Osedax worms have been found in oceans all over the world. They've only ever been spotted on bones, which makes some scientists think that the bone-eaters are specialized to live in odd ecosystems, such as whale falls. "Those kinds of animals are definitely uniquely adapted to the environment in which you find them, "says marine biologist River Dixon. She is a graduate student at the University of Louisiana at Lafayette.
But as recent experiments show, the bone-eaters may not be picky about what type of bones they devour(吞食). Last year, biologists spotted Osedax worms in the Gulf of Mexico for the first time. And not on whale bones. Dixon was part of a research team that made the discovery. In early 2019, her group put the dead bodies of three alligators(短吻鳄)in water about 2 kilometers deep. Over the next few months, they sent a remote-controlled vehicle a few times to spy on what were essentially "alligator falls". 51 days after the alligators were placed in the seawater, scientists revisited. "The flesh was gone", Dixon says. . "It had been reduced to just the skeleton(骨骼)." And just as at whale falls, it hosted a carpet of bone-eating Osedax worms. These worms were similar to other bone-eaters but represented a never-before observed species. That means the scientists who found them get to name it (although Dixon says they haven't settled on a name yet).
The lab where Dixon works studies food systems in the deep ocean. Algae and plants use photosynthesis(光合作用)to turn sunlight into food. Animals eat those plants and algae to survive. Then larger animals may eat those animals. But sunlight doesn't reach the deep ocean's bottom. So other pathways are essential. These pathways include whale falls and other dead bodies. The scientists wondered how alligator falls fit into a larger food web. To find out, they submerged them.
Studying alligator falls, Dixon says, could help show how life evolved(进化)in the deep sea. It's possible that the creatures found on whale falls and other falls today, Dixon says, evolved from creatures that hundreds of millions of years ago would have devoured plesiosaur (蛇颈龙) falls.
Last summer holiday, Aunt Emily took us to a safari park (野生动物园), not far from Liverpool.
I was very happy to go as I had never been to a safari park before. It's a very interesting park, full of wild animals running freely.
When we got there, we bought our tickets and drove into the park. We were very excited at the thought of going to see the lions. But to get to the lions' place we had to go through the monkeys' land first. And that was an unforgettable experience because they climbed all over the car, ate apples and bananas, and threw all kinds of things at us. They seemed very unfriendly.
Anyway, we went on our way to the lions' place where we had to lock ourselves in the car as we knew lions could be dangerous. A lion came up very close to us. Then it was on the bonnet (车盖). It looked calm but we felt terrified. Aunt Emily, who isn't very brave, started to call for help. The kids started crying. Only my brother, George, stayed cool. I sounded the horn (喇叭) but nobody heard us.
In the end a guard arrived in his car, and the lion just got off our car and started smelling the guard's hand as if nothing was the matter.
Tiny trash factories
Not all waste has to go to waste. Most of the world's 2.22 billion tons of annual trash ends up in landfills or open dump. Veena Sahajwalla, a materials scientist and engineer at the University of New South walks, has created a solution to our massive trash problem: waste microfactories. These little trash processors house a series of machines that recycle waste and transform it into new materials with thermal technology. The new all-in-one approach could leave our current recycling processes in the dust.
Sahajwalla launched the world's first waste microfactory targeting electronic waste in 2018. A second one began recycling plastics in 2019. Now, her lab group is working with university and industry partners to commercialize their patented Microfactoric technology. She says the small scale of the machines will make it easier for them to one day operate on renewable energy, unlike most large manufacturing plants. The approach will also allow cities to recycle waste into new products on location. With a micro-factory, gone are the days of needing separate facilities to collect and store materials, extract elements and produce new products.
Traditionally, recycling plants break down materials for re us c in similar products. It is like melting down plastic to make more plastic things. Her invention evolved this idea by taking materials from an old product and creating something different. "The kids don't look like the parents," she says.
For example, the microfactories can break down old smart phoned and computer monitors and extract silica and carbon, and then combine them into silicon car bide nanowires. This generates a common ceramic material with many industrial uses. Sahajwalla refers to this process as "the fourth R," adding "____" to the common phrase "reduce, reuse, recycle."
