Native English speaker tutor vs. Chinese tutor
What's the advantage to learn from a foreigner?
Learning from a native English speaker tutor has more advantage for intermediate or advanced level students than for total beginners. If you are a very slow learner, you may consider a local Hong Kong English teacher if you prefer cheaper tuition fee.
If the teacher a Westerner and cannot speak Chinese, you will not have temptation to switch from English to Chinese when you feel difficult to express yourself or you're too tired.
If you are beginner, a Chinese tutor can explain the meaning of words and the grammar to you. So it's good for easier understanding.
In my private English classes I usually teach on 1-1 basis so I can focus on your specific needs, speed and learning habits. However, you will be exposed to English all the time and you need to focus.
How to speak and understand native English speakers better
Spend a lot of time listening to people who speak English. Watch American movies and British films. Listen to English songs or even sing together with the singer. Karaoke is a good way to improve your English. Listen to BBC radio programs.
Speak not only to native English speakers but also to people from all over the world. Get used to their different accents.
Remember, there is no one ideal English accent or English version. Even within a country people speak English differently.
Spending more time to learn and practice English in only one way to improve your English faster during a given time period. There are some other ways, too, that almost nobody thinks of. And this is often the starting discussion topic on the first lesson with my students. You can learn, too, how to accelerate your English learning efficiency.
The speed to move from a certain level to another one can be several times faster for a relatively successful student compared to a relatively slow one. And I am not talking about extremely smart and mentally challenged students. I will teach you how to improve your English faster when you come to learn.
