“十选九”讲义

从2008年起,词汇的考查放在了语篇中,着重强调语法和词汇知识在特定情景中的应用。试卷10道词汇题以10选9的方式分别考察了动词,形容词,名词,形容词,副词还包括现在分词和过去分词的形式。把词汇的考查放在了语言环境中,不是单纯的考查词汇,文章题干均清晰明了,并提供了足够的上下文支撑供考生答题。同时,词汇题的难度分布也较为合理,确保了各个层次的考生都能得分。因此,情景理解和语言运用的味道比较浓厚,注重考查理解能力和逻辑推理能力的试题较多。

题型特征

1、选词填空的特点

1) 文章不会太长(300词左右);一般来说第一句是文章主题句并且不设空;一般每隔15-30个

词会有一个空;空与空之间有完整意群。文章中会挖出九个空,但是给出了十个单词,让学生选择填空使文章完整,这就是新题型轮廓。

2) 方框中词汇难度不高,文章难度要略低于阅读理解难度。实际上是将词汇的使用和完形阅读

紧密结合的一道题目。

2、选词填空的考点

1) 词汇方面以实词为主也就是指名词、动词、形容词、副词。

2) 语法方面考察词性之间关系和句子结构分析能力。

3) 逻辑方面考察上下文联系

3、解题点拨:

1) 最关键的是要改变孤立的记忆单词的不良学法,做到词不离句,句不离篇,做到词汇的情景

使用。

2) 不要孤立的看文章,一定注意句子的上下文衔接和本句的语法结构,因为选一个就少一个,

一发而动全身。

3) 要专门记忆些高难词汇,也就是拼写很长词汇,比如:uninterrupted, alternative之类。

4) 要想到这些词汇是不是有些固定用法。

解题步骤

第一步:详读选项,词分类

选项中的10个词是考查的关键,考生应该详细的理解这10个单词。熟悉的单词标明词性和词义,不熟悉的单词或者不认识的单词只需标明词性,然后根据名词、动词、形容词、副词四大类按规律排列在试卷上。这样做考生就可以不再是10选1了,只要根据上下文的逻辑关系或者语法结构,有时候可以是3选1甚至2选1,缩小了选择的范围,降低了试题的难度。

注意:

1. 动词分为谓语动词和非谓语动词。非谓语动词包括:动词不定式、动名词、现在分词和过去

分词。过去分词有两种可能性(形容词和动词的过去分词), 无法确定时标问号。

2. 不认识的词要看后缀。构词法中, 前缀区分意思, 后缀区分词性。所以看词尾往往能大致分

出词性。词性无法确定的, 暂时搁置。

3. 做出相应的标记。在英文中有的单词不只有一个词性,比如大家常见的visit、access、approach、

challenge、change等就即有名词词性又有动词词性。这时两个都要标出来。

4.以-ing或-ed 结尾的词既可能是动词,也可能是由现在分词或过去分词转变而成的形容词。

例如:sleeping “She is sleeping。”中就是动词。而在“sleeping beauty”中就是形容词。

建议同学们在供选择的词旁将两种词性都标注上,答题时以动词为首选进行判断。

第二步:略读全文,定中心

考生拿到题目以后,由于考查考生对篇章的理解,应该略读整篇文章,确定文章的中心或主

要说明的问题。文章大概在220词--250词左右,用1分钟左右的时间略读即可。要抓住文章首句,迅速找到文章的主题词或主题。和完型填空一样,一般文章第一句不设空格,以便让考生知道本文的相关主题词或主题。在此,建议大家使用略读的方法,以快速掌握文章大意。

第三步:瞻前顾后,灵活选

词性分类之后,回到原文中,根据原文中空格的前后单词或者前后语句确定所要填的词性,然后从分类好的单词中选择出词性、意思、语法都符合要求的最佳选项。首先,根据语法知识确认可以被填入此空的词性,然后按第一步中标注出的词性进行筛选,最后将备选词逐个代入空中细读句意,考虑上下问逻辑关系做出选择。

第四步:复核检查,定结果

篇章词汇理解题目类似于完型填空,这需要考生不仅要迅速的确定答案,还要在确定答案之后迅速的复查。检查上下文是否通顺、上下文的逻辑结构是否正确、文章的意思是否出现偏差等等,复查无误后即可确定为最后答案。

