How-many---How-much区别与练习

How many , How much的练习

1) many, much都表示“许多”, many修饰可数名词复数, much修饰不可数名词。many, much构成的词组有:too many, too much; so much, so many; a great many(修饰可数名词复数)。

【例如】

There are many peasants working in the field.Did you spend much time on your work? You have made so many mistakes that I even don't know how to correct them.As a student, one should read a great many books which are essential to enriching one's knowledge.

7、针对数量提问的特殊疑问句的基本结构是:

How many + 名词复数 + are there + 介词短语?

How much + 不可数名词 + is there + 介词短语?

Many和Much用法

①many和much都作“许多”解,但many用于修饰可数名词,而much修饰不可数名词。例如:

1. China has many oil fields. 中国有许多油田。

2. In our view, there is much oil here. 在我们看来,这里有许多石油。

②代词many和名词much用法举例:

1. Many of the students want to sum up the past experience before going on. 许多学生(原意为:学生中间有许多人)要总结一下过去经验在继续干。

2. Much of the waste acid is utilized. 废酸中大部分被利用了。

③“much(副词)+比较级”作“……得多”解:

1. The sun is much large than the moon. 太阳比月亮大得多了。

2. This problem seems much more difficult than that one.

这道题似乎比那道题难得多。

3. We turned back a much larger enemy force. 我们把力量强得多的敌人顶了回去。

④副词much修饰动词、过去分词时作“十分”解:

1. We all love Beijing very much. 我们大家都非常热爱北京。

2. We are much interested in heat utilization. 我们对热量利用十分感兴趣。

注:上述两种句子,一般不能用very代替much。

有时much也可修饰作表语用的形容词:

It is much the same. 差不多相同。

⑤ many和much的一些常用词组:

many a time 许多次 how many books 多少书 how much water 多少水

as much (many) 同样多 as much (many) as 像……那么多

倍数+as much (many) as………的……倍(那么多) much less 何况(用于否定)

much more 何况(用于肯定)

注1:much和many的比较级和最高级都是more和most,分别详见第337页和225页。“more(或most)+形容词或副词原级”还分别构成比较级和最高级。如:more useful较为有用的;most widely 最广泛地。

注2:“many a+可数名词单词”用法特殊,举例如下:

1. Many a worker often shows concern for us. (注意谓语用第三人称单数形式)许多工人经常关心我们。

2. Many a time have they been to Beijing.(注意Many a time作状语位于句首时,后面要引起主语、谓语颠倒现象,因为many a time和often近义,often位于句首时也引起主语、谓语颠倒。)他们去过北京多次。

much加不可数名词,如much milk

many加可数名词复数,如many apples

How many加可数名词复数,如How many pears

How much加不可数名词,如How much water

How much也可用于问价钱,如How much are the apples?意思是这些苹果多少钱?这是How many与How much的最大区别

2 many和much的用法:

〔1)many修饰复数可数名词,表许多; much修饰不可数名词,表量或程度。

He has many friends, but few true ones.

There hasn’t been much good weather recently.

(2)many a:

many a和many同义,但语气比较强,并且要与单数名词及单数形动词连用。

Many a prisoner has been set free. (=Many prisoners have been set free.)

〔3〕as many和so many均等于the same number of。前有as, like时, 只用so many。

These are not all the books I have. These are as many more upstairs.

They worked like so many ants.

(4)as much等于the same amount of, 表同量和同一事情。

He bought two pounds of sugar and as much tea. 〔同量)

I was not in the least surprised, for I had fully expected as much. 〔同一事情)

(5)many和much之后不接名词时,作为代名词;另外much也可用副词。

Many of them were very tired.

I don’t eat much for lunch. 〔代名词)

He is much taller than I. (副词〕

二用many,much 填空:

1.How _____ is that skirt?

