1 . There are robot cleaners and robot mops to help us around the house, so why not a robot to build our houses? Wait no longer. Now there is a set of electronics to do just that, build a house from scratch, and fast.

Forget weeks to find a builder and months for house construction; a machine developed in the United States can build a 232 sqm house layer by layer in a single day. University of Southern California’s Professor Behrokh Khoshnevis has designed the giant robot that replaces construction workers with a mouth on an arm of crane, which spits out concrete and can quickly build a house according to a computer pattern. The technology, known as Contour (轮廓) Crafting, could revolutionise the construction industry.

Contour Crafting could greatly decrease the cost of homeowning, making it possible for millions of displaced people to get on the property ladder. It could even be used in disaster relief areas to build emergency and replacement housing. As Prof. Khoshnevis points out, if we look around almost everything is made automatically these days—shoes, clothes, home appliances, cars. The only thing that is still built by hand are buildings.

The Contour Crafting system is a robot that automates age-old tools normally used by hand. These are applied by a robotic crane that builds a three-dimensional object. The nature of the technology means it will also be possible to create curved walls and architecture that is both “exotic (异国情调的) and beautiful” according to Prof Khoshnevis. As a result, it could be ideal to print out expensive houses according to customers’ demands.

Furthermore, Prof. Khoshnevis believes that the technology could be applied beyond our planet. “Contour Crafting technology has the potential to build safe, reliable, and affordable structures, habitats, laboratories, and other facilities on the moon and Mars before the arrival of human beings,” his website reads.

According to the International Labour Organisation, construction employs nearly 110 million people worldwide and “plays a major role in fighting the high levels of unemployment and in absorbing extra labour from the rural areas”. What the implications are for builders is, of course, a major concern. But Khoshnevis says “the reality is that a lot of new jobs can be created in this field as well”. Instead of building the house, workmen are used to maintain the machine.

2 . Before children learn to read, they need to have a good understanding of basic words and what they mean. And while that may sound a bit overwhelming (令人不知所措的), there are very easy ways that you can build a preschooler’s vocabulary.

Visit the Library

If you are looking for a great place to start building your preschooler’s vocabulary and early reading skills, look no further than your local library.     1     Children’s libraries often have fun activities, which will expose them to new words and give them an opportunity to socialize.

Teach and Strengthen the Alphabet (字母表)

    2     The bonus: it’s a great way to keep your preschooler busy on long car rides,or while waiting in lines. You can also play games using the alphabet, where you name items that start with letters in alphabetical order.

Use Descriptive Words

When it comes to increasing your child’s vocabulary, more is better.     3     For example, when describing a fabric pattern, try using words such as unusual, relaxing, or creative. By using them in the proper context (语境), they become understandable.

Make Labels

If you want your preschooler to learn more words, then make it easy.     4    Use a label maker to name commonly used items so they learn to recognize what the word looks like.

Read Aloud Together

Reading aloud is a great way to expose your preschooler to new words. Together you can work out what they mean by using context-the other words or pictures that might be on the page.     5    

A．In such cases, planning is required.

B．In addition to saying them often, show them too.

C．If you aren’t sure what to do, ask the librarian for help.

D．It is also a wonderful way to spend quality time with them.

E．The more words your children hear, the more they will learn.

F．As you can see, increasing your child’s vocabulary isn’t difficult.

G．Singing the ABC song provides children with some strong support.

3 . A planet that suffers 475 C beneath a thick acid atmosphere may be the last place you'd expect alien (外星的) life in our solar system. But one NASA scientist claims that extraterrestrials (天外来客) are most likely hiding on Venus amid conditions that are unbearable for humans. The new theory was put forward by the research scientist Dr Michelle Thaller. She says that possible signs of life have already been seen within the carbon-dioxide filled atmosphere, adding that she was absolutely certain that life exists somewhere.

Venus is often described as Earth's twin due to its similar size and structure. But their conditions couldn't be further apart, as astronomers believe it would be impossible for humans to exist on Venus. Positioned 67 million miles from the Sun, Venus is the hottest planet in our solar system, suffering temperatures that can even melt lead. Its atmosphere also adds to the uninhabitable situation.

