1 . Over the past four decades, more than 450 butterfly species have been hit by the falling numbers. In the US alone, the number of monarch butterflies (黑脉金斑蝶) has seen a drop of 80%, from scientists recording millions of them in the 1980s, and only 29,000 in 2020. It’s part of a wider possibility across the insect group. In 2017, scientists in Germany raised alarm bells after finding that insects had fallen by more than 70% in 30 years.

For farmers, monarch butterflies pollinate (授粉) a very large percentage of food crops. It is very important t protect them because their disappearance could have a huge economic influence. Butterflies are also helpful in the coal mine for other insects, as it is easier for them to feel the environmental change. and relatively easy to record.

Leading environmental organizations have been working hard to find new ways of recording the number of butterflies. As of now, there is no long-term data to develop good protection methods. The scientists wanted to address the challenge that long term recording programs worldwide have faced: they are focusing on training locals as insect experts, which requires much money. They came up with a new method to the problem. In Yasuni National Park, they hired park rangers (护林员) who were trained and then carried out recording. The rangers were able to recognize butterflies with an 85% success rate, which is important for these kinds of recording programs to be successful.

Compared with other recording projects, this study represents a long-term solution. “Our method increases the chance of recording in the long term by reducing the money spent on it such as wages,” said lead author Maria Checa. “Furthermore, it also offers opportunities for public organizations to achieve their environmental goals.”

3 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

Scientists exploring the ocean floor in Antarctica have found a larger group of fish nests than ever before. The discovery came     1     a surprise, and it will help scientists develop a more complete idea of the ocean food web in the area.

In the south Weddell Sea, not far from Antarctica’s Filchner Ice Shelf, scientists were    2     (amaze) to discover a group of about 60 million icefish nests on the ocean floor. Before this, the     3     (large) group of icefish nests that had ever been found includes less than 60 nests. Lilian Boehringer, a research student, was the first     4     (discover) the nests. “They were everywhere,” she told The New York Times.

The researchers used a special device called OFOBS to make two more four-hour “dives” ,    5     (try) to discover the limits of the nesting area. The nests scientists found were in the shape of     6     circle. Each nest held about 1,700 eggs. Usually, Weddell seals (海豹)    7     (spot) in the waters above the nesting site. Trackers     8     (fix) on some Weddell seals show that they dive all the way to the sea floor.

The team placed a camera on the sea floor before leaving,     9     will take a picture of the nests in the area     10     (two) a day for the next two years. They hope the pictures from this camera will help them learn more about the lives of the icefish.

4 . A new study discovers that sharks do sleep, and they often sleep with their eyes open. Since some sharks have to swim constantly to keep oxygen-rich water flowing over their gills (鱼鳃), people have long thought that they don’t sleep at all.

Researchers from Australia have now recorded a species of shark sleeping for the first time, finishing the long-standing debate about whether sharks sleep. To see if sharks were in fact asleep, the team analyzed the metabolism (新陈代谢) and pose of seven draughtsboard sharks (猫鲨) over 24 hours. When the sharks were resting for five minutes or longer, their oxygen consumption dropped, which suggested the animals were sleeping. And the researchers also noticed that the sharks changed their posture by lying flat and closer to the ground.

The sharks sometimes slept with their eyes shut as well, though, mostly during the day. At night, they tended to keep their eyes open more often, leading researchers to suspect that the sharks’ eye closure might have more to do with light than the sleep state itself. “Not only are sleeping sharks less responsive to their surroundings, but they also have lower metabolic rate,” said Michael Kelly, an ecophysiologist at La Trobe University.

“Sharks are an important group as they are the oldest living jawed vertebrates (颌类脊椎动物) — a character they share with us,” Michael Kelly said. “Sharks have been swimming in the sea for over 400 million years and have evolved very little in that time. Understanding how and why these animals sleep will provide important understanding into the function of sleep and how the animal has evolved over time.”

The team points out that more research will be needed to see if other species sleep like the draughtsboard sharks. Next they plan to continue to analyze the sharks’ brain activity while they sleep, to learn more about their waking and resting states.

5 . Lillian, 17, had just started working as a lifesaver at a beach in Australia on New Year’s Eve when beach-goers started to point and shout at the water. The workers quickly examined the situation and saw that a kangaroo had jumped out of the bushes (灌木丛) — straight into the sea.

The animal seemed confused by the fishermen standing on the rocks. So instead of turning back and heading back into the bushes, it jumped right into the water! The poor thing bobbed(摆动)around in the waves and went underwater several times before Lillian decided to take action.

As with any other animal rescue, it’s important to approach the situation with prudence. Wild animals that are stressed can become dangerous to their rescuers, and Lillian was aware of the risks as she took her rescue board and hit the water at a run. “It just didn’t want to come on to the beach because it was kind of scared,” she said. “I was trying to figure out how to get it on the board. But considering that it’s a wild animal, even though I was helping, I wouldn’t want to be hurt by it or make it more stressed out.”

As beach-goers recorded the rescue on their phones,Lillian paddled (用浆划船) behind the animal carefully and guided the kangaroo onto the beach. As soon as Lillian’s feet touched the sand, the beach erupted in cheers for her!“It was quite special. As people there were cheering and clapping, the kangaroo was just sitting there up in the bushes staring at me, as if it was conveying something with its shining eyes,” Lillian said. “I didn’t think that was going to ever be my first rescue, I may have more rescues in the future, but none would be as memorable as this one.”

1. What happened to the kangaroo?

A．It jumped off the rocks by mistake,

B．It jumped into the sea by accident,

C．It was forced to leave the bushes.

D．It was washed away into the sea.

2. What does the underlined word “prudence” in paragraph 3 probably mean?

A．Inspiration.

B．Hope.

C．Care.

D．Shock.

3. How did the kangaroo react to its rescuer?

A．It couldn’t wait to leave her.

B．It was worried about her safety.

C．It was confused about her action.

D．It seemed grateful for her help.

4. Which of the followings can best describe Lillian?

A．Far-sighted and independent.	B．Talented and positive.
C．Brave and cautious.	D．Determined and ambitious.

7 . 阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。

The Dog Who Saved Our Family

We met Max at the pickup area of Alaska Airlines five years ago. He was a standard poodle(狮子狗)born on Valentine’s Day in 2017， and came to us in a small blue box. We had adopted him from an out-of-state raiser who posted the news on the social network. Our only request was that he have a calm behavior, able to bear the pushing and hugging of our eight-year-old daughter and six-year-old son.

We were a sweet little family:me,my husband, and our children, Sophie and Jake. But for years I’d felt as if we wouldn’t really be complete until we had a dog. Also, my husband worked in a business company and had to travel some 200 days a year for his job, and I knew I’d feel safer with a large animal sleeping by the door.

When we opened the box, the last piece of our puzzle fell into place. With his black hair and intelligent eyes,Max was beautiful. He was so small that he fit into the palm of my hand, his big paws lapping over the sides. He was also a little bit scared. As I pulled him close,I felt his heart pound and wondered if we’d done the right thing, taking him from his mother. But it was too late. Sophie and Jake were already fighting over who would hold him next and who should have the right to take a bath for him.

Over the following months, we spent endless hours watching Max play with his Kong toy or roll around the living room floor. Like most poodles, he was smart. He mastered house-training quickly and never chewed on our furniture or shoes. He considered himself one of us.
