✔ 最佳答案
Before answering your question, let me quote a part of a speech by President John F Kennedy delivered in 1963:
"And man can be as big as he wants. No problem of human destiny is beyond human beings."
Now back to your question, if you are determined to learn English (and stay away from Chinese, Chinatown, Chinese newspaper,publications, and all sorts!), then the answer is YES.
Techniques of learning a language: practice makes perfect, do not miss any opportunity that is available to you (like reading, talking to local people, even watch English TV program!)
Good luck, remember what can be imagined, can be achieved!
