When storms come rolling in across the ocean, they struck coastlines with tremendous force. Luckily, for thousands of miles of tropical coastlines, nature has provided a remarkable form of protection: coral reefs.

These colorful wonders are best known for their diversity of life, their plentiful seafood, and their draw to scuba-diving tourists. But they are also astonishingly durable and firm structures, built by tiny animals with calcium carbonate skeletons (碳酸钙骨架), which provide an important service to the coastlines standing behind them — they can absorb up to 97% of wave energy.

A new study estimates that reefs offer protection to up to 5.3 million people and $109 billion in gross domestic product (GDP) per decade. The maps in the study scientists generated are at a much finer resolution (分辨率) than previous analyses, which allows users to view coral reefs with more details and see where reefs provide the highest degree of protection for people, GDP and infrastructure (基础设施). “This level of detail means we can use this information in practical ways, like in the marine spacial planning we do to inform conservation strategies around the world,” says Dr. Spalding, the co-author of the study. More accurate data on where reefs protect people and infrastructure from destructive waves can help improve decision-making about which reefs to protect.

We have already lost half of the world’s reefs, and scientists predict we could lose up to 90% if actions are not taken to protect them. Effective management strategies are vital to supporting reef health and recovery.

Coral reefs are often selected for conservation based on their ecological significance, which may mean they are located in remote places, away from the more direct effects of human pressures like development and pollution. “We are failing ourselves as well as nature if we don’t also consider protecting the reefs that are located closer to humans,” says Spalding. “These are the reefs that protect us and provide for us in abundance. Let’s look after them.”

One night, Pilar was in a deep sleep when she was woken by her cat Inti. Inti was meowing wildly outside Pilar’s bedroom and throwing himself against the closed bedroom door. When Pilar opened her eyes, she saw that her bedroom was filled with smoke. As she escaped her house with Inti in her arms, she saw that a fire was burning in her kitchen. Pilar could easily have lost her life, but Inti would not let that happen. Even though Inti could have escaped the house through a cat door, he wouldn’t leave Pilar.

As amazing as this story is, it is not as uncommon as you may think. Take the example of Charlotte Lee and her horse, Thunder. One summer night, the whole family was asleep with the windows open. It was normally very quiet where they lived. Suddenly, there was a loud noise. Charlotte woke up from her sweet dream, and the noise continued. Then she heard a horse running fast towards the house. The next thing she saw was Thunder standing outside her window, neighing and shaking his head. She knew something was wrong. Charlotte quickly got everyone out of the house before the earthquake hit. Thunder has saved her life.

There are also stories of animals coming to the rescue of humans. One animal known to be a friend of humans is the dolphin. Once, Todd Endris was surfing with his friends when he was attacked by a 13-foot (4-meter) shark. In the middle of the attack, a group of dolphins came to his rescue by forming a protective ring around Todd until he could get safely to the shore. Without the help of the dolphins, there is little chance that Todd could have escaped.

No one is sure why animals have so often come to our rescue. However, it is clear that humans and animals enjoy a close relationship. It is important that we care for them as much as we can.

【小题1】Why did Inti throw himself against the door?
A.He was trying to wake up his owner.
B.He wanted to get out of the room.
C.He felt bored and was playing by himself.
D.He couldn’t find the way out because of smoke.
【小题2】What did Charlotte do before the earthquake?
A.She closed the windows.
B.She was sleeping deeply.
C.She ran to warn her neighbors.
D.She got her horse out of the stable.
【小题3】What do we know about Inti and Thunder?
A.They were shy and quiet.
B.They used to make noise at night.
C.They were brave and smart.
D.They saved their owners several times.
【小题4】Which of the following is probably Todd’s feeling towards the dolphins?
A.Doubtful.B.Grateful.
C.Frightened.D.Bored.

For months, their adventure through China’s south-western Yunnan province had gone almost unnoticed. But last week, when images of a group of 15 Asian elephants walking through a residential(居民的) area appeared on social media, it immediately seized the imagination of the nation, stirring up considerable media interest and questions as to what caused their unusual journey.

