If social distancing is driving you a little crazy， here are four worlds most beautiful natural pools for you to get relaxed.

Devils Pool

Victoria Falls in southeastern Africa measures 108 metres tall and more than 1，676 metres wide. But for some brave people， the top of the Falls， known as Devils Pool， is just another swimming hole. With water levels at their lowest from September to December， large numbers of swimmers take adventure into the pool.

Barton Springs Pool

Barton Springs Pool in Austin， US， covers three acres and maintains a temperature of about 20 degrees all year round. Admission to the 5-metre deep pool ranges from mid-March until the end of September. For local residents （居民）， the cost is $3 for adults and $1 for kids under 8 （non-residents pay $8 for adults and $3 for kids under 8）.

Bondi Icebergs Public Pool

A 15-minute drive from Sydneys CBD sits the Bondi Baths at Bondi Icebergs. The historic 50-metre public saltwater pool has been around for more than a century and features a small beach， where you can enjoy the sunshine. The entrance cost （$7 for adults; $5 for kids） isnt much considering the million-dollar view.

Dudu Blue Lagoon

Want to float （漂浮） in a quiet 30-metre-deep freshwater pool？ Then check out Dudu Blue Lagoon on the northeastern coast of the Dominican Republic. The Lagoon also features underwater caves， making it a popular diving destination.

When leaving school， I was pleased that my exam results meant that I could study engineering at university. But I also wanted to travel before starting my course. A friend of mine told me about the Schools Exploring Society， an organization which helps students take a gap year （a year between leaving school and going to college）. It has three foreign journeys a year， taking 16—20-year-olds on science and nature trips. I love being outdoors， and a mountaineering trip to Alaska was on offer. So I signed up immediately.

There was one problem， though. I had to raise a large amount of money for the trip. It was a big task， but I managed to make it. I washed cars， worked in a cafe and also sold off some of my old books， clothes and CDs. Then， just before starting out， I started worrying. Can I do this？ Am I fit enough？ What if I see a bear？

Seventy of us traveled to Alaska. The first two days after arrival were spent in a school hall preparing our equipment （裝备） and five tons of food. Then we left for the beautiful Talkeetna Mountain. On the trip we dug paths and recognized plant species （物种）. Then we climbed a mountain that was over 6，000 feet high. It was tiring but exciting.

Looking back， a gap year was so right for me. I learned a lot about accepting other people for what they are. We had to help each other and it made me less selfish. My gap year has also made me more able to concentrate. Now， whenever Im worried about anything， I think I did Alaska—I can do this！

24. What can we learn about the author from Paragraph 1？

A. He hadnt taken foreign trips before.                B. He made the trip with his friends.

C. He wasnt satisfied with his exam results.        D. He was to study engineering at college.

25. What problem did the author have？

A. He wasnt strong.                                              B. He couldnt afford the trip.

C. He had no outdoor experience.                         D. He had little time to prepare for the trip.

26. What do we know about the authors gap year？

A. It was well worth it.                                          B. It got him interested in plants.

C. It made him fall behind others in study.           D. It helped him know more about himself.

27. What might be the authors purpose in writing the text？

A. To explain how to prepare for trips.                  B. To advise on how to spend a gap year.

C. To share his experience in the gap year.            D. To encourage students to go on a trip.

Australian magpies （喜鵲） are common in Australia， loved and feared in equal measure. The fear arises from the fact that nesting females attack animals—including， or perhaps especially， humans—often drawing blood. The love comes from the fact that they are simply everywhere， easy to recognize， and own a voice that has come to symbolize the sound of nature.

And also， they seem rather clever. Now， research by zoologists at the University of Western Australia hascorroboratedthis—but their levels of intelligence are dependent on the size of the group they belong to.

To get the result， the Australian scientists examined 56 birds from 14 groups of wild magpies living in the suburbs of Western Australias capital city， Perth. The groups ranged between 3 and 12 individuals. Each magpie—tested separately to avoid the risk of it getting help from its mates—was put through four tasks that tested its cognitive （认知的） abilities. These included finding food hidden in a transparent container， finding food hidden in differently colored containers， and a memory test involving finding hidden food. Adult and young birds were tested repeatedly and the results were clear. The birds that lived in larger groups were quicker to master the tasks than those that lived in smaller ones. The difference between intelligent big group members and less intelligent little group members appeared very early in the birds lives.

In a paper published in the journalNature， lead author Benjamin Ashton and his colleagues report that birds living in large groups “show increased cognitive performance”. Moreover， this “general intelligence factor” is strongly linked to reproductive （生殖的） success in females.

Ashton suggests that the findings show the development of intelligence is influenced by pressures present in a complex social group. “Our results suggest that the social environment plays a key role in the development of cognition，” he says.

28. What word best describes Australians feelings about Australian magpies？

A. Frightened.                B. Pleased.                      C. Mixed.                        D. Worried.

29. What does the underlined word “corroborated” in Paragraph 2 mean？

A. Improved.                  B. Proved.                       C. Organized.                 D. Doubted.

30. What can we learn about the magpies in the research？

A. They were put in containers.                             B. They were studied individually.

C. They were allowed to seek help.                       D. They stayed in groups.

31. What can be the best title for the text？

A. Magpies Seem to Be Good Social Birds

B. Magpies in Small Groups Often Perform Better

C. Large-group Living Increases Magpies Intelligence

D. Cognitive Levels Affect Magpies Reproductive Success

D

Unlike thousands of tourists who hike in Yellowstone National Park to admire its natural landscape and hot springs every year， Abdelrhman Mohamed was traveling with a team of scientists to hunt for life within the hot springs.

After several hours of hiking in the Heart Lake Geyser Basin area， the team found four unpolluted pools of hot water. They carefully left a few electrodes （电极） placed into the land next to the water， hoping to attract little-known creatures out of hiding—bacteria （细菌） that can “eat and breathe” electricity.

After 32 days， the team returned to the hot springs to collect the electrodes. Working with other scientists， Mohamed had a look at the electrodes and found that they had succeeded in catching their small game： heat-loving bacteria that “breathe” electricity through the hard surface of the electrodes. These tiny creatures are not only of research interest， they may also hold a key to solving some of the biggest challenges facing humans.

As a means of fighting environmental pollution and creating more energy sources， such bacteria can “eat” pollution by changing deadly pollutants into less harmful matter and producing electricity in the process. “As these bacteria pass their electrons （電子） into metals or other hard surfaces， they can produce a stream of electricity that can be used for low power applications，” said Haluk Beyenal， a famous university professor of chemistry.

Though the researchers did not detail exactly how they would be continuing their work with the bacteria， it will hopefully lead to an exciting new tool for fighting climate change and pollution in the near future.

32. Why did the scientists hike in Yellowstone National Park？

A. To enjoy its good view.                                     B. To look for fresh water.

C. To find the cause of pollution.                          D. To search for special bacteria.

33. What does Paragraph 2 mainly tell us about the research？

A. Its purpose.                B. Its finding.                 C. Its process.                 D. Its significance.

34. How do the bacteria “eat” pollution according to the research？

A. By creating more energy sources.

B. By stopping the pollutants producing electricity.

C. By breaking down harmful matter with electricity.

D. By producing electricity to take in pollutants.

35. What is the authors attitude towards this research？

A. Doubtful.                   B. Anxious.                     C. Positive.                     D. Negative.

39 . If you ask my mom， she will tell you that my most precious toy while growing up was my toy tiger. I first learned about the beauty of tigers as a child while watching animal documentaries. As a young animal lover， I felt so sad that they were an endangered species and I wanted to protect them. I hope that more people can learn about tigers. 40 .
