When you throw something in the trash, soon a garbage truck will come to take it away. Then where does it go? That depends on where you live. Different towns deal with trash in different ways. | |
Recycling A recycling truck picks up paper, cardboard, metal, plastic and glass. These go to the recycling plant to be sorted and made into new things. |  |
Incinerator An incinerator is a huge stove that burns trash to make heat and electricity. The ash that’s left gets buried in a landfill. Trash ash can be poisonous, so it has to be stored carefully. But is takes up a lot less room than just plain trash. |  |
Compost Food waste might go to a composter. In a compost heap (堆肥堆), bacteria and worms break down dead plants and old food. They turn it in into good, rich oil. Some people keep compost heaps in their gardens. Big commercial composters handle waste from restaurants and farms. |  |
Landfills Some trash gets buried in landfills. A landfill starts as a big hole. Trucks dump trash. Big earth movers push it into place and crush it down. They cover the trash with dirt to keep scavengers (食腐动物) away. The bottom of a landfills is lined with a barrier to keep bad things from leaking into the ground. Pipes drain away liquid. When the landfill is full, it’s covered with earth. It might become a park or lawn. |  |

【推荐1】On a boat near Costa Rica, a team of marine biologist is helping a turtle. The animal is having trouble breathing, and the team discovers why—there is something inside its nose. A scientist tries to extract the object, but the turtle cries in pain. Finally after eight long minutes, a long object is pulled out. It is a 10-centimeter plastic straw.
The video of the turtle's rescue has been viewed millions of times on YouTube. It has helped raise awareness of a growing problem: The world's seas are full of plastic. Since 2000, there has been a huge increase worldwide plastic production, but we recycle less than one-fifth of it. A lot of this plastic waste' ends up in the ocean. Today, scientists think about 8.1 billion kilograms goes into the sea every year from costal regions. Most of this plastic will never break into little pieces.
This ocean plastic hurts millions of sea animals every year. Some fish eat plastic because it is covered with sea plants, and it looks and smells like food. “In some cases, eating sharp pieces of plastic can seriously hurt sea animals and even result in death,” says marine biologist Matthew Savoca.
Plastic is useful to people because it is strong and lasts a long time, but this is bad news for sea creatures who eat or get stuck in it. According to Savoca, Single-use plastics are the worst.” These are items that are used only once before we throw them away. Some common examples include straws, water bottles, and plastic bags. About 700 sea species have been caught in or have eaten this kind of plastic. Luckily, the turtle survived and was released back into the ocean. How will plastic affect sea animals in the long term? “I think we’ll know the answers in 5 to 10 years’ time,” says an expert from Columbia University. But by then, another 25 million tons of plastic will already be in the ocean.

【推荐2】Last month, a part of the Negro River in the Amazon rainforest reduced to a depth of just 12.7 metres, its lowest level in 120 years, due to the lack of rainfall. In Lake Tefé, about 500 kilometres away, more than 150 river dolphins were found dead, not because of the low water levels, but probably because the lake had reached temperatures close to 40℃.
“The Amazon rainforest in northern Brazil is experiencing a tough time and it is the sum of three things,” says Luciana Gatti, a researcher at Brazil’s National Institute. “The first is deforestation, which is turning rainforest into a drier, hotter place,” she says.
“Additionally, El Ninio climate pattern has begun and it makes things worse,” adds Gatti. El Niño is a phenomenon which occurs every two to seven years. During El Niño, winds that usually blow from east to west along the equator (赤道) are weakened or even turn the other way round. This leads to the change of rainfall in South America, causing dry air in the north, where the rainforest lies, and damp air in the south. As a result, countries in the south are currently greeted by heavy rains, while the Amazon is experiencing the lowest rainfall levels from July to September in 40 years.
The third factor is the unusual warming of the water in the northern Atlantic Ocean. The warming of these waters causes the Inter Tropical Convergence Zone (热带辐合带), a region of intense cloud and rain formation, to shift north. The ITCZ takes the storms with it, away from Brazil, and causes less rainfall than usual.
Although it is hard to predict when the next drought might strike the Amazon, studies show that climate change is messing with the timing of El Niño. “The tendency is that we have stronger and more frequent crises,” Gatti says. This could be a disaster for the Amazon rainforest, already hit by deforestation and a warming, drying climate.” The forest’s tipping point is coming closer—and it’s coming quick.

