“A photograph that one has taken of oneself, typically with asmart phone or webcam and uploaded to a social media website” is the definitionof “selfie” in the Oxford English Dictionary. In fact, it wasn't even in thedictionary until August of last year. It earned its place there because peopleare now so obsessed with (对……痴迷) selfies ─ wetake them when we try on a new hat, play with our pets or when we meet a friendwhom we haven't seen in a while.

But is there any scientific explanation for this obsession?Well, you should probably ask James Kilner, a neuroscientist(神经系统科学家) atUniversity College London.

Through our lifetime we become experts at recognizing andinterpreting other people's faces and facial expressions. In contrast,according to Kilner, we have a very poor understanding of our own faces sincewe have little experience of looking at them ─ we just feel them most of thetime.

This has been proved in previous studies, according to the BBC.

Kilner found that most people chose the more attractive picture.This suggests that we tend to think of ourselves as better-looking than weactually are. To further test how we actually perceive our own faces,Kilner carried out another study. He showed people different versions of theirown portrait ─ the original, one that had been edited to look less attractiveand one that was made more attractive ─ and asked them to pick the versionwhich they thought looked most like them. They chose the more attractiveversion.

But what does it say about selfies? Well, isn't that obvious?Selfies give us the power to create a photograph ─ by taking it from variousangles, with different poses, using filters (滤色镜) and so on ─that better matches our expectations with our actual faces.

“You suddenly have control in a way that you don't have innon-virtual(非虚拟的)interactions," Kilner told the Canada-based CTV News. Selfies allow you“to keep taking pictures until you manage to take one you're happy with”, heexplained.

    A culture's values can be mirrored by its humor. Humor has been evaluated by many great minds such as Thomas Hobbes, who, In"On Nature", disliked humor," Laughter is nothing else but sudden glory arising from sudden thought of feeling far better than others." He thought humor to be a negative quality of human narrow-mindedness.

    However, Mordechai Gordon, PhD of Education, insists," Humor allows us to view the world from an angle that is amusing rather than serious." I agree with Gordon. Learning to look at the world through humor is important.

    In the United States, every four years an election occurs. Without humor as a way to express their feelings, how would Americans be willing to support the election? Television shows like "The Daily Show" have become important parts of American culture. They are mothering the masses by unconsciously inputting politics into our mouths. They make politics fun.

    Of course, politics is only one type of humor. Social humor helps people through the twists and turns of the human condition. American pop culture promotes an unhealthy self image. On the topic of self-image, Hari Kondabolu stands out. He has a joke about the popular musical group "The Pussycat Dolls", describing their hit song "Don't Cha" as a negative representation of women. He points out an obvious offence in American culture.

    A study from Loyola University of Maryland has shown that humor is one determining factor for selecting a mating partner. Amongst other things, mates look for an outstanding funny bone in a potential partner.

    Of course, humor is not always used for good purposes. Humor can be linked to vulgarity（粗俗）and racism, but, like everything else, it has potential to unite human beings by allowing us to laugh at ourselves, our failures and our connection with one another.

    Though life may seem tough and depressing at times, all I have to do is look in the mirror at my increased wrinkles（皱纹）to know that there is a comedy out there that even Chaplin wasn't aware of.

    With that in mind, remember to laugh with humanity and sometimes at humanity.

    John Smith was a very handsome young man but he was lazy. He had finished his education and was happy to sit in his room and listen to the radio all day long. In fact, he had been doing nothing for almost six months, which worried his father a lot. One day Mr. Smith decided that he had to do something. “Johnny, When I was your age I was working and supporting my ten brothers and sisters. I want you to go out and get a job.” So that was what he did. In fact, in the next three months, Johnny started ten jobs and was fired from ten jobs. He explained to his father.

    “They wanted me to be at work at 8:00 a. m. and told me to do all sorts of unpleasant things.”

    “I don't care how you do it,” Mr. Smith said. “Either you earn some money or move out of the house. I gave you one week's time.”

    In the next few days Johnny began to change. He still stayed in his room all day, but spent his time writing letters and reading through the newspapers. More and more posts began to arrive for him. He bought a new suit for himself and invited his parents to the theatre and for dinner afterwards at the most expensive restaurant in town. When his proud parents arrived home after their evening hour, a policeman was waiting at the front door.

    “John Smith,” he said as he handed him a piece of paper, “I'll see you in the court tomorrow.”

    When he got outside, Johnny told his parents everything. “When you told me to earn some money, I decided to put an advertisement in the newspaper saying, 'New way to money fast! Send me $ 5 and I'll tell you my secret.' When I received the money I wrote back telling people to do as I do.”

    Johnny was fined $250 by the court and was ordered to pay all the people back. As he left the court house feeling very ashamed, a newspaper man came up to him, “Young man, would you like to tell your story to my newspaper for $2,500?”

    Given that many people's moods (情绪)are regulated by the chemical action of chocolate, it was probably only a matter of time before somebody made the chocolate shop similar to a drugstore of Chinese medicine. Looking like a setting from the film Charlie&the Chocolate Factory, Singapore's Chocolate Research Facility (CRF) has over 100 varieties of chocolates, its founder is Chris Lee who grew up at his parents' comer store with one handalmost always in the jar of sweets.

    If the CRF seems to be a smart idea, that's because Lee is not merely a seasoned salesperson but also head of marketing department that has business relations with big names such as Levi's and Sony. That idea surely results in the imagination at work when it comes to making different flavored (味道) chocolates.

    The CRF's produce is “green”, made within the country and divided into 10 lines, with the Alcohol Series being the most popular. The exotic Series—with Sichuan pepper, red bean(豆), cheese and other flavors—also does well and is fun to taste. And for chocolate snobs, who think that they have a better knowledge of chocolate than others, the Connisseur Series uses cocoa beans from Togo, Cuba, Venezuela, and Ghana, among others.

    Abraham Lincoln, a self-taught lawyer, was elected 16th president of the United States in November 1860, shortly before the outbreak of the Civil War. Lincoln proved to be a smart military strategist and a competent leader: His Emancipation Proclamation (解放宣言) paved the way for slavery's abolition, while his Gettysburg Address stands as one of the most famous speeches in American history. In April 1865, with the Union on the brink of victory, Abraham Lincoln was killed; his untimely death made him a hero to the cause of liberty, and he is widely regarded as one of the greatest presidents in U.S. history.

    On January 20, 1981, Reagan took office. Only 69 days later he was shot by a would-be killer, but quickly recovered and returned to duty. His grace and wit during the dangerous incident caused his popularity to soar.

    At the end of his two terms in office, Ronald Reagan viewed with satisfaction the achievements of his innovative program known as the Reagan Revolution, which aimed to motivate the American people and reduce their reliance upon Government. He felt he had fulfilled his campaign pledge of 1980 to restore "the great, confident roar of American progress and growth and optimism."

    When George W. Bush, at the age of 54, became the 43rd president of the United States, it was only the second time in American history that a president's son went on to the White House. John Quincy Adams, elected the sixth president in 1824, was the son of John Adams, the second president. While John Adams had brought up his son to be president. George Bush, the 41st president, insisted he was surprised when the eldest of his six children became interested in politics, became governor of Texas, and then went on to the white House.

    Barack Obama served as the 44th President of the United States. His story is the American story—values from the heartland, a middle-class upbringing in a strong family, hard work and education as the means of getting ahead, and the belief that a life so blessed should be lived in service to others.

    With a father from Kenva and a mother from Kansas, President Obama was born in Hawaii on August 4, 1961. He was raised with help from his grandfather, who served in Patton's army, and his grandmother, who worked her way up from the secretarial pool to middle management at a bank.
