Sample passage

Nowadays, a lot of people are still suffering from unemployment. It can be a direct cause of poverty. As we know, poverty is a social phenomenon that can cause a series of social problems. The unemployed usuallyhave a low income even no income, so they have no money to improve their housing condition, to have a healthy diet, to buy medical insurance, and to take up good education. We all know many people are infected with AIDS because of the lack of education. So when the poor get serious disease like AIDS, or when accidents happen to them, they have nothing to do but wait for death. So with our country’s economic developing, government

programmes should be made to improve the health care condition of the poor. Homework

Topic虚拟语气[The Subjunctive Mood]

Aims: Let Ss learn something about The Subjunctive Mood.

Help Ss master the grammar

IP&DP:.如何通过练习帮助学生掌握相关内容。

1一些常见的虚拟语气的句型或结构。

2. 虚拟语气的特殊形式,即用来表示要求、建议、命令、提议、意愿等

的主语从句、宾语从句、表语从句和同位语从句中的虚拟形式。

3. 主从句表示不同的时间概念、事实或假设情况,从而交错成为复合虚

拟语气。

4. 含蓄条件句中的虚拟语气的表示愿望的虚拟形式。

Procedures

ST强化训练:虚拟语气

1.Were it not for the snowy weather, we___________all right.

A. would be

B. would have been

C. were

D. may be

A.条件句表示与现在事实相反的虚拟。

2. _________more careful, his ship would not have sunk.

A. If the captain were

B. Had the captain been

C. Should the captain be

B.条件句表示与过去事实的虚拟。

D. are not able

A.条件句表示与未来事实的虚拟。

4. If you asked your father you __________ permission.

D. maybe get

B.条件句表示与未来事实的相反。

5.____________today, he would get there by Friday.

A. Would he leave

B. Was he leaving

C. Were he to leave

D. If he leaves

C.条件句表示与现在事实的虚拟。

6. ______I you, I would go with him to the party.

A. Was

B. Had been

C. Will be

D. Were

D.条件句表示与现在事实的虚拟。

7.The millions of calculations involved, had they been done by hand, ______all practical value by the time they were finished.

A. could lose

B. would have lost

C. might lose

D. ought to have lost

B.这个句子中含有一个省略if,把助动词提前到主语they之前的虚拟条件句,该条件句表示对过去情况的假设,而主句中by the time they were finished 表明主句也应该是对过去发生的情况的假设,因而应该选(B)would have lost为正确答案。

8. Had Paul received six more votes in the last election, he_________our chairman now.

A. must have been

B. would have been

C. were

D. would be

(D)这道题目是一个混合虚拟语气的句子。条件句省略了if,把助词had提前到主语前面,表示对过去情况的假设,而主句中now表明了对现在情况的假设,所以应选would(should, could, might)+动词原形这种表达形式。四个选项中只有(D)是正确表达形式,故为正确答案。

9.ook at the terrible situation I am in! If only I your advice

A. follow

B. would follow

C. had followed

D. have followed

(C)题目中的第一句话表示的是现在真实的情况,而第二句话中所要表达的是应该做但事实上没有做的事,这种情况导致第一句话中真实情况的发生,故If only条件句假设的是过去一种情况,因此应该用had +过去分词,所以正确答案是(C)。

10.If the horse won today, it thirty races in five years.

A. would have won

B. won

C. must have won

D. did have won

A.从句对过去的虚拟。

11 There is a real possibility that these animals could be frightened, _______a sudden loud noise.

A. being there

B. should there be

C. there was

D. there having been

B.从句表示虚拟,而主句是事实。

12. I would have gone to visit him in the hospital had it been at all possible, but I ______

fully occupied the whole of last week.

