4 . Lay eggs and make noises — that’s it? Anyone involved in chicken farming knows that the animals are capable of much more. Researchers have found evidence that roosters (公鸡) could recognize themselves in a mirror. Whether this is successful, however, depends on the experimental contexts.

Whether animals can recognize themselves and thus have self-awareness is one of the central questions in behavioral research. The mark test, a classic test for self-recognition came to the scientists. In the test, if an animal stands in front of a mirror and begins to explore the colored mark placed on its body, this is considered proof that it recognizes its reflection as itself.

“However, our goal was to conduct the mirror test in an environment that is better adapted to the ecologically relevant behavior of the roosters,” says Sonja, a researcher from the University of Bonn. She came up with the idea of using a natural behavior of roosters for the experiment.

Initially, the researchers set up a test area and placed a net to separate two compartments (隔间), through which the roosters could see each other. Then a picture of a fox was placed onto the ceiling of one compartment. Faced with the predator, the roosters let out 77 alarm calls in the presence of a partner, but only 17 when they were alone. The result shows that most roosters, faced with a fox, do alarm partners, which is the perfect illustration of the animals’ self-awareness. The next step was to place a mirror between the two compartments instead of the net. In all, only 25 alarm calls were let out. “The result indicates that the roosters don’t mistake their reflection for a partner, and possibly recognize themselves in their mirror image,” says Sonja.

For comparison, the team also performed the classic mark test. Here, the roosters didn’t recognize themselves in the mirror. The research team sees clear evidence that the classic mirror-mark test produces more reliable results when the behavior of the particular species is included in an ecologically relevant context. “In the classic situation, a rooster may not show self-recognition,” says Sonja. “But when a fox threatens him, it becomes clear that his reflection is not another rooster, but himself.” Further research on animals’ self-awareness is needed so as to better understand animal rights and animal welfare.

1. What is the purpose of the mark test?

A．To explain why animals show certain behavior.

B．To discover what behavioral research focuses on.

C．To tell whether animals can identify their mirror image.

D．To reveal how animals get used to the natural environment.

2. What does the underlined word “predator” in paragraph 4 mean?

A．Enemy.

B．Partner.

C．Researcher.

D．Reflection.

3. Why did the researchers add a mirror in the second step?

A．To present the experiment result.	B．To change the experimental condition.
C．To replace the experiment subject.	D．To simplify the experimental process.

4. What is the passage mainly about?

A．Animal behavior draws researchers’ attention.

B．Animal welfare deserves more human efforts.

C．Roosters’ self-recognition works in classic mark tests.

D．Roosters’ self-awareness improves in threatening contexts.

5 . Have you ever got the feeling that your dog is judging you? Well, you’re in for a surprise because it’s actually your dog who might be viewing you with a critical eye. Eliza Fletcher and her colleagues wondered whether dogs might rate us in terms of our skillfulness, particularly when those skills might come in handy for our four-footed little friends. So they set up a simple experiment.

They showed 60 dogs two persons opening containers. One person is competent. That person was able to pop open the top after just a couple of twists while the other person failed at this task. That person tried to open the lid, but then gave up. The actors repeated the performance on a second container, with the same results. Then the researchers handed both actors a third container. In some trials, this container was empty. In others, it contained a treat. And what they found was that female dogs spent more time staring expectantly at the person who had previously demonstrated container-opening know-how. And they were more likely to approach the competent person, but only when they thought they might get free food. Dogs in the empty condition showed no preferences.

So, why would females be more careful observers of people’s performances than males? Female advantage in the social cognitive domain (认知领域) has been reported across many species including humans. In other words, in many cognitive studies, furry females seem to show a higher social IQ than males. And sex differences have been seen in other dog studies. For example, females look at their owners more frequently and longer than males when facing unsolvable task. Female dogs solve significantly more tasks than males in social learning task.

So, next time Fifi looks at you with those puppy dog eyes, you might be thinking, what a good dog! But she might be thinking, eeem, you could do better.

1. Why did Eliza Fletcher do the experiment?

A．To figure out the rate of human skills.

B．To prove dogs have better skills than humans.

C．To test whether dogs judge human’s skillfulness.

