:..太原科技大学单靠“死”记还不行,还得“活”用,姑且称之为“先死后活”吧。让学生把一周看到或听到新鲜事记下来,摒弃那些假话套话空话,写出自己真情实感,篇幅可长可短,并要求运用积累成语、名言警句等,定期检查点评,选择优秀篇目在班里朗读或展出。这样,即巩固了所学材料,又锻炼了学生写作能力,同时还培养了学生观察能力、思维能力等等,达到“一石多鸟”效果。本科生毕业设计(说明书)语文课本中文章都是精选比较优秀文章,还有不少名家名篇。如果有选择循序渐进地让学生背诵一些优秀篇目、精彩段落,对提高学生水平会大有裨益。现在,不少语文教师在剖析课文时,把文章解体支离破碎,总在文章技巧方面下功夫。结果教师费劲,学生头疼。剖析完之后,学生收效甚微,没过几天便忘一干二净。造成这种事倍功半尴尬局面关键就是对文章读不熟。常言道“书读百遍,其义自见”,如果有目、有计划地引导学生反复阅读课文,或细读、默读、跳读,或听读、范读、轮读、分角色朗读,学生便可以在读中自然领悟文章思想内容与写作技巧,可以在读中自然加强语感,增强语言感受力。久而久之,这种思想内容、写作技巧与语感就会自然渗透到学生语言意识之中,就会在写作中自觉不自觉地加以运用、创造与发展。液压挖掘机液压系统设计这个工作可让学生分组负责收集整理,登在小黑板上,每周一换。要求学生抽空抄录并且阅读成诵。其目在于扩大学生知识面,引导学生关注社会,热爱生活,所以内容要尽量广泛一些,可以分为人生、价值、理想、学习、成长、责任、友谊、爱心、剖析、环保等多方面。如此下去,除假期外,一年便可以积累40多则材料。如果学生脑海里有了众多鲜活生动材料,写起文章来还用乱翻参考书吗?HydraulicExcavatorHydraulicSystemofDesign学院(系):机械工程学院专业:机械设计制造及其自动化(液压)学生姓名:简立瑞学号:201912030134指导教师:魏聪梅评阅老师:完成日期:········································································Abstract···································································1绪论 32挖掘机液压系统概述 93整机参数 ······················································134工作装置设计···················································································································································································································································································185挖掘机液压系统设计 ········································································································································221斗杆液压缸设计·············································222铲斗液压缸设计·························