A. were

B. had been

C. have been

D. was

(D)本道题目的前半句话是对过去情况的一种假设,但事实上并没有发生,而事实上没有发生的真实原因是句子的后半部分由but引导的转折句所表述的真实。因而but所引导的句子中应该用表示志过去事实相符合的表陈述的时态,即一般过去时。

13. I apologize if I you, but I assure you it was unintentional.

A. offend

B. had offended

C. should have offended

D. might have offended

(B)此题要求在if从句中选择适当的动词形式,以主句中的动词apologize(抱歉)来看,if从句中表达的内容应该是过去做的事,因此可以排除(A),因为(A)是现在时。(C)中should+have+过去分词结构表示本来应该做却没有做的事,在此不合题意。(D)选项中的might+have+过去分词表示对过去发生的事情很不肯定的猜测,它表达的内容还不能成为事实,所以藉此道歉真是不知从何说起,因此此处也不合题意。(B)had offended表示当时已经发生了的动作。这是复杂条件句:apologize 是现在,而条件句是表示对过去假设的条件句。

14. If you hadn’t taken such a long time to get dressed, we’d_________ there by now.

A. be

B. circles

C. is circling

D. be circling

(A)该句也是一个复杂条件句(或称作混合虚拟条件句)。条件句表示对过去情况的假设,而主句表示对现在情况的假设,但事实上却与此相反,所以正确答案应该是(A)。

15. The sun rises in the east and sets in the west, so it seems as if the sun

________round the earth.

A. were circling

B. circles

C. is circling

D. be circling

A)as if引导的从句要求用虚拟语气,表示同时或将来的情况,动词要用过去式(be动词用were)或would(could等)+动词原形,本句话中指的是当时的情况,所以要用过去式,故(A)是正确答案。

16. I wish that I ______ with you last night. D

A. went

B. have gone

C. could go

D. could have gone

17. I wish I_______ with her. D

A. would be

B. am

B. help

C. are helping

D. would help

21. If the Watergate Incident__________ Nixon would not have resigned from the presidency.

A. did not occur

B. had not occurred

C. was not occurring

D. be occurring

(B)had not occurred表示对过去的虚拟,条件句中要用过去完成式,主句中要用should(would, could, might)+动词原形的过去分词。

22. I hadn’t expected James to apologize but I had hoped.

A. him calling me

B. that he would call me

C. him to call me

D. that he call me

(B)had hoped是常见的要求其后的宾语从句用虚拟语气的句型,虚拟语气would+动词原形。

23. George would certainly have attended the proceedings.

A. if he didn’t get a flat tire

B. if the flat tire hadn’t happened

C. had he not had a flat tire

D. had the tire not flattened itself

(C)表示对过去情况的假设,主句动词形式为would(should, could, might)+have+过去分词,条件句为过去完成式,if可以省略,但要把had提前主语前面。(B),(D)的表达不符合英语表达习惯,所以(C)是正确答案。

24. The teacher suggested that her students_________experiences with ESP.

A. write a composition on their

B. to write composition about the

C. wrote some compositions of his or her

D. had written any compositions for

his

(A)suggest后面的从句要用虚拟语气形式,其形式为should(可以省略)+动词原形。

25. He speaks Chinese as fluently as if he ______a Chinese.

A. were

B. had been

C. is

D. has been

A.表示与现在相反的虚拟。

26. As usual, he put on a show as though his trip________a great success.

D. was

A.as though引导的与过去相反的虚拟。

27. Looking round the town, he felt as though he away for ages.

A. has been

D. could lift

D.as if引导的与现在事实相反的虚拟。

C. confirms

D. must confirm

31. Without electronic computers, much of today’s advanced technology.

A. will not have been achieved

B. have not been achieved

C. would not have been achieved

D. had not been achieved

(C)这是一人含蓄虚拟条件句,通过介词短语without,表示潜在的一种假设,而主句中的情况也早已经发生,所以是对过去情况的一种假设,因此用would not have been achieved这一形式。

