七、阅读理解：(20’)

Ａ

As we know, there are differences between western culture and Chinese culture.We can see differences when we pay attention to the way words are used.Let’s look at the words about animals and plants.Most expressions in Chinese about the dog, for example, “a homeless dog”, “a mad dog”, “a running dog” and “a dog catching a mouse”, have negative(消极的）meanings.But in western countries, dogs are thought to be honest and good friends of humans.In English, people use the dog to describe positive（积极的）actions.For example, “you are a lucky dog” means you are a lucky person.And “every dog has its day” means each person has good luck sometimes.To describe a person’s serious illness, they say “sick as a dog”.The word “dog-tired” means very tired.However, Chinese love cats very much.But in western culture, “cat” is often used to describe a woman who is cruel（冷酷的）.There are many other examples of how “cat” is used differently as well.The rose is regarded as a symbol of love in both China and some western countries.People think the rose stands for（代表）love, peace（和平）, courage and friendship.And the rose is the national flower of England, America and many other countries.The words about plants and animals are used in positive or negative ways in different cultures.We can learn about many differences in cultures by comparing(比较)how some words are used.()1.The word “dog” in Chinese usually _______.A.shows peaceB.stands for friendship C.has a negative meaningD.has a positive meaning()2.“Every dog has its day.” means “_______”.A.If one works hard, he’s sure to succeed.B.Everybody in the world is lucky.C.Each person lives his own way of life.D.Everybody has a time in life to be lucky.()3.Western people usually use “cat” to refer to(指代)“_______”.A.a tired personB.a brave manC.a homeless personD.an unkind woman()4.Which of the following is true according to the passage?

篇2：单元整组观照下的课堂练习设计

一、形成单元整组练习体系

一组课文的课堂练习, 应该有一个向心点、一根指挥棒, 使每篇课文的练习有机地、系统地融合起来, 这根指挥“单元整组”课堂练习的指挥棒, 就是单元整组课堂练习总目标。单元整组课堂练习总目标使每单元之间的课堂练习能紧紧围绕这个总目标展开, 形成练习体系。那么《搭石》一课所在的四上第六组课堂练习总目标是如何定位呢?

1.紧扣课标, 基于学段整体目标。从第二学段“阅读目标”去思考:阅读目标并没有自然段教学的要求, 但是根据学生语言学习和能力发展的需要, 我们认为第二学段的自然段教学十分重要, 它是介于词句教学和篇章教学的过渡环节, 对学生概括能力的培养和表达能力的发展都很重要。而第二学段文本中的许多自然段, 其实是由一幅幅的画面组合而成的, 因此这一阶段的自然段教学更多的是画面教学。

从第二学段“习作目标”去思考:第二学段课标习作目标中有这样的要求“能不拘形式地写下自己的见闻、感受和想象, 注意把自己觉得新奇有趣或印象最深、最受感动的内容写清楚”, 这里的“见闻”“想象”和“自己觉得新奇有趣或印象最深、最受感动的内容”, 其实更多的是学生观察捕捉到的画面, 因而这一阶段的习作教学更多的应是让学生写好一个或几个画面。

2.细读教材, 着眼整组文本特色。四上第六组教材编排了《搭石》《跨越海峡的生命桥》《卡罗纳》等五篇课文, 还有一个语文园地。细读整组教材, 你会发现五篇课文是由一个个画面组合而成的, 语文园地“习作”是看图作文, 重点要达成的是对画面的想象和描写。

3.单元整组, 集成系统练习体系。基于以上学段整体目标和整组文本特色的思考, 我们把四上第六组单元整组的练习总目标定为:学习不同的写画面的方法, 并尝试运用。在这一“单元整组”课堂练习总目标下, 再制定单篇课文的课堂练习核心目标:《古诗两首》——想象画面, 积累用寄托情感的事物写画面的诗词;《搭石》——学习运用关联词有序表达的方法写画面;《跨越海峡的生命桥》——学习在同一时间写画面的方法;《卡罗纳》——学习运用人物言行、神情写画面的方法;《给予是快乐的》——学习运用人物言行、神情写画面的方法;《语文园地·习作》——试着运用本组写画面的方法把画面写具体。

二、切准单篇练习核心目标

《搭石》课堂练习核心目标:学习运用关联词有序表达的方法写画面, 又是怎样定位的呢?