2. How ______ people are there in your family?

3. How _______ rice do you need?

4. I have _____toys in my house.

5. How ______ bread is there in the box?

介词讲解,练习题及答案

四:介词 介词又叫前置词,是一种虚词。介词分为三种,一种是简单介词,如at, in, on, beside, to , for 等;另一种是短语介词,即由两个以上的词组组成的短语,如in front of, because of, out of, instead of等;还有一种叫二重介词,如until after, from behind等。 (一)介词的句法功能 介词不能独立在句中做成份,介词后必须与名词、代词、或动名词构成介词短语在句中充当一个成份,表示人、物、事件等与其它人、物、事件等之间的关系。 1、作定语:The book on the table is mine. 2、作状语:We have breakfast at seven.(表时间);They were late for meeting because of the heavy rain.(表原因);They started the machine by pressing the button.(表方法) 3、作表语:My dictionary is in the bag. 4、作宾语补足语:I found him in the office.

关于复习课的评价标准

关于复习课的评价标准 复习课是课堂教学的重要组成部分,是一段教学之后,教师引领学生巩固知识,提高能力的关键课型。复习课要和新课有本质的区别,既不是单纯的知识回忆课,也不是以做题为主的知识训练课,复习课教学的基本原则应是“温故知新、提高能力”。温故重在查缺补漏,凡是学生自学能够掌握的知识不再补,补的是那些学生容易遗忘和易于出错的知识。知新重在将旧知识进行归纳、概括,纳入新的知识框架,构建新的知识网络,同时在此基础上将知识升华为解决问题的能力,为学生提炼解决问题新方法。 复习课教学是一个师生再学习、再提高的过程,要突出知识的整合和应用,因此 一、复习课的主要任务应该包括以下几点: (一)再现旧知:帮助学生进一步巩固和熟练课程标准规定的要掌握的知识技能与方法;(二)构建网络:帮助学生梳理知识,形成网络,使知识系统化、结构化,以加深对知识的理解与记忆; (三)提升能力:帮助学生揭示解题规律,总结解题方法,进一步提高运用所学知识分析问题、解决问题的能力,并为学生进一步学习新知识打下良好的基础。 二、复习课一般由以下结构组成: (一)教师点明本节复习课的主要内容与要求; (二)师生系统回顾基础知识、弥补知识缺漏,使之形成网络与结构; (三)教师选择典型例题讲解或组织学生讨论,加深对知识的理解与应用; (四)学生独立练习,教师有目的地巡视辅导; (五)师生共同小结与讲评,并归纳、总结解题方法与规律,提高能力; (六)布置课后作业。 三、复习课的遵循原则 (一)基础性原则:在知识与技能上下足功夫。有意识地让学生多练习一些能直接运用基础知识来解的题目。 (二)主体性原则:把学生看成是学习的主体,凡是学生看得懂、讲得来、做得出的内容与题目,都要让学生去独立完成,教师不要都包办代替,不要满堂灌。 (三)系统性原则:通过复习要把平时所学的局部的、分散的、零碎的知识纵横联系,使之系统化、结构化。 (四)精选性原则:精心考虑例题的选择和习题的配备,帮助学生从中找出解题规律与方法。开阔学生思路,使学生通过复习有新的收获、新的体会。 (五)激励性原则:确定适当的教学目标和内容。在学生“最近发展区”上做文章,使学生始终处在一个兴奋的、投入的学习状态中。

