Introduction Compared with frame structure building with ordinary rectangular columns, the one with special-shaped columns not only increase usable area, but also has better techno-economic targets by using materials of light weight walls.
It would be repaired by grouting materials after the reinforcement was completed.
This phenomena may be explained as that the strengthen material and old one could not work together until several cycle running-in process passed by, so more influence of the slip can be found in the curve.

After students modify their own writing works, they can click the model——“Ren Ren Bar” to put their works on the journals of Ren Ren, letting classmates, teachers and parents to appreciate their works and write down some evaluations for promoting the communications among parents, students and teachers.
CONCLUSIONS On the basis of relative theory study and practices, and with pupils’ cognitive level and factual teaching milieu, this paper has found out four effective strategies to cultivates students’ ability about collecting and consolidating materials for improving the quality of writing by using these materials in writing.
At the same time, these materials can stimulate students’ emotional point to a highest level, guide students to write down monologues from a diversified views and boarden students’ thinking of writing.