In 2019, just 17.4 percent of e-waste was recycled, so the new ability offers a crucial new development in the challenge recycling complex electronic devices. "We can do so much more with materials," says Sahajwala." Traditional recycling has not worked for every recycling challenge." She and her team are already working to install the next waste microfactory in the Australian town of Cootamundra by early 2021, with the goal of expanding around the country over the next few years.
We live in the Internet age when much business is conducted online.

It happened on a rainy Saturday morning last month. My wife Catherine and I were driving along what some people called moose (麋鹿) alley. It was so 1 that there were few cars on the road. 2 , a moose jumped out across our path. I had been driving for years and was 3 in driving. In order to avoid knocking 4 the moose, I made a quick turn to the other lane. Had I not done that, the moose might have been killed, and my wife and I might have got 5 , too. A few seconds later, when I stopped and looked back in my rear view mirror, the moose was getting up and then ran into the bush. Shaken but 6 , we both looked at each other with a surprised expression.
From then on, I often thought about the 7 between humans and wildlife. We know that animal species have appeared and disappeared 8 since life began on the Earth, which is a(n) 9 phenomenon. However, animal species have been 10 at a much faster rate for about a century now 11 human factors such as pollution.
Certain philosophers and scientists keep repeating that if we don't save animals, how we will be able to save ourselves. A better 12 of animals gives us a better understanding of our own species. The 13 to protect animals and nature in general 14 the value of a society. And all animals play roles in nature and have a right to 15 . Therefore, I think we should try our best to save endangered animals, because humans cannot live on the Earth alone.
Despite many laws and national parks protecting tigers, their habitats continue to be destroyed and they are still being hunted. (honest) speaking, tigers are among the most endangered species in the world nowadays. Altogether, there are no more than 5,000 tigers (leave) in the wild. Some think that the tiger is already to the point of (extinct) in the wild. There are many reasons for this, like habitat loss and hunting.
Actually, over the last few decades, a number of steps (take) to help preserve the tiger. The Wildlife Conservation Society (WCS)was set up to protect wildlife and their habitats in early 2000s. Today WCS is carrying out work in 53 nations across the world, protecting a great variety of species from butterflies to tigers. In 2010, WCS started Tigers Forever, aim was to increase the number of tigers in the world 50 percent in the next 10 years. (achieve) their goals, they are working together with not only governments other organizations to protect tigers and other wild species.
Right now the tiger population is increasing steadily under this program in India and in Far East Russia. Thanks to the hard work of WCS, these large cats have a (good) chance of survival in their natural environments than ever, not just in zoos.

An unforgettable travel experience
阅读下面材料，根据其内容和所给段落开头语续写一段，使之构成一篇完整的短文。
As an only child, Nicole Renae often felt lonely in her youth. But that all changed when she turned ten. For her birthday, Renae's grandmother surprised her with an adorable gray puppy named Chloe. From the very start, the two were inseparable. "She was my best friend," Renae says. Every ounce of love Renae gave, the little dog returned tenfold. "She was such a sweet dog," Renae says. "She'd lick your face forever if you didn't stop her."
But when Renae was 14, her father got a new job and he'd be working at home, so the house needed to be completely quiet. Chloe barked a lot so they had no choice to give it up to a humane society. Though they were optimistic that the dog would find a new home with people who loved her, they couldn't know for sure.
In time, Renae got married, and had a child of her own. But her family didn't feel quite complete. Remembering the joy that having a dog had brought her as a kid, Renae wanted her daughter to experience the same. She decided that she would adopt a puppy, and then one day she saw a post on Facebook about a senior dog that needed a new home. The dog in the photograph looked a lot like Chloe — she was even named Chloe. In an instant it was decided: She would adopt this older dog.
注意：1.续写词数应为100左右；2.请按如下格式在答题卡的相应位置作答。
When she met Chloe, Renae found that the dog seemed so familiar.