32. He told her to return the book in time so that others_________a chance to read it .

A. may have

B. will have

C. would have

D. might have

(D)连so that引导的从句中要求用虚拟语气,表示一种假设,形式为might+动词原形

小学三年级数学下第九单元集体备课《数 学广角》

新人教版小学三年级数学下第九单元集体备课《数学广角》 一、单元教学目标 1.使学生会借助直观图,利用集合的思想方法解决简单的实际问题。 2.使学生在解决实际问题的过程中体会等量代换的思想。 二、单元教学内容 和前几册教材的思路相同,第六册册教材除了在有关单元渗透相应的数学思想方法以外,还专门安排了“数学广角”这一单元来介绍一些数学思想方法,使学生运用这些数学思想方法来解决一些简单的实际问题或数学问题。第九单元主要是结合实际,使学生初步体会集合(例1)和等量代换(例2)两种数学思想方法。 1.集合思想是数学中最基本的思想,甚至可以说,集合理论是数学的基础。从学生一开始学习数学,其实就已经在运用集合的思想方法了。例如,学生在学习数数时,把1个人、2朵花、3枝铅笔用一条封闭的曲线圈起来表示,这样表示出的数学概念更直观、形象,给学生留下的印象更深刻。又如,我们学习过的分类思想和方法实际上就是集合理论的基础。 本单元的例1就是借助学生熟悉的题材,渗透集合的有关思想,并利用直观图的方式求出两个小组的总人数。 2.等量代换是指一个量用与它相等的量去代替,它是数学中一种基本的思想方法,也是代数思想方法的基础。等量代换思想用等式的性质来体现就是等式的传递性:如果a=b,b=c,那么a=c。 例2就是通过解决一些简单的问题,使学生初步体会等量代换的思想方法,为以后学习简单的代数知识做准备。 三、具体编排 1.例1。 本例首先通过统计表的方式列出参加语文小组和数学小组的学生名单,通过统计表可以看出:参加语文小组的有8人,参加数学小组的有9人。但实际上参加这两个课外小组的总人数却不是17人,引起学生的认知冲突。这时,教材利用直观图把这两个课外小组的关系直观地表示出来。从图上可以很清楚地

人教版三年级数学下册集体备课第九单元数学广角

人教版三年级数学下册集体备课第九单元数学广角 一、主备人:## 二、内容:第九单元数学广角 三、单元教材简析: 和前几册教材的思路相同,本册教材除了在有关单元渗透相应的数学思想方法以外,还专门安排了“数学广角”这一单元来介绍一些数学思想方法,使学生运用这些数学思想方法解决一些简单的实际问题或数学问题。本单元主要是结合实际,使学生初步体会集合和等量代换这两种数学思想方法。 集合思想是数学中最基本的思想,甚至可以说,集合理论是数学的基础。从学生一开始学习数学,其实就已经在运用集合的思想方法了。例如,学生在学习数数时,把1个人、2朵花、3枝铅笔用一条封闭的曲线圈起来表示,这样表示出的数学概念更直观、形象,给学生留下的印象更深刻。又如,我们学习过的分类思想和方法实际上就是集合理论的基础。 四、单元教学目标: 1、使学生会借助直观图,利用集合的思想方法解决简单的实际问题。 2、使学生在解决实际问题的过程中体会等量代换的思想。 3、通过学生动手操作,发挥各种直观手段的优势,组织学生开展探究学习。 五、教学重点难点: 重点:体会集合,等量代换这两种数学思想方法。 难点:用集合圈(韦恩图)表示事物(元素)。 六、课时安排:数学广角2课时 七、教学建议: 1、有层次推进,逐步渗透数学思想方法。 例1的教学时,可以先引入没有重叠的数学问题,求一共有几人?顺着学生的思路,求一共有几人就是把两个小组的人数合起来,引出直观图。再引入有重叠的数学问题,求一共有几人?引发认知冲突后,再让学生利用直观图解决问题,并解释直观图。例2也可采用逐步深入的方法展开教学。这样引入,符合学生的认知规律,由浅入深,逐步推进。 2、提供丰富的生活中数学素材,体验数学思想方法。 在本单元中,通过提供丰富的生活中容易理解的题材,使学生在大量感性经验的基础上初步体会这两种思想方法,为后继学习时的抽象、概要可以打下必要的基础。这里的丰富有两层含义:第一是提供更多的生活中的数学素材。因为教材上例题和练习只有7题。我们还可以补充更多的符合学生认知水平的素材让学生去体验,感受数学的思想方法。如:一只小狗的重量等于2只小猫的重量,4只小猫的重量又等于2只小兔的重量,1只小狗的重量等于几只小兔的重量?又如:王老师出了两道题,在第一小组的12人中,做对第一题的有8人,做对第二题的有10人,每人至少做对一题,两题都做对的有几人?等等。第二是根据学生情况提供多种形式的数学素材。有情境图的,有图片的,有文字描述的,有图片加文字描述的等。在这些具体的、丰富的问题解决过程中,可以帮助学生感受到情景变化了,但蕴含其中的数学思想方法没有变。 3、运用直观方式,理解数学思想方法 集合和等量代换的理论都是比较系统、抽象的数学思想方法,而三年级学生的数学思维以形象思维为主,让学生抽象地想像、理解数学思想是有困难的,教学中可以充分利用学具、多媒体软件等教学辅助手段,用直观的方式帮助学生理解,如用圆片代表西瓜,用小方块代表砝码,用三角形片代表苹果,通过摆学具,可以比较容易地找出相互之间的等量关系。而且直观也是解决问题的一种策略,可以减少记忆量,使自己解决问题的过程清晰,有序。

