In their spare time, most young people like to enjoy     1     (they)and play on their smartphones. But Li Ruxue is different. He often walks around a forest alone,     2     (isolate)himself from the outside world. “Though the lifestyle is a little bit tiring, it’s meaningful,” he often said.

In college, Li actively took part in field research. After graduation, he joined a gibbon protection organization where what he mainly needs to do is     3     (pick)up gibbon waste. The gibbon is a top-level state-protected animal     4     population is smaller than that of wild giant pandas. So over the past four and a half years, Li     5     (follow)gibbons and collecting their waste for researchers. Li said the job relies heavily on luck and     6     (persevere). But he has never regretted his choice or felt alone.

Like Li, Chu Wenwen, 27, has also worked to protect animals. As her father is engaged     7     wildlife research, Chu has long been surrounded by wild animals. She followed in her father’s footsteps. Listed as     8     first-class state-protected animal in China, the Mengxin beaver is found only along the Ulungur River in Xinjiang’s Altay prefecture.To protect them, Chu initiated the “beaver canteen” program, which     9     (eventual)attracted over 1 million internet users to donate snack money.

According to Fan Pengfei,     10     (ecology)protection as an industry can provide only a few jobs,most of which are in research institutes and nongovernmental organizations. He has seen more and more young people take part-time jobs as journalists, photographers and so on to raise public awareness of wildlife protection. “Young people are the future of the world and the future of global biodiversity conservation,” said Fan.

At the Shishou Milu National Nature Reserve in Hubei Province, about 2,000 creatures wander freely. Their numbers include 460 deer born this year, showing that the species,     1     was once endangered in China in the early 20th century, has staged a remarkable     2     (recover).

Often     3     (refer) to as sìbuxiang, a milu deer seems to consist of parts of various creatures. It has antlers (鹿角) like other deer, but seems to have the head of a horse, the feet of cattle and the tail of a donkey (驴).

    4     one of the animal’s three major protected areas in China, the Shishou reserve was established in 1991. Close to the Yangtze River, the area has a complete wetland ecosystem,an ideal habitat for the deer. Its conservation story provides     5     example for other endangered animals under a threat of extinction.

    6     (ensure) a safe environment, two engineers and eight rangers (护林员) are sent to get around the reserve. Advanced technologies are applied to help observe and analyze     7     (they) habits and environment. The efforts of those responsible for the deer have     8     (significant) resulted in the increase in numbers.

In the     9     (country) three major protected areas the Nanhaizi Milu Park in Beijing, the Dafeng Milu National Nature Reserve in Jiangsu Province, and the Shishou reserve——the number of the animal     10     (increase) from 39 to over 10,000 since 1986.

6 . When a heavy storm hit, residents of the floating community of Schoonschip in Amsterdam had little doubt about whether they could ride it out. They tied up their bikes and outdoor benches, and checked in with neighbors to ensure everyone had enough food and water as their neighborhood slid up and down its steel foundational pillars (支柱), rising along with the water and going back to its original position after the rain stopped.

“We feel safer in storm because we are floating,” says Siti Boelen, a Dutch television producer who moved into Schoonschip two years ago. As sea levels rise and supercharged storms cause waters to rise, floating neighborhoods offer an experiment in flood defense that could allow coastal communities to better fight against climate change.

A floating house can be constructed on any shoreline and is able to deal with rising seas by remaining on the top of the water’s surface. Unlike houseboats, which can easily be moved and relocated, floating homes are fixed to the shore and are usually connected to the local sewer (污水管道) system and power grid. They are structurally similar to houses built on land, but instead of a basement, they have a concrete hull (船体) that acts as a counterbalance, allowing them to remain stable in the water.

Severe wind and rain, or even the passing of large cruise ships, can make the buildings rock. Siti Boelen, the Schoonschip resident, says that when she first moved in, stormy weather made her think twice. “You feel it in your stomach,” she says, adding that she has gotten used to the feeling. Floating homes also require extra infrastructure and work to connect to the electricity grid and sewer system.

But the benefits may outweigh the costs. “If there are floods, it’s expected that many people will move to higher ground. But the alternative is to stay close to coastal cities and explore expansion onto the water,” says Rutger de Graaf. “If you consider that in the second half of the century, hundreds of millions of people will be displaced by sea level rise, we need to start now to increase the scale of floating developments.”

7 . Many poor children in Africa struggle on tuition for an education. However, a new school has been asking their pupils to pay for classes with _________.

Every week, students _________ the Akshar School are required to line up and “pay” for their classes using grocery bags _________ at least 25 pieces of plastic waste they _________ from around their homes and communities.

Parmita and Mazin, the couple _________ for the new school, were _________ to launch the campaign after witnessing their students being forced to _________ the acrid smell of burning plastic. That’s _________ before the school was opened in 2016, local families and communities _________ burned plastic waste as a means of keeping warm and fueling fires.

Now, the plastic is being collected and recycled at the school’s own recycling center. The school __________ the trash into Ecobricks by compressing (压缩) about 40 pieces of garbage into a(n) __________ plastic bottle.

