四、阅读理解。（本题共15小题，每小题2分，共30分）
In a coastal city of Brazil, there is a special fishing team. It is made up of human fishers and dolphins! They work together to catch the same fish—the mullet (鲻鱼).
Mauricio Cantor from Oregon State University, the US, studied this. As he told Science News Explores, this partnership started more than a century ago.
“The dolphins are really good at finding fish in the murky (浑浊的) water and driving them to the coast,” Cantor said. “The fishermen are really good at catching the fish with their nets.” Once the fish are caught in the nets, dolphins can move in and get some for themselves.
Cantor’s study described how fishermen and dolphins give cues to each other during fishing. After dolphins find fish, they drive fish to the coast. Then they arch (拱起) their backs in front of the fishermen to tell them to cast nets (撒网). Fishermen will then cast the nets right away, or they may lose the best chance. “Fishermen need to be well-trained to understand the cues from dolphins,” said Cantor.
The study found that fishermen are 17 times more likely to catch fish by working with dolphins. At the same time, the helpful dolphins have 13 percent higher survival rates (存活率) than other dolphins.
“Human-animal partnerships have been hard to see throughout history. But they give us an idea of how positive our human interactions (互动) can be with nature,” Cantor said.
46．What does “this” in Paragraph 2 refer to
A．A city. B．A study. C．A university. D．A fishing team.
47．What is the right order of dolphins and fishermen working together according to the study
①dolphins arch their backs ②fishermen cast nets ③dolphins move in and get fish
④dolphins find fish in the water ⑤dolphins drive fish to the coast
A．④③②⑤① B．⑤①③②④ C．④⑤①②③ D．⑤②①④③
48．In Paragraph 5, the author mainly wants to show this partnership _________.
A．should be improved and changed B．must last for a long time in history
C．might result in a win-win situation D．could be in danger and end up soon
49．What’s the writer’s real purpose in the last paragraph
A．To introduce how to cooperate with animals.
B．To tell us that humans can cooperate with animals positively.
C．To question the partnerships between humans and nature.
D．To explain the reasons why human-animal partnerships are popular.
50．What would be the best title for the passage
A．Train Hard to Win B．Team Up to Fish
C．Get Close to Nature D．Say No to Animals
At the age of 16, Julia Butterfly Hill left school and worked at a restaurant. For many years, she was only interested in making money. Then one day she had a serious car accident which changed her life. “I had a terrible car accident. It took me 10 months to recover from the accident. During that time, I realized I wanted to find a more meaningful reason for being here on earth,” said Hill.
As soon as Hill recovered, she travelled to California. One day she found a company wanted to cut down part of a forest. In the forest there were lots of redwood trees. One of the trees was more than 1, 000 years old.
Hill learnt that a group was trying to save the redwood forest from the company. They decided to find someone to live in a redwood tree and hoped this would stop the company from cutting the trees down. Hill volunteered.
Hill lived in the tree for over two years without ever going down. It was cold and wet in the redwood tree. There were even very serious winter storms while Hill was in the tree.
Finally the company decided to protect the tree
Hill lived in. They agreed never to cut down the big redwood tree or the trees around it. When Hill put her feet on the earth, she began to cry. But she continued to do other things to protect the environment.

Once there were many thousands of Gourma Desert (沙漠) elephants in Mali, a country in West Africa. Now there are fewer than four hundred.
Why did the number of the elephants drop so quickly On the one hand, the elephants’ main lake, their only water source (来源) dried up. On the other hand, the land which the elephants lived on was overused by humans.
To protect the elephants’ living environment, the Mali Elephant Project (MEP) was started in 2007. MEP met with local people and helped them make rules of using land and water. As a result, the situation became better and there was more food, forest and grassland.
However, from 2012 to 2016, poaching and illegal (非法的) trade in the elephants increased rapidly. Eighty-three elephants were lost in 2015 alone, and another fifty-one elephants were killed in 2016. “If this situation goes on, all the Gourma elephants will be killed by 2025.” said a member of MEP.
Luckily, the voice of MEP was heard. More organizations have joined together to educate the local people that trading elephants is against the law. Elephant poaching has dropped to a very low level. The local people have learned to live peacefully with the elephants, one of the wildlife treasures in the world.
56．How many reasons are mentioned for the drop in the number of the elephants
A．One. B．Two. C．Three. D．Four.
57．Why was MEP started
A．To stop the main lake from drying up.
B．To make rules of using land and water.
C．To protect the elephants’ living environment.
D．To stop humans from overusing the land which the elephants lived on.
58．What does the underlined word “poaching” mean in Chinese
A．繁殖 B．偷猎 C．保护 D．喂养
59．What can we infer (推断)from paragraph 4
A．Trading elephants is allowed.
B．The number of elephants has increased.
C．There was little elephant poaching from 2012 to 2016.
D．The situation will be worse unless humans stop killing elephants.
60．What’s the passage mainly about
A．The education of the local people.
B．The work of Mali Elephant project.
C．The situation of Gourma Desert elephants.
D．The reason why the number of the elephants dropped.

Hello, I’m Frank, a nature lover. Last Saturday, I visited Nature World with my friends. We saw interesting plants and animals from different places of the world. In Nature World, animals are not kept in cages, so they are free to walk around. There is a water plant park in Nature World. It has over 500 types of water plants. In the afternoon, we watched a show. During the show, we saw many interesting animals, such as ducks, bees, monkeys and so on. But I thought a small parrot was the most special among them because it could do Maths problems! All of us enjoyed ourselves in Nature World and we look forward to our next visit to it!
