Common public speaking problems

    The use of "I feel", "I think" and "maybe"

    In the question-and-answer session of the speaking competition, many contestants began their answers with uncertain expressions like "I feel", "I guess", "I hear", "maybe" and "perhaps".

    These words show that the person is only speaking from his or her point of view. {#blank#}1{#/blank#} 

    Work on keeping your answers brief and to the point, {#blank#}2{#/blank#} . Instead of the empty-sounding "I guess", using facts, together with a clear conclusion based on those facts, is far more likely to be popular with an audience.

    Using only one speaking style

    Don't stick to the same tone. {#blank#}3{#/blank#} 

    For example, when they spoke about their dreams, some sounded romantic. Others used humor. Very few used several different styles together. Try mixing more than one style, rather than just sticking with the same one.

    Irresponsible answers

    Public speaking is different from personal conversations. You're responsible for your words. {#blank#}4{#/blank#} So you should think twice before you talk. Don't be like the student who, when asked about his opinion on book piracy（盗版）, started by saying he supported it.

    Talking around the topic rather than directly answering it

    You should focus on one point and give a clear solution. The key is to work out what question is being asked. Is it asking you to discuss a certain topic or to present your own point of view?

    Use one or two arguments together and give a strong conclusion. {#blank#}5{#/blank#} 

A. It can be boring. Try to mix it up.

B. Even though you want to answer quickly, you don't want to sound foolish.

C. Also work on delivering them with calmness and confidence.

D. Deliberate gestures and affected（做作的）expressions of feelings are improper in a successful speech.

E. Remember that judges are not judging you on whether they agree, but on your ability to say what you think clearly.

F. This lacks the support of facts and seems not to be reliable for the judges and audience.

G. Confidence is extremely important in public speaking as it lets a speaker sound more convincing.

    Christopher Thomas, 27, was a writer by night and a teacher by day when he noticed he was always tired and was losing weight fast. Diagnosed with diabetes (糖尿病), Thomas would need to inject himself with insulin (胰岛素) three times a day for the rest of his life or risk nerve damage, blindness, and even death. And if that weren't bad enough, he had no health insurance.

    After a month of feeling upset, Thomas decided he'd better find a way to fight back. He left Canton, Michigan for New York, got a job waiting tables, nicknamed himself the Diabetic Rockstar, and created diabeticrockstar.com, a free online community for diabetics and their loved ones—a place where over 1,100 people share personal stories, information, and resources.

    Jason Swencki's son, Kody, was diagnosed with type diabetes at six. Father and son visit the online children's forums (论坛) together most evenings. “Kody gets so excited, writing to kids from all over,” says Swencki, one of the site's volunteers. “They know what he's going through, so he doesn't feel alone.”

    Kody is anything but alone: Diabetes is now the seventh leading cause of death in the United States, with 24 million diagnosed cases. And more people are being diagnosed at younger ages.

    These days, Thomas's main focus is his charity (慈善机构), Fight It, which provides medicines and supplies to people—225 to date—who can't afford a diabetic's huge expen­ses. Fight－it.org has raised about $23,000—in products and in cash. In May, Thomas will hold the first annual Diabetic Rockstar Festival in the Caribbean.

    Even with a staff of 22 volunteers, Thomas often devotes up to 50 hours a week to his cause, while still doing his full­time job waiting tables. “Of the diabetes charities out there, most are putting money into finding a cure，” says Bentley Gubar, one of Rockstar's original members. “But Christopher is the only person I know saying people need help now.”

    “Long time no see” is a very interesting sentence. When I first read this sentence from an American friend's email, I laughed. I thought it was a perfect example of Chinglish.

    Obviously, it is a word-by-word literal translation of the Chinese greetings with a ruled English grammar and structure! Later on, my friend told me that it is a standard American greeting. I was too surprised to believe her. Her words could not convince me at all. So I did a research on google.com. To my surprise, there are over 60 thousand web pages containing “Long time no see.” This sentence has been widely used in emails, letters, newspapers, movies, books, or any other possible places. Though it is sort of informal, it is part of the language that Americans use daily. Ironically, if you type this phrase in Microsoft Word, the software will tell you that the grammar needs to be corrected.

    Nobody knows the origin of this Chinglish sentence. Some people believe that it came from Charlie Chan's movies. In the 1930s, Hollywood moviemakers successfully created a world wide famous Chinese detective named “Charlie Chan” on wide screens. Detective Chan likes to teach Americans some Chinese wisdom by quoting Confucius. “Long time no see” was his trademark. Soon after Charlie Chan, “Long time no see” became a popular phrase in the real world with thanks to the popularity of these movies.

    Some scholars refer to America as a huge pot of stew. All kinds of culture are mixed in the stew together, and they change the color and taste of each other. American Chinese, though a minority ethnic(少数民族的成员) group in the United States, is also contributing some changes to the stew! Language is usually the first thing to be influenced in the mixed stew.

