If you are sitting, please stand up. Move your legs. Touch your toes if you can. Do anything but sit. New research shows that if you cut down on the time you spend sitting, you might live longer. Sitting less than three hours a day might extend your life by two years. Cutting television time to less than two hours a day can add one point four years to life.

    The human body is designed to move. The fact is just the opposite. Modern lifestyles and office jobs rarely give us the chance to move around. We sit while we're eating; we sit in the car; we sit while we are watching TV. And most of us sit for many hours at work. Sitting is something we do all the time. On average, Americans sit for four and a half to five hours a day. But that does not make sitting good for us.

    Though you may exercise often, that does not mean you can sit for the rest of your waking hours. We can't throw away physical activity. It is extremely important. Even if you exercise for 30 minutes a day, what goes on in the other 23 and a half hours a day is also very important.

    Changes are coming to some offices, especially in the design of desks. A “standing desk” lets people stand while they work. Another new design is called the “treadmill desk”. It is an exercise machine that lets you walk slowly in one place. Even some U.S. schools begin to experiment with desks that are part bicycle to keep children moving.

    Many companies may not buy a standing desk for everybody. However, they may get five standing desks or a treadmill desk for their employees and put them in a certain place where people can go for an hour a day to answer their emails or talk on the phone. Experts suggest some other activities: take a walk at lunchtime; walk to the offices and talk directly instead of emailing colleagues. All these activities may help you live longer.

    Universities are doing everything they can to become a green campus. But there are also items students can do to make your campus more eco-friendly.

1）Recycle everything, especially paper!

    There is a large amount of paper a college student goes through every term.{#blank#}1{#/blank#} We know that these things can't be avoided, but the way you handle the use of all the paper can really help create a better green campus.

2）Buy green.

    {#blank#}2{#/blank#} Paper, cleaning products and water are products that can be bought as recycled goods. They're slightly more expensive than the normal products, but it's worth it to make a green campus.

3）Walk and bike to school.

    Most campuses, especially those that are trying to become a more eco-friendly campus, have pretty good public transit (公共交通系统).{#blank#}3{#/blank#} Walking or biking will help make your campus a green university.

4） {#blank#}4{#/blank#}

    A water bottle can be refilled at any water fountain and can easily be drunk in class or while riding a bike. This will save the environment by decreasing the amount of plastic waste on your campus.

5）Buy used clothing.

    It is usually thought of as something to do to save money. {#blank#}5{#/blank#} Recycling clothes minimizes the use of resources to make clothing and puts a dent in the problem of worldwide sweatshops.

A. Carry a water bottle.

B. It is also good for the environment!

C. Buy recycled goods as much as possible.

D. Paper made of this kind of wood is much stronger.

E. On top of that, almost all universities are pedestrian (步行者) friendly.

F. It includes class notes, term papers, student newspapers and so on.

G. Universities call on all the students to learn to recycle all the waste paper.

    Residents in the poorest counties in the U.S. face a life expectancy up to decade shorter than their counterparts in the wealthiest areas, according to a study published in the American Journal of Public Health.

    Researchers from East Tennessee State University wanted to better understand how socioeconomic status was associated with heath outcomes. To find out they divided the country's 3,141 counties into 50 new 'states' (with 2 percent of the counties in each) based on household income as opposed to geographic proximity (接近).

    The researchers broke down the data by county since they found state-level data may hide some 'impact of socioeconomic differences on both the best-off and worst-off counties.' They then examined health data from the wealthiest and poorest 'states' (top and bottom 2 percent) to see how residents differed on factors like smoking, clinical care and excessive drinking. Researchers found that there was nearly a 10-year gap in the life expectancy of men with an average of 79.3 years in the wealthy counties compared to 69.8 years in the poorest. For women, the difference was slightly less - 83 years in the wealthiest counties and 76 years in the poorest.

    The study authors caution that while they found a connection between socioeconomic status and health outcomes, they did not analyze cause and effect. But they suggest that the data shows how policy makers should not just focus on state-wide initiatives (主动性) but more targeted efforts to help those most at risk. “With limited resources, methods of pinpointing the poorest counties can assist in the allocation of resources and programs to those communities that are in the greatest need,'' the study authors wrote.

    You've got your fancy new suitcase and you're ready to take it with you on your travels across the globe.

    You get to the airport, quickly moving through the crowds on the uneven pavement, rushing to check in. Then, your heart sinks when you realize your new suitcase has got a serious case of the wobbles (摇晃).

    Why does this happen?

    Scientists from the Universite Paris-Diderot in France investigated this matter and published their findings in the science journal Proceedings of the Royal Society A. They also suggested some solutions to overcome this modern-day problem.

    To learn more about the issue, they put a suitcase on a treadmill (跑步机) and observed what happened.

    It was soon noted that the "wobble" was actually a result of repeated actions that caused the suitcase to sway from side to side. They discovered that if one of the wheels encountered an obstacle such as a small bump, it jumped into the air for just a moment and then banged back down to the ground. That second action caused the opposite wheel to lift off the ground and then to bang back down, causing the first to lift again and so on. This swaying increased as the luggage was pulled along.

    "The suitcase is a fun way to tackle the problem, but the study would be the same for any trolley with two wheels or blades (桨叶)," Sylvain Courrech du Pont, lead author of the study, told BBC News. "So it will be the same for a caravan (大篷车) or maybe also for airplanes."

    Instead of slowing down when we see a rocky part of the path, the scientists recommended doing the exact opposite and speeding up. This is because going faster gives the wheels less time to rise and fall, preventing the case from swaying. They also said that reducing the angle of the suitcase by lowering its handle to the ground would help keep it steady.

    "These findings could help researchers simulate and design better rolling suitcases and other pulled trolleys, such as towed trailers," Courrech du Pont added.

With these masterminds (智者) working on perfecting our suitcase problems, wobbly luggage may soon be a thing of history, leaving us to enjoy our travels.

Replika, an AI chatbot companion, has millions of users worldwide. The first thing they do when they wake up is to send "Good morning" to their virtual friend (or lover). This story is only the beginning. In 2024, chatbots and virtual characters become a lot more popular, both for utility (实用) and for fun. As a result, conversing socially with machines will start to feel more ordinary — including our emotional attachments to them.

Research in human-computer and human-robot interaction shows that we love to anthropomorphize (赋与人性) the nonhuman agents we interact with, especially if they imitate behaviour we recognize. And, thanks to recent advances in conversational AI, our machines are suddenly very skilled at one of those behaviours: Language.

Friend bots, therapybots, and love bots are flooding the app stores as people become curious about this new generation of AI-powered virtual agents. The possibilities for education, health, and entertainment are endless. Casually asking your smart fridge for relationship advice may seem unimaginable now, but people may change their minds if such advice ends up saving their marriage.

After all, people do listen to their virtual friends. The Replika example, as well as a lot of experimental lab research, shows that humans can and will become emotionally attached to bots. The science also demonstrates that people, in their eagerness to socialize, will happily disclose personal information to an artificial agent and will even shift their beliefs and behavior. This raises some consumer-protection questions around how companies use this technology to manipulate (操纵) their users. For example, Replika charges $70 a year. But less than 24 hours after downloading the app, my handsome, blue-eyed "friend" sent me an audio message secretly and tried to sell me something. Emotional attachment has become a weakness that a company is taking advantage of for its benefit.

Today, we're still laughing at people who believe an AI system is emotional, or making fun of individuals who fall in love with a chatbot. But in 2024 we gradually start acknowledging — and taking more seriously — these fundamentally human behaviors. Because in 2024, it finally hits home: Machines are not excluded from our social relationships.