最新部编版一级语文下册第八单元教材解读及教学设计资料讲解

部编版一年级语文下册第八单元教材解读及教学设计 第八单元教材解读 一、基本结构 本单元围绕“科普知识”这个主题,安排了三篇课文:《棉花姑娘》《咕咚》《小壁虎借尾巴》。《棉花姑娘》《小壁虎借尾巴》是童话故事,《咕咚》是一个民间故事。课文融科学知识和生活常识于故事情节中,既有教育性,又富有童趣。本单元还安排了“语文园地”,包括“识字加油站”“我的发现”“字词句运用”“日积月累”“和大人一起读”等。 二、主要特点: 《棉花姑娘》课文采用童话的形式,寓生物常识于生动形象的故事之中,通过棉花姑娘请求燕子、啄木鸟等给自己治病的故事,告诉我们燕子、啄木鸟、青蛙和七星瓢虫分别吃什么地方的害虫的科学常识。语言符合儿童特点,对学生了解科学知识有较强的启发作用,从而激发学生对学习科学常识的兴趣。 《咕咚》一课讲的是一个木瓜从树上掉进了湖里,发出“咕咚”的声音,兔子听见了吓得拔腿就跑,其他小动物没有搞清楚事情的原委也跟着一起跑,结果虚惊一场的故事。告诉我们无论做什么事,都不应该盲目地随大流,而要问个为什么,弄清事情的真相。 《小壁虎借尾巴》这是一篇童话故事,讲的是小壁虎向小鱼姐姐、老牛伯伯、燕子阿姨借尾巴,却因它们各自的尾巴都有用处而借不到之后发现自己又长出了一条尾巴的故事,让学生了解壁虎、小鱼、黄牛、燕子尾巴的功能及壁虎尾巴可以再生的特点。 《棉花姑娘》告诉学生不同的动物能消灭不同的害虫;《咕咚》以木瓜掉湖中的声音引起小动物们惊慌逃窜的故事,让学生初步懂得遇事要学会思考,不盲目跟从;《小壁虎借尾巴》则让学生知道动物尾巴有不同作用,壁虎尾巴有再生功能。学生可在本单元教材的学习中,了解一些科学常识,引导他们主动留心身边的科学,对科学产生浓厚的兴趣,产生探索、发现的欲望。 三、单元教学目标 1.会认45个生字,会写21个生字。