1.紧扣课程, 发现特质, 提升素养。细读《搭石》我们发现, 这篇课文的自然段以承接式段落为主, 表达十分有序, 而第二学段教学重点是自然段教学, 学生更多的应该学习自然段连句成段的方法, 另外有序表达又是第二学段习作教学的重点。再加上, 由于目前仍未真正走出内容分析式的阅读教学, 一些时候我们会更侧重于自然段“言之有物”方面的课堂练习, 而不同程度忽略了“言之有序”的练习。因此, 《搭石》课堂练习的重点应该是让学生学习有序表达, 而不仅仅是感受家乡人的心灵美。

2.发现秘妙, 立足语言, 习得能力。《搭石》语言表达富有条理性, 尤其是第2自然段和第4自然段, 运用了“无论”“只要……一定……”“直到……才……”“如果……总会……”等关联词有序描写了“换搭石”和“让搭石”两个画面, 而“帮老人过搭石”的画面, 作者一笔带过, 没有充分展开。因此, 在确定练习核心目标的时候, 提出了“学习运用关联词有序表达的方法写画面”的目标, 这不仅是为了使学生感知理解文本语言表达的特点, 更重要的是使学生运用语言丰富文本内容, 习得语言表达能力。

3.关注学情, 切准实际, 自然衔接。对于有序表达的方法, 此前学生已经接触过一些, 如三上第13课《花钟》第1自然段的时间顺序法、三下第5课《翠鸟》第1自然段的方位顺序法、四上第3课《鸟的天堂》第12自然段先后词语连接法, 四上第21课《搭石》第2、4自然段集中出现了用关联词有序表达这一新的方法。把《搭石》的课堂核心练习目标定位为学习运用关联词有序表达的方法写画面, 顾及了学生的“最近发展区”, 促进了学生语文能力的提升。

三、有序展开单篇练习过程

单篇课堂练习是一种慢的艺术, 因为要想真正掌握一种语文能力, 不是一蹴而就的, 需要慢慢地走, 慢慢地练。

1.细化练习目标, 从低目标向高目标迈进。在切准《搭石》练习核心目标“学习运用关联词有序表达的方法写画面”的基础上, 将核心练习目标分解成5个子目标:明确练习方向寅初步感知文本整体表达有序寅感知用关联词连接法有序表达的方法寅深化用关联词连接法有序表达的方法寅迁移用关联词连接法有序表达的方法, 使每部分的练习有目标, 呈螺旋上升的渐进态势发展。

2.遵循认知规律, 从感知理解向强化运用递升。在《搭石》练习设计时, 根据学生的认知过程及语文教学的规律, 将课堂练习的过程分成感知、理解、发现、积累、强化、运用等几个步骤, 设计了几个层次的练习:

篇4：8b unit6 单元练习

一、关注“内容理解”, 依托“同步阅读”, 实现课内向课外拓展

正所谓“温故而知新”。单元复习课要对本单元所学过的知识“温习”。但是, 复习课总归不是新授课, 要突出“有所提升”的原则, 所以这种“温习”就不能是简单地、机械地重复, 而应该尽量在原有知识基础上向外拓展。平时的新授课教学由于受到教学进度、教学目标、教学时间等因素的限制, 不能随意拓展。复习课已不再受这些因素过多地制约, 已经具备拓展的条件。于是我依托“同步阅读”, 设计了这样的复习单 (以《詹天佑》为例) :

1. 我印象的是:詹天佑。原因是:他主持修筑了我国历史上第一条铁路干线。课文中打动我的句子有:

(1) 詹天佑不怕困难, 也不怕嘲笑, 毅然接受了任务, 马上开始勘测线路。

(2) 火车怎样才能爬上这样的陡坡呢?詹天佑顺着山势, 设计了一种“人”字形线路。

(3) 遇到困难, 他总是想:这是中国人自己修筑的第一条铁路, 一定要把它修好;否则, 不但惹那些外国人讥笑, 还会使中国的工程师失掉信心。

二、聚焦“表达形式”, 借助“选学课文”, 达成“必学与选学”贯通

人教版选录的课文, 文质兼美, 无论“内容”、“涵义”, 还是“形式”, 三者都堪称完美又和谐统一。宗白华先生引用歌德的话说:“内容人人看得见, 涵义只有有心人得之, 形式对于大多数人是一个秘密。”表达的形式, 往往承载文章的内容和形式, 中间又隐匿着作者的智慧与表达的技巧。表达形式如此重要, 也应该是复习课要聚焦的焦点之一。

