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.

    One of the traditions which is now a necessary part of Christmas is that of Father Christmas, or Santa Claus. According to the modern legend, he is a magical figure who visits all the children of the world during the night before Christmas Day, leaving presents, which they find the next morning. He flies through the night sky in a sledge pulled by reindeer, and enters houses by climbing down chimneys. This strange legend is based on the life of a man called Nicholas, but in fact we know very little about him. Historians think he was a Christian bishop（主教）in Turkey in about 285-350 A.D. One of the stories about him is that he helped three poor girls. No one would marry them because they were so poor.

    To provide them with money for their weddings, Nicholas secretly dropped some gold coins down the chimney of their house. After Nicholas died, he was made a saint（圣人）by the church. (The name Santa Claus thus comes from St Nicholas.) His feast day was celebrated in December, and parents started giving their children secret presents from St Nicholas. Over the years, this custom became part of our Christmas traditions.

    Recently, a psychologist has claimed that Father Christmas is “the perfect fantasy” for children. According to Professor Anthony Clare, children love the character of Father Christmas because he is like an ideal father: he loves children and gives them presents, but he never criticizes them, is never angry and children do not even need to thank him for presents. Other writers, however, point out that Father Christmas can be a frightening character to some children. Jane Bidder says that some children are terrified of this fat, bearded old man. It can certainly confuse many children. As presents, we warn our children to be careful of strangers and never to let them into the house, and yet we tell children that a strange man will come into their bedroom at night! Some children can become very worried about this idea and fear that he is a kind of burglar.

    Most children, however, understand from their parents and from the media that Father Christmas is basically a benign character, and look forward to his annual visit with joy and excitement.

    There's a new frontier in 3D printing that's beginning to come into focus: food. Recent development has made possible machines that print, cook, and serve foods on a mass scale. And the industry isn't stopping there.

    Food production

With a 3D printer, a cook can print complicated chocolate sculptures and beautiful pieces for decoration on a wedding cake. Not everybody can do that—it takes years of experience, but a printer makes it easy. A restaurant in Spain uses a Foodini to" re-create forms and pieces" of food that are" exactly the same,” freeing cooks to complete other tasks. In another restaurant, all of the dishes and desserts it serves are 3D-printed, rather than farm to table.

    Sustainability(可持续性)

    The global population is expected to grow to 9.6 billion by 2050, and some analysts estimate that food production will need to be raised by 50 percent to maintain current levels. Sustainability is becoming a necessity. 3D food printing could probably contribute to the solution. Some experts believe printers could use hydrocolloids( 水解胶体)from plentiful renewables like algae(藻类) and grass to replace the familiar ingredients(烹饪原 料). 3D printing can reduce fuel use and emissions. Grocery stores of the future might stock "food" that lasts years on end, freeing up shelf space and reducing transportation and storage requirements.

    Nutrition

    Future 3D food printers could make processed food healthier. Hod Lipson, a professor at Columbia University, said, "Food printing could allow consumers to print food with customized nutritional content, like vitamins. So instead of eating a piece of yesterday's bread from the supermarket, you'd eat something baked just for you on demand."

    Challenges

    Despite recent advancements in 3D food printing，the industry has many challenges to overcome. Currently, most ingredients must be changed to a paste( 糊状物)before a printer can use them, and the printing process is quite time-consuming, because ingredients interact with each other in very complex ways. On top of that, most of the 3D food printers now are restricted to dry ingredients, because meat and milk products may easily go bad. Some experts are doubtful about food printers, believing they are better suited for fast food restaurants than homes and high-end restaurants.

    German engineers Gottlieb Daimler and Karl Benz built the first successful gasoline engines in 1885.After 1900, however, the United States became a leader in automobile production.

    The first cars were handmade and very expensive. Only people in rich cities could afford them. The first company to make gasoline cars in the U.S. was the Duryea Motor Wagon Company. Then, in 1901, Ransom E. Olds Began mass-producing his car, the Oldsmobile. In 1913Henry Ford made great strides in the mass production of cars by using an assembly line in his factory. Mass production meant that each car was less expensive to make. Now car ownership was affordable for the average person. By 1916there were more than one million cars in the United States.

    The automobile gave people the freedom to travel anywhere there were passable roads. Families that lived great distance apart could travel by automobile to visit each other. People could visit places they had never seen before.

    Before the mass production of cars, people lived close to work. Their means of transportation included walking, riding a bicycle, using a horse and carriage, or taking a train. The automobile gave people the ability to live farther away from work. The result was that gradually people moved out of the cities to the less crowded suburbs.

    The automobile industry created millions of jobs. The jobs were not just in the auto factories, where the cars were assembled. Workers were needed to make auto parts, run gas stations and repair shops, and work at new motels and restaurants that served people who traveled by car. Jobs became available at car rental companies. People were needed to build roads. These jobs and many others still exist because of the automobile.

    When Chris moved in across the hall from Norma Cook four years ago in a Los Angeles-area apartment complex, the 31-year-old actor waved to his 85-year-old neighbor for a few weeks before finally knocking on her door and introducing himself. “The day I entered her apartment and spoke with her face to face was the day my life was changed forever,” Chris said.

    He learned that Cook had no family living in California and that she suffered from a long list of illnesses, including leukemia (白血病). The pair quickly became close friends, as Chris took her to doctor's appointments, cooked with her and they ran errands (差事) together. He shared their adventures on social media. But recently, Cook's health declined and she was in and out of the hospital several times. She once spent weeks in the hospital fighting pneumonia and breathing issues.  Eventually Cook was told by one of her doctors that she could no longer live at home unless she had 24-hour care. Because Cook had no money saved to pay her health care costs, Chris started a Go Fund Me account to help cover her bills.

    But caretakers are expensive and Cook quickly ran out of the $34,445 they raised. Knowing her days at home were limited, Chris invited Cook to move in with him to save money.“ She loves it! I do most of my work at home so I am here most of the time to care for her. It only made sense to both of us.” Chris wrote. “She is my adopted grandmother after all and I am her grandson she never had.”

    “Cook still has weekly hospice health care visits and regular visits from caregivers, so any funds raised cover those expenses,” he wrote. Though doctors say Cook's days are very limited, the pair are enjoying spending time together drinking champagne and snuggling with her cat, Hermes, who also made a move.

    “She does not want to change,” Chris told Today. “My apartment was the only place she would have moved. She has strong opinions about where she wants to carry out the rest of her days, and she wants to stay here.” Chris says he feels like the relationship was fate. “Moving her in....it feels as though it was meant to be all along, ” he said. “It's really fulfilling to be there for her.”
