How What are some good ways to Study English? Well

We all know that English is very useful. Many people in the world speak English. So more and more people in China study it.

How What are some good ways to study English well? I think we must have a good way to study English. If you want to learn English well, listening, speaking, reading and writing are important. You should listen to tapes every day. You should often speak English often with your teachers and friends. You should read English every morning. And, You had also better keep a diary every day. In this way, you can study English well.

Overall very, very good.  Your punctuation is especially good compared to many notebook entires I've seen.  A few notes: 1) be careful where you put your adverbs of time - your sentence with "often" uses Chinese word order; 2) avoid starting a sentence with the word "and"; 3) "how to study English well" is really more of a statement than a question the way you worded it.  Again, you are using Chinese sentence structure with English words here.  "How do you study English well?" is a more natural translation.