练习课与复习课的联系与区别

练习课与复习课的联系与区别 一、关于练习课 练习课的定义 练习课是以多层次练习为主要内容和形式的一种讲、练、评相结合的课型。 练习课的任务 训练学生的技能技巧。 练习课的结构 揭题——练习——小结——检测。(每一种课型都有一定的结构,但不是千篇一律的,也不是一成不变的。练习课的结构是多样的,本文仅介绍练习课的一般结构,下面谈到的复习课的结构也是如此) 揭题——新授课揭示课题的方法丰富多样,练习课一般直接揭示课题。 练习——这是练习课的主要内容,通常有四个层次的练习组成。1、基本练习,练习的设计紧扣新知的主要内容,目的是巩固新知、形成初步技能。2、变式练习,练习的设计既从新知的“正面”出发,又从新知的“反面”、“侧面”出发,目的是深刻理解新知的本质属性、提高解题技能。3、综合练习,练习的设计结合新知重点与旧知的联系,目的是建立知识间的相互联系,形成系统的解题技能与技巧。4、创造练习,练习的设计是新知的拓展和深化,目的是进一步提高解题技巧。 小结——小结的重点应是总结由例及类的解题规律和解题方法。 检测——主要安排学生独立作业,通过这个环节了解学生的情况,并在评议时适当补漏。 练习课的误区 1、上成新授课。把书中的习题当作例题或补充同类型的例题进行讲解,这种教法降低了教学要求。 2、做多层次的习题。这种教法比较普遍,以为多层次的练习就是练习课的全部。其实练习课中的练习与师生的评议和小结是交织在一起的,特别是小结,它是练习课的重要环节,是对练习实践中解题方法、技能技巧的总结和推广,而做多层次的习题相当于做补充作业或小测验,这种教法降低了教学要求。 二、关于复习课

复习课的定义 复习课是以复习巩固所学知识为主要内容,并借助板书形成知识网络的课型。 复习课的任务 加深学生对知识的理解并系统化。 复习课的结构 揭题——回忆——整理——沟通——练习——总结。 揭题——复习课一般直接揭示课题,有时还同时列出复习目标。 回忆——由学生对所复习的内容进行回顾,学生可翻阅课本、相互提示。通常教师只是辅以提问或学生做基本的练习。 整理——分与合,即按一定的标准进行分类与合并,使知识条理化、系统化。这种既求同又求异的环节通常同板书结合起来,形成线状、块状、网状、表格等形式的板书。 沟通——进行纵向联系和横向联系,构成网络,形成知识结构,并通过深化练习使之转化为学生的认知结构。 练习——主要是综合练习,通过练习提高学生综合运用知识的能力,另外设计一至两题创造性练习。 总结——总结各知识间的相互关系,进一步明晰和完善学生的认知结构,通常借助板书完成全课总结。 复习课的误区 1、上成新授课。把教过的例题集中而又快速的复述一遍,这种教法是一种“快镜头”式的重复,学生的知识、技能及智力仍停留在原来的水平上。真正意义上的复习课应是原有知识的浓缩和深化。浓缩是把“厚”变“薄”,便于学生理解并形成认知结构。深化是拓展学生的思维,提高综合运用知识的能力。 2、上成练习课。这种教法虽使学生的技能得到提高,但没有形成知识结构及认知结构,学生掌握的技能也只是单一的,缺乏综合运用知识的能力。 3、做试题。这是最不负责任的做法,用大量试题练习代替复习课的组织设计,加重学生的负担,事倍而功半。 三、关于练习课与复习课

when和while的区别是

Period____8______ in Unit ___6_________ (Period_____20_____Week 4-6)Subject _Grammar (B) Teaching aims To use the Past Continuous Tense with while and when correctly Teaching interesting points of this class: The differences of when and while in Past Continuous Tense Teaching steps: I. Cooperation and intercourse 1. Check the preparation 2. Discuss in groups II. Question and explanation Check the exercises on page 101, and explain the differences between when and while. when和while的区别是: when只能用于一般时态 while可以用于进行时态 when conj. 在...的时候, 当…的时候 when 在绝大多数情况下,所引导的从句中,应该使用非延续性动词(也叫瞬间动词) 例如:I'll call you when I get there. 我一到那里就给你打电话 I was about to go out when the telephone rang.我刚要出门,电话铃就响了。 但是,when 却可以be 连用。 例如:I lived in this village when I was a boy. 当我还是个孩子的时候我住在这个村庄里。 When I was young, I was sick all the time. 在我小时候我总是生病 while 当...的时候 While he was eating, I asked him to lend me $2. 当他正在吃饭时,我请他借给我二美元。While I read, she sang. 我看书时,她在唱歌。 while 的这种用法一般都和延续性动词连用 while 可以表示“对比‘,这样用有的语法书认为是并列连词 Some people like coffee, while others like tea. 有些人喜欢咖啡, 而有些人喜欢茶。 as 当...之时,一边......一边....... I slipped on the ice as I ran home. 我跑回家时在冰上滑了一跤 He dropped the glass as he stood up. 他站起来时,把杯子摔了。 She sang As she worked. 她一边工作一边唱歌。 III. Rumination and evaluation when, as, while这三个词都可以引出时间状语从句,它们的差别是:when 从句表示某时刻或一段时间as 从句表示进展过程,while 只表示一段时间 When he left the house, I was sitting in the garden. 当他离开家时,我正在院子里坐着。 When he arrived home, it was just nine o'clock.

