First notebook entry: Introducing myself

wo xuexi han yu, yin wei you yi tian wo qu zhong guo dang lu shi :)

wo3 xue2 xi2 han4 yu3, yin1 wei4 wo2 xiang3 (The original tone of 我wo3 is the 3rd tone, but since there is another 3rd tone 想xiang3 after the 我wo3, so in this sentence 我wo3 should be pronounced wo2.) qu4 zhong1 guo2 dang1 lao3 shi1.

我学习汉语，因为我想去中国当老师。

Setp by setp, I think you can do well. Keep working hard on it, I believe you can achieve. Hope it helps. :)

我学习汉语，因为将来我想去中国当老师。

Кстати, ты хочешь стать учителем или юристом? Если учитель, то "lao shi", а если юрист, то "lv shi". :)
