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.

    A cellphone is one of the few things that we hold close to our faces all the time, and yet it could possibly explode - this is what made the recent Samsung's Galaxy Note 7 smart-phone accidents so shocking.

   According to technology news website The Verge, flawed（有瑕疵的）phone batteries might be to blame.

    Even if you are not a science student, you probably know that it is common sense that the anode (the negative（负的）end of the battery) and the cathode (the positive end) should never touch. If they do, the battery will short-circuit（短路）, causing a powerful electrical reaction that can destroy the battery and cause a fire.

    This is why all lithium-ion（锂离子）batteries - the kind that can be found in many of our devices like tablets and cameras - have a separator layer inside to stop the two ends from touching one another.

    But somehow, the separators in some of the Samsung phones broke, causing explosions.

    Overcharging is another problem that can make batteries heat up quickly. Fortunately, most batteries are designed to be able to automatically stop charging once they are fully charged. But again, this somehow failed to happen in some of the Samsung phones.

    The two “somehows” may sound random（随机的）and hard to explain. But they actually both come from the fact that phone producers have been pushing the limits of batteries to meet customers' demand for a longer battery life.

    According to Lynden Archer, a materials scientist at Cornell University, US, we have already achieved 90 percent of the battery life possible from a lithium-ion battery. Customers' demand that their devices get thinner has also given producers little choice but to try to put more power into thinner batteries.

     “The more energy you put into a box, the more dangerous it's going to be,” Billy Wu, a lecturer at Imperial College London, told The Guardian.

    A thinner battery also means producers have to use thinner material for separators, and thinner material has more chance of breaking.

    In Hollywood, as in war, truth is often the first casualty. Stories told on screen demand heroes, devils and a clear plot line. Real life, on the other hand, tends to get messy—the lines between good and bad often cross. Two years ago, director Oliver Stone was severely criticized in the press for playing fast and loose with certain facts in JFK. Jim Sheridan's In the Name of the Father has largely escaped such criticism in the U.S., but only because Americans are unfamiliar with the story it is based on.In Britain,where people have lived with the case of the Guildford Four for 20 years,the film's reception has been considerably stormier.

    The movie tells the tale of Gerry Conlon,who along with three other youths was falsely accused of killing five people in a 1974 I.R.A.bombing of two pubs in Guildford,England.The four—three men and a woman—served 14 years in prison before their convictions（定罪）were overturned. Seven friends and relatives of Conlon's (the Maguire Seven),including his father,also served many years on false charges of having made the bombs.

    Though Sheridan never set out to make a documentary,he has been attacked for needlessly twisting the facts of the case.The film,for instance,shows the Maguire Seven on trial with the Guildford Four,though the cases were tried separately.In some of its most affecting scenes,it shows Conlon,played by Daniel Day-Lewis,sharing a jail cell with his father,though the two were often not even in the same prison.A grand and heroic part is carved for actress Emma Thompson,playing Conlon's lawyer,Gareth Peirce,but in reality Peirce was a minor figure and another lawyer, Alastair Logan,deserves most of the credit for freeing the Four.An important scene in which Peirce steals a crucial piece of evidence from a police file was fabricated for the film;it was a police investigation that uncovered the buried evidence of Conlon's innocence.

    Sheridan insists that he was seeking an "emotional honesty" and that the real subject of his film was a son's changing relationship with his father.But if that was his intended subject,say some close to the case,the director should have used someone else's story."The truth is that Gerry Conlon had very little time for his father,"says Sean Smyth,an uncle."It's a good film,well acted and everything,"admits Conlon's aunt,Anne Maguire."But I think if they'd put more of the true facts in,it would have been a much more powerful film."

    Every year on April 1, April Fools' Day is celebrated in many countries around the world. In France, it's called "Poisson d' Avril" or "Fish of April." In Scotland, the holiday is often called "Gowkie Day." In Iraq, the holiday is called Kithbet Neesan or "April Lie."

