Christian Eijkman, a Dutch doctor, left the Netherlands for the island of Java. Many people on the island had a disease called beri-beri. He was going there to try and find a cure.

    At first, Eijkman thought some kind of germ (细菌) caused beri-beri. He raised some chickens. He didn't eat them, but made experiments on them. The local people were quite surprised at that. One day he noticed that his chickens became sick when they were fed the food most Javanese ate — refined white rice (精炼米). When he fed them with unrefined rice, also known as brown rice, they recovered. Eijkman realized that he had made an important discovery — that some things in food could prevent disease. These things were named vitamins. The Javanese were not getting enough vitamins because they had actually removed the part that contains vitamins. Later, other diseases were also found to be caused by the lack of vitamins in a person's food.

    Today many people know the importance of vitamins and they make sure they have enough vitamins from the food they eat. If they don't, they can also take vitamin pills.

    Every year there is a Spring Festival in China. Usually it is in January or February. It is the most important festival in China. So before it comes, everyone has to prepare things. They buy pork， beef, chicken, fruits and many other things. And they often make a special kind of food—“dumplings”. It means “come together”. On the day before the festival, parents buy new clothes for their children. Children also buy presents for their parents. On the Spring Festival Eve (除夕)，all the family members come back to their hometown. This is a happy moment. Some sing and dance, some play cards and others get the dinner ready. When they enjoy the meal, they give each other the best wishes for the coming year. They all have a good time.

    Throughout history, music spread through common experiences among people of different cultures. In today technologically advanced society, however, people spread music online, sometimes without an artist's permission. This can lead to many problems, and music companies are now cracking down on this practice. Sharing music online without permission is theft.

    Sharing music online prevents recording companies from making money from their efforts. They say that online file sharing has resulted in a huge drop in profits and sales over the past 10 years. People who find music for free online are not charged for CDs or every MP3 download. To truly understand the impact of music piracy (盗版)on creators, one must understand how many people are involved in the recording process. For the sale of each album, profits must be shared between all parties: musicians, sound engineers, music producers, managers advertisers, and the company selling the product. Many people believe sharing music only affects the recording artist, but the reality is that sharing hurts business for all companies involved. Therefore, the sharing of music files is just as damaging as stealing a CD from Target.

    There are many people who don't see the harm in sharing music files online and even think they have the right to do it. One online blogger states that he originally paid for an entire CD and that he “should be able to do with the material whatever he wants”. While he may have legally paid for the music, he does not have the right to provide it to the world at no cost. Most music is copyrighted(有版权的). No one can legally hand out free copies without permission, which means people like the blogger are thieves.

    Although we do not spread today's music the same way we did historically, there's no doubt that people around the world love to share music. However, internet piracy could prevent musicians from wanting to continue producing albums for fear of theft. Therefore, if people want to continue listening to their favorite artists, they need to buy their music so that artists will make enough profit to continue their music careers.

    To err is human. To blame the other guy is even more human.

    Common sense is not all that common.

    Why tell the truth when you can come up with a good excuse?

    These three popular misquotes(误用的引语) are meant to be jokes, and yet they tell us a lot about human nature. To err or to make mistakes, is indeed a part of being human, but it seems that most people don't want to accept the responsibility for the problem. Perhaps it is the natural thing to do. The original quote about human nature went like this, "To err is human, to forgive is divine(神圣的)."This saying mirrors an ideal: People should be forgiving of others' mistakes. Instead, we tend to do the opposite -- find someone else to pass the blame on to. However, taking responsibility for something that went wrong is a making of great maturity(成熟).

    Common sense is what we call clear thought. Having common sense means having a good general plan that will make things work well, and it also means staying with the plan. Common sense tells you that you take an umbrella out into a rainstorm, but you leave the umbrella home when you hear a weather forecast for sunshine. Common sense does not seem to be common for large organizations, because there are so many things going on that one person cannot be in charge of everything. People say that in a large company, "the right hand does not know what the left hand is doing."

    And what is wrong with a society that thinks that making up a good excuse is like creating a work of art? One of the common problems with making excuses is that people, especially young people, get the idea that it's okay not to be totally honest all the time. There is a corollary(推论) to that: If a good excuse is "good" even if it isn't honest, then where is the place of the truth?

Plus, carbon fiber can be seen everywhere, which makes thecar strong and lightweight. There're only 900 being built and you'llneed to coughup $517, 770 to buy one.

    ◆Aston Martin DBX

    The DBX is Aston Martin's maiden SUVproduct. It features a choice of two gas engines—a 4.0-liter V8 from Mercedes anda 5.2-liter V12 from its own. The price is predicted to be around $250, 000.

    ◆Audi E-tron

    Being an eco-friendly motoring, it is an all-electricSUV that makes up for its rather ordinary appearance with design, luxury and technology.At the front and back are electric motors which insure progress is rapid. In additionto plenty of storage space, the Audi E-tron provides side cameras instead of sidemirrors and air suspension that adapts to the terrain (地形). Hand over $74, 800 and it's yours.

    ◆Tesla Roadster

The top speed is 250 mph,which is also unheard of for most cars—let alone an all-electric one. Having advancedautonomous driving systems and a huge touchscreen for surfing the Internet, it won'tmake you regret for paying $200, 000.

Steven Stein likes to follow garbage trucks. His strange habit makes sense when you consider that he's an environmental scientist who studies how to reduce litter, including things that fall off garbage trucks as they drive down the road. What is even more interesting is that one of Stein's jobs is defending an industry behind the plastic shopping bags.

Americans use more than 100 billion thin film plastic bags every year. So many end up in tree branches or along highways that a growing number of cities do not allow them at checkouts(收银台). The bags are prohibited in some 90 cities in California, including Los Angeles. Eyeing these headwinds, plastic-bag makers are hiring scientists like Stein to make the case that their products are not as bad for the planet as most people assume.

Among the bag makers' argument: many cities with bans still allow shoppers to purchase paper bags, which are easily recycled but require more energy to produce and transport. And while plastic bags may be ugly to look at, they represent a small percentage of all garbage on the ground today.

The industry has also taken aim at the product that has appeared as its replacement: reusable shopping bags. The stronger a reusable bag is, the longer its life and the more plastic-bag use it cancels out. However, longer-lasting reusable bags often require more energy to make. One study found that a cotton bag must be used at least 131 times to be better for the planet than plastic.

Environmentalists don't dispute (质疑) these points. They hope paper bags will be banned someday too and want shoppers to use the same reusable bags for years.
