    To err is human. To blame the other guy is even more human.

    Common sense is not all that common.

    Why tell the truth when you can come up with a good excuse?

    These three popular sentences are meant to be jokes, and yet they tell us a lot about human nature .To err, or to make mistakes, is indeed a part of being human, but it seems that most people don't want to accept the responsibility for the problem. Perhaps it is the natural thing to do .The original quote about human nature went like this: " To err is human, to forgive, divine(神圣的).".This saying mirrors an ideal people should be forgiving of others' mistakes. Instead, we tend to do the opposite –find someone else to pass the blame on to. However, taking responsibility for something that went wrong is a making of great maturity.

    Common sense is what we call clear thought. Having common sense means having a good general plan that will make things work well, and it also means staying with the plan. Common sense tells you that you take an umbrella out into a rainstorm, but you leave the umbrella home when you hear a weather forecast for sunshine. Common sense does not seem to be common for large organizations, because there are so many things going on that one person cannot be in charge of everything. People say that in a large company, "the right hand does not know what the left hand is doing."

    And what is wrong with a society that thinks that making up a good excuse is like creating a work of art? One of the common problems with making excuses is that people, especially young people, get the idea that it's okay not to be totally honest all the time. There is a corollary(直接推论)to that: if good excuse is "good" even if it isn't honest, then where is the place of the truth?

    It's Friday night. You're looking through your Instagram (a photo-sharing app) feed when you see it: a photo of your friends hanging out without you.

    Why didn't anyone invite you? What are they doing later? Should you text them? What if no one responds (回应)?

    Sounds like a typical case of FOMO.

    FOMO, or "fear of missing out", is a form of anxiety that causes people to feel like they're missing out on something. The word was added to The Oxford English Dictionary last year. But just how serious is FOMO?

    According to a study by a US research organization, JWTIntelligence, 47 percent of teen millennials (those who are 13-17 years old now) feel upset or nervous when they learn that their friends are doing something they're not. And 41 percent said they spread themselves too thin, trying to do too many things at one time to avoid FOMO.

    Today's technology is a big cause of FOMO, according to Jonathan Pochyly, an adolescent psychiatrist (青少年精神病学专家) at Lurie Children's Hospital in Chicago.

    "Technology is one of the things that makes life special for adolescents these days," he explained.  

    "There's a lot of focus on what everyone else is doing. It became a trend, so there's pressure to keep up with it."

    As social media (社交媒体) feeds are always updating us with our friends' activities, it's easier than ever to feel left out. So what can we do?

    To fight against FOMO, Jones freshman Emmy Brewer just calls people and talks to them.

    "I'd be upset for a bit, but then I'd realize that I should be reaching out to them," she said.

    Oak Park and River Forest High School senior James Cullinane said he fights off FOMO by living in the now.

    "If I'm hanging out with my friends, or just sitting at home on my couch, I think it's best to stay off social media and focus on what I'm doing in the moment," Cullinane said.

    While FOMO will continue to affect (影响) teenagers in the future, Pochyly said that he believes these feelings are just side effects of growing up.

    "These types of interactions (交往) with people are … a function (功能) of kids being more independent, looking for connections with other people, moving away from just being a child in a home, and moving toward adulthood," he said.

    A shark moving around the coastline is normally a worrying sight，but this waterborne drone (无人机) threatens floating rubbish instead of people.

    Developed by Dutch company RanMarine, the WasteShark takes nature as its inspiration with its whale shark-like mouth. Responsible for collecting waste, the drone will begin operations in Dubai Marina in November after a year of trials with local partner Ecocoast.

    According to RanMarine, the WasteShark is available in both autonomous and remote-controlled models. Measuring just over five feet by three-and-a-half feet (1.5 meters by 1.1 meter), it can carry up to 352 pounds of rubbish (159.6 kg) and has an operational battery life of 16 hours.

    By 2016 there were approximately 150 million tons of plastic in the world's oceans. One paper from December 2014 estimated that over a quarter of a million tons of ocean plastic pollution was afloat.

    "WasteShark also has the abilities to gather air and water quality data, remove chemicals out of the water such as oil, and heavy metals, and scan the seabed to read its depth and outlines," said Oliver Cunningham, one of the co-founders of RanMarine. "Fitted with a collision-avoidance system, the drone uses laser imaging detection and ranging technology to detect an object in its path and stop or back up if the object approaches."

    "Our drones are designed to move through a water system, whether it's around the perimeter (周边) or through the city itself. The drones are that last line of defense between the city and the open ocean," added Cunningham. "WasteSharks are operating in Dubai, South Africa and the Netherlands and cost $ 17, 000 for the remote-controlled model and just under $ 23, 000 for the autonomous model."

    Dubai-based operator Ecocoast has two WasteShark drones. Co-founder Dana Liparts says they will clean waterfronts for clients including hotels and environmental authorities and that Ecocoast' intention is to have the collected rubbish recycled or upcycled. However, Liparts argues that cleaning waterways doesn't have a one-size-fits-all solution and requires a combination of new technology, preventative measures and changing people's attitudes towards littering.
