New Orleans, Louisiana, was established as part of the French Empire in 1718.

    Its location on the east bank of the Mississippi River gave it control of the American hinerland and it became strategically important to many nations. It was transferred from France to Spain, returned to France, and finally sold by Napoleon to the United States in 1803. The city was the site of a famous battle fought in 1815 between the British, who hoped to control it, and the Americans under General Andrew Jackson.

    The riverbed of the Mississippi is constantly silting（淤积）and the river is now actually higher than the city. Levees hold back the river and giant pumps are used to move water from the city into the river.

    Although New Orleans has been a part of the United States for almost two centuries, its population takes great pride in its French heritage. Louisiana still retains parts of the Code Napoleon which, for many years, was its only law.

    New Orleans is carefree city and it boasts its hot, spicy Creole seafood and its native Dixieland Jazz. The Jackson Square neighborhood maintains its French colonial homes and in other sections are pre-Civil War mansions. Visitors are surprised to find that behind this interesting surface of yesteryear is a busy industrial and port city. Grain and coal come from the Midwest and foreign goods are unloaded here. New Orleans is no longer a sleepy Southern town—but it's still fun to visit.

    People are being lured(引诱)onto Facebook with the promise of a fun and free service without realizing they're paying for it by giving up large amounts of personal information. Facebook then attempts to make money by selling their data to advertisers that want to send targeted messages.

    Most Facebook users don't realize this is happening. Even if they know what the company is up to, they still have no idea what they're paying for Facebook, because people don't really know what their personal details are worth.

    The biggest problem, however, is that the company keeps changing the rules. Early on, you could keep everything private. That was the great thing about Facebook—you could create your own little private network. Last year, the company changed its privacy rules so that many things—your city, your photo, your friends' names—were set, by default(默认), to be shared with everyone on the Internet.

    According to Facebook's vice-- president Elliot Schrage, the company is simply making changes to improve its service, and if people don't share information, they have a “less satisfying experience.”

    Some critics think this is more about Facebook looking to make more money. Its original business model, which involved selling ads and putting them at the side of the page, totally failed. Who wants to look at ads when they're online connecting with their friends?

    The privacy issue has already landed Facebook in hot water in Washington. In April, Senator(议员) Charles Schumer called on Facebook to change its privacy policy. He also urged the Commission to set guidelines for social-networking sites. “I think the senators rightly communicated that we had not been clear about what the new products were and how people could choose to use them or not to use them,” Schrage admits.

    I suspect that whatever Facebook has done so far to invade our privacy, it's only the beginning, which is why I'm considering deactivating(撤销)my account. Facebook is a handy site, but I'm upset by the idea that my information is in the hands of people I don't know. That is too high a price to pay.

    Technology offers conveniences such as opening the garage door from your car or changing the television station without touching the TV.

    Now one American company is offering its employees a new convenience: a microchip implanted (植入) in their hands. Employees who have these chips can do all kinds of things just by waving their hands. Three Square Market is offering to implant microchips in all of their employees for free. Each chip costs $300 and Three Square Market will pay for the chip. Employees can volunteer to have the chips implanted in their hands. About 50 out of 80 employees have chosen to do so. The president of the company, his wife and their children are also getting chips implanted in their hands.

    The chip is about the size of a grain of rice. Implanting the chip only takes about a second and is said to hurt only very briefly. The chips go under the skin between the thumb and forefinger. With a chip in the hand, a person can enter the office building, buy food, sign into computers and more, simply by waving that hand near a scanner. The chips will be also used to identify employees. Employees who want convenience, but do not want to have a microchip implanted under their skin, can wear a wristband (腕带) or a ring with a chip instead. They can perform the same tasks with a wave of their hands as if they had an implanted chip.

    Three Square Market is the first company in the United States to offer to implant chips in its employees. Epicenter, a company in Sweden, has been implanting chips in its employees for a while.

    Three Square Market says the chip cannot track the employees. The company says scanners can read the chips only when they are within a few inches of them. “The chips protect against identity theft, similar, to credit cards.” The U.S. Food and Drug Administration approved the chips back in 2004, so they should be safe for humans, according to the company.

    In the future, people with the chips may be able to do more with them, even outside the office. Todd Westby is Chief Executive Officer of Three Square Market. He says, “Eventually, this technology will become standardized allowing you to use this as your passport, public transit, all purchasing opportunities, etc.”

