2 . Would you know what to do during a big earthquake? Scientists have some advice for us.

If the ground begins shaking while you are driving stop your car on the roadside and stay in it. If you are in a tall building, don’t use the lift and never jump out of the windows. When you are in a living room, find a strong table or rush into a smaller room like washroom. Then lie down your body. Take care of your head. When you are in a public place, like supermarket or cinema don’t crowding jam (拥挤), or you may fall over and get hurt. Cross your arms to protect yourself . You can also find a place to hide.

After the main shake quickly run out of the dangerous building for there will be small earthquakes. If you are safe, remember not to engage the phone line, keep it free for rescue (援救) using.

3 . One day when Jack was walking in the park, he saw a woman, who lived a few miles away, sitting on a bench (凳子) with a dog beside her. The dog was looking up at the woman.

Jack walked up to the woman and said, “Hello, Sue how are you? May I sit and talk with you for a while?” “Of course, please sit down,” Sue said. Jack sat down next to Sue on the bench, and they talked quietly together. The dog continued to look up at Sue as if waiting to be fed.

“That’s a nice dog, isn’t he?” Jack said pointing at the animal.

“Yes, he is. He’s handsome. He’s a bit of a mixture but that’s not a bad thing. He’s strong and healthy.”

“And hungry,” Jack said.

“He hasn’t taken his eyes off you. He thinks you’ve got some food for him.”

“That’s true.” Sue said.

“But I haven’t.”

They both laughed and then Jack said, “Does your dog bite (咬人)?”

“No,” Sue said. “He’s never bitten anyone. He’s always gentle and friendly.”

Hearing this, Jack decided to hold out his hand and touched the animals head. Suddenly it jumped up and bit him.

“Hey!” Jack shouted. “ You said your dog didn’t bite.”

Sue replied in surprise, “Yeah, I did. But this is not my dog. My dog’s at home.”

4 . Gorillas (大猩猩) in films such as King Kong and Tarzan are wildly beating their chests when under threat. Researchers have tried to find out what the behavior might mean, and they doubt that the gorillas exhibit this behavior not to start fights, but to prevent themselves — and chest-beating could be used to advertise (展示) their body size to other gorillas.

Scientists observed 25 wild male mountain gorillas for over 3,000 hours. The research team used audio (音频) equipment to record the sound frequency (频率), rate, duration, and amount of chest beats. To determine each gorilla’s size, the researchers used cameras to photogragh and measure each gorilla’s back.

Although the rate, duration, and amount of beats did not correlate (相关) with the size of the gorillas, sound frequency did , the researchers report. The team also noticed that larger gorillas produced deeper-tone chest drumming. Previous research has shown that a gorilla’s larger body size is linked to reproductive success and social rank (地位). The chest-beating could be a way for the gorillas to advertise their size to others and, in turn, avoid fights that could result in serious injury or death.

Though gorillas can obviously observe size just by getting a good look at others, the researchers suggest chest beating is copper-bottomed when trying to communicate through a thick forest. The sounds gorillas created by beating their chests are powerful enough to travel long distance through thick forests and signal others their size and fighting ability.

Animal expert Anna Nekaris says it would be interesting to see if smaller gorillas can imitate the deep tones of larger ones in future studies. Nekaris says, “For now, the researchers will continue to study chest-beating to see if the action can pass on other information, such as dominance rank (优势等级), sex, and individual identity, to nearby gorillas.”

A．Its fingdings.

B．Its method.

C．Its samples.

D．Its purpose.

2. Why do some gorillas beat their chests?

A．To declare war on other gorillas.	B．To celebrate their victory in a fight.

A．Scientific.

B．Interesting.

C．Reliable.

D．Skillful.

4. What does Nekaris suggest researchers study in the future?

A．If smaller gorillas can make deep-toned chest drumming.

B．If gorillas’ chest-beating contains other information.

C．If larger gorillas are better at using their body influence.

D．If gorilas have other communication skills.

5. Which section may the passage come from in a newspaper?

A．Health.

B．Entertainment.

D．Sports.

5 . 阅读下面材料，在空白处填入适当的内容或括号内单词的正确形式。

The Great Wall

The Great Wall, a     1     (memory) landmark, is one of the most appealing attractions in China. It     2     (fascinate) the minds of many in the world in the past several decades.

The Great Wall resembles a Chinese dragon circling the mountains,     3     (wind) its way westwards over the vast land of China.     4     (doubt), looking down at the Great Wall from the sky is amazing. As early as the Spring and Autumn Period, each principality (候国) in China constructed its own “great wall”     5     (defend) itself from enemies. They built many a “great wall” in the early days,     6     extended several hundred li length. The Chinese name “Chang Cheng” or “Long Wall” came     7     existence because of the length of the wall. According to     8     (record) put down in Chinese literature, as many as 20 principalities and dynasties took part in reconstructing the Great Wall. If we add the length of the wall     9     (build) in each dynasty, the total comes to over 50,000 km.

The Great Wall is a symbol of Chinese civilization, It has been put down on the World Heritage List. It is     10     wonder of the world and the pride of China.

