2 . Creative people are more likely to make the most of their idle (空闲的) time during a typical day by exploring their mind, a new study by University of Arizona researchers suggests.

In the study, the researchers divided the study into two parts. For the first experiment, the researchers asked each participant to sit alone in a room for 10 minutes without any access to digital devices. In the absence of any particular prompt (提示), the participants were asked to speak out their thoughts aloud in real time. The recorded files from 81 participants were then analyzed.

The researchers assessed the participants’ creativity through a thinking test, a lab-based verbal test that measures a person’s ability to think outside of the box. Participants who performed well in the thinking test had thoughts that flowed freely and were associated with one another, often indicated by phrases such as “this reminds me of” or “speaking of which”.

“While many participants had a tendency to jump between seemingly unrelated thoughts, creative individuals showed signs of thinking more associatively,” Raffaeli said, who was a senior author of the paper.

The first experiment also found that creative people were more engaged in their thoughts when they were left alone without distractions (干扰), such as the cellphone and Internet. “Creative people rated themselves as being less bored, even over those 10 minutes. They also spoke more words overall, which indicated that their thoughts were more likely to move freely,” Raffaeli said.

To further prove their initial findings, the researchers extended their study in the context of a much larger span of time—from 2020 to 2023 when many people were alone with their thoughts more often. For the second experiment, over 2,600 adults answered questions through a smartphone app called Mind Window. Participants who self-identified as being creative reported being less bored and more engaged in their thoughts during that period.

The researchers are continuing this line of work using their Mind Window app. They encourage people to download and use the app to help scientists understand how people across the world think in their everyday lives. “Understanding why different people think the way they do may lead to promising interventions to improve health and well-being,” Raffaeli said.

3 . Reducing food waste is easy — just ask the students at a school in Wood bridge, America, who have become experts at sorting their lunchtime trash (垃圾). Since the fall of 2019, they have actively participated in a successful food-waste diversion program that not only saves money but also contributes to reducing the amount of trash that heads to landfills.

Actually, this program plays a crucial role in facing up to the challenges of climate change. By reducing food waste,the school minimizes the amount of trash sent to landfills, thereby reducing harmful methane emissions (沼气排放). The school’s program is making a significant impact. Each month, it moves over 1,300 pounds of food waste, resulting in an estimated reduction of 772 pounds in CO, emissions and the production of 180 kilowatt-hours of energy, according to Blue Earth Compost in America.

At school, when students are done eating lunch, they head to an appointed section — a row of desks, garbage cans and containers — where they sort their trash. Leftover liquids, such as juice or milk,are emptied into a big basin on the floor. The juice containers and plastic water bottles are placed into another container to recycle. Additionally, prepackaged, unopened snacks such as bags of carrots as well as produce such as apples and bananas are “rescued” and placed into a big basket with a handwritten “Donations” sign taped to it to send to the town’s senior center.

The benefits extend beyond environmental awareness. The program reduces trash-carrying costs as less weight goes into the trash bins,making it easier for cleaners to manage. The students also find this planet-friendly practice enjoyable and meaningful, considering it a small game that contributes to a bigger cause. This initiative proves that collective efforts, even on a smaller scale, can lead to significant changes, not only in waste reduction but also in educating a generation committed to preserving our planet.

5 . 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.

6 . “The new normal” is one of those phrases that can accurately apply to a wide variety of life situations, including a medical diagnosis, death or change in life and work. The phrase implies both the newness of each of those circumstances, as well as the necessity that they will need to be normalized, integrated into the reality of our daily lives. Once we’ve settled into new routines and emotional patterns, our “normal” won’t be quite so new anymore, will it? The question is a subject of debate.

There is a large middle ground between the event that increases the need for “the new normal” and its final acceptance. Some people think it can’t handle tragedies. But the phrase keeps coming up in conversation, and it has made me realize that“normal”is the last word I would use to describe the fragile place I currently occupy. I find myself there as I mourn the loss of my grandfather, who died in September. For example, the new normal is to have Thanksgiving without Grandfather, then to remember him on what would have been his 75th birthday just a few days later. In other words, during this year of firsts, the new normal is a time of transition, not of arrival.

It strikes me that this is something to be celebrated, not worried over. Part of living positively is meeting ourselves wherever we are. And as I continue to navigate this in-between time, this period of slowly accepting my father’s absence from the Earth, I recognize that each step along the way is a worthwhile part of a healthy grieving process.

The same idea would apply to more positive changes, like a new home or job, as well as the challenges of the end of a relationship or a difficult medical reality. The new normal isn’t something any of us step into all at once. It’s something we become, move toward, and, eventually, accept. Let’s not be in a rush to reach that destination. The journey has much to teach us.

7 . The sharing economy is an economic model known as a peer-to-peer(P2P)based activity of getting, providing, or sharing goods and services that is often promoted by on-line platforms (平台) It allows persons and groups to make money from the assets (资产) which is not _______ .In a sharing economy, underused assets such as parked cars and spare bedrooms can be _______ when they are not used. In this way, physical assets are shared as _______ .

This could mean putting them in a better position that makes it possible for them to ask _______   prices to get a bigger market share.

Another _______ is that lack of watching over businesses will lead to _______ uses of both buyers and sellers in the sharing economy. There have been many cases ________ known to the public like hidden cameras in rented rooms, lawsuits (诉讼)over ________ treatment of ridesharing drivers by the platforms ________ employ them, and even murders of customers by real or ________ ridesharing providers.

This can happen when users are allowed to ________ who they will share their homes or cars with, or because of the database of users with poor credit history or bad behaviour ________ .

10 . Conflict (冲突) between teenagers and parents happens for a lot of reasons. Sometimes conflict happens between teenagers and parents just because conflict happens between human beings anyway. Humans have different needs, different feelings, different opinions about what they want, and the relationship with people can be really difficult. However, teenagers can cause further conflict because of the hormonal (生理的) changes that are happening and the stage of life that they're in.

Teenagers and parents have different understanding about rules and at times they find it difficult to look into the future. So parents and teenagers will often experience conflict about many things, do chores, homework, whether teenagers speak respectfully or not and about what they're allowed to do.

Before we think about rule boundaries (界线) for teenagers, we need to make sure that we have a really good relationship base. There's no point saying “From now on, you have to listen to me”: if you don't have a positive relationship with your teenager. We need to go back and make sure there is some degree of shared respect, and some degree of positive communication and enjoyment being together. you do that first, it means that rule boundaries are a lot easier to set up.

Often we're dealing with conflict on the fly. This is not the right time to be dealing with it. We really want parents and teenagers to sit down and think about the kinds of things that may happen in the house before the problems come. The more detailed your rule boundaries are for teenagers, the more likely it is that they are going to follow them. So this means we don't have rule boundaries like “Have the bathroom cleaned”. It needs to be “The floors mopped, nothing on the countertop and the mirrors cleaned by ten o'clock every Saturday”: Rule boundaries need to be written down, and set out ahead of time so the teenager knows exactly what's expected.
