三年级上册数学单元知识点知识点：1、把一个物体或一个图形平均分成几份，取其中的几份，就是这个物体或图形的几分之几。

2、把一个整体平均分得的份数越多，它的每一份所表示的数就越小。

3、①分子相同，分母小的分数反而大，分母大的分数反而小。

②分母相同，分子大的分数就大，分子小的分数就小。

4、①相同分母的分数相加、减：分母不变，只和分子相加、减。

②1与分数相减：1可以看作是分子分母相同的分数。

练习题：一、填空题。

1、把一块月饼平均分成2份，每份是这块月饼的一半，也就是它的()分之()，写作(—)。

2、把正方形纸平均分成4份，每份是这个正方形的()分之()，写作(—)。

3、把1分米平均分成10份，每份是1分米的()分之()，写作(—)。

3份是它的(—)。

4、2/5是把一张纸平均分成()份，表示这样的()份。

3/5是把一张纸平均分成()份，表示这样的()份。

2/5和3/5都是把同样的一张纸平均分成了5份，这样的2份显然比3份()，所以2/53/5。

同样道理，5/6比2/6()。

5、4/5里有()个1/5，2/3里有()个1/3。

6、7个1/10是(—)，4个1/7是(—)。

7、1/8是1个八分之一，2/8是2个八分之一，1/8+2/8也就是1个1/8加上2个1/8，一共是3个1/8，也就是(—)。

教师招聘考试题库《教育理论综合知识》考点强化练习最新版(二)1、单选题材料题请点击右侧查看材料问题_____A : 高智能型B : 高创造型C : 场依存型D : 场独立型参考答案: C本题解释:参考答案：C。