Furthermore, the school’s older students can work part-time at the center as an additional source of __________.

Now the school owns over 100 students __________ the ages of 4 and 15. Since the school’s __________ curriculum has attracted more and more __________ to enroll, the couple plan on opening another 100 schools over the next five years.

8 . As environmental awareness has risen in the world, attitudes to sightseeing have changed. It is exciting to visit remote forests or spot rare species in those mysterious countries. However, with flights or long road journeys involved, traveling to far-away destinations is carbon-intensive, and conservation can be made more difficult as well as assisted by sightseers. Therefore, people and authorities have been trying to maximize the benefits while minimizing the harms by advocating domestic tours.

Most people, who take most holidays, understand better than ever that there are costs as well as benefits associated with exploring. One of the six pledges made by an environmental campaign launched last month-The Jump, is to “holiday local”, taking short-distance flights once every three years and long-distance flights very rarely. On a higher level, some governments are working on this as well. Colombia, for example, recently introduced laws aimed at promoting sustainable tourism.

Fortunately, the UK’s national parks and countless other landscapes mean that there is no shortage of special places for domestic nature tourists to visit. One recent survey found that Windsor Great Park and Kew Gardens have become Britain’s most popular attractions, while in this special time there have difficulties for indoor spaces which do not apply to outdoor ones. Some companies that formerly ran foreign trips have adapted to the infectious disease by taking people to watch dolphins and other marine life off British coasts instead. This is not to minimize the destruction of nature that is also taking place, But as we lace an increasing environmental emergency, it is essential to appreciate the nature that surrounds us. In a small way, outings to watch dragonflies, seals, or be surrounded by trees could help us to focus on what matters.

9 . In the northernmost edge of Colombia sits the coastal town of Acandí. Access to the town is only by water or air; there is no road that leads there. The residents there are faced with the struggles of balancing livelihoods while protecting biodiversity.

In the past, traditional community fishing methods, passed down by the elders, focused on the reasonable fishing and management of resources. However, the introduction of large-scale trawling vessels(拖网渔船) decades ago gradually depleted the area’s fishing resources, leading to damage to marine(海洋的) life seriously.

Jesús Antonio Julio Cuestas, who serves in the region’s conservation and management of marine resources, stresses the bad impact of these developments and calls for new fishing techniques. “Fishing and conservation co-exist as long as we have good management practices and reasonable use of our fishing resources,” says Cuestas. He and other officials actively monitor fishing activities in Acandí. Each morning, they visit the fish markets to gather data on fishery resources—including prices and sizes—to monitor the state of the local fishing industry.

Along with Cuestas, the fishers work to reduce their impact on the marine ecosystem. By changing fishing methods and adopting new practices, they aim for a more balanced approach to fishing. “This year the local fishermen have not used the trawl net s that were causing the death of the leatherback sea turtles,” explains Cuestas proudly. Changes include the efforts of boats to protect the seagrass that serves as feeding grounds for marine life and an end to fishers throwing net s where turtles lay their eggs.

This marine reserve in Acandí, Cuestas believes, is their greatest treasure. He attaches great importance to working together with local residents to improve the quality of life while preserving the marine ecosystem. By doing so, he imagines a picture where individuals from the fishing community can pursue various careers, such as engineers or lawyers, proudly stating that they are the products of the fishing tradition in Acandí.

10 . It is a well-known fact that plastic bottles, which take hundreds of years to rot, are harmful to our environment. However, efforts by environmentalists to encourage consumers to switch to alternatives, like water fountains or reusable bottles, have not been very effective. The U.S. alone uses over 50 million plastic bottles annually, 80% of which end up in landfills.

To try to stop that, Rodrigo García González, Pierre Paslier and Guillaume Couche from the Imperial College London have been working on a revolutionary solution — water wrapped inside an eatable container made mostly from seaweed. All the customer has to do to relieve his/her thirst is pop the entire drop into the mouth.

The inventors, who have been working on the Ooho bubble since 2014, use a simple two-step cooking process called spherification (球化) to create the delicate container. They begin by dipping a frozen ball of water or juice into a chemical solution (溶液). This helps form a layer around the liquid. The ball is then absorbed in a solution made from seaweed extract. This creates a second layer, helping strengthen the structure so that the water or juice does not leak. In addition to saving our environment, the biodegradable (可降解的) packaging costs just two cents each, making it cheaper to produce than plastic.

After three years of perfecting the design, the inventors, who recently raised over 1 million USD from a financial activity, are ready to bring the Ooho bubble to local market. However, there are a few challenges that still need to be overcome before the product’s launch. In addition to getting accustomed to the taste of the covering, each eatable container contains just a mouthful of water, requiring consumers to drink multiple bubbles to relieve their thirst. There is also the issue of finding an eco-friendly packaging to transport the bubbles so that they remain clean and do not burst. Hopefully, the inventors will find ways to handle the issues so that we can reduce, or perhaps even remove, plastic bottles.