一册教材是以课文和单元作为结构单位的。当一篇篇文章按一定的专题被编排在一起时, 无论是精读课文和略读课文的精妙选择与穿插, 还是每册书后选学课文的选择, 都倾注着编者的独具匠心。我们教师拿到一册教材后, 往往会仔细研究“精读”和“略读”这些必选课文, 而忽视“选学”课文。不仅如此, 即使在“精读”和“略读”教学过程中, 一篇课文教完马上又转入到下一篇课文的教学, 教师有时也会引导学生比较某几篇文章写法和内容上的异同, 但是鲜有整组课文的比较, 更难有必学课文和选学课文的贯通。学生所学习的知识和训练的能力, 还是相对的一个个点状或块状的, 没能形成一个相互联系、互相贯通的系统网络。于是, 我尝试借助“选学课文”, 在复习四上第五单元时, 设计了如下的复习单:

1.自学选学课文第5课《迷人的张家》并填空:作者来到张家界, 领略了仙境般迷人的景色:最使人难忘的? () , 群峰中最高的 () 和美丽的溪流 () 。因为有了这些奇山秀水, 张家界便成了植物的宝库、动物的乐园。迷人的张家界是名副其实的人间仙境。

2.作者来到张家界, 留下深刻印象的是:金鞭岩、黄狮寨、金鞭溪。因为:金鞭岩 () , 黄狮寨是 () 和金鞭溪是一条 () 。

3.选择印象深刻的景物来写, 是《迷人的张家界》这篇课文作者的写法。你知道本组课文其他几篇课文作者是怎样写的吗?

(1) 《长城》作者先写 () 再写 () 。

(2) 《颐和园》作者是按 () 顺序写的。

(3) 《秦兵马俑》作者先写兵马俑 () , 然后写 () 。

四上第五单元“世界遗产”的学习重点是:认真阅读课文, 留心文章表达的方法。“我的发现”安排的是发现句子的表达方法, 体会写出事物特征的写法。学生是第一次接触到游记类课文, 课文写了哪些景物, 四年级的学生有能力读明白。至于怎么写具体、写生动、写出事物的特征, 是新授课教师教学的重点。我觉得单元复习课上, 教师应该引导学生对话编者, 揣摩编者安排这几篇文章的意图, 于是我想到了将选学课文设计进复习单:第1题, 让学生自学《迷人的张家界》。尽管选文篇幅较长, 但是借助填空的形式长文短读, 学生就能比较容易地读出作者写了什么。第2题仍旧以填空的形式, 让学生明白作者之所以只选择这三处景物来写, 是因为这三处景物最有特点———金鞭岩最使人难忘, 黄狮寨是群峰中最高的, 金鞭溪是一条美丽的溪流———让学生体会抓事物特征的写法。第3题则是帮助学生梳理本组课文的不同写法, 学习几位作者不同的安排材料的方法, 感受编者的良苦用心。清代教育家颜彦曾说过:“讲之功有限, 习之功无已。”与其在复习课上, 再头头是道分析、总结给学生听, 还不如在这样的语言练习中, 达成“必学与选学”的贯通。

三、留意“语言现象”, 选取“配套作业”, 实现“习得与运用”转换

根据年段特点, 三年级上册起, “我的发现”的内容开始拓展, 从之前单纯地识字, 拓展到引导学生发现词和句的一些规律, 认识一些语言现象。教学时, 如果止步于这些现象的发现, 就未免有些“可惜”。如果能留意这些语言现象, 并将此应用到配套作业的练习中, 那么, 无论是学生完成作业题的质量, 还是单元复习的效果, 可能就会实现“双赢”。例如三上《课堂练习本》语文园地三第6题:

小练笔

秋天, 我们已经看到了你缤纷的色彩, 听见了你美妙的声音, 感受到了你带给我们的欢乐。

三上第三单元“心中的秋天”, 学习重点是:随着课文的学习, 进一步发现秋天的美丽和美好, 并用手中的笔来描绘。通过一组课文的学习, 学生已经看到了秋天缤纷的色彩, 听见了秋天美妙的声音。复习单第1、4题是对课文的回顾, 是对描写秋天色彩与声音词语的整理。第3题是帮助学生发现拟声词的形式特点, 第5题是本单元“我的发现”的拓展。复习单的1~5题都是为小练笔提供“素材”, 要实现的是语言习得与表达运用之间的转化。

