初中英语数词复习课件 篇4
(一)基数词
基数词用来表示数目,或者说表示数量的词叫基数词。最基本的基数词如下表所示。
1 one 11 eleven 100 a hundred
2 two 12 twelve 20 twenty 1000 a thousand
3 three 13 thirteen 30 thirty 1,000,000 a million
4 four 14 fourteen 40 forty 10,000,000 ten million
5 five 15 fifteen 50 fifty 100,000,000 a hundred million
6 six 16 sixteen 60 sixty 1,000,000,000 a billion
7 seven 17 seventeen 70 seventy
8 eight 18 eighteen 80 eighty
9 nine 19 nineteen 90 ninety
10 ten
说明:
1.13—19是由个位数加后缀-teen构成。注意其中13、15的拼写是thirteen和fifteen。
2.20—90由个位数加后缀-ty构成,注意其中20—50的拼写分别是twenty, thirty, forty 和fifty;80的拼写是eighty。
3.其它非整十的两位数21—99是由整十位数加连字符“-”,再加个位数构成。如: 81 eighty-one。
4.101—999的基数词先写百位数,后加and再写十位数和个位数。如: 691 six hundred and ninety-one。
5.1000以上的基数词先写千位数,后写百位数,再加and,最后写十位数和个位数。
如:5893 five thousand eight hundred and ninety-three。 在基数词中只有表示“百”、“千”的单位词,没有单独表示“万”、“亿”的单位词,而是用thousand(千)和million(百万)来表达,其换算关系为:1万=10 thousand;1亿=100 million; 10亿=a thousand million=a billion。
7.多位数的读法:
1)1000以上的多位数,要使用计数间隔或逗号“,”。即从个位起,每隔三位加一个间隔或逗号。第一个间隔或逗号前是thousand(千),第二个间隔或逗号前是million(百万),第三个间隔或逗号前是a thousand million或a billion(十亿)。
2)每隔三位分段以后就都成了101—999。读的时候十位数(或个位数)的前面一般要加and。如:
888,000,000读作:eight hundred and eighty-eight million。
(二)基数词的用法
1.基数词的复数形式表示大量的数目。
在这种情况下,表示单位的基数词(hundred, thousand, million, billion)不能在词尾加-s。
例如:
two hundred students 二百个学生
five thousand years 五千年
2.基数词的复数形式表示大量的 的数目,在这种情况下,表示单位的基数词词尾加-s,要与of短语连用。
3.基数词在句中的。作用
基数词的作用相当于名词和形容词,它在句子中可充当主语,宾语,表语和定语。
例如:
Three and five is eight. 3+5=8
主语 表语
How many oranges do you want?你要多少桔子?
I want eight. 我要八个。
宾语
There are eight boats in the lake. 湖里有八条小船。
定语
(三)序数词
表示顺序的词,叫序数词。序数词用来表示数词顺序。除特殊情况外,序数词一般都由相应的基数词加后缀-th构成。
请见下表:
第一到第十 第十一到第十九 第二十以上
first eleventh twentieth
second twelfth thirtieth
third thirteenth fortieth
fourth fourteenth fiftieth
fifth fifteenth sixtieth
sixth sixteenth seventieth
seventh seventeenth eightieth
eighth eighteenth ninetieth
ninth nineteenth hundredth
tenth thousandth
说明:
1.英语中表示第一、第二、第三的序数词属特殊形式,要注意它们的拼写。
2.表示“几十”的序数词通常是将基数词词尾y变成i再加上后缀-eth。
3.其余的二位数序数词是以相应的整十基数词加个位序数词。如:fifty-first(第五十一)。
4.少数序数词拼法不规则,如:fifth(第五),eighth(第八),ninth(第九),twelfth(第十二)等。
注意:
1.序数词可缩写为阿拉伯数字加序数词最后两个字母。
例如:
第一:(the) first=1 st
第二:(the) second=2 nd
第三:(the) third=3 rd
第五:(the) fifth=5th
第九十七:(the) ninety-seventh=97 th
第一百零一:(the) one hundred (and)first=101st
2.编了号的事物要用基数词表示顺序,但是基数词要后置。
例如:
第一课:Lesson One
第三十二页:Page 32
第305房间:Room 305
第12路公共汽车:Bas No.12
(四)序数词的用法
序数词和基数词一样,也能起名词或形容词作用,在句子中作主语、表语、宾语和定语。