参考解析：所谓场，就是环境，心理学家把外界环境描述为一个场。

美国心理学家赫尔曼? 威特金认为，有些人知觉时较多地受他所看到的环境信息的影响，有些人则较多地受身体内部线索的影响。

这种倾向于利用外在参照作为信息加工的依据的认知方式，即场依存型；倾向于更多地利用内在参照作为信息加工的依据的认知方式，即场独立型。

f12的请求参数F12的请求参数是指在浏览器中使用开发者工具（F12）查看网络请求时，所包含的参数信息。

通过查看F12中的请求参数，我们可以获取发送请求时所需要的请求头、请求方法、请求地址等相关信息，帮助开发者进行网络调试和接口调用。

在F12中，我们可以通过以下步骤查看请求参数：1. 打开网页并进入需要调试的页面。

2. 按下键盘上的F12键，或在浏览器的菜单中选择开发者工具（通常位于菜单的“更多工具”或“开发人员选项”中）打开开发者工具面板。

3. 在开发者工具面板中，切换到“网络”（Network）选项卡。

这里会显示页面发送的所有网络请求。

4. 选择其中一个请求，点击该请求展开，即可查看该请求的详细信息。

5. 在该请求的详细信息页中，可以查看请求的一些基本信息，如请求地址、请求方法、请求头等。

6. 进一步展开请求的详细信息，我们可以查看请求的参数。

请求参数通常会显示在“Headers”（头部）或“Query String Parameters”（查询字符串参数）中，根据请求类型的不同可能会有所区别。

了解F12的请求参数对于开发者来说非常重要，因为它可以帮助我们了解接口调用中所使用的参数，以及检查参数是否正确、是否完整。

通过查看请求参数，我们可以确认请求是否按照预期进行，从而进行调试或修复代码中的问题。

在实际开发中，F12的请求参数还可以帮助我们分析接口的具体实现和设计，以便更好地理解和使用接口。

同时，通过查看其他请求信息，如响应状态、响应头等，我们还可以深入了解接口的返回数据和处理过程，便于调试和优化页面加载速度。

总之，F12的请求参数是开发者用于网络调试和接口调用的重要工具之一。

通过查看请求参数，我们可以获取发送请求所需的关键信息，帮助我们进行开发和调试工作。

人教PEP版人教版有哪些区别内容明显不同其次出版单位也明显不同。

人教PEP是人民教育出版社出版的一种英语考试教材。

这样的考试教材是供三年级开始用的。

PEP是初等的、小学英语的学生书。

也可说人教PEP版是人教版的一个分支。

人教版是由人民教育出版社出版，简称为人教版。

小学到高中都拥有这个版本的考试教材。

也是大多数学校所用的考试教材。

“人教版”大多数情况下是就教科书意义来说的是对比其他出版社出版的教科书来说的。

例如我们国内中小学教育辅导报刊中，《语文报》《中学生学习报》《学苑新报》等均有着不一样版本的教学辅导报纸，诸如人教大纲版、人教新课标版等。

这两个版本名称均是配合由人民教育出版社出版的教科书的报纸是新课改前后的版本名称。

随着新课改的深入，前者渐渐退出历史舞台，后者便统一称为人教版。

小学四年级数学学习方法1、加强整数和小数计算练习计算能力要过关。

四年级整数计算和小数计算必须非常熟练，保证准确率和速度，不然到了五年级就要重点学习分数，整数还不够熟练，到时面临的压力会更大。

建议每天坚持就5道计算题，提高做题速度和准确率。

2、培养孩子良好的学习习惯四年级是学习习惯养成的好时间，及时养成好的习惯更有利于后期的学习。

具体包括：a、课前做好预习，课后及时复习。

课前预习，了解所要讲的知识点，带着问题来听课效果会更好。

所有的知识点是不可能在有限的课堂时间去完全掌握住的，家长要督促孩子做好课后复习，及时巩固所学知识点。

b、规范孩子的书写。

随着应用题的增多，一定要规范孩子的书写，对步骤过程要到位，对于行程要养成画图的习惯，数论要思路严谨，书写规范。

c、养成独立思考和勇于思考的习惯。

孩子现在最欠缺的就是独立思考，依赖性较强，畏难情绪较重，遇到问题就退缩，这时要多鼓励孩子自己思考，养成爱思考的习惯。

二年级孩子怎么学习英语1在生活中学英语如果你自己会说英语的话，你可以在生活中用英语和孩子交流。

在生活中学习英语，就无所谓“是不是感兴趣”，而是在真实环境中感受英语、运用英语。

对于低龄儿童来说，是最自然的语言学习方法。

2用一些原版幼儿卡通片如果你自己不会说英语，可以给她买一些动画片，比如《迪士尼神奇英语(Dysney Magic English)》、《天线宝宝(英语版)》、《粉红猪小妹》。

这些视频，也许孩子不能理解全部语言，但是因为情节生动，孩子能够在无意识中接受一些语言。

但是这种学习方式的效率不高，因为孩子通常不会跟着说。

这也是人之常情，你的看电影的时候，也不可能跟着说的，欣赏就是欣赏，哪里还有时间跟着说呢?所以，在播放这些内容的时候，你要陪着看，然后利用暂停功能，让孩子在第二遍的时候跟着说。

3运用儿童英语教学视频还有一些视频是教学类的，比如《三只小猪》、《洪恩GOGO学英语》、《猫和老鼠》(英语学习版)等，视频当中就是有安排停顿、反复、提问，以便孩子跟读、回答等。

4参加培训班如果有比较好的儿童英语培训班，相对来说比较系统,也可以参加。

教师还会安排游戏活动、会话活动等。

5暂时不要有书写的内容对于低年级的孩子来说，还不需要安排书写的内容，否则会增加学习的负担。

6需要加入直拼法的训练如果想做一些阅读训练的话，建议加入与直拼法(phonics)有关的绘本阅读。

二年级学生学习英语的秘诀1.兴趣培养不等于孩子高兴判断兴趣培养的最基本标准：合理地引导孩子获得成就感。

少儿英语课堂，经常见到老师给孩子口头鼓励?Good.、加分、小礼物。

这些绝不是简单的?讨好?行为，而是，让孩子牢记下面的两点： 1)什么是好的学习习惯(比如，努力跟随老师的要求 = 培养注意力) 2)英语学习的重点是什么(比如，老师问，How many apples are there in the picture? 孩子努力用句子回答，There are four.)2.拼读单词不等于英语只学了单词一句话里，可以只有1~3个单词。

