It was a hot day. The sun scorched (炙烤) down and everywhere you looked, you could see the heat waves blowing above the sand. John rolled over, realizing that half of his body was well and truly burnt. He had not meant to sleep in the sun but the heat and late nights studying for his examinations made him miserable. Stretching, he got to his feet, picked up his surfboard and looked around. The beach, which had earlier been crowded in the sun, was now comparatively empty. Seagulls flew down to clean up the food of people’s picnic lunches.
The ice-cream van had gone, and so were the lifeguards who were doing first aid on the beach. John looked up to where the sun was and estimated it was about five o’clock. Time to head home. It was “Mum’s Kitchen Rule” that had him moving homewards. If he did not get home in time for dinner, he would go hungry. Wandering along the water’s edge, he happened to glance out to sea. What made him look up at that particular moment, he never knew, but it was the right time for the swimmer he spotted. His hand was up, signaling distress (险情) and he was calling out something.
Quickly John glanced around the beach — no one else was close enough to help the man, and crucially, no one had noticed. Cupping his hands to his mouth, he shouted “Help” to get the attention of other people on the beach. Someone waved back to him and John pointed to the swimmer. “Get help,” he shouted. Then without hesitation, he jumped into the sea with his surfboard. John was a strong swimmer and had a good skill for distance swimming. His coach had tried hard to persuade him to go into competitions but he was not interested.

6 . Artificial intelligence (AI) tools designed to operate at human levels have greatly expanded in popularity over the past year. These include OpenAI’s ChatGPT, Google’s Bard and Microsoft’s AI-powered search engine Bing. Such tools, also known as chatbots or generative AI, are computer-powered systems. They are designed to interact smoothly with humans and perform high-level writing and creative work.
In recent months, these tools have demonstrated an ability to produce high-quality work. This has led some technology experts to warn that generative AI systems could end up replacing workers in many industries.
This year, researchers at Harvard Business School and other organizations carried out an experiment. It aimed to test how well AI tools could help workers perform their usual duties or tasks. It involved more than 700 business advisors, called consultants, from Massachusetts-based Boston Consulting Group.
Harvard Business School recently published the results from the experiment in a working paper. The main findings suggest that AI tools like ChatGPT can greatly improve worker performance. For example, researchers found that, on average, workers who used OpenAI’s latest ChatGPT 4 tool completed 12 percent more tasks than non-ChatGPT users. Tasks carried out with help from the AI technology were completed 25 percent faster. And the team found the quality of work performed by consultants using ChatGPT 4 increased by about 40 percent.
However, the paper also noted areas where the performance of consultants using ChatGPT 4 dropped. The researchers said this was especially true with tasks the AI tool was not good at completing. “Of tasks the AI was good at, the experiment showed it significantly improved human performance,” the paper said. “But for tasks ChatGPT 4 was not right for, humans relied too much on the AI and were more likely to make mistakes.”
The team suggests one of the biggest barriers to companies effectively using AI is not knowing which tasks can be completed best with the technology. Finding this out will require businesses to carry out thoughtful research and training efforts in order to find the right mix of AI and human-level work.

7 . Did you know that honeybees aren’t the only insects capable of producing the sweet, sticky, and brown-to-golden-colored natural product we know as honey? There is perhaps the most unusual insect able to change nectar(花粉) into honey called the honeypot ant. Belonging to a kind of ant species, honeypot ants are specialized workers that act as living storage for their fellow ants when food is scarce. Most species of honeypot ants are found in dry regions in Australia, the USA, Mexico and on the African continent, where finding food sources can be tough, so the production and storage of honey is believed to be an adaptation to survive in these rough environments.
Worker ants constantly feed honeypot ants nectar collected from various plants. The only job of honeypot ants is to wolf down nectar. At one point, the honey ants’ abdomens(腹部) become so big that they are unable to move and ready to spill(溢 出) ant honey, so they just hang from the roof of their nest until their fellow ants are in need of food.
Honeypot ants are such a valuable resource that other ant groups will sometimes attack and steal them. In Australia, the locals also prize the honey-filled insects and will dig around for them. In the1990 documentary Trials of Life, David Attenborough himself was filmed putting a honeypot ant into his mouth.
So how does honeypot ant honey compare to honeybee honey? According to one study, researchers find that there are two obvious differences between them. Although the two varieties look very similar at first glance, the honeypot ant honey is sweet, but not quite as sweet as the treat we humans are used to, and has a sour taste that cannot be detected in the honeybee honey.

D.When they want to refuse to feed fellow ants. |

8 . Engineers at Zhejiang University have created China's first brain-like computer, named Darwin Mouse, which can copy the way a human brain works and solve complex calculations while using a small amount of the energy used by traditional supercomputers.
Though the technology is still in its early stages, experts say it could be used to run large, real-time simulations(模拟) and make new discoveries in chemistry, medicine and neuroscience. It could also be used to revolutionise computer design, leading to more powerful and efficient artificial intelligence.
Pan Gang, a professor at the university's College of Computer Science and Technology, said neuromorphic(神经形态的) computing has been a focus of the international scientific and engineering communities for some time and is considered one of the key methods to overcome the major computing challenges for artificial intelligence. Darwin Mouse represented a "major milestone achievement" in China's brain-like computing technology.
In late 2018, the University of Manchester in the United Kingdom upgraded its neuromorphic supercomputer SpiNNaker to use a million processors, enabling it to perform 2 trillion actions a second. This allowed the machine to run extremely large-scale real-time simulations, such as modelling parts of the brain. Darwin Mouse uses significantly fewer processors thanks to the latest developments in brain-like chips made in China, allowing it to perform far better.
Another advantage is low energy costs. When information is transmitted, only neurons that receive and process the signals are activated, while other neurons stay asleep, similar to how a brain works. As a result, the energy consumption can be reduced to a small part of that of conventional supercomputers.
"We hope to keep evolving the Darwin series neuromorphic computer towards reaching human levels of intelligence, thus achieving more powerful artificial intelligence with significantly less energy use. It is hopeful that brain-like computers will make their way into our daily lives as the hardware and the software for the technology mature," Pan said.
1. Which can be inferred about Darwin Mouse?A.Brain-like and easy to operate. | B.Powerful and energy-saving. |
C.Traditional but efficient. | D.Advanced but impractical. |
A.To show it can run more complex simulations. |
B.To prove no computers can compare with human brains. |
C.To stress the importance of brain-like chips. |
D.To highlight the advantage of Darwin Mouse. |
A.Positive. | B.Sceptical. | C.Tolerant. | D.Objective. |
A.Outstanding Engineers of China |
B.The Brain-Like Computer Makes Its First Appearance in China |
C.Darwin Mouse, a Famous Mouse |
D.Artificial Intelligence Has a Bright Future |

Food is important to us human beings. However, some students are seen wasted food in the canteen these day. And now the situation is getting seriously. Saving food was our duty because food doesn’t come easily. We must respect or save food to show our gratefulness. Meanwhile, if we save food, more people in the poor areas can get food eat, which also helps fight against hunger. I also suggest those which waste food should get punish. Only then will they save food and respect their meals from the bottom of our hearts. As far as I’m concerned, we students should form a good habit of saving food. Let’s take the action now!