解题技巧

(一)判断词性的技巧

前面提到的“瞻前顾后”就是需要考生根据空格的前后来决定所填词的词性以及应填的正确选项,我们可以根据一些简单的语法知识确定答案。应该说语法知识是解词汇理解题的基础。

1. 确定空格为名词

(1) a /an/the n. , adj. n. , vt. n. , 即空格处前面为冠词、形容词或者及物动词的,空格处应填入

名词;

(2) n. v., 即空格处后面是动词的,空格处应填入该动词的主语(名词);

(3) prep. n., 即空格处前面是介词的,空格处充当介词宾语,用填入一个名词或动名词。

2. 确定空格为动词

(1) n./pron. vt. n./pron., 即空格前面已有名词/代词作主语,后面又有名词/代词作为动词的宾

语,空格处应为及物动词;

(2) n./pron. vi. , 即空格处前面是名词/代词,后面没有宾语,空格处应填不及物动词;

(3) n./pron. vi. adv./prep., 即空格处前面是名词/代词,空格处后面是副词/介词,空格处应填入

不及物动词,与副词/介词构成固定搭配;

(4) n./pron. link v./be. adj., 即空格处前面是名词/代词,后面是形容词,空格处应填入系动词

或be动词;

(5) to v. , 即空格处前有不定式标志to,空格处应填入动词原形;另一种情况to是介词,后

面应填入动名词。

3. 确定空格为形容词

(1) adj. n. 或n. adj. , 即空格处前面或者后面为名词的,空格处应填入形容词;

(2)adv. adj. , 即空格处前面是副词的,空格处应填入形容词;

(3) link/be v. adj.,即空格处前面是系动词或be动词的,空格处应填入形容词作表语。

4. 确定空格为副词

(1) adv. v. 或v. adv. , 即空格处前面或者后面为动词的,空格处应填入副词;

(2) adv. adj., 即空格处后面是形容词的,空格处应填入副词。

(二)利用逻辑关系词确定答案

在篇章词汇理解题目中,文章的逻辑关系对于考生把握整篇文章是很重要的,文章的逻辑关系通过一些逻辑关系词体现的,考生可以通过逻辑关系词来确定出一些答案。

常见的逻辑关系词如下:

(1) 并列关系:and , or, as well as 等

(2) 对比关系:but , however , on the contrary , rather than 等

(3) 比较关系:as…as , like , similar 等

(4) 因果关系:because , for , since , as a result of , therefore , thus 等

(5) 举例关系:for example , for instance , such as ,and so on ;and the like等

(6) 递进关系:and , what’s more , moreover , in addition; then; next 等

(三)比较填词

将词性分类后,如何确定哪个选项是正确答案呢?这就需要考生进行选项间的比较,比较同词性的词汇哪一个是最佳答案。这里提示考生可以通过词义判断(即通过同词性词汇的中文意思是否符合文章的整体意思,由此判断是不是最合适的选项)和逻辑判断(即根据文章的逻辑顺序和逻辑结构,确定同词性的词汇中的哪个是最佳答案)两种方法确定答案。这里还要提示考生,填入一个词就划掉一个,为下面的选词缩小范围。

实例分析:

2009年上海市高考真题

A. contents

B. taking

C. carefully

D. plastic

E. packaging

F. declined

G. freely

H. typical

I. contracts

J. registered

If the package looks pretty, people will buy just about anything. So says an advertising executive in New York, and he has proved his point by selling boxes of rubbish for the price of an expensive bottle of wine.

Justin Gignac,26, has sold almost 900 41 presented plastic boxes of rubbish from the street of Big Apple at between $50 and $100 each. Buyers from 19 countries have paid for the souvenirs(纪念品). The idea has been so successful that he is thinking of promoting it around the world.

It all began when Mr Gignac was at a summer workshop, “We had a di scussion about the importance of 42 ,”he recalls.” Someone said packaging was unimportant. I disagreed. The only way to prove it was by selling something nobody would ever want.”

He searches the streets of Manhattan and typical 43 include broken glass, subway tickets, Starbucks cups and used 44 forks. “Special editions” are offered at a high price. He charged $100 for rubbish from the opening day of the New York Yankees’ stadium.

Mr Gignac denies 45 his customers for fools: “They know what they’re getting. They appreciate the fact that they’re taking something nobody would want and finding beauty in it.”

