You could try finding a tutor that you feel comfortable with. Someone who helps you to have more fun learning the language. Someone who can help you with your pronunciation and teaches new idioms. Lessons which help you to learn and practice situational vocabulary might be helpful. As long as you continue to practice what you learn outside of class, then you should have no problem achieving your goals. Send me a message if you have more questions as this is the kind of service I provide for my students.

thx

Hello, my first suggestion would be that you study every grammar topic on the paper first then practice the same grammar until you could speak it really fast. This is a good way to make sure that you can speak every kind of sentences fast in another language. Also, please always read , watch and listen to real English from native speakers and notice how they go different in their speech from the grammar on paper. When it comes to vocabulary, please make sure that when you learn a new word, you encounter them many times. Reading is the best for that. Lastly, make sure that your pronunciation is good enough not to hold you back from speaking. Hope this helps!

Please try to punctuate correctly - you need a space after every .,?! Teaching punctuation seems to be a standard failure with Chinese teachers. Slang is uncountable, so there is no such word as slangs. Try slang terms. But then, slang varies a lot from age group to age group, and country to country, so I would not worry about that so much.
