During the World Elephant Day on Thursday, Chinese and foreign experts gathered in one online forum(论坛)     1     ( discuss) ways to protect elephants better based on the migration(迁徙) of 15 wild elephants in Southwest China's Yunnan Province. This shows how Chinese people care about the    2     ( protect) of these giant friends.

The 15 wild Asian elephants among    3     one male turned back in July finally returned to their habitat after touring for 17 months in Yunnan Province. The case was taken by the experts as a    4     ( success) example on how to protect and guide the migration of wild elephants.

Zhou Jinfeng, Secretary of the China Biodiversity Conservation and Green Development Foundation, mentioned an idea which focused    5     helping wild animals survive by     6     (reduce) the harm to nature and wildlife in our daily lives.

Zhang Chenglin, Deputy Director of the Beijing Zoo，who introduced some measures taken by Chinese zoos to take good care of elephants,     7     (say) that there were around 150 elephants living in zo0s around China.

“    8     ( human) and animals share nature. To protect elephants     9     (be) to protect our planet. Hope we can work with other countries to protect wild animals."     10     woman wrote on Sina Weibo on the World Elephant Day.

2 . Ice Ages

Have you ever heard the phrase “ice age”? It refers to a long period of time when glaciers and ice sheets cover large parts of the Earth. We are actually living in an ice age right now! This ice age began about 2.5 million years ago. Today, large areas of ice cover regions of Antarctica, the Arctic, and Greenland.

The climate changes multiple times during an ice age. It switches between glacial periods and interglacial periods. During glacial periods of an ice age, temperatures are much colder than they are today. Ice sheets and glaciers expand, covering more of the planet. These periods can last tens of thousands of years. The last glacial period started about 120,000 years ago and ended about 11,500 years ago. During interglacial periods of an ice age, the average global temperature increases. Ice sheets and glaciers get smaller. The climate is warmer and wetter than it is during glacial periods. We are currently living in an interglacial period. It started about 11,500 years age—when the last glacial period ended.

Scientists don’t completely understand what causes ice ages. But they do believe that one important factor is the amount of light Earth receives from the sun. When the northern part of the world receives less sunlight, temperatures drop—it gets colder, and more water freezes into ice. This can lead to the start of an ice age. When the northern part of the world receives more sunlight, temperatures rise—it gets warmer and ice sheets melt. Consequently, an ice age ends. However, there are other factors, too, including changes in the water flow of our oceans. Scientists are working to learn more about how different factors may cause an ice age to begin and end.

The current ice age we’re in is not the first the Earth has experienced. At least five major ice ages have occurred throughout Earth’s history.

3 . When the dog Abby disappeared in Dothan, Alabama, all she left behind was her collar(项圈)and an empty tie-out line. June Rountree and her husband searched the neighborhood door to door for their missing 4-year-old black-and-white fur baby to no avail. Three weeks passed and there was no sign of Abby, then something unexpected happened.

June was working on the weekend at the Walmart register when she heard a lot of noise. Somehow, a dog had gotten loose in the store and was cleverly dodging(避开)the would-be shoppers and staff as she rushed through various departments.

“I was like,‘What in the world is happening?’” customer service associate Danielle Robinette said. When the dog arrived at June’s post,register No. 6, it was clear that she wasn’t checking out,but she was checking in. June could hardly believe it. The dashing dog was her long-absent Abby. “I called her name and she came to me,” Rountree said. “I bent over and hugged her. I completely lost it then. I couldn’t speak. I was in complete shock and just couldn’t believe it. ”

No one is sure where Abby was for the three weeks, but for a dog that had been on its own three weeks she was in pretty good shape. The Rountrees believe someone must have been feeding her even if they were unable to catch her, and they’re truly grateful for that.

Someone guesses that since June had been with Abby in the Walmart parking lot a few times, the dog might have recognized the location when she happened upon it in her travels. While we’re not sure where Walmart generally stocks(存货)happy reunions, we think it’s safe to say when Abby left the store to go home with her mom, she was one satisfied customer.

D．June was so excited that she was almost out of control.

3. What probably happened to Abby when she got lost?

A．She was caught by someone.

B．She was adopted by a new owner.

C．She went through very hard times.

D．She was fed by warm-hearted people.

4 . The North Star, also known as Polaris, is often used by campers to help them find their way when they get lost.     1     You can use them to find the North Star and help you if you lose your direction, or just find the North Star for fun if you’re into star gazing.

    2     You can use the Big Dipper(北斗七星)to find the Little Dipper. The Little Dipper is the constellation(星座)that contains the North Star. The tip of the Little Dipper’s handle is the North Star. If you’re able to locate the Little Dipper, you can easily spot the North Star.

