Writing is a kind of thinking behavior, so high school students' English writing course is also a kind of thinking behavior, which is bound to be affected by thinking.

In mother tongue writing, we always rely on the discourse structure to complete the expression of ideas, and guide the readers to draw the correct conclusion through the text. Due to the influence of Chinese culture, Chinese students use the text when they write English, and we know that the universal, natural, typical text is the interpretation of discourse in the context of English. So senior high school students in the foreign language writing, according to the Chinese thinking to write out the English composition, can not be understood or difficult to understand, that is, writing teaching is worth studying.

Therefore, in the teaching, we should make the students understand what the English text and writing in English method is. It should be said that English and Chinese are two kinds of thinking mode which are neither is good or bad, but if students do not understand the English text mode, they won’t write in English. So to improve the students' language ability is important, but more important is to guide them to know the inconsistency of language and thinking especially the student's thinking and the English expression of inconsistent, and helps them to use appropriate language form to express ideas clearly.

The main purpose of English writing is to train students to use the knowledge of the language flexibly, especially for the students to learn how to express them in real life.
