A man once said how useless it was to put advertisements in the newspapers．“last week, ”said he, “my umbrella was stolen from a London church．As it was a present, I spent twice its worth in advertising, but didn't get it back．”

    “How did you write your advertisement?” asked one of the listeners, a merchant．

“Here it is,” said the man, taking out of his pocket a slip cut from a newspaper．The other man took it and read, “Lost from the City Church last Sunday evening, a black silk umbrella．The gentleman who finds it will receive ten shillings on leaving it at No.10 Broad Street．”

    “Now, ”Said the merchant, “I often advertise, and find that it pays me well ． But the way in which an advertisement is expressed is of extreme importance．Let us try for your umbrella again, and if it fails, I'll buy you a new one．”

The merchant then took a slip of paper out of his pocket and wrote：“If the man who was seen to take an umbrella from the City Church last Sunday evening doesn't wish to get into trouble, he will return the umbrella to No.10 Broad Street．He is well known．”

    This appeared in the paper, and on the following morning, the man was astonished when he opened the front door．In the doorway lay at least twelve umbrellas of all sizes and colors that had been thrown, and his own was among them．Many of them had notes fastened to them saying that they had been taken by mistake, and begging the loser not to say anything about the matter．

    Rome wasn't built in a day, and the Internet didn't come out of a golden egg. Many of today's creations were not born of people who had creative ideas, but who did not stop at simply having an idea. They took one brick of capital (资本), another brick of knowledge, perhaps a brick or two of family and friends, and built their empires (帝国) brick by brick.

    If you want to build an online empire, you cannot settle for simply having a website full of articles, or a website full of pictures—there are already thousands of sites like that, so you need to come up with something new and creative.

    So if you are starting to build something up, ask yourself: what do you really want to do, and what are you really good at? Believe it or not, you can make money at something that you are an expert in, and you need to know what that is.

    Remember, having an online empire does not mean that you have to do it alone. You can take your friends along with you. Having a friend advertise your services online is a good way to attract more visitors to your empire.

    Building an online empire, you will have to be prepared to not only come up with creative ideas, but to carry your ideas through. Talk to people who have already succeeded in building their own empires. Talk to people who are struggling. Join a mailing list that will help you get through your struggle to achieve your goal.

    As you move forward, you will find that you can help other people, and you will have a good many stories to tell—not to mention a lot of money in the bank.

    If you learn the real secrets of creating a long term stable (稳定的) online business then you will have enough money to retire on.

    The fried foods, salty snacks and meat are major foods of the Western diet, which account for about 30 percent of heart attack risk across the world. Meanwhile, a diet rich in fruits and vegetables, the so called "Prudent" diet, can lower the risk of heart attack, according to a study.

    The research which looked at dietary habits in 52 countries, found people who ate a Western diet had a 35 percent greater risk of having a heart attack, compared to those who ate little or no fried foods and meat. Those who followed a "Prudent" diet had a 30 percent lower risk of heart attack, compared to those who eat little fruits and vegetables.

    The authors also looked at an "Oriental" diet, rich in tofu, soy and other sauces (酱类), and found it did not increase or decrease the risk of a heart attack.

    Previous studies have reached similar conclusions about the "Prudent" and Western diet in the United States and Europe, but did not include the Oriental pattern of eating. While some food of the Oriental diet may protect against heart trouble, the higher sodium (钠)content of sauces counter(抵消) that benefit.

    "This study indicates that the same relationships that are observed in Western countries exist in different regions of the world, "a professor of medicine at McMaster University said.

    Canadian researchers analyzed risk factors in food choices and the risk of heart attack in about 16, 000 people in 52 countries. Almost 6, 000 people had heart attacks, while the rest had no heart disease.

    The Earth is facing a climate crisis, but it's also getting greener and leafier. According to new research, the rise is largely due to China and India.

    A study by National Aeronautics and Space Administration (NASA), based on extensive satellite photographs and published in the journal Nature Sustainability, has revealed that the two countries with the world's biggest populations are also responsible for the largest increase in greenness.

    Since 2000, the planet's green leaf area has increased by 5 percent, or over 2 million square miles. That's an area equivalent to the sum total of the Amazon rainforests, NASA says. But researchers stressed that the new greenery does not neutralize deforestation and its negative impacts on ecosystems elsewhere.

