I find that the key is using more personal pronouns and articles. For instance, the phrase "how to speak english..." would normally be said "how do I speak english..." Chinese does not use personal pronouns and articles like English, so it is natural for Chinese learning English to drop them. When you say "how to speak english" it is obvious and logical to any English speaker that you are refering to yourself - however, it does not sound like naturally spoken English. There are a lot of small rules, also. For instance "mature" should be "maturely", since it modifies a verv ("speak"). "Natively" would be technically correct, but is not generally used. Another example would be the phrase "I need a taxi". The literal translation from the equivalent Chinese phrase would be "I need taxi", which drops the article "a". The problem is trying to apply the rules of your native language to the new language. I have exactly the same problem learning Chinese.

"how to speak english more like a native speaker and more naturally?" It is nearly impossible for people learning a new language to become like a native-speaker unless they drop everything, move to the country that speaks the new language, and live there for a few years. I found it really amusing when a gal from China told me that her English "pronounciation" is perfect. I chuckled because the word is "pronunciation." However, to improve your speaking, you need to begin with listening. So, surround yourself with English sounds everyday: listen to music, watch English TV shows and movies without subtitles, try to take notes when you are listening, and keep a notebook with what you notice. I will first tell you that when most Chinese students arrive to the U.S. that they cannot understand what Americans are saying. It's because Americans tend to speak garbled English. They blend sounds and reduce sounds all the time. When you are listening to English, play close attention to those blends and repeat after them. This will be a quicker way for you to understand how native English speakers talk everyday.

When you say you want to speak like native, the best way is to spend a lot of time with the native speakers. Without immersing into native environment, it is quite impossible to speak like native...
