I'm not sure why it has not been mentioned but there are a lot of grammatical errors in your 1st paragraph. I'm assuming you have already submitted it but if not here goes:
Ever since when I came to America when I was 10 years old, my computer and television became my best friends. Both of my parents started to work full time at the laundry cleaner right away, and I was left at my aunt’s house to face the unknown challenges at of the American elementary school. Being the first Asian student in the class has attracted many much attention, but my inabilityies to speak the English language and my lack of knowledge in American culture have made created a barrier for me to make new friends. However, by looking up English phrases in on the internet and watching children shows like “Arthur” in television, I was able to smash the barrier and connect with America. The media technology has expanded my intellectual horizon, and that is where my passion for the field of communication field has started.
