Chicago

Hi, everyone.  I am Wendy from China.  Since I was 13 years old, I began to learn English. But now I still can not speak it very well and express what I want to say correctly. I am very sad (frustrated)/(disappointed in myself).  Maybe I don't have a talent for learning a foreign language talent.  Reciting the words English pronunciation is a painful process for me.
Now I am in Chicago as an exchange student. I have been here for one week. I can't adapt to Chicago's life completely, which is very different with from China. But there are people who are very nice and friendly. I like them. And I also like the buildings in Chicago, which are very beautiful and magnificent; moreover, they have give people a sense of history.
I hope I will have a nice life in the next few months in Chicago. Of course, now my first task is improving my English.

Welcome to the windy city, Wendy!

Great job, Wendy! The third sentence you have two options, you can say (a) "I began learning English when I was 13 years old" or (b) "Since I was 13 years old, I have been learning English." (Or, it would be even better to say "I have been learning English since I was 13 years old."

Be very careful to make sure you always put a space ". " after periods (.) and commas (,) -- this will make your writing much easier to read, and make you look much more professional. 

Good luck!

Hi, everyone.

I am Wendy from China.  I started learning English at the age of 13 but I can not speak or express my self well. It is a painful process for me reciting some words. Currently, I am in Chicago as an exchange student.  It has been one week and I can not adapt to Chicago's life style. The people are nice and friendly.  Chicago is a beautiful and magnificent place but it seems more of a history aspect.  While I am here studying I hope to improve my English and enjoy my stay.