Locate the North Star with your smart phone. There are many smart phone applications that work something like a telescope. You allow the phone to find your location, and then point your phone to the sky. The phone acts as interactive map, identifying stars and constellations for you.     3    

Buy a star atlas(星图). If the idea of carrying your phone around while stargazing kills the fun for you, consider buying a star atlas instead. You should also always take an atlas with you when hiking in case your phone battery dies.     4     A star atlas is a book that breaks down the night sky by the region and time of year. You can use it to locate the North Star on any given night.

    5     You can use desktop applications for your computer to know how the sky will look on a given night. These devices can help you plan ahead. You’ll go outside with a rough idea of where you can expect to find the North Star.

A．Plan ahead with your computer.

B．Find the direction north with two sticks.

C．It is very helpful and can be used on any night.

D．This can prevent you from locating the North Star.

E．Here are some ways to help you find the North Star.

F．Rely on constellations in the night sky to find the North Star.

G．Some applications can also assist you to see stars more easily.

5 . Technology is likely to play a big part in reaching its climate goals in the future.

Fusion is the process that fires the sun. But some experts say it could someday power our homes. Fusion happens when the nuclei (核) of two atoms are subjected to extreme heat. This leads to the formation of a new larger atom and large amounts of energy. One problem is the process itself requires a large amount of energy. Developers of the technology haven’t yet performed a fusion reaction that releases more energy than it requires. In addition, running an electric power plant of fusion would require the resulting heat to be contained in an economical way.

Advanced nuclear plants would be smaller than today’s massive nuclear reactors. Experts say they could be used in rural areas and could take over for wind and solar power when the sun goes down or the wind dies. But advanced nuclear reactors are difficult and costly to build. Critics say they would also create more waste. And they would run on uranium (铀), which could make some advanced reactors more appealing to militants (激进分子) seeking materials to make weapons.

Currently, there are 15 direct air capture plants operating worldwide, getting CO directly from the air and puts the gas underground. The costs are currently high. But supporters say those costs will fall as the technology improves. They also say tax breaks for businesses could help the technology. But critics say offering large credits could actually lead to more plants continuing to burn fossil fuels.

Hydrogen (氢) can be mixed with natural gas to make a cleaner-burning fuel. This could power a fuel cell vehicle. Such a vehicle would release environmentally friendly water vapors.

So-called clean hydrogen can be produced using energy methods such as wind and solar. But those methods are more costly than “grey hydrogen”, which is made with fossil fuels. Geothermal power plants capture heat up to 370 degrees Celsius far below the earth’s surface. The heat creates steam that can turn turbines (涡轮机) to produce electricity. But the technology would need to greatly expand to become a major alternative to fossil fuels.

1. How does the author develop the passage？

A．By analyzing the cost.

B．By introducing the values.

C．By weighing the positive and negative.

D．By following the order of great importance.

C．Advanced Nuclear.	D．Fusion and Hydrogen.

4. What is the best title for the text？

A．New Issues Facing Climate Goals

B．Develop New Energy According to Local Conditions

C．What Are the Future Development Goals of Clean Energy？

D．Which Technologies Could Help the World Reach Its Climate Goals？

6 . The general understanding of slow fashion is that it is sustainable fashion with a slightly different focus-speed. In 2007, when author Kate Fletcher coined the term "slow fashion", she called on consumers, designers and brands to slow down and care about quality.

Natural clothing materials and low-impact manufacturing are large parts of the sustainable fashion movement. This movement has invited a closer look into what sustainability looks like and how a change in thinking and practices could influence the fashion industry. Slow fashion is considered to be a continuation of sustainable fashion. Today, it is distinguished by quality, locally manufactured clothing, producing clothes on a smaller scale and with slower production times. Mindfulness is paid to workers, the environment, and cultural connections.

Slow fashion was a reaction to the rapid development of the fast fashion industry, which focuses on cheap, stylish, mass-produced clothes that have a huge impact on the environment. People had begun to notice the instability of the fast fashion model — from the employment of workers to pollution. However, fashion isn't always like this, and slow fashion aims to take us back to where it began, even before the Industrial Revolution.

When Kate first described slow fashion, she wanted it to focus on quality instead of quantity, in addition to the environmental ideals that were associated with sustainable fashion. Though Kate presented slow fashion as an opportunity to create an effective relationship between designer, production and consumer, it has developed over time to function even more. No longer is slow fashion only a theory on connection and better products; now, it includes consumer lifestyles and ethical production.

As consumers learn more about the troublesome practices within the fashion industry, the circles of sustainability are growing closer. Social media has only helped slow fashion brands reach more consumers. Adopting a slow-fashion way of living may seem frightening if consumers are new to the movement; however, it doesn't have to be difficult.

1. Why does Kate Fletcher initially put forward slow fashion?

A．To better the lifestyle of the workers.

B．To care more about quantity.

C．To emphasize the environmental influence of the fashion industry.

D．To introduce the science of choosing clothing materials.

2. What is the disadvantage of the fast fashion industry?

A．It produces clothes of low quality.	B．It encourages producers to earn the most profit.
C．It has a lot of unstable influences on society.	D．It changes the basic function of the fashion industry.

3. What is the author's attitude towards slow fashion?

A．Favorable.

B．Doubtful.

C．Indifferent.

D．Negative.

4. What is the best title of this text?

A．Future of the fast fashion industry.	B．Involvement in the slow fashion.
C．Reduction of clothing production.	D．Common practice in slow fashion.

7 . Every winter, huge crowds come to the parking lots of big box stores. Not crazy shoppers... but crows (乌鸦)

“Sometimes there’re 4,010,00 even 20,000 birds,” says Andrea Townsend, a behavioral ecologist at Hamilton College.” They’re really conspicuous. What they like are urban areas, so you’ll see them in trees, on rooftops, certainly, in well-lit parking lots. They’re their favorite places.”

Crows are known as “partial migrants (候鸟)”. Every year, some members of the population migrate between breeding (繁殖) grounds and overwintering grounds. But others just stay put. So Townsend and her colleagues wanted to know if that urge to migrate was something individual crows can turn on and off. With no previous studies to refer to, they caught 18 crows from overwintering spots to find out. They fitted the birds with little backpack satellite devices after collecting blood and feather samples, keeping recording where they went during winter for years.

Overall, three quarters of the birds migrated, an average of 300 miles. And more importantly, if they migrated once, they did it every year—suggesting traveling is not a habit they switch on and off. The researchers also found migrating crows returned faithfully to the same breeding grounds every year—but were more flexible on where to overwinter, which could be a good thing.

“Birds with flexible strategies can change their behavior when the environment changes, while other birds are more locked into their overwintering sites. They may not be able to adjust so quickly or easily to changing environmental conditions.” Townsend also wanted to know how migration is connected with their mental ability and whether it’s a mental trade-off for the birds—since migrants have to remember all location data.

“Maybe they’re not as good at solving problems as a resident bird that doesn’t have to invest so much in that long-term memory.” Then again, with all that time on the wing, migrants simply may not have as much free time to think hard about problems.

1. What does the underlined word “conspicuous” in paragraph 2 mean?

A．Dangerous.

B．Smart.

C．Annoying.

D．Noticeable.

2. How did the researchers get their finding?

A．By analyzing previous research.	B．By tracking some crows’ movements.
C．By studying crows in urban areas.	D．By comparing different migrating crows.

3. What does paragraph 4 focus on?

A．Crows’ migratory habits.	B．Reasons for crows migrating.
C．Crows’ behavioral changes.	D．Ways of crows overwintering.

4. What might Townsend study next?

A．Problem-solving skill and memory of crows.	B．Impact of the changing environment on crows.
C．Relation between crows’ migration and mind.	D．Differences between migrants and resident birds.

9 . Seventy-year-old Tububatu and his wife live in a village on the edge of Badain Jaran China’s third-largest desert. Since their retirement, they’ve been spending every day fighting the advancement of the desert with the help of plant-life. Others had tried fighting the desert and failed, but they just wanted to know if they could make a difference.

Relying only on their pensions, the retired couple have been slowly and steadily growing their little desert forest. They started out by planting just 50 trees, but kept doubling their efforts to the point where they now plant thousands of trees a year. Even though they mostly plant drought-resistant (抗旱的) species, they still water them at least once a day to make sure they grow better. Their small desert forest now covers over 266 hectares (公顷) and numbers tens of thousands of trees.

The couple stay behind in their village, nearly 100 kilometers away from the nearest town, despite their children’s efforts to get them to move with them to a more comfortable home. They’ve been made fun of by other villagers who believed their efforts to fight the desert were sure to fail, but they haven’t let that prevent them making their efforts. They may very well fail, but at least they’ve given it their all.

Over the last 19 years, the couple have planted over 266 hectares of desert and have no plan of stopping anytime soon. China Daily reports that Tububatu and his wife have so far planted over 70,000 trees and spent more than 1 million yuan of their savings in the process. The bad conditions have caused a lot of damage to their health. They look older than their age, and they both have been battling serious health conditions, but they refuse to abandon their battle against the desert.