The movement was so unusual that authorities sent as many as 360 people with 76 cars and nine drones(无人机) to track it. State TV has spent days following their every footstep. Chinese wildlife authorities have been struggling to understand why the elephants left their natural habitat last year. According to Xinhua, a group of 16 wild elephants began the journey in March 2020 to the north. In November, they arrived in Pu’er in Yunnan, where a female elephant gave birth to a baby, and settled there for five months. They then continued the walk on 16 April. A week later, two left the group, leaving 15 to continue their odyssey.

The appearance of the animals has not been warmly received by residents in Yunnan. Along the way, they have caused much destruction, eating whole fields of corn and ruining farm buildings. State broadcaster CCTV has estimated the damage to be at least 6.8m yuan ($1.07m). Fortunately, no human death has been reported so far.

Chinese experts said there had been other reports of elephants wandering into villages and harming crops in recent years. “Large-scale human engineering developments have changed the ‘islanding’ of elephant habitats,” said Zhang Li, a professor from Beijing Normal University. “The traditional zones between humans and elephants are gradually disappearing, and the chances of elephants’ facing humans naturally increase greatly.”

The wild elephant population in Yunnan is about 300, up from 170 in 1980, but the habitat area has decreased from 2,084 square km in 1976 to less than 500 square km in recent years.

【小题1】What happened to the group of wild elephants in Yunnan?
A.They got trapped while approaching a residential area.
B.They headed north after leaving their natural habitat.
C.They had a newborn baby in March 2020.
D.They split up and three male elephants left.
【小题2】What does the underlined word “odyssey” in paragraph 2 mean?
A.Adventure.B.Break.C.Struggle.D.Victory.
【小题3】How did the local residents feel about the elephants?
A.Excited.B.Confused.C.Embarrassed.D.Annoyed.
【小题4】What can be concluded from the last two paragraphs?
A.Wild elephants got on well with humans in the past.
B.An island will be reserved to protect wild elephants.
C.The number of wild elephants will stay stable.
D.There may be more human-elephant conflicts in the future.

One of the most critical roles forests play is relieving climate change. Trees suck enormous amounts of carbon dioxide out of the air and fix the carbon in their wood and the soil. A recent study found that planting new trees over an area the size of the US could suck away two thirds of all the carbon dioxide discharge that humans have pumped into the atmosphere.

“Without animals, it is harder for forests to absorb carbon, as tree species (种类) important for protecting the climate could be lost without animals", Susanne Winter, a program director said at the WWF.

In Africa, many of the tree species that absorb the most carbon rely on large birds and primates (灵长类动物) to eat their fruits and spread their large seeds, according to the report. Without them, those trees would have difficulty reproducing and forests would lose their best carbon-storing trees.

“Forests are our greatest natural ally in the fight against global warming, ”Winter said.“If we want to hold back the worldwide decline in biodiversity and prevent the climate crisis,s we need to protect the forests and the species living there.

Forests also filter (过滤) water-- as water makes its way to lakes or groundwater reserves, the roots and soil separate it from deposits and pollution that it collects along the way. What' s more, forests regulate the global water cycle, since trees' leaves, branches, and roots store or send out water vapor.

Climate models show that forest-cutting down in Central Africa could lead to a 15% drop in rainfall in the US Midwest, and Amazon deforestation (森林滥伐) could cut Texas rainfall by 25%.

Humans also get food, wood, and medicine from the abundance of plants and animals in forests. Worldwide, 1.6 billion people rely on forests for their livings, according to the United Nations. About 300 million people live in forests, according to WWF.

【小题1】What's the purpose of Paragraph 3?
A.To tell where the large seeds go.
B.To show the tree species in Africa.
C.To draw reader' s attention to Africa.

【小题4】What can be inferred from the passage?
A.Water should be filtered.
B.The more forests, the more rain.
C.Forests should be globally protected.
D.Half the carbon dioxide is sucked away by trees.
