资源简介 小学英语语法第 1讲 字母1、英语中共有 26个字母。Aa,Ee,Ii,Oo,Uu是元音字母,Yy是半元音字母,其余是辅音字母。英语单词就是由这 26 个字母组合而成的。Aa 和 Ii 可以独立成词,分别表示“一个(张……)”和“我”的意思,Ii翻译成“我”时要大写。2、英语字母可以分为印刷体和书写体。在书、报、杂志上见到的一般都是印刷体。在四线三格上书写时应注意书写位置,可以记住以下口诀:大写字母不顶格,小写字母占满格。书写时还要注意字母的笔顺。3、英语句子的第一个单词的首字母要大写。单词与单词之间在书写时必须保持适当的距离,一般以空出一个小写字母的宽度为宜。句子的末尾要有标点符号。4、英语中的句号是一个实心圆点(.),省略号是三个居下的实心圆点(…),英语中没有顿号和书名号,顿号用逗号替代,书名用斜体字表示。5、英语缩写词PRC中华人民共和国

语音1、音素:语音的最小单位。英语中共有 48个音素,其中元音音素 20个,辅音音素 28个。元 单元音 /i:/,/ /,/ :/,/ /,/ɑ:/,/ /,/ :/,/ /,/u:/,/ /,/e/,/ /音 双元音 /e /,/a /,/ /,/ /,/a /,/ /,/e /,/ /辅 清辅音 /p/,/t/,/k/,/t /,/tr/,/ts/,/f/,/θ/,/s/,/∫/,/h/音 浊辅音 /b/,/d/,/g/,/d /,/dr/,/dz/,/V/,/ /,/z/,/ /,/r/,/m/,/n/,/ /,/l/,/w/,/j/2、元音:发音时气流不受阻碍。元音分为单元音和双元音两类。单元音发音时唇形和舌位不变;双元音发音时由一个元音向另一个元音滑动,唇形和舌位有一个变化过程,且前重后轻,前长后短。3、辅音:发音时气流受到阻碍。辅音分为清辅音和浊辅音两类。清辅音发音时声带不振动;浊辅音发音时声带振动。4、音标:用来记录音素的符号。为了避免与字母混淆,音标被放在斜括号/ /内。5、英语中的一个字母或字母组合在不同的单词中发音可能是不一样的,而相同的发音对应的字母或字母组合也可能不完全相同。6、开音节:以元音字母结尾或以一个元音字母加一个辅音字母再加不发音的 e结尾(r除外)的音节。元音字母在开音节中读长音,即该字母的名称音。闭音节:以一个或几个辅音字母(r除外)结尾。元音字母在闭音节中读短音。a e i o u/e / /i:/ /a / / / /ju:/ or

名词名词是指表示人和事物名称的词,可以分为专有名词和普通名词两大类。1、专有名词:特定的人、地方、机构等专有的名称。第一个字母通常要大写。e.g. Jim Green, New York, Bank of China,Peking University星期、月份、节日、学科、报刊名也是专有名词。e.g. Monday,May,Christmas,Spring

表示情感,状态,品质等抽象名称,如:love ,carelessness个体名词和集体名词多数可以用数目来计算,称为可数名词,有单、复数形式;物质名词和抽象名词通常无法用数目计算,称为不可数名词,一般只有一种形式。注 意:① 集体名词被看作一个整体时,表达单数概念。e.g. His family was well known in the town. 他家在镇里是名门望族。② 集体名词被看作若干个体的集合时,表达复数概念。e.g. His family are waiting for him. 她的家人正在等他。③ 集体名词表达多个集体时,也有复数形式。e.g. Our village is made up of 300 families. 我们村有 300户人家。3、可数名词复数形式的构成规则:① 一般名词在末尾直接加 s,清辅音后读/ s /,浊辅音和元音后读/ z

sheep-sheep deer-deer▲ fish表示鱼的数量时,单复数同形;表示鱼的种类时,复数为 fishes.e.g. My cat had two fish for lunch.You can see a lot of different fishes in the lake.4、不可数名词一般只有原形,没有复数形式,但是可以借助量词表示一定的数量。如果表达两个或两个以上的概念时,量词需要用复数形式,不可数名词不变。e.g. a bottle of water ,a cup of coffee,two glasses of milk ,five bags of rice▲ 这种形式用于可数名词时,量词和可数名词都要用复数。e.g. ten baskets of eggs5、既可用作可数,又可用作不可数的名词:不可数 room 空间glass 玻璃 可数paper 纸 a glass 一只玻璃杯iron 铁 a paper 一份报纸、论文、文件wood 木头 a iron 一个熨斗beauty 美 a wood 一片森林- 12 -a beauty 一个美人 a room 一个房间6、名词所有格① 在英语中,有些名词可以加’s 来表示所有关系,带这种词尾的名词形式称为该名词的所有格。大多数表示有生命的东西。e.g. Tom’s book② 如果复数名词末尾已有 s,就直接加 ’ 。e.g. the teachers’ office③ 如果一些物品为两者共有,只需在后一个名词后加’s ;如果为各自所有,则需在每个名词后加’s。e.g. Lucy and Lily’s bedroom.(Lucy 和
