A polyglot is a person who uses multiple languages.

Here is one of polyglots I know ,Alexander Arguelles .He claimed he can speak 50 languages.

I learnt a useful technique,shadowing,from him,just like he learnt Chinese as below

So ,you must keep in your mind,you also can speak and read english freely ,if you want.

Shadowing is perfect,but maybe it doesn't fit you.I recommend you build your pronounciation first,and follow some instructions from "英语：零章"