Despite this, scientists have long debated whether Venus' clouds may host microbial (微生物的) life forms that can survive. Many scientists think that photosynthesis (光合作用) is possible on the planet's surface as Venus receives enough solar energy to pass through its thick clouds.

However, Professor Dominic Papineau, a biologist at the University College of London, believes Dr Thaller's views are “difficult to realistically assume”. He explained, “For life-related chemical reactions to take place, liquid water is necessary. Hence, to find extraterrestrial life, we need to find liquid water, and to find extraterrestrial fossils requires looking for special rocks that were associated with liquid water in the past.”

This makes life on Venus today difficult to realistically assume, because its surface is too hot, although Venus might have had liquid water in its past. Even still, both Professor Papineau and Dr Thaller agree that the icy moons of our solar system could also be sites of potential microbial life. NASA suggests there are 290 “traditional moons” in our solar system-excluding 462 smaller minor planets.

4 . A recent study conducted by the Massachusetts Institute of Technology (MIT) has discovered that river erosion (侵蚀) can lead to increased biodiversity in areas with minimal tectonic (地壳构造的) activity. The researchers focused their attention on the Tennessee River Basin and examined how the erosion of various rock types by the river had led to the separation and diversification of a type of fish called the greenfin darter. As time passed, these separate fish populations evolved into distinct families with genetic differences.

Scientist Thomas Near observed that the greenfin darter was exclusively found in the southern half of the Tennessee River Basin. The researchers analyzed the genes of each fish in Near’s data set and constructed an evolutionary tree. This tree helped them comprehend the evolution and differences of the greenfin darter species. They discovered that the fish within the same branch of the river were more closely related to each other than to the fish in other branches.

This study provides evidence that river erosion significantly impacts biodiversity in regions with low tectonic activity. It illustrates how changes in the landscape caused by river erosion can lead to the division and diversification of species over time, even in peaceful environments. These findings enhance our understanding of the mechanisms (机制) that drive biodiversity and evolution, even in areas that are not typically associated with intense tectonic activity.

Subsequently, the team discovered a strong correlation between the habitats of the greenfin darter and the type of rocks present. The southern half of the Tennessee River Basin consists of hard, tightly packed rocks, resulting in turbulent (湍急的) waves in the rivers that flow through it. This characteristic may be favored by the greenfin darter. As a result, the team assumed whether the distribution of greenfin darter habitats had been influenced by the changing rock types, as the rivers eroded the land over time. To test this assumption, the researchers developed a simulation model. Remarkably, the results confirmed their assumption.

1. What is new about the MIT study?

A．It finds river erosion can enhance biodiversity.

B．It further proves the mechanisms of river erosion.

C．It proves the geographical features of biodiversity.

3. How did Near help the researchers reach their conclusion?

A．By creating an evolutionary tree of the fish.

B．By offering the fish’s genetic data.

C．By reasoning out the time the fish evolve and separate.

D．By analyzing the genetic similarity between different fish.

4. What is the best title for the text?

A．River Erosion Can Shape Fish Evolution	B．Genetic Change in the Greenfin Darter

5 . Yu Zeling, an award-winning master of paper cutting, fills her studio with cutouts of animals, people, and scenes that are so vivid that they seem to leap from the walls. Her art covers village life in Ansai, a rural district in Shaanxi Province.

Ms. Yu came to paper cutting in the late 1970s as naturally as she breathed the earthy air.“We were very poor, and when it was time to celebrate the New Year, we all put paper-cuts on the windows to decorate our houses,” she says, recalling the holiday at her childhood home. Ms. Yu and others are working to keep the folk art alive, even as it evolves away from its roots as adornment for farmhouses.

The art originated in China in the centuries after paper was invented in A.D.105. Full of auspicious (吉利的) symbols from daily life, the decorations represented good weather, many offspring, long life, wealth, and happiness.

Using newspaper, Ms. Yu first practiced cutting the image of a Chinese national flag that she saw in a school textbook. She cut it 100 times before she was satisfied. Then her aunt took over, introducing her to increasingly complicated traditional themes.

Ms. Yu was later invited to train in the Ansai's Cultural Center. After years of training,Ms.Yu became a master in her own right, winning one award after another. Her works are on display in museums. But she's humble about her achievements. “I was, and still am, a farmer,” she says with a smile.