D．To find out whether some human skills are easy for dogs.

2. How does the author develop paragraph 3?

A．By making comparisons.	B．By making inferences.
C．By giving explanation.	D．By analysing figures.

3. What is the purpose of the last paragraph?

A．To remind people of the research result.

B．To entertain readers with a vivid picture.

C．To prove that dogs are intelligent enough.

D．To show close relation between men and dogs.

6 . Saving the environment might seem like a tall order, but living an environmentally friendly life is actually quite easy.     1     Read on for some practical tips on how a single individual can help save the environment.

Recycle

Recycling is a simplest lifestyle to lower the amount of environmental waste. Every resident can get involved by taking advantage of nearby recycling services.     2     For instance, some places may not accept glass, while others might require you to separate the different materials. If you dispose of something improperly, the whole load will likely be rejected and end up in a landfill.

Buy locally-sourced foods

Eating fresh, local food consumes less fuel and packaging materials. Shipping products by truck, rail, flight, or boat creates pollution and goes against an environmentally friendly lifestyle. Instead, shop at local farmers’ markets and grocery stores stocking locally-sourced products.     3     .

Cut back on driving

Applying alternate forms of transportation consumes less gasoline.     4     If that isn’t an option, consider organizing carpools or using public transportation. By doing this, you help reduce traffic jams and the overall amount of gasoline consumption. Also, combine multiple trips into one to help minimize the distance traveled and fuel consumed.

    5    

Advocacy allows more people to create a positive impact. Spread the word about environmental conservation by sharing some of the lifestyle changes you’ve made on social media and in conversations with people around, calling on everybody to play a role.

A．Cut back your carbon footprint

B．Walk or ride a bike whenever possible

C．Encourage others to help save the environment

D．Check the regulations to ensure you use them properly

E．The topic of preserving natural resources entertains everyone

F．With just a few small lifestyle changes, you can make a difference

G．Alternatively, use community-supported services to get fresh produce regularly

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。

For many years, my only companion was our dog, Sno. A small but mighty Bichon Frise, our dog may have looked ordinary, but he was smart, creative, and always ready for ice cream and rolling at my request. While I worked, he slept, waking to chase the red cat from next door, greet a delivery person, or sit in the sunshine.

We didn’t agree on everything, especially when to get up and when to go to bed. He sighed with boredom when a project was due and I didn’t have time to play. He didn’t understand weekends, deadlines, and visitors who left him. However, we both agreed on walking.

At least once a week, we took a long walk to the beach. For him, there were tall grasses and exciting smells. For me, there were other dog walkers and neighbors to catch up with. We returned tired, thirsty, and very happy.

Being a dog with huge ambition and short legs, Sno needed several breaks along the way. The one at the entrance to the beach was his favorite, possibly because he knew we were circling back home. There, on a windy summer day, he looked up at me just as I was looking down at him. We both grinned (咧嘴笑). This was the best walk ever.

When he was old and dying, our walks were shorter and closer to home. I’d take him for a walk and then go out for my own walk, wandering around the beach like we used to do. I always grinned when I got to the entrance to the beach, remembering that summer day when he was young and energetic.

In his final days, Sno still insisted on walking. It took twice as long to take even the shortest walk, but we enjoyed every step. Then came that Sunday when he leaned hard toward the beach walk. How could I refuse his last-walk wish?

8 . Animals were the real pioneers of space flight. Let us learn about some animals that have been to space.

A. Fruit flies

On February 20, 1947, the United States sent some fruit flies into space to study the impact that cosmic radiation (宇宙辐射) might potentially have on astronauts in the future. They chose flies because they are genetically similar to humans.

When they returned to Earth, the scientists found the flies alive, with no evidence of the effects of radiation.

B. Mice

Mice have long been used to find out more about how space travel will affect the human body. In fact, NASA has recently published a study of mice housed at the International Space Station. It shows that mice quickly adapt to microgravity (微重力) conditions.

The very first mouse went into space in 1950, reaching an altitude of 137km. However, unlike the fruit flies, the mouse died when the rocket broke into parts due to a parachute (降落伞) failure.

