    If you thought helicopter parents were too much, wait till you learn about “lawnmower (割草机) parents”. These are the next generation of helicopter parents, who take over-parenting to the next level. Rather than staying overhead in the air, these parents actively prepare the way for their children to succeed, cushioning every bump along the way.

    Their goal is to create a soft, even surface onto which their child will proceed, free from harm and worry. They get involved before problems reach their child, sometimes even going to immoral lengths, such as writing college papers for a child who's running out of time.

    One teacher told the Irish Times: “These days you would often hear from a mother or father insisting their child be put in the top math class, for example. Self-esteem (respect) is the buzzword (popular word). They feel it would harm their child's confidence. The irony is their self-esteem would be damaged far more by sending them into a class where they can't catch up with others.

    It's not children who are out of control. It's parents. There will come a point when these children won't have parents on which to depend, and then how are they going to function? It's frightening, too, to imagine these children becoming adults and attempting to raise families of their own. They would hardly be capable of teaching independence, confidence, work ethic, and discipline to their own children if they've never learned it themselves.

    At the end of the TIME article, Gibbs shared a wonderful quote from writer D.H. Lawrence, written in 1918: “How to begin to educate a child. First rule: leave him alone. Second rule: leave him alone. Third rule: leave him alone. That is the whole beginning.

    A new study says electronic toys are not helping babies learn.

    "Even if companies are marketing them as educational, they're not teaching the babies anything at this time," said Anna Sosa the study's author.

    Researchers listened to audio(声音的) recordings of parents playing with their babies aged 10 months to 16 months. The researchers compared the experiences when the children played with electronic toys, traditional toys such as blocks, or when the children looked at books. What they found is that parents talked less with their babies when the babies played with electronic toys.

    Why is this important? Research shows that how quickly children develop language is often based on what they hear from parents. When the infants played with electronic toys, parents said little to their children. But with traditional toys, such as blocks, parents shared the names and descriptions of the animals, colors and shapes as their children played. There was even more information given by parents as their babies looked at the pictures in books.

    Of course, there is no need for parents to throw out electronic toys, but they should look at their infants' play with such toys as entertainment, not a learning experience.

    Toy Industry Association spokeswoman Adrienne Appell responded to the study. She said it is important that parents make time to play with their children. "Playing is a way that kids can learn so much, not only cognitive(认知的) skills, but social and developmental skills," she said. She added that play should be balanced, including time for just "make believe" activities, as well as traditional and electronic toys.

    What do you do for fun in your spare time? Do you like reading? Do you often go to a book store? There is a store that is so different from others.

    The World's Smallest Bookstore, whose official name is just these three words, sits quietly about 100 miles northeast of Toronto.

    The bookstore is about 10 feet by 10 feet, so it is easy to imagine how tiny it really is. The bookstore is open 24 hours a day. Inside the bookstore are various books, especially literary books and classic authors' works. So if you are looking for something less popular, you may get a bit disappointed there.

    Another special feature of this bookstore is that each book only costs three dollars. All the expenses are paid on the honor system, which means buyers should make a note of what they've bought and leave their money by themselves. So the tools of the trade in this bookstore are quite simple: pens, papers, light bulbs and a label-maker.

    In order to catch passers-by's attention, the billboards (广告牌) of the bookstore are several times bigger than the store itself. With these large eye-catchers, many people are willing to stop by and have a visit.

    Many of you may have used Siri, a voice assistant of US tech company Apple. You only have to say "hey Siri" and it will answer to your command. However, we may be sacrificing our privacy to enjoy this convenience.

    According to a recent report by the Guardian, Siri can be accidentally triggered and start recording private conversations, such as discussions between doctors and patients. Some of these recordings are then given to workers outside the company to review.

    Apple claimed the data was used to help Siri improve, but users were not informed of this measure in the first place.

    Apple's Siri is not the only voice assistant to come under fire.

    In 2018, Alexa, a voice assistant developed by US tech company Amazon, recorded a private conversation between a couple and sent it to a stranger without their permission.

    These issues deepened concerns that tech companies are infringing users' rights of privacy.

    Many people have long feared that tech companies are listening and collecting data from private conversations, reported Forbes. Using this data, third party companies could then paint an accurate picture of users' habits and preferences in order to serve them more targeted advertisements, or even worse, sell this private data.

    Despite this risk, the popularity of voice assistant seems to be unstoppable.

    "In the near future, everything from your lighting to your air-conditioning to your refrigerator, your coffee maker, and even your toilet could be wired to a system controlled by voice," commented The Atlantic.

    Colin Horgan wrote on the blog site Medium that he believed people's daily lives will soon become a source of data.

    "The sounds of our homes, the symphony of life – laughing, crying, talking, shouting, sitting in silence – will no longer be considered memories, but data," he wrote.

    To deal with the issue, Blake Morgan, reporter for The Atlantic, believed that the answer is transparency.

    "All companies need to have messaging ready to explain to customers what they do with private data," she wrote on The Atlantic.

    Have you ever wondered how your favorite NBA team received its famous name? All NBA teams have an interesting story or a history behind their names. Some of the names reflect the city's culture or history, others came from previous owners and many were selected through "Name the Team" contests.

    For teams like Los Angeles and Utah, the names were not always a reflection of the city. Even though Los Angeles has no lakes, the Laker name has been a city treasure for almost 40 years. Before going to Los Angeles, the team originated in Minneapolis, Minnesota. In 1948, team officials chose the name for its direct relationship to the state's motto, "The Land of 10,000 Lakes." The team name went unchanged after moving to Los Angeles in 1960.

    Because Utah's team originated in New Orleans, Louisiana, it was called the Jazz. In 1974, New Orleans club officials chose the name to represent the city for its reputation as the "jazz capital of the world." The name stayed with the team even after finding a new home in Salt Lake City, Utah in 1979.

The Chicago Bull's original owner, Richard Klein, named the team the Bulls. He picked the name because a fighting bull is relentless, and never quits. Klein, who founded the club in1966, believed these qualities were necessary for a championship team and hoped his Chicago athletes would live up to the team name. A belief that Bulls—winner of the six NBA championships have definitely followed.

    In 1967, the Indian Pacers selected their team name in a different way from most other teams. Their decision was based on what they wanted to accomplish in the NBA. Team officials chose the Pacers name because the organization wanted to set the "pace" in professional basketball.
