme temperatures, provide a natural relief from traffic jam and noise, and improve the quality of life for those living in urban environments,”says Treepedia, the website which hosts the findings of the study. The project has the aim of encouraging city planners and residents to do more to promote greenery in their cities.

Nicknamed the City in a Garden, Singapore’s top place spot is no surprise. Parks such as the Bukit Timah Nature Reserve, the Botanic Gardens and the newer Gardens by the Bay super park — home to around 400,000 plants—have no doubt contributed to its winning place. The city also has a considerable number of roof gardens and “skyrise” greenery on the front wall of buildings—in fact this type of greenery alone has increased from 61 hectares in 2013 to 72 hectares in 2015. Singapore’s National Parks Board also manages around two million individual trees along streets, and in parks.

6 . How to grow tomatoes?

Given the proper climatic conditions, you can grow tomatoes nearly anywhere. Before you grow tomatoes, check if your area has the right climatic conditions for this purpose.     1     And if it doesn’t, just give up this idea.

    2    One is to grow them from seed and the other is to grow them from the plants. The seeds usually take six to eight weeks to grow. If you don’t know how to grow tomatoes from seed, you can consider buying the plants directly. Many of these plants can be found at most garden centers.

Tomatoes don’t grow well in cool conditions.     3     Tomatoes require areas with full sun and should have enough protection from strong winds as well, that’s more, they require a lot of water; therefore, you had better water your tomato plants regularly.    4    

Check tomato plants daily for any ripe produce. Picking often helps more to grow. Once the end of growing season is coming, it’s helpful to remove any flowers as well.     5    If you still have a lot of green tomatoes during this time, go ahead and pick them. These can be stored in a warm area up to four weeks, and then they will turn red.

8 . Two little girls,14-year-old Cindy and 12-year-old Lucy, wrote to a newspaper office, asking some fast food restaurants to stop giving away free plastic (塑料) toys. Many people read the letter and supported them.

“We have been learning all about the environment at school and the problem of plastic. It made us very sad to see how plastic harms wildlife and pollutes the ocean, and we want to change this.That’s why we want the fast food restaurants to think of the environment and stop giving away plastic toys with their kids meals.” the two girls wrote in their letter.

“We like to go to eat in fast food restaurants, but children only play with the plastic toys they give us for a few minutes before they get thrown away. In the end, they will harm animals and pollute the sea. We want anything they give us to be sustainable (可持续发展的), so we can protect the earth for us and for future humans,” they continued.

The letter made a large number of readers pay attention to them. The number of people who supported them almost doubled after reporters followed the two little girls.

9 . Actress Hayden Panettiere recently got into trouble with Japanese fishermen as she tried to stop them from killing dolphins.

The 18-year-old star with some other surfers sailed out to reach the dolphins in order to stop them from being driven into a nearby pool and killed, but the six surfers, from Australia and the United States, were stopped by a fishing boat before they could reach them. The fishermen blocked their way with a boathook (钩篙). It was an ugly, unfriendly and life-threatening struggle before the surfers were forced to return to the beach. It is believed that the dolphins were later taken into a pool and killed.

Panettiere, who is a brave surfer and loyal animal protector, made up her mind to save the dolphins of Japan and said, “It was really frightening. Some of us were hit by the boathook, but in the end all we were really worried about was the dolphins. It was so sad. We were so close to them and they were jumping out of the water to see us.” Breaking down in tears, she added, “One little baby dolphin stuck his head out and looked at me and the thought that it’s no longer with us is really hard to take.”

The surfers left the country to avoid arrest (逮捕) by the Japanese police. Panettiere is now back in Los Angeles.

More than 22,000 dolphins are killed by fishermen in Japan every year. Many Japanese believe dolphins should be treated like fish. They have been hunting dolphins for centuries and see any criticism (批评) of this as an attack on their culture.
