第二篇:植保总结

个人工作总结

2011 年对我来说是转折的一年、适应的一年、更是学习的一年,因为这一年里我的角色发生了本质的转换,从学校里的一名学生转变成了安监局监察大队的队员,此次的角色转换是我人生道路上的又一新的开始,新的阶段,新的挑战。

跨出了学校的大门,走出了学校的庇护,刚踏上社会的我还是有些许的不适应,但是在局领导和同志们的关心、帮助下,我还是很快进入了工作的状态、适应了现在的工作环境,在思想、学习和工作等各方面都取得了很大的进步。

对于这半年来的工作情况我做了如下的总结:

一、强化队伍建设、提高业务水平

安全生产监察队伍建设是安全生产监察事业的基础,是落实安全生产监督管理的关键环节和组织保障,同时,也是反映监察队伍精神面貌,文明执法、依法行政,展现安监局整体形象的关键所在。培养和造就一支思想过硬、作风优良、业务精通、纪律严明、依法行政的安全生产监察队伍至关重要。因此建队以来,我们在强化队伍建设、提高队员综合素质上不放松,始终坚持高标准、严要求、狠抓队伍的思想作风和组织建设。主要的举措有组织大队人员进行为期一个月的理论培训,有法律法规,文书处理,事故调查,大队管理办法等一系列理论知识的学习。之后又安排了实际工作的培训,做到理论与实践相结合,业务水平也有显著提高,为今后独立开展工作打下了坚实的基础。

第三篇:植保28班班务总结.

植保28班班务总结

时光从不肯眷顾每一个人,总是匆忙地来不及留下一个脚印就无影无踪。

从刚进大学校门到即将远赴实习单位定岗实习。作为班长,我和大家一起走过了近800个日子。想到这里,我内心有种莫名的激动。因为充溢着太多的甜美,太多的温馨,我们感奋不已;因为有太多的沉思,太多的感慨,我们探求不息,还有太多的情谊,太早的分别,我们深情依依!

身为班长,最真实的见证了班级发展的点点滴滴,见证了植保10028班成长的每一步历程。在从事班上事务的管理、各项活动的开展的过程中,清楚的看到我们班的进步与缺失。现就2010年到目前的工作做总结如下: 这两年来我带领本班班团委积极组织全班同学参与了学校学院开展的各种活动, 并在本班内自主开展了广泛而富有成效的各类活动,取的了良好的效果.我没有辜负大家的期望,带给了大家一个丰富的课余环境,同时带领大家朝着建设一个我们共同的大家庭而努力学习,进步!

一、班级制度建设

本学期,我班进入大三,我们班级在实现“深入加强日常管理,使同学加强自我管理”的班级管理目标上依然没有停下脚步。在这项工作中,主要围绕着三点来展开工作:

1.制定了制度,使班级管理具有更强的操作性,提出具体要求;

2.规范管理过程,做到民主决定班级走向;

3.明确责任管理,落实每个班委的责任。

在这基础上 , 扬长避短 , 争取使在稳步发展的基础上 , 寻求新的突破与新的提高。

二、干部队伍建设及其工作情况

班级的领导核心是班委会和团支部。各个班委,团委分工明确,责任到人,积极团结同学,班级日常管理稳定有序,班委团委之间密切配合组织各种有意义的活动。每一次组织活动,班委团委都尽心尽责,努力为同学们服务。经过大

一、大二的工作和磨合后,使我们之间增添了不少默契,各位班委在工作上已经能驾轻就熟。对班级的日常工作都相当熟悉,班委在明确分工的基础上加强有效合作,班级工作都能迅速有效的开展。班委会不定期的在一起研究班级工作,班委成员都能肩负责任,精诚团结。

三、活动方面

这学期领导和参与的活动有:

1.班费管理。班费实行“班长+生活委员管理,班委监督”。大笔开销需要班委会通过,并且每次活动的开销后或者每隔一段时间会对班费使用情况进行公布,接受全体同学的监督,实现了财务制度的公开、透明。

2,购买体育用品,定期组织同学进行体育活动;

3,先后组织各种类型的班会、和集体活动,促进班级融合。召开班会目的为了使同学树立民族自尊心、自信心和自豪感,树立与祖国休戚与共,血肉相依,为国献身的意志。同时为了了解社会主义伟大建设的伟大成就,使大家更热爱热爱祖国。

4,统计本班老师及同学的联系方式,并下发到各宿舍,建立班级QQ群,便于同学方便及时的交流沟通;

第1页,共3页

5,采用轮流制确定班级信息员对本专业有关的信息采集和有效传达;6,定期收集同学对班委及班级建设的意见和建议; 四,班风建设

在班风建设上,我们提出了 “赞美集体,欣赏个人”的口号,在发扬集体主义精神的同时,提倡加强个人发展,充分发挥每个同学的个人才能,展现每个同学的才华。在本学期里,我班同学在学习、文体活动竞赛、社会工作等各方面取得了优异成绩,同时涌现出一大批先进人物,学校的各项活动中都获得奖励。在班级干部的积极带动下,我班形成了团结、奋进、热情、创新的良好风气。整个班级感情融洽,同学们亲如兄弟姐妹,大家在学习之余能够主动加强交流,增进感情!

