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.

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.

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!
4 . Feeling hungry? Then what’s the easiest way to satisfy your hunger? Many of us will reach for a takeaway menu and order some delicious- but possibly unhealthy -food. And our increasingly busy and stressful lives add to our need to buy ready-made food on the go or delivered to home.
Eating options are endless, and new technology means we can feed our desires at the push of a button. Takeaway delivery apps make ordering food quick and convenient, and during the recent coronavirus（冠状病毒）crisis, it provided a lifeline to those stuck at home with nothing to cook or who lacked the skills to prepare a meal for themselves. It’s estimated that in the UK alone, people eat three million takeaway meals a day, and the three biggest delivery apps together offer a choice of 100 dishes from 60, 000 restaurants.
It’s no wonder we are tempted to skip the grocery shopping, bypass the kitchen, and enjoy something that someone else has prepared. But ordering a pizza, a spicy curry or a box of noodles, can come at a price both financially and to our health. Eating too much processed and unhealthy fast food has some effect on obesity and the risk of developing certain diseases. A few years ago, The BBC Good Food Nation Survey found that most people ate fast food on average two days per week. But, in the 16 to 20-year-old category, one in six ate fast food at least twice a day.
Of course, reducing salt, sugar and fat is one way to make takeaway food healthier, as well as offering smaller portion sizes. But the best advice is to find a cooking book and try making your own healthy meal. And if you haven’t got time, try ordering a healthier alternative from the menu.
