Humpback whales are well-known for their fascinating culture: These animals migrate thousands of miles every year, sing beautiful songs, leap from the water, and cooperate while hunting—creating bubble nets that trap their prey. Now, researchers have shed light on another aspect of whale behavior: Playing with kelp (海藻) they find floating in the ocean—moving it between their fins, rolling around with it, and, most intriguingly, wearing it atop their heads like a hat.
This behavior called kelping has been described in a new study as a "global phenomenon". There's no doubt kelping looks fun. But could it have another purpose? Olaf Meynecke, research fellow at Griffith University and co-author of the study, thinks so—especially considering that whales can keep it up for 30 to 40 minutes.
"What's particularly interesting about kelping is the way that humpbacks from different populations—in both the Northern and Southern Hemispheres—all prefer to wear seaweed on the top of their heads," says Meynecke. "They place kelp on their forehead in over half the recorded instances. Baleen species are believed to like having their heads scratched—gray whales are known for approaching whale-watching boats for a tickle (痒) on the nose. Because whales don't have hands to scratch themselves, like we do. Kelp is slippery and smooth. It's a very neat feeling and I can imagine a whale might enjoy that feeling too—like a massage."
"Whales might also be treating kelp like a cleansing face mask, as seaweed can reduce levels of bacteria. Rubbing kelp across their bodies may shed bacterial and viral growths to prevent them getting completely overgrown with skin infections," says Meynecke.
The study has caught the attention of researchers globally, and Meynecke's mail box has been flooded with mails from people who have also seen kelping. "Someone from Tahiti was like, ‘We see it all the time.'" he says. Now the phenomenon has been highlighted globally, which could lead to further research into the behavior, its benefits, and even if other marine species do it.
(1)、What does the phrase "shed light on" mean in Paragraph 1?A、Illustrate. B、Appreciate. C、Celebrate. D、Eliminate.(2)、What does Meynecke find about whales' kelping?A、It is a way to help them feel good. B、It can remove bacteria completely. C、It can be kept for more than 40 minutes. D、It is not preferred by various humpbacks.(3)、What will the follow-up study probably focus on?A、Explaining whales' kelping. B、Protecting other marine animals . C、Researching kelping's benefits. D、Exploring other species' kelping.(4)、What's the main idea of the text?A、Origin of whales' kelping. B、Reasons for whales' kelping C、Skills of whales' kelping. D、Ways of whales' kelping. -

At this zoo visitors move quickly to avoid the running elephants, look closely at the open mouth of a shark and pat friendly giraffes. Such thrills are possible at Australia's "Hologram (全息影像) Zoo", which opened earlier this year, and features 50 lifelike displays from dinosaurs to gorillas created by lasers.
"It's the world's most futuristic (极其现代的) animal theme park, using the hologram technology that has never been used anywhere else, says Bruce Dell, the chief executive of Axiom Holographics and creator of Hologram Zoo.
It is digital trickery, tricking the brain into seeing something that isn't really there.
"When we are projecting (投映) an object in the air, we need to make sure that it appears to be real because as people walk around it they are seeing it from all sorts of different angles. So, we use laser light to project these animals into the air," Bruce tells the BBC.
The hologram show uses a new "depth" technology that makes the animals seem big. The moving images are brought to life by a laser projector containing crystals that let simple sunglasses worn by guests separate fields of light.
Crucially, there's a device that knows where everyone in the room is, creating a tailored virtual experience. The hologram shows also come with sensory technology, allowing visitors to smell the flowers and trees.
Bruce Dell has recently held a hologram dinosaur show at the Australian Museum in Sydney. He sees an omnipresent future for holograms, including floating hamburgers and pizza at fast food restaurants, and virtual diamonds to attract buyers at jewellery shops.
"Often we talk about technology revolutions: television, cars, mobile phones, light bulbs, and the question is what is the next one? Well, the media has been telling us, science fiction has been telling us for years, the next one is the hologram revolution, having holographic things everywhere," he predicts.
(1)、 What is special about the Hologram Zoo?A、It is extremely dangerous. B、It applies a new technology. C、It houses a variety of animals. D、It is an old animal theme park.(2)、Why is laser light used to project animals into the air?A、To trick the brain. B、To enlarge their size. C、To make their images more lifelike. D、To offer visitors a new experience.(3)、What's Bruce Dell's attitude towards the future of holography?A、Doubtful. B、Uncertain. C、Optimistic. D、Uncaring.(4)、What's the author's purpose in writing the passage?A、To advertise the Hologram Zoo. B、To introduce a new technology. C、To promote the technology revolutions. D、To explain the working principle of holography. -

