How Saving Wildlife Benefits Humans
It’s no secret that we’ve lost an overwhelming number of species within that last four decades. These species have all but _____ due to overpopulation, deforestation, consumer culture, climate change, animal exploitation, and other harming sources — all brought about by mankind.
One of the first great rules of terrestrial (陆地的) biology is “no species is forever.” _____, this rapid loss of species today is estimated to be between1,000and 10,000 times higher than the natural extinction rate. As increasingly accepted theories have argued, we are now in the midst of the sixth great _____.
The Earth consists of plants, animals, water, land, the atmosphere, and humans. Biodiversity (生物多样性) _____ the health of the planet and has a great impact on all our lives. Reduced biodiversity means a future where food supplies are vulnerable (易受攻击的) to pests and disease, and fresh water is in short supply. If biodiversity _____ impacts our lives in such big ways, then our conservation (环保) efforts don’t just benefit the environment, they benefit us, too.
One convincing benefit that comes from wildlife conservation efforts is that it ensures food _____. Wildlife conservation promotes agricultural biodiversity, which plays an important role in building a secure and healthy food system. When agricultural biodiversity is _____ and land is cleared for agriculture, extensive habitat loss takes place, as well as undocumented loss of species and massive soil erosion (侵蚀).
Another benefit that comes from wildlife conservation is that these _____ protect human health. Conservation International reportsthat “more than 50 percent of modern medicines and more than 90 percent of traditional medicines come from wild plants and animals.” _____, a world that promotes healthy ecosystems and biodiversity provides crucial buffers (缓冲) between disease and humans. A number of studies have _____ reduced diversity among mammal (哺乳动物 ) species and overall decreases in biodiversity to an increase in the transmission ( 传 播 ) of animal-born diseases to humans.
Perhaps the most convincing benefit that comes from wildlife conservation is that it provides us with _____ whether it be economically or socially. Increasing biodiversity and healthy ecosystems improve agricultural productivity, thereby allowing farms to become more _____. Healthy ecosystems that are home to unique species _____ tourists from around the world, which helps the local economy and invites in a new fusion of investment.
Our unsustainable, unconscious, self-interested relationship with the environment has led us into an extremely destructible world. If we do not take action and _____ changing our ways, we are at risk of losing more vital and _____ ecosystems and biodiversity, or at least until the sixth great extinction claims one final species: our own.

The answer to protecting and saving marine(海洋) wildlife can start with cutting back on something Americans use every day—plastic drinking straws. Actor Adrien Grenier, best known for playing Vincent Chase in 2015 movie Entourage, has launched a campaign to reduce the amount of single-use plastic usage in this country in order to protect and save marine wildlife and the environment. Plastic drinking straws are among many single-use plastic products contributing to the shocking loss of marine life, but they’re a great place to start because they’re something Americans are using by the hundreds of millions without any awareness that they’re so damaging.
According to Ecocycle, an international environmental organization, Americans use more than 500 million straws daily, which are enough to fill 127 school buses each day, and they can’t be recycled. They means plastic straws end up in landfills or oceans, where fish and other marine wildlife mistake the small bits for food and swallow them. After seeing a photo of a whale beached on the shore with a belly full of plastic, Grenier felt the inspiration to launch the Lonely Whale Foundation, hoping to inspire and educate others on the challenges facing marine life.
Along with stopping the use of straws, Grenier hopes to educate consumers on the dangers of other single-use plastic items such as grocery bags and water bottles. While many Americans use these plastic products in their daily life, there are more sustainable alternatives that can help protect the environment. Ecocycle recommends the use of straws made from stainless steel, glass, and even bamboo instead of plastic. You can buy a number of these environmentally friendly straws online and in stores.
1.What initially contributed to the start of Grenier’s campaign?
A. Plastic straws in landfills.
B. A picture of a dead whale.
C. The severe damage done to the sea.
D. The disappearance of some species under the sea.
2.What is the primary purpose of the Lonely Whale Foundation?
A. To advocate a green lifestyle.
B. To promote Grenier’s latest movie.
C. To save precious natural resources.
D. To encourage people to protect ocean life.
3.Ecocycle advises people to use straws that are ________.
A. easy to recycle
B. convenient to use
C. special to marine life
D. harmless to the environment

