English is very important ,but now even i have studied english for many years  i can not speak it frequently . I will change it. I will use English not read or study it. I can use English read book,write diary or speak with somebody else. This is a net friend told me ,and i felt its a good method to improve my English Level. Yes ,it can .I believe I can do it , just like i  learning skating.
(ps: maybe there will be many mistakes ,but i think i could change is as long as i stick to the end.)

Start learning ,not only Cplusplus but also English!
