+ 加入清单生物都具有一个共性,那就是生命。
我家养了一只可爱而有趣的小猫,它的活动可灵敏了。
有一次,妈妈从菜市场买了一条我最爱吃的草鱼。可是,在妈妈准备调料一眨眼的工夫,盘子里鲜嫩的鱼就被猫偷走了。妈妈发现了,拿出钢尺一边追一边打,小猫“喵喵”地叫,好像在说:“我错了,别再打我了。”
我吃饭的时候,经常把吃剩下的鱼骨喂它吃。有一天,我还照样给它鱼骨吃,它却不吃了,还“喵喵”地叫起来,好像在说:“换点新花样吧!”我只好给它喂些剩菜吃,结果,它却津津有味地吃起来。
我经常用毛线团逗它玩,它生气的时候,经常会把自己锁在笼子里,耷拉着尾巴,好像在说:“没人跟我玩,真伤心。”我和这只小花猫一起生活了好几年,产生了深厚的感情,它给我的生活带来了无穷的乐趣。

strong man can enjoy the pleasure of life.
Secondly, happiness consists in contentment. A man who is dissatisfied with
his present condition is always in distress.

+ 加入清单“让”,是中华民族的传统美德。“让”,不仅仅是对个人的要求,更是对社会的要求,这个社会也因“让”而更和谐美丽。
“奶奶,车子还有多久才到呀?”稚嫩的童声传来,原来是一位三四岁大的小娃娃。她身旁站着一位年过花甲的老人,老人笑着说:“小囡乖,再等一下。”老人嘴上这样说,心里却不免担忧。正巧,公交车来了,老人刷了卡,牵着小孩的手上去。“小囡,快去找个位子坐着吧!”奶奶说道。小囡穿过人群着急地找着座位,回头有些失落地对奶奶说:“奶奶,位子没有了,可是我好累啊,我想坐着。”奶奶闻言,一脸心疼地看向孙女:“小囡,我们去问一问别人可不可以让个座。”
小囡来到一位中年妇女面前,带着期待的神情问道:“阿姨,您能让个座吗?”妇女不耐烦地看了看眼前的孩子说:“没看到我拎着这么多东西吗?哪有什么位子让给你啊?”小囡的大眼睛闪了闪,似乎在说没事,再问一问别人。她又想去问旁边的叔叔,还没等她开口,叔叔就先说话了:“哪来的小屁孩?走走走,没空理你。”小囡再次受到拒绝,她备加受挫,闷闷不乐地去找奶奶,扯着奶奶的衣角说:“奶奶,我还是不坐了吧!他们都不让座。”奶奶皱了皱眉,深呼一口气,拉着小囡的手,两人一同蹒跚地走向一位十四五岁的女孩身旁,问道:“小姑娘,你能让我们坐一下吗?我们刚刚赶路都很累了。”女孩挥挥手说道:“这位奶奶,很抱歉,我也很累,你还是去找别人吧!”
终于,小囡原本红润润的小眼睛湿润了,她忍不住哭了出来:“奶奶告诉我……做人要……懂得让……,可是……可是……呜呜呜!”在小囡的哭声中,所有人都思考着。
良久,一个清朗的声音响起了:“小孩子,你过来坐吧!”小孩和老奶奶的脸上露出了笑容,像太阳一样光芒四射。
这一次,没想到的是一位少年给大家上了一堂课,让,是每一个人都应该拥有的美好品质,我们的社会不也会因“让”而更温暖吗?
篇15:初中化学教学日记
全文共 1041 字
+ 加入清单中考仅仅只有1个月了,这个时候孩子要记要背的东西太多了,但是背会了就一定能把题做对吗?这点大家也是非常有感受的。为了让更多的孩子中考化学少失分,这里会坚持给大家总结一些中考易错题的解法与小练习。每天十分钟,轻松学化学。
今天要讲的是滤渣和滤液问题,这次四调这道题很多孩子都失分了。是孩子不会金属活动性顺序表吗?不是。那么这种类型的题怎么做呢?
