Great speakers are not born but made. You too can become a good orator by taking up the public speaking courses. Those who are incapable of speaking in front of the public can't come up in their life. The art of public speaking must be practiced by everybody who wants to reach great heights in their career. A lot of public speaking courses are available on the Internet. Choosing the best course that is right for you may be difficult but not impossible.

    The basic motive of public speaking courses should be to train you to become a public speaker and improve your skills of delivering a public speech. The course should first educate you with the principles of public speaking and tell you how to overcome stress and anxiety. By overcoming fear, you will be able to deliver your presentation clearly to your audience.

    A speaker can have a great influence on the audience with his body language and your public speaking course should tell you the gestures on stage that can attract the audience. Non-verbal communication also has a major role to play in delivering a speech effectively to a group. Though body language is important, the content and the natural use of words are what the audience are closely caring about. Public speaking courses should give tips in using the right words at the right time.

    Even though you have prepared well, the real success of public speaking lies in the way your speech is delivered. Public speaking courses will train you to present the contents in a lively manner impressing the audience. Your presentation should be professional and stylish. You can add humor or interactive sessions (互动环节) to your presentation to gain the audience attraction.

    A new study, which was published in the American Journal of Preventive Medicine, found that heavy use of platforms such as Facebook and Snapchat was associated with feelings of being separated from society among young adults—basically the opposite of what we are led to believe.

    Study co-author Brian Primack and his team surveyed 1,787 U. S. adults aged 19 to 32 and asked them about their usage of 11 social media platforms. They also asked participants questions related to social isolation, such as how often they felt left out. The participants who reported spending the most time on social media—over two hours a day—had twice the odds of perceived（感知到的）social isolation than those who said they spent a half-hour per day or less on the same sites.

    According to Tom Kersting, psychotherapist and author of Disconnected, the key to understanding these results lies in our understanding of “connections.” “Humans are social —emotional beings, meaning that it is in our DNA to be connected, face-to-face, with other humans,” he told Reader's Digest. “Although people think being on social media all the time makes them 'connected' to others, they are actually 'disconnected,' because the more time one spends behind a screen, the less time one spend face-to-face.”

    “Part of the issue of loneliness is that the majority of people who use social media aren't just posting, they are also viewing,” Kersting continued. “They are spending a lot of time looking at everyone else's posts, where they are and what they are doing. The constant exposure to everyone else's 'perfect' life experiences causes feelings of being left out.”

    So what's the answer? It's simple, says Kersting. “The solution to this is resisting the temptation to look at everyone else's life. Just focus on your own life, where you're going, what you are grateful for, and what you want to accomplish in this world.”

    I became a magician by accident. When I was nine years old, I learned how to make a coin disappear. I'd read The Lord of the Rings and gone into the adult section of the library to be buried in fantasy literature but young enough to still hold out hope that you might find a book of real, actual magic in the library. The book I found taught basic techniques, and I tried to practice.

    At first the magic wasn't any good. It was just a trick—a bad trick. I spent hours each day running through the secret moves in front of the mirror. I dropped the coin over and over, a thousand times in a day, and after two weeks my mom got a carpet and placed it under the mirror to muffle (消音) the sound of the coin falling again and again.

    One day I made the coin disappear on the playground. We had been playing football and were standing in the field behind the school. A dozen people were watching. I showed the coin to everyone. Then it disappeared. The kids screamed. Everyone went crazy.

    A few years later, I staged an underwater escape in the river that flowed through the middle of the campus of the University of Iowa, where I went to school. I stood on a boat in the middle of the river wearing nothing but biking shorts. The sky was dead and gray, and the water was cold at the surface, and colder in the depths below.

    Technically, I succeeded. I jumped into the water, sank to the bottom, and escaped from the locks and the chains before swimming to the surface. But it didn't feel like a success.

    An “adulting conference” (AC)this week allowed Kentucky high school seniors the chance to learn how to change a tire, how to cook and other basic life skills—things that they may not have learned at home or in classes. A series of photos posted by Bullitt Central High School on social media shows students taking “adulting conference” are learning about personal finances, resumes and other essential skills at the event, which has been widely reported on the local and national news outlets.

