     Each year, millions of people go abroad to work, study, or travel. It's a great way to find out what life is

like in another part of the world! You're probably hoping to make new friends and learn about the culture in

your host country everything from attitudes and beliefs to social customs and popular foods. But constantly

having to deal with new situations can be frustrating (挫折), even stressful.

     Homesickness, stress, fear, and confusion are all symptoms of "culture shock". At first, you may feel like

getting on the plane and heading home. It's OK to have those feelings,but the following are some tips to help

you handle the challenges that you will face.

     Don't expect to be perfect. You may feel frustrated that you have culture shock, especially since you

probably spent so much time preparing for your trip. No matter how much information you read, or how

well you speak the host language, it is natural to feel over-whelmed sometimes. If you give yourself some

time, things will gradually get easier.

     Have an open mind. While it's certainly OK to feel frustration or confusion in your new surroundings,

try not to form an opinion about the new culture too soon. Don't think of the host as better or worse, just

different-you'll be more willing to try new things.

     Participate. This is obvious, but everybody needs to be reminded. Just watching life go on around you

isn't good enough. You really need to try things for yourself. Don't worry about making a mistake; people

in your host country will generally be very understanding and willing to help if you have question. Your

study abroad experience is fl unique and special time in your life,one that you'll never forget. If you follow

our suggestions, you'll be able to handle it well, and have a wonderful time. Good luck!