解题步骤:
1。判断体系可能发生哪些反应,写出化学方程式。并依据金属活动性判断反应发生的先后。
如果题目没有更多信息,就分类讨论:
2。分恰好与其中一种物质反应,与2种都完全反应和与2中物质不完全反应三种情况来讨论。那样判断题干给出的结论对错就有章可依了。
用2012年中考最后一道选择题来验证哈把。
题目:向AgNO3溶液中加入一定质量的Al和Fe的混合粉末,充分反应后过滤,得到滤渣和浅绿色滤液。关于该滤液和滤渣有下列四种说法:
①向滤渣中加入稀盐酸,一定有气泡产生。
②向滤渣中加入稀盐酸,一定有沉淀产生。
③滤渣中一定含有Ag。
④滤液中一定含有Fe(NO3)2,一定不含AgNO3,可能含有Al(NO3)3。
以上说法正确的个数为
A。0个B。1个C。2个D。3个
解析:体系中Al,Fe均与AgNO3反应,得到浅绿色溶液则有硝酸亚铁生成。也可知滤渣中肯定有银,那么如果AgNO3过量,将Al,Fe消耗完,则1中肯定有气泡产生错误。如果AgNO3不足,则2中一定有沉淀生成错误。3正确。4关于硝酸银是否含有我们无法确定。所以4错误。答案是B
除了学会分析,平时对各类物质化学性质的积累也是关键哦,最重要要了解会发生什么反应,随之判断现象。
再给大家几道类似的练习题把。这类题考到的概率是极大的。
1.向Cu(NO3)2溶液中加入一定量的铁粉充分反应,下列情况中可能出现的是()
①溶液中有Fe2+、Cu2+、不溶物为Cu;②溶液中有Fe2+、Cu2+、不溶物为Fe;③溶液中只有Cu2+、不溶物为Fe;④溶液中只有Fe2+’不溶物为Fe、Cu。
A。①③B。①④C。②③D。③④
2。已知铜和铁都能与氯化铁溶液发生反应,反应的化学方程式如下:
Cu+2FeCl3=CuCl2+2FeCl2
Fe+2FeCl3=3FeCl2
向装有氯化铁溶液的烧杯中,加入一定量的Cu和Fe的混合粉末,充分反应后发现烧杯底部仍有少量固体,过滤。下列判断正确的是
A.滤液中一定含有CuCl2、FeCl2B。滤液中一定含有FeCl3
C.滤渣中一定含有Cu和FeD。滤渣中一定含有Cu、可能含有Fe

放假回来,清理了不少杂物,然后,感觉,好舒服好舒服

在阳台上,有着一堆烂泥紧贴着我房间也正好对着床头(想起许志安的那首歌--烂泥,大家不妨再听一下,那首歌曾经是当年的金曲,许还居然拿了最佳男歌手),烂泥上面还居然铺着一层铁网,上面堆着如下物体:一个很烂很烂的老鼠笼,10个以内的烂花盆,几块烂石,还有其他我都忘记了。清理烂泥时,居然发现里面还有很多碎瓦,更奇怪的是,里面还有好多条铁条,很幼,但比铁丝要粗韧,而奇怪的是,它门都对着我的床头,真奇怪啊(不禁想到自己自从搬到这个金菊花小区之后发生了这么多事)。
之后,我发现,对着我房间的还有一棵长的很茂盛的黄皮(白话俗称鸡屎果),听到这个名字,我就想把它砍掉,但妈妈已经种了很多年了,太大了,其实我当时也不明白,为什么盆景要种黄皮。不过,妈妈这两年还种了番薯藤,好多盆都放在窗口边,还有菲菜(白话称为九菜),至于杨桃,我觉得很难入口。
这些天搬了很多很多东西,虽然辛苦,自己身体也不好(自从搬到这个小区后,到现在好像周身都是病,斜视,肥胖,精神不佳,应该是很不佳,肾亏,疝气,最近还出现了高血压迹象,心跳很快,呼吸急速,还有以前破相所带来的的听力下降,鼻炎,怕见阳光,交际困难,混混鄂鄂,做事轮尽,个人能力严重下降,被人突然无端指着来毒骂(一个初中的杨姓同学)都居然可以无反应等等了),但搬走后,真的舒服很多,真的,真的很舒服,缠绕自己多年的破相(被妈妈捏难了鼻子,但妈妈却说,这是你自己的事情,要靠你自己去冲破这个困扰,谁也帮不了你)困扰也松了。
今天先写到这里,下次继续,再见。
篇17:初中生物教学日记
全文共 1921 字
+ 加入清单初中生物实验教学实施素质教育的目标是培养具有较高的科学素养、具有科学的思维和研究方法、具有创新意识和创新能力的人才。生物实验教学是培养学生观察能力、动手操作能力、推理分析能力和创新能力的重要途径。那次,在教学中,可以通过实验强化学生思维意识和动手操作水平,从而达到培养学生的创新和创造能力的目标。下面就一下几方面谈一下关于生物实验及创新的认识。
