篇一:活处处有学问
生活是一座金矿,待人去挖掘,有人说故事源于生活而高于生活,多少次经历告诉我,故事里的学问同样来自生活。-------题记
暑假是轻松的,自在的,但若是轻松自在过了头,便成空虚了。生活,还是充实点好。于是,我选报了美术专业班,每天背着画板,频繁穿梭于家与学校之间。拿着画笔在纸上涂鸦,画人、画物。这个班的班主任是一个三十岁左右的女教师,从不曾见她跟学生红脸,整天乐呵呵的。或许因为是暑假的原因,而且这个班的许多学生又都是高中生,经常会有一些调皮的学生故意逃课、旷课、故意迟到。一次,两次……
她从不多说什么,只是告诉那些学生以后不要再迟到了,就此了之。但这决不代表她不负责任,我经常看到她在上课时望着那些学生画画,望着望着就无法移动目光。我刚开始不知道她究竟在想什么,又想干什么,但是几天后,我知道了。
那天早晨,微雨,空气有些潮湿,但很清爽,让人惬意。在专业老师还没到时,她已早早的来到教室,热情的跟每个人打招呼,脸上依旧漾着笑意。七点三十分,她开始点名,仍然有几名学生未到,等了约有三分钟后,那几名学生才陆续走进教室。不知什么原因,专业老师还没有到。于是归、,她借着这个时间个我们将乐一个故事:有一个刚毕业的大学生,再一家很有名气的大公司里工作,因工作勤恳,得到了老板的器重,他的事业也蒸蒸日上。按说这个年轻人足可以在不久的日子里飞黄腾达,但一件小事却改变了他的命运。
有一天,他收到了一份邮件,这份邮件应当及时交到老板的手里,而此时,老板已经开车回家了。于是,他带着这份邮件到了老板家门前,老板看见他十分高兴,邀请他进屋喝杯茶,他推辞不掉,只好进去了。然而,在换鞋的时候,他发现自己的袜子上有个小洞。但此时说走必将 引起老板的不满,他只好硬着头皮走了进去。老板盛情招待,亲自为他沏茶倒水,这使他更不自在。老板不小心碰掉了桌子上的打火机,弯腰去捡,年轻人也急忙弯下腰去。恰在此时,年轻人看见老板看着他的袜子皱了皱眉头,他知道老板看到了他袜子上的小洞。当老板直起腰时,脸上的表情十分古怪,语气也有点生硬,年轻人随便聊了几句,就起身告辞,老板也不在挽留他。从那以后,老板渐渐疏远他,无论他如何努力,他知道自己留在这家公司已经没有任何发展前景,于是,被迫辞职。
她讲完这个故事说,如果不是因为年轻人袜子上的一个小洞,他现在已经飞黄腾达了。她的故事讲完了,整个教室静悄悄的,每个人脸上的表情个不相同。这是,专业老师到了,她和专业老师打了个招呼,就转身向办公室走去,只留下身后我们这些思考着的人儿。从那以后,再没有一个人迟到,像是一个奇迹。 我逐渐明白了那个故事里的学问。它告诉我们:做事要从小事做起,从细节中就可以看出你是怎样一个人的。同时,她也告诉了那些迟到的学生,从他们的日常行为里,就可以看出他们的学习态度,虽没说要让他们今后怎样去做,却也不言而喻
我突然想起了这样九个字“一屋不扫,何以扫天下?”我敬佩这位老师,因为他的别具一格,她注重素质教育,赏识教育。她清楚的认识到这个年龄阶段学生的叛逆心里。故事就是生活,故事里的学问也同样来自生活,我开始慢慢懂得,生活处处有学问。
篇二:生活处处有学问
小老虎有两个好朋友小熊和小鹿,去年小老虎给小熊量身高在向日葵的三分之一处,可今年小熊却变矮了,这是为什么呢?
小鹿说:“我们去问问小兔吧,它可是植物专家啊!”到了小兔家,小兔说:“今年我给向日葵浇水、施肥、晒太阳。”小熊说:“我可是每天都洗澡,没事儿就晒太阳,我想这不是解决问题的好办法。”小老虎说:“是啊,小熊天天喝牛奶,瞧,它长得多么强壮啊!怎么没去年高呢?”
小动物们都在仔细的思考着这个问题。突然小鹿发言了。它说:“这下,我明白了,小兔子今年对向日葵照顾的特别精心,向日葵比去年长的粗壮、高大了许多。而小熊还是一样的成长速度,所以就被向日葵落下了呀。”
通过这件事,我明白了生活处处有学问,只要认真观察,就能发现许多奥秘。
篇三:生活处处有学问
前几天,叶老师忽然有了个主意,让我们把黄豆种子、红豆种子分别种下,并且让它们长出芽来。这真新奇,我领了豆,直奔家里。
我先把豆子浸泡在水里,过了几小时后,我再把红豆和黄豆分别放在稻草中间,按时浇水。第一天,我把稻草分开一看,红豆已经长出了一点芽。那芽又白又尖,还很粗。我高兴地想:“哈哈,现在芽长出了一点,再过几天,芽会越长越大,再长出叶子,然后…”我越想越开心。我转头一看,立刻变得满面愁云。那黄豆又大又长,却在土里丝毫未动。“也许,是我浇水太少,它会长出来的。”我想。第二天,我一看就傻了眼。红豆种的芽长大了许多,可黄豆却从黄色变成了淡黄色,甚至有些变成了黑色,腐烂掉了。我赶紧去问妈妈,妈妈不知道。我翻了许多书,也查不到。我急得像热锅上的蚂蚁——团团转。打破沙锅问到底,我决定明天去问老师。
第三天,我急忙去问叶老师。我终于知道了原因。原来,这豆子尽管老了,也要呼吸空气。红豆经常放外透气,经常呼吸新鲜空气。而黄豆被包装了,说不定已憋死了。
篇四:生活处处有学问
谁说“酒香不怕巷子深”?大城市就甭提了,就说我们这个小镇吧,黄金地段的商店也鳞次栉比呀!这么多商店怎么才能吸引顾客呢?取一个好店名,就显得相当重要啦!
瞧,有的店名明确道出了自己的经营方向。“百草堂”——一看见这店名,你就知道是药房了。“神农尝百草”的故事,大家耳熟能详。传说神农一生下来就是个“水晶肚”,五脏六腑全都看得见,还看得见吃进去的东西。那时候,人们经常因乱吃东西而生病,甚至丧命。为此,神农决心尝遍百草,救死扶伤。取这个店名,也传达了“顾客至上”的服务宗旨,多亲切呀!还有“延生堂诊所”,“假日旅行社”,“嫂子家政”,“一品香”餐馆,也都采用了这种方法。
有的店名巧用了各种修辞手法,显得妙趣横生。“泊来客”——这‘泊来’,是漂泊而来的意思,显然,这家商店里琳琅满目的“客人”都是外国国籍。有法国的葡萄酒,丹麦的曲奇饼,日本的糖果,美国的朱古力,还有韩国的化妆品……这么多“客人”聚集在这里,好像正召开一个万国博览会呢!
这位商家也不示弱,他采用比喻的手法为自己的商店取名:“架金桥”——这是一家中介贷款公司。在商家和银行之间架起了一座通往财富之门的金桥,这不正体现了它存在的价值吗?
还有的店名运用了谐音。这家“发新社”——做头发的,显然想粘点儿“法新社”的名气。更搞笑的是这家卖衣服的店子,居然取名“衣拉客”!“衣拉客”这名儿,不仅把商家对顾客的热情欢迎倾注到商品上,别有情趣,而且念起来,就成了“伊拉克”,这出奇制胜的幽默,真令人忍俊不禁。
再看这家店老板,一定是富有雅趣的文化人吧!他借用古诗句来为自己的茶楼命名——“柳暗花明”茶楼,让人一下子就联想到“山重水复疑无路,柳暗花明又一村”的千古名句。茶楼里有假山,有小桥流水,莫不让人有返璞归真的亲切感。
祖国的语言文字是多么的丰富奇妙啊!它和我们的生活联系得如此紧密,我们真应该学好它,用好它!
“世事洞明皆学问”,的确是呀!街头商店的店名是我们最常见,而又最容易忽视的事物。小作者不仅留心到了,而且在精心搜集的基础上,仔细归纳,深入思考,从中体会到了祖国语言文字的丰富奇妙,并认识到学好、用好祖国语言文字的重要性。这样的选材和立意,既洋溢着鲜活的时代气息,也体现出作者对生活的热爱,对祖国的热爱。
篇五:生活中处处有学问
一天晚饭后,我靠在沙发上看动画片,爸爸走过来,拍拍我的肩膀:“乖女儿,帮爸爸把烟灰缸洗一洗。”我起身一看,哇,好脏的烟灰缸,几个浸得发胖的烟蒂浮在水面。端起烟灰缸,一股呛人的烟味直刺鼻孔。“爸爸,你怎么老爱往烟灰缸里倒水,把烟灰缸弄得这么脏?”爸爸不好意思地朝我笑了笑。我拿着烟灰缸气呼呼地来到阳台,顺手把烟灰缸里的水倒在菊花盆里。
第二天,我意外地发现菊花上一只只黑黑的小蚜虫不见了。仔细一看,蚜虫都死了,一个个小尸体躺在花盆里。怎么会这样呢?难道是因为昨晚我往花盆里倒入……
为了证实这一想法,下午一回家,我就放下书包主动去帮爸爸清洗烟灰缸。我像昨天那样,把烟灰缸里的水倒在一棵有蚜虫的花上,然后目不转睛地观察蚜虫的反应。起初,蚜虫没有什么动静,过了一会儿,它们有些烦躁,开始在花枝上爬来爬去。几个小时过去,我发现蚜虫有的死在枝叶上,有的死在花盆里。原来,烟蒂泡出来的水竟是治蚜虫的“良药”。我为此高兴得手舞足蹈。
现在,家里的花要是长蚜虫,我就泡一些烟蒂水喷一喷,保准“药”到虫死。这个意外的发现让我明白了,生活中处处有学问,只要你用心观察,知识就在你的身旁。
篇六:生活处处有学问
去年夏天,天气热得很,晚上必须把窗子开得大大的,让空气流通,才觉得稍微舒畅些。
一天夜里,我躺在铺满竹片的床上,连枕头也是竹制的,可还是热得直冒汗。汗珠大滴大滴地渗进竹片的缝隙中,第二天一大早,我觉得头发湿露露的,便摸了摸头发,才一两天没剪就像几年没修剪的杂草了!我用手拉了一下头发,估算了一下,起码有五厘米长呢!于是我想到冬天头发几个月才剪一次,可夏天为什么头发长得快呢?这让我百思不解。
一天,妈妈带我到书店买书,偶然间我在一本《蓝猫淘气三千问》中看到我那百思不解的问题“头发为什么夏天长得快,冬天长得慢?”,我带着兴奋的心情翻到那页仔细地阅读起那篇文章。
原来,夏天天气热,激活了生发素,毛囊中的生发素便昼夜不停地工作,就像人注射了兴奋剂一样,可冬天天气冷,生发素便减缓了头发的生长。头发几周才长三四毫米。要是冬天太冷,那他一个季度可能只需剪一到两次头发就行了。
从中我体会到生活中处处有学问,只要你仔细观察就会发现。