例如:
The first is bigger than the second. 第一个比第二个大。
主语
Give me the first. 把第一个给我。
宾语
She’s often the first to go to school. 她经常第一个去上学。
表语
We’re going to learn the eighth lesson. 我们将要学习第八课。
定语

初中英语趣味课件 篇11
初中英语趣味课件
初中英语趣味课件
中学生爱说爱动、自我约束能力差,自我控制能力不强,这也导致学生不能安静地接受老师所讲的知识。如果教师只靠传统的教学模式,只是机械地教学,学生会对课堂失去兴趣,学生没有了学习的兴趣,没有了学习的积极性,更谈不上学习的主动性。因为兴趣是最好的老师,教师要在英语教学中想尽办法提高学生的学习兴趣,让学生在愉快的学习气氛中学习。
一、构建民主和谐的气氛,创建和谐的师生关系
英语教学的不足是学生在课堂上不够积极主动。教学中,我尽量给学生发言的机会,并对他们的积极发言给予肯定,让他们在这些鼓励性的语言中产生学习的积极性,消除他们心理上的障碍,让他们积极地发言。课堂上我坚持用英语和学生交流,比如交作业情况让学生用英语来表达,让学生尝试学习英语歌曲,课堂上让学生们用英语对话,通过各种形式来活跃课堂气氛。在课堂教学中借助于实物、卡片、挂图来加强直观教学,还根据学生回答问题的情况分别用“Good”“Very good”“Wonderful”“Well done”“Great”等具有评价性的语言来激发学生的学习兴趣,利用课堂营造和谐的师生关系,形成良好的教学氛围。初中生的“亲师性”非常强,如果学生对教师有了好感,那么他们对这一门课也比较感兴趣了,这门课的成绩也能较快提高。基于学生的亲师性较强特点,我在教学中,做到关心、爱护、尊重所有的学生,结合他们自身的特点来指导他们学习,让学生亲其师,信其道,构建起一种和谐的氛围。
二、采用灵活多变、富有情趣的教学方法
教学中如果只是一种教学方法会使学生感到学习枯燥、无味。再有魅力的教学方法也会失去吸引力。为了使英语教学更有趣,教师还要做到认真备课,认真钻研教材,结合不同的教学内容,选择不同的教学方法。为使英语教学更能激发学生的兴趣,在开始讲课前,用英语给学生讲能够听懂或者是大致能听懂的英语笑话、英语谚语或者英语小故事,还可以与学生进行三分钟英语会话的练习,学生用英语进行演讲或者集体唱一首英文歌曲等课前活动来活跃课堂气氛,使学生的学习兴趣得以激发,实现教学前的预热,提高学生的学习兴趣。还可以给句子改换人称、改对话为叙述、改叙述为对话、口头作文、看图说话、组句成文等不同的形式来为学生增趣。在这种灵活多变的教学方式下,将死教材教活,让学生热爱学习英语,达到良好的学习效果。
比如,在导入新课前,我结合不同的教学内容来设置悬念,有时提出问题,让学生更感兴趣,还可以利用直观的`教具进行演示等。在教学过程中,教师还要运用教学用具,比如,图片、挂图、简笔画等创设教学情境,再进行讲解。教师在讲解时,要注意做到有序、不重复,还要给学生留出接受的时间。教师要善于发问,不能单纯地讲,让学生成为课堂教学的参与者,不仅学到新的东西,还会用新的东西。
三、在实践活动中培养学生学习英语的兴趣
实践更能提高学生的学习兴趣,在实践活动中可以巩固学生的英语学习兴趣,实践活动是不可缺少的重要环节,它为学生创造了更多练习英语的机会。学习英语主要是为了与别人交流,它是一种交际语言。课堂练习时间是有限的,为使学生能更好地运用英语进行交流,还要在实际生活中加强英语的运用,完成了课堂教学内容以后,我还开辟了一个师生、生生交流平台,利用这一个平台进行交流,进一步激发了学生的学习兴趣。我在学生学完所有的日常用语后,主动用这些日常用语和学生打招呼,他们也顺其自然地用所学的英语进行回答,学生明白了这些用语的运用环境,用起来也就更大胆了,他们进一步弄懂了如何在实践中学习语言,开口说英语的胆量也得到了锻炼,同时学英语的兴趣也提高了。
对于中下游学生来说,他们没有学习英语的信心与恒心。教师还要以朋友的身份与学生进行交流,引导和激励学生。对于有进步的学生要投以赞许的目光,让学生在愉快的心境和期待的目光中越来越出色。在英语课堂上还要设计一些比较简单的问题,让学生思考,在学生回答问题时,教师还要不时地给他们暗示和指导,让他们在课堂上有充分展示自己的机会,让他们感觉自己也能学会,也能学好,他们感觉到自己一点也不比别人差,对学习就会更有信心。比如,在学习与动物有关的名词时,我先从网上下载与之相关的图片,再通过power point及flash制作成为教学所用的课件,在课堂上借助多媒体进行播放。吸引人的动画、动听的音乐、多彩的画面使教学达到了良好的效果。另外,在学习某些动词时,比如,ride(骑)、throw(扔,投掷)、jump(跳)、cry(哭)、laugh(笑)时,我也选出几名学生进行表演,有了这些真实动作,学生们更感兴趣了,我有时还让学生搬辆自行车放在教室里ride(骑)、做个纸飞机让几名男生throw(扔,投掷)、再买几根跳绳让一些学生jump(跳),等等,还让学生扮作“摄影记者”来拍照,把这些动作放在电脑上一起欣赏。学生在实践中学到并掌握了知识,培养了乐趣,课堂上出现了师生互动——生生互动的场面,学生是主体,老师是主导,学生由被动学习变为主动学习,学生感觉学习是快乐的,充满乐趣的。
在英语课堂教学过程中,为使学生的积极性得以激发并保持,使学生学习英语的乐趣更浓,整个教学过程始终贯穿学习兴趣的培养,使学生对英语学习的主动性更强。另外,我还不断地加强业务学习,对自己的教学方法加以改进和完善,使自身素质不断地提高,使课堂效率更高,为实现英语趣味教学而努力。
