    Well-known for historic architecture and chocolates, Lviv, Ukraine's official capital of culture, looks, smells, and tastes like the best of Europe. Indeed, its western flavor has earned it the title "Little Paris of Ukraine".

    For centuries Lviv, located 50 kilometers from the Poland-Ukraine border, was an important stopping point on the main trade routes between the east and west. During the Renaissance, the city could afford Italy's finest architects because every merchant passing through was forced to stay and sell their goods for at least two weeks. "It was a very smart move to collect money from them," said Yaroslav Hrytsak, a local historian, adding, "It kept the wealth in the city, and that wealth has been transformed into architectural richness."

    Many historic buildings remain but Lviv's prosperity didn't survive its bloody history. Over the centuries, the city fell under the rule of Poland, Austria, Austria-Hungary, Russia and the Nazi Germany. In addition, both Sweden and Turkey tried unsuccessfully to conquer the city. Then for almost half a century Lviv was ruled by the Soviet Union (苏联). With that, the city was condemned to relative obscurity(无闻). But recently things have started to change. Lviv experienced a sudden 40% increase in tourism in early2010, which was the highest rate in Europe. Just last month, its gates opened even wider, when Lviv became a host city for the Euro 2012 football championships.

    So how has this happened? With the Soviet collapse, some saw new opportunities for reviving Lviv's former wealth and fame.

    Limelight networks is a US-founded company. It's one of many digital tech firms to have opened offices in Lviv over the past few years. "It had good growth and experience in the US, however, the company needs more talent to do the new cool projects and products for our customers. This is why we're here in Ukraine." said CEO of Limelight networks.

    Lviv's unexpected abundance of I.T. talent is in fact a legacy(遗产) of the former Soviet Union. To help the military, many Soviet universities focused on turning out world-class engineers and Lviv's university is still producing them. Now, the city is home to 23 higher education institutions. It's clear that the city of Lviv does not intend to remain a hidden jewel for much longer.

    Last week I was riding my special motorbike and then stopped at a convenience store.As I was getting my wheelchair off the back,a man watched me from his car and I noticed a wheelchair in his back seat.We spoke for a moment and I asked him about the wheelchair.He answered that it was for his daughter.“Well,do you think she would like to go for a ride on my motorbike with me?”I asked.He seemed shocked that a total stranger would ask him this.He thought about it for a second and said,“OK,as long as I can follow you.”

    He introduced me to Amy and he sat her on my back seat.Her father followed me for a few miles and she talked non-stop about what she wanted for Christmas.

    As we came back to the convenience store,she said,“This ride is the best Christmas present I could ever receive. I have been in a wheelchair my whole life and didn't know I could do this.”I told her about some of the other things I do (ski,travel the world by myself,etc.).As her father was taking her off my bike,she turned to him and said,“Oh Daddy,I'm going to be OK.Mr.Bryant does all kinds of things,and I win too.” Her father turned away as a tear of joy rolled down his cheek.He hugged me and said,“I was sitting here praying for a gift for Amy that would encourage her.She often felt that her life was dull compared to other children.God answered my prayer just now.Now I pray that God will bless you for your gift to Amy today.” I believed what he said.Being kind and thoughtful to others,we can be an answer to prayer.

    Education is not a bystanders sport. Numerous researchers have shown that when students participate in classroom discussion they hold more positive attitudes toward school, and that positive attitudes promote learning. It is no coincidence that girls are more passive in the classroom discussion and score lower than boys on SATs.

    We found that at all grade levels in all communities and in all subject areas boys controlled classroom communication. They participated in more interactions than girls did, and their participation became greater as the year went on.

    Our research contradicted the traditional assumption that girls control classroom communication in reading while boys in math. We found that whether the subject was language arts and English or math and science, boys got more than their fair share of teacher attention. That teachers talk more to male students is simply because boys are more aggressive in grabbing their attention by calling out answers to the teachers' questions first. While girls sit patiently with their hands raised or keep silent. Psychologist Lisa Serbin and K.Daniel O'Leary, then at the state university of New York at stony brook studied classroom interaction at preschool level and found that teachers gave boys more attention, praised them more often and were at least twice as likely to have extended conversations with them.