生活处处有学问作文(一)
学问不仅仅体现在科学上,其实,生活中也有学问,他们只是被大家忽略了而已,只要你有心,一定会发现的,我就发现了一个学问——苹果能让其它的水果快速成熟。
有一天,我和妈妈去买水果,妈妈买了一袋子的猕猴桃。我迫不急待地拿了一个猕猴桃来吃,猕猴桃硬得都能把我的牙给磕掉了。妈妈笑着说:“现在猕猴桃还是生的,不能吃呀!”听了妈妈的话我连忙把猕猴桃放进了袋子里,问妈妈这猕猴桃什么时候才能吃,妈妈说:“最快也要两三天,你先吃个苹果吧!”我拿起一个苹果看了看,但心里却想着桃,所以随手就把苹果扔进了装猕猴桃的袋子里。
第二天,一想到猕猴桃我的口水就直流,于是就打开袋子看了看,并捏了捏,哇,猕猴桃这么快就熟了,妈妈不是说最快也要两三天吗?我很好奇,就上网查了查,原来苹果能加快其他水果的成熟速度。
看来生活中的学问真不少呢?只要我们善于观察和探索就一定能发现的。
生活处处有学问作文(二)
生活中处处有学问,我们只要细心观察,一定会有许多意想不到发现。
一天,我高高兴兴地来到家里,不小心把红豆和黄豆都混在一起。我耐心得分着豆,过了好一会儿我才分了十分之一的豆。我生气地把桌子一推,豆掉下来了,我发现红豆差不多全都掉下来了,但是也有一些黄豆。我就一直推,不一会儿就把豆都分开了。我就问奶奶:“奶奶我一推桌子红豆就掉下来了?”奶奶回答说:“因为红豆是圆的,黄豆是椭圆的。圆的东西会滚,所有红豆会掉下来的。”
在一个炎热的夏天里,我发现有许多人都穿淡颜色的衣服,我就走过去问他们。他们说的意思都差不多,“因为白色的衣服里有白色素,白色素会吸收冷的气体,我们就觉得很凉爽。假如是冬天我们就会穿黑色的衣服,因为黑色会吸收暖气,我们就会觉得很暖和。”
有一次我外婆家的母鸡生了许多蛋。外婆把煮好的鸡蛋都放在了一个盒子里。有一天鸡又生了好多蛋,我就把它们都放在了盒子里。我把生的也放在里面里,我就跑过去告诉姐姐,姐姐说:“没关系,我们把鸡蛋全竖起来,竖不起来的就是生的。”我照着姐姐说的,没过一会儿就把鸡蛋全分开了。
生活中真是处处有学问呀!
生活处处有学问作文(三)
生活中要善于发现。罗丹说过:“对于我们的眼睛,不是缺少美,而是缺少发现。”发现需要用心灵、智慧去思考,要“打破砂锅问到底”,多探究才会有收获。
有一次,我去公园赏荷叶,只见大大的圆盘上点缀着几颗晶莹剔透的“珍珠”。咦?它为什么浮在荷叶上?一般的水不就是渗在里面了吗?我立即来了神,转过身急切地问妈妈,妈妈看着我疑惑的眼神,一下子就看透我的心思,我还未开口,妈妈就说:“这就是大自然的一种奥妙,(m.lz13.)也就是你以后学习物理时要学习的“张力”。”
我回家后,二话不说就进了我的书房,搬出我的《百科全书》。我看了恍然大悟,原来当水滴落在荷叶上时,荷叶与水珠间形成一个高度的接触角,使之聚集成珠状而不扩散。荷叶的表面附着无数个微米极的蜡质乳突的表面又附着许多与其结构相似的纳米颗粒。科学家将其称为荷叶的微米纳米双重结构。正是具有这些微小的双重结构,使荷叶表面与水珠或尘埃的接触面积非常有限,因此产生了水珠在荷叶上滚动的现象。
我把这个奥秘告诉了妈妈,妈妈高兴的抚摸着我的头说:“好孩子,善于观察,处处皆学问,妈妈真替你感到高兴。”
我真的也很惊讶,大家经常见的荷花,竟然有这么多的奥秘和知识,都是我们不知道的。我以后一定要多多观察,勤思考。如果,看到、听到,却不去思考,不去探究,不去总结,是得不到提高和感悟的。走马观花的观察是不会有所发现的,真正有价值的是,往往不会轻而易举的露面,它会隐藏在某一点,某个角落,等你去博览群书的用你的只会去开启它,挖掘它,揭开它神秘的面纱。在每天的学习、生活中,处处留心皆学问,不是吗?

