When I came to Cincinnati as an au pair (家庭打工留学生), a lot of things there were different from what I knew. My host family lived in a huge house I could only describe as a "castle"．In Germany I had lived in a small apartment together with my mom. Soon I found out that the "castle" was actually rather small in our neighborhood.

    Everybody there was very friendly and polite. They greeted you when they were walking by at least 3 feet away from you. They must not have seen a German au pair before, for most people I met asked me all kinds of questions about Germany. I enjoyed answering their various strange questions. I made a lot of friends and I started to hang out with them.

    Of course, there were a number of new things, and it took me the whole year to find them all out. I never got homesick. Perhaps it was because I did not have too many negative experiences and felt loved and welcomed there.

    However, I had undergone some painful experience back in Germany. I was frustrated by the way people would run me over and not even say "Sorry." Taking up my studies at the TU-Dresden, I felt lonely. Everybody here seemed to be withdrawn(离群的) and I missed everything I had in Cincinnati. Germany was so "cold". I found it so much harder to make new friends. After six months I got a roommate and only two good friends. I also flew back to Cincinnati several times for long periods. I felt that without those visits I was not able to make it.

    Now I am over this German culture shock. It almost took me an entire year. I am still going back and forward between Dresden and Cincinnati four times a year.

    Culture shock is the psychological（心理的）shock of having to adapt to new environment and new cultures which may be completely different from your own. To understand culture shock helps to understand what culture is.

    Culture shock is caused by the feelings that result from losing all familiar signs and symbols of social intercourse（交往）. Those signs include the ways with which we are familiar in daily life: When to shake hands and what to say when we meet people? When and how to give tips? How to go shopping? When to accept and when to refuse invitations? These signs, which may be words, gestures, facial expressions, customs or normals are gained by all of us in the course of growing up and are as much a part of our culture as the language we speak.

    During the first few weeks when a person enters a strange culture, most people are attracted by the new. But this “cooks tour” type of mentality（心态）does not normally last if the foreign visitor remain abroad and has to seriously deal with real conditions of life. He may feel anxious and frustrated（受挫的） People react to the frustration in the same way. During the first period, they reject the environment which causes the discomfort. “The ways of the host country are bad because they make us feel bad,” they complain about the host country and its people. The following period is homesickness. The home environment suddenly becomes so important that all difficulties and problems are forgotten and only the good things back home are remembered.

    Experiencing culture shock can be very difficult. There is a risk of sickness or emotional problems. However, culture shock can be part of a positive learning experience. Be patient! It is a process of adaptation to new situations. If you do like this, you will be a much stronger person, and you will be a citizen of the world.

    In 1978, I was 18 and was working as a nurse in a small town about 270 km away from Sydney, Australia. I was looking forward to having five days off from duty. Unfortunately, the only one train a day back to my home in Sydney had already left. So I thought I'd hitch a ride(搭便车).

I waited by the side of the highway for three hours but no one stopped for me. Finally, a man walked over and introduced himself as Gordon. He said that although he couldn't give me a lift, I should come back to his house for lunch. He noticed me standing for hours in the November heat and thought I must be hungry. I was doubtful as a young girl but he assured(使…放心) me I was safe, and he also offered to help me find a lift home afterwards. When we arrived at his house, he made us sandwiches. After lunch, he helped me find a lift home.

    Twenty-five years later, in 2003, while I was driving to a nearby town one day, I saw an elderly man standing in the glaring heat, trying to hitch a ride. I thought it was another chance to repay someone for the favor I'd been given decades earlier. I pulled over and picked him up. I made him comfortable on the back seat and offered him some water.

    After a few moments of small talk, the man said to me, “You haven't changed a bit, even your red hair is still the same.”

    I couldn't remember where I'd met him. He then told me he was the man who had given me lunch and helped me find a lift all those years ago. It was Gordon.

    Many of us know about Russia's Lake Baikal from our textbooks, or by listening to Chinese singer Li Jian's hit song, Lie Baikal. But over the past decade, the world's deepest freshwater lake has been in the spotlight for an extreme sport.

    Each March since 2005, about 150 people from around the world sign up for the Baikal Ice Marathon. They come to explore the lake's breathtaking beauty and challenge themselves in unpredictable conditions. The 26-mile (41.84-kilometers) journey starts on the lake's eastern shore. In March, the ice is a meter thick and iron-hard. Runners cross this frozen surface, finishing on the western side of the lake.

    Known as the "blue eye of Siberia", Lake Baikal has exceptionally clear waters. This means its ice is almost perfectly transparent (透明的). "Seen from above, a runner on the ice looks as if he or she were jogging through space." The New York Times noted.

    The landscape might be beautiful, but it's also harsh. Strong winds blast (侵袭) across the lake and frostbite can occur within half an hour. Runners say the cold climate is what draws them. They want to test their limits.

    "When you are in such an environment, you don't have cars around you, and you don't have the noise around. I think these extreme races allow you to be alone with nature." Alicja Barahona, a 64-year-old runner from the US, told ABC news.

    The location offers some strange and unique characteristics for this marathon. The finishing line is visible from the start, but the endless white offers no progress markers. The race also ends with little fanfare (隆重的欢迎). Tourists crowding the ice are mostly addicted to snapping selfies (自拍) and just ignore the runners.

    For some runners, the absence of spectators makes the race more challenging, because it's lonely. They must fight with themselves. "You are alone on Baikal. It is your race. You are alone with yourself. All you need to do is to defeat yourself." Veronique Messina, a French runner, told the Telegraph.

An Art Class

When Kelly was twelve, she started taking classes at Miss Grace's School for Art. She didn't like it at first: the "novice artists"-the kids who hadn't really done art before-worked mostly with clay, and Kelly was a terrible sculptor. 

It wasn't until her third year that Kelly found something she was really good at-charcoal drawing （素描）. She loved watching the lines spread unevenly across the page as she moved the bits of charcoal back and forth over the paper. 

One day, Sophia. the best artist in her class, sat down and set up her easel （画架） next to Kelly. Kelly felt a sinking feeling in her stomach. She'd. actually found an art form that she enjoyed-and was good at--and now Sophia was going to outshine her again? Kelly fought back tears when Miss Grace entered the room. 

"Hello class, Miss Grace said. "We'll continue to work on the project today. What masterpiece would Sophia have come up with?

Kelly looked at Sophia's easel and she couldn't believe it--it was a mess! For a brief moment, Kelly couldn't actually believe her drawing was better than Sophia's. 

But then she looked at Sophia, who was watching Kelly with an anxious expression. "I…. I couldn't decide what to do, " Sophia said. "And you're so good. Sometimes I feel like my stuff is just so bad in comparison. 

Kelly looked to see if Sophia was joking, but she seemed completely serious. Now Kelly was shocked. "I'm not talented ... Miss Grace seldom praises me. You're the best one in our class!"

Sophia raised her eyebrows. "I might be a really good copier of the stuff, but I have no idea what to do when it comes to making up my own images. You are so great at making new things out of the old stuff. I've loved your works. "

"I've loved yours, too, Kelly said. 

"Well, definitely not this one, " Sophia said. 

Kelly smiled. "Maybe not right now. But if you move these lines up. . . "she said, pointing her finger on Sophia's paper. 

Sophia was quiet for a moment. "That's a great idea!" she said finally. 

Kelly smiled and turned back to her drawing, looking every so often at Sophia's work to see that she was taking her advice, down to the last line.
