【推荐2】The American dream is the faith held by many people in the United States of America that through hard work, courage, creativity and determination, they can achieve a better life for themselves. More specifically, they agree on how to get ahead in America: get a college education, find a reliable job, and buy their own house. But do Americans still believe in that path, and if they do, is it attainable?

The most recent National Journal poll (民意测验，投票) asked participants about the American dream, what it takes to achieve their goal, and whether or not they felt the control over their ability to be successful. Obviously, the results show that today, the idea of the American dream and what it takes to achieve it looks quite different from it did in the late 20th century. On the whole, people felt that their actions and hard work — not outside forces — were the deciding factors in how their lives turned out. But the participants had definitely mixed feelings about what actions make for a better life in the current economy.

In the last seven years, Americans have grown more pessimistic about the power of education to lead to success. Even though they see going to college as a fairly achievable goal, a majority 52 percent think that young people do not need a 4-year college education in order to be successful.

Miguel Maeda, 42, who has a master’s degree and works in public health, was the first in his family to go to college, which has allowed him to achieve a sense of financial stability his parents and grandparents never did. While some, like Maeda, emphasized the value of a degree rather than the education itself, others still see college as a way to gain new viewpoints and life experiences. Sixty-year-old Will Fendley, who had a successful career in the military and never earned a college degree, think “personal drive” is far more important than just go to college. To Fendley, a sense of drive and purpose, as well as an effective high-school education, and basic life skills, like balancing a checkbook (支票簿), are the necessary elements for a successful life in America.

【推荐1】I’m 62 now and always planned to volunteer with older people when I retired. I knew there was such a big gap in the care and support this generation receives and I found the thought heartbreaking-no one should have to feel lonely and stuck at home.

Since I started volunteering three years ago, my team of volunteers have set up seven groups in our town. We host tea parties for those aged 75 and older who live on their own and regularly provide support, friendship and companionship for the most isolated older people in the community.

Working with my older neighbors is rewarding. To hear their stories and the hardships they have overcome is inspiring. I feel like I’m making a positive difference to the lives of older people by sharing my time with them, helping them stay active and social and making it clear to them that they are valued by our community.

As an area coordinator (协调人), I also help recruit(招募) and manage volunteers, without whom none of the work would be possible. So many go above and beyond what’s asked, giving their time, energy and kindness, just because they care. I’ve found so much enthusiasm from people wanting to make the lives of our older neighbors better, and they are a constant source of inspiration for me.

I’ve met so many amazing people from all walks of life (各行各业). It’s one of the best things I’ve ever done and it has enriched my life so much. I will keep focusing on reducing loneliness and isolation among the elderly and helping older people enjoy the old age that they deserve.

【推荐2】Healthy Habits，Healthy Body

Feel tired lately？ Has a doctor said he can’t find anything wrong with you？ Perhaps he sent you to a hospital，but all the   advanced equipment there shows that there is nothing wrong with you.

Then，consider this： you might be in a state of subhealth(亚健康).

Subhealth，also called the third state or gray state，is explained as a borderline state between health and disease.

According to   the   investigation   by   the   National   Health Organization，over 45 percent of subhealthy people are middle­aged or elderly.The percentage is even higher among people who work in management positions as well as students around exam weeks.

Symptoms(症状) include a lack of energy，depression (压抑)，slow reactions，insomnia (失眠)，agitation，and poor memory.Other symptoms include shortness of breath，sweating and aching in the waist and legs.

The key to preventing and recovering from subhealth，according to some medical experts， is to form good living habits，alternate work and rest，exercise regularly，and take part in open­air activities.

As for meals，people are advised to eat less salt and sugar.They should also eat more fresh vegetables， fruit and fish because they are rich in nutritional elements－vitamins and trace elements that are important to the body.

Nutrition(营养) experts point out that it is not good to eat too much at one meal because it may cause unhealthy changes in the digestive tract(消化系统).They also say that a balanced diet is very helpful in avoiding subhealth.

【推荐3】OpenAI’s automated AI-powered chatbot ChatGPT has taken the Internet by storm, but not without creating a few issues on the way. With writers, marketers, and seemingly everyone else in between using ChatGPT to generate content, companies worldwide are staring down a tsunami of AI-generated content. With issues of safety and stolen contents constantly swirling around ChatGPT and its output, OpenAI has now released GPT-Classifier, a tool designed to detect whether the text you’re reading was generated by ChatGPT or one of its other GPT tools.

GPT-Classifier attempts to figure out if a given piece of text was human-written or the work of an AI-generator. While ChatGPT and other GPT models are trained extensively on all manners of text input, the GPT-Classifier tool is fine-tuned on a dataset of pairs of human-written text and AI-written text on the same topic. In other words, the GPT-Classifier attempts to compare similarities between known human text and known AI text to find inconsistency that reveal the source writer.

While the idea of easily spotting AI-generated text will be music to the ears of editors and educators, OpenAI has warned that its classifier is not fully reliable.

A test of the GPT-Classifier spotted a human-generated example and marked it very unlikely to be AI-generated, and also correctly indicated that a ChatGPT-generated piece on USB issues was possibly AI generated. Currently, GPT-Classifier correctly identifies 26% of AI-written text while labelling 9% of human text as AI-written. OpenAI also notes that the tool’s accuracy typically improves as the length of the input text increases. For now, although GPT-Classifier is up and running and available for testing, it’s best to take its labelling with a pinch of salt.

Even with the GPT-Classifier’s limitations, the demand for reliable ChatGPT detection is likely to see many people turn to this tool. OpenAI’s commitment to building and releasing a free GPT detection tool is important because as more students, writers, programmers, and others use AI-text generation tools, understanding and detecting this input will become vital.
