Abstract：The intention of the work is to analyze, in a comparative way, the major differences between spoken English and written English. Analyses will include composing contents, expressive form, and how environmental factors affect the functional use of English in society. We can enhance English teachers’ awareness of the differences and improve their English teaching. We also hope English teachers pay attention to the differences between the two through their teaching.

Keywords: spoken English; written English; differences; English teaching
