Do you like to taste food at stores before you buy it Or stop in the fitting room to try on clothes before paying for them What if you could do the same for travel Well, Kayak is making it happen with the new Kayak VR, an app that helps travellers to “visit” a place before booking it.
Kayak calls the new VR app a way to “test drive” a city from home, both to choose a place and to find out what to see once you get there. The app brings visual (视觉的) information and an audio (声音的) tour of different places together. As well as visiting local hotspots (当地热点), users can go around in hotels too.
Kayak VR offers a few different ways to travel around. For example, travellers can use a computer to move around the scene while listening to an audio tour. Inside Kayak VR, information on the screen will tell viewers what landmark (地标) they are looking at, as well as details. The app is the travel company’s first move into VR. It now offers information about two cities: Venice in Italy, and Kathmandu in Nepal. If it sees success, more cities will be included.
The company doesn’t mean to take the place of a real visit with their app. “Kayak VR is just a study tool that lets you try a city on for size before booking. Nothing is better than actually touching down in a new city and feeling it for yourself.”

On January 20, 2025, a Chinese tech company named DeepSeek made a new AI called DeepSeek-R1. This smart program can solve math problems, write code, and answer questions like top models such as OpenAI’s GPT-4o, but it costs much less to build. The team spent only $5.58 million and used 2,048 computer chips (芯片) for two months. This shows that good ideas can beat big money.
DeepSeek-R1 learns by trying many times and getting better, like how students practice maths. Other AIs need lots of prepared examples, but R1 improves by itself. For example, in a world math test, it got 79.8% right, a little higher than OpenAI’s model. A simple kind of R1 can even run on cheap computers, helping schools and small companies.
DeepSeek-R1 is free to use and change. On its first day online, over 19,000 programmers all over the world started projects to study it. A German scientist said experiments (实验) with R1 cost $10 instead of $300 with other AIs. Even Meta (a famous U. S. tech company) top scientist said, “This kind of free AI could change the world.”
US tech companies are worried. Meta plans to spend $65 billion more on AI research. Experts say China is catching up fast. A report in Nature magazine called R1 a “big step forward”, proving (证明) that smart ideas beat expensive tools.
As a DeepSeek engineer said, “We want AI to be a friend, not something only rich people can use.” With R1, China shows the world that great things come from new ideas and hard work, not just money.

C．In a science and technology magazine. D．In a fashion newspaper.
D
Have you ever imagined being able to communicate with your pets at home and let them understand everything you say It sounds too good to be true, but scientists have started using AI to help communicate with animals.
AI allows humans to use technology to watch and understand the sounds and signals (信号) animals use, so we can try to speak back to them. By decoding (解码) recordings of animals talking to one another, humans can communicate in their language, and it could be better than teaching them to use human sign language.
Scientist Karen Bakker said that AI is already helping humans communicate with bats (蝙蝠) and bees. This could change what we know about nature and the relationships between humans and animals.
Karen explained how scientist Yossi Yovel had used recordings and AI to understand bats. “Bats argue for food, they communicate differently between genders (性别); they have their names, or ‘signature calls’ (专属名号),” she said. “But unlike human mothers who raise the pitch (声调) of their voices when talking to babies, bat mothers lower the pitch.”
“When bees ‘speak’ to one another, they use body movements and the sounds to communicate,” Karen said. She said scientists now know how bees say things such as “be quiet” and “stop”. Scientist Tim Landgraf even created a robot bee that entered a hive (蜂房) and was able to communicate with the bees when it wanted them to stop doing something or fly.
Perhaps soon, humans will be able to communicate with more animals.
26．How does the writer start the passage
A．By telling a story. B．By listing facts.
C．By asking a question. D．By giving examples.
27．How do scientists communicate with animals using AI
A．By decoding the recordings of animals’ communication.
B．By teaching animals human sign language.
C．By changing the relationship between humans and animals.
D．By learning animals’ language from books.
28．What can we know about bats and bees according to the passage
A．Bats have special names for each other.
B．Bats lower their voices when talking to each other.
C．Bees work as a team and never fight for food.
D．Bees use different sounds and movements when talking to different genders.
29．Why is the example of the robot bee mentioned
A．To show that bees can follow humans’ orders easily.
B．To explain how bees use body movements to communicate.
C．To prove that AI can help humans communicate back to animals.
D．To introduce the new technology of creating robot animals.
30．What’s the best title of the passage
A．The Use of AI Technology

