Growing up in a coastal town in San Francisco, Christian had a special love for the ocean and its creatures. He had always found joy in the rhythmic tides and the ocean waves against the shore. The salty wind and the cries of the seagulls (海鸥) had been like a comforting song to him during his childhood.

However, all these changed over the years. Every time he wandered along the familiar stretch of sand, his heart sank. The once charming beach was now littered with plastic bags, bottles and other wastes, a distinctive contrast to the natural beauty that had always absorbed him.

The sight was a painful reminder of the harm the locals were bringing to the very land where he was growing up. Christian felt a deep sense of loss and responsibility. Previously, he had seen the news reports about the severe effects of plastic pollution on the oceans, and the images of sea creatures stuck in plastic wastes haunted (萦绕于脑际) him.

Determined to make a change, Christian decided to take action. He knew he couldn’t solve this problem alone, but he could start something that might grow into a powerful movement. With the passion and belief of a young man who loved his ocean and his land deeply, he founded an organization called Waves of Change. The early days presented challenges in calling on volunteers.

He began by reaching out to the students in his school. He shared the shocking reality of the polluted beaches and the urgent need to reduce plastic litter. To his delight, gradually more and more schoolmates started showing interest in the organization and many were eager to join in the cause. They were all too familiar with the beauty of the ocean and were equally saddened by the damage they had witnessed. As high school students, Christian and other members properly allocates (分配) time to balance the cause and their academic work.

4 . Teachers worried about students turning in essays written by a popular artificial intelligence chatbot now have a new tool of their own.

Edward Tian, a computer science major at Princeton University, has built an App called GPTZero to detect whether a text is written by Chat GPT, which is a popular chatbot that has caused fears over its possibility for immoral uses in American academic circles. His motivation to create the computer program was to fight what he sees as an increase in AI plagiarism (剽窃). Since the release of ChatGPT in 2022, there have been reports of students using the language model to pass off AI-written assignments as their own. Many teachers have reached out to him after he released GPTZero, telling him about the positive results they’ve seen from testing it.

To determine whether an essay is written by a computer program, GPTZero uses two indicators: “confusion” and “burstiness (突发性)”. The first indicator measures the complexity of text; if GPTZero is confused by the text, then it has a high complexity and it’s more likely to be human-written. However, if the text is more familiar to GPTZero — because it’s been trained on such data — then it will have low complexity and therefore is more likely to be AI-generated. Besides, the second indicator compares the variations of sentences. Humans tend to write with greater burstiness, for example, with some longer or complex sentences alongside shorter ones. AI sentences tend to be more uniform.

In a demonstration video, Tian compared the App’s analysis of a story in The New Yorker and a Linked In post written by ChatGPT. It successfully distinguished writing between human and AI. However, GPTZero isn’t foolproof, as some users have reported when putting it to the test. He said he’s still working to improve the model’s accuracy.

Tian is not opposed to the use of AI tools like ChatGPT. GPTZero is “not meant to be a tool to stop these technologies from being used,” he said. “But with any new technologies, we need to be able to adopt it responsibly and we need to have protections.”

1. What have some students done since ChatGPT was released?

A．They have built language models from ChatGPT.

B．They have copied AI-written text from ChatGPT

C．They have accessed their assignments through ChatGPT.

D．They have passed their writing exams through ChatGPT.

2. What can be inferred about the two indicators of GPTZero?

A．The more uniform the text is, the more likely it is to be AI-generated.

B．The less complex the text is, the more likely it is to be human-written.

C．GPTZero sometimes confuses human-written texts with AI-generated texts.

D．GPTZero is more familiar with human-written texts than with AI-generated texts.

3. What does the underlined word “foolproof” mean in the fourth paragraph?

A．User-friendly.	B．Time-efficient.
C．Perfectly legal.	D．Completely reliable.

4. What maybe Tian’s attitude to the use of AI tools?

A．Favorable.

B．Disapproving.

C．Objective.

D．Ambiguous.

5 . 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 November 2023, China launched a three-year action plan to promote the use of bamboo as a replacement     1     plastic. Actually, I’ve been using bamboo products more often over the years.

6 . World’s Best Spicy Foods

When it comes to the world’s best spicy dishes, we have some of the world’s hottest peppers to thank. The following spicy dishes from around the world bring the heat in the most delicious way.