生活中处处有学问
星期六,我和哥哥去公园玩。我来到公园的草地上,刚要坐下,看见一只蚂蚁发现食物,可是,过了一会儿,成群的蚂蚁排着整齐的队伍爬了来。我感到很奇怪,为什么一只蚂蚁找到食物,就有许多的蚂蚁也会爬来?我带着这个问题回家查找了许多书籍,后来找到,原来蚂蚁们寻找食物都是各管各的。可是,如果有一只蚂蚁找到食物,这只蚂蚁就会用自己的触角发出“信号弹”,周围的蚂蚁就会收到信号,就来搬运食物,把食物搬回蚁巢。这时,我又产生另一个问题:为什么他们搬运食物回巢不会迷路?于是,我做了一个实验,把一些面包放在草地上。不久,果然有许多蚂蚁来搬运。它们准备回蚁巢时,我找来一块拳头般大的石头,挡住了它们的去路,它们立刻散成一团。过了一会,一只蚂蚁找到了去路,又排着整齐的队伍继续前进。后来,我问哥哥,哥哥回答:“蚂蚁肛门会排出一种特殊的分泌物,别的蚂蚁就是靠这个找到路的。” 经过这件事,让我懂得:原来蚂蚁也那么团结友爱,我们应该学习蚂蚁,团结友爱的精神。

这可能是由于胃里装满了食物~肚子饱胀~在重力的作用下运动时剧烈震荡~牵扯了肠系膜~发生恶心、呕吐、腹痛的症状。所以运动前不要大量喝水~饭后不要马上进行剧烈运动~应该在饭后一个小时再运动。老师的一番讲解~让我终生受益匪浅。我懂得了~活动时~特别是参加比较剧烈的运动或比赛~身体要消耗大量的水分和营养物质~需要适时地得到适量的补充~才不致影响身体的健康。喔~原来运动时~在“吃喝”上还有这样大的学问哩。
我谨遵这样的教诲~加上大的活动量~才练就了一个好身体。看似微不足道的玩耍嬉戏之中~都蕴藏着科学知识啊~多得些知识绝不是坏事。“流水不腐~户枢不蠹。”~人人都要多运动。,指导教师 贾智君,

