Even if you are not into artificial intelligence, it is time to pay attention to ChatGPT. ChatGPT is an AI chatbot system that Open AI released to show off and test what a very large, powerful AI system can complete.

ChatGPT is built on top of the Open AI GPT-3 family of large language models. It lets you type natural-language clues and then offers conversational responses. It remembers the thread of your dialogue, using previous questions and answers to form its next responses. It finds relevant information in its oceans of training data, and transforms that into texts.

You can ask it countless questions and often will get useful answers. For instance, you can ask it encyclopedic (百科知识的) questions like “Explain Newton’s laws of motion.” You can tell it “Write me a poem.” and when it does, say “Now make it more exciting.” You can ask it to write a computer program that will show you all the different ways you can arrange the letters of a word.

A few days after its launch, more than 1 million people were trying out ChatGPT. UBS analyst Lloyd Walmsley estimated in February 2023 that ChatGPT reached 100 million monthly users in January, completing in 2 months what took TikTok about 9 months and Instagram two and a half years.

Many people fear that ChatGPT might help students cheat better. But as many other technology developments, it is not a simple black-and-white situation. Decades ago, students could copy encyclopedia entries and use computers and more recently, they have been able to use search engines and Wikipedia. ChatGPT offers new abilities for everything from helping with research to doing your homework for you.

Dustin York, an associate professor at Maryville University, hopes educators will learn to use ChatGPT as a tool and realize it can help students think critically. “Educators thought that Google, Wikipedia, and the Internet itself would ruin education, but they did not.” York said. “What worries me most are educators who may actively try to discourage the recognition of AI like ChatGPT. It is a tool, not a villain (反派).”

A parent might place his daughter’s drawing on the fridge out of a love for his child rather than for the wonderful image, but for many people, that children art is actually quite amazing. In fact, adult artists were often inspired by children’s drawing. For the museum-goers out there who tend to point to a piece of modern art and say, “My kid could have made that !”It’s worth remembering that often, that’s actually just what the artist had in mind.

For many kids, drawing is exciting not because of the final product it leads to, but because they can live completely in the world of their drawing for a few minutes. Even children are scribbling(涂鸦), they’re representing through action, not through pictures. Liane Alves, a prekindergarten teacher, recalled a student who presented her with a drawing featuring a single straight line across the page. Alves assumed the child hadn’t given too much thought to the drawing until he explained that the line was one of the stems (茎) from The Princess and the Pea, one of the fairy tales they read in class.

Maureen Ingram, who’s a preschool teacher at the same school,said her students often tell different stories about a given piece of art depending on the day, perhaps because they weren’t sure what they intended to draw when they started the picture. “We as adults will often say, ’I’m going to draw a horse, ’and we set out. . . and get frustrated when we can’t do it, ”Ingram said. “Children seem to take a different approach, where they just draw, and then they realize, ’it is a horse. ’”

And what about those odd or scary-looking drawings? Does that mean kids are telling themselves stories that are odd or scary? It’s hard to say, but it’s rarely a good idea to over-interpret it. Ellen Winner, a psychology professor, pointed to parents who worry when their kid draws a child bigger than the adults. What’s most important to remember is that“children’s art has its own logic,” Winner said. “Children are not being crazy. ”

Gear guide—buying a backpack

A quick glance through my outdoor trade directory reveals 49 companies that sell or make backpacks. If they all produce ten backpacks then we have a frightening number for the humble beginner to choose from. 【小题1】

The first and most vital consideration is your anticipated load. If you have short summer evening walks then a small backpack would be fine, but if your walks are day-long and year-round then your pack will need to be bigger. Mine typically contains packed lunch, waterproofs, clothing I’ve taken off during the day, a first aid kit and an emergency shelter. Sometimes in winter I add a sleeping bag and a torch. 【小题2】 My current backpack is a Crag-hopper AD30(30 litres)which is just big enough. Admittedly I do often lead walking parties in remote places so perhaps my added responsibilities cause me to carry more. Compare my list with yours to see if you need as much carrying space.

【小题3】 Choose a light pack, but make sure it can take the weight of what you are carrying and it can support the load comfortably on your back. Today you can get quite technically advanced backpacks: advanced fabrics, a variety of side pockets, internal frames, adjustable belts, and clever systems to keep your back cool.

You also need to look inside. It may seem obvious, but you should choose a backpack that allows you easy access. 【小题4】 It’s also important to choose a backpack that fits the length of your back. Being six feet I need a long, thin one rather than a short, wider one. If I use the latter, I’ ll have a hip belt round my stomach!

【小题5】 Obviously you can’t see it when it’s on your back, but why buy something that won’t look good on you? After all, there’s no shortage of colors or designs to choose from.