总之, 单元复习单的设计要紧扣单元重点, 在帮助学生整理的过程中, 融入语言练习, 借助“复习单”这一载体, 进一步强化单元复习课的应有功能。学生借助单元复习单的练习, 单元知能体系得以建立, 训练程度也得到深入, 语文能力正逐步加强。需要指出的是, 教师在设计单元复习单的过程中, 还应注意不同层次学生的不同需求, 设计有差异的复习单;考虑从学生的实际出发, 设计由浅入深的复习单等。

摘要：现行的人教版小学语文没有专门的单元复习, 而语文园地、回顾拓展等其功能近似复习。但是在实际操作中很多教师却存在着只梳理不练习或者重整理轻练习的问题。笔者尝试设计紧扣单元重点, 在复习、整理的过程中融入语言练习的多功能单元复习单, 实现课内向课外拓展, 达成“必学与选学”贯通, 实现“习得与运用”转换, 以期实现教与学的双赢。

篇6：8b unit6 单元练习

一、单元构建的三要素

“技术、体能、运用”视角下的单元构建力求突破“技术线”的框架,改变“教教材”的现象,从学生的发展需要出发来构建单元。为此在单元构建的价值取向上主要体现以下三个要素。

(一)技术

运动技术是体育教学的媒介,运动技术就是体育课所必须传授的知识,这种知识是技能学科所特有的操作性知识,有了运动技术这种操作性知识的传习不仅使体育文化得到了传承,丰富了体育课堂形式,激发学生的学习兴趣,还能改造人体基本活动能力,使人通过掌握一定的基础知识和动作技能,强化体能。

(二)体能

运动技术的传习活动有助于强化体能或增强体质,为此体能的提高不是简单枯燥的重复练习,而是应该在运动技术的学练与运用过程中不经意地得到强化。体能的提高如果只是简单操作的量与强度的叠加,那结果就是现在所看到的不断涌现的“体育盲”,体能的提高也无法检验,也无从预期。

(三)运用

“能力与技能唯有通过实际运用才能发展”(裴斯泰洛齐《天鹅之歌》)。学习的结果在于“明白”,而“明白”的考验在于运用,学生不但要掌握运动技术,更重要的是要根据实际,创造性地运用所学的运动技术,使之“学以致用”。在运用的过程中,不必过于纠结动作技术的完整性,在技术的掌握及技能的运用上,不同的学生也有不同的差异,只要有耐心,要给予学生充分的练习机会,让学生在活学活用的过程中逐步巩固技术,获得良好的活动经历与活动体验,并在此基础上学习的能力得到了发展。

二、单元构建的步骤

根据“技术、体能、运用”三个维度构建的思维方式,首先要进行三维度的小单元构建,然后再合并成一个教学大单元。为此单元构建分为三个步骤,下面以水平二《足球运球(脚背正面、脚背外侧、脚背内侧和脚内侧)游戏与组合练习》单元(共8个课时)为例:

(一)单元目标及重难点的制订

单元目标及重难点的制订是根据《指导纲要》的“表现标准”来确定,“表现标准”指的是“学生学习该内容应该达成的基本要求”,主要确定学生经过学习后能知道什么、做什么、完成什么等,具有可操作性、可观察、可评估的特征,作为评价学生学习质量的基本依据。

为此本单元要求学生能说出3种运球时脚触球的部位,能在若干游戏中做出脚背外侧、脚背正面、脚背内侧、脚内侧四种运球方法中的三种即可,是学生学习的基本要求,给学生根据自身的情况有一定的选择,改变了必须学会或掌握全部运球动作的方法。并且明确了在游戏中做出不同线路、不同方式的运球要求,有了一定的量化标准(见表1)。

(二)内容单元的构建

内容单元是根据足球运球的教材内容按照“技术、体能、运用”三个维度分别设计三个小单元,使得每个小单元都有一个教学核心,这样使单元构建层次清晰,内容丰富。

1.技术单元

技术单元的核心目标就是使学生通过教学习得技能,从不会到会,课时分解时按照以往的方式进行,教学策略的选择就针对该目标。技术单元相当于新授课,以学会掌握动作或技术为主,3个课时(见下页表2)。