Some 46 customers include people who used to live in the city and want a down-to-earth souvenir. He claims he has even sold to art collectors.

Realizing that the concept appears to be a real money-maker, Mr Gignac has 47 a company and is employing his girlfriend as vice president. He 48 to discuss his profit margins: “It’s actually quite a lot of effort putting them together-but yes, garbage is free.”Mr Gignac is considering more varieties of souvenirs. He maintains that he has signed 49 with people interested in similar projects from as far as Berlin and London.

解析:41、C 本题考查根据句意选择合适的副词。本句意为“Justin Gignac, 26岁,已经卖出了近900个精心包装的塑料盒子,里面装的是从大苹果(纽约)的大街上捡来的废物,每盒售价在50到100美元”,句中的presented plastic修饰名词boxes,空格处应该选择副词修饰起形容词作用的过去分词presented。副词carefully在此意为“仔细地、精心地”,符合句意,所以C选项为正确答案。

42、E 本题考查根据上下文选择合适的名词。本段句意为“我们讨论了有关包装的重要性……有些人认为包装不重要,我不同意这种观点”空格前的介词可断定此处应填名词,所以E选项为正确答案。

43、A 本题考查根据句意选择合适的名词。本句意为“他在曼哈顿的街上仔细搜寻,寻找的典型物品(内容)包括破损的杯子……”, 根据句意和空格前的形容词和空格后的动词,可以断定此处应填入名词,所以A选项为正确答案。

44、D 本题考查根据句意选择合适的形容词。本句为43题所在句的后半部分,仍是说明典型物品包括哪些具体内容,意为“……和使用过的塑料叉子”,根据句意和空格前的形容词及空格后的名词,可以断定此处应填入形容词,所以D选项为正确答案。

45、B 本题考查根据句意选择合适的动名词。本句意为“Gignac先生否认将他的顾客当做傻瓜”,根据句意和空格前的动词和空格后的名词,可以断定此处应填入动名词taking作为动词deny的宾语,同时又和介词for构成词组,所以B选项为正确答案。

…….

46、H 本题考查根据题意选择合适的形容词。本句意为“一些典型的客户包括……”,根据句意和空格前的限定词和空格后的名词,可以断定此处应填入形容词,所以H选项为正确答案。

47、J 本题考查根据题意选择合适的动词。本句意为“发现这个理念确实可以赚大钱后,Gignac 先生已经注册了一家公司……”,根据句意和空格前的助动词和空格后的名词,可以断定此处应填入动词的过去分词形式,与前面的助动词一起构成谓语,所以J选项为正确答案。

48、F 本题考查根据句意选择合适的动词。本句意为“他婉言拒绝讨论他的利润空间”,根据句意和空格前的代词和空格后的不定式符号,可以断定此处应填入谓语动词,所以F选项为正确答案。

49、I 本题考查根据句意选择合适的名词。本句意为“他承认他已经于那些对类似项目感兴趣的人签订了合同,他们远在柏林和伦敦”,根据句意和空格前的动词和空格后的介词结构,可以断定此处应填入名词,所以I为正确答案。

备考方案

通过上面的解题技巧初探,可以归纳出下面的复习备考要点:

一、掌握正确的单词记忆方法

The pollution of the earth’s soil and water has become an issue of great concern. Until recently, most of that concern has focused on the land 41 of the planet, where pollution directly affects people in their daily lives. Now, however, we have begun to realize that marine (海洋的) pollution is 42 important. According to S.A. Patin, marine pollution is the condition that results when people introduce into the seas substances harmful to life, health, resources, activities, or 43 .

Marine pollution is far from new. For over a million years, people have thought of the sea as a 44 place to throw their garbage. And it is true that the sea has a great capacity for absorbing organic wastes. Some of these wastes are eaten directly by the larger fishes. Others quickly 45 into a kind of organic soup that provides food to 46 species of single-celled plant and animal life.

As civilizations grew, more different pollutants were dumped into the seas. Still, this pollution did not really threaten the marine environment. The seas seemed 47 of coping with anything that people could throw at them. This situation changed, however, when suddenly factories began dumping enormous quan tities of materials into the seas. Especially in some coastal areas near large cities, ocean pollution began to 48 marine life. For the first time, the oceans began to fail in their ability to 49 humanity’s waste.

