How to learn German? I've been learning German for half a year with a teacher, three years ago.After that I learned all by myself,but stopped for two years... I can pronounce German,but the German grammar is too hard for me.I have a book <Neues Konzept für Deutsch> and sometimes I use the software “Rosetta Stone” to learn German. In my opinion,I must learn the single German words first,then try to every sentence. The most important,I must adhere to study. It's always easy for me to give up :( So, what do you think? Thank you 谢谢 :)

So the summer holiday I stay at home and not go to work. Well,I just graduated from my college in June. And I haven't worked yet. I always feel confused. What should I do? What can I do? When I was a child,I wanted to study animals and to be a doctor for animals. I love animals all the time. And before entering the college,I wanted to learn German. But my parents didn't agree.That's terrible,I am always controlled by them. Even my college is in my city. I have few opportunities to travel out. I just like in the greenhouse that built by my parents. My heart is not strong. I want go out,but I'm afraid,the weakness of my character. I think I lost my confidence. :(

Hallo. Guten Tag. Heute ist Donnerstag. Es ist regnerisch heute. Ich bleibe zu Hause. Ich mag die Bundesliga Fussball Spiele. Ich liebe deutschen Fussball seit der WM 2006. Ich lernte Deutsch in 2007. Aber Ich kann jetzt nicht mehr erinnern. Also muss Ich ernst jetzt lernen. Ich studieren Elektronische und Informationstechnik als Studienfach. Ich absolvierte im Juni 2011. Vielen Danke. Lieben Gruß. merrycube :)
