Imagine a world without insects. It might sound good at first without creepy-crawly bugs and annoying flies in your apartment. However, the results would be harmful.

The number of insects has dropped by more than half in the past decades, according to British biologist Dave Goulson, author of Silent Earth: Averting the Insect Apocalypse. As insects make up most of the known species on this planet, this data is not good news.

Insects are indeed on the path to dying out, according to the first global scientific review of insect population decrease, which was published in the journal Biological Conservation in January 2019. The researchers say intensive agriculture has been the main cause of the decrease. Pesticides(杀虫剂), in particular, destroy insect habitats. Urbanization and climate change are also significant reasons. “Unless we convert our ways of producing food, insects will go down the path of dying out in a few decades.”

What would happen to Earth without insects? It’s almost impossible to predict, but the soil healthy and much more. Without insects, many animals would have nothing to eat, and the predators(捕食者) of those animals would go hungry ns well. The ecosystem(生态系统)would be thrown off balance.

“If insect species losses cannot be stopped, this will have harmful effects for both the planet’s ecosystems and for the survival of mankind, said Sanchez-Bayo. once of the authors of the review. The first step to stop this process is “to build a society that values the natural world, both for what it does for us and for its own sake”, Sanchez-Bayo suggests. “The obvious place to start is with our children, encouraging environmental awareness from an early age.”

1. What is people’s general impression of insects?
A.Very interesting.B.Quite unpleasant.
C.Extremely helpful.D.Unexpectedly harmful.
2. What does the underlined word in paragraph 3 probably mean?
A.Drop.B.Change.C.Expand.D.Simplify.
3. Why are insects so important to Earth according to this article?
A.Insects keep the earth ecosystem.
B.Insects ensure the earth’s diversity.
C.Insects make the soil dry and healthy.
D.Insects help slow down climate change.
4. What can we do to stop insect species losses according to Sanchez-Bayo?
A.Use nature in a gentle way.

【推荐1】The elephant was lying heavily on its side, fast asleep. A few dogs started barking at it. The elephant woke up in a terrible anger: it ran after the dogs into the village where they ran for safety.

That didn't stop the elephant. It destroyed a dozen houses and injured several people. The villagers were scared and angry. Then someone suggested calling Parbati, the elephant princess.

Parbati Barua's father was a hunter of tigers and an elephant tamer. He taught Parbati to ride an elephant before she could even walk. He also taught her the dangerous art of the elephant round-up—how to catch wild elephants. Parbati hasn't always lived in the jungle. After a happy childhood hunting with her father, she was sent to boarding school in the city. But Parbati never got used to being there and many years later she went back to her old life. “Life in the city is too dull. Catching elephants is an adventure and the excitement lasts for days after the chase,” she says.

But Parbati doesn't catch elephants just for fun. “My work,” she says, “is to rescue man from the elephants, and to keep the elephants safe from man.” And this is exactly what Parbati has been doing for many years. Increasingly, the Indian elephant is angry: for many years, illegal hunters have attacked it and its home in the jungle has been reduced to small pieces of land. It is now fighting back. Whenever wild elephants enter a tea garden or a village, Parbati is called to guide the animals back to the jungle before they can kill.

The work of an elephant tamer also involves love and devotion. A good elephant tamer will spend hours a day singing love songs to a newly—caught elephant. “Eventually they grow to love their tamers and never forget them. They are also more loyal than humans.” she said, as she climbed up one of her elephants and sat on the giant, happy animal. An elephant princess indeed!

1. For Parbati, catching elephants is mainly to ______.
A.get long lasting excitementB.keep both man and elephants safe
C.send them back to the jungleD.make the angry elephants tame
2. Before Parbati studied in a boarding school, ______.
A.she spent her time hunting with her father
B.she learned how to sing love songs after class
C.she was taught how to hunt tigers in the woods
D.she had already been called an elephant princess
3. Why are Indian elephants beginning to fight back?
A.Because illegal hunters catch them and kill them
B.Because they are caught and sent for heavy work
C.Because they are attacked and their land gets limited
D.Because dogs usually bark at them and interrupt them
4. The elephant story in the beginning shows that in India ______.
A.dogs are often as powerful as elephants
B.people easily fall victims to elephants' attacks
C.elephant tamers are becoming fewer and fewer
D.the man-elephant relationship is getting much worse

文章大意:本文是一篇记叙文。主要讲述了一名护林员帮助狗主人将过热的狗送往兽医院的故事。

【推荐2】The temperature was rising to 90 degrees on Tuesday in the hills of the Delaware Water Gap National Recreational Area, when Lexie Daniel and her friends saw a heroic act of kindness to save a dog’s life.

Lexie and her fellow hikers met a man whose dog was seriously overheated. Even though they donated (捐赠) their water, they were afraid it wouldn’t be enough to save the pup, after seeing how much the dog was already struggling.

“The owner brought along a huge jug, but no water seemed to be helping,” Lexie told GNN.

Too tired to carry the dog himself, the loving owner called the park rangers as soon as possible. Supervisory Park Ranger Kris Salapek soon found them on the trail (追踪). Kris then lifted the huge dog onto his shoulders and carried him down the mountain. “It was a long distance-a couple miles down a difficult rocky path,” says Lexie.

When they reached the stream, Kris laid him in the water as he knelt beside him and poured water on him. The ranger then picked him back up over his shoulders and walked all the way back down to the street for about an hour.

Lexie’s cousin Tori Matyola said, “The owner hiked down ahead of the ranger so that once he got down the mountain he had the car ready to take him straight to the vet. The dog was looking a little better by the time he got to the car and picking up his head.”

When she got home, Lexie, a pediatric (小儿科的) nurse from Hackettstown, New Jersey, posted the good deed on Facebook and it went viral with 35,000 people sharing the post and showing admiration for the ranger.

“This is a HERO,” Lexie wrote. “We are so lucky to have rangers like this who put animals before themselves. This ranger deserves recognition and a standing ovation (列队鼓掌) for his bravery, selflessness, and strength.”

1. What were Lexie and her fellow hikers worried about?
A.The dog’s struggle for more water.B.The dog’s lack of water to keep alive.
C.The owner’s unability to feed his dog.D.The owner’s tiredness to carry the dog.
2. What did Lexie think of Kris’s lifting the dog?
A.It was tough.B.It was simple.C.It was unbelievable.D.It was unexpected.
3. Why did Kris put the dog in the water?
A.To clean it.B.To feed it.C.To cool it.D.To relax it.
4. What did Lexie show in her post on Facebook?
A.Her appreciation to Kris.B.Her relief of the dog’s recovery.
C.The ranger’s example set to people.D.The ranger’s experience of saving the dog.

【推荐3】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.

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.
2. What does the underlined word “odyssey” in paragraph 2 mean?
A.Adventure.B.Break.C.Struggle.D.Victory.
3. How did the local residents feel about the elephants?
A.Excited.B.Confused.C.Embarrassed.D.Annoyed.
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.