小学数学综合实践活动课的生命
---创新能力的培养
培养学生创新能力是知识经济时代对每一个教师发出的呼唤,也是当今数学综合实践活动课的生命。因此,在数学综合实践活动中必须渗透创新意识,着力培养学生的创造性思维,落实、加强创新教育。在实践中,我们进行了一些尝试和探索。
一、激发学生的创新兴趣
在教学中,我经常鼓励学生畅所欲言,大胆探索,标新立异,引发学生的创新活动,并及时捕捉学生的“智慧火花”与“灵感”对他们敢于创新的举动加以表扬、肯定,使学生养成敢于探索、敢于开拓,勇于实践的精神。
创新意识是一种发现问题,积极探求的心里趋向。为了激发他们的创新兴趣,我们常在新课引入时用游戏、故事、图片、试验等激发学生的好奇心,这样极大地激活了他们求知的欲望与创新的兴趣,同学们个个情趣高涨,收到了事半功倍的效果。
二、创设探究内容,培养学生观察能力。
教学成功与否,学习效果如何,取决于学生对学习有效参与的程度。眼睛是思维的窗口,“看”是获得知识的必要前提。教学中教师可以根据教学内容的需要,给学生创设充分观察的机会,引导学生主动探索知识的形成过程,感受学数学的趣味和作用,体验数学的魅力,使教学过程成为师生充满快乐、涌动生命活力的生活世界。例如,教学“什么是周长”这一课时,我就地must strictly enforce the hot examination and approval system, holidays, hot work approval to be upgraded. (2) the fire operation, guardian and extinguishing equipment in place. (3) key parts person regulation: welding site: track guardian, dangerous goods, warehouse: warehouse workers, dormitory: 1, the implementation of points of dormitory culture construction: construction, environmental health into the construction organization design, developed and civilized construction requirements, no rough construction, projects in accordance with the construction programme of the Department organize the implementation, followed by the project leader, the pany ... Education or punishment. 1, corrective and preventative measures corrective measures: (1) by the project security officer in identifying causes, in the context of findings make remendations for corrective and preventive actions. (2) under the present proposal, formulated by the security staff corrective measures, for examination and approval. (3) safety officers monitor the implementation of corrective measures, record the corrective measures process. 2, preventive measures: (1) normal operation safety ensuring system integrity and is fundamental to prevention. (2) implementing a prehensive, standardized management processes, staff, education workers and enhance awareness of self protection,
取材,在操场上捡了一片榕树叶给学生看,边让学生细心观察边问:“叶子的边是怎样的,”当学生回答:“有一些小齿”时,我就接着说:“你能把它的所有小齿不重复地摸一遍吗,”学生说:“行~”我就让学生摸一遍。接着让学生认真观察多媒体演示,沿着树叶的边线,一笔描出树叶轮廓的情形:第一次描是正确的,第二次描是少描一些的,第三次描是多描一些的。要求学生观察后,作出判断,并说明理由。结果学生通过观察和对比,结合自己实际摸树叶边线的轮廓,懂得了要先确定描的起点,最后要回到起点(终点),这样描才不会多描,也不会少描,初步体会了有关“周长”的内涵,接着我让学生在身边找一些物体摸一摸它们的边线,再一次领悟周长的含义,最后我让学生把物体按在练习本上一笔画出它的边线。这样做,不仅把生活问题提炼成了数学问题,开拓了教学资源,同时也使他们体会数学就在身边,培养了学生的学习兴趣,激活了学生的思维,提高了学生的观察能力。
三、创设思考机会,体验成功的喜悦。
教学中最重要的是让学生有思考的机会,要尽量让学生去发现一些问题,研究一些问题,讨论一些问题,感悟一些问题,使学生在解决问题的过程中体会“我能行,我快乐”的感觉,体会成功的喜悦。在学习完“千克、克、吨”的知识后,我让学生思考这样一道题:一架天平配有3个10克的砝码。想一想怎样才能知道多少粒花生约重50克。这道题目学生在日常生活也许有must strictly enforce the hot examination and approval system, holidays, hot work approval to be upgraded.

(3) key parts person regulation: welding site: track guardian, dangerous goods, warehouse: warehouse workers, dormitory: 1, the implementation of points of dormitory culture construction: construction, environmental health into the construction organization design, developed and civilized construction requirements, no rough construction, projects in accordance with the construction programme of the Department organize the implementation, followed by the project leader, the pany ... Education or punishment. 1, corrective and preventative measures corrective measures: (1) by the project security officer in identifying causes, in the context of findings make remendations for corrective and preventive actions. (2) under the present proposal, formulated by the security staff corrective measures, for examination and approval. (3) safety officers monitor the implementation of corrective measures, record the corrective measures process. 2, preventive measures: (1) normal operation safety ensuring system integrity and is fundamental to prevention. (2) implementing a prehensive, standardized management processes, staff, education workers and enhance awareness of self protection,
经历过,是一道既普通又平凡的题目,较紧贴生活。经过学生的认真思考,不少学生写出了解决这个问题的方法。例如:(1)1次称10克,称5次。只要数一数第一次称的花生有多少粒,再乘5就知道了。(2)先称2次,每次称20克,再称10克,合起来就是50克。(3)先称30克,再称20克,合起来也是50克,再数一数有多少粒。最后我给学生提供了题目里所提到的工具及材料,让学生实际称一称,验证他们的设想。学生根据题目的信息,运用所学的知识,解决了身边的问题,并通过自己的实践验证结果,感受到了思考的快乐,成功的快乐,课堂生活的快乐,同时对学习数学也充满兴趣~
四、引导学生自主探究和创新能力
在数学活动中,学生通过动手动脑自主探索、大胆猜想、合作交流、实验验证、积极思考等方式学习数学、运用数学,更有利于他们创新能力的培养。在教学:“一位数除三位数(商是三位数的除法)”后,学生在解答这道题目:班上开联欢会,同学们布置教室,按照下面的顺序挂气球。“蓝黄黄红红红红蓝黄黄红红红红??”,买了48个红气球,要买几个蓝气球,几个黄气球,要求学生利用自己手中的学具,小组摆一摆,探索有多少种解法。学生马上动手摆学具。有的摆圆片,有的摆小棒,争先恐后地操作起来。操作了片刻,学生热烈地讨论着,有的说可列式为48?4,12(组),(蓝气球)12×1,12(个),(黄气球)12×2,24(个);有的说在一组气球里:红气球是蓝气球的4倍,must strictly enforce the hot examination and approval system, holidays, hot work approval to be upgraded. (2) the fire operation, guardian and extinguishing equipment in place. (3) key parts person regulation: welding site: track guardian, dangerous goods, warehouse: warehouse workers, dormitory: 1, the implementation of points of dormitory culture construction: construction, environmental health into the construction organization design, developed and civilized construction requirements, no rough construction, projects in accordance with the construction programme of the Department organize the implementation, followed by the project leader, the pany ... Education or punishment. 1, corrective and preventative measures corrective measures: (1) by the project security officer in identifying causes, in the context of findings make remendations for corrective and preventive actions. (2) under the present proposal, formulated by the security staff corrective measures, for examination and approval.

求蓝气球列式为:48?4,12(个),而红气球是黄气球的2倍,求黄气球:48?2,24(个);有的说:每组气球中,红气球是蓝气球的4倍,而黄气球是蓝气球的2倍,因此先求蓝气球的个数,再乘2就求出黄气球的个数,即:48?4,12(个),12×2,24(个)。学生通过自主探究后,结合自己的思考,想出了这么多合情合理的、富有创造性的方法,我为他们的精彩回答拍手叫好,学生们也因此兴奋不已,掌声和表扬声在课堂上响了一次又一次,师生都沉浸在操作活动、发现规律的体验和乐趣之中。这样教学,使学生有成功的体验,开放了课堂,形成张扬学生个性的气氛,展示出学生不同的体验。
五、精心设计,优化练习,主动创新。
练习是一种有目的、有指导、有组织的学习活动,是学生掌握知识形成技能与技巧的基本途径,在小学数学教学中占有重要的地位。优化练习要处理好质与量、新与旧、难与易的关系。也就是说在设计练习题时,要注重练习题的质量,要设计一些有一定坡度和难度的题目,即要考虑旧知识的巩固,又考虑到新知识的铺垫,难易有度。特别要设计一些有创新的练习,让学生在练习中主动创新。优化练习,就是练习要灵活多样,有趣味性。学生在练习时要有宽松的氛围、愉快的情绪,这样,学生乐学、乐练。练习要有层次性,要由浅入深、循序渐进。同时,要有利于激发学生的创造思维的火花。还可以设计一些实践和操作的练习,如:在教完“圆柱体”的体积计算公式时,下课之前,我向must strictly enforce the hot examination and approval system, holidays, hot work approval to be upgraded.

