4 . When discussing the causes of animal endangerment, it is important to understand that individual species are not the only factors involved in this difficult situation. Endangerment is a broad _________, one that involves the habitats and environments where species live and interact with one another. Although some measures are being taken to help specific cases of endangerment, the universal problem cannot be solved until humans _________ the natural environments where endangered species live. There are many reasons why a particular species may become endangered, but habitat destruction is on top.

Our planet is continually changing, causing habitats to be altered and modified. Natural changes tend to occur at a(n) _________ pace, usually causing only a slight _________ on individual species. However, when changes occur at a fast pace, there is little or no time for individual species to _________ and adjust to new situations. This can create disastrous results, and for this reason, rapid habitat loss is the primary cause of species endangerment. The strongest _________ in rapid habitat loss are human beings. Nearly every region of the earth has been affected by human activity, particularly during this past century. The loss of microbes in soils that _________ supported tropical forests, the extinction of fish and various aquatic species in polluted habitats, and changes in global climate brought about by the _________ of greenhouse gases are all results of human activity.

It can be difficult for an individual to _________ the effects that humans have had on specific species. It is also hard to identify or ____________ human effects on individual species and habitats, especially during a human lifetime. But it is quite ____________ that human activity has greatly contributed to species endangerment. ____________, although tropical forests may look as though they are thick and healthy; they are____________ highly susceptible (易受影响的) to destruction. This is because the soils in which they grow ____________ nutrients. It may take centuries to re-grow a forest that was cut down by humans or destroyed by fire, and many of the world’s severely threatened animals and plants live in these forests. If the current rate of forest ____________ continues, huge quantities of plant and animal species will disappear.

5 . Medi Bastoni, a 43-year-old father of four from Indonesia, is walking 800 km from his home on a volcano in East Java to Jakarta. He is doing it _________ in the hope of drawing attention to the archipelago’s (多岛屿的) quickly _________ forests.

He set out on his _________, backward journey in mid-July, with the _________ of reaching the capital by August 16, a day before the Southeast Asian nation’s independence day anniversary. He just took a short break when he was _________. “Of course I’m exhausted, but I’m ___________ to do this to fight for the next generation and I just make my _________ to do it,” Bastoni said. “My home is ___________ all of its trees so I have to do something. I can _________ the pain and tiredness.”

Bastoni says that when he arrives, he hopes to __________ President Joko Widodo and highlight the ____________ of deforestation (滥伐森林) across the archipelago, __________ at his home on Mt Wilis, a dead volcano. Indonesia __________ from one of the high rates of deforestation in the world, according to Greenpeace. Bastoni __________ 20 to 30 km backwards every day under the sun, with a rear-view mirror (后视镜) __________ to his backpack to avoid bumping into objects. Along the way, supporters cheer him on, __________ him meals or a place to stay overnight. But in order to stay ____________, Bastoni always leaves at dawn.

“Walking backwards is meant as a __________ to Indonesians to reflect on the __________ and remember how national heroes __________ for the good of the country,” he said.

6 . One of the most pressing challenges the world will face in the next few decades is how to relieve the growing stress that human activities are placing on the environment. The consequences are just too great to_______. Wildlife habitats are disappearing as new developments._______more land. Plant and animal species are getting in_______at a greater rate now than at any time in Earth’s history. As many as 30 percent of the world’s fish stocks are over-exploited. And the list goes on.

_______, there is reason to have hope for the future. Advances in computing power and molecular biology are_______the tremendous increases in scientific capability that are helping researchers_______a better understanding of these problems. Recent development in science and technology could provide the_______for some major and timely actions that would improve our understanding of how human activities affect the environment.

One priority (优先处理的事) for research is improving hydrological (水文学的) forecasting. It is_______that the world’s water use will triple (变成三倍) in the next two decades. Already, widespread water_______has occurred in parts of China, India, and North Africa. The need for water also is taking its toll (造成痛苦) on fresh water ecosystems in the United States. Only 2 percent of the nation’s streams are considered in good__________, and close to 40 percent of native fish species are threatened with__________.