2.体能单元

体能单元的核心目标定位在用该教材内容发展体能的方法种类,并选择合适的方法围绕如何使学生学会这些方法展开教学,使体能的练习与动作的学习进行融合,学生在学习动作或方法的过程中体能无痕地得到提高,有利于提高学生学习的积极性。体能单元相当于练习课,是巩固和提高动作,采用的是多样的练习方法,2个课时(见下页表3)。

3.运用单元

运用单元的核心目标是习得技术后转化为技能,即技术运用能力的发展。就是要改变“为了技术而技术”的弊端,使学生学以致用,引导教师从项目特征、技术价值、觉悟需要等角度开展教学,设计相关的练习手段和方法。运用单元相当于复习课,是对所学动作要求更高的复习、巩固和提高,在组合练习、对抗练习、模拟比赛等环境中实现。共3个课时(见表4)。

(三)教学单元的构建

教学单元类似于教学进度表,是把“技术、体能、运用”三维度有效整合成多次课的教学内容单元,是教师上课顺序的依据。教学单元的排定从动作或技术上要体现出由易到难、从练习方法上要体现由简到繁、从练习形式上要体现出由单一到多元的梯度性与层次性,要确保学生足够的练习机会,保证课堂有一定的运动量,使学生的基本活动能力得到充分发展。

当以上三个维度内容单元确定后,就可以制订教学单元。各类内容单元只体现出一种维度,但是一节课的教学中尽可能要体现出多维度内容,内容单元中的教学策略尤如中药铺中的各味药材,教学单元就是根据需要选择合适的“药材”,组合成适合学生需求与发展的各剂中药,组合成的各剂中药就是教学单元的各个课次内容与教学策略(见下页表5)。

“技术、体能、运用”三个维度只是一种思维的方式,在实际操作时不能也不可能简单地把三者割裂开,而是为了操作更清楚,把它们分为技术单元、体能单元和运用单元三个内容单元。当合成教学单元时,就需要把三者进行有机的整合。在整合课的内容可能会出现以下三种类型(见图1):

1.单一型:就是在一节课中只体现出一个维度。

2.复合型:就是在一节课中体现出两个维度,如技术与体能的组合,技术与运用的组合,运用与体能的组合。

3.综合型:就是在一节课中三个维度都得到体现。

在一个教学单元中三种类型课所占的权重比没有统一的规定,应根据教学的需要来确定选择某一类型,但是更希望在教学中多呈现出复合型与综合型的课,使学生在学习过程中得到全面发展。

三、单元构建的注意事项

关于“技术、体能、运用”三个小单元的关系、课时量的分配等问题在《指导纲要》中已经有详细的阐述,在此就不再进行说明。但在球类单元的构建时,根据球类项目的特点还要注意以下两个问题:

(一)教学单元组合的多元性

本单元是球类单元,由于球类项目本身存在着趣味性强,练习变化多的特点,因此在教学单元的构建中只是出现了同类教材内容的组合,但也可以与其他项目组合。在实际教学中,教学单元的组合首先应根据实际需求,缺什么补什么,如足球比赛经常会出现摔跤的现象,让学生有自我保护的意识与能力,足球可以与滚翻进行组合;学生下肢力量薄弱,弹跳性差,排球扣球可以与纵跳练习进行组合。其次还要考虑教材的横向联系,如足球的界外球、篮球的头上传接球与实心球的动作相似,界外球与实心球、头上传接球与实心球就可以进行组合。

教学单元的组合可以是同项目的不同技术组合、不同项目的动作或技术组合、与身体素质练习的组合,组合的目的不是形式,组合注重的是学生运动能力的发展、活动兴趣的培养、运用能力的增强、身体素质的提升,不要被动作技术所束缚,只要符合人体生理规律,有利于学生的全面发展就可以大胆地进行组合。

(二)“技术、体能、运用”三维度的关联性

技术、体能、运用在理论上分清很容易,但在实际操作时不易划分清楚。三个维度的确定只是一种思维方式,在内容单元构建时,肯定会出现交叉的现象,这也是正常的,只要明确在一个维度内容单元构建时就是以该维度为核心目标,其他维度的出现都是连带性的,不必过于追求分清各个维度的界线。