(2) under the present proposal, formulated by the security staff corrective measures, for examination and approval. (3) safety officers monitor the implementation of corrective measures, record the corrective measures process. 2, preventive measures: (1) normal operation safety ensuring system integrity and is fundamental to prevention. (2) implementing a prehensive, standardized management processes, staff, education workers and enhance awareness of self protection,
学生布置了作业:“我们已经学了长方休、立方体、圆柱、圆锥的体积计算公式,这些图形都是规则图形,那对于一个不规则图形(如一块石头),它的体积怎样来求呢,课后请同学们去研究一下,可以请教别人,也可以查资料,明天数学课上,展示、汇报成果”。再便如:在教学长方体、正方体表面积之后,我让学生在课外用纸板制作一个长10厘米,宽8厘米,高5厘米的纸盒。而且要让学生思考:怎样剪、怎样粘可以制成一个符合要求的长方体,让学生通过动手制作,明白要做一个标准的长方体,必须在适当的边上留出适当的空白粘边,否则无法粘上去。这些教学改变了“耳听口说”的简单化学习模式,让学生多种感官参与学习,使学生能进一步理解和接受知识。在练习中,让学生主动去创新,这对培养学生的实践能力和创新精神,能起到积极的作用。
六、 联系生活,拓宽创新空间
数学知识源于生活,生活中处处有数学、在教学中,我们要根据需要补充一些生活中的数学活动,拓宽学生创新的空间。学校要进行校园建设,决定对校园进行改造,修建花坛。针对这种情况,我抓住时机,向学生提出活动研究课题:“校长决定向全校师生征集花坛的设计方案,请同学们帮学校设计一下。同时想一想,建花坛需要考虑哪些问题,怎样解决,”对学生而言,这是一个比较大的综合性问题,其中蕴含了许多的数学问题,需要调动多方面的知识储备并需要结合学生实际,从不同角度考虑。must strictly enforce the hot examination and approval system, holidays, hot work approval to be upgraded. (2) the fire operation, guardian and extinguishing equipment in place. (3) key parts person regulation: welding site: track guardian, dangerous goods, warehouse: warehouse workers, dormitory: 1, the implementation of points of dormitory culture construction: construction, environmental health into the construction organization design, developed and civilized construction requirements, no rough construction, projects in accordance with the construction programme of the Department organize the implementation, followed by the project leader, the pany ... Education or punishment. 1, corrective and preventative measures corrective measures: (1) by the project security officer in identifying causes, in the context of findings make remendations for corrective and preventive actions. (2) under the present proposal, formulated by the security staff corrective measures, for examination and approval. (3) safety officers monitor the implementation of corrective measures, record the corrective measures process. 2, preventive measures: (1) normal operation safety ensuring system integrity and is fundamental to prevention. (2) implementing a prehensive, standardized management processes, staff, education workers and enhance awareness of self protection,
整个活动分为三个层次:一是考虑花坛的布局、形状 、大小等因素初步确定设计方案;二是研究各种用料用费问题;三是结合学校实际选择花草品种。由于活动内容的生活化,学生纷纷走出教室,跑到操场上,比划、测量,自觉将数学知识与生活联系起来。
孩子的潜能是巨大的,重在教师的开发、引导,有创新才有进步,有创新才有发展,有创新才有实力,有创新才能腾飞。在数学综合实践活动中,我们要尽一切努力激发学生的创新兴趣,创新自己的教学理念,多鼓励、多呵护他们,珍惜学生的奇思意想,发挥好教师的主导和学生的主体作用;让数学综合实践活动课成为学生创新的源泉。

科学在我身边
——醋的作用
三、(4)班 王凯宇
指导教师:苏新秀
科学知识虽然是很深奥的,没几个人能真正懂,但是科学现象却是无处不在的,已融入了我们的生活。今天,我要向大家介绍的“醋”就是其中之一。
醋是我们生活中很平常的一种调料品,这是众所周知的。其实,它不仅可以帮助我们烹调出美味佳肴,它还有很多其他的用处呢。下面就让我来介绍一下我的发现吧。
快过年了,妈妈正忙着做清洁呢,我就当起了小助手。她擦完玻璃拖完地又去洗厨房的厨具。洗到茶壶的时候妈妈叫我把醋瓶子给她。我好奇地问:“您拿醋干什么呢,”妈妈说:“洗茶壶里的水垢呀。”“醋能洗去水垢,”我半信半疑。只见妈妈往茶壶里倒了些醋,再加上点温水,泡了大概十几分钟,然后很轻易的就洗去了水垢。没想到醋还有这神奇的功能,比那洗涤剂还管用。我忍不住问妈妈:“醋还有些什么功能呢,”妈妈告诉我“醋能去污除味,在生活中作用可大了,你在以后的生活中会慢慢地发现的。”
第二天,我在玩耍的时候,一不小心弄了几滴胶水在新衣服上,这可怎么办呢,胶水可不好洗呀,被妈妈知道了一定会挨骂的。这时,我突然想到了醋。妈妈不是说它能去污吗,它应该也能去除衣服上的胶水吧。抱着试试看的心理,我马上行动起来。我在粘有胶水的地方
蘸点水,然后用棉签蘸些醋抹在污点处,再使劲搓洗,没想到胶水印记还真的慢慢淡了,然后我再用清水清洗。还真让我把衣服上的胶水洗去了,醋的威力可真大呀~它今天可帮了我一个大忙。
没过几天,在一次饭局中,弟弟不小心被鱼刺给卡住了,他急得大哭大闹,大家都慌了,你一句我一句地说起来,不知怎么办才好。还是妈妈有主意,“快喝几口醋吧~”“对,对,快喝点醋。”其他人也跟着说。“这也用醋,”我惊讶了。此时弟弟已经喝了几口醋,嚷嚷着“酸死了~酸死了~”“耶~好像不怎么卡了。”弟弟叫起来。外婆又让他吃了几口菜,还真没事了。眼前的一切让我看得一愣一愣的,妈妈看出了我的疑惑,说:“醋能软化鱼刺,鱼刺变软了,再用菜把它带下去就不卡了。”“醋还有软化鱼刺的作用,”在好奇心的驱使下,我立即实验了一下。我把桌上的骨头和鱼刺拣几个放进一个杯子里,然后再往杯子里倒些醋,把骨头和鱼刺泡起来,过了几分钟,夹起骨头一摸,还真是软软的,鱼刺也软得像一根线。真不敢相信醋竟有这么大的威力~
我对醋产生了浓厚的兴趣,决定要弄清楚它。于是我上网查阅了有关醋的各方面知识。原来,醋的主要成分是醋酸,是酸性物质。它能去除污质、软化鱼刺都是运用了“酸碱中和”的原理,也就是酸性物质和碱性物质混在一起就会发生化学反应。这可是一种神奇的反应~
醋的作用还有很多很多,例如:快速除鳞、去油迹、防脱发、消毒杀菌、治疗脚气、养花等等。醋还是一种很好的保健品呢,它能促
进消化、预防缺铁性贫血、预防心脑血管疾病。醋的威力不小吧~不信你自己慢慢去发现。
其实,我们身边处处有科学,一声雷响、一个玩具、一瓶药水都能体现出种种科学原理。所以,我们一定要学好科学知识,运用科学知识来改善我们的生活。