When I succeeded in becoming a part-time employee of Nokia China l ast summer, many friends asked me how I survived the interview.

I once asked myself the same questions. Many of my peers also __41__ for the job, including some very competitive and intelligent students from famous universities.

But why did the interviewer pick me instead of them?

Finally, __42 __ pushed me to ask the interviewers after we became colleagues. The answer was that I appeared confident but humble, responsible and communicative. They evaluated people not just on their academic certificates, but on the base of their __43__ and abilities. I happened to be the right person.

To be frank, I once felt __44__ of being a student from an unknown college, and I think this may apply to some of you. I thought my future was ruined. It was only at the time of my successful interview that I finally understood the famous saying --- “You decide where you go.”

A wide range of skills is important these days. I used to work for Master Kong. My job was to cook instant noodles for customers. I had regarded it as a piece of cake, but I failed constantly. I had to cook the noodles for the right amount of time to make them taste good. Moreover, the noodles could only remain in a plastic cup of five minutes, or the taste would be __45__.

This experience taught me never to look __46__ on anything, and always remain humble.

I also worked as a volunteer for a beach volleyball event. My job was to help foreign visitors experience the beach. I thought it would be very easy because my oral English was __47__ good. But when I went to talk with a group of foreign guests, I suddenly realized that I did not know a single beach volleyball term. I was embarrassed.

After this, I read brochures in both Chinese and English every day to learn the terms for facilities and related words. This allowed me to deliver accurate __48__ to foreigners, and I was happy to work responsibly.

After these experience, I’m more confident and I strongly believe that my fate is in my __49__. It has certainly helped me make a giant step closer to my dream of graduating with prospects for the future.

I hope my advice will benefit you as well.

In the book Time to Eat the Dog: The Real Guide to Sustainable(可持续性)Living, New Zealand-based architects Robert and Brenda Vale say keeping a medium-sized dog has the same ecological 41 as driving 10,000 km a year in a 4.6 liter limousine. Calculating that modern house pet 42 through about 164 kg of meat and 95 kg of cereals a year, the Vales estimated the ecological footprint of cats and dogs, based on the amount of land needed to grow pet food.

“There are no recipes in the book,” Robert Vale said, 43 , in a telephone inter view. “We’re not

actually saying it is time to eat the dog. We’re just saying that we need to think about and know the ecological impact of some of the things we do and that we take for granted.” With pets’ diets under the control of owners, how can their unsustainable appetites be cut down? Changing their diets into 44 ones, the Vales say.

Instead they recommend keeping “greener”, smaller, and more sustainable pets, such as goldfish, chickens or rabbits. The book’s playful title, and 45 suggestion that pet animals may be usefully “recycled”, by being eaten by their owners or turned into pet food when they die, may not 46 to animal fans. Annoying as the idea may be, the question 47 from the planet’s growing population and limited resources, Robert Vale said. “Resources issues are 48 becoming things that are going to require us to make choices which are as difficult as ea ting your dog. It’s not just about changing your light bulbs or taking a cloth bag to the supermarket,” he said.

“It’s about much more challenging and difficult issues,” he added. “Once you see cats and dogs fit in your overall 49 of things —— you might decide to have the cat but also to have the two cars and the three bathrooms and be a meat eater yourself.”

