小学英语语法大全(全套十八讲)

小学英语语法大全第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UN 联合国 WHO 世界卫生组织NBA美国职业篮球联赛KFC 肯德基 IT 信息技术 EQ 情商 CCTV 中国中央电视台kg 千克 a.m. 上午USA 美国 HK 香港 WTO 世界贸易组织 CBA 中国男子篮球联赛 ATM 自动柜员机 ID 身份证 CPU 中央处理器 BBC 英国广播公司 cm 厘米 p.m. 下午 UK 英国 SOS 国际求救信号 UFO 不明飞行物 VIP 贵宾 EMS邮政特快专递 IQ 智商 RMB 人民币 VOA 美国之音 No. 号码 6

第2讲语音 1、音素：语音的最小单位。 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。
