For as long as humans have lived on the earth, they have made use of various forms of communication. Generally, this expression of thoughts and feelings has been in the form of oral speech. When there is a spoken language problem, communication can be carried out through sign language, in which gestures stand for letters, words, and ideas. Tourists and people unable to hear or speak have often had to turn to this form of expression. When gestures describe words or ideas, they can often be used internationally(各国之间地). When used for spelling words however, where each gesture stands for a single letter, people must share the same written language.
Body language sends ideas or thoughts by certain actions, either meaningfully or not. A wink(眨眼, 使眼色)can be a way of showing that the person is only joking. A nod means agreement, while shaking the head indicates disagreement.
Other forms of language can be found in Braille(a reading system of raised dots read with the fingertips used by the blind), signal flags, Morse code, and smoke signals. Road maps and picture signs also guide and warn people. While language is the most common form of communication, other systems and techniques also express human thoughts and feelings.

Scientists at Royal Holloway, University of London and Queen Mary, University of London have discovered that bees learn to fly the shortest possible route between flowers even if they discover the flowers in a different order. Bees are effectively solving the “traveling salesman problem”, and they are the first creatures found to do this.
The traveling salesman must find the shortest route that allows him to visit all locations on his route. Computers solve it by comparing the length of all possible routes and choosing the shortest, and it can keep computers busy for days. However, bees solve it without computer assistance using a brain the size of grass seed. Dr. Nigel Raine, from the School of Biological Sciences at Royal Holloway explains, “Bees solve traveling salesman problems every day. They visit flowers at multiple locations and because bees use lots of energy to fly, they find a route which keeps flying to a minimum. ”
The team used the computer to control artificial flowers to test whether bees would follow a route defined by the order in which they discovered the flowers or if they would find the shortest route. After exploring the location of the flowers, bees quickly learned to fly the shortest route.
As well as improving our understanding of how bees move around the landscape pollinating(授粉)crops and wild flowers, this research, which is due to be published in The American Naturalist, has other applications. Our lifestyle relies on networks such as traffic on the roads, information flow on the Web and business supply chains. By understanding how bees can solve their problems with such a tiny brain, we can improve our management of these everyday networks without needing lots of computer time. Dr. Raine adds, “Despite their tiny brains, bees are capable of extraordinary feats of behavior. We need to understand how they can solve the traveling salesman problem without a computer. ”

Students go to colleges and universities to have valuable experiences and learn to live in their own. Go to college often means having the opportunity to meet with different peoples from different parts of the country. They learn to communicating and co-operate with each other. For most students, we guess, it is the first time that they had been away home. They are faced by many new situations and have to learn to solve them independently, making decisions on our own and dealing with various things themselves. So colleges and universities help with them grow up.
You might notice something new in the next few years as you watch Disney programs: Starting in 2015, there won’t be any candy, sugary cereal or fast-food commercials aimed at kids.
The Walt Disney Company has become the first major media company to ban ads for junk food on its TV channels, radio stations and websites. It hopes this will stop kids from making poor food choices.
First Lady Michelle Obama called it a “game changer” that is sure to send a message to the rest of the children’s entertainment industry. “Just a few years ago, if you had told me or any other mom or dad in America that our kids wouldn’t see a single ad for junk food while they watched their favorite cartoons on a major TV network, we wouldn’t have believed you, ”said the First Lady, who heads a campaign to help stop child obesity.
The ban would apply to Disney-owned ABC stations as well as Radio Disney and Disney-owned websites aimed at families with young children. In addition, Disney plans to make changes to its kids’ menus at theme parks and resorts(度假胜地). Fast-food options will be replaced with healthier choices, such as smoothies(果汁), apples, vegetables and yogurt.
In addition to candy bars and fast-food meals, other foods that don’t meet Disney’s nutritional standards will be banned from the company’s kid-targeted media. Any cereal with 10 grams or more of sugar per serving will be off the air. There will be no ads for full meals of more than 600 calories. Juices with high levels of sugar and foods with too much salt will also be pulled.
Leslie Goodman, Disney’s senior vice-president of Corporate Citizenship, said a company that wants to advertise will need to show that it offers a range of healthy options.
Disney isn’t the only one pushing away unhealthy foods. Last week, New York City Mayor Michael Bloomberg suggested a ban on drinks over 16 ounces sold in movie theaters, restaurants and convenience stores in the Big Apple. He says large, sugary drinks are partly to blame for obesity.

Nearly all the tourists who come to southeast France make a tour to Monaco(摩纳哥), too. Lying near the French-Italian border, Monaco is not part of France, but a separate principality(公国), though it is surrounded by its greatest neighbour.
Monaco became a principality in the 16th century after being owned by a family member of a certain Italian king. The French and Italians, however, soon came to “protect” it one after another, until 1861, when it became its own master again.
Facing the blue Mediterranean(地中海), Monaco is mainly made up of two cities, Monaco, where the palace of the prince(王子)stands, and Monte Carlo(蒙特卡洛), which is a wonderful place for tourists. Every year, around half a million people from all parts of the world come to Monaco, nearly 25 times as much as its population.
Believe it or not, Monaco has no soldiers or policemen of its own. Law and order is kept by French police, and French stands for it in its foreign affairs, even the money used in Monaco is franc, too.

Think of London and you will probably remember the bright red double-decker buses. Think of Thailand’s capital city, Bangkok, and the noisy tuk-tuks may come to mind. Think of San Francisco and you might see the city’s cable cars.
Imagining what these cities would look like without those is difficult. They are symbols of these cities that make them different. However, these city symbols are not always so well loved by their city leaders. City leaders want what is best for their city, which often means the most modern transport.
In Bangkok, city leaders have banned(禁止)tuk-tuks because they consider them noisy and polluting. However, the ban has largely been unsuccessful as it has not changed Thai people’s love for the cheap tuk-tuks over taxis.
In London the city’s first ever mayor(市长)removed the red double-decker buses, which he thought were old fashioned. His plan worked, but Londoners were unhappy to lose the nice old buses they believed represented the best of their city. They made their unhappiness felt when the mayor came up for re-election. Most Londoners voted for his competitor, who promised to bring the bus back.
As for San Francisco, several cable cars are still in use but mainly as tourist attractions. They are too slow to be used for anything other than scenic trips.
City transport symbols may have a place in their city people’s hearts, but it seems they are increasingly out of step with the modern world. As Londoners have proved, their continued life depends on people’s willingness to fight for their survival.