面对新题型,我们考生应放平心态,客观处理。相信只要把握出题人思路和历年考点,无论高考题形式发生怎样的变化都是万变不离其宗。

Complete the following passage by using the words in the box. Each word can only be used once. Note that there is one word more than you need. Internet use appears to cause a decline in psychological well-being, according to research at Carnegie Mellon University. Even people who spent just a few hour’s a week on the Internet experienced more ___41_ and loneliness than those who __42__ on less frequently, the two-year study showed. And it wasn’t that people who were already feeling bad spent more time on the Internet, but that using the Net ___43___ appeared to cause the bad feelings. Researchers are puzzling over the results, which were completely __44__ to their expectations. They expected that the Net would prove __45__ healthier than television, since the Net allows users to choose their information and to communicate with others. The fact that Internet use reduces time __46__ for family and friends may account for the drop in well-being, researchers hypothesized. Faceless, bodiless “__47__” communication may be less psychologically satisfying than actual conversation, and the relationships formed through it may be shallower. Another possibility is that __48__ to the wider world via the Net makes users less satisfied with their lives. “But it’s important to remember this is not about the technology; it’s about how it’s used,” says psychologist Chirstine Riley of Intel, one of the study’s __49__. “ It really points to the need for considering social factors in terms of how you __50__ applications and services for technology.” students to deal with ___41_ English accents which are difficult to understand. This is good news for students who get ___42___ by different English accents. Computer scientists at Nottingham University said that some Asian students in Britian find it difficult to understand the range of different English accents. Among native English speakers, many different accents ___43___. Some accents are easily __44____ by certain characteristics. But more variations can be difficult to understand. Difficulties can be eperiencec in the process of differentiating sounds at the end of spoken English words, like rope versus robe, and at the start, like tin versus thin. This can make __45____ speech difficult to follow, as misunderstanding a single word can potentially change the whole ___46___ of a sentence. It would be useful to have something that would make it easier for foreign students to understand different English accents. The researchers’ Spoken English Discrimination (SED) training programme can train Chinese speakers in how to ___47___ differences in speech sounds in difficult conditions, such as accented speech or in situations in which there are a number of sounds in the background, a university release reported. “Our findings have shown that SED training programme really does have a significant __48____ on enabling Asian students to differentiate between sounds,”reseacher, Nicola Pitchford said. “There is a __49____ potential for SED.

8和9的组成教学反思 各位读友大家好,此文档由网络收集而来,欢迎您下载,谢谢 篇一:8、9的加减法教学反思 《8、9的加减法》教学反思 《8、9的加减法》是在学习8和9的组成的基础上安排的,教材提供一幅画有8个笑脸的图,让学生写出四个算式并计算得数的探索过程,掌握计算方法,并培养学生学习的兴趣和探索精神。本节课采用小组合作的教学形式,充分发挥学生的主体性,培养学生解决问题的能力,初步感受到数学与日常生活密切联系,体会到教学的乐趣。 首先让学生复习和巩固8和9的组成,为8和9的加减法计算打基础。然后我根据儿童的年龄特征,引入学生喜闻乐见的笑脸图,在老师的指导下,让学生写出5+3=8,3+5=8,8-3=5,8-5=3四个算式。让学生亲身经历了根

据一幅图写出四个算式的探索过程,使学生感受到“一图四式”与实际生活的联系。有关8、9的加减法计算,我分两个教学,一是通过摆学具计算两道加法算式和相应的两道减法算式;二是直接用“想一想”的办法计算两道加法算式和两道减法算式。 最后,我设计了各种游戏活动,用来巩固和应用所学的知识,调动学生的积极性,并且让学生体会到生活中处处有数学。将数学知识融入生动有趣的活动中,结合学生感兴趣的生活情境,让学生在玩中学,为学生营造一种愉悦的学习氛围。不仅轻松愉悦地掌握新知,更加重要的是培养和激发学生学习的兴趣,体会到数学与现实生活的联系。 这节课创设了大量的让学生动手操作,用眼观察、动口表达、用脑思考的小组合作学习的实践活动,学生始终在轻松、民主、和谐、愉快的氛围中探索学习,成为学习的主人。有效地提高了学生提出问题、解决问题的能力,从中

教学反思: 这节课从关注学生已有的生活经验,关注学生的生活背景,关注学生的学习方式,关注学生的主动发展,关注学生学习方法的评价等方面来设计,内容的呈现以“问题情景——建立模型——解释、应用与拓展”的基本模式展开。回顾整个教学活动,我认为在教学中较好地贯彻了课改的新思想,主要体现在: 1、创设情景,在活泼气氛中引发兴趣 《数学课程标准》指出:“数学教学活动必须建立在学生的认知发展水平和已有的知识经验基础之上”,而且“兴趣是最好的老师”。这节课,我根据教学内容,结合低年级学生的个性特点,大胆地创造、使用教材,从孩子熟悉的“钓鱼”这一生活情景出发引入课题,吸引了学生的注意,使学生一开始就处于积极状态中,激发学生的思维,激起学生学习数学的兴趣。 2、自学互学,在合作交流中感受快乐 “动手实践、自主探究与合作交流是学生学习数学的重要方式。”如今,“学生是数学学习的主人,教师是数学学习的组织者、引导者与合作者”,课堂上学生唱“主角”,教师只是一个“配角”,把时间和空间都留给学生进行思考、探究、交流,关注学生在学习的过程中表现出来的情感、态度、思维等方面。本节课的内容“8和9的分解与组成”,学生已有一定的知识经验,于是我放手让学生自己去尝试,

