One possible version.

I have recently done a survey about how students learn English out of class. Almost all students read and recite English words. They think vocabulary is the most important for English learning. More than 40 students do a lot of written exercises. Some students go over their notes they have taken in class. However, only a few students spend time practicing listening and speaking.

  In my opinion, listening and speaking are the secrets of becoming a good language learner. We need to do lots of listening and speaking practice, such as watching English movies and listening to English songs. Also, chatting with foreigners can be helpful.
