1 . 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。

In the coming weeks, China Daily will be publishing special reports focusing    1     the ongoing development of the country’s national park system, looking at areas coming under stronger    2     (protect) and the species benefiting from many new    3     (facility).

The Sanjiangyuan National Park, covering 190, 700 square kilometers,     4     (be) China’s largest such facility. It is about 14 times the area of Yellowstone National Park in the United States and 19 times    5     (large) than the Banff National Park in Canada. Standing at an average altitude of more than 4, 500 meters, the sparsely populated park in Qinghai Province is the ideal habitat for many wildlife species,     6     (include) Tibetan antelopes and snow leopards.

Sanjiangyuan,     7     means “source of three rivers”, is home to the headwaters of the Yangtze River, the Yellow River and the Lancang River    8     (know) as the Mekong once it leaves Chinese territory. As such, the parks has been dubbed “Asia’s water tower”. 2% of the total water volume of the Yangtze River, 49% of the Yellow River and 17% of the Lancang River come from the Sanjiangyuan area, with tributaries providing the rest.

Decades ago, climate change and human activity caused serious    9     (environment) degradation in Sanjangyuan, which resulted in a large number of lakes drying out and wildlife numbers falling    10     (sharp). In 2016, the pilot program for the Sanjiangyuan National Park management system was launched, and the area was officially designated as a national park in September in 2021.

2 . Pet owners have a big responsibility when it comes to taking care of their furry friends Unfortunately, many pet owners make common mistakes as follows.

● Not providing enough exercise or mental stimulation for your pet

All pets need regular exercise and mental stimulation to stay healthy and happy.     1     Mental stimulation is also essential to keep your pet fit. You can give your pet puzzle toys, play new games with them, or teach them new tricks.

● Over feeding

You might think you’re doing your pet a favor by giving them extra treats, but overfeeding can do more harm than good.     2    . Therefore,ensure you’re following the feeding guideline on the bag and not giving in to those puppy-dog eyes too often.

● Not socializing your puppy

Socialization is key to a well-behaved and happy dog. Make sure to introduce your puppy to different people, animals and situations.     3    

    4    

Pets are great at hiding their pain and discomfort, so it’s important to watch for any change in behavior or appetite. Don’t hesitate to bring something up with your vet if you notice something off.

To help avoid these types of errors,Wanda Morgan, Chief Editor of Workout Lunatic, gives the following tips.

● Positive reinforcement

Positive reinforcement is always the way to go when training your pet. Use treats and verbal praise to encourage good behavior instead of punishment or scolding.

● Addressing underlying anxiety causes

    5    . Give your pet plenty of engaging activities and playtime to keep their minds and bodies active and happy.

A．Ignoring signs of illness

B．Not trusting your puppy

C．It can help them grow confident and well-adjusted

D．It can lead to obesity and other serious medical conditions

E．Mental exercise is crucial to your pet as much as physical exercise

F．Anxiety-based behavior can stem from a lack of attention or stimulation

G．Without enough physical activity, your pet may become overweight or bored

3 . Lotus, ginkgoes, Chinese roses .... On the campus of Beijing 101 Middle School, there are more than 200 types of plants. To keep a record of the rich natural resources there, the school’s students made a beautiful book: Flora of 101.

“We chose 30 plants to show with pictures, basic information and particularly, a poem for each plant written by ourselves,” said 17-year-old Wang Jianyuan, the chief editor of the book.

The poems are not just describing the plants. They also reflect students’ stories. “One day I was a little upset when I smelt a fragrance (芳香). Looking down, I saw humifuse euphorbia, or dijincao (地锦草), a very common plant. Suddenly I felt comforted—it just grows and gives off a sweet scent, regardless of people stepping on it. So I wrote a poem for it,” said Wang Jianyuan.

“Every poem in the book shows students’ unique understanding of the plants, showing our school’s character and spirit through the book,” Wang Jianyuan added.

Wang Jingyue, 17, painted the pictures for the book. “Many students in our school love painting. We took photos of the plants and drew them in a realistic (现实主义的) style,” Wang Jingyue said. “Siting there and painting give us a chance to closely watch a plant and connect with it. It feels amazing.”

The students plan to print 300 copies of the book this September to give out to new students. “We hope the younger students can fall in love with the plants and the ecosystem in our school. Hopefully, when they walk along the green alleys (小径), they can find peace and inspiration,” said Wang Jianyuan.

4 . Some breathtaking blue lakes may not be so blue in the future, thanks to climate change. In the first global record of lake color, researchers estimate that roughly one-third of Earth’s lakes are blue. But, if average summer air temperatures should rise by a few degrees, some of those pure waters could turn green or brown, the team reports in the Geophysical Research Letters.

