3 . On an autumn afternoon, a remote sheep farm in southern Greenland is quiet. The silence is abruptly broken when dozens of sheep come thundering across the hills overlooking the farm. Walking after them are Lars Nielsen and his 37-year-old son Kunuk Nielsen.

The Nielsen family has owned and run the farm since 1972. Kunuk says the summers now are longer than when he was a child and that drought has become a problem. The fields are not so green as those in the old days. He has to buy hay (草料) from European countries.

The effects of a warming climate are obvious on the land. While he intends to struggle on, his older brother Pilu has chosen a different path.

Pilu, 40, lives in Qaqortoq in the south of Greenland -- a town of about 3,000 people. Ten years ago, he got his helicopter pilot's license and is now part owner of a small company called Sermeq Helicopters. It caters to construction and telecommunication workers and an increasing number of foreign tourists.

Pilu says he loves his family's sheep farm. But he saw that warming temperatures were making remote areas of Greenland more accessible and wanted to look for other opportunities. His company's most popular tours include a visit to Greenland's glaciers.

The warming temperatures are also affecting traditional ways of life, particularly hunting. The sea ice is changing; it's becoming less so that hunting on ice becomes more difficult. When there's no sea ice, it's difficult to use dog sledges (雪橇)，and the whole culture around having dogs and dog sledges and doing traditional hunting on the ice is sort of diminishing.

Besides, many Greenlanders, like Pilu, are leaving the countryside for towns and the capital city Nuuk, where opportunities are greater. A report found that Nuuk's share of Greenland's population grew from 17.2% in 1977 to 29.2% in 2014. If there were enough houses in Nuuk, the share would even be bigger.

1. What problem does Kunuk Nielsen's farm face?

A．Lack of workers.	B．Less food for his sheep.
C．Less space forhissheep.	D．Lack of foreign markets.

2. How do rising temperatures affect Greenland?

B．By making it hard for locals to earn a living.

C．By promoting the development of its tourism.

D．By making more remote areas suitable for living.

3. What does the underlined word “diminishing” probably mean?

A．Occurring.	B．Operating.
C．Adapting.	D．Decreasing

4. Which of the following limits Nuuk's population growth?

A．Housing pressure.	B．Climate change.
C．Weakeconomy.	D．Poor living conditions.

4 . For some people, walking or running outdoors is a great way to work out. What may not be so pleasant is seeing trash all over the ground. Well, some people are doing something about it. They are plogging!

“Plogging” began in Sweden. The name combines the Swedish word “plocka,” which means to pick up, and the word Jogging, which means to run slowly. A Swedish man named Erik, started the movement in 2016. On the World Environment

Day website, Erik says that he moved to Stockholm from a small community in northern Sweden each day he would ride his bike to work. Concerned about the amount of trash and litter he saw each day on his way to work, he took matters into his own hands.

Plogging, by that term, may have officially begun in Sweden. But many people who exercise outdoors have been doing this for years. Take Jeff Horowitz for example. He is a personal trainer in Washington, D.C. He often picks up trash while running outside. He even has turned it into a game; he will try to pick up the trash without stopping. “I didn’t know it was a thing really. This is just my personal ethics (道德标准), where I go for a run and if I happen to see a piece of garbage lying around and it’s within reach — it is a kind of a little test for me to see if I can grab it and throw it in a near trash can without stopping. And that way, I think, it gives me a little exercise and a little focus for my run. And it helps clean up the neighborhood,” he announced.

Today, plogging is an official activity, one that is becoming increasingly popular. Cities around the world now hold logging events, “I would just hope people would think twice before dropping a garbage on the ground. We have containers seems on every block. So, it’s easy to put your garbage in the trash cans. I just think people should think about it a little bit more. I do hope one day there will not be a need for plogging.” said an interviewee.

B．Plogging is an easy way to clean the environment.

C．It doesn’t make any sense to joy without picking up trash.

D．It is better to clean up the neighborhood by plogging.

3. What is the idea that Logging events are meant to promote?

A．Jogging is truly beneficial.	B．Trash cans should be within reach.

5 . Scientists have long known that a crow （乌鸦）native to New Caledonia is able to use tools. The birds use them to remove food from deep holes. Now, American researchers have discovered a second species of crow with the same ability. They reported on their experiments with Alala crows, which are from the Hawaiian Islands.

