we have been learning english for a long time,and there's always a question out there,"how to learn english well",next,i'll tell you my suggestion.
First,listening skill is quite important,i think we should listen it everyday; secondly, we can learn to speak to our friends in english,never be afraid of making mistakes; thirdly,read some english articles,and soon you'll have some feel called language sense;finally,we can write an english composition each weekend.After all this ,i believe your english will be quite good!
Do it,from now on.