C. Dogs

Laika, a Russian homeless dog, went to space on November 3, 1957. She was picked up on the streets and was thought suitable because she had a gentle temperament (性情) and behaved well. The scientists also believed a homeless dog would be better at dealing with difficult conditions like microgravity than a pet dog.

Laika is famous for being the first animal to orbit (环绕……运行) the Earth. However, she never returned.

D. Spiders

In 1973, two garden spiders called Anita and Arabella were used in an experiment to see if they could still build webs in space.

Both spiders managed to build webs, even though the webs were slightly finer than on Earth. The study showed a great deal about the effects of microgravity on motor response (运动反应).

1. What can we learn about the mouse astronaut?

A．It failed to come back alive.

B．It couldn’t survive in microgravity conditions.

C．Its genes were similar to humans’.

D．It was the first animal to be sent to space.

2. Laika was chosen by the scientists for all the following reasons EXCEPT ________ .

A．her good temperament	B．her identity as a pet dog
C．her ability to deal with microgravity	D．her good behavior

3. What’s the purpose of sending the two spiders to space?

A．To compare the quality of webs they made on Earth and in space.

B．To study the impact of cosmic radiation on their survival.

C．To see how fast they could build webs in space.

D．To see whether they could build webs in space.

9 . Growing up in Canterbury, Scartozzi recalls swimming in rivers as part of her childhood. When she returned many years later, however, she noticed things had changed. “Some of the places where I could swim before now have signs saying ‘polluted water, do not swim’,” she says. “I wanted to take my kids to places to swim but we couldn’t because these signs were up.”

Although the experience was sad and surprising, it has also served as fuel for Scartozzi, who’s now focusing on restoring the health of waterways. Her company called eCleanEnvirotech is developing technology to remove pollutants from waterways such as rivers, ponds and streams. It involves feeding polluted water into a system housing microbes (微生物) that eat or break up the pollutants.

The “engineered” nature of the technology, Scartozzi explains, means it’s adaptable for different environment conditions. Each system can be personalized with its own unique “soup” of microbes to remove the pollutants in any waterway where it is installed (安装).

Other advantages of the technology, she says, are that it can process water relatively quickly and that it can be used to treat waterways in a variety of sizes and locations.

She says she hopes to create cleaner water for the benefit of future generations. “My passion is around restoring the health of these waterways. And my purpose is to do anything that I can to return them to their former condition. That’s what drives me every day. If I can do anything, it is so that in the future, my kids and grandchildren have somewhere where they can go swimming and fishing.”

1. What can we learn from the first two paragraphs?

A．Scartozzi and her kids were fond of swimming.

B．The experience inspired Scartozzi to clean up waterways.

C．Waterways in the world were unsuitable for swimming.

D．The company focuses on the development of the technology.

2. What is one advantage of the technology?

A．It is convenient and economic.	B．It can be used in limited waterways.
C．It functions slowly but effectively.	D．Its system is flexible and efficient.

3. What is the goal of Scartozzi?

A．To introduce her company.	B．To swim and fish in the river.
C．To regain healthy waterways.	D．To educate future generations.

4. Which of the following can best describe Scartozzi?

A．Energetic

B．Curious.

C．Outgoing.

D．Responsible.

10 . 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。

More than 11,000 scientists from 153 countries have sounded the alarm on climate change. In a paper     1     (publish) last week in the journal BioScience, they signed a declaration (声明) stating clearly that planet Earth is facing a climate emergency, saying that if no changes     2     (make), the world will face untold suffering. The evidence that the scientists collected reveals an undeniable truth    3     human activities have been causing global warming from the fast rise of fossil fuel consumption    4     the increase in greenhouse gas emissions (排放) over the past 40 years.

The scientists also gave some instructions to fight against global warming,     5     (propose) six actions to prevent further disasters: stabilizing population     6    (grow) by investing into family-planning services and girls’ education, replacing fossil fuels, cutting the emissions of climate pollutants, eating less meat, restoring and protecting ecosystems, and building     7    carbon-free economy.

The scientists say the climate crisis is     8     (close) related to human activities, so they call on people     9     (change) their life styles. But these measures are comparatively abstract.    10    , it is high time for policymakers to figure out more practical measures that can bring down carbon emissions.
