There are some questions such as forest fire model selection, forest fire model updating, verifying simulation accuracy and so on in traditional forest fire spreading system. Study purpose is to build an innovative forest fire spreading simulation system based on DDDAS in this paper. The system can increase precision of forest fire spreading simulation by model base, model selection, model updating and so on. It can provide a strategic decision for forest fire save and new technologies demonstration for other related field of research. The research encompasses several major topics:(1) This paper brings up the term of dynamic data driven forest fire spreading simulation system and supplies new research approach and thought for forest fire spreading simulation study. The system framework was brought.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