In the experiment, the researchers placed pieces of food in holes inside the wood. The holes were too deep for the crows to reach with their beaks(鸟喙). But, by using small pieces of wood held in their beaks, Alala crows quickly got the food. They used small objects as tools, sometimes changing them by shortening too-long sticks. They also made tools from plant materials.

“The crows use their beaks as people use thumbs on their hands. Tool use is rare in the animal kingdom. ” said Chritian Rutz of University of St. Andrews. “Current evidence strongly suggests that tool use is part of the species’ natural behavioral pattern(行为模式). These birds had no special training in the study, yet most of them were skilled at handling stick tools. ”

Bird experts claim finding out that the crows use tools is important discovery. “It makes us rethink how to look at the whole tool-use idea now and encourages us to go out and look for things that we may have ignored before. ”

All the Alala crows left in the world live in Hawaii. There were less than 20 Alalas left in the late 1990s when scientists decided to bring them into a protected area. Now, it is reported that there are over 100 birds living there. Scientists plan to release a small number of the birds back into the wild later.

1. What are the findings of American researchers?

A．Alala crows can also use tools.

B．It’s difficult for birds to look for food.

C．New Caledonia is home to some crows.

D．The Hawaiian Islands are full of rare birds.

2. What can we learn from the study?

A．The holes were very big and wide.

B．Alala crows could only use short sticks.

C．Alala crows got the food by working together.

D．Alala crows would deal with tools if necessary.

3. What do Chritian Rutz’s words mean?

A．Using tools comes naturally to Alala crows.

B．Using stick tools is not easy for Alala crows.

C．Alala crows’ beaks look like people’s hands.

D．Alala crows won’t use tools without being trained.

4. What do scientists plan to do with Alala crows?

A．Move all of them out of Hawaii.	B．Increase the population of them.
C．Set some of them free in nature.	D．Build more protected areas for them.

7 . Have you ever been into a cave? If not, please follow us and explore some of the most beautiful caves from around the world!

Marble Caves

Located in the center of Lake General Carrera, the Marble Caves in Chico, Chile, are only accessible by boat. The surrounding crystal clear waters allow visitors to see the rock formations beneath them while the rock ceilings above change color(depending on the writer levels and the season). The best time to visit: during sunrise and sunset, when the sun’s rays light up the cave walls, making it an experience to remember.

Reed Flute Cave

Reed F1ute Cave known as “the Palace of Natural Arts” is located in the northwest of Guilin in southern China.The limestone cave offers a grand fairyland of stalactites(钟乳石), stone pillars, stone curtains, birds, plants and animals in fantastic shapes and colors.

Fingal’s Cave

This incredible sea cave is located on the uninhabited island of Staffa in Scotland. The cave’s size, shape, and naturally—arched(拱形的) roof combine with the waves to create strange sounds that enhance its cathedral—like atmosphere.

The Blue Grotto

The Blue Grotto is the symbol of Capri. It is a sea cave found on the coast of the island and is a well-known spot to all who visit the area. This cave is unique for its brilliant blue light which comes from two sources: the entrance to the cave and a bigger hole beneath the entrance. When viewed from inside the cave, the entrance appears as a brilliant white light just above the waterline, while the underwater hole, which is the larger source of light, provides a blue light.

9 . Far from the land of Antarctica, a huge shelf of ice meets the ocean. At the underside of the shelf there lives a small fish, the Antarctic cod.

For forty years scientists have been curious about that fish. How does it live where most fish would freeze to death? It must have some secret. The Antarctic is not a comfortable place to work and research has been slow. Now it seems we have an answer.

Research was begun by cutting holes in the ice and catching the fish. Scientists studied the fish’s blood and measured its freezing point.

The fish were taken from seawater that had a temperature of -1.88℃ and many tiny pieces of ice floating in it. The blood of the fish did not begin to freeze until its temperature was lowered to -2.05℃. That small difference is enough for the fish to live at the freezing temperature of the ice-salt mixture.

The scientists’ next research job was clear: Find out what in the fish’s blood kept it from freezing. Their search led to some really strange thing made up of a protein never before seen in the blood of a fish. When it was removed, the blood froze at seawater temperature. When it was put back, the blood again had its antifreeze quality and a lowered freezing point.

Study showed that it is an unusual kind of protein. It has many small sugar molecules held in special positions within each big protein molecule. Because of its sugar content, it is called a glycoprotein. So it has come to be called the antifreeze fish glycoprotein. Or AFGP.

1. What is the text mainly about?
