It is difficult for parents of nearly every family to teach their children to be responsible for housework, but with one of the following suggestions, you really can get your children to help at home.

    If you give your children the impression that they can never do anything quite right, then they will regard themselves as unfit or unable persons. Unless children believe they can succeed, they will never become totally independent.

    My daughter Carla's fifth-grade teacher made every child in her class feel special. When students received less than a prefect test score, she would point out what they had mastered and declared firmly they could learn what they had missed.

     You can use the same technique when you evaluate (评价) your child's work at home.

    Don't always scold and give lots of praise instead. Talk about what he has done right, not about what he hasn't done. If your child completes a difficult task, promise him a Sunday trip or a ball game with Dad.

    Learning is a process of trying and failing and trying and succeeding. If you teach your children not to fear a mistake of failure, they will learn faster and achieve success at last.

    Children grow quickly, especially their feet. But many families cannot buy new shoes each time a child needs them. As a result, about 300 million children around the world go barefoot. Those children risk picking up diseases and parasites from the soil.

    Kenton Lee, an American man invented The Shoe That Grows. He explains, “It grows in three places: the front, on the side and on the back. It can last up to five years. The bottom is rubber like tire rubber. The top is just high-quality leather. ”

    Lee says he got the idea for the shoe while working as a volunteer in an orphanage in Kenya. “I just remember a little girl who wore a pair of small shoes. The shoes were so small that she had to cut open the front of her shoes to let her toes stick out. And I just remember thinking, wouldn't it be nice if there were a pair of shoes that could grow with her feet？”

    However, Lee says it was not easy to turn his idea into a reality. Finally, in 2009 Lee founded a non-profit organization called Because International. In the office of Because International, Lee keeps a pair of his own shoes to help him remember his promise.

    A pair of shoes, he says, gives more than protection. It gives a child self-worth and more chances to succeed. “Because it's a small thing that really does make a big difference to keep them healthy and happy and having more chances to succeed.”

    Kenton Lee adds that his goal is to help get The Shoe That Grows to as many children as he can around the world.

    What do you usually do to comfort your friends when they are sad? You probably pat them on the shoulder, or give them a warm hug.

    We used to think that knowing when and how to comfort others was an ability that only humans have. But scientists have discovered that apes (猩猩) have this ability too.

    Two researchers from Emory University in Atlanta, US, went to an Ape Protection Centre in Congo to study bonobos (倭黑猩猩), which are closely related to humans.

    The researchers analyzed the bonobos' reactions (反应) after more than 370 cases of stressful situations, such as fights and losing temper, and found that some bonobos rushed to hug those that were screaming after being attacked, just like humans would have done.

    However, researchers found that not all bonobos were able to comfort others. In the protection center, many bonobos are orphans whose mothers were killed by hunters. They were found to be more worried in times of tension and have greater difficulty controlling their own emotions, making them worse at reaching out to help friends in need.

    "Orphans, who have not had the benefit of a mother helping them handling their emotions, are much worse at comforting others," Professor Frans de Waal told TheTelegraph. "Bonobos with moms were able to curb their negative emotional reactions more quickly. Therefore, they pay more attention to others."

    This pattern mirrors the way that human children have been found to react. Those who are good at handling their own emotions—for example, those who can calm themselves down more quickly after upsetting experiences—are usually better at expressing their concerns for others.

    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.

    Ask any new college graduate about his immediate goals, and it is likely that he will tell you he wants a job. But it turns out that today's students are not going to be satisfied with any job. According to the latest survey, making a difference through their work is essential (必要的) to young people's happiness.

    The survey found that 72 percent of graduating college seniors believe being able to have a positive social influence through their work is essential to their happiness. Making a difference is so important to them that 45 percent say they would take a 15-percent pay cut to work at an organization that has a social or environmental influence, and 58 percent say they would take a pay cut to work for an organization whose values are the same as their own.

    Besides this, the survey found that female students are far more likely to put social influence in first place than their male classmates, echoing the results of a former study showing that female maths and science majors are more likely to say they go into those fields to make a difference.

    One reason for the emphasis (强调) on improving the world probably has to do with the culture of colleges, which encourages students to connect their studies back to real-world problems. Students are used to discussing important social issues (问题) with their friends and professors, and doing something about them in class or through volunteer activities. Once students develop those habits, they don't shut them off when graduation rolls around.

When your boss calls and tells you to send $100,000 to a supplier, be on your toes. It could be a fake call. As if fake emails weren't enough, on the rise now is the deep fake audio (虚假音频) that can be cloned to sound almost real and perfect and is easy to create. "It's on the rise, and something to watch out for," says Vijay Balasubramaniyan, the CEO of a company called Pindrop.

Balasubramaniyan stated during a safety meeting how easy it is to use machine to create sentences that a person probably never said from recorded words. "All you need is five minutes of audio, and you can create fake audio," says Balasubramaniyan. Then, he showed a database (数据库) of voices, typed a sentence, and connected it to a famous people's name on the list. A few seconds later, he clicked "play", and it sounded quite real.

More costly are fake phone calls, where cheaters are able to fake the phone number of real contacts and make calls that result in workers sending off lots of money. He mentioned the example of a United Kingdom energy company in 2019 that got attacked by deep fake audio in a call that asked a worker to send $243,000 to a supplier. Reported by the Wall Street Journal, the worker was directed to pay it within an hour.

Balasubramaniyan says if you were to get that kind of call from a "boss" be doubtful and ask to call back right away to prove authenticity (真实性). Besides this, in his opinion, companies need to use more safety measures for keeping up with deep fake artificial intelligence (AI) that produces phone calls and software to check authenticity versus fake calls. "This is a threat that's waiting to happen," he says. "It's a very small number now, but it's very real."