Today, AI humans are popular at home and abroad (国内外).
31 They can imitate real people’s voices and movements and even copy their personalities. But what else can they do And what can only be done by humans but not AI
32 They can be idols (偶像), vloggers (视频博主), reporters and more. For example, China Daily has its own digital reporter, Yuanxi. She can speak English and process (处理) data fast. This can help the newsroom work faster.
In February 2022, a Chinese tech company showed its first digital idol Xi Jiajia. 33 During China Fashion Week in September 2022, Xi Jiajia became famous in an online virtual fashion show (虚拟时装秀). On January 28, 2025, a special performance called Yang BOT amazed audiences (观众) at the CCTV Spring Festival Gala. And it also surprised people all over the world.
“Virtual idols could do something that people cannot do in the real world, such as time travel,” said Liu Qian. 34 They can appear to be in different places and from different times in history.
But AI humans have disadvantages. Take Yuanxi as an example. She still doesn’t have much human touch or high EQs. 35 What’s more, virtual people can’t team up and communicate with others in real time.
As Yuanxi wrote, “Virtual employees (雇员) show the power of AI but they are not a replacement for traditional human employees.”
A．AI humans now can be like real people.
B．Digital humans today appear in many ways.
C．Liu took the digital tour guides as an example.
D．AI can copy your character and show it to other people.
E．Virtual humans can have their own way of teaching people.

Zhang Qiang, a researcher who has been in the AI field for over ten years, never expected his work would connect with jiandu-China’s 3,000-year-old bamboo and wooden slips. Together with his team, Zhang developed DeepJiandu. It is the world’s first large-scale data set (大规模数据集) designed to recognize (识别) characters of Chinese relics (文物).
Before DeepJiandu appeared, researchers spent too much time recognizing jiandu characters. By scanning over 40,000 jiandu samples (样本), DeepJiandu can provide 7,416 pictures. This can help researchers look for jiandu research methods. Zhang’s team also studied many different samples and created nearly 100,000 notes by using DeepJiandu. These notes can allow beginners to learn about ancient Chinese writing and history better.
Today, this technology is used not only for scientific research but also as an important part of museums. For example, to help visitors learn about the interesting stories behind jiandu, the Changsha Jiandu Museum in Hunan Province developed an AR picture book. By scanning the QR codes (二维码) on book pages, visitors can learn historical facts such as life tips for people in ancient times. Meanwhile, two AI robots named “Little Jian” and “Little Du” are also used at the Gansu Jiandu Museum to provide guiding services for visitors.
“Using technology on jiandu not only makes the relics more interesting but also shows how China is mixing history with modern creativity,”said Zhu Jianjun, director of the Gansu Jiandu Museum.

On January 20, 2025, a Chinese tech company named DeepSeek made a new AI called DeepSeek-R1. This smart program can solve math problems, write code, and answer questions like top models such as OpenAI’s GPT-4o, but it costs much less to build. The team spent only $5.58 million and used 2,048 computer chips (芯片) for two months. This shows that good ideas can beat big money.
DeepSeek-R1 learns by trying many times and getting better, like how students practice maths. Other AIs need lots of prepared examples, but R1 improves by itself. For example, in a world math test, it got 79.8% right, a little higher than OpenAI’s model. A simple kind of R1 can even run on cheap computers, helping schools and small companies.
DeepSeek-R1 is free to use and change. On its first day online, over 19,000 programmers all over the world started projects to study it. A German scientist said experiments (实验) with R1 cost $10 instead of $300 with other AIs. Even Meta (a famous U. S. tech company) top scientist said, “This kind of free AI could change the world.”
US tech companies are worried. Meta plans to spend $65 billion more on AI research. Experts say China is catching up fast. A report in Nature magazine called R1 a “big step forward”, proving (证明) that smart ideas beat expensive tools.
As a DeepSeek engineer said, “We want AI to be a friend, not something only rich people can use.” With R1, China shows the world that great things come from new ideas and hard work, not just money.
21．How does the writer write Paragraph 1

