It is because that the students of different ages have great difference in intellectual structure, body and mind character , lifer exprience ., knowledge-level ., capacity of understanding , So project-learning curriculum in Primary school and Junior middle school cant copy the model of Senior middle school curriculum , and should open a suitable curriculum according to the body and mind character of students in Primary school and Junior middle school, although the National Ministry of Education have promulgated the project-learning curriculum in Senior mddle school.

因此，尽管国家教育部已经颁布了高中的研究性学习课程，但小学和初中的研究性学习课程不照搬高中课程的模式，而因根据其身心特点设置与之相适应的课程。

On the base of these, and the ideas of mathematical curriculum reform and the course of the reform of solid geometry, combining with educational reality and students" psychology, put forward some thoughts about solid geometry of middle school in future:(1) The arrangement of curriculum content should. give consideration to both the logical sequence of knowledge and the development of students" psychology, and make them united;(2) Paying great attention to the analogy of plane geometry and solid geometry;(3) Some respects remained to be strengthened about solid geometry in senior middle school;(4) Emphasizing the importance of conversion in solid geometry;(5) Stressing on the combination of solid geometry and algebra and other subjects;(6) The design of the content of solid geometry should have certain elasticity, and make solid geometry and modern education technology well combined.

在此基础上，又植根于近年来我国数学课程改革的理念和立体几何课程改革的进展，并结合我国的教育实际与学生心理，对未来中学立体几何课程的设胃提出若干思考：(1)课程内容的编排，要兼顾知识的逻辑顺序和学尘的心理发展相统一；(2)重视平面几何和立体几何的类比；(3)高中阶段立体几何有待加强的几个方面；(4)强调变换在立体几何中的重要性；(5)注意将立体几何和代数及其他学科相结合；(6)立体几何内容的设计要有一定的弹性，并注意与现代教育技术相结合。

During the course of the well-known "new mathematics" campaign, the status of Euclidean geometry was completely overthrown in I960" s. After deeply thought of "new mathematics", the standpoint that geometry curriculum should reflect the content and method of modern geometry and be in touch with the student" s real life was agreed on. Other countries have tried some significant attempts. We can find from some geometry textbooks that the methods of transform and vector have appeared as a normal part. Simultaneous, not only the new developments of geometry such as Topology have been referred , but also the connection between geometry and practice has been strengthened.In China, geometry curriculum is also in the during of innovation.

而学校几何课程在二千年的时间里一直没有多大的变化，直到二十世纪初"克莱因—培利运动"的第一次冲击，到60年代"新数学"运动的全盘改革，以及之后的深入反思，中学几何课程要反映现代几何学的内容和方法以及紧密联系于实践的观点已经受到普遍的重视，国外的几何课程已经在这方面做了不少有意义的尝试，从国外的一些几何教材中可以发现：变换、向量等工具已经作为正式的内容进入几何教学，拓扑学等几何的新发展也开始在教材中有所体现；几何课程与实践之间的联系更是在很大程度上得以加强。

The curriculum reform has its origin in solving problem of curriculum ossification,curriculum overload,and curriculum imbalance.

课程改革主要缘起于对课程僵化问题、课程超载问题、课程失调问题的解决。

It's one of trends to study hidden curriculum in current course studies, it also provided theory evidence to help to study the constitution of physical course (dominant course and hidden curriculum).

隐蔽课程的研究是当代课程研究的趋势之一，隐蔽课程的研究也为体育课程结构的构建提供了理论依据。

As an important part of education research and school curriculum, recessive course plays an important role in students' all-round development.

摘要隐性课程是课程研究中的一个重要内容，是学校课程的重要组成部分，具有显性课程无法替代的作用。

Only like this can we form our own way which will meet the requirements of the new era. Facing the reform, our teachers should renew our opinion, rerealize some basic matters such as education, Maths study and Maths teaching, and rechange our role through the study of the new subject theory and teaching case concerned. Teachers should put the theory into effect.

面对数学新课程改革，教师要及时更新观念，正确认识教育、数学学习和数学教学等基本问题，并通过对新课程理念和有关案例的学习，重新认识和转换自己的角色，以学习者、课程的开发者、教材的编写者和评价的参与者的角色，真正把新课程的理念落实到实处。

Section 5 bases on analysis of theory and these problems in foregoing 4 parts, then fundamental thinking on establishment of curriculum system on pre-professional education of teacher in local advanced normal universities is suggested at angles of training target and patterns, selection of curriculum value orientation, guideline and basic principle on reform of curriculum, etc. Meanwhile, major of Mathematics and Applied Mathematics is taken as instance and a configuration scheme of curriculum on pre-professional education of teacher in local advanced normal universities is developed with integrated local feature, multi levels, openness and selectiveness.

第五部分立足于前四部分的理论分析和问题剖析，从培养目标与培养模式的确立，课程价值取向的选择以及课程改革的指导思想、基本原则等方面入手，提出了构建地方高师职前教师教育课程体系的基本思路，并以数学与应用数学专业为例，研制了一个融地方性、层次性特点和开放性、选择性特色于一体的地方高师职前教师教育课程设置方案。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
