Leonora, a 51-year-old from the Philippines,     1    (make) women’s dresses out of waste materials in recent years since she believes     2    (wear) such clothes can be cheap and look good. To make her dresses, she uses     3    foot-operated sewing (缝纫) machine to join together the waste materials, including recycled newspapers, plastic wrappers and rice bags,     4    which Leonora makes her designs. The bubble (泡沫) wrappers from delivery packages are nice-looking and suitable for a good design,     5    (particular) for making wedding dresses. They are also used for everything from wedding decoration to birthday     6    (party).

In Asia, there is plenty of waste material for Leonora to apply. Most of the world’s ocean waste     7    (carry) by Asian rivers. And her country, the Philippines, is responsible for one third of Asia’s ocean plastic pollution.

“The dresses are really     8    (impress). It’s important to recycle such materials so we can help our earth,” said Lalaine     9    buys clothes from Leonora.

Most of her dresses are used in the beauty     10    (compete) and are popular with young girls. “I get delighted whenever they win. The designs are simple, but they still win,” she said.

3 . How did Cape Town, South Africa, get into a Day Zero situation—when the city’s taps would go dry because its reservoirs (水库)would become dangerously low on water? The city gets its water from six reservoirs in Western Cape province, which usually ____________ during the rainy season, from May through August. But since 2015 the region has been suffering from the worst drought (干旱)in a century, and the water in those reservoirs____________ tremendously. Compounding the problem, Cape Town’s population has grown substantially, increasing ____________ . The city actually did a pretty good job by reducing leaks in the system, a major cause of water waste, and has even won awards for its ____________ policies. But the government of South Africa was slow to declare a national disaster in the areas hit hardest by the drought, paving the way for the recent ____________.

Cape Town is not ____________ . Since 2014 southeastern Brazil has been suffering its worst water shortage in 80 years,___________ decreased rainfall,   forestation and other factors. And many cities in India do not have access to municipal water for more than a few hours a day, if at all.____________ , the city of Shimla ran out of drinking water in May, urging locals to beg tourists to stay away from the popular Himalayan summer resort.

In the U.S., the situation is somewhat better, but many urban centers still ____________ water problems. Californians recent multiyear drought led to some of the state’s driest years on record. Since about half of the state’s urban water usage is for landscaping, it was able to cut back on that fairly easily. But cities that use most of their water for more essential uses, such as drinking water, may not be so ____________ .

____________ , steps can be taken to avoid urban water crises. In general, a “portfolio approach” that relies on multiple water sources is probably most ____________ . Cape Town has already begun implementing a number of water projects, including tapping groundwater and building water-recycling plants. Many other cities will need to repair existing water infrastructure (基础建设)to cut down on leakage. City leaders should be thinking about meeting long-term needs rather than just about ____________ requirements. Good organization and financial accountability are equally critical. And planning efforts should include diverse stakeholders (利益相关者)from the community. One major challenge is providing services to informal areas, which develop without any government foresight. Such regions often ____________ basic resources一a well-planned water supply among them. The global community has an opportunity right now to take action to prevent a series of Day Zero crises. If we don’t act, many cities may soon face a time when there isn’t a drop to ____________ .

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.

5 . 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.

Several strange things happened before the Earthquake hit Tangshan. Some     1    (smell)gas came out of them and chickens were too nervous to eat. And in less than one minute, the whole city lay in     2    (ruin). The country united as one to relieve the disaster, and soldiers were sent to dig out those who     3    (trap) under the damaged buildings.

8 . Oceans are an appealing target for renewable energy production. Waves produce 32,000 terawatt-hours of natural energy per year — for reference, the entire world uses around 23,000 terawatt-hours every year.

The advantages of wave power are clear.     1     Turbines produce electricity through the power of waves, making them a completely pollution-free, renewable energy source. And the amount of kinetic energy in a wave is huge that energy is used to produce electricity. There is also a lot of potential because many countries have access to an ocean that can help power their electric systems. Also, waves are hardly interrupted and almost always in movement.     2    

But the disadvantages of wave energy are serious too. Building factories or electrical wires directly on the beach might prove challenging.     3     Local fishing zones could be affected or the factories could lead to more coastal erosion. High cost is a problem too. Wave power is a rising energy technology in the early stages of development, so calculating the costs is difficult.     4     Because constant movement can lead to more breaking, wave energy factories will most likely need regular and costly maintenance.

    5     For many ocean-bordering countries, wave energy will be a great addition to the newable energy mix. The bottom line is that wave power has enormous global potential. However, the industry needs more funding and research to finalize the technology involved so that countries can begin adding wave energy to their renewable energy source.