榆林高新一小 五年级一班 韩兆媛
你看见过在花丛中自由自在飞行的蜜蜂吗?你观察过在地上爬来爬去的蚂蚁吗?这些事物在大自然中是随处可见的,只要你留心观 察,就会发现奥妙无处不在。
蜜蜂是一种昆虫,别看它长得小巧玲珑,它还拥有勤劳的美德。蜜蜂每天为了酿造蜂蜜,要辛苦飞行十几万公里。若一只蜜蜂找到蜂源的具体位置,其他同伴便一拥而上,在蜂源里默默无闻地采蜜,把爱无私的奉献给人类,这是壮举啊,值得敬仰!它告诉我们:昆虫和人类一样,只要团结合作,真情付出,就会有丰厚的回报。
蚂蚁是我们熟悉的动物,在它们身边有许多趣事发生呢!我们常常看到成群结队的蚂蚁在走动,它们看似身材细小,经不起任何雨打风吹,只能搬动像沙粒一般大的食物,其实往往会创造奇迹。 六月的天就像孩子的脸,说变就变,早上还是晴空万里,一到下午,天气阴沉沉,闷热闷热的。我走出家门,突然发现在一个墙角下,一群蚂蚁在忙碌着什么。仔细一看,哦,原来它们在搬家呢。几只蚂蚁用自己小小的嘴巴共同咬着一片树叶,我的好奇心越来越强,于是跟随它们走到目的地。到了目的地,它们轻轻地把树叶放下,然后按照相同的方法继续搬动其他食物。当大雨降临时,它们已经住在自己温暖舒适的家了。“人心齐,泰山移。”这句话的含义不正是这样吗? 这次观察让我受益匪浅,大自然对我们的启示实在太多了,只要你用心体会,就会对生物有更深层次的理解。 指导老师:苗艳

这可能是由于胃里装满了食物~肚子饱胀~在重力的作用下运动时剧烈震荡~牵扯了肠系膜~发生恶心、呕吐、腹痛的症状。所以运动前不要大量喝水~饭后不要马上进行剧烈运动~应该在饭后一个小时再运动。老师的一番讲解~让我终生受益匪浅。我懂得了~活动时~特别是参加比较剧烈的运动或比赛~身体要消耗大量的水分和营养物质~需要适时地得到适量的补充~才不致影响身体的健康。喔~原来运动时~在“吃喝”上还有这样大的学问哩。
我谨遵这样的教诲~加上大的活动量~才练就了一个好身体。看似微不足道的玩耍嬉戏之中~都蕴藏着科学知识啊~多得些知识绝不是坏事。“流水不腐~户枢不蠹。”~人人都要多运动。,指导教师 贾智君,

小学数学综合实践活动课的生命
---创新能力的培养
培养学生创新能力是知识经济时代对每一个教师发出的呼唤,也是当今数学综合实践活动课的生命。因此,在数学综合实践活动中必须渗透创新意识,着力培养学生的创造性思维,落实、加强创新教育。在实践中,我们进行了一些尝试和探索。
一、激发学生的创新兴趣
在教学中,我经常鼓励学生畅所欲言,大胆探索,标新立异,引发学生的创新活动,并及时捕捉学生的“智慧火花”与“灵感”对他们敢于创新的举动加以表扬、肯定,使学生养成敢于探索、敢于开拓,勇于实践的精神。
创新意识是一种发现问题,积极探求的心里趋向。为了激发他们的创新兴趣,我们常在新课引入时用游戏、故事、图片、试验等激发学生的好奇心,这样极大地激活了他们求知的欲望与创新的兴趣,同学们个个情趣高涨,收到了事半功倍的效果。
二、创设探究内容,培养学生观察能力。
教学成功与否,学习效果如何,取决于学生对学习有效参与的程度。眼睛是思维的窗口,“看”是获得知识的必要前提。教学中教师可以根据教学内容的需要,给学生创设充分观察的机会,引导学生主动探索知识的形成过程,感受学数学的趣味和作用,体验数学的魅力,使教学过程成为师生充满快乐、涌动生命活力的生活世界。例如,教学“什么是周长”这一课时,我就地fast boat. "Moon Pro Power pole and offshore to quickly open bow. See trailing people around the Lake called "shake up, us a lift boat!......" Shen Yuezhen stood in the bow, holding a small pistol, briskly humming "Bella Ciao". Person she wanted to send guns to the Jiangsu Taihu anti-Japanese volunteer station, look for a long time never met rade ... ... (13) Qian Guibao intensive care wounded soldiers during the war, Zhu Xi Yao bang Tao Yuan San Min, based in this village, where good mass base. In May 1939, Zhu Xi transfer 9 wounded guerrilla, Yao bang due to injury. Qian Guibao, consciously take on the task of caring for the wounded villagers, they are wounded daily diet, taken care of. A few days later, 3 injured from wounds, medical treatment failed, died. Qian Guibao, arranged to buy the coffin, washing the bodies, buried on the spot. After 10 days, the remaining number of wounded was ordered to transfer to other places. Qian Guibao, villagers ' enthusiasm to take care of the wounded, reflect the people's support of anti-Japanese patriotism. (14) mountain Bao Dai Xiuchang, eager to help the underground resistance movement in May 1939, the party member Zhuang Shaozhen according to instructions, came to the Tomb area car dam the resistance movement. He organized the Wujiang administrative team, run evening classes, to introduce youth to turn, the army's case against Japan, revolutionary Outlook on life education; by teaching the Feng Yang, the nation, said song, the sword marches such as songs and organize cultural tours and other activities, mobilize the masses, unite against Japan. Scope of activities in the joy Temple works, Miao and Hui
取材,在操场上捡了一片榕树叶给学生看,边让学生细心观察边问:“叶子的边是怎样的,”当学生回答:“有一些小齿”时,我就接着说:“你能把它的所有小齿不重复地摸一遍吗,”学生说:“行~”我就让学生摸一遍。接着让学生认真观察多媒体演示,沿着树叶的边线,一笔描出树叶轮廓的情形:第一次描是正确的,第二次描是少描一些的,第三次描是多描一些的。要求学生观察后,作出判断,并说明理由。结果学生通过观察和对比,结合自己实际摸树叶边线的轮廓,懂得了要先确定描的起点,最后要回到起点(终点),这样描才不会多描,也不会少描,初步体会了有关“周长”的内涵,接着我让学生在身边找一些物体摸一摸它们的边线,再一次领悟周长的含义,最后我让学生把物体按在练习本上一笔画出它的边线。这样做,不仅把生活问题提炼成了数学问题,开拓了教学资源,同时也使他们体会数学就在身边,培养了学生的学习兴趣,激活了学生的思维,提高了学生的观察能力。
三、创设思考机会,体验成功的喜悦。
教学中最重要的是让学生有思考的机会,要尽量让学生去发现一些问题,研究一些问题,讨论一些问题,感悟一些问题,使学生在解决问题的过程中体会“我能行,我快乐”的感觉,体会成功的喜悦。在学习完“千克、克、吨”的知识后,我让学生思考这样一道题:一架天平配有3个10克的砝码。想一想怎样才能知道多少粒花生约重50克。这道题目学生在日常生活也许有fast boat.