一、认真备课,掌握步骤和要领
教师在备课时应先做好实验,分析实验步骤。实验步骤是学生动手规范操作的要领,只有理解、掌握才能规范操作,实验才能成功。因此实验前指导学生预习,将实验步骤由繁化简,抓住每一步的关键词语串通于实验步骤之中,可以收到好的实验效果。
例如,显微镜使用过程中的“三个一”:一、安放距桌边一掌(5-7cm);二、对光要目(目镜)物(物镜)通光(通光孔、光源)一直线,光强用平面镜,光弱用凹面镜;三、观察时标本对孔正中距离物镜一厘米,视野中出现标本颜色或杂质时观察目标即将到位,微调粗旋镜升降,细旋校象清晰,找不到目标时缓缓移动玻片标本即可找到。操作时用左眼观察时,同时右眼睁开,转动物镜时,应扳动转换器。这样学生很快对好光,观察到标本在视野中的图象。用完显微镜擦干净外表。转动转换器,把物镜偏两旁,放回镜箱原处。
再如,制作临时装片的实验,将实验步骤概括为擦→滴→取→展→盖→染。然后强调注意事项。滴一滴清水,太多易外溢,太少易出现气泡。取材薄而透明透光易观察,展平防重叠,轻盖防气泡。气泡与细胞的区别,气泡呈圆形,边厚黑,中间亮白,轻压变形。这样学生很快掌握步骤、要领,在显微镜下观察到自己制作临时装片中的细胞,认识细胞壁、细胞质、细胞核(细胞膜紧贴细胞壁,在光镜下看不见),然后绘出细胞结构图。这样学生就达到了实验的目的要求,兴奋不已,终生难忘。
二、指导实验,及时反馈和调控
在实验中,教师通过巡视,随时纠正学生的操作错误,及时表扬规范操作快而且准确的学生这是实验过程中的及时反馈与调控。例如,有的学生在实验过程中,急于观察,但未按课本的有要求操作,他们或用高倍镜对光,或光圈反光镜未调好,就急于调整粗准焦螺旋,眯着眼睛看目镜。这时,教师应启发学生对照课本的操作要求,检查自己的操作错误并纠正。学生在独立进行实验操作时,往往心理负担较重,动作技能还没有熟练,出现一些错误是正常的,教师要耐心的支出并给予及时的纠正。实验结束后,对表现好的学生要及时给予表扬,对普遍存在的失误应给予分析和纠正。让学生吃一鉴,长一智。整个过程要处分发挥学生的整体作用,也要充分发挥教师的主导作用。
三、正确处理规范与创新的关系
中学生物实验大部分属于验证性实验。而要提高学生的科学素养,除了掌握课本结论外,还应提高学生的创新与探索意识。教师在实验过程城中,既要要求学生严格规范实验操作,又要引导学生的创新思维。例如,在“练习和使用显微镜”的实验中有些学生会对显微镜感兴趣,除了完成教师规定的操作外,还会放一根头发或一张纸在显微镜下观察,这种做法是对显微镜无损的,。却反映出学生的求知欲,教师不但不应制止,还应当因势利导,让学生说说实验结果,引导学去理解“所观察的材料必须是薄而透明的”。在这一实验中,一些学生会转转目镜、物镜等,此时教师可以提出“如何判断视野中的污点在哪里?”以此来培养学生的发散思维。
四、将某些验证性试验改为探究性试验
探究性试验与验证性实验相比,更能发挥学生的整体作用,克服思维定式的束缚,更有利于学生的探索精神和创造性思维的培养。因此要鼓励学生不迷信权威,大胆探索,大胆创新。例如在“验证人体呼出的气体中含有较多的二氧化碳”时,我就鼓励学生把它变成探究性实验。人体呼出的气体有二氧化碳吗?人呼出的气体有二氧化碳吗?人呼出气体中二氧化碳与空气中二氧化碳含量相同吗?提示二氧化碳能使澄清的石灰水变浑浊。在这一实验中可将打气筒变为吸耳球,考虑到学生没有使用过吸耳球,在实验前向学生出示洗耳球并简单介绍他的作用。然后学生经过讨论、分析制定了下列实验步骤:①取甲乙丙三只试管,分别注入10毫升澄清的石灰水;②用玻璃管向甲试管中吹气,重复几次,一段时间后,发现甲试管中澄清的石灰水变浑浊;③取一只玻璃管插入乙试管中,不断用吸耳球向玻璃管内压气,与向甲试管中吹气的时间相同,发现澄清的石灰水变浑浊;④以丙试管作对照,比较甲乙两支试管,发现甲试管石灰水变浑浊程度深;⑤得出结论;人呼出的气体中含有较多的二氧化碳。
实验的成功与失败都会引起学生注意,进而探索实验材料的选择等,培养了学生的思维能力、分析解决问题能力以及实验创新能力。
生物是一门以实验为基础的学科。在教学中注重实验教学,一定能使我们的教学事半功倍。

