The production of coffee beans is a huge, profitable business, but, unfortunately, full-sun production is taking over the industry and bringing about a lot of damage. The change in how coffee is grown from shade-grown production to full-sun production endangers the very existence of, certain animals and birds, and even disturbs the world's ecological balance.

    On a local level, the damage of the forest required by full-sun fields affects the area's birds and animals. The shade of the forest trees provides a home for birds and other special(物种) that depend on the trees' flowers and fruits. Full-sun coffee growers destroy this forest home. As a result, many special are quickly dying out.

    On a more global level, the destruction of the rainforest for full-sun coffee fields also threatens(威胁)human life. Medical research often makes use of the forests' plant and animal life, and the destruction of such species could prevent researchers from finding cures for certain diseases. In addition, new coffee-growing techniques are poisoning the water locally, and eventually the world's groundwater.

    Both locally and globally, the continued spread of full-sun coffee plantations (种植园)could mean the destruction of the rainforest ecology. The loss of shade trees is already causing a slight change in the world's climate, and studies show that loss of oxygen-giving trees also leads to air pollution and global warming. Moreover, the new growing techniques are contributing to acidic(酸性的) soil conditions.

    It is obvious that the way much coffee is grown affects many aspects many aspects of life, from the local environment to the global ecology. But consumers do have a choice. They can purchase shade-grown coffee whenever possible, although at a higher cost. The future health of the planet and mankind is surely worth more than an inexpensive cup of coffee.

    The human body is designed to move. But modern lifestyles and office jobs rarely give us the chance to move around. As we know, we're sitting while we're eating; we sit in the car and we sit while we watch TV. And many of us sit for many hours at work.

    New research shows that sitting less than three hours a day might extend your life by two years. Peter Katzmarzyk, a scientist at the University of Louisiana in the southern United States, says that sitting is ubiquitous in our lives, meaning it is something we do all the time, everywhere.

    However, Mr. Katzmarzyk says that does not mean you can sit for the rest of your waking hours. He also says you may exercise often, "We can't throw away physical activity. It's extremely important. We have 60 years of research showing us that."

    Mr. Katzmarzyk and his colleagues are part of a new generation of researchers studying how sitting all day affects length of life. "Studies that have assessed the relationship between sitting and mortality (死亡率) or television viewing and mortality are very rare. There's only been a few of them, actually five or six now, in the last four or five years." They found that cutting television time to less than two hours a day could add one point four years to life.

    Luckily, change is already coming to some offices, especially in the design of desks. A "standing desk" lets people stand while they work. Another new design is called the "treadmill desk." A treadmill is an exercise machine that lets you walk in one place. Even some U.S. schools are beginning to experiment with desks that are part bicycle to keep children moving. That's one of the strategies that many companies are using now.

    Mr. Katzmarzyk also says studying this problem has inspired his team to make a few changes in their own lives.

    Many people trying to sell homes find that an increase in home prices has turned the market in their favor. But sellers can still get the short end of the deal if they aren't careful. Here are a few tips for you:

    Don't test your luck. Of course you think anyone who moves into your lovely home should be willing to pay top dollars, especially if you've recently invested in some improvements. But listing a home at a price that's too high above the market price could turn away some buyers.

    Buyers noticing that the home which still hasn't been sold may begin to assume there's something wrong with the house and use that as a reasonable excuse for offering a lower price. And if a home hasn't received any offers after two weeks, it might be time to reset the price.

    A price that's too low can bring about an undesired outcome. Listing your home at or slightly below the market price can have the effect of drawing in a large group of buyers and increase the chances that a home will receive multiple offers. But setting the price too low comes with several risks. One possibility is that buyers will get skeptical of the home that is listed for $15,000 to $20,000 less than similar homes in the area, especially if it's not properly marketed. Once again, people might assume there is something wrong with the home and may not bother to look at it.

    Spy on the competition. Going to other people's open houses can give you a better sense of how your home compares with others on the market. Check out the decoration in their kitchens, the size of their backyards and use the information to figure out where your home should fit in the range of the price. But don't set your pricing just on what you see elsewhere.

    Learning English as the second language for non­native English speakers is not an easy task. It needs to spend a considerable time before you could speak or write the English language. There are only two ways to learn the English language or any other language you prefer.

The first one needs a lot of money because of the requirements needed. If you notice, a person migrated(移民) to another country and stayed there for a couple of years and then going back to his home non­native speaking country, the person became so familiar in speaking English. This is the most effective way of learning to speak and write a language unfamiliar to you.

    The learner learns the language because he/she is forced to do so because there is no other language being used. Not to mention that the learner should adapt to the environment. It is all started from listening. This is the process how language is acquired if you will stay long in a foreign country.

    The second one is the traditional way. You go to school or learning center specialized in teaching English as the second language. Obviously, this is cheaper than the first, but it needs a considerable time before you will learn to familiarize the language. Today, there are different language centers offering their services for people to learn the language in your own country. They brought all the materials needed because, compared to the first one, they're affordable and reasonable.

    Nowadays, learning English as the second language is one of the global trends. Since the English language is used in most of the business transactions, you should be on it too. Otherwise you will not go along with the future trends that will arise.

The Mona Lisa is one of the most famous paintings in the world. Painted by Leonardo da Vinci in the early 16th century, it has captivated audiences for centuries with its mysterious smile and masterful technique. 

The painting is housed in the Louvre Museum in Paris, France, and attracts millions of visitors each year. However, the Mona Lisa's history is not without controversy. There have been numerous attempts to steal or deface the painting, and its conservation has been a subject of great concern.

Leonardo da Vinci's use of sfumato, a technique that blends colors and tones seamlessly, gives the painting a soft and hazy appearance. The sitter's expression, which seems to change depending on the viewer's angle and mood, adds to the intrigue of the work.