Have you ever imagined being able to communicate with your pets at home and let them understand everything you say It sounds too good to be true, but scientists have started using AI to help communicate with animals.
AI allows humans to use technology to watch and understand the sounds and signals (信号) animals use, so we can try to speak back to them. By decoding (解码) recordings of animals talking to one another, humans can communicate in their language, and it could be better than teaching them to use human sign language.
Scientist Karen Bakker said that AI is already helping humans communicate with bats (蝙蝠) and bees. This could change what we know about nature and the relationships between humans and animals.
Karen explained how scientist Yossi Yovel had used recordings and AI to understand bats. “Bats argue for food, they communicate differently between genders (性别); they have their names, or ‘signature calls’ (专属名号),” she said. “But unlike human mothers who raise the pitch (声调) of their voices when talking to babies, bat mothers lower the pitch.”
“When bees ‘speak’ to one another, they use body movements and the sounds to communicate,” Karen said. She said scientists now know how bees say things such as “be quiet” and “stop”. Scientist Tim Landgraf even created a robot bee that entered a hive (蜂房) and was able to communicate with the bees when it wanted them to stop doing something or fly.
Perhaps soon, humans will be able to communicate with more animals.
26．How does the writer start the passage
A．By telling a story. B．By listing facts.
C．By asking a question. D．By giving examples.
27．How do scientists communicate with animals using AI
A．By decoding the recordings of animals’ communication.
B．By teaching animals human sign language.
C．By changing the relationship between humans and animals.
D．By learning animals’ language from books.
28．What can we know about bats and bees according to the passage
A．Bats have special names for each other.
B．Bats lower their voices when talking to each other.
C．Bees work as a team and never fight for food.
D．Bees use different sounds and movements when talking to different genders.
29．Why is the example of the robot bee mentioned
A．To show that bees can follow humans’ orders easily.
B．To explain how bees use body movements to communicate.
C．To prove that AI can help humans communicate back to animals.
D．To introduce the new technology of creating robot animals.
30．What’s the best title of the passage

Zhang Qiang, a researcher who has been in the AI field for over ten years, never expected his work would connect with jiandu-China’s 3,000-year-old bamboo and wooden slips. Together with his team, Zhang developed DeepJiandu. It is the world’s first large-scale data set (大规模数据集) designed to recognize (识别) characters of Chinese relics (文物).
Before DeepJiandu appeared, researchers spent too much time recognizing jiandu characters. By scanning over 40,000 jiandu samples (样本), DeepJiandu can provide 7,416 pictures. This can help researchers look for jiandu research methods. Zhang’s team also studied many different samples and created nearly 100,000 notes by using DeepJiandu. These notes can allow beginners to learn about ancient Chinese writing and history better.
Today, this technology is used not only for scientific research but also as an important part of museums. For example, to help visitors learn about the interesting stories behind jiandu, the Changsha Jiandu Museum in Hunan Province developed an AR picture book. By scanning the QR codes (二维码) on book pages, visitors can learn historical facts such as life tips for people in ancient times. Meanwhile, two AI robots named “Little Jian” and “Little Du” are also used at the Gansu Jiandu Museum to provide guiding services for visitors.
“Using technology on jiandu not only makes the relics more interesting but also shows how China is mixing history with modern creativity,”said Zhu Jianjun, director of the Gansu Jiandu Museum.

11．篇章结构题。根据第1段“Do you like to taste food at stores before you buy it Or stop in the fitting room to try on clothes before paying for them What if you could do the same for travel ”可知，作者通过连续提出与日常生活相关的问题来引出文章主题。故选B。
12．细节理解题。根据第4段“Kayak VR is just a study tool that lets you try a city on for size before booking. Nothing is better than actually touching down in a new city”可知，Kayak VR只是一个供你出行前研究的工具，真正的预定（booking）和实际抵达（touching down）还是要靠用户自己。因此，它不能为用户预定航班和酒店。故选C。

My Internet Life
The internet has become an important part of my daily life. I often use it to search for information and watch educational videos.
The internet brings me many benefits. It makes studying much easier. However, sometimes I spend too much time watching funny videos, which is not good for my eyes or my study time.
To use the internet wisely, I set a time limit for myself—only one hour on school days. I never share my personal information with strangers online.
In short, the internet is very useful if we use it in the right way. Let’s enjoy its benefits while staying safe and healthy.
