In the frozen continent of Antarctica scientists fear an alien invasion — not from outer space, but carried in people's pockets and bags.

    Seeds and plants accidentally brought to Antarctica by tourists and scientists may introduce alien plant species which could threaten the survival of native plants in the finely balanced ecosystem.

    “The people that were carrying the most had lots and lots of seeds. They really were real threats,” said Dana Bergstrom, from the Australian Antarctic Division.

    “When we take things in through hitchhiking（搭车旅行） then we get species which are competitive. The plants and animals there are not necessarily competitive, so we'd start losing various precious biodiversity（生物多样性） on the (Antarctic) continent”, Bergstrom told Reuters.

    Amongst the alien species discovered were the Iceland Poppy, and Annual Winter Grass — all from cold climates and capable of growing in Antarctica.

    The Antarctic Peninsula, where most tourists travel, is now considered a “hot spot” on the frozen continent and the warmer the climate, the easier for seeds to grow. “The peninsula(半岛) is warming at some of the greatest rates on the planet,” said Bergstrom.

    The study, the first continent-wide assessment of invasive species in Antarctica, surveyed about 1,000 passengers during 2007-2008, the first year of the International Polar Year, an international effort to research the polar areas.

    Bergstrom said the one alien seed that had gained a foothold is Annual Winter Grass. It is a strong weed in the sub-Antarctic and is on the Antarctic island of King George. It has also made its way to the tail part of the Antarctic continent.

    One of the most practical parts of my college education (and my entire education)was my student teaching. For six month, I gradually took over until I was completely teaching the class. It wasn't quite the same as a real teaching job. However, it was definitely a good way to get some real world experience. School should prepare students for the job market. Therefore, are our kids receiving enough practical education so they can be successful in the real world?

When teaching kids, it's important to be able to have a purpose for everything we teach. As parents and teachers, we should ask ourselves: what can this be used for when kids enter the job market? I can think about a college class I took where we had to analyze various movies. I honestly can't think of how analyzing "Rambo" benefited me. Perhaps, I would have been better off taking an auto shop class or a carpentry class. After all, I can't change a tire and I'm completely incapable when it comes to using power tools. The Guardian points out that the current generation is one of the most educated but lacks the skills to mend a hole in a shirt or put up a shelf. We have become a society that hires someone else to do these basic tasks. So how can we fix this?

    Perhaps, learning how to think is not enough. Rather than focusing on standardized tests so much, schools need to give students more practical application. Cooking is actually helpful when teaching children about fractions, measuring and multiplication. Students can learn how to double a recipe and see the relationship between 1/4 and 1/3 cup. As kids get into the upper grades, money management should be a focus. Making a budget and learning about interest rates are good ideas. I used to give my students real restaurant menus and a budged. They had to come up with what they could buy, including the tip with a set amount of money. In college, rather than only focus on the craft of writing, I wish I would have learned more about marketing and publishing my writing. Finally, internships in both high school and college should be required.

It appears that some high schools are doing a better job of preparing students for the real world. For instance, according to NBC News, in Michigan, "the Utica Center for Science and Industry uses technology to prepare students for automotive and military industry jobs." The program aims to combine students' skills with employers' needs. Students take optional courses in areas such as "multimedia, engineering or mechatronics" and also take part in activities where there isn't one right answer. For me, giving kids the opportunity to create is the key point. So far, the program is showing success.

According to a Gallup poll, fifty-seven percent of American workers say "the type of work they do generally" does not require "a bachelor's or a more advanced degree." Therefore, if a college degree isn't helping the majority of Americans at their job, then what is required? Many jobs require a skill. Electricians and contractors have specific skill that allow them to complete their jobs. Whether students go to four-year school or not, I think it's important for everyone to have a skill. After all, a Forbes article states that half of college graduates are working at jobs that don't require a degree. Clearly, being smart and qualified isn't always enough to make it in the real world.

    I'm going to encourage my kids to go to college and earn a degree. I'm also going to encourage them to think outside of the box and give them a practical education too. After all, you never know where life will take you.

    Birthdays often involve surprises.But this year's surprise on the birthday of the great British playwright William Shakespeare is surely one of the most dramatic.