+ 加入清单As the drawing presents, there is a man walking across the street
absorbedly focusing on his cell phone without noticing the surroundings. This
sort of phenomenon is not uncommon and rare in some metropolis, especially among
the youngsters.
What the picture illustrates is the prevailing situation that has long
existed in todays China. That is the mobile phone obsession. With the advent of
information age, people are becoming
increasingly fascinated on the electronic products, especially the cell
phones. Not surprisingly, you could easily notice that most of us are obsessed
in sending messages, playing online games with their mobile phones. It cannot be
denied that this phenomenon may negatively impact the relationship among people,
and therefore they will become estranged and isolated.
Personally, in view of the overuse of mobile phones, I hold that we
individuals should raise the necessary awareness that good relationships are
reinforced by sincere and face-to-face communication.

一、组织教学、课堂导入:
同学们在学习语文的过程中感到最可怕的是写作文,感到最难的`也是写作文,胶尽脑汁而无处下笔,搜肠刮肚找不到一个恰当的词语。不由的发出感叹:“作文难啊,难于上晴天”。其实作文难写吗?答案是肯定的!真那么难写吗?亦不然!
因为在祖国的语言文字里,有黄河的不羁和刚强,有长江的奔放和潇洒,有泰山的威武,有草原的粗犷,有彩陶的古朴典雅,有花椒的芳香四溢。有先秦的繁星明月:是皎洁的汉宫秋月,是珠落玉盘的琵琶,是高山流水的琴瑟,是“推”“敲”不定的月下门,是庄子的逍遥游,是孔子的颠沛流利,是魏王的老骥之志,是诸葛的锦囊妙计,是君子好逑的《诗三百》,是魂兮归来的《楚词》,是执过羊鞭的《兵法》,是受过宫刑的《史记》,是李太白的杯中酒,是曹雪芹的梦中泪,是千古绝唱的诗词曲赋,是功垂青史的《四库全书》……它不仅是我们每个人学习、工作、生活的工具,而且负载着丰富的情感,深邃的思想,人类的文明。有了这些,我们写作文怎么会难写呢?何愁写不好呢?这就要我们平时养成多读书、读好书的习惯,写好读书笔记。因为书到用时方恨少。这节课老师和同学们一起解决作文中的一个难题:如何使作文具体化?
二、活动一:
(一) 、教师演示:教师手拿一枚硬币,硬币从手中滑落,掉到讲桌上后又掉到地上。
1、要求:
(1)、每一个同学仔细观察这种现象,然后用一句话描写这种现象。
(2)、同学之间交流、分享。
摘录例句:
(1)、有一枚硬币从老师手中滑落,掉到了地上。
(2)、有一枚硬币从老师胖乎乎的手中滑落,掉到了讲桌上,然后又像一个小精灵叮叮当当的掉到了地上,在地上画了一个优美的圆弧后平静地躺在哪儿。
2、分析:
在同学们写的句子中你认为哪一句写的最好?原因是?第二句比第一句增加了一些内容,说说增加了哪些内容?
