My weak parts

Well, althought I've already gone to upper-intermediate class, there're still lots of words I don't know, lots of things I can't tell, and lots of sentences I don't understand!

Yestarday in school we talked about sports, I rarely could say anything in class, I even couldn't say these varied sports' names. All the sport languages, like rules, peoples' positions, fields, spesific terms, their clothes and equipments.... a lot of things I don't know! I used to play basketball when I was a junior hight school student, then I've never played any kinds of sports until now. Most of the terms about basketball I've already forgotten, and the rest terms I only know in mandarin. Even other sports! Therefore, I couldn't say anything durign my class. Although Victor gave me chance to say something, I could only say "I don't know the game." That's really really bad!

What's more is about worldwide knowledges. I don't know famous peoples' names, no matter ancient famous people or modern, I just don't know them! I also don't know significant events in neither eastern nor western history. Of course I studied it in my school before, but I just couldn't remember it. So when we talked about "Neil Armstrong", I only knew his name and he is the first man steped on the moon. When we talked about "Nelson Mandela", I totally didn't know who he is! "Magaret Thatcher" "......I don't know who she is!" etc...... That's too bad!!!

Also Taiwan's food, British laws, so many things I want to chat with my classmates.... Ahhh....
I know it takes time, I'll be more patient to learn and learn harder! Because I have too many weak parts!!