| Dear Principal Stanton, The date for our annual Desert Path Pride Spirit Week is rapidly coming and the Student Council has been discussing some new ideas about how to celebrate school pride this year. Since Spirit Week is the week before scheduled testing, we would like to suggest combining student festivities with preparation for testing. We want to assure you that all activities would focus on academics while providing fun for those involved. Our plan for the week is as follows: Monday—Math Day would include fun math games in the classrooms and school-wide activities such as guessing the number of bricks in a building, recording times at relay races, and competitions for multiplication facts. Tuesday—Reader’s Roundup would focus on books and authors. Students and teachers can come dressed as their favorite author or character from a book. This day would be great for the contest of “Best Reader”. Older students can share reading time with younger aged buddies. Wednesday—Writer’s Day would display student writing from previously held competitions for types of writing like poems, stories and essays. Of course there would be prizes given for outstanding writing in each category. Thursday—No Fear Day would be where we have our spirited assembly (集合) to get us ready for testing. The Student Council could even put on a skit(短剧) showing how all of us at Desert Path are ready for test week. These are just a few of the ideas we are asking you to consider. We would like to have the opportunity to meet with you and discuss our plan and to hear what ideas you may have for Spirit Week. Please let us know when you can schedule some time to meet.

【推荐1】Jason had been watching the X Games on TV. Athletes from all over the world were competing in the most amazing sports. Just then his grandmother walked into the room. ''I want to be extreme. Would you really let me do that? You always worry about my safety! '' said Jason.
''You will have to follow some rules, '' said his grandmother. ''You can only ride in the park —never on the streets. You have to promise to wear a helmet (头盔). If you hurt yourself too much, I have the right to take your skateboard away. Is it a deal? ''
''You bet! '' Jason was so excited that he jumped off the sofa. A week later he had a board and a helmet.
On Saturday, his grandmother dropped him off near the park. He was happy to have a grandmother who let him try new things.
Kids in the park were moving quickly up and down the ramps (坡道). They flew into the air and landed as easily as birds. When he watched the X games, Jason felt like he was doing the tricks himself. But watching these kids up close, he knew that none of it was going to be easy. He felt a little bit scared.
Very slowly he carried his board to the ramp. Taking a deep breath, he put his right foot on the board. He kicked off with his left foot. For a few seconds he glided (滑行) along, just waiting to fall. Then he came to a stop. Kicking off again, he waited for the worst to happen. Again, he stayed up. The third time he kicked, lost his balance, and fell hard on his left knee.
It hurt, but it was no big deal! Why had he been so scared? Now he felt calm because things had gone wrong, and he was fine!
Next time he kicked off harder and went fast and farther. ''Excellent! '' said a girl as she passed him. ''Extreme! '' laughed Jason to himself. ''Not quite.''

【推荐2】We thought we had it all---a beautiful house, three healthy children and one more on the way, two cars, a couple of four-wheelers for entertainment---and we loved it. Then, the market turned and my husband’s job at a construction company was gone. The company was closing down for good.
We both started looking for jobs right away, but there weren’t any to be found. With each passing day we were getting increasingly worried and we continued to work together in order to pull our family through. The more we pulled together, the closer we got. I felt feelings of admiration for my husband that I hadn’t felt in years.
That’s why it was so hard for me to watch him blame himself for our present situation. I continually asked him to stop, but he seemed to want to punish himself for not having a job.
Finally, one afternoon I pulled him aside and said, “We have four healthy children. That's what's important. That makes you a rich man.” “But what if we lose the house? They’ll hate me---you’ll hate me,” he replied.
I smiled at him and put my hands on both sides of his face to make him look me in the eye.
“No matter where we live I will be happy---as long as I have you.” I smiled again. In all the struggling together I had found that deep love for him that I had on the day we said “I do”.
I could see his shoulders and neck relaxed. He held me close and we were able to talk and plan and dream together in a way that we hadn’t for quite some time. It was a turning point for us as a couple and a family.
We are still struggling for our better life, but I consider us well-off because we have something that money can’t buy and no one can take away from us.