Hoping to carry on and grow the folk art, Ms. Yu volunteers to teach at free community training sessions. Paper cutting is also taught in Ansai’s public schools. Ms. Yu is aware of the need to go beyond protecting traditions and embrace new paper-cut experiments.

A．Celebration.

B．Symbol.

C．Invention.

D．Decoration.

2. What can be learned about paper cutting from the text?

A．It has cultural value.	B．It features animals.

C．An introduction to a paper cutting master.

D．The direction of a traditional paper cutting.

6 . As the second largest city of the Republic of Korea, Busan draws global attention. Here are some routes for visitors to have fun.

The First Route

Start off at the Haeundae Beach, where you can take a walk, sip a coffee, or try local fishcakes before heading up to BUSAN X the SKY. This observatory occupies the top floors of the city’s highest structure, where you’l1 be attracted by the wonderful urban views. You can also visit the old Haedong Yonggunsa Temple along the route.

The Second Route

With its popular Songdo Cable Car moving quickly over the water to a park, this route offers amazing views of the city’s traditional core. It’s just a quick taxi to the Yeongdo Island, home to some of Busan’s oldest neighborhoods, including the Huinnyeoul Culture Village. Overlooking the water, the whole picture that you can see is arguably the most romantic scene.

The Third Route

As a port city, you should head to the old harbor district of Nampo-dong to find its real charm. This is where you’ll find the Jagalchi Market, the open-air seafood market that’s not only a strong wave to the senses but also the city’s living and beating heart. Walk along its gathering as you see fresh seafood from the sea, along with the vendors (摊贩) who sell it all.

The Fourth Route

Shinsegae Centum City is not far from the Gwangalli Beach, a crowded area of sand,cafes, and eateries looking out across the water to the Gwangan Bridge. There will be a cool drone (无人机) show on Saturday in the evening of a hot summer and a fireworks festival in November.

7 . “Anxiety.” The very word invites discomfort. Its effects—shortness of breath, pounding heart, muscle tension—are outright upsetting. But, as a clinician, I find that we tend to miss out on many valuable opportunities presented by this human emotion. In and of itself, anxiety is not deadly, nor is it a disease. Quite the contrary: it is an indicator of brain and sensory health. Once we accept that it is a normal, though uncomfortable, part of life, we can use it to help us.

We all know working out at the gym is hard. By nature, a “good workout” is uncomfortable, since it involves pushing our physical strength past what we can easily do. The sweet spot of exercise is always a somewhat challenging experience. Similarly, if you want to be emotionally stronger, you need to face some tension. For example, one effective treatment for fear is exposure therapy (疗法), which involves gradually encountering things that make one anxious, reducing fear over time.

Humans are social creatures. When my patients learn to open up to their partners about their anxieties, they almost always report a greater sense of emotional closeness. Also, as international relationship expert Sue Johnson teaches, when we express our need for connection during challenging moments (e.g., “I’m having a hard time right now and could really use your support”), it creates greater connection and turns our anxiety into love.

From time to time, we find ourselves at the end of our rope. Our responsibilities pile up, our resources break down, and we feel uncomfortably anxious—what we’re experiencing is called stress. Simply put, the demands placed upon us outweigh our available resources, just like a set of scales (天平) going out of balance. Focusing on work and pretending everything is OK only leads to disastrous results. Medical treatment for stress may function for a while, but it tends to make things worse in the long run. The only solution to deal with stress is to do the mathematics to balance the scales.

1. What does the author say about anxiety?

A．It is an invitation to diseases.

B．It indicates stable mental health.

C．It costs us many valuable chances.

D．It is a natural emotional expression.

2. Why does the author mention “good workout” in paragraph 2?

A．To prove how exercise influences emotions.

B．To suggest an effective way to challenge limits.

3. What is paragraph 3 mainly about?

A．The key to closeness is partners’ support.

B．Sharing anxieties improves relationships.

C．Humans are defined by their social nature.

D．Expressing feelings keeps us off anxieties.

4. According to the last paragraph, how can we deal with stress?

A．Devote more energy to our work.

