Improve My English Plan

For all aspects of English, including listening, speaking, reading, writing.

I usually reading the paper in every day so my reading is not poor but I need to improve my vocabulary as well, and I don't know why when I want to write I am very slow and need a lot of time to think.
apparently i lack of the writing experience (someone can advise me on the best approach?) and that actually influences both writing and speaking

Wei, don't be discouraged! Writing is much more difficult than reading--I find this as I try to learn Spanish as well. The more you practice, though, the better you will get, and that will also help you with speaking English better. Best of luck!