Lake color depends in part on what’s in the water, but factors such as water depth and surrounding land use also matter. Compared with blue lakes, green or brown lakes are caused by more algae (水藻), sediment and organic matter, says Xiao Yang, a hydrologist at Southern Methodist University. If some lakes do become less blue, people will probably lose some of the resources they have valued.

Yang and his colleagues used satellite photos from 2013 to 2020 to analyze the color of more than 85, 000 lakes that are detectable around the world. The scientists found that lakes in cooler regions, with average summer temperatures below 19℃, tend to have a blue color compared to lakes with warmer water. This warmer environment encourages more algae growth, and thus its tint is changed, giving it a green-brown look, according to Yang. But what is worth mentioning is that the average summer temperatures may increase another 3℃—an amount that scientists think is possible by the end of the century.

Lake color can suggest the stability of a lake’s ecosystem, with shifting shades indicating changing conditions for the creatures living in the water. One benefit of the new study is that it gives scientists a baseline for assessing how climate change is affecting Earth’s freshwater resources. Continued monitoring of lakes could help scientists detect future changes.

5 . Fog is a common climate phenomenon in life, and different environments can lend to diverse forms of this low-lying cloud.

Frontal fog

This fog is formed when raindrops change into gas. The rain falls through warmer air into cold stable air and forms a fog layer near the ground. When enough rain has filled the cold layer of air, foggy clouds become visible.

Radiation fog

This type of fog forms during mild weather, when there is little wind and the skies are clear of other clouds. The air near the ground cools and turns into a layer of fog, which grows overnight as the air cools further. When the sun heats the air again the following day,the fog begins to dissipate.

Advection fog

Advection fog forms in a similar way to radiation fog, but is caused by warm air moving horizontally over colder air rather than the vertical loss of surface heat. When the warm air approaches colder ground, it gradually forms fog.

Sea fog

Warm and moist air that forms over a body of water becomes cooler as it’s transported with the wind. This cooling causes sea fog to form. When it reaches the warmer air above land, it may begin to dissipate.

1. When does frontal fog form?

A．In cold days.

B．In rainy days.

C．In mild days.

D．In sunny days.

7 . Thirsty or stressed plants do not suffer in silence. Instead, they make high-pitched(尖锐的) sounds, according to a study published in the journal Cell.

The reason why you have probably never heard the plants’ sounds is that most humans are only able to hear sounds as high as 20 kilohertz (kHz), but the plants made sounds mostly between 40 and 80 kHz, Lilach Hadany, a co-author of the study at Tel Aviv University, tells Business Insider’s Marianne Guenot.

Plants, obviously, do not have organs to make sounds. Lilach says, the present popular theory on how they make noises centers on plants’ xylem(木质部), the tubes that transport water from their roots to their stems(根茎) and leaves. In the process of transporting, when an air bubble(气泡) forms or breaks in the xylem, it might make a little noise; bubbles are more likely to form when a plant is suffering from drought. But the exact process requires further study, Lilach explains.

To listen in to plants, Lilach and her co-workers placed tobacco and tomato plants in small boxes equipped with microphones. First, they stopped providing water to some plants in the boxes and cut the stems of others. Then, the microphones were used to pick up any noises made by the plants even though they couldn’t hear them. Researchers found that the sounds did show the specific types of stresses plants were experiencing. Thirsty tomato and tobacco plants made an average of about 35 and 11 sounds per hour, individually, while cut tomato and tobacco plants made 25 and 15 noises per hour.

In theory, these recorded sounds could help farmers know about which crops are most in need of water. “When more and more areas are exposed to drought due to climate change, efficient water use becomes even more important, for both food security and ecology,” Lilach with her co-workers write.

1. Why do humans fail to hear the sounds of plants?

A．The sounds are stressful.

B．The sounds are beyond human’s hearing range.

C．The sounds are low-pitched.

D．The sounds are between 20kHz and 40kHz.

2. What might cause thirsty plants to produce sounds?

A．Suffering from lack of air.

B．Stems and leaves transporting water.

C．More air bubbles gathering in the roots.

D．Air bubbles’ forming or breaking in the xylem.

3. What did Lilach and her co-workers find in the study?

A．Noises can be picked up by microphones.	B．Plants make more sounds in small boxes.
C．Cut plants suffer the same as thirsty ones.	D．Different sounds indicate plants’ stress types.

4. What’s the potential use of the sound recordings?

A．To harvest the crops.	B．To solve the food problem.
C．To locate the thirsty crops.	D．To prevent climate change.

