2 . The South Bronx is one of the poorest and most polluted places in America, with smog-choked freeways and smelly wastewater treatment plants.

“We’re a dumping ground,” Omar explains. “All the garbage from the rest of New York City ends up here.”

But Omar started looking at garbage in a different way. “A lot of what people throw away is perfectly good,” he says. “Just look at that stuff from construction sites—doors, sinks, toilets, People will buy those things. It’s only called garbage because somebody threw it away.” Omar was just out of college and working for an environmental group called Sustainable South Bronx when he started considering how to get this “good garbage” to people who could use it. Instead of destroying old things, why not clean them up and resell them? Why not hire people in the community to do the work? Better yet, why not make this business a “cooperative,” which means the people working in the business own it and share the profits?

Out of this, Omar started the first cooperative in the country devoted to reusing construction waste. To start his business, Omar put up advertisements along the trash-filled neighborhood streets, looking for people to work with him. He soon found four other devoted workers. They rented a warehouse and started looking for donations of used materials.

In April 2008, Omar’s cooperative, Re Builders Source, opened its business and began selling construction supplies to neighborhood builders and home owners. With the help of city officials, he also began planning a new training program to help local residents learn the skills to get good jobs that help the environment and even start their own cooperatives. Workers were trained to carefully take buildings apart so that things like doors and windows can be reused instead of being sent off to a landfill. Deconstructing buildings this way could be a huge industry with many good jobs for people who need them.

“If you have a use for something, “Omar says, “it’s no longer waste.”

3 . 阅读下面材料, 在空白处填入适当的内容(1个单词)或括号内单词的正确形式。

People in Bangladesh and India are struggling as they face serious flooding caused by early heavy rains. The floods     1     (cover)roads, bridges, and entire villages so far.     2     (million)of people have been left helpless by the floodwaters. The flooding in Bangladesh is the     3     (bad)in nearly 20 years. The United Nations(UN)says that the flooding has affected at least 4 million people in Bangladesh. The floods have hit the districts of Sylhet and Sunamganj     4     (especial)hard. In these areas, about 2 million people were left cut off from areas nearby.

The flooding     5     (cause)by heavy rains. Two rivers     6     run near Bangladesh’s border with India, the Surma and the Kushiara, hit the highest water levels ever recorded. The government has made the     7     (decide)to close almost 600 schools. Some are to be closed because of flooding. Others will be turned     8     emergency shelters. Bangladesh is a low-lying country, and often has floods.     9     same is true for parts of India. But normally, most flooding happens later in the year. Scientists say that because of the climate crisis, extreme weather     10     (include)heat waves, severe storms, heavy rains, and flooding is becoming far more common.

4 . This summer, nearly 65 percent of the United States is experiencing “unusually dry” weather. More than 109 million people are living under drogue conditions.     1     So how to garden when there’s a lack of water?

    2    Newly planted trees and shrubs(灌木)should be put on the top of the watering list. They require regular watering until their roots get deep into the soil. That process can take a full year. Vegetables such as beans, cabbage, and lettuce also have high water needs. None will likely survive with little water.

Most plants require an average of 2 to 4 centimeters of water each week under normal conditions. That need could increase, however, during periods of extreme heat, when the soil dries out more quickly.     3     Divide it over two or three times per week.

Use deeper, less-frequent watering instead of daily sprinkles(洒水)which can be wasteful? Watering deeply also leads to stronger, deeper roots that are better able to support plants when there’s no surface water. So avoid using overhead sprinklers.     4     You can place watering devices on the soil directly over roots.

Consider using recycled household water, also called gray water, to water plants. Unsalted water left over from boiling eggs or vegetables provides extra nutrients(营养物). Dish and bath water that is not too soapy will not harm plants. And water captured(捕获)while cleaning fruits and vegetables can be used around the garden.     5    .

A．So learn how to water plants correctly.

B．So make good use of water in your house.

C．You should water newly planted trees regularly.

D．A lot of them have plants or yards to worry about.

E．First you should decide which plants need water the most.

F．Do not offer your plants their weekly water needs all at once.

G．They wet the leaves and other areas instead of directing water to plant roots.