    You can have some other examples than adoptions（采用）from Chinese, such as pizza from Italian, susi from Japanese, and déjà vu from French etc. There is a long list! Americans do not just simply borrow something from others. They will modify it and make it their own, so you would not be surprised to find a tofu and peanut butter hamburger in a restaurant, or to buy a bottle of iced Chinese green tea with honey in a grocery store. Since Americans appreciate Chinese culture more and more nowadays, I believe more Chinese words will become American English in the future. In this way the American stew keeps adding richness and flavor.

    If you want to convince the boss you deserve a pay rise or promotion, the solution could be simple—eat the same food as they do.Psychologists have discovered managers are much more likely to instantly trust us if we choose the same dishes as them.

    During experiments, discussions over wages and work conditions were much more successful if both sides chose to snack on the same treats.And shoppers were much more likely to buy a product advertised on TV by someone eating a similar food to them at the time.

    The reason is thought to be so­called similarity attraction theory—where people tend to like others who have similar tastes or habits to themselves.But this is believed to be one of the first studies highlighting the role of food in this relationship.Researchers at Chicago University in the US conducted a series of experiments to examine food's role in earning trust.

    In a test, participants were told to watch TV—where someone pretending to be a member of the public praised a certain product.The volunteers were given Kit Kat bars to nibble, while the TV people ate either a Kit Kat or grapes as they talked.

    The results showed viewers were much more likely to express an interest in buying the product if the TV showed the other person eating a Kit Kat too.

    The researchers added, “Although similarity in food consumption is not a sign of whether two people will get along, we find consumers treat this as such.They feel more trusting of those who consume as they do.It means people can immediately begin to feel friendship and develop a bond, leading to smoother transactions from the start.”

    Harley Street psychologist Dr.Lucy Atcheson said it was already known that wearing similar clothes could instantly create trust.But this was the first report that food had the same effect.She said, “This is really interesting.It makes sense as people feel they have common ground and can trust the other person.That means negotiations are more likely to be successful.”

    Technological change is everywhere and affects every aspect of life, mostly for the better. However, social changes brought about by new technology are often mistaken for a change in attitudes.

    An example at hand is the involvement of parents in the lives of their children who are attending college. Surveys (调查) on this topic suggests that parents today continue to be "very" or "somewhat" overly-protective even after their children move into college dormitories. The same surveys also indicate that the rate of parental involvement is greater today than it was a generation ago. This is usually interpreted as a sign that today's parents are trying to manage their children's lives past the point where this behavior is appropriate.

    However, greater parental involvement does not necessarily indicate that parents are failing to let go of their "adult" children.

    In the context (背景) of this discussion, it seems valuable to first find out the cause of change in the case of parents' involvement with their grown children. If parents of earlier generations had wanted to be in touch with their college-age children frequently, would this have been possible? Probably not. On the other hand, does the possibility of frequent communication today mean that the urge to do so wasn't present a generation ago? Many studies show that older parents - today's grandparents - would have called their children more often if the means and cost of doing so had not been a barrier.

    Furthermore, studies show that finances are the most frequent subject of communication between parents and their college children. The fact that college students are financially dependent on their parents is nothing new; nor are requests for more money to be sent from home. This phenomenon is neither good nor bad; it is a fact of college life, today and in the past.

    Thanks to the advanced technology, we live in an age of bettered communication. This has many implications well beyond the role that parents seem to play in the lives of their children who have left for college. But it is useful to bear in mind that all such changes come from the technology and not some imagined desire by parents to keep their children under their wings.

    Chocolate could soon be a thing of the past, after scientists warned that the cacao plant, from which chocolate is made, could be extinct within 32 years.

    Over half of the world's chocolate comes from just two countries in West Africa­Cote d'Ivoire and Ghana­where the temperature, rain, and humidity provide the perfect conditions for cacao to grow. But the threat of rising temperatures over the next three decades caused by climate change, is expected to result in a loss of water from the ground, which scientists say could upset this balance.

    According to the related data, a temperature rise of just 2.1℃ could spell an end for the chocolate industry worldwide by 2050. Farmers in the region are already considering moving cacao production areas thousands of feet uphill into mountainous area­much of which is currently preserved for wildlife. But a move of this scale could destroy ecosystems that are already under threat from illegal farming and deforestation.

    Part of the problem, according to Doug Hawkins, is that cacao farming methods have not changed for hundreds of years. "Unlike other tree crops that have benefited from the development of modern, high yielding strains and crop management techniques to realize their genetic potential, more than 90% of the global cocoa crop is produced by small farms with unimproved planting material," he said. "It means that we could be facing a chocolate decrease of 100,000 tons a year in the next few years."

    Now scientists at the University of California at Berkeley have teamed up with American candy company Mars to keep chocolate on the menu. Using the controversial(有争议的) gene-editing technology known as CRISPR they are trying to develop a type of the cacao plant capable of surviving in dryer, warmer climates. If the team's work on the cacao plant is successful, it could remove the need for farmers in West Africa to relocate to higher ground, and perhaps even allow cacao to be grown elsewhere in the world.
