Hi Sharon，
This is Li Hua．I learned from your post that you want to improve your Mandarin．I am quite interested in it．I think I'm fit for it．（表達(dá)給她提供幫助的意愿）As a student，I have been learning Mandarin for many yea rs．In addition，I am Chinese，which means Mandarin is a must for me to communicate with others in my daily life．So I'm quite confident thatI can help you learn Mandarin．（說(shuō)明自己能勝任輔導(dǎo)的理由）Learning Mandarin takes time，so if you want to learn it well，you should spend much time practicing Mandarin everyday．As the saying goes，practice makes perfect．Besides，you can also read some books in Chinese、see some Chinese films and listen to some Chinese radio programmes．Speaking and listening are very important for a language learning，by which you are sure to make great progress．（講好普通話的兩點(diǎn)建議）
In your post，you say you can teach English as a reward．It is just what I want．I'm eager to improve my English．So，if you allow me to help you learn Mandarin，you can also help me improve my English．We can contact each other by video chat every night for half an hour in English and half an hour in Chinese，so that we can improve our oral speaking．Hope for you early reply!（提出自己學(xué)習(xí)英語(yǔ)的具體需求）．
Sincerely，
Li Hua．