【推荐3】When life gives you pineapples—and hundreds of millions of tons of pineapple waste—what do you do? Engineers in Singapore and Vietnam decided to turn all the waste into something useful—the heat barrier for their pineapple juice. Not only does their new material keep drinks cool better than many commercial coolers, but it could also offer a final resting place for the world’s pineapple waste.
To find a use for those leftovers, the researchers mixed pineapple fibers, which they cut up in an electric device, with a sticky agent as a solvent. They then treated the mix with sound waves at frequencies greater than 20 kHz and heated it in an oven at 80℃for 2 hours. The suspension that formed was then cooled before being freeze-dried.
The result was a pale yellow aerogel (气凝胶) that is lightweight, flexible, and more than 96% porous (多孔的)—qualities that make it an ideal material against both heat and sound.
When the researchers wrapped a sheet of the pineapple aerogel around a military-style canteen bottle, they found that the aerogel could provide three times the heat exchange reduction of commercially available alternatives—they reported this month inMaterials Chemistry and Physics. The gel-wrapped bottle kept -3℃water cooled below 0℃for 6 hours and liquid heated to 90℃above 40℃for 2.5 hours. What’s more, the pineapple gel also acted as a sound barrier; in another test, the gel did a better job of preventing noise from getting in or out than Basmel, a popular kind of sound barrier.
The findings provide a new, eco-friendly approach to recycling agricultural cast-offs—and a good excuse to get a better electric device for your kitchen.
1. Why do engineers come up with the idea of the heat barrier?| A．To lower the cost of heat barriers. | B．To make good use of pineapple waste. |

【推荐1】Wildlife faces threats from habitat destruction, pollution, and some human activities. Although protecting wildlife may seem too hard at times, even small actions in your own neighborhood can help protect many different animals. Here are some tips on how to protect wildlife through small actions.
Create wildlife-friendly areas in your backyard.
When trying to make your garden more beautiful, you can choose plants that can provide food and shelter for the native wildlife. This will also help cut down on pollution.
Besides, bird or bat houses in your yard or garden can attract and shelter more species.
Avoid harming the natural ecosystem (生态系统) in your backyard.
Some plants from other places can kill or harm the native plants that provide food and shelter for wildlife.
Have a greener lifestyle.
By using less water and fewer fuels, you will do good to help protect the wildlife around you. Take buses or the subway if you can, turn off the electric devices when you're not using them, take showers for a shorter time, and keep the temperature in your room at or below 68 Fahrenheit degrees in winter.
Buy products that are friendly to wildlife.
Don't buy products that are made from endangered animals. Keep in mind that some endangered animals are killed by traps, or hunters who are eager to earn money with them.
Donate money to organizations that protect wildlife and their habitats.
You can give money to organizations of groups that protect wildlife in your neighborhood, thus promoting their work.

【推荐2】Whether it is for a special festival, to express thanks or to just let someone know that you care about them, giving gifts is a common custom. The purpose of giving gifts may be similar, but the tradition varies from country to country. A gift of respect in one place may be considered rude in another. Take a look at three unique gift-giving traditions.
India
If you’re invited to someone’s home in India, you should bring a small gift, whether it’s a box of chocolates or some flowers. Gifts shouldn’t be wrapped (包裹) in black or white colors. because they are considered unlucky. Instead, use bright colors such as green, red or yellow. When giving money for any occasion, it should have an odd number (奇数) value. That’s believed to bring good luck. Instead of receiving a gift with both hands, Indians generally only use their right hand because left hands are considered unclean.
Japan
For most Japanese, the ritual (礼节) of giving presents is more important than the gifts themselves. The correct way is to present or receive gifts with both hands. Every gift should be wrapped. That’s because uncovered gifts are considered disrespectful. To show politeness and thanks, those who are receiving the gift may turn it down once or twice before finally accepting it. Gifts should be given in pairs, but four should be avoided just like in China. Lucky numbers also include eight. Eight is said to bring prosperity.
Native America
While it may be common for guests to prepare gifts for hosts, this is different in Native American communities. From weddings to birthday celebrations, guests are the ones who receive gifts. Gifts are usually homemade arts and crafts that are made by hand to show love, respect and appreciation.
1. What kind of gift would you bring to an Indian home?| A．Some chocolates in a green box. | B．Flowers wrapped in black paper. |
| C．Sixty dollars in a yellow envelope. | D．Seventy-five rupees wrapped in white paper. |
| A．To get another better gift. | B．To be more polite and thankful. |
| C．To refuse one’s kindness. | D．To be more outgoing and active. |
| A．To list some attractive festivals. | B．To compare some countries. |