    A third of the leaf increase is thanks to China and India, due to the implementation of major tree-planting projects alongside a vast increase in agriculture.

    Using the data from a NASA sensor, researchers discovered that China is the source of a quarter of the increase in green leaf area, despite possessing only 6.6 percent of the world's vegetated area (植被区). Forests account for 42 percent of that increase, while croplands make up a further 32 percent. China's increase in forest area is the result of forest preservation and expansion programs, NASA said, established to fight against the impacts of climate change, air pollution and soil erosion (水土流失). India has contributed a further 6.8 percent rise in green leaf area, with 82 percent from croplands and 4.4 percent from forests.

    Rama Nemani, a co-author of the study and a researcher at NASA's Ames Research Center, said in a statement, "When the greening of the Earth was first observed, we thought it was due to a warmer, wetter climate and fertilization from the added carbon dioxide in the atmosphere, leading to more leaf growth in northern forests, for instance." "Now, with the data that lets us understand the phenomenon at really small scales, we see that humans are also contributing," Nemani said. "This will help scientists make better predictions about the behavior of different Earth systems, which will help countries make better decisions about how and when to take action."

    Thomas Pugh, a professor at the University of Birmingham's School of Geography, Earth and Environmental Sciences, said the NASA report expands scientists' understanding of the causes behind global greening. But he also cautioned that a direct line cannot be drawn between an increase in global greening and a decrease in negative impacts of climate change.

    In ancient Egypt, a shopkeeper discovered that he could attract customers to his shop simply by making changes to its environment. Modern businesses have been following his lead, with more tactics(策略).

    One tactic involves where to display the goods. For example, stores place fruits and vegetables in the first section. They know that customers who buy the healthy food first will feel happy so that they will buy more junk food later in their trip. In department stores, the women's shoe section is generally next to the women's makeup section: while the shop assistant is going back to find the right size shoe, bored customers are likely to wander over and find some cosmetics they might want to try later.

    Besides, businesses seek to appeal to customers' senses. Stores notice that the smell of baked goods encourages shopping, so they make their own bread each morning and then fan the bread smell into the store throughout the day. Music sells goods, too. Researchers in Britain found that when French music was played, sales of French wines went up.

    When it comes to the selling of houses, businesses also use highly rewarding tactics. They find that customers make decisions in the first few seconds upon walking in the door, and turn it into a business opportunity. A California builder designed the structure of its houses smartly. When entering the house, the customer would see the Pacific Ocean through the windows, and then the pool through an open stairway leading to the lower level. The instant view of water on both levels helped sell these $10 million houses.

New research from the University of Portsmouth has shown a marked increase in shipping in the North East Atlantic. Scientists now warn that more monitoring is required to help protect sea life. 

Researchers at the University of Ponsmouth have discovered that rates (率)of shipping in the North East Atlantic area rose by 34 per cent in a five-year period. The research is the first detailed survey of shipping activity in the North East Atlantic. Researchers used data from over 530 million vessel(船)positions recorded by Automatic Identification System(AIS). They looked at the change in shipping between 2013 and 2017 across ten different vessel types. In total the study area covered 1.1 million km², including waters off Belgium, Denmark, France, Germany,Iceland, Ireland, The Netherlands, Norway, Portugal. Spain, and the UK. 

Lead author, James Robbins said:"This change is likely to put more pressure on the marine(海 洋的)environment, and may influence the protection of at-risk species. Renewed monitoring effort is needed to make sure that protective measures are enough to save species under threat in a changing environment. "

Some of the greatest shipping increases were found in areas close to the Spanish coast. The Espacio Marino de la Costa da Morte saw a rise of 413 percent in vessel activity. It is an area used to protect seabirds. 

Dr. Sarah Marley, Visiting Researcher at the University of Portsmouth, said:"Shipping is the most widespread human activity in our oceans, carrying a set of threats-from unnoticeable effects like underwater noise pollution to serious results when ships hit whales. "

Professor Alex Ford. from the University's Institute of Marine Sciences, said:"Given the well- documented effects that shipping can have on the marine environment, it is necessary that this situation continues to be monitored-particularly in areas used to protect vulnerable(脆弱的)species which may already be under pressure. "
