How can you improve your spoken english

These advices are from BBC China and the following is what I summarized from them.

We can focus on three topics about this title - pronunciation,accents and fluency vs accuracy.

First,It's about pronunciation.
a. imitate and practice
b. don't shy,you should be thick-skinned and forget you are Chinese
c. remember the stress(重音)

Secondly,it's about accents.
a. No perfect accent
There is no such thing as a standard accent in English.
How many percent of the population in UK speak with RP(Recept English-标准英语)? The answer is 2%.
b. Intelligibility is the key
You don't have to sound like a native speaker of English to achieve your goal in life.
c. Have a slight accent can be attractive
Finally,It's time for Fluency vs Accuracy.
a. Not focus too much on accuracy
b. Not too polite
c. Be confident