5 . With greater climate disasters lying ahead, it is natural for us to make every effort to stop a series of floods, unusual snowstorms, and alarming reports from scientists. For many of us, part of that means running out to buy reusable drinking tubes, organic cleaners, and packaging-free products.

However, before you are joyful of your “green” purchases, take a second to consider a principle that should be obvious: simply consuming less is better for the planet. After all, every new item a factory pumps out requires some resources to produce. But in the confusing stream of environmental news, this simple truth can get lost. Take plastic bag bans for instance. If your city is getting rid of single-use shopping bags, it can be tempting to pay for that fashionable organic cotton bag hanging in the check-outline of supermarkets. However, experts who have analyzed the data on environmental impact insist that growing cotton is actually no better for the Earth than producing the conventional plastic bag. Any bag you already own is your best bet for carrying your groceries if you care about sustainability.

It is not just the Earth that will be happier if you buy less. You will feel more contented too. There is a common view that green buying patterns mean people are going green. However, it doesn’t seem to be that way. Reduced consumption has positive effects on increased well-being, but you don’t see that with “green” consumption.

Many studies have shown that materialism in general makes us unhappy and lonely. It is perfectly possible to be a materialist and an environmentalist at the same time. Lusting (欲望) for every new “green” product on the market might make you feel good about yourself but it presents the same emotional traps as lusting for whatever the Joneses next door are buying. If you relieve yourself of that burden of ownership, most people report feeling a lot better and freer.

6 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式

Early in February some volunteers in the United States posted dozens of     1     (photo) on the social media,     2     (show) that the physical condition of the giant panda Ya Ya in the Memphis Zoo was worrying. Having been hungry for     3     long time, it looked bony, weak and dirty. The poor condition soon caught worldwide concern.

From    4     we have learned so far, Ya Ya has serious skin disease and digestive system problems. The situation is not very optimistic,     5     makes people very sad. The American animal protection group “In Defense of Animals” (IDA) has released a video in which Ya Ya was seen circling around where she lived.     6     is reported that the panda now weighs     7     (little) than normal, eats little and shows obvious signs of stereotyped behavior and even self-harm.

Since the Chinese Association of Zoological Gardens received reports of Ya Ya’s poor health condition, the relevant authorities     8     (take) immediate action to deal with the problem. Both China and the US have been actively discussing ways to speed up the procedures necessary for Ya Ya’s return to her home country. A team from Beijing Zoo has arrived in the US to assist Memphis Zoo with Ya Ya’s care and work with them to ensure that she is properly     9     (feed), cared for and then transported back to China.

A source says that if the procedures go     10     (smooth), Ya Ya will return to China in April.

7 . Cities have been described as essential to climate change solutions, but they can also raise the kinds of ecologists that will bring us into a more comprehensive biological future.

As a black wildlife biologist from Philadelphia, I stood out among my coworkers. My presence in ecology has challenged assumptions about not only what a biologist looks like, but also where a biologist comes from. In the U.S., ecology was and is mainly white and conducted in rural landscapes, but I had no history of camping, fishing, hunting or hiking. I had yet to recognize that Philadelphia, with its four seasons and richness of squirrels (松鼠), row homes and festivals, was actually my first ecological classroom. There I witnessed wild cats eating birds and rats, people shooting bats from their homes and snakes being killed by lawn mowers (割草机). This is as much ecology in action as anything we witness in fields and forests.

Urban wild animals exhibit many features and behaviors that set them apart from their rural twins: they may be bigger, eat more diverse food sources, are active at different times of the day, move differently and have different personalities. Some biologists argue they are even “smarter”. Besides, urban wildlife balances more risks—such as road chemical poisons and diseases from domestic animals—with rewards. Some of those rewards come from humans providing food and some from the distribution of our parks and water bodies.

In our professional lives as biologists, living with such wild animals can make us more tolerant of species diversity, which can benefit the natural world. Nature is no longer only primitive wilderness but includes sounds of human laughter and garbage trucks. We expect more biologists from urban settings because urban environments naturally train keen observers who are the future of ecology.

8 . Victoria Falls is one of the Seven Natural Wonders of the World. Statistically speaking, it is the largest waterfall in the world. Victoria Falls is located on the border between Zambia and Zimbabwe. The falls are also close to the border of Botswana. The Zambezi River, which originates in northern Zambia, serves as the falls’ water source.

