The United States you may not know

The United States is the only superpower in the world, and it is far more advanced than any other country. However, we can't simply owe its 1 and prosperity to its lucky escape from the destruction of the two world wars. What other nations should 2 is the American spirit and its social system. 

The most obvious features of the American spirit are 3 and pragmatism (务实思想). Nearly 70% of the important inventions have been made in the US since the first industrial revolution. Since the US occupies such an important position in science and technology, naturally it has become the first superpower in the world. 

Americans are always 4 with what they have achieved, and they have an appetite for adventure over the love of 5 . European countries have been pursuing a reformist policy of "high tax and high welfare" since the 1960s, while only the US 6 the policy of "high risk and high return". 7 , the US has become the leader of the third industrial revolution (in technology of information, materials and biology). 

High salary is not the only 8 that the talents from other countries find in the United States. Some characteristics of American society should not be 9 . Family backgrounds and great wisdom in building connections and playing up to the boss, to which great importance is attached in other countries, are not so important to 10 development in the US. Most people are on the same starting line, and whether one can succeed or not depends on his own ability and hard work.

However, the American character is full of paradoxes (矛盾). The American people are both extremely romantic and pragmatic. The American is a(n) 11 people, but in every field there are workaholics. The Americans are open-minded but they are very conservative on certain matters. Since China's reform and opening-up to the outside world, many media in Western countries have greatly 12 their attitudes towards China. However, the American media are singing the same old tune against China as they were in the Cold War period. The Americans 13 freedom, but their government is very fond of interfering in other countries' internal affairs. What's most puzzling is that the Americans 14 authority, but they highly respect the laws and regulations of the society. Therefore, in such a nation that values personal liberty, the society can still be kept in good order and operate with high 15 . Is it odd? No one can provide a satisfactory answer.

    Getting on the school bus, like the possible dangers around the home, getting on the school bus can also bring its own set of dangers. There are several important safety measures that parents should be aware of when it comes to bus safety.

    Parents should always make sure that someone is taking charge of children at the bus stop to make certain clear ground rules which are in place and are being followed—particularly rules that forbid horseplay in and around the street.

    Teach children to ask the bus driver for help in picking up anything they may have dropped around the bus, as children getting dropped articles are often hit by the bus or another vehicle because they are not seen by the bus driver or by oncoming traffic.

    Children should be asked to take five large steps away from the bus when they get it off, and make sure that the bus driver can see you and look you directly in the eyes to signal it is OK to cross the street. It is still very important that children also look both ways as they cross the street.

    Inform children that they must never speak to any stranger who talks with them first and that they must never accept a ride from any person unless their parents tell them directly that it is OK. Teach kids that adults should ask other adults for help, not kids. If an adult asks a kid for help, that child should get another adult.

    If for any reason a child feels uncomfortable or unsafe at the bus stop they need to bring it to a parent's or caregiver's attention.

Remember, planning ahead is always the best safety measure. Follow these rules and your family will be off danger!

    A disease called “Panama” is threatening supplies of the world's most popular fruit—banana.Two years ago,the United Nations warned that the "Panama disease" could destroy "much of the world's banana crop."Since then,things have not gotten better.A new outbreak was discovered last year in Australia.The disease started in Asia in the 1990s, and later spread to Africa and the Middle East.

    World health officials worry the disease could travel to Latin America,one of the top banana producers in the world.All this is a big concern because bananas are an important source of income and nutrients for millions of people.They are grown in 135 tropical nations.The United Nations lists bananas as one of the most important foods, along with rice,wheat and corn.

    Randy Ploetz is a professor at the Tropical Research & Educational Center at the University of Florida.Many consider him as America's top banana expert.As he explained,Panama disease affects the Cavendish banana.The Cavendish is one of more than 500 kinds of bananas.But it is the most popular.

    “The industry is waking up to the problem,”Ploetz said.“They are pretty scared.”He was speaking Thursday by telephone from Miami,Florida,where he is among 1,000 people attending the International Banana Congress.The meeting was supposed to take place in Costa Rica,but was moved at the last minute.There were concerns banana growers could spread Panama disease from dirt collected on their shoes,Ploetz said.

    Ploetz said reports that Cavendish banana production could end are not correct.But if the disease spreads to Latin America,it could hurt the world's economy along with food supplies for millions of people.Still,he said there is reason for hope.Scientists in Australia are working on a genetically engineered banana that might not be at risk of getting Panama disease.

    Angel Garcia Crespo is a computer engineer at Carlos III University of Madrid in Spain. His group has invented a new way for deaf-blind people to "watch" TV. The idea for the technology grew out of previous work by his group. The team had already worked on making audiovisual(视听的) materials accessible to people with either vision or hearing disabilities. But the group wanted to help people with both challenges. So they asked some deaf-blind people what would help.

    In addition to relying on their sense of touch to communicate, deaf-blind people can also get and send information with a Braille line. The Braille system uses patterns of raised dots to stand for letters and numbers. A Braille line is an electronic machine with a changeable Braille display. Dots rise up or drop down based on the information sent to the machine.

    Now the new system changes TV signals to data a Braille line can use. "The key to the system is the possibility of using subtitles(字幕) to collect TV information, " Garcia Crespo explains. "Subtitles travel with the image(影像) and the audio in electromagnetic waves we don't see. But an electronic system can keep those waves. "

    First, a computer program, or app, pulls out the subtitles and visual descriptions from the broadcast signal. The system then combines the information and changes both into data for Braille.

    Now another app gets to work, which sends the data out to people's Braille lines on demand. "This is done in real time, in less than a second," Garcia Crespo says. This lets a deaf-blind person "watch" TV as it's broadcast. The system will work with various Braille lines, as long as there's a bluetooth connection available. Now, the system is only used in Europe, and it should soon be available in the US.

    For many of us, summertime means road trips to the beach or mountains, or at the very least some additional dust and bird poop on the exterior of our vehicles. The extra dirt leads us to do one of two things: wash our car in the driveway or head to the car wash. But which choice is better for the environment?

    The main concerns with either choice are the amount of fresh water being used and the types of chemicals used to remove the dirt. Both of these concerns can be closely monitored when washing the car at home, says Katy Gresh, spokeswoman for the Southwest Region of the Pennsylvania Department of Environmental Protection. She advises car owners to put aside a set amount of water for the entire wash. "It's just like brushing your teeth," she says, "You don't want to leave the water running of more than you need for the job." But even following this advice comes with an environmental risk: Washing your car in the driveway or street flushes the dirty water into storm drains.

    John Schombert, executive director of 3 Rivers Wet Weather, his organization works to educate the public about storm sewers (下水道) and water runoff, keeping this untreated water from entering the Allegheny region's waterways. "We ask people to, consider washing their cars on lawns or other permeable (透水的) surfaces where the water gets absorbed," Schombert says. "Soil can break down and help filter (过滤) those things," Schombert says. "Storm sewers are not made for waste disposal." Even when car owners use natural soaps to wash their cars, which Schombert says are probably ineffective at breaking down grease anyway.

    The commercial car wash down the street knows full well the rules regarding wastewater in storm sewers. According to the International Carwash Association (ICA), professional car washes must use water reclamation systems. These mandated processes not only keep the dirty water out of storm sewers and regular water treatment systems, but they also work to reduce water usage at commercial facilities.