通过讨论分析得出结论:都认为第二句好。第二句不仅写出了硬币从哪儿掉下来,更写出了老师的手,硬币掉到地上的响声,还运用拟人的手法,写出了硬币的姿态,写出了情感。
3、教师点拨:
我们在课堂上要会听课:伸开耳朵去细心的听,睁大眼睛去仔细的看,张开嘴巴去详细的说,用心去细细的想,让后用笔去写写、记记——你看看你变的“聪”明了。在前面的学习讨论中,逐步扩充,最终使句子完整、生动、形象,我们不妨给它取名“步步追问”。用这个方法可以把内容写的具体一些。但是同学们想想:在现实生活中,我们遇到的事情,能不能每件事情都要去演示,都要去追问,这显然是不可能的!有些事情我们不能去演示,只能通过联想和想象去解决,使情节更合理,我们不妨叫它“想象延伸”。如“绿色”、王羲之“之”字写法、“台阶”你可以想到什么?
4、学生讨论总结:
由“绿色”想象到:“水、植物、春天、军人、生命、和平、希望、朝气、青春……等”;
由王羲之“之”字写法想象到:“要有个性、不要墨守成规、行行出状元……等”;
有“台阶”想象到:“一切从零开始、成功的道路的不平坦的、人梯精神、永不止步……等”。这样以来我们的思维变的活跃了,视野开阔了,作文变得好写了。
5教师点拨:我们每天生活在祖国温暖的怀抱之中,生活在亲人、老师、同学的关爱之中、生活在亲情之中,其乐融融。要我们去刻画一个人物的肖像,同学们想想,上面两种方法是否可行?显然以上两种方法是不不够的,我们必须对一个人的某一部位,某个方面进行精细的描绘,才能表现出这个人的优秀品质,我们不妨叫它“局部雕刻”。举例:《范进中举》中胡屠户形象。
三、活动二:根据以上方法进行片段练习。
(一)、练习话题1:我惭愧。
1、公式:具体心理形象=步步追问+想像延伸
2、注意:
(1)、是什么原因惭愧?
(2)、惭愧时是什么表情?
(3)、惭愧时是什么心理?
3、师生互动交流,分享成果。
4、教师范文:
我惭愧。我站在老师跟前,耷拉着脑袋,脸火烧火燎的,两只手没处放了,只是无意识的拧着衣角,两脚无力的支撑着身体。心里好像打翻了五味瓶,酸甜苦辣咸,什么滋味儿都有。同学们信任我,选我当班干部,我却做出这等丢人现眼的事儿,我对的起谁?是家里的父母,还是学校里的老师。我的目光在地面上搜寻着,如果有个缝儿的话,我一定会钻进去。
(二)练习话题2:既喜欢又讨厌的同桌。
1、公式:具体人物形象=步步追问+想象延伸+局部雕刻
2、注意:
(1)喜欢到什么程度?
(2)讨厌到什么程度?
(3)为什么会有这样两重情况?
(4)特别注意人物刻画。
3、学生练笔、师生互动、交流分享成果。
4、教师范文:
1、大胆夸张,来点叛逆。
范文:
已知:数学卷2张,语文卷2张,物理、化学卷各1张,英语卷2张, 求:能否在眼皮打架之前做完?
解:因为:一天24小时,在校上课学习时间9个小时,睡觉休息时间8个小时,吃喝拉撒、路上时间2个小时,数学卷2个小时,语文卷2个小时,物理化学卷2个小时,英语卷2个小时。
所以:总共需要27个小时。 结果:在眼皮打架之前不能完成。
2、巧妙悖论,来点幽默。
范文:
3、准确扑捉,画一副漫画。
范文:
4、学以致用,历练身手。
范文:
五、总结:文似看山不喜平。所以除了引人眼球的标题,一锤定音的开头,回头百媚生的结尾外,还要做到词语生动、句式灵活、善用修辞、文体立意等诸多方面。做生活中的有心人,在生活中运用语文,在生活中学会语文。
六、作业:以“他在娘的脸上亲了一下”为话题,写150字左右的片段。
七、板书设计
