第一课时 名 词一、概述1、名词的属性：表示人或事物的名称抽象概念的词叫名词。2、名词分普通名词和专有名词。普通名词是表示某一类人或事物，或某种物体或抽象概念的名称。如：teacher, desks, plates, milk, box等，专有名词表示某一特定的人、事物、地方团体、党派、国家机关、语言、节日等专用的名称。（运用）如：China, Chinese, Saturday, June, Green, Beijing, Olympic等。（专有名词的第一个字母要大写）二、可数名词与不可数名词1、可数名词是指表示人或事物，可以用数来计量的名词，有单复数之分。如：glass-glasses; book- books2、不可数名词是指所表示的事物不能用数来计量。如：paper, rice, water , milk, tea等。3、有些名词在特定情况下由不可数变为可数名词。Light travels faster than sound; (light：光线，不可数)The lights are on. (light：灯，可数)4、不可数名词的量的表示不可数名词一般无法用数来计算，前面不能用a或an或数词来表示数量，它的量往往借助于容器来表示。如：a glass of milk - four glasses of milk a piece of paper-two pieces of paper a bag of rice-three bags of rice三、可数名词的复数形式（识记、运用）1、可数名词在应用时有单复数之分，单数变复数有规则变化和不规则变化两种。规则变化情 况变化形式例词一般情况加-sgirls; books;以s,x,ch,sh结尾的名词加-esclasses; boxes; watches;brushes以辅音字母加y结尾的名词变y为i, 加escity-cities; baby-babies以f或fe结尾的名词变f,fe为v, 加esknife-knives; leaf-leaves以O结尾的名词potatoes; tomatoes；photos; kilos; bamboos; radios2、少数名词有不规则的变化形式policeman-policemen; man-men; woman-women; tooth-teeth; foot-feet; sheep-sheep; deer-deer;Japanese- Japanese; Chinese - Chinese; fish - fish四、名词所有格（运用）名词的所有格是表示所有关系的形式，它也有构成上的变化。1、单数名词变所有格，只需在词尾加 s;2、复数名词的词尾已有s，只需加 即可；3、复数名词的词尾若没有 s ，则应加 s ;4、如果表示某人或物为两人所共有，则在第二个人后面加 s ; 如：Da Mao and Xiao Maos room 如果不是两人共有，则在每个人后面都加 s; 如：Li Leis and Toms mother5、名词所有格结构通常用于表示有生命的名词，或表示时间、距离、地点等，而表示无生命名词的所有关系则用“of”表示。 如: the windows of house the picture of the family of 结构也能用于有生命名词的所有格。 a friend of my sisters a book of his第二课时 冠 词（一）一、概述冠词是一种虚词，在句子中不重读，本身不能独立使用。在汉语中没有这个词类。在学习冠词时，要注意这种加在名词前帮助说明名词所指的人或事物的词表示数量“一”时，与数词的区别；其表示“数量”的意义没有“one”强，这是学习中注意区别的。二、冠词的定义冠词是置于名词之前，说明名词所表示的人或事物的一种虚词，它不能离开名词而单独存在。冠词有两种：一种是定冠词(the Definite Article)；the 一种是不定冠词(the Indefinite Article). a an三、不定冠词的用法a用于辅音音素起首的单词前，an用于元音音素起首的单词前。1、当第一次提到某人或某物时，用a或an起介绍作用，如：What is this?