部编版和人教版的区别编写单位不同。

就如上面所说，部编版是由教育部组织编写的。

而人教版的教材则是由人民教育出版社出版的教科学。

人教版是按照出版社来说的，只要是由人民教育出版社出版的就是人教版的，并不是说由人民教育出版社撰写的。

古诗文比重不同。

相对人教版的教材而言，部编版教材在古诗文的占比更多。

就整个小学6个年级12册教材书中共选入优秀古诗文124篇，占所有选篇的30%。

初中古诗文选篇也是124篇，占所有选篇的51.7%。

部编版相对人教版课外知识更多一些。

部编版教材这样做的是为了避免精讲文章过多而降低学生的阅读兴趣。

课外阅读延伸，可以增加学生的知识储备量。

让“教读”、“自读”和“课外阅读”三者结合起来。

部编版更注重基础知识的学习。

以小学教材为例，无论从认字还是写字的个数上来说，部编版都比人教版的要求有了明显的提升。

比如：部编版增加了文字笔划的教学。

部编版更适合现代的教学模式。

无论是在教材课文选取、习题设计，还是在课后作业等方面都力图贴近当代中小学生的“语文生活”。

教材封面上有明显的标识，以区别教材是部编版，还是人教版。

关于认字与写字的要求新的部编教材和原来的人教版相比，更加注重基础的掌握与积累。

其中对小学生而言最重要的认字和写字要求，新编的部编版教材就对孩子就提出了更高与更细致的要求。

课文语言表述全新的不编教材不光从基础要求上有所增加，还将以前课文原文出现的问题进行了细致入微的修改。

让文章表述语言应用更加得体规范。

课后作业要求最新的部编版教材对孩子的课后作业要求有了更加细致明确的指导，将原来操作性不强的要求全部转化为明确的指示，更符合儿童的发展要求。

纠正了原来教材中不合理的语言表述应当说新教材还是注意“接地气”的。

银子的鉴别方法以下是小编生活百科频道编辑为您整理的银子的鉴别方法，供您参考，更多详细内容请点击小编()查看。

鉴别白银真假的方法：1.颜色判断颜色判断又可以有两种方法。

一种是火烧法。

如是真白银，经火烧烤后银色不变;若是假白银，或是低劣品，烧烤后则会变黑。

另一种方法是硝酸测试法。

在银饰品表面滴几滴硝酸，一会儿后抹去，如果饰品表面仍是银白色，这说明含银量相当高;若是银含量低的饰品，则会呈灰黑色。

2.声响判断由于白银比较柔软，如果抛落在坚硬物体上，发出的声响是疲软的;如果是其他金属，则发出清脆的声响。

3.比重判断白银的比重为10.5，比其他金属或合金都大得多。

4.折弯法用双手折弯，如果是成色高的，易弯不易断;如果是质次的，折弯时则感觉较硬，或只能勉强折动;有的甚至无法折动。

包银的，经折弯或用锤子敲几下会裂开，假的就经不起折弯，易断裂。

5.看茬口测试把银饰品横向剪断一半，观察看颜色。

如若口雪白而绵，成色在98%左右;若口粗而柔，稍带微红，成色在95%左右，用手弯折较硬;若口白而带灰，或略有微红，成色在95%左右，硬度较大;若口淡红色，黄中带灰色者，成色在80%左右，弯折坚硬;若口微红、微黄、土黄等色，成色在70%左右;若口红中带黑，黄中带黑，成色在60%左右。

6.银药抹试银药，又名吃银虎，是用95%以上成色的白银面和水银调和而成的软体状物。

将银饰品在试金石上磨出银道后，在银道上涂抹银药。

成色越高，挂银药越多，假的则完全不挂银药。

纯银又称纹银，目前现有的科学能够提炼的最高纯度为99.999%以上，纯银一般是作为国家金库的储备物，所以纯银的成色一般不应低于99.6%。

而低于这个级别的，含量大于等于99%的白银，我们称作为足银。

一般材质较软，不适合做成饰品。

色银又称普通首饰银或次银。

在纯银或足银中加入少量的其他金属，一般是加入物理化学性质与银相近的铜元素，就可以形成质地比较坚硬的色银。

色银富有韧性，并保持了纯银的延展性，同时可以减低空气对银的氧化作用，因此，色银首饰的表面色泽较之纯银与足银更不易改变。