    On April 22,one day before his 441st birthday anniversary,experts discovered that one of the most recognizable portraits（画像）of William Shakespeare is a fake.This means that we no longer have a good idea of what Shakespeare looked like."It's very possible that many pictures of Shakespeare might be unreliable because many of them are copies of this one,"said an expert from Britain's National Portrait Gallery.

    The discovery comes after four months of testing using modern chemistry technology.The experts from the gallery say the image—commonly known as the "Flower portrait"—was actually painted in the 1800s,about two centuries after Shakespeare's death.The art experts who work at the gallery say they also used modern chemistry technology to check the paint on the picture.These checks found traces of paint dating from about 1814.Shakespeare died in 1616,and the date that appears on the portrait is 1609.

    “We now think the portrait dates back to around 1818 to 1840.This was when there was a renewed interest in Shakespeare's plays,”Tarnya Cooper,the gallery's curator（馆长）,told the Associated President.

    The fake picture has often been used as a cover for collections of his plays.It is called the Flower portrait because one of its owners,Desmond Flower,gave it to the Royal Shakespeare Company.

    “There have always been questions about the painting,”said David Howells,curator for the Royal Shakespeare Company.“Now we know the truth,we can put the image in its proper place in the history of Shakespearean portraiture.”

    Two other images of Shakespeare,are also being studied as part of the investigation and the results will come out later this month.

    While famous foreign architects are invited to lead the designs of landmark buildings in China such as the new CCTV tower and the National Center for the Performing Arts, many excellent Chinese architects are making great efforts to take the center stage.

    Their efforts have been proven fruitful. Wang Shu, a 49-year-old Chinese architect, won the 2012 Pritzker Architecture Prize — which is often referred to as the Nobel Prize in architecture — on February 28. He is the first Chinese citizen to win this award.

    Wang serves as head of the Architecture Department at the China Academy of Art (CAA). His office is located at the Xiangshan campus(校园) of the university in Hangzhou, Zhejiang Province. Many buildings on the campus are his original creations.

    The style of the campus is quite different from that of most Chinese universities. Many visitors were amazed by the complex architectural space and abundant building types. The curves(曲线) of the buildings perfectly match the rise and fall of hills, forming a unique view.

    Wang collected more than 7 million abandoned bricks of different ages. He asked the workers to use traditional techniques to make the bricks into walls, roofs and corridors. This creation attracted a lot of attention thanks to its mixture of modern and traditional Chinese elements(元素).

    Wang's works show a deep understanding of modern architecture and a good knowledge of traditions. Through such a balance, he had created a new type of Chinese architecture, said Tadao Ando, the winner of the 1995 Pritzker Prize.

    Wang believes traditions should not be sealed in glass boxes at museums. "That is only evidence that traditions once existed," he said.

"Many Chinese people have a misunderstanding of traditions. They think tradition means old things from the past. In fact, tradition also refers to the things that have been developing and that are still being created," he said.

    "Today, many Chinese people are learning Western styles and theories rather than focusing on Chinese traditions. Many people tend to talk about traditions without knowing what they really are, "said Wang.

    The study of traditions should be combined with practice. Otherwise, the recreation of traditions would be artificial and empty, he said.

    Going green seems to be a fad (时尚) for a lot of people these days. Whether that is good or bad, we can't really say, but for the two of us, going green is not a fad but a lifestyle.

    On April 22, 2011, we decided to go green every single day for an entire year. This meant doing 365 different green things, and it also meant challenging ourselves to go green beyond the easy things. Rather than recycle and reduce our energy, we had to think of 365 different green things to do and this was no easy task.

    With the idea of going green every single day for a year, Our Green Year started. My wife and I decided to educate people about how they could go green in their lives and hoped we could show people all the green things that could be done to help the environment. We wanted to push the message that every little bit helps.

    Over the course of Our Green Year, we completely changed our lifestyles. We now shop at organic(有机的) stores. We consume less meat, choosing green food. We have greatly reduced our buying we don't need. We have given away half of what we owned through websites. Our home is kept clean by vinegar and lemon juice, with no chemical cleaners. We make our own butter, enjoying the smell of home-made fresh bread. In our home office anyone caught doing something ungreen might be punished.

    Our minds have been changed by Our Green Year. We are grateful for the chance to have been able to go green and educate others. We believe that we do have the power to change things and help our planet.