A few days later, 3 injured from wounds, medical treatment failed, died. Qian Guibao, arranged to buy the coffin, washing the bodies, buried on the spot. After 10 days, the remaining number of wounded was ordered to transfer to other places. Qian Guibao, villagers ' enthusiasm to take care of the wounded, reflect the people's support of anti-Japanese patriotism. (14) mountain Bao Dai Xiuchang, eager to help the underground resistance movement in May 1939, the party member Zhuang Shaozhen according to instructions, came to the Tomb area car dam the resistance movement. He organized the Wujiang administrative team, run evening classes, to introduce youth to turn, the army's case against Japan, revolutionary Outlook on life education; by teaching the Feng Yang, the nation, said song, the sword marches such as songs and organize cultural tours and other activities, mobilize the masses, unite against Japan.

经历过,是一道既普通又平凡的题目,较紧贴生活。经过学生的认真思考,不少学生写出了解决这个问题的方法。例如:(1)1次称10克,称5次。只要数一数第一次称的花生有多少粒,再乘5就知道了。(2)先称2次,每次称20克,再称10克,合起来就是50克。(3)先称30克,再称20克,合起来也是50克,再数一数有多少粒。最后我给学生提供了题目里所提到的工具及材料,让学生实际称一称,验证他们的设想。学生根据题目的信息,运用所学的知识,解决了身边的问题,并通过自己的实践验证结果,感受到了思考的快乐,成功的快乐,课堂生活的快乐,同时对学习数学也充满兴趣~
四、引导学生自主探究和创新能力
在数学活动中,学生通过动手动脑自主探索、大胆猜想、合作交流、实验验证、积极思考等方式学习数学、运用数学,更有利于他们创新能力的培养。在教学:“一位数除三位数(商是三位数的除法)”后,学生在解答这道题目:班上开联欢会,同学们布置教室,按照下面的顺序挂气球。“蓝黄黄红红红红蓝黄黄红红红红??”,买了48个红气球,要买几个蓝气球,几个黄气球,要求学生利用自己手中的学具,小组摆一摆,探索有多少种解法。学生马上动手摆学具。有的摆圆片,有的摆小棒,争先恐后地操作起来。操作了片刻,学生热烈地讨论着,有的说可列式为48?4,12(组),(蓝气球)12×1,12(个),(黄气球)12×2,24(个);有的说在一组气球里:红气球是蓝气球的4倍,fast boat.

(13) Qian Guibao intensive care wounded soldiers during the war, Zhu Xi Yao bang Tao Yuan San Min, based in this village, where good mass base. In May 1939, Zhu Xi transfer 9 wounded guerrilla, Yao bang due to injury. Qian Guibao, consciously take on the task of caring for the wounded villagers, they are wounded daily diet, taken care of. A few days later, 3 injured from wounds, medical treatment failed, died. Qian Guibao, arranged to buy the coffin, washing the bodies, buried on the spot. After 10 days, the remaining number of wounded was ordered to transfer to other places. Qian Guibao, villagers ' enthusiasm to take care of the wounded, reflect the people's support of anti-Japanese patriotism. (14) mountain Bao Dai Xiuchang, eager to help the underground resistance movement in May 1939, the party member Zhuang Shaozhen according to instructions, came to the Tomb area car dam the resistance movement. He organized the Wujiang administrative team, run evening classes, to introduce youth to turn, the army's case against Japan, revolutionary Outlook on life education; by teaching the Feng Yang, the nation, said song, the sword marches such as songs and organize cultural tours and other activities, mobilize the masses, unite against Japan. Scope of activities in the joy Temple works, Miao and Hui
求蓝气球列式为:48?4,12(个),而红气球是黄气球的2倍,求黄气球:48?2,24(个);有的说:每组气球中,红气球是蓝气球的4倍,而黄气球是蓝气球的2倍,因此先求蓝气球的个数,再乘2就求出黄气球的个数,即:48?4,12(个),12×2,24(个)。学生通过自主探究后,结合自己的思考,想出了这么多合情合理的、富有创造性的方法,我为他们的精彩回答拍手叫好,学生们也因此兴奋不已,掌声和表扬声在课堂上响了一次又一次,师生都沉浸在操作活动、发现规律的体验和乐趣之中。这样教学,使学生有成功的体验,开放了课堂,形成张扬学生个性的气氛,展示出学生不同的体验。
五、精心设计,优化练习,主动创新。
练习是一种有目的、有指导、有组织的学习活动,是学生掌握知识形成技能与技巧的基本途径,在小学数学教学中占有重要的地位。优化练习要处理好质与量、新与旧、难与易的关系。也就是说在设计练习题时,要注重练习题的质量,要设计一些有一定坡度和难度的题目,即要考虑旧知识的巩固,又考虑到新知识的铺垫,难易有度。特别要设计一些有创新的练习,让学生在练习中主动创新。优化练习,就是练习要灵活多样,有趣味性。学生在练习时要有宽松的氛围、愉快的情绪,这样,学生乐学、乐练。练习要有层次性,要由浅入深、循序渐进。同时,要有利于激发学生的创造思维的火花。还可以设计一些实践和操作的练习,如:在教完“圆柱体”的体积计算公式时,下课之前,我向fast boat. "Moon Pro Power pole and offshore to quickly open bow. See trailing people around the Lake called "shake up, us a lift boat!......"