去自学,去思考,去交流尝试的结果。在这个自学、交流的过程中,真正理解的学生,印象必然较深,同时增强了自信心,激发了成功、愉悦感;不能理解的学生,也在自学中发现困惑所在,在小组合作、相互交流中,困惑得到解答,有恍然大悟之快感。 3、实践应用,在有趣的游戏、精彩的练习中感受乐趣 传统的课堂教学,学生听,老师说,机械重复,单调乏味,学生很难“活”起来,“动”起来。在本课中,我注意穿插游戏或组织一些有趣的活动,让学生在愉快的活动氛围中得到提高。如在巩固“8的组成”时,同桌合作做“拍手”游戏;又如在反馈练习中,师生共玩“数字卡片”游戏。做到师生互动、知情交融,教师与学生始终处于和谐、民主、欢快而又紧张的课堂气氛之中,实现教师与学生、学生与学生、学生与文本之间的零距离沟通。 总之,在课堂教学中,教师要设计生动、活泼的教学环节,不断地激发学生学习的乐趣和欲望,不断地使学生得到鼓励,体会到成功的喜悦,培养学生积极的情感。 最新文件---------------- 仅供参考--------------------已改成-----------word文本 --------------------- 方便更改 赠人玫瑰,手留余香。

高考十选九阅读巩固提升练习(七)(有答案)

高考十选九阅读巩固提升练习 Passage1 Researchers are placing robotic dogs(机器狗)in the homes of lonely old people to determine whether they can improve the 1 of life for humans. Alan Beck, an expert in human-animal relationship, and Nancy Edwards, a professor of nursing, are leading the animal-assisted study 2 the influence of robotic dogs on old people's depression, physical activity, and left satisfaction. "No one will argue that an older person is better off being more active, challenged, or stimulated," Edwards 3 out. "The problem is how we promote that, especially for those without friends or help. A robotic dog could be a solution." In the study, the robot, called AIBO, is placed for six weeks in the houses of some old people who live alone. 4 placing AIBO in the home, researchers will collect baseline data for six weeks. These old people will keep a diary to note their feelings and activity before and after AIBO. Then, the researchers will review the data to 5 if it has inspired any changes in the life of its owner. "I talk to him all the time, and he 6 to my voice," says a seventy-year-old lady, "When I'm watching TV, he'll stay in my arms until he wants down. He has a mind of his own." The AlBOs respond to certain orders. The researchers say they have some 7 over live dogs, especially for old people. Often the elderly are 8 and cannot care for an animal by walking it or playing with it. A robotic dog removes exercise and feeding concerns. "At the beginning, it was believed that no one would relate to the robotic dog, because it was metal and not furry." Beck says. " 9 i t's amazing how quickly we have given up that belief." "Hopefully, down the road, these robotic pets could become a more-valuable health helper. They will record their masters' blood pressure, oxygen levels, or heart rhythms. AlBOs may even one day have games that can help stimulate older people's minds. " IGBAE JDCH Passage 2

大班数学《8的分解与组成》教学反思

大班数学《8的分解与组成》教学反思Reflection on the teaching of decomposition a nd composition of 8 in large class

大班数学《8的分解与组成》教学反思 前言:小泰温馨提醒,工作总结是把一个时间段的工作进行一次全面系统的总检查、总评价、总分析、总研究,并分析成绩的不足,从而得出引以为戒的经验。本教案根据幼儿园工作总结的要求,将教学诸要素有序安排,确定合适的教学方案的设想和计划。便于学习和使用,本文下载后内容可随意修改调整及打印。 为了让xxx小学有效学习数的分解与组成知识,幼儿园的大班教材就已经安排了数的分解与组成内容,其中第一学期是5以内数的分解与组成,第二学期安排的是6至10这5个数的分解与组成,这也与《3至6岁儿童学习与发展指南》中对大班幼儿数学认知目标要求相符的。 第一学期大班的幼儿已经学习过了5以内各数的分解与组成,对于数的分解与组成,他们也已经有了一定的经验。尽管以往教学数的分解与组成时,所用的方法是不一样的,但还是发现,活动过程与方法都有些机械,不够灵活,所以本次活动前我用心思考:如何以游戏的方式来增强活动的趣味性,如何用操作来引发幼儿思维的活动? 去年10月份,我在园内公开课时,执教了《4的分解与组成》,活动结束后,大家一致认为我的设计非常好,就是没有给幼儿提供记录单。所以在后来的数的分解与组成活动中,我都给孩子们提供了记录单。本次在执教8的分解与组成时,我课前为每组幼儿准备了一张大的记录单和8个苹果图片及提前画好的一