练习课和复习课教案的编写

练习课和复习课教案的编写 一、教学目标 三维目标要全面,即知识与能力、过程与方法、情感态度价值观要全,不可缺少,虽然不把“知识与能力、过程与方法、情感态度价值观”这几个字写出来,但是一定要在教学目标中把这三方面的内容体现出来;另外教学目标的定位要合理,表述要准确,具体全面,知识目标要具体化,不能虚化,使用的思想方法、策略要说明,也就是说要说明白、搞懂、交代清楚,上位目标要曾现出来。要体现习题课或复习课的特点:重在巩固新知,应用新知解决实际问题以及在解决问题的过程中培养良好的学习习惯,增强学习数学的热情。特别需要注意的是:不能使用被动性的字眼,如使学生……,让学生……,培养学生……等。 反例: 例如:整十、整百乘一位数的口算及估算练习 1.结合具体情境掌握整十、整百数乘一位数的口算方法,能熟练地进行口算。 2.积极参与探索问题的学习活动,培养学生的问题意识及合作精神。 (知识目标缺失估算,缺失数形结合,迁移推理等上位目标,情感目标偏) 教学目标: 1、复习除数是整十数除法方法。 2、让学生巩固除法竖式的书写格式。 3、使学生经历笔算除法计算的全过程,巩固算理和计算方法。 正例 例如:《分数的意义练习》中, 教学目标: 1、进一步体会单位“1”的含义,加深对分数意义和分数单位的理解,会用分数描述 生活中的现象。 2、通过直观的操作和建立数学模型理解有关分数的知识,在解决问题的过程中发展 数感,培养解决问题的能力。 3、感受分数与生活的密切联系,增强获得成功的情感体验。 正例 用字母表示数综合练习 教学目标: 1、进一步理解和掌握用字母表示常用的数量关系和计算公式的方法。 2、在具体情境中,初步建立用字母表示数量关系的数学模型,能借助直观的线段图 分析理解比较抽象的数量关系并用字母表示出来,充分体会用字母表示数的优越性。 3、在解决问题的过程中,感受符号的简洁性,体会用数学语言表达的价值。 二、问题回顾,再现新知 ?这一部分主要是对学习的内容进行简要的回顾,回顾要简短高效,主要包括知识 点和主要用到的方法等。问题的引出有多种形式,可以是概括性的问题,如上节课学习了什么知识?可以是具体的问题,如圆柱的表面积怎么求?也可以是习题的形式,引导学生通过对习题的解答,引出知识点。在这里不要绕的太远,不要花哨,话不要说的太远。总之,对知识点的回顾整理要全面、准确、具体、到位,为下一步的练习做好准备。 例子 ?在《分数的意义练习》中 ?1、单位“1”的含义。 ?同学们,什么是单位“1”?请举出几个实例。

when和while的用法解析、练习题及答案(附总结表格)

when和while的用法解析、练习题及答案(附总结表格) 一、讲解三例句: 1. The girls are dancing while the boys are singing. 2. Lucy’s mother is cooking when she gets home. 3. When/While Lucy’s mother is cooking, she gets home. 二、用when或者while填空 1.______ Margo was talking on the phone, her sister walked in. 2.______ we visited the school, the children were playing games. 3.______ Sarah was at the barber’s, I was going to class. 4.______ I saw Carlos, he was wearing a green shirt. 5.______ Allen was cleaning his room, the phone rang. 6.______ Rita bought her new dog; it was wearing a little coat. 7. He was driving along ________ suddenly a woman appeared. 8. _____ Jake was waiting at the door, an old woman called to him. 9. ______ it began to rain, they were playing chess. 10. She saw a taxi coming ______ the woman was waiting under the streetlight. 三、语法 while和when都是表示同时,到底句子中是用when还是while主要看主句和 从句中所使用 的动词是短暂性动作(瞬时动词)还是持续性动作。 1、若主句表示一个短暂性动作,而从句表示的是一个持续性动作时,用 When/While。如: He fell asleep when while he was reading. 他看书时睡着了。