五、学习方面

在学风建设上,同学们不在有初入大学的迷惘,都有目标地、科学地、有效地投入到紧张的大学学习中,自我定位、自我选择、自我培养、自我约束能力都有了很大的提高。大家结伴上自习,共同探讨问题、相互鼓励、经常交流学习心得,蔚然成风。在学习生活中,大多数的同学都取得了令人可喜的进步。所有的同学都从以前时的不会学习、不适应新的学习模式的困境中走了出来,适应了大学特有的学习方式。

本学期大多数同学学风端正,基本上做到不旷课不迟到不早退,上课认真听讲,学习态度积极,交作业按时按质按量,同学们面对学习的态度很认真,各学科的学习上,成立学习兴趣小组,并取得良好效果。

对大学生而言,学习始终是头等大事。我们将一如既往的做好服务工作,将同学们在学习中的疑难问题传达给老师,以得到老师很好的解答。增加同学们学习信心,使师生互动。努力配合老师的工作,成为老师与学生沟通的纽带,把同学们的意见及时传给老师。关注学校的各种通知,及时传达给同学,便于同学们参加。如各种心理讲座,就业讲座等,这样可以增强同学们学习的信心,甚至可以解除同学们某些心理障碍。抓好同学们的上课出勤率,对无故旷课的同学作好思想工作。

六、目前班上存在的问题

1.班级凝集力有待提高,部分同学集体活动中表现的不够活跃; 2.个别班委会成员要提升个人能力,增强责任意识和服务意识 ; 3,全班男女同学互动不够;

4.班里个别同学偶尔上课迟到或旷课,对于某些课程态度不积极,课下自主学习意识不强,成绩不理想;

5,班委成员要加强与同学的交流沟通,了解和掌握同学的想法几意见,及时的做出相应的工作调整;

七、改进工作,再创辉煌

1.班级要保持形成优良的班风,使之能保持良好的精神风貌,在学校树立一个良好的形象,成为全校有影响力的班级。

2.有些同学对学校的制度、纪律管理产生“逆反”心理,导致思想、行为自由散漫,不利于班风建设。在这方面班委会要强化管理、落实制度,避免说做不一,并及时进行阶段性总结。最终,使同学们提高自我管理的能力。

3.狠抓班委会成员自身的纪律作风。建成一个作风正派、强健有力的班团委。着力提升班级凝集力,让所有同学想兄弟姐妹一样的生活在3班这个温馨大家庭中,切实感受到班级的温暖。

八、个人感想

1,学会交流沟通,学会倾听。在工作中、生活中,当别人向自己求助时,也许自己觉得很

第2页,共3页

不以为然的随口一说,可对于求助的人这件事也许是很重要的.自己的随口一说只会加重别人的茫然无助.很多时候都忽略了别人的感受,学会倾听非常重要。

2,换位思考。工作中生活中,我们每个人都要学会换位思考,立场不同,角度不同,对问题的看法也会不同.学会换位思考,带来的是对别人的理解,带来的是处理问题时清醒的头脑和正确的选择.3,感恩的心

在工作中生活中,无时无刻,有许多人都在默默的帮助自己,自己也许知道,也许不知道.可是没有别人的帮助,单凭自己一个人的力量怎么可能成功!在以后的人生道路中,无论何时何地,我都会报着感恩的心去做每一件事,我都会报着感恩的心面对我的朋友,成功属于大家!成功属于我们的班级!实习即将到来,大学生涯即将离开学校去往社会历练。作为班长,我学到了很多东西,在许多方面都获益匪浅。班上的同学来自不同的区域,各自的家庭背景也不同,但都为了努力成才的一致目的。这就要求我面对不同的对象,采取最合适的方法来与他们交流沟通。只有了解了所有同学们的想法,才能顺利地开展班级工作。多次组织活动也让我学到了很多,很多东西不是一个人能弄起来的,它需要一个强大的团结的班级做后盾。同时做事前要把所有可能发生的情况考虑周到,才能应酬帷幄,万无一失,避免到时候手忙脚乱。

回首这两年,这是我们真正思考大学、寻找目标、确定目标并为之努力的一个崭新阶段,这是我们更加团结友爱、收藏宝贵记忆、谱写大学生涯纪念册的一个学年,这也是我们这一届班委继往开来、辛勤付出、与全班同学共同进步的意义非凡的一个飞跃。

以一言以蔽之,我们班是一个蒸蒸日上的班集体,在两年的融合之后,我们逐渐形成了自己的班级特色。当然,我们也遇到过一些困难,但我们坚信在全班同学“万众一心,众志成城”的精神风貌上,我们一定会克服所有的困难,再创佳绩,更上一层楼,我们将走向更加辉煌的明天!

天行健,君子以自强不息!在新的征程中,我会谨记肩负的使命,铭记老师和同学的期盼,用百分百的热情和无限的创新去谱写属于3班的新华章!

① 非延续性动词不可与表示一段的时间状语连用。eg: The poor old man has died.(T)

The poor old man has died for three years.(F)The poor old man has been dead for three years.但在否定句中,可以与表示一段的时间状语连用。eg: He hasn’t come here for several days.② 非延续性动词与一段时间状语连用可采用下述三种方法:1)将非延续性动词转化为延续性动词:

come→ be here, go→ be there, die→ be dead,borrow→ keep, buy→ have, join→ be in/be a „member, leave→ be away, begin to study→ study,finish→ be over, get up→ be up, put on→ wear,catch a cold→ have a cold, wake up→ be awake,fall asleep→ be asleep, arrive/get→ be,lose→ not have, leave→ be away from

2)将时间状语改为过去时间,并用一般过去时代替现在完成时。eg: He has been in the army for three years.→He joined the army three years ago.3)用句型“It is+ 一段时间+since从句(从句中的谓语动词用非延续性动词的一般过去式)”表示eg: The old man has been dead for two years.→ It is two years since the old man died 练习:
