The main reason is the combination of coach's pursuing for re putation and student's aspiring for entering for college.

1前言从近年出现的体育高考兴奋剂话题，恰恰是这几年考试管理越来越严格后，出现的新问题。

the title compound was synthesized and its structure was studied in theory.the schiff base compound was synthesized by condensation of paeonol with furylfurylamine,then it was deoxidized by sodium borohydried.the energies,bound lengths,bound angles,the net charges of main atom and contributive percents of frontier orbital in the title compound have been calculated by software hyperchem 7.0 in half experience method.the yield rate of title compound was 65.6%.the result of calculation showed that the most of the bond lengths and angles in the system were in the the normal range,negative charge mainly concentrate on o1,o2,o3 and n1.the title compound behaves as quadridentate ligand.

目的合成标题化合物并对其结构进行了理论研究。方法以丹皮酚和糠胺为原料合成席夫碱，经硼氢化钠还原得标题化合物；使用hyperchem7.0程序，用半经验方法计算了化合物分子中能量分布、主要键长、键角以及主要原子的净电荷分布和前言轨道分布。结果标题化合物，收率65.6%；计算结果分析表明，分子中主要原子之间的键长、键角基本在正常的范围内；负电荷主要集中于o1，o2，o3和n1上。

As the translator pointed out in the preface to an English version of Dante's works, the violin and the piano make different sounds, but they can play what is recognizably the same piece of music.

In reface, the author analyzes the meanings of the theme of RPC's representativeness, and introduce the current research situation and the innovation of the paper, which paves the way for the theme's research.

前言：分析了人大代表代表性这一选题的意义，介绍了国内研究现状、本文的研究方法和创新之处，为论题的研究作了基础性准备。