WHEN与WHILE用法区别

WHEN与WHILE用法区别 when, while这三个词都有"当……时候"之意,但用法有所不同,使用时要特别注意。 ①when意为"在……时刻或时期",它可兼指"时间点"与"时间段",所引导的从句的动词既可以是终止性动词,也可是持续性动词。如: When I got home, he was having supper.我到家时,他正在吃饭。 When I was young, I liked dancing.我年轻时喜欢跳舞。 ②while只指"时间段",不指"时间点",从句的动词只限于持续性动词。如:While I slept, a thief broke in.在我睡觉时,盗贼闯了进来。 辨析 ①when从句与主句动作先后发生时,不能与while互换。如: When he has finished his work, he takes a short rest.每当他做完工作后,总要稍稍休息一下。(when = after) When I got to the cinema, the film had already begun.当我到电影院时,电影已经开始了。(when=before) ②when从句动词为终止性动词时,不能由while替换。如: When he came yesterday, we were playing basketball.昨天他来时,我们正在打篮球。 ③当从句的谓语是表动作的延续性动词时,when, while才有可能互相替代。如:While / When we were still laughing, the teacher came in.正当我们仍在大声嬉笑时,老师进来了。 ④当从句的谓语动词是终止性动词,而且主句的谓语动词也是终止性动词 时,when可和as通用,而且用as比用when在时间上更为紧凑,有"正当这时"的含义。如: He came just as (or when) I reached the door.我刚到门那儿,他就来了。 ⑤从句的谓语动词如表示状态时,通常用while。如: We must strike while the iron is hot.我们应该趁热打铁。 ⑥while和when都可以用作并列连词。

教学技巧 _ 复习课、练习课、讲评课三大课型的操作技巧

复习课的教学要求和一般结构 复习课的主要任务是复习巩固所学的知识,使学生加深对已有知识的理解,并把知识系统化、条理化。根据教学进度,可以分成单元复习、期中复习和期末复习。 复习课的教学要求 复习课的目的是通过对知识的条理化、综合化、系统化的整理,使学生对知识加深理解、牢固掌握、灵活运用。复习课要有利于建构知识结构,提示知识之间内在的、本质的和必然的联系。从纵、横两方面加深对知识的理解,弥补学习上的缺陷,减少记忆负担,防止遗忘,促进学生认知结构的形成和完善。 复习课要注意合理选择复习时机,根据艾宾浩斯的“遗忘曲线”规律来组织复习;要有目的、有计划地进行复习;在进行阶段复习或学期复习时,要把知识的纵、横联系提示出来,合理编织知识网络,形成紧密的知识体系;复习的方法要多样,要防止复习材料的相互干扰,要进行必要的超额复习;要注意发挥学生的主动性,促使学生独立思考,逐步提高学生对知识的梳理能力。 复习课的一般结构 (1)宣布复习的内容和要求。 (2)复习提示。对拟复习的内容作概略式的提示,帮助学生回顾总结已学过的知识,建立知识之间的纵横联系,加深对知识的理解,特别是重点内容。可以提出复习提纲,让学生讨论,也可以安排例题进行讲解,重点指导学生如何综合运用所学的知识解题。 (3)复习作业。这是复习课的主要部分。教师根据复习内容和要求,布置具有明确目的的复习题组,让学生练习,使学生通过复习作业,把知识串联起来,使之系统化、条理化、网络化,便于储存、提取和应用。在复习进行的过程中,可安排基本练习题,巩固、理解学过的知识。 (4)复习讲解。根据学生在复习作业时反馈出来的信息,有的放矢地进行系统讲解,关键在于把知识系统化、条理化,构建知识结构,并根据学生在复习作业时出现的问题,进行重点分析。