Piri piri chicken, Mozambique

The Portuguese introduced this spicy dish into Mozambique as far back as the 15th century, when they mixed African peppers with European ingredients. And it’s the red pepper that brings the spiciness to this complex, layered and delicious dish. The dish is also popular in Namibia and South Africa.

Sichuan hot pot, China

The joy of this dish is not only the delightful warming ingredients of the Sichuan peppercorns, but the fact that you can cook exactly what you like in the spicy soup. Duck, seafood, chicken, pork, lamb and seasonal vegetables are all fair game for throwing into the pot to boil in a soup made with Sichuan peppercorns and dried Sichuan peppers.

Som tam, Thailand

From northeastern Thailand, this fresh and spicy salad is a main dish at Thai restaurants around the world. Som tam turns to green papaya(木瓜) for its main ingredient. The papaya is then put with long beans or green beans and a mix of flavorful Asian essentials that include dried shrimp(虾) and fish sauce among other ingredients. Thai peppers give the salad its necessary kick.

Aguachile, Mexico

This raw marinated(腌制) shrimp dish from the western Mexico tastes as good as it looks. Tiny but powerful peppers, grown throughout Mexico, make the spicy magic happen in the aguachile, which means “pepper water” . Marinate the raw shrimp with ingredients including lime(酸橙) juice, red onion and cucumber and enjoy with fried corn pancakes.

1. How does piri piri chicken differ from the other three foods?

A．It goes with vegetables.	B．It uses a variety of ingredients.
C．It is flavored with red peppers.	D．It originated in another country.

2. Which dish gives you the freedom to choose the main ingredients?

A．Piri piri chicken, Mozambique.	B．Sichuan hot pot, China.
C．Som tam, Thailand.	D．Aguachile, Mexico.

3. What do som tam and aguachile have in common?

A．They are raw foods.	B．They have a long history.
C．They are served with pancakes.	D．Shrimp is their main ingredient.

7 . Food polluted with fungi (真菌) can be an inconvenience at best and life-threatening at worst. But new research shows that removing just one protein can leave some fungal toxins (毒素) high and dry, and that’s potentially good news for food safety.

Some fungi produce toxic chemicals called mycotoxins that not only ruin food such as grains but can also make us sick. “It is a silent enemy,” said fungal researcher Ozgur Bayram of Maynooth University in Ireland, as most people don’t notice when foods like corn or wheat are ruined.

For years, researchers have known that some fungi produce these toxins, but didn’t know all the detail. Now, Bayram and his colleagues have identified a group of proteins responsible for turning on the production of mycotoxins. Genetically engineering the fungus to remove even just one of the proteins prevents the toxins from being made, the researchers reported in the September 23 issue of Nucleic Acids Research.

“The newly identified proteins act like a keystarting a car,” Bayram said. “The researchers wanted to figure out how to remove the key and prevent the starting signal from going through, meaning that no toxins would be made in the first place.”

Bayram and his team identified the proteins in a kind of fungus named A. nidulans, revealing that four proteins come together to make the key. The researchers genetically engineered the fungus to delete each protein in turn. When any of the four proteins are missing, the key does not start mycotoxin ignition(点火装置), the team found.

Fungi and fungi-like organisms are estimated to ruin a third of the world’s food crops each year. If that contamination could be prevented, Bayram estimates the saved food would be enough to feed 800 million people in 2024.

The new research is a good start, but it will still be a challenge to try to understand how this can be operationalized for agricultural purposes. “It’s difficult to apply the technique, and getting US regulatory agencies to approve the use of a genetically modified fungus on key food crops might be difficult,” said Felicia Wu a food safety expert.

1. Why is the mycotoxin called “a silent enemy”?

A．It is hard to be proved.	B．It tends to be unnoticed.
C．Its protein is harmful.	D．Its damage is incurable.

3. What is one difficulty according to Felicia Wu?

A．Changing the genes of fungus.	B．Putting the technique to practical use.
C．Enlarging the size of farmland.	D．Using genetically modified food.

4. What is the main idea of the text?

A．Many crops are ruined by fungi each year.	B．Fungi bring great harm to people’s health.
C．Deleting a protein can stop toxin production.	D．Researchers found new proteins producing toxins.