8 . Environmental groups have long criticized the private jets(喷气式飞机) for being a large contributor to global carbon dioxide emissions, and last week, environmentalists made headlines by interrupting a private jet trade show in Switzerland.

Private jets often cover shorter distances than commercial ones. They are generally less efficient(高效的) and their emissions per passenger are much higher. According to data from European non-profit Transport and Environment, private jets can be 5 to 14 times more polluting than commercial planes, and 50 times more polluting than trains. Research made by Greenpeace showed that private jets in Europe alone emitted 3.39 million metric tons of CO₂ in 2022, nearly equal to the emissions from 753,000 gas-powered cars in the US driven for a year.

But experts say the private aviation(航空) industry can still play a role in the global fight against climate change, and some in the industry are looking at creative ways to diminish its environmental impact.

As a member of the International Air Transport Association(IATA), along with other major commercial airlines, Dubai-based private aviation company Jetex launched the 2050 Project: the zero carbon emissions.

“Jetex is always thinking about how to cooperate with everyone to deal with climate change,” said Dr. Suzanne, a professor of aviation at the University of Waterloo. “And now it is working on changing all of its locations into fully green ones in the future. Once it succeeds, it will offer a new approach to the environmental protection.”

Through a partnership with oil company Neste, in 2021 Jetex started offering sustainable aviation fuels(SAF), made from renewable waste, to passengers at its Helsinki Airport. That same year at its Paris Le-Bourget Airport, it began offering SAF produced by French company TotalEnergies, made from used cooking oil. A limited supply of SAF means it isn’t available at every airport, but the company says it wants to make SAF a fuel option to its travelers across all its locations worldwide.

1. What do we know about private jets according to the first two paragraphs?

A．They enjoy great popularity.

B．They charge passengers more.

C．They give off more carbon dioxide.

D．They travel farther than commercial planes.

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

A．Expand.

B．Present.

C．Overlook.

D．Reduce.

3. What is Dr. Suzanne’s attitude to the “2050 Project”?

A．Indifferent.

B．Carefree.

C．Tolerant.

D．Supportive.

4. Which can be a suitable title for the text?

A．Private Jets’ Green Path.	B．The Birth of SAF.
C．The Future of Commercial Planes.	D．Jetex’s Cooperation with Others.

9 . The earthworm is widely distributed, with 4000 species in the world and more than 300 species in China, where they are in demand as fishing bait, livestock feed, and components of traditional medicine. Known as “ecosystem engineers,” earthworms also play a vital role in the biogeochemical cycle. They can affect the biological, chemical, and physical processes of the ecosystem. In recent years, poachers in China have started using soil electrocution to capture earthworms, putting earthworm populations and ecosystems at risk. In February, China banned the practice.

In the past, earthworms in China were captured manually, which limited the number that could be caught in a short amount of time and did not threaten the earthworm population or the soil ecosystem. In contrast, applying electric current to the soil can catch about 150 kg of earthworms in a day. Removing earthworms at this scale threatens the species with local extinction and robs the targeted ecosystem of the benefits they provide.

This capture method threatens other species as well. The electric current may kill or harm soil organisms beyond earthworms. The changes could disrupt the food cycle or birds, arthropods, and mammals that depend on earthworms as a food source. The sharp decrease of earthworms in the soil may also affect soil fertility and productivity, reducing crop yields.

Electric earthworm capture has quickly become widespread, because earthworms are not included on the list of protected wild animals in China. There have been few legal punishments for using the approach, despite the damage it causes. In February, the Chinese government took a step to ban electric capture of earthworms and other activities that damage the soil ecosystem. However, the financial benefits of large-scale earthworm poaching may provide poachers with an motivation to continue using electric capture despite the ban. To carry out the ban effectively, China should pass laws that specify how poachers will be punished if they continue to use soil electrocution.

1. What does the author want to convey in the first paragraph?

A．The earthworm is found everywhere.	B．The earthworm is used as fishing bait.
C．The earthworm is captured.	D．The earthworm is endangered.

2. Why does the author mention “manual capture” and “electric capture”?

A．To give an example	B．To explain a capture method
C．To clarify a concept	D．To make a comparison

3. Why do poacher keep using electric capture?

A．Because they want to get a lot of money.	B．Because they like electric capture.
C．Because they ignore the ban.	D．Because they hate earthworms.

4. Which of the following is a suitable title for the text?

A．China Bans Electric Capture of Earthworms

B．Electric Earthworm Capture Became Widespread

C．Earthworms Play a Vital Role in the Ecosystem

D．Earthworms Are Captured by Soil Electrocution