    Have you ever wondered what the longest word in the English language is? Believe it or not, there's no simple answer to the question. You might think it would be as easy as opening a dictionary and looking for the longest word. However, it's far more complicated (复杂的) than that.

    Over time, many people have suggested many different words for the title of the longest word in English. How can that be? That's because the first thing that people have different opinions on is what should be considered a word. Some of the words were simply made up to be the longest! For example, there is one really famous long word that most kids know. It comes from Disney's movie Mary Poppins: supercalifragilisticexpialidocious, which means wonderful. But since that 34-letter word was made up simply to be sung as a song in a movie, should it count?

    How about long words that actually describe something in the world? Scientists have come up with several possible choices. The name of a virus(病毒) totals 1,185 letters. There's also a protein(蛋白质) whose name totals 1, 909 letters. Should these win the title? "Not so fast!" say some people. Are these words ever actually used? Can they even be pronounced? And are they meaningful just because they are made up to be long?

    If you're wondering about some long words in common English, here are some examples. Those words include uncharacteristically (20 letters), deinstitutionalization(22 letters) and counterrevolutionaries (also 22 letters) Or perhaps the word "smiles" is the longest word in English. Sure, it has only six letters, but there is a "mile between the first and the last letters!

    A large number of people enjoy listening to various types of music while they paint, write, or draw. Many believe that music helps creativity.

    However, an international study conducted by English and Swedish researchers is challenging that opinion. Psychologists from Lancaster University, The University of Gävle, and The University of Central Lancashire say that their findings show music actually blocks creativity.

    To come to their conclusions, researchers had participants( 参与者) complete verbal insight problems designed to inspire creativity while sitting in a quiet room, and then again while music played in the background. They found that background music “badly affected” the participants' ability to complete tasks related to verbal creativity.

    The tasks were simple word games. For example, participants were given three words, such as dress, dial, and flower. Then, they were asked to find a single word related to all three that could be combined to form a common phrase or word. The single word, in this case, would be "sun" (sundress, sunflower, etc).

    Participants completed the tasks in either a quiet room, or while exposed to three different types of music; music with unfamiliar words, instrumental music, or music with familiar words. "We found strong evidence of damaged performance when playing background music in comparison to quiet background conditions," says co-author Dr. Neil McLatchie of Lancaster University.

    To conclude, the findings challenge the popular view that music encourages creativity, and instead prove that music consistently disrupts creative performance in dealing with problems.

    Nature has provided us with many kinds of resources. It is like a great magician(魔术师), creating wonders on Earth. One of them is the Amazon rainforest, the world's largest and home to millions of plants and animals. Nicknamed" the lungs of our planet", it produces about one-fifth of Earth's oxygen. However, this wonderful natural wonder is now in danger.

    Thousands of fires have broken out in Brazil, endangering much of the rainforest. These flames have lasted several weeks and are believed to be the "most intense" in almost ten years, according to BBC News.

    The Amazon has seen a large number of fires in 2019. Between January and August, there were over 74,000 fires – the highest number since 2013, the BBC reported.

    Forest fires are common during the dry season, which runs from July to October. They are usually caused by natural events like lightning. However, most of the fires this year are believed to be caused by farmers, who use fire as a traditional part of tropical agriculture(农业) to clean land, reported CNN.

    "It's the best time to burn because the plants are dry. Farmers wait for the dry season and they start burning and clearing the areas so that their cattle can have grass," wrote CNN meteorologist Haley Brink.

    The disaster has raised concern(关注) around the world. The Amazon rainforest is important for preventing climate change, said the BBC, absorbing millions of tons of carbon annually. When trees are cut down or burned, the rainforest's ability to absorb carbon is reduced.

    Brazilian climate expert Carlos Nobre told Reuters he's worried. If more than 20 percent of the ecosystem is destroyed, the Amazon rainforest could reach a "tipping point (临界点)", where the thick jungle will turn into a tropical savannah(大草原).

    Nobre warned that it is not far off, with between 15 and 17 percent of the rainforest having already been destroyed.

    The Brazilian government has sent soldiers to fight the fires. Many people have offered their support and called for recovery efforts. For example, Tim Cook, CEO of Apple, said he wanted to donate money and US Actor Leonardo DiCaprio's environmental charity, Earth Alliance, created a donation fund to help deal with the disaster.

    The public are also encouraged to donate to charities concerned with rainforest protection. "Every little bit helps in a bad situation like this," commented Gizmodo.