6 . Wildlife biologist Purnima Devi Barman remembers the first time she ever saw the nest of a greater adjutant stork (秃鹳) in a tree near her grandmother’s home. Her grandmother would tell her stories about birds and animals under the tree. The love for the natural world developed in those years led Barman to devote her life to saving the endangered greater adjutant stork.

Known as the Hargila in Assam, the greater adjutant stork is the second-rarest stork in the world. Unlike pandas or lions, whose attractive appearances help gain widespread support for their protection, these tall, bald, clumsy birds meet with bias in conservation campaigns.

“Hargilas also bear a reputation of bringing bad luck,” says Barman. “What was the point of writing my paper on them if there was no way of actually saving these birds? I had to start with changing the misconception.”

Not one to shy away from a challenge, Barman put her PhD on hold and set to work. “I started engaging with the women in the village. In our experience, educating and securing the participation of women ensures that the learning passes on to the next generation,” Barman says.

Today, around 400 women have been trained to work on conserving this rare bird. The group’s activities include awareness-building in schools and plantation drives in which 45,000 trees were planted to support the stork’s future populations.

A key component allowing Barman to successfully integrate conservation efforts into the village cultural life was her idea of building related livelihoods. Weaving (纺织) is a long-standing craft in Assam, so Barman created a self-help group employing women to weave stork patterns on textiles. This innovative idea was highlighted at the UN Champion of the Earth Awards she won in 2022.

Currently the number of greater adjutant nests in Assam’s Kamrup district has grown from 28 in 2010 to more than 250. The once unlucky stork is now a symbol of community pride, its pictures appearing on bags, blankets and celebration decorations.

1. What motivated Barman to save the greater adjutant stork?

A．Her interest in observing nests.	B．Her passion for doing research.
C．Her love for nature from childhood.	D．Her grandmother’s encouragement.

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

A．Prejudice.

B．Support.

C．Danger.

D．Success.

3. What was a major challenge Barman faced in conserving the greater adjutant stork?

A．The stork is common in appearance.	B．The stork was believed to be unlucky.
C．She had not finished her paper for PhD.	D．She lacked experience in wildlife conservation.

4. How did Barman make conservation efforts part of the village cultural life?

A．By creating related jobs.	B．By teaching women to weave.
C．By planting trees in the village.	D．By advertising local products.

7 . For some ant queens, the secret to long life might be a self-produced insulin (胰岛素) blocker. Ant queens are famously long-lived even though they shouldn’t be. Generally, animals that put lots of energy into reproduction sacrifice some time off their life. But ant queens produce millions of eggs and live an extraordinarily long time compared with worker ants that don’t reproduce.

Now, researchers have shown how one ant species pulls off this anti-aging great work. When queens of the species, Harpegnathos saltator (跳跃蚁), are prepared to reproduce, a part of what is called the insulin signaling pathway gets blocked, slowing aging. In a rare behavior for ants, when a queen H. saltator dies, some female workers begin competing in fights for the chance to replace her. These hopeful royals start laying eggs and then change into queen-like forms called gamergates (雌工虫). When a worker changes to a gamergate, her life length becomes five times as long as it was. But if she doesn’t end up becoming a queen and goes back to a worker, her lifetime shortens again.

The researchers researched this behavior in these ants. It turns out that H. saltator gamergates extend their lifetime by taking advantage of a split in the insulin signaling pathway, the chain of chemical reactions that drive insulin’s effects on the body. One branch of this pathway is involved with reproduction, while the other is linked to aging.

Examining patterns of gene activity, expert Yan and his colleagues found that gamergates have more active insulin genes than regular worker ants and, as a result, have increased metabolic (新陈代谢的) activity and physical development. But the secret sauce protecting the ants from the insulin’s aging effects appears to be what is called Imp-L2, which blocks the branch of the insulin pathway linked to aging. The branch involved in reproduction, however, remains active.

These results represent a leap forward in our understanding of extreme social insect lifetime, while also showing an anti-aging evolutionary adaptation that hasn’t been seen in the wild before.

8 . Want to eat healthy and also save the planet?     1     Making simple substitutions, such as switching from beef to chicken or drinking plant-based milk instead of cow’s milk, would help both the planet and your health.

How do our food choices affect climate change?

Food production accounts for about 20% of greenhouse gas emissions worldwide.     2     Swapping out “high-emission” food and replacing it with “low-emission” food reduces the amount of greenhouse gases needed to grow, process, transport, distribute, prepare, consume and dispose of that food.

In each of four food groups — protein, mixed dishes, dairy and beverage — researchers looked at foods that disproportionately contribute to greenhouse gas emissions that cause global warming.     3     Finally, they calculated what the impact would be both for an individual’s carbon footprint and for the country’s if the dietary changes were made. By doing this, it will be pretty easy for people to adopt the new dishes because they will be pretty similar to what they are currently eating.

Top foods to swap out

USA TODAY asked if there is one specific food (or food group) that would be most recommended to be swapped out of.     4     Replacing beef with poultry or vegetarian items was particularly impactful, but other options include replacing juice with whole fruit and replacing dairy milk with nondairy milks like soy or almond milk.     5     Even replacing just one serving per day or one serving per week can add up to meaningful benefits.

