These achievements are hard won and should be appreciated. However, we are fully aware, the new period, and work in the countryside and the environment facing higher standards and requirements, provincial party Committee offered to high level build a comprehensive well-off society goal requires \no filth, dirty environment illegal buildings, into a well-off\pal party Committee also proposes to build into the well-off benchmark goals of the city. Compared with the superior claim, \of XX beautiful\Nong\nvironment there are a number of weaknesses and gaps, highlighted in the following five aspects: first, agriculture remained \d in the quality and low; short, value added of the industry chain is low; 123 fusion yield low employee age, low quality. \n smaller, specialized cooperatives throughout the County there were 3,396, but on the scale of too little. \d in production, management, services, decentralized, centralized, standardized, brand, information and organizational level is not high.

Thirdly, farmers continued to be \nt\d%ural labor force accounted for 70% over the age of 50. \Big\nce, such as the transactions of property rights, land replacement; public service supply gap, rural education, health care, pensions and other services can not meet the demand still difficult for poverty alleviation, with emphasis on poverty alleviation and 191. \d\\peasants.

十、教学效果：
1、通过习题检测，学生初步学会了物质的分离和提纯的常见方法，初步学会了常见物质的检验方法。能识别化学品安全使用标识。知道基本的安全措施和意外事故的紧急处理方法；
2. 通过课堂观察，学生以设计粗盐进一步提纯的实验方案为落脚点，体验到了科学探究的过程，可以运用以实验为基础的实证研究方法。在物质的检验，混合物的分离、提纯等实验过程中，学会运用观察、实验、查阅资料等多种手段获取信息，并运用比较、分类、归纳概括等方法对信息进行加工的方法。通过分组实验，交流讨论，大部分同学养成了实事求是的科学素养及合作意识。
3. 通过识记一些化学品安全标识，树立了安全意识，形成良好的实验习惯。 通过学习混合物的分离操作，了解化学在生产、生活和科学研究中的意义及作用，学会应用所学知识解决实际问题。通过学习废弃物处理方法，形成关心环境、爱护环境的意识。
十一、教学反思：
通过本节课的教学，观察到以下现象，引发联想：
1、学生课前准备不够充分，对本节所学内容欠缺必要的实验安全及目标性常识,建议课前先组织学生参观一下实验室及实验准备室以及药品储藏室。
2、学生课上活动虽多但较为无序，建议课前固定分组。
3、随堂实验学生观察到要求之外的内容但不敢发言，建议小结后，加入部分拓展。
4、课后学生对所学知识需要如何应用不甚了解，建议增加高考题练习！ 十二、随本课，开发PPT一份，将实验事故照片及实验室安全规定展示给学生，将课堂练习随堂处理；
十三、本课创新在于绝大多数时间及活动均由学生完成后有高考题练兵，符合新课标要求的同时，与高考考纲挂钩，既联系理论又结合实际，并且能将课时微格成若干活动时段，使课程的目标性更为明确，为教学目标的分段完成，提供了过程记录点，更便于课后反思！
ompelling.\h the \d, but the flood of scientific enough, before the treatment and water quality improvement after the treatment effect is not obvious, county-wide focus on river still largely inferior five water, swimming the River could not be found.
