1 . Television has transformed politics in the United States by changing the way in which information is spread, by altering political campaigns, and by changing citizen’s patterns of response to politics. By giving citizens independent access to the candidates, television reduced the role of the political party in the selection of the major party candidates. By centering politics on the person of the candidate, television accelerated the citizen’s focus on character rather than issues.

Television has altered the forms of political communication as well. The messages on which most of us rely are briefer than they once were. The stump speech, a political speech given by traveling politicians and lasting 1 to 2 hours, which was popular in the nineteenth-century, has given way to the 30-second advertisement and the 10 second “sound bite” in broadcast news. Increasingly the audience for speeches is not that standing in front of the politician but rather the viewing audience who will hear and see a short video of the speech on the news.

In these simplified forms, much of what comprised the traditional political speech of earlier ages has been lost. In 15 or 30 seconds, a speaker cannot establish the historical context that shaped the issue in question, cannot detail the probable causes of the problem, and cannot examine alternative proposals to argue that one is preferable to others. In short videos, politicians assert (断言) but do not argue.

Because television is an intimate (亲密的) medium, speaking through it requires a changed political style that is more conversational, personal, and visual than that of the old-style stump speech. Reliance on television means that increasingly our political world contains memorable pictures rather than memorable words. Schools teach us to analyze words and print. However, in a world in which politics is increasingly visual, informed citizenship requires a new set of skills.

Recognizing the power of television’s pictures, politicians craft televisual, staged events designed to attract media coverage. Much of the political activity we see on television news has been crafted by politicians, their speechwriters, and their public relations advisers for televised consumption. Sound bites in news and answers to questions in debates increasingly sound like advertisements.

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.

In recent years, China has been working hard to improve living conditions in rural areas through a program called the New Rural Development Initiative.    1     goal of this initiative is to improve infrastructure (基础设施), modernize farming practices, and enhance the overall quality of life for those     2     (live) in the countryside.

One important aspect of the initiative is the improvement of rural infrastructure    3       includes the construction of better roads, bridges, and watering systems     4     (improve) the efficiency of transportation and agricultural activities.

Another key focus is the promotion of modern agricultural    5     (technique). By introducing advanced farming methods and technologies, such as organic farming and the use of

machinery, farmers are able to increase their productivity and income     6       damaging the environment.

Furthermore, the initiative emphasizes the importance of preserving traditional culture and heritage in rural communities. Efforts    7     (make) to regenerate local traditions, which not only enriches the cultural     8     (diverse) of the countryside but also creates new opportunities for cultural tourism and sustainable development. The initiative also aims to enhance the living environment in rural areas through the restoration of traditional houses     9     the construction of public facilities.

Through the initiative, China is working hard to create a more prosperous (繁荣的) and     10     (harmony) countryside, providing its rural residents with better opportunities and an improved quality of life.

5 . Nowadays, people are increasingly interacting with others in social media environments where algorithms control the flow of social information they see. People’s interactions with online algorithms may affect how they learn from others, with negative consequences including social misperceptions, conflict and the spread of misinformation.

On social media platforms, algorithms are mainly designed to amplify (放大) information that sustains engagement, meaning they keep people clicking on content and coming back to the platforms. There is evidence suggesting that a side effect of this design is that algorithms amplify information people are strongly biased (偏向的) to learn from. We call this information “PRIME”, for prestigious, in-group, moral and emotional information.

In our evolutionary past, biases to learn from PRIME information were very advantageous: Learning from prestigious individuals is efficient because these people are successful and their behavior can be copied. Paying attention to people who violate moral norms is important because punishing them helps the community maintain cooperation. But what happens when PRIME information becomes amplified by algorithms and some people exploit (利用) algorithm amplification to promote themselves? Prestige becomes a poor signal of success because people can fake prestige on social media. News become filled with negative and moral information so that there is conflict rather than cooperation.

The interaction of human psychology and algorithm amplification leads to disfunction because social learning supports cooperation and problem-solving, but social media algorithms are designed to increase engagement. We call it functional mismatch. One of the key outcomes of functional mismatch is that people start to form incorrect perceptions of their social world, which often occurs in the field of politics. Recent research suggests that when algorithms selectively amplify more extreme political views, people begin to think that their political in-group and out-group are more sharply divided than they really are. Such “false polarization” might be an important source of greater political conflict.

So what’s next? A key question is what can be done to make algorithms facilitate accurate human social learning rather than exploit social learning biases. Some research team is working on new algorithm designs that increase engagement while also punishing PRIME information. This may maintain user activity that social media platforms seek, but also make people’s social perceptions more accurate.

6 . In a world that often feels fast-paced and restrained to routines, the desire for van (房车) life and mobile living has captured the hearts of many seeking an alternative lifestyle.     1     From the freedom to explore new horizons to fostering a minimalist mindset, here are some captivating advantages of embracing van life.

Liberation from Materialism

The confined space of a van encourages a minimalist lifestyle, where experiences are valued over possessions.     2     With minimal monthly expenses, such as parking fees and fuel costs, van dwellers can allocate resources to experiences rather than high rent or house payments. This mobile living is supported by the degrowth movement, which believes that economies should focus on securing the minimal basic needs instead of consumption and consumerism.

Exploration and Flexibility

The ability to follow adventure wherever it takes you is one of the most amazing aspects of living in a van. You can choose to wake up at dawn over the ocean one day and find yourself in a forested mountainside the next. Living in a van frequently involves being close to the outdoors surrounded by the beauty of nature.     3    

Minimal Ecological Footprint

    4     They adopt solar panels and efficient water systems , further minimizing their impact on the environment. People who choose to live in mobile homes believe that eventually, global warming and extreme weather might bring an end to sedentary (定居的) living patterns.

Through the open road, the beauty of nature, and the friendship of fellow adventurers, van life presents a unique avenue for enriching the human experience.     5    

8 . Since the AI chatbot ChatGPT was released in 2020, we’ve been hearing about the threat posed by artificial intelligence. A statement signed by academic experts and tech industry figures even branded AI an “extinction risk.”

In education, there have been concerns that ChatGPT could negatively affect the learning process of students. For example, students could ask ChatGPT to write their coursework for them, skipping the research and writing effort that leads to a better understanding of the topic in question. Perhaps a better approach would be to change and enhance how we teach and assess the outcomes of learning.

Making education more focused on practical skills and the use of knowledge in problem solving could ensure a deeper understanding on the part of students. AI could be used for guidance, in much the same way we currently use calculators, to help enrich people’s knowledge.

However, risks do exist. In May 2023, for example, a US lawyer admitted using ChatGPT for case research. The lawyer’s filing was found to reference legal cases that didn’t exist. The chatbot had made them up. It’s not the first time that these “AI hallucinations” have been reported.

Then we have the very real risk that AI could be used for illegal purposes such as identity theft. For example, criminals could use AI to clone someone’s voice. They could then phone family members and try to convince them to give out sensitive information that could be helpful for accessing bank accounts. A variant of AI-driven identity theft is the use of deepfake videos.

However, Bill Gates, the Microsoft co-founder, sounds less worried than some other executives in Silicon Valley about the risks of artificial intelligence. In a blog post on Tuesday, he wrote, “This is not the first time a major innovation has introduced new threats that had to be controlled. We’ve done it before.”
