The American newspaper has been around for about three hundred years. In 1721, the printer James Franklin, Benjamin's older brother, started the New England Courant, and that was what we might recognize today as a real newspaper. He filled his paper with stories of adventure, articles on art, on famous people, and on all sorts of political subjects.

    Three centuries after the appearance of Franklin's Courant, few believe that newspapers in their present printed form will remain alive for long. Newspaper companies are losing advertisers, readers, market value, and, in some cases, their sense of purpose at a speed that would not have been imaginable just several years ago. The chief editor of the Times said recently, "At places where they gather, editors ask one another, 'How are you?', as if they have just come out of the hospital or a lost law case.” An article about the newspaper appeared on the website of the Guardian, under the headline “NOT DEAD YET.”

    Perhaps not, but the rise of the Internet , which has made the daily newspaper look slow and out of step with the world, has brought about a real sense of death. Some American newspapers have lost 42% of their market value in the past three years. The New York Times Company has seen its stock drop by 54% since the end of 2004, with much of the loss coming in the past year. A manager at Deutsche Bank suggested that stock-holders sell off their Times stock. The Washington Post Company has prevented the trouble only by changing part of its business to education; its testing and test-preparation service now brings in at least half the company's income.

    “When in Rome, do as the Romans do”, so when you want to do business in France, you have to get to know French culture, to make marketing plans, and to run your business by local laws.

    {#blank#}1{#/blank#}The French take great pride in their language, so anyone who does not speak it may run the risk of being disrespected by his French colleagues or business partners. Also, another reason why learning French is important is that it is a great way to show every possible French business partner that you care and respect their country's culture and language.

    There are obvious ways of greeting people in French. When you meet someone new, it's usual to shake his hand firmly and always look at the person in the eye.{#blank#}2{#/blank#}

    Dress well.{#blank#}3{#/blank#} Your business clothing is a reflection of your success and social status. Always try to be stylish. Women are advised to dress simply but elegantly. Wearing make-up is practiced widely by business women.

    The French are passionate about food, so lunches are common in doing business in France, which usually consist of an appetizer, main meal with wine, cheese, dessert and coffee, and normally take up to two hours{#blank#}4{#/blank#}

    Do not begin eating until the host says, “Bon appetite”. Pass dishes to the left, keep wrists above the table and try to eat everything on the plate{#blank#}5{#/blank#} This may suggest that you find the food tasteless. If eating in a restaurant, the person who invites always pays.

A. The French draw information about people based on their appearance.

B. This is a time for relationship building.

C. Maybe you have heard the expression.

D. Language should be the focus of anyone planning to do business in France.

E. Be careful with adding salt, pepper or sauces to your food.

F. When you meet a friend, kissing is common.

G. English and French are both spoken in formal occasions.

    The World Happiness Report, a United Nations agency report, measures (估量) how happy people are, and why. Norway is the happiest place on earth—beating neighbour Denmark from the number one position.

    Denmark, Iceland, Switzerland and Finland are among the top five, while the Central African Republic came last. Western Europe and North America took up most of the places at the top of table, with the US and UK at 14th and 19th respectively.

    The World Happiness Report mainly depends on asking a simple question of more than 1,000 people every year in more than 150 countries. “Imagine a ladder, with steps numbered from 0 at the bottom to 10 at the top,” the question asks. “The top of the ladder is the best possible life for you and the bottom of the ladder is the worst possible life for you. On which step of the ladder would you say you personally feel you stand at this time?”

    The average (平均的) result is the country's score—from Norway's 7.54 to the central African Republic's 2.69. But the report also tries to explain why one country is happier than another. It looks at reasons including economic strength, social support, freedom of choice, and generosity.

    This year's report also has a text titled “restoring (恢复) American happiness”, which examines why happiness levels in the United States are falling, despite continually-increasing economic improvement. “The United States can and should raise happiness by solving American's social problems—rising inequality and distrust—rather than focusing mainly on economic growth,” the authors said.

    Jeffrey Sachs, the director of the Sustainable Development Solutions Network, which published the report, said President Donald Trump's policies were likely to make things worse.

    The English language has a lot of words which can be used in many different ways and in many different expressions.

    One such example is the word matter. In fact, matter can mean just about anything. It could be one of the most useful words in the English language.

    Let's get to the heart of the matter—a matter of principle (原则).

    If someone says that you owe (欠) him $50, but you don't, a friend might say, "Well, you could pay him the $50. It's not that much money. Then you won't have to hear him say it anymore." But if you do not owe him the money, do not pay him the money. It's a matter of principle.

    There is another way to use the word matter. But be careful with your choice of words.

    If you ask someone, "What's the matter?" it shows you are worried about the other person. But saying, "What's the matter with you?" has a completely different meaning. And it usually sounds rude (粗鲁的). In fact, when you say, "What's the matter with you?" you are suggesting that the person did something wrong or stupid.

    Another expression that could sound rude is to say, "It doesn't matter to me." Here, it depends on the context, and how you say it.

    Let's say you tell someone that a friend just got a big raise at work. That person answers with, "It doesn't matter to me." Here, it means he or she does not care. And it sounds rude.

    But saying, "Oh, you pick where we eat dinner. It doesn't matter to me." does not sound rude. In this situation, "it doesn't matter" shows you are easy-going (随和的).

    No matter how you look at it and what you say, matter is a very useful word. And it's only a matter of time before you will become an expert on the use of matter.

    Scientists have created a scent(气味)-delivery system that releases a pleasant fragrance when you sweat. Apply it to your skin, and the more you sweat, the better you'll smell. That's because the perfume only gets released upon contact with moisture(湿气).

Chemists from Harvard University combined two compounds to create their new system. One chemical is alcohol-based. This is the nice-smelling perfume. The other chemical is an ionic liquid(离子性液体), which is a type of salt that is liquid at room temperature. Ionic liquids are made of ions—molecules(分子) that have lost or gained one or more electrons(电子). If the molecule loses electrons, it will have a positive charge(正电荷). If it gains electrons, it gets a negative charge. Ionic liquids contain the same number of positive and negative ions, which makes them neutral, with no overall electric charge. In general, ionic liquids have no smell.

    When the perfume and ionic liquid are mixed together, a chemical reaction occurs. This bonds the molecules to each other. The reaction also temporarily inactivates the perfume's molecules. So when applied to the skin, the new perfume has no scent in the beginning. But adding water or sweat breaks the bond between the molecules. That releases the scent into the air.

    "The rate of the release of the fragrance depends on how much you sweat, in other words, how much water is available," explains chemist Nimal Gunaratne from Harvard University, who led the research. "Sweat is like the command to let the fragrance go."

    Christian Quellet is a chemist who has worked in the perfume industry for a long time. He is now an independent consultant based in Switzerland. "Gunaratne's perfume opens the door to new developments and applications of fragrance controlled-release systems," he says. Controlled-release systems allow small quantities of some compounds that they hold to enter the environment slowly.

    The system also traps some chemicals in sweat that are responsible for the bad sweat smell. These compounds are called thiols (硫醇). Just as water does, thiols break apart the bond that ties the perfume to the ionic liquid. When this happens, the thiols attach to the ionic liquid and their bad scent is inactivated as the perfume had been. This means the water in sweat and its thiols are both able to release the fragrance from the newly developed perfume.