while、when和as的用法区别

as when while 的区别和用法 as when while的用法 一、as的意思是“正当……时候”,它既可表示一个具体的时间点,也可以表示一段时间。as可表示主句和从句的动作同时发生或同时持续,即“点点重合”“线线重合”;又可表示一个动作发生在另一个动作的持续过程中,即“点线重合”, 但不能表示两个动作一前一后发生。如果主句和从句的谓语动词都表示持续性的动作,二者均可用进行时,也可以一个用进行时,一个用一般时或者都用一般时。 1、As I got on the bus,he got off. 我上车,他下车。(点点重合)两个动作都是非延续性的 2、He was writing as I was reading. 我看书时,他在写字。(线线重合)两个动作都是延续性的 3、The students were talking as the teacher came in. 老师进来时,学生们正在讲话。(点线重合)前一个动作是延续性的,而后一个动作时非延续性的 二、while的意思是“在……同时(at the same time that )”“在……期间(for as long as, during the time that)”。从while的本身词义来看,它只能表示一段时间,不能表示具体的时间点。在时间上可以是“线线重合”或“点线重合”,但不能表示“点点重合”。例如: 1、He was watching TV while she was cooking. 她做饭时,他在看电视。(线线重合) 2、He was waiting for me while I was working. 我工作的时候,他正等着我。(线线重合) 3、He asked me a question while I was speaking. 我在讲话时,他问了我一个问题。(点线重合)

第七--when-while-as-区别及练习.

When while as区别 一、根据从句动作的持续性来区分 1、“主短从长”型:即主句是一个短暂性动作,而从句是一个持续性动作,此时三者都可用。如: Jim hurt his arm while[when, as] he was playing tennis. 吉姆打网球时把手臂扭伤了。 2、“主长从长”型:即主句和从句为两个同时进行的动作或存在的状态,且强调主句动作或状态延续到从句所指的整个时间,此时通常要用while。 I always listen to the radio while I’m driving. 我总是一边开车一边听收音机。 He didn’t ask me in; he kept me standing at the door while he read the message. 他没有让我进去,他只顾看那张条子,让我站在门口等着。 但是,若主句和从句所表示的两个同时进行的动作含有“一边……一边”之意时,则习惯上要用as。如: He swung his arms as he walked. 他走路时摆动着手臂。 3、“主长从短”型:即主句是一个持续性动作,而从句是一个短暂性动作,此时可以用as 或when,但不能用while。如: It was raining hard when [as] we arrived. 我们到达时正下着大雨。 二、根据主句与从句动作是否同时发生来区分 1、若主句与从句表示的是两个同时发生的短暂性动作,含有类似汉语“一……就”的意思,英语一般要用as (也可用when)。如: The ice cracked as [when] I stepped onto it. 我一踩冰就裂了。 2、若主句与从句表示的是两个几乎同时发生的短暂性动作,含有类似汉语“刚要……就”“正要……却”的意思,英语一般要用as(也可用when),且此时通常连用副词just。如: I caught him just when [as] he was leaving the building. 他正要离开大楼的时候,我把他截住了。 三、根据是否具有伴随变化来区分 若要表示主句动作伴随从句动作同时发展变化,有类似汉语“随着”的意思,英语习惯上要用as,而不用when或while。如: The room grew colder as the fire burnt down. 随着炉火逐渐减弱,房间越来越冷。 注:若不是引导从句,而是引出一个短语,则用with,不用as。如: With winter coming on, it’s time to buy warm clothes. 随着冬天到来,该买暖和衣裳了。 四、根据从句动作的规律性来区分 若暗示一种规律性,表示“每当……的时候”,英语一般要用when。如: It’s cold when it snows. 下雪时天冷。 五、根据主从句动作的先后顺序来区分 若主句与从句所表示的动作不是同时发生,而是有先后顺序时,一般要用when。