To__________outbreaks of infectious diseases in plants, animals and human, more study is needed on how parasites (寄生虫) and disease-carrying species — as well as humans and other species they__________— are affected by changes in the environment. The overuse of antibiotics both in humans and in farm animals has__________the growth of antibiotic- resistant microorganism (微生物). Researchers can__________new technologies in genetics and computing to better monitor and predict the effects that environment changes might have on disease outbreaks.

7 . Thomas Dambo, an artist from Denmark, is using his sculpting（雕刻）skills to help thousands of urban birds worldwide._______by the belief that humans should live_______with other species, he uses reused wood to build houses for birds wherever he goes.

Dambo's birdhouses are creative and_______, combining（结合）wonderful design with reused wood and other junk materials that he_______collects. Through his_______, he wants to show that everyone can create something beautiful from trash, and he also hopes to_______others to waste less of the world's resources.

Dambo describes his own_______as colorful, positive, childish, and fun. He also makes birdhouses that easily_______city environment, so birds can feel_______in them. Some of his past projects________a collection of birdhouses made from________skateboards. He also sculpted 600 birdhouses for a festival, and later gave them away to people after the activity, only________that they hang them up and send him pictures.

Dambo is working with a large Danish company on a project that uses their waste wood for large birdhouse________In this way, he hopes to________more people and just teach more people about recycling and the________of protecting the world. He dreams of having a big recycle plant next to his workshop someday, so people could just bring him their________to work with.

________birdhouses, Dambo has built several other structures from recycled wood, but his main________now is creating abundant housing structures for birds. People always________whether birds use the houses. Dambo tells them the fact that birds will move into the houses if there are birds in the area. Dambo is so________about birdhouses that he's also built a large red one for himself!

8 . Hailing from Sweden, “plogging” is a fitness craze that sees participants pick up plastic litter while jogging adding a virtuous, environmentally driven element to the sport. Plogging appears to have started around 2016, but is now going global, due to increasing awareness and __ over plastic levels in the ocean.

The appeal of plogging is its __—all you need is running gear and a bin bag, and the feeling of getting fit while supporting a good cause. By adding regular squats(蹲) to pick up junk and carrying __ to jogging. we can assume the health benefits are increased.

Running and good causes have always gone __ — just think of all the fundraising marathon runners do. But there couldn’t be a more on-trend way of keeping fit than plogging.

Anything that’s getting people out in nature and connecting __ with their environment is a good thing, says Lizzie Carr, an environmentalist who helped set up Plastic Patrol, a nationwide campaign to __ our inland waterways of plastic pollution. There’s been a real __ in the public mindset around plastics, helped by things like Blue Planet highlighting how disastrous the crisis is,” she says.

We need to keep momentum high and the pressure up, and empower people through __ like plogging and Plastic Patrol.

The plastic Patrol app allows users to __ plastic anywhere in the world by collecting discarded items, photographing them and __ to the app, giving us a better knowledge of what sorts of plastic and which brands are being thrown out. “I’d urge all ploggers to get involved,” adds Carr.

Plogging isn’t the first fitness trend to combine running with a good cause, Here are some of our favourites:

Good Gym

Its idea is simple: go for a run, visit an elderly person, have a chat and some tea, and run back.

__ among the elderly is a growing problem in the UK. With over 10,000 runs so far, __, Good Gym is finding a solution.

Guide Running

Guide runners volunteer their time to helping blind people get __. By linking themselves together, the __ —impaired individual can feel safe while both work of a sweat.

___for the Homeless

Start-up Stuart Delivery and the Church Housing Trust collaborated last year in bringing clothing and healthy food to the homeless. Deliveries are mostly made by bike, so those who deliver keep fit while helping rough sleepers(无家可归者).