Spoiled for choice? That's likely how you'll feel after a mere day in Athens. The secret is in not trying to do everything. Instead, take in a couple of the tourist highlights and then get a feel for this attractive capital.
An ancient sight
The Acropolis (卫城) always comes out at the top of the list of things to see in Athens. The most famous of the western world's ancient sights continue to impress tourists as they climb the marble steps and stand before the graceful Parthenon. Views from up here are amazing.
A slow wander
Plaka is the city's oldest neighborhood, resting on the slopes of the Acropolis with cafs and fascinating architecture. The streets are perfect for getting lost in, giving wanderers the chance to discover cafs and bars where they can down some strong coffee among locals. Plaka is at its best in the early evening. Acropolis House Pension is a preserved 19thcentury house that gives guests a glimpse into a Greek home.
A market scene
Varvakios Agora is Athens' central market. Locals come here to shop and look for everything needed in a Greek kitchen — from olive oil to meat. This is a look at local life as well as a window into Greek cuisine. The meat market is also home to some of the city's best pubs, feeding traditional food to crowds of customers from all walks of society.
A splash of nightlife
Athenian nights are filled with music, dancing and dining. Perivoli Tou Ouranou is a club with a strong atmosphere. Filled with the sounds of violins and guitars pelting out traditional blueslike music, it's sad but also beautiful and lively.

Bowhead whales (弓头鲸) can live 200 years or longer. How they do it is no longer among the secrets of the deep. Scientists have mapped the genetic code of this long-lived whale species. The international effort found unusual features in the Arctic whale’s genes. Those features likely protect the species against cancer and other problems related to old age.
“We hope to learn what is the secret for living longer, healthier lives,” says João Pedro de Magalhães. He is a gerontologist (a scientist who studies old age) at the University of Liverpool in England. He also is co-author of the study that appeared January 6 in Cell Reports. His team hopes, he says, that its new findings might one day be used “to improve human health and preserve human life.”
No other mammal is known to live as long as the bowhead. Scientists have shown that some of these whales have lived well beyond 100—including one that survived to 211. For perspective, if he were still alive, Abraham Lincoln would be turning just 206 this year. De Magalhães’ team wanted to understand how the bowhead can live so long. To study this, the experts analyzed the animal’s complete set of genetic instructions, called its genome (基因组). Those instructions are coded in the animal’s DNA. The team also compared the whale’s genome to those of people, mice and cows.
The scientists discovered differences, including mutations (突变), in the whale’s genes. Those changes are linked to cancer, aging and cell growth. The results suggest that the whales are better than humans at repairing their DNA. That’s important because damaged or flawed DNA can lead to diseases, including some cancers.
Bowheads also are better at keeping abnormally dividing cells in check. Together, the changes appear to allow bowhead whales to live longer without developing age-related diseases such as cancer, says de Magalhães.
1.What do we learn about bowhead whales?
A.Their average life is 100. B.They are the longest-lived animals.
C.They don’t have aging problems. D.They live in the Arctic Ocean.
2.Why did scientists map the genetic code of bowhead whales?
A.To discover the secret of long life.
B.To find out a cure for cancer.
C.To prevent age-related diseases.
D.To lengthen human life.
3.Why does the author mention Abraham Lincoln?
A.To remind us of the time he lived.
B.To show the long life of the bowhead.
C.To compare him with the bowhead.
D.To express people’s respect for him.
4.What allows the bowhead to live a longer and healthier life?
A.Good DNA repair system. B.Gene mutation.
C.Cell division. D.Perfect living environment.