B．Increase resources available to us.

C．Seek professional medical treatment.

D．Master advanced mathematical skills.

8 .

9 . The first animal Tracey Parsons rescued was a baby bird she found jumping in and out of the road. It had lost its mother. Parsons was seven. She kept it in her bedroom, where it flew around the room. She went to the library to learn how to feed it. The bird started following her around. In the morning it would fly up to her bed and sing beautiful songs. “I’ll never forget it,” she says.

Parsons, who is now 35 and runs a clothes shop in Blackheath, London, doesn’t know how many animals she’s saved since then. Thousands, she estimates. “I like animals,” she says, “because they’re pure and reflect the beauty of nature. And they don’t have their own voices, so someone has to be their voice.”

Any time an injured bird or animal is found in the area, odds are it will find its way to Parsons’ home. People bring them to her front door all the time. Around Blackheath, people know Parsons as “the bird lady”. The local farmers’ market donates scraps (剩饭) for her to feed the ducklings.

She spends thousands of pounds a year on feed and medication. Once the animals are rehabilitated (康复), Parsons releases them into the wild or takes them to wildlife sanctuaries (保护区) if they’re not able to live independently.

“I’ve known Tracey for more than 10 years,” says her friend Diane Blackwell. “She paddles (划船) into freezing pond water to rescue ducklings. She’s rushed to my place to rescue a badly injured fox at 10 pm. She doesn’t have an off switch for her rescue work.”

When asked which animals stand out in her three-decade-long career as a wildlife rehabber, Parsons tells a seemingly unbelievable story. One day in 2019, Parsons was at her shop. When she opened the curtain she saw an injured fox. It ran away, but returned the next day, and every day after that. He’d jump in her lap, and follow her around. People think foxes are aggressive (富于攻击性的), but that’s not true, she says. “They’re adorable, loving creatures.”

1. What can we learn about Parsons’ rescue attempt at age seven?

A．She found it challenging and dangerous.

B．She found a dying duckling outside her room.

C．She regarded it as a memorable experience.

D．She brought a baby bird to a wildlife sanctuary.

2. What do Parsons’ words in paragraph 2 show?

A．She wants to protect animals.

B．Animals can recognize human voices.

C．Every animal has its own unique voice.

D．She thinks wild animals may threaten humans.

3. What does Blackwell say about Parsons?

A．She has devoted herself to saving animals.	B．She is supported by local people.
C．She feels tired from her work.	D．She cares little about her friends.

4. What made the fox unique in Parsons’ animal rescue career?

A．It was badly injured.	B．It was a rare species.
C．It was friendly to her.	D．It was found in her shop.

10 . Ecofriendly replacement products for single-use plastics are appearing everywhere. But have you heard of edible (可食性的) straws? Now EQUO, a new eco-friendly company in Vietnam has come up with a natural edible solution to plastic or paper straws.

The edible straws are completely plastic free, nontoxic, chemical free, and 100 percent biodegradable according to a company press release.

“It’s well known that plastic straws are harmful to the environment. Most of the 500 million used every day in America end up in oceans where they pollute water and harm marine life. Currently over eight billion straws pollute the world’s beaches,” said Marina Tran-Vu in the press release. “Although there are some plastic and paper straw alternatives on the market, most are environmentally harmful, and we were also unsatisfied with the quality and lasting of paper straws.”

All of the materials are locally from regions that support sustainable farming according to the company’s website and they struggle to have zero-net influence by” using the power of mother nature”. The name of the company was created by combining “ECO” — meaning environmentally friendly — with “STATUS QUO” — meaning the existent state. EQU stands for creating products that have minimal influence on the environment. The company was first shown on Kickstarter on May 18 and hit their funding goal in only 30 days.

Many countries are banning single-use plastics. The EU banned 10 single-use plastic products including straws that will take effect in 2021. Other items that will no longer be made of plastic include cutlery (餐具), and balloon sticks. These 10 items make up a large percentage of ocean waste that harms marine life.

So do your part, use biodegradable cutlery — you can carry your own , edible straws, and reusable water or coffee cups. These small items can contribute to reducing plastic waste.

1. What is the third paragraph mainly about?

A．The popularity of plastic straws.
