I'm very lucky in learning English. During my study time, I never feel that English is boring, dull and difficult to learn. I have ever read the books that are written by the people who are good at English, they enlighten me very much. Basing on my own methods and experience, I sum up some learning methods and principles. If you can learn English according to these principles, you must learn English well.
During learning English, if you do according to principles, you can succeed; if you violate principles, you can not succeed. Certainly, whether success or failure, it depends on your efforts. If you do according to principles and make an effort, you will succeed.
Learn English: start from simplicity.
Use English: simple-good, simpler-better, simplest-best.
During my college days, our English teacher let us read a lot. Some students borrowed progenitors: the first page, more than 20 new words; the second page, still more than 20 new words...until the fifth page, they didn't know what the writer wanted to say. They felt reading was difficult and boring and they gained nothing. Reading progenitors became looking up dictionary、memorizing new words. So few people could insist and they gave up.
Much-good, more-better, most-best.
There is a saying "Repetition is the mother of skills". You can recall the process of learning any skill, for example, swimming or riding，you do the same action again and again. Any kind of skills, surely, including language skills, they all come from repetition.
As an English learner, you must imitate. Innovation roots in imitation，learning English and innovation are both based on imitation. Only you imitate others and grasp the soul of English, and then you can have your own language style.
Fifth, practice a lot in a short time.
If you want to learn English well, only thus do you have enough motive and interest, you can face study out. Do you still remember how you learn to ride bike, swim or drive your car? Do you learn these technical skills by practice a lot in a short time? Learning skills are the same as technical skills, they need practice a lot. Of course, learning English is not as easy as riding and swimming. Learn a kind of skills, practice a lot in a short time is an important principle.
"Interest is the best teacher", every body has his own interest. It is a key condition of learning English well that we must combine interest and English learning.