A．If universally adopted, the recommended changes would lower the nation’s dietary carbon footprint.

B．The team then matched each of these environmentally unfriendly foods to a similar option with a far lower carbon footprint.

C．The good news is that there are many options for small changes to make to reduce your carbon footprint and improve your diet.

D．A drastic change in your diet isn’t necessary to make a significant difference.

E．You don’t have to make these changes all the time to make a difference.

F．This means that changing what we eat can reduce greenhouse gas and carbon pollution.

G．If you are a person who make the changes that we propose, you’re likely to see the benefits you want.

9 . Human activities are making the globe saltier, specifically in our soils, fresh water and air, according to a study released this week in the journal Nature Reviews Earth & Environment.

Salt pollution isn’t some flashy threat to our existence — like, say, a meteor hitting Earth — but the issue is gravely overlooked and is a “sleeping giant”, said Sujay Kaushal, lead author of the study. Over the past 50 years, salt have increased in streams and rivers as people have begun using and producing more salts. The team found that across the globe, about 2.5 billion acres of soil — an area about the size of the United States — have become saltier.

Most people think of salt as the white specks we put in our food or the salt in the oceans, chemically known as sodium chloride (NaCl). That sodium salt can also be found in detergents (去污剂), other household products and more, but there are many different salts, including calcium, magnesium and other ions used in additional products — and they’re all increasing in places where they don’t normally occur.

Salt is a natural and necessary component of Earth. The compound is brought to the surface slowly over long geological time scales, through natural processes such as weathering of sedimentary (沉积而成的) rocks. When exposed at the surface, the salt can mix with water, be transported into water or go into the air. Living organisms, from plants to people, take up small portions to help regulate daily functions. Excess salt hitches a ride with water molecules, entering soil and the oceans. But human activities have altered this normal salt cycle in recent decades, the team found. Agriculture, mining, construction, water and road treatment, and other industrial activities are increasing the salt in our ground, freshwater systems and air.

Before this study, scientists didn’t really know how much humans were changing salt concentrations around the globe. But the “magnitude to which we have altered one of Earth’s natural cycles is alarming,” said ecologist Bill Hintz, who was not involved in the research. He agreed with the study’s authors that these changes to the salt cycle are an existential threat to freshwater supplies.

1. The underlined word “flashy” in Paragraph 2 can best be replaced by ________.

A．instant

B．serious

C．damaged

D．unsolved

2. What can we infer from Paragraph 3 about salt?

A．People can only have access to sodium salt in daily life.

B．People intend to have a limited insight into salt.

C．Additional products are supposed to be banned.

D．Salts are increasing in the world scale.

3. What’s the normal salt cycle according to paragraph 4?

A．Forming as a compound — weathering of sedimentary rocks — consumed by living organisms

B．Coming into being in Earth naturally — being brought to the surface — combining with water — entering soil and oceans

C．Coming into being in Earth naturally — being transported to water and air — increased by human activities

D．Forming as a compound — removing excessive salt — entering soil and oceans

4. Which of the following words can best describe the study?

A．Inefficient.

B．Unreliable.

C．Brain-washing.

D．Ground-breaking.

10 . The Impact of Climate Change on Global Agriculture

Climate change has become a pressing issue in recent years, with its effects being felt across various sectors, including agriculture. Rising global temperatures, changing precipitation (rainfall) patterns, and increasingly frequent extreme weather events pose significant challenges to agricultural systems worldwide.

One of the main impacts of climate change on agriculture is crop yield reduction. Higher temperatures can decrease crop productivity, as certain crops have specific temperature requirements for optimal growth. Changes in rainfall patterns can lead to droughts or floods, both of which can negatively affect crop health and yield.

Additionally, the increase in extreme weather events such as hurricanes and heatwaves can cause extensive damage to crops and infrastructure (基础设施).

Climate change also interrupts the ecology of agricultural regions. Shifts in temperature and precipitation can affect the distribution of pests and diseases, leading to increased pest outbreaks and the spread of plant infections. This puts further pressure on farmers to adapt their practices and find alternative methods for pest control and crop protection

Furthermore, water scarcity (lack) is a growing concern in many agricultural regions as a result of climate change. Changes in precipitation (rainfall) patterns and increased evaporation (蒸发) rates contribute to reduced water availability for irrigation purposes. This can lead to water stress for plants and livestock, impacting their growth and productivity.

1. What is one of the main impacts of climate change on agriculture?

A．Reduction in crop yield	B．Improved crop health
C．Decreased water scarcity	D．Increased crop productivity

2. How can changes in rainfall affect agriculture?

A．Increase water availability for irrigation

B．Improve crop health and yield

C．Cause droughts or floods

D．Reduce the spread of pests and diseases

3. What are the consequences of changes in precipitation (rainfall) patterns and increased evaporation rates?

A．Increased water availability for irrigation	B．Water scarcity
C．Reduced pressure on farmers	D．Reduced water availability
