Why is pink or purple a color for girls and blue or brown for boys?

The answer depends largely on cultural values as well as personal experiences. To the Egyptians, green was a color that represented the hope and joy of spring, while for Muslims, it means heaven. Red is a symbol of good luck in many cultures. In China, children are given money in a red envelope to bring good fortune in the New Year. For many nations, blue is a symbol of protection and religious beliefs. Greek people often wear a blue necklace hoping to protect themselves against evils (灾祸).

People’s choice of colors is also influenced by their bodies’ reactions (反应) toward them. Green is said to be the most restful color. It has the ability to reduce pain and relax people both mentally and physically. People who work in green environment have been found to have fewer stomachaches.

Red can cause a person’s blood pressure to rise and increase people’s appetites (食欲). Many decorators will include different shades of red in the restaurant. Similarly, many commercial (商业的)websites will have a red “Buy Now” button because red is a color that easily catches a person’s eye.

Blue is another calming color. Unlike red, blue can cause people to lose appetite. So if you want to eat less, some suggest that eating from blue plates can help.

The next time you are deciding on what to wear or what color to decorate your room, think about the color carefully.

Frank Lloyd Wright is often called the father of American modern architecture.He designed buildings and homes across the United States for more than 70 years.He created most of his works from 1900 through the 1950s,but his open-living spaces and imaginative designs still appear very modern today.

Last week,the United States nominated(提名)10 of his buildings for the UN Educational,Scientific,and Cultural Organization—or UNESCO—the World Heritage List.The World Heritage List recognizes the most,important cultural and natural sites worldwide.

The 10 buildings,titled.“Key Works of Modern Architecture by Frank Lloyd Wright,”were built between 1906 and 1969.They include several of his personal homes and studios,churches,government buildings,private residences,and one very famous museum—New York City’s Guggenheim Museum.

The Solomon R.Guggenheim Museum is one of the most visited sites in New York City.About one million people visit it every year.Frank Lloyd Wright worked on it from 1943 to 1959.It was designed to create a new type of space for new types of art.The museum remains an international symbol of modern architecture that represents Wright’s unique design.

Many of Mr.Wright’s modern buildings and homes in the U.S.Midwest have also become symbols of modern American architecture.Richard Longstreth is the president of the Frank Lloyd Wright Building Conservancy.He calls Mr.Wrisht“the father of modern architecture,fundamentally redefining the nature of form and space during the early 20th century that would have enduring impacts of modern architecture worldwide.”

The UNESCO World Heritage Committee will announce its decision in mid-2016.If Frank Lloyd Wright’s 10 buildings were chosen for the list,they would be the first World Heritage listings for modem U.S.architecture.The World Heritage List already includes 22 other American sites,including the Grand Canyon,Yellowstone National Park and the Statue of Liberty.

Children of America are getting fatter every time. 13% of the children at the age of 6 to 11 are overweight(too fat).

When we look at the children's lives today in the USA, we can see the root(origin)of the problem----sports and foods. Young children like sports but they don't have enough around the start of high school. That's especially true for girls. Meanwhile, to make matters worse, schools are becoming much more interested in sports teams. So children are not able to get enough exercise just when they need it the most. There is also the food problem. Children get most of their calories at restaurants or parties or somewhere else away from home. They often drink too many Cokes. Parents have a lot of fears about telling a child he needs to lose weight-- they are afraid it will push a child into an eating disorder. Some parents fear that pushing children to lose weight means their children will think they're not good enough, or not loved because of their weight. Parents need to come to terms with the fact that the family is very important to the children. The most useful program for children is called "family weight control". This is good news. Mom and Dad, even if they don't have weight problems, have to go through the same program as their children and learn how to get some exercise and how to eat healthily.

THE idea came to Ralph Liedert while he was sweating in the Californian sunshine, having been standing with his daughter for over an hour in a queue for a ride at Disneyland. What, he thought, if his T-shirt had a cooling system he could turn on, at the tap of a smart phone app, when he needed it. Luckily, Mr Liedert does have the means to make the dream reality, for he works at the VTT Technical Research Centre of Finland, as one of a team there studying the rapidly growing field of microfluidics (微流控技术).

Cooling vests already exist (used by racing drivers, motorcyclists and people who work in hot conditions). But the tubes through which the cooling water is being pumped, and the vests’ need to be connected to outside units that cool this water, make them huge and clumsy. Mr Liedert thought VTT’s microfluidics department could do things better.

As its name suggests, microfluidics is the art of building devices that handle tiny amounts of liquid. Inkjet-printer cartridges (喷墨打印机墨盒) are a familiar example. Less familiar, but also important, are “labs-on-a-chip” (芯片实验室). These are tiny analytical devices that transport fluids such as blood through channels half a millimetre or less in diameter (直径), in order to carry them into what holds analytical reagents (试剂). Sensors, then detect the resulting reactions and provide an instant analysis of a sample (样本). Designing labs-on-a-chip is the VTT microfluidics department’s day job. One of its chips, for example, can tell whether water is affected by the bacteria that cause Legionnaires’ disease.

The department’s biggest contribution to the field, though, is to have developed a way of printing microfluidic channels onto large rolls of thin, flexible plastic. It works by passing the plastic between two heated rollers, one of which contains raised outlines of the required channels. As the rollers squeeze the plastic they create a pattern of channels into one surface. A second plastic film is then melted over the top as a cover. This process might, thought Mr Liedert, be suitable for printing a microfluidic cloth that was thin enough and pleasant enough to wear as a cooling vest.

The group’s first model showed that such a material could indeed be made and used to circulate cooled water. They are also looking at ways the water being circulated through the microchannels might be cooled. They have identified two. One uses a small heat-exchanger, the details of which they are keeping secret at this stage. The other employs evaporation (蒸发). It thus works in the same way that heat from circulating blood is removed by the evaporation of sweat.

Whichever cooling system is applied, the electronics needed to power and control it would be shrunk into a small package contained on the back of the vest. This could be operated by hand or, as Mr Liedert originally envisaged in his Californian queue, by a wireless link to a smart phone. Moreover, what can cool down can also, if run in an opposite way, warm up. In Finland, where winter temperatures fall as far as -50°C, that might be the technology’s killer app.