A few days later, 3 injured from wounds, medical treatment failed, died. Qian Guibao, arranged to buy the coffin, washing the bodies, buried on the spot. After 10 days, the remaining number of wounded was ordered to transfer to other places. Qian Guibao, villagers ' enthusiasm to take care of the wounded, reflect the people's support of anti-Japanese patriotism. (14) mountain Bao Dai Xiuchang, eager to help the underground resistance movement in May 1939, the party member Zhuang Shaozhen according to instructions, came to the Tomb area car dam the resistance movement. He organized the Wujiang administrative team, run evening classes, to introduce youth to turn, the army's case against Japan, revolutionary Outlook on life education; by teaching the Feng Yang, the nation, said song, the sword marches such as songs and organize cultural tours and other activities, mobilize the masses, unite against Japan. Scope of activities in the joy Temple works, Miao and Hui
学生布置了作业:“我们已经学了长方休、立方体、圆柱、圆锥的体积计算公式,这些图形都是规则图形,那对于一个不规则图形(如一块石头),它的体积怎样来求呢,课后请同学们去研究一下,可以请教别人,也可以查资料,明天数学课上,展示、汇报成果”。再便如:在教学长方体、正方体表面积之后,我让学生在课外用纸板制作一个长10厘米,宽8厘米,高5厘米的纸盒。而且要让学生思考:怎样剪、怎样粘可以制成一个符合要求的长方体,让学生通过动手制作,明白要做一个标准的长方体,必须在适当的边上留出适当的空白粘边,否则无法粘上去。这些教学改变了“耳听口说”的简单化学习模式,让学生多种感官参与学习,使学生能进一步理解和接受知识。在练习中,让学生主动去创新,这对培养学生的实践能力和创新精神,能起到积极的作用。
六、 联系生活,拓宽创新空间
数学知识源于生活,生活中处处有数学、在教学中,我们要根据需要补充一些生活中的数学活动,拓宽学生创新的空间。学校要进行校园建设,决定对校园进行改造,修建花坛。针对这种情况,我抓住时机,向学生提出活动研究课题:“校长决定向全校师生征集花坛的设计方案,请同学们帮学校设计一下。同时想一想,建花坛需要考虑哪些问题,怎样解决,”对学生而言,这是一个比较大的综合性问题,其中蕴含了许多的数学问题,需要调动多方面的知识储备并需要结合学生实际,从不同角度考虑。fast boat.

整个活动分为三个层次:一是考虑花坛的布局、形状 、大小等因素初步确定设计方案;二是研究各种用料用费问题;三是结合学校实际选择花草品种。由于活动内容的生活化,学生纷纷走出教室,跑到操场上,比划、测量,自觉将数学知识与生活联系起来。
孩子的潜能是巨大的,重在教师的开发、引导,有创新才有进步,有创新才有发展,有创新才有实力,有创新才能腾飞。在数学综合实践活动中,我们要尽一切努力激发学生的创新兴趣,创新自己的教学理念,多鼓励、多呵护他们,珍惜学生的奇思意想,发挥好教师的主导和学生的主体作用;让数学综合实践活动课成为学生创新的源泉。

◎胡萝卜炖煮营养高
胡萝卜中主要营养素β-胡萝卜素存在于胡萝卜的细胞壁中。细胞壁是由纤维素构成,使人体无法直接消化,只有切碎、煮熟,使细胞壁破碎来释放β-胡萝卜素。所以,最好用足量的油炒胡萝卜块或与肉同在高压锅中炖煮。
◎摇头晃脑对付麻木
中老年人的手臂麻木,多由颈椎部的骨节增生引起。经常进行颈部活动,摇头晃脑,便可缓解手臂麻木。做法:坐位或站位,颈部先左、右转动几圈,低头、抬头活动几下,再左右晃动几下。动作要轻、慢,晃动次数应少些。
◎水果不能替代蔬菜
多数水果所含的维生素、矿物质和铁,比浅色蔬菜含量少,而浅色蔬菜相比绿、黄色蔬菜更是少很多。人体的许多重要生理功能必须依靠丰富的维生素和矿物质来维持,水果不能满足人体的需要,所以吃蔬菜是必不可少的。
◎洗涤剂不应该混用
洗涤剂各有配方和用途。为了增强去污效果,有人将洗涤剂混用。其实,这样极易引起化学反应而产生有毒物质,如氯气,有毒物质可使人眼、鼻、喉不适,严重的可伤人心肺,甚至危及生命。所以洗涤剂应根据用途分别使用。
◎白酒最好加热后喝
白酒的主要成分是乙醇(酒精),除此以外,就是还含醛。醛虽不是白酒的主要成分,但其对人体的损害比酒精大很多。醛的沸点只有20摄氏度左右,所以把白酒烫热一下,就可以使大部分的醛挥发掉,减少对人体的危害。
◎毛巾应该经常消毒
毛巾上会有很多致病微生物,所以应该经常消毒。健康人的毛巾可用开水煮或放在微波炉中消毒。病人使用的毛巾,可以放在高压锅内,加热保持30分钟左右或在专用消毒剂中浸泡足量时间后,用清水漂洗干净,晾干即可。

生活处处有学问
山西省运城市搏力作文 张钧玮
一天下午,我在玩电脑。电脑突然黑屏了。我搞不懂为什么,就又把电脑打开了,打开电脑后,我发现电脑什么也没变,明天我要探索电脑为什么要黑屏。
第二天放学回家,我把书包一放下,就去电脑室,迅速地把电脑打开,先把360杀毒软件打开,查看有没有病毒,没有病毒。然后我打开互联网看看有没有陌生网站,没有陌生网站呀,不可能黑屏的。最后,我发现微信不见了,我又查看c盘里还有没有微信,有微信呀~它不可能在桌面上凭空消失,难道有隐形病毒,会把你常用的软件从桌面上“拿走”,然后又模仿你常用的软件,我再次打开360杀毒软件仔细的检查有没有病毒,没有病毒,我长出了一口气。
正想着,爸爸回来了,我把“黑屏”事件给爸爸从头到尾说了一遍。爸爸笑了笑,说:“之所以‘黑屏’是因为每次用电脑时间不能超过三十分钟,微信不在桌面上是因为桌面上的软件太多,所以我把微信放到了C盘里。”
原来是这样啊~我明白了:做一件事要细心观察,善于发现,才有可能成功 。
