Forgive the accidental. A sudden fall is humorous not because we like to see people fall, but because it surprises. Froma spilled（溢出）water glass in a meeting to Aunt Rae's teeth coming off in the Thanksgiving turkey, the embarrassment of accidents can be relieved by humor and a helping hand. After making sure that nobody's hurt, forgive accidents with a chuckle（咯咯地笑）rather than a scolding.

    Look for the unexpected. The kid whoused to look at you with his eyes closed during a test had the idea. Parents who serve green eggs and ham to their children on graduation day get the idea. Unexpected actions lighten an atmosphere and relax people.

    Learn to laugh with your kids. Most of what children say and do is funny. Help them learn that accidents are sometimes funny and sometimes occasions for joining in and helping another human being. By sharing laughs and attempting to explain humor, you develop your sense of humor, as well as help kids develop their own sense of humor.

    Where can you go to listen to important people talk about important subjects? BigThink.com is a new website that allows Internet users to discuss certain topics with world experts. Subjects discussed on BigThink include the environment, music and questions about happiness and personal identity. The website has been called a YouTube for thinkers. Victoria Brown and Peter Hopkins created BiThink.com They said that people needed an international place to communicate with each other and discuss the important issues (话题)of our times. On the BigThink website, when you click on (点击)a subject, you will find a video of a person talking about his or her ideas. For example, you can listen to United States Senator Ted Kennedy talking about education and other things. Besides, you can read the comments(评论) and questions written by other visitors to the website. More than one hundred experts have expressed their ideas on the website. BigThink's creators started the website by first getting famous people to agree to be videoed. They began by interviewing several well-known professors from Harvard University. Then they used the names of these professors to gain the trust of others and get them to take part in the project. The website says BigThink belongs to everyone. Its motto(格言) is: "We are what you think." So, go online and start thinking big.

    Do you love holidays but hate the fact that you put on weight (增加体重) after the holidays? You are not alone.

    Holidays are happy days with pleasure and delicious foods. Many people, however, are worried about the weight that comes along with these delicious foods.

    With proper planning, it is possible to control your weight. The idea is to enjoy the holidays but not to eat too much. You don't have to turn away from the foods that you enjoy. The following suggestions may help you.

    Do not miss meals. Before yon leave home for a feast(宴会), have a small, low-fat snack. This may help to keep you from getting too excited before delicious foods.

    Begin with clear soup, fruit or vegetables.

    A large glass of water before you eat may help you feel full.

    Use a small plate; a large plate will encourage you to have more than enough.

    Better not have high-fat foods. Dishes that look oily or creamy have much fat in them.

    Choose lean（瘦的） meat. Fill your plate with salad and green vegetables.

    If you have a sweet tooth, try mints (薄荷) and fruits. They don't have fat content as cream and chocolate.

    Don't let exercise take a break during the holidays. A 20-minute walk after a meal can help burn off excess calories (多余的热量).

    Many people have long dreamed of being able to fly around as simply as riding a bicycle. Yet the safety and strength of a flying bike was always a big problem. Over the past 10 years, developments in technology have moved the dream of personal flying vehicles closer to reality. Now, two groups of inventors say such vehicles may be available soon.

    The British company Malloy Aeronautics has developed a prototype (原型) of its flying bicycle. Grant Stapleton, marketing sales director of Malloy Aeronautics, says the Hoverbike is able to get in and out of small spaces very quickly." It can be moved across continents very quickly because it can be folded and packed," he adds.

    Mr. Stapleton says safety was the company's main concern. He says the designers solved the safety issue by using overlapping rotors to power the vehicle.

    The company is testing a full-size prototype of the Hoverbike, which will most likely be used first by the police and emergency rescue teams.

    In New Zealand, Martin Aircraft Company is also testing a full-size prototype of its personal flying device, called the Jetpack. It can fly for more than 30 minutes, up to 1, 000 meters high and reach a speed of 74 kilometers per hour.

    Peter Coker is the CEO of Martin Aircraft Company. He said the Jetpack "is built around safety from the start". In his words, "Reliability is the most important element of it. We have safety built into the actual structure itself, very similar to a Formula One racing car.

    The Jetpack uses a gasoline-powered engine that produces two powerful jet streams. Mr. Coker says it also has a parachute that would be used, if there should be an emergency. "It starts to work at very low altitude and actually saves both the aircraft and the pilot," he adds. Mr. Coker says the Jetpack will be ready for sale soon.

    Before the 1830s, most newspapers were sold through annual subscriptions in America, usually $8 to $10 a year. Today $8 or $10 seems a small amount of money, but at that time these amounts were forbidding to most citizens. Accordingly, newspapers were read almost only by rich people in politics or the trades. In addition, most newspapers had little in them that would appeal to a mass audience. They were dull and visually forbidding. But the revolution that was taking place in the 1830s would change all that.

    The trend, then, was toward the "penny paper" ­a term referring to papers made widely available to the public. It meant any inexpensive newspaper; perhaps more importantly it meant newspapers that could be bought in single copies on the street.

    This development did not take place overnight. It had been possible(but not easy)to buy single copies of newspapers before 1830, but this usually meant the reader had to go down to the printer's office to purchase a copy. Street sales were almost unknown. However, within a few years, street sales of newspapers would be commonplace in eastern cities. At first the price of single copies was seldom a penny­usually two or three cents was charged­and some of the older well­known papers charged five or six cents. But the phrase "penny paper" caught the public's fancy, and soon there would be papers that did indeed sell for only a penny.

    This new trend of newspapers for "the man on the street" did not begin well. Some of the early ventures(企业)were immediate failures. Publishers already in business, people who were owners of successful papers, had little desire to change the tradition. It took a few youthful and daring businessmen to get the ball rolling.
