your parlance“我找朋友跟他一起练习说中文”can lead to some different meaning. One is you are looking for a friend to practise chinese with somebody(he is a man),maybe he is your friend or families or some one the reader unknow. Another is you are looking for a friend to practise chinese together with you. I took the second meaning when my first view of you parlance, and I feel very strange! I know that you have translated the English sentence into chinese! The right parlance is "我想找个朋友和我一起练习中文",This is what you really mean! right? I 'm saying so much, just in order to make friends with you,and hope we can help each other! if you want,see my data and contact me!