There are basically two seasons for the Victoria Falls area. The rainy season runs from late November to early April with the remaining months accounting for the dry season. One would imagine that the rainy season with more water would make the falls more spectacular (壮观的), however, the additional water and subsequent mist(水汽) in the air makes it nearly impossible to see the base of the falls.

The months of June and July are probably the best time to view the falls. The water levels are still high enough to show the beauty of the falls, but the amount of water is less, creating less mist and more visibility of the falls.

As you move into the later part of the dry season, August through October, it is quite possible that you will see more rock face than falls. However, this also opens the door for walking across the top of the falls, which can be a unique and exhilarating experience as well.

During the rainy season and high water, Victoria Falls can be a challenge to capture (抓拍) with a camera because of all of the mist in the air. However, this increases the probabilities that you will be able to capture rainbow images around the falls.

The lower water levels can create more dramatic pictures with various rocks cropping out between the falls. You should also be able to see the canyon and base of the falls. You will also be able to walk across the top of the falls and take images down the face of the falls.

1. Where does the water source of Victoria Falls originate?

A．In northern Zambia.	B．In southern Zimbabwe.
C．At the border of Botswana.	D．Between the border of Zambia and Zimbabwe.

2. When is the best time for travelers to walk across the top of the falls?

A．From November to April.	B．From August to October.
C．In the months of June and July.	D．In the months of May and June.

3. What does the underlined word “this” in paragraph 5 probably refer to?

A．A camera.	B．High water.
C．The rainy season.	D．All of the mist in the air.

4. What are the last two paragraphs mainly about?

A．Travel strategies at different water levels.	B．Challenges for falls travelers to overcome.
C．Photo opportunities in different seasons.	D．Different views of the falls all the year round.

9 . Scientists from Deakin University in Australia have traced how about 30 species changed across various time periods in response to rising temperatures. They searched through nearly 100 past studies by other researchers, and tracked comparisons that date back a century or two in some cases. They found many creatures are changing the sizes and shapes of certain body parts.

“Warm-blooded animals in the wild rely on their own bodies to avoid overheating. They release heat through their appendages (肢体),” explains Sara Ryding, who led the study. For little creatures. like mice, tails do the job. For birds, their bills (喙) do the work.

The animals’ shape-shifting changes make sense, researchers say. In biology, an established concept called Bergmann’s rule shows that creatures that live in colder climates tend to be larger and thicker than those closer to the equator (赤道). Later, a biologist, Joel Asaph Allen further expanded the concept, saying that animals that adapted to cold climates have shorter limbs (肢) and bodily appendages — to keep the warmth in. For similar reasons, in hotter climates, warm-blooded animals"appendages become larger, relative to their body size. Larger appendages can help animals release more heat into the surrounding air.

Ryding’s team also conducted various field studies. One of them measured the bills of Galapagos finches from 2003 to 2011 and found they enlarged in response to temperature rises. Other data the researchers analyzed focused on European rabbits, which were brought to Australia and settled in areas with different weather. Those that found themselves in hotter places developed longer ears over time.

However, the researchers aren’t sure whether this shape-shifting is a good development. If larger ears or bills can help the animal cool off, that’s a good thing. But certain changes may damage some creatures’ ability to hunt for food. “If you’re a hummingbird and your bill is getting broader and wider, it may become too large to effectively feed on flowers where you’ re drawing your nutrition from,” says Ryding.

1. How did the scientists carry out their study?

A．By experimenting in the wild.	B．By referring to previous data.
C．By exploring a variety of fields.	D．By collecting information worldwide.

2. Why is Bergmann’s rule mentioned in Paragraph 3?

A．To offer background information.	B．To raise doubts about a concept.
C．To stress the role of weather changes.	D．To explain the researchers’ findings.

3. What do the researchers want to find out about animals’ shape-shifting changes?

A．Their rules.

B．Their reason.

C．Their effects.

D．Their frequency.

4. What does the text mainly tell us?

A．Animals are good at surviving tough situations.

B．Animals base their body changes on their environments.

C．Climate change forces animals to change their habitats.

D．It is wise of animals to use their different body parts effectively.