    History experts say people have celebrated April Fools' Day for a long time. Some believe the tradition comes from the ancient Romans more than two thousand years ago. It was a day of playing games and pretending to be someone else.

    Others say the day for fooling began in France in 1564, when King Charles changed the yearly calendar. He moved New Year's Day from April 1 to January 1. Many people did not know about the change because of communication problems back then. Some people continued to celebrate New Year's Day on April 1. Other people called them April Fools and played jokes on them.

    In the United States, April Fools' Day is just a day of joking and playing tricks on friends. These kinds of jokes are also called pranks. These jokes typically end in the prankster shouting "April Fools'!"

    Simple pranks, like telling a friend a funny lie or making prank phone calls, are still common. But, major companies also get in on April Fools' Day fun in a much bigger way. A few years ago, on April 1, Starbucks announced it was introducing new coffee cup sizes -- Plenta and Micra. The very large cups, bigger than a human head, remained useful for customers even after finishing all that coffee. According to Starbucks, the cups could be used as a rain hat, a pot for plants, or a lampshade.

    It did not take long for customers to catch on to the prank! More and more people use social media or smart phone apps to play pranks on their friends on April Fools' Day. One very annoying smart phone app, Cat Facts, sends funny facts about cats to your friends' phones, every day.

    How many times do you check your Facebook page in a day to see whether your latest post has got another “like” or “thumbs(拇指) up”?

    Although you might be embarrassed to admit how many times you do this, don't worry—psychological findings have shown it's completely normal. In fact, the pleasure we derive from receiving a “like” is equal to that of eating chocolate or winning money, and we can't help wanting more. According to the findings, which observed 32 teens aged between 13 and 18, the feedback circuit (反馈回路) in the teens' brains is particularly sensitive, and the “social” and “visual” parts of their brains were active when they received “likes” on the social network. The research also showed that though the thumbs up might come from complete strangers, the good they derive from them worked all the same.

    So, does it mean we should try our best to win as many thumbs up as possible? Not necessarily so if we know the reasons behind our desire for attention. In “why do people long for attention” by M. Farouk Radwan, he explained several cases in which people naturally longed for attention. Radwan said people who were an only child, who were used to being the center of attention in their house, may try to copy these conditions. Feeling “overlooked and unappreciated” might also lead you to long for attention. Other times, the state of being jealous, or wanting to cover your mistakes may also contribute to such longings.

    In fact, too much desire for attention can create anxiety, and in turn ruin your happiness even when you get it. So what can we do about it? The answer is quite simple. “If people could adopt goals not focused on their own self-esteem（自尊）but on something larger than their self, such as what they can create or contribute to others, they would be less sensitive to some of the negative effects of pursuing self-esteem,” wrote psychology professor Jennifer Crocker.

    So perhaps the answer to our addiction to “likes” is simply to focus on something larger than ourselves—a hard, but a worthy one.

    It was the last day of the final examination in a college. On the steps of building, a group of engineering students were waiting for the last exam. On their faces was confidence.

    They knew the exam would be easy. The professor (教授) had said they could bring any books or notes during the test.

    Right after they came into the classroom, the professor handed out the papers. There were only five questions on it.

    Three hours passed. Then the professor began to collect the papers. The students no longer looked confident. On their faces was nervous expression. The professor watched the worried faces before him, and then asked, "How many of you have completed all five questions?" No hand was raised. "How many of you have answered four?" Still no hands. "Three? Two?" The students moved restlessly in their seats. "One, then? Certainly somebody has finished one." But the class kept silent. The professor said, "That is exactly what I expected. I just want to make you know clearly that even though you have completed four years of engineering, there are still many things about the subject you don't know. These questions you could not answer are common in everyday practice." Then, smiling, he added, "You will all pass this course, but remember, your education has just begun."

    The years have obscured the name of this professor, but not the lesson he taught.