Carolyn R. Bertozzi, born in 1966, a Harvard University graduate, was among three winners of the Nobel Prize in chemistry for taking click chemistry "to a new dimension" by discovering how to use it in living cells. The technique enables scientists to precisely manipulate (操控) cells with chemical tools to learn how they behave, either when healthy or diseased.
Laura Kiessling, a professor of chemistry at MIT, said Bertozzi's work provided "a powerful new way" to monitor and separate molecules from cells in ways that weren't possible before. "It changed the way people think about doing science," she said. "There have been further advances, but they all build on her work."
"So many scientists use these reactions to monitor things in cells, even by people who aren't chemists," Kiessling said. "It's just become a tool that people can use broadly in many different fields."
Even though click chemistry is just starting to lead to therapeutic applications, scientists emphasize that Bertozzi's contributions to fundamental science shouldn't be minimized. Her work formed the cornerstone of a larger field called "bioorthogonal chemistry", a term she coined to reflect chemical reactions performed inside of living organism that don't disturb their normal functions.
During her college days, Bertozzi played keyboards in a band with Tom Morello. "That might be the one thing that I'm best-known for," she recalled. "We played college parties at Harvard and around the Boston area, and then he went off to become a superstar. And I wasn't talented the way he was. So I think I made the right choice to graduate school."
The Nobel Prize is a capstone to Bertozzi's dozens of research and teaching accolades (荣誉). She has received the MacArthur Fellowship, known as the "genius award". She will also receive the Wistar Institute's 2022 Helen Dean King award, which recognizes "outstanding women in biomedical research".
(1)、What can we learn about the technique of click chemistry?A、It shortens the time to detect cells. B、It helps to cure diseased cells. C、It is mainly applied in the field of cells. D、It increases the accuracy of manipulating cells.(2)、Why does the author mention Kiessling?A、To highlight how significant Bertozzi's finding is. B、To show that she disapproves of Bertozzi's finding. C、To explain why Bertozzi does research into click chemistry. D、To indicate that click chemistry can only be applied to limited fields.(3)、Which of the following best describes Bertozzi?A、Innovative and honest. B、Determined and tolerant. C、Inspiring and humorous. D、Expert and outstanding.(4)、What's the best title for the passage?A、A Winner of Nobel Prize B、The History of Nobel Prize C、A Technique to Manipulate Cells D、Secrets to a Scientist's Success -

The Surprise Encounter
Emma, a shy first- year student at Green Hills High, always kept to herself during lunch breaks. She preferred to sit alone under the big oak tree, reading a book or sketching in her notebook. One day, as she was about to settle down for lunch, she noticed a new student sitting on the bench next to hers.
The new student, Jenna, was reading a book with a serious look in her eyes. Emma couldn't help but steal a glance at the cover — it was a book she had read and loved deeply. Curiously, she hesitated for a moment before finally gathering the courage to speak.
"Hi, I couldn't help but notice you're reading The Curious Incident of the Dog in the Night- Time. I love that book too! " Emma said, her voice barely above a whisper.
Jenna looked up, surprised, and a smile spread across her face. "Really? That's amazing! I just started it and I'm already hooked. What did you think of it? "
Their conversation flowed effortlessly from there, and before they knew it, the lunch bell rang. Emma and Jenna exchanged a promise to continue their discussion later and went their separate (各自的) ways.
注意:1. 所续写短文的词数应为 150 左右;
2. 请按如下格式在答题卡的相应位置作答。
The next day, Emma arrived at the oak tree earlier than usual, holding her copy of the book and feeling a mix of excitement and nervousness.
……
As they went deeper into the book's stories, Emma found herself opening up more and more to Jenna.

Online English has become a common language for users from around the world. In the process, the language itself is changing. There are now thought to be some 4.5 billion web pages worldwide. Some language experts predict that within 10 years English will occupy the internet — but in forms very different to what we accept and recognize as English today.
That's because people who speak English as a second language already outnumber native speakers. And increasingly, they use it to communicate with other non-native speakers, particularly on the Internet where less attention is paid to grammar and spelling and users don't have to worry about their accent (口音).
Users of Facebook already socialize in a number of different "Englishes" including Indian English, Spanish English and Korean English. While these different styles have long existed within their cultures, they're now expanding and coming online. Technology companies are introducing newly-developed English words with products aimed at enabling users to add words that are not already in the English dictionary. And most large companies have English websites, while smaller businesses are learning that they need a common language — English — to reach global customers.
The increasing popularity of the internet allows more languages to develop quickly. "Most people actually speak several languages — it's less common to only speak one," says Mr. Munro. "English has taken its place as the world's common language, but it's not pushing out other languages." Instead, other languages are pushing their way into English, and in the process creating something new.
(1)、What does the text mainly talk about?A、There are now many different language styles. B、English is a common language around the world. C、English language is developing with the Internet. D、Smaller businesses are learning a common language.(2)、Which of the following is NOT true about online communication?A、Grammar is not so important. B、People need to spell accurately. C、People do not care about their accent. D、Most English-speakers are not native speakers.(3)、What can we infer from the text?A、We can only communicate online in English. B、Smaller businesses are not allowed to have English websites. C、It's impossible to find all the English words in the dictionary. D、Some technology companies start to publish English dictionaries.(4)、What can we learn from what Mr. Munro said?A、Other languages are enriching English. B、Chinese used to be the world's common language. C、English will become the only language in the world. D、One can't live well without speaking several languages.