9 . This summer we said goodbye to unnecessary plastic waste. Starbucks committed to ________ plastic straws in all locations by 2020, IKEA banned all single-use plastics from its stores, and entire cities banned the use of plastic bags and straws. And now we have one more thing to add to our consciousness-raising list: People are starting to understand the ________ of contact lenses（隐形眼镜）.

According to a new research out of the American Chemical Society, 20 percent of people who wear contact lenses throw them away in the toilet or sink. But as medical ________, contact lenses are specifically designed to be resistant in touch environments, and ________ they don’t biodegrade easily. Throwing contact lenses into toilet is particularly concerning because their size and ________ allow them to slip through filters（过滤器）meant to keep non-biological waste out of wastewater treatment plants.

The study found that the chemical and mechanical processing at these treatment facilities were unable to ________ break down contact lenses, leaving them as part of the treated water. Post-treatment wastewater is typically spread on fields, where contact lenses can make their way into surface water and cause environmental damage.

It may seem like a small thing, but with over 45 million contact ________ in the United States, all that plastic adds up. We are talking about 22 tons of contact lenses being improperly thrown away every year here, unnecessarily adding to the hundreds of thousands of tons of microplastics ________ in our oceans.

So what is the right way to throw away contact lenses?

It turns out that properly dealing with contact lenses is pretty ________. One option is to throw them in the garbage. While this will keep them out of our water ________, it sends them to landfill—which is not really any better. Unfortunately, you can’t just throw your contacts in the recycling bin and call it a day, either. Due to their size and packaging materials, recycling facilities typically cannot ________ contact lens processing, so they go to landfills. In order to actually be recycled, contact lenses need to be ________ at a specialty recycling facility.

This doesn’t mean that all eco-conscious contact-wearers must stick to glasses, though. Fortunately, in an effort to ________ the waste produced by contact lenses and facilitate the recycling process, some eye care companies have started their own recycling ________. Through these programs, individuals can ship their used contacts to TerraCycle (a company that ________ in recycling the hard-to-recycle) for free.

10 . An art program is helping students at some of the lowest performing schools in the United States.

On June 8，much of the world ____ the United Nations World Oceans Day. The idea is to remind people how important the world’s oceans are to all life on Earth, to celebrate their beauty, and to bring attention to the ____ human activity has on the oceans.

This year, the theme is “Our Oceans, Our Future,” with special emphasis on finding solutions to plastic pollution, and ____ marine litter for a healthier ocean and a better future.

The world's oceans ____ nearly three fourths of the Earth's surface, and contain 97 percent of our planet’s water. They produce over half of our oxygen，help regulate our climate, absorb carbon dioxide，and support the greatest ____ of life on our planet.

Nearly half of all species on Earth depend on the oceans for survival, and for many of the rest, including people, the oceans ____ the quality of life.

The oceans are also ____ to the world’s economy, because they are key to transportation and recreation. As over 95 percent of the underwater area remains unexplored, it is nearly a ____ that their depths may hold the cure to many a disease, the ____ to many a problem.

And yet, as much as 40 percent of the world’s oceans are ____ affected by human activities that result in pollution, over-fishing, and loss of coastal habitats. Of particular ____ is plastic garbage. Some of it comes from ships that use our rivers, lakes and seas, and eventually ____ into the ocean. But about 8 million metric tons of plastic waste washes off land into the ocean each year.

Once there, it begins to ____ until it turns into small fragments known as micro-plastics. Plastics are a serious threat, because they degrade very slowly, trap sea creatures, damage habitats like coral reefs, and are ____ by marine animals. Researchers have documented the impacts of plastic on over 650 different marine species—including sea turtles, seals, whales, dolphins，porpoises, seabirds, and fish.

On World Oceans Day, we must remember that the health and safety of our oceans is our collective ____，one that we cannot afford to neglect. Only through good stewardship can we safeguard the health of our oceans, and ensure that the oceans continue to meet the needs of future generations.