棵苹果树。 参照教学用书中的活动设计,先学习8的组成,运用“结苹果”的游戏,幼儿很快也很顺利完成了活动任务,效果良好。在运用游戏“摘苹果”来学习8的分解时,我指名两个幼儿来进行“摘苹果”,其活动目标就是要求幼儿知道8具体能分成几和几,两名幼儿上台后,拭目以待,老师一声令下,“摘苹果”开始了,结果是a摘了4个,b也摘了4个,这样就把8分成了4和4,幼儿记录后,重新换幼儿,游戏继续进行,通过6轮游戏后才发现,8能分成4和4,出现了4次,8能分成5和3出现了2次,而8能分成1和7及其他情况均未出现,这是因为,每个幼儿都不想落后,都想在活动中表现自己,他们的能力相当,所以摘下的苹果数总是相差不多,如果用这种游戏方法可能很难完成活动任务,而且效果不佳,此刻,我机灵一动,打算重新考虑游戏方法,对幼儿说:“这个游戏经常出现重复现象,我们不玩了。”于是在美工区,拿来两个可比克的盒子,取来8根水彩笔,指名幼儿来分,告诉幼儿,每次分的要和别人的不一样,很多幼儿的常规思维就是等分,首先是8能分成4和4,接下来,就有幼儿将彩笔分成了5和3,当然也有重复的分法,但是通过引导幼儿观察,就会发现重复,于是掌握了规律的幼儿就在前面幼儿分的基础上,直接将一个盒子里的水彩笔,取出一支,放在另一个盒子里,幼儿们一边探究,一边分,一直将8的7种分法全部分完,并正确记录了下来,在此时,我依旧用鼓励的口气说:

2019届高三英语一模汇编——选词填空 1、2019黄浦一模 Directions: Complete the following passage by using the words in the box. Each word can only be used once. Note that there is one word more than you need. The Nile The ancient Greek writer Herodotus once described Egypt-with some envy-as‘the gift of the Nile’. The Egyptians depend on the river for food, for water and for life. The Ancient Egyptians were able to control and use the Nile, creating the earliest irrigation systems and developing a prosperous ___31___. Snaking through the deserts, the Nile would flood almost ___32___ each year in June. Once the water subsided, a rich deposit of sand was left behind, making an excellent topsoil. Seeds were sown, yielding wheat, barley, beans, lentils and leeks. Drought could spell disaster for the Egyptians, so during the dry seasons, they dug basins and channels to deliver water to their land. They also devised simple channels to transfer water at the peak of the flood. An early system of ___33___, a Nilometer, was used to determine the size of the floods. Later, during the New Kingdom, a lifting system called a shaduf was used to raise water from the river—___34___ to the way in which a well is used today. The Egyptians took up some of the earliest trading missions. Without a(n) ___35___ system they exchanged goods, bringing back timber, precious stones, pottery, spices and animals. Their efforts in medicine were also ___36___ advanced: surgeons performed operations to remove cysts(囊肿). Mummification gave them great understanding of the human body—yet they also relied heavily on various medicines to prevent disease, and discoveries were often confused with superstition(迷信). And while a great deal of time was dedicated to ___37___ , the Egyptians thought the stars were gods. By the 16th century Egypt was under the Ottoman Empire until Britain seized control in 1882. What is now mostly Arabic Egypt only won ___38___ from Britain after World War Ⅱ. The Suez Canal, opened in 1869, ___39___ the country as a center for world transportation. But it, and the completion of the Aswan High Dam in 1971 ___40___ the ecology of the Nile, which now struggles to satisfy the country’s rapidly growing population, currently more than 76 million—the largest in the Arab world. 答案:31-35GJABD36-40CEIHF 难度:中等