【推荐3】What is the single most effective way to reduce greenhouse-gas emissions? Go vegetarian? Replant the Amazon? Cycle to work? None of the above. The answer is: make air-conditioners radically better. On one calculation, replacing refrigerants(制冷剂) that damage the atmosphere would reduce total greenhouse gases by the equivalent of 90bn tonnes of CO2 by 2050. Making the units more energy-efficient could double that.
Air-conditioning is one of the world’s great overlooked industries. Automobiles and air-conditioners were invented at roughly the same time, and both have had a huge impact on where people live and work. Unlike cars, though, air-conditioners have drawn little criticism for their social impact, emissions or energy efficiency. Most hot countries do not have rules to govern their energy use.
Yet air-conditioning has done quite a lot things to benefit humankind. It has transformed productivity in the tropics and helped turn southern China into the workshop of the world. In Europe, its spread has pushed down heat-related deaths ten times less than what it was in 2003, when 70,000 people, most of them elderly, died in a heatwave. For children, air-conditioned classrooms and dormitories are associated with better grades at school.
Environmentalists who call air-conditioning “a luxury we cannot afford” have half a point, however. In the next ten years, as many air-conditioners will be installed around the world as were put in between 1902 (when air-conditioning was invented) and 2005. Until energy can be produced without carbon emissions, these extra machines will warm the world. At the moment, therefore, air-conditioners create a vicious cycle. The more the earth warms, the more people need them. But the more there are, the warmer the world will be.
Cutting the impact of cooling requires three things (beyond turning up the thermostat(温度调节器) to make rooms less Arctic). First, air-conditioners must become much more efficient. The most energy-efficient models on the market today consume only about one-third as much electricity as average ones. Minimum energy-performance standards need to be raised, or introduced in countries that lack them altogether, to push the average unit’s performance closer to the standard of the best.
Next, manufacturers should stop using damaging refrigerants. One category of these, hydrofluorocarbons, is over 1,000 times worse than carbon dioxide when it comes to trapping heat in the atmosphere. An international deal to phase out these pollutants, called the Kigali amendment, will come into force in 2019. Foot-draggers should approve and implement it; America is one country that has not done so.
Last, more could be done to design offices, malls and even cities so they do not need as many air-conditioners in the first place. More buildings should be built with overhanging roofs or balconies for shade, or with natural air-circulation. Simply painting roofs white can help keep temperatures down.
Better machines are necessary. But cooling as an overall system needs to be improved if air-conditioning is to fulfil its promise to make people healthier, wealthier and wiser, without too high an environmental cost. Providing indoor sanctuaries of air-conditioned comfort need not come at the expense of an overheating world.
1. Why does the author think air-conditioning is an overlooked industry？| A．Because many hot countries haven’t put the energy-controlling rules into force. |
| B．Because it has caused the same impact on people’s life and work as automobiles have. |
| C．Because it has brought great economic, physical, and educational benefits to humans. |
| D．Because it doesn’t get the due criticism for its environmental impact as automobiles do. |
| A．The price of air-conditioning will go up due to the large demand for it. |
| B．A high environmental cost will come along with the air-conditioning service. |
| C．Environmentalists are expecting extra machines which can warm the world. |
| D．Governments partially agree that air-conditioning is a luxury we cannot afford. |
| A．Manufacturers should only stop using hydrofluorocarbons. |
| B．People should avoid turning up the air-conditioners to have cool rooms on hot days. |
| C．People should adopt more environmentally-friendly materials when designing buildings. |
| D．Governments should give a green light to the agreement on eliminating the pollutants. |
| A．arouse people’s attention to the global warming. |
| B．appeal for the global joint efforts to combat global warming. |