    “I saw a Facebook post that parents passed around saying they needed a class in high school on taxes and cooking,” AC organizer Hardin told Louisville's WAVE 3 News. Those skills are taught at school theoretically, she said, but the event gave students a chance to fill in gaps in their knowledge.

    Students could choose to attend three workshops out of 11 total options, the school says. The workshops were held in cooperation with numerous community partners.

    Some young people have left home and graduated school without having those gaps filled, according to a report this week from CBS New York, which documented a trend of young people seeking outclasses to learn basic life skills.

    While attending a cooking class, 29-year-old Elena Toumaras told the station she's struggling with “simple things.”

    “I was so used to, when living at home, my mom always cooking,” she told the station.

    An“Adulting School” in Portland, Maine, aims to use a new online format to teach the youths skills like conflict resolution, sewing and appreciation for all, the station says.

    Students' financial literacy has been of particular concern to some experts, as financial education in schools has stagnated(停滞)in the U.S., with only 17 states requiring students to take classes in personal finance—a number that hasn't risen in years.

    “The majority of U.S. states are failing our students by declining to offer these fundamental courses which are critical to their financial stability and security later in life. And this will be changed.” Nan J. Morrison, president and CEO of the Council for Economic Education, told CNBC.

    Grown-ups are often surprised by how well they remember something they learned as children but have never practiced ever since. A man who has not had a chance to go swimming for years can still swim as well as ever when he gets back in the water. He can get on a bicycle after many years and still ride away. He can play catch and hit a ball as well as his son. A mother who has not thought about the words for remember the story of Cinderella or Goldilocks and the Three Bears.

    One explanation is the law of overlearning, which can be stated as follows: Once we have learned something, additional learning trials increase the length of time we will remember it.

    In childhood we usually continue to practice such skills as swimming, bicycle riding, and playing baseball long after we have learned them. We continue to listen to and remind ourselves of words such as "Twinkle, twinkle, little star" and childhood tales such as Cinderella and Goldilocks. We not only learn but overlearn.

    The multiplication tables(乘法口诀表)are an exception to the general rule that we forget rather quickly the things that we learn in school, because they are another of the things we overlearn in childhood.

    The law of overlearning explains why cramming (突击学习)for an examination, though it may result in a passing grade, is not a satisfactory way to learn a college course. By cramming, a student may learn the subject well enough to get by on the examination, but he is likely soon to forget almost everything he learned. A little overlearning, on the other hand, is really necessary for one's future development.

    The Broadcom MASTERS competition aims to find a balance between celebrating individual accomplishments and acknowledging that science seldom happens alone. The competition takes off when students from around the country are teamed up and have to solve a series of hands—on challenges in the spotlight.

    Nowadays, kids are fed with “the myth of the lone scientist”, so placing such challenges in the middle school period has a huge potential for impact. The focus on teambuilding skills gets students excited before more fears and stereotypes(成见)set in.

    The initial pool of qualified students comes from the participants in nation-wide science fairs. Those who score in the top 10％(about 10, 000 kids)have the qualification to apply. The judges select the top 300 young scientists, and that group is finally narrowed to 30 finalists.

    Selection at this stage is clearly an honor in itself, but it counts as step one for the finalists. They are then flown to Washington, D. C. and placed into teams of five for the hands-on part of the competition. Each team is made up of students with different talents and skills, including academic focus and experience.

    Unlike the science fairs, where most of the work takes place behind the scenes and students share a polished outcome, the hands-on challenges create a space where the work is the competition itself. The students take up a range of challenges in science, technology, engineering, math and so on. Each of the challenges will need the insight and skills of multiple team members.

    Judges observing the challenges aren't just looking for outcomes but also for leadership, teamwork and problem solving.

    The Broadcom MASTERS attracts increasing numbers of passionate and talented young people who are eager to take part in a program that helps them grow as scientists, engineers and inventors. It lets the students experience a sense of coming together with true peers. More importantly, it provides them with new skills to tackle future challenges.