最新人教版四年级数学上册第九单元 集体备课教案

◎教学笔记 9总复习 总复习内容主要涉及本册教科书中四个主要内容,分别是大数的认识、乘法和除法的运算、空间与图形、统计与数学广角。通过总复习,学生对本学期所学的知识进行整理和复习,进一步巩固数的概念,提高计算能力和解决问题的能力,发展空间观念、统计观念,获得自身数学能力提高的成功体验,全面达到本学期的教学目标。正因为总复习的目的就是对本学期所学知识进行归纳整理,使之条理化、系统化,所以教学中要把握两个关键点:一是查漏补缺,进一步巩固深化数学知识和技能;二是沟通联系,构建知识体系,深化对知识的理解,提高学生综合运用知识解决实际问题的能力。 本册教科书四大版块的内容学生基本已经掌握,欠缺的是厘清知识脉络、查漏补缺的能力以及科学有效的复习方法。所以复习的重点应该放在引导学生复习巩固的基础上,让学生初步形成数感、符号意识、空间观念和数据分析观念,提高运算能力及解决问题的能力,并逐步掌握复习方法,形成良好的学习习惯。 1.抓住重难点知识,查漏补缺是复习课的一项主要内容,辨析含糊不清的认知,巩固强化薄弱环节则是复习课的重要任务。例如,复习“大数的认识”的一项重点内容就是大数的读写法,一方面抓住其重点内容“中间、末尾有0的数的读写法”进行复习,另一方面还要关注学生的思维易受知识负迁移的影响而产生思维障碍点。 2.复习课要加强各部分内容之间的联系,完善知识结构,建构知识网络。例如,复习“图形与几何”时,结合本册教科书知识较为零散、概念多的特点,教师要引导学生进行适当的系统整理,在构建知识网络的过程中,使学生更加直观、清晰地了解图形间的联系和区别,明确概念,内化理解。 3.复习时,既要加强知识间的横向联系,更要加强知识间的纵向联系。例如,复习“乘法和除法的运算”时,可以把因数和积的关系、商变化的规律与乘、除法口算结合起来复习,使学生进一步理解口算算理,并能灵活运用这些规律进行口算,使口算更准确、迅速。如学生前面学习60÷20时,对于为什么可以利用6÷2进行口算的原理不是很清楚,学习商不变性质之后,就可以说清其中的道理了。复习笔算乘、除法时还可进一步阐述乘、除法的互逆关系,在解决问题的过程中,通过让学生学会分析数量关系,知道何时用乘法,何时用除法等。

人教数学二年级上第九单元集备 教学目标: 通过总复习,使学生从整体上加深对所学知识的认识和理解,提高计算能力和运用所学知识解决简单的实际问题的能力;感知数学与现实生活的联系。以全面实现本学期的教学目标。 教学内容: 本单元复习包括本册所学的主要内容,总共分为五部分: 1、100以内的笔算加减法 2、表内乘法 3、长度单位和角的初步认识 4、观察物体 5、统计 内容安排突出知识间的内在联系,有利于复习时进行整理和比较。 学情分析: 本单元从内容看基本上含盖了二年级上册全部内容,学生对所学基本知识有了一定的了解和认识,但差异必然存在,尤其是对知识的系统把握和应用上会存在“学困生”。 像7—9的乘法口诀,数目比较大这样的内容,学生容易出现错误;米和厘米长度单位的实际意义比较抽象,有的学生难以把握;统计图中一格表示两个物体,这种数学中的“对应关系”也是学生比较难接受的;还有看图想象不同方向观察到的图形等等,在复习中都是需要给予足够重视的。 教学策略: 1、复习前,结合平时学生学习的情况认真分析缺差,拟订适合本班学情的复习计划,以便做到复习更有针对性。 2、充分发挥学生的主体作用,采取小组合作、讨论、交流的方式,引导学生自主学习,如运用乘法口诀解决实际问题、根据统计图提出其他问题、看图想象不同方向观察到的图形等,都可以在小组合作学习的基础上进行。 3、把数学知识的学习与现实生活联系起来。如长度单位“米”和“厘米”的理解,引导学生用自己身体的某部分或生活中的具体实物来比划;找角和直角与观察周围的实物联系起来;用乘法口诀解决实际问题等。 4、复习过程中做到既全面,又突出重点。100以内的笔算加法、减法是本学期学习的重点;表内乘法是进一步学习的基础,要让学生切实掌握好。长度单位、角的初步认识、观察物体和统计等也非常重要,复习过程中不可轻视。 5、引导学生对具体实物的观察(课前准备的三棱柱积木),运用量一量、画一画等具体操作,帮助学生直观体验和感知数学知识与生活的联系,以加深学生对知识理解。 复习过程中的练习和效果考察,主要是选用练习二十四中的练习和根据复习需要适当编写练习,或从《基础训练》册上选用,以补充练习,达到最佳复习效果。