    Years of experience have shown that the best way to learn something is to do it yourself. It is also important to give students specific and direct feedback about the quality of their work and answers. Teachers behave differently depending on whether boys or girls are active to provide answers during discussions. During classroom discussion, teachers in our study reacted to boys answers with powerful, precise and effective responses, while they often gave girls mild and unclear reactions because of their silence. Too often, girls remain in the dark about the quality of their answers. Active students receiving precise feedback are more likely to achieve academically. And they are more likely to be boys.

    This kind of communication game is played at work, as well as at school. As reported in numerous studies, it goes like this.

    Men speak more often and frequently interrupt women.

    Listeners recall more from male speakers than from female speakers, even when both use a similar speaking style and cover the same content.

    Women participate less actively in conversation. They do more smiling and gazing, and they are more often the passive by standers in professional and social conversations among peers.

    Women often their own statements into unsure comments. This is accomplished by using qualifiers and by adding tag question. These uncertain patterns weaken impact and signal a lack of power and influence.

    Only when girls are active and treated equally in the classroom will they be more likely to achieve equality in the workplace.

    When you think back to the blackboard from your school days, what color is it? Chances are that it's green. So what's up with the name? Originally, blackboards were really black. Before wall-sized blackboards existed, late 18th-century students used their own mini boards made of slate (石板) or painted wood, according to Concordia University, Those first boards were, in fact, black, and they paved the way for the larger ones.

    In 1800 when a Scottish headmaster named James Pillans wanted his students to draw maps, the students couldn't draw the maps their teacher wanted on their tiny boards, so Pillans put several slates together to create a large board. Problem solved! From there, the idea spread quickly as teachers could finally show a concept to the whole class at one time. By 1815, the massive writing spaces were common enough to earn their own name: blackboard.

    The color change came in the 1960s when companies sold, steel plates, coated with green enamel (漆) instead of the traditional dark slate. The new material was lighter and less fragile than the first blackboards, so they were cheaper to ship and more likely to survive the journey. Teachers weren't complaining either. After all, the new "greenboards" made the chalk powder easier to erase. Plus, the enamel left less of a glare and the color was nicer to look at. At that point, people started using the word "chalkboard "as a more accurate descriptor, but "blackboard" still stuck around.

    You are a member in a full-time school called "life". Each day here you will have the opportunity to learn lessons. You may like the lessons or hate them, but you have designed them as part of your curriculum.

    Why are you here? What is your purpose? Humans have sought to discover the meaning of life for a very long time. What we and our ancestors have to overlook is that there is no one answer. The meaning of life is different for every individual.

    Each person has his own purpose and distinct path, unique and separate from anyone else's. As you are traveling your life path, you will be presented with numerous lessons you will need to learn in order to achieve that purpose. The lessons you are presented with are specific to you; learning these lessons is the key to discovering and achieving the meaning of your own life.

    As you are traveling through your lifetime, you may meet challenging lessons that others don't have to face, while others spend years struggling with challenges that you don't need to deal with. You may never know why you are blessed with a wonderful marriage, while your friends suffer painful divorces, just as you cannot be sure why you struggle financially while your peers enjoy abundance. The only thing you can count on is that you will be presented with all the lessons that you specifically need to learn.

    The challenge, therefore, is to arrange yourself with your own unique path by learning individual lessons. This is one of the most difficult challenges you will face in your lifetime, as sometimes your path will be different from others. But don't compare your path with that of people around you and focus on the differences between their lessons and yours. You need to remember that you will only face lessons that you can learn and are specific to your own growth.

    Our sense of fairness is the expectation of equality. Life is not, in fact, fair, and you may indeed have a more difficult life path than others around you, deserved or not. Everyone's circumstances are unique, and everyone needs to handle his or her own circumstances differently.
