1．This sheep is white.2. There is a desk and a chair in the room.___________________________________________________3.That man is a doctor.（2) 不可数名词不可数名词不能用数字计算包括物质名词( air, water等)及抽象名词(advice, hate)等。
所以它通常只有单数形式。
如：English, air, water, cotton, work…不可数名词表示数量时，可以用量词来表达(量词有复数形式)其结构是数词+量词+OF+名词。
如：a bottle of water,two cups of tea,three pieces of paper 注意事项：1．不可数名词没有复数变化，不能用A，AN，但可用THE，或不用冠词，如：bread is the usual breakfast.2．虽然不可数名词没有复数变化，但量词超过一时要加复数。
如：three cups of coffee, five bottles of water3．有量词修饰时注意名词是否可数，不可数时用单数，可数时用复数，如：ten bags of rice---- ten baskets of eggs找出不可数名词，在横线上打勾，并将可数名词变成复数形式：homework half money _____music ___chicken____ mouth _____bread _____information ______milk _____cow名词所有格一、表示有生命物的名词的所有格1.单数名词词尾加’s，复数名词如果词尾没有s，也要加’s。
the boy's bag 男孩的书包Mike's knife 迈克的刀子the children's room 孩子们的房间men's room 男厕所2.若名词已有复数词尾s，只加’the students' bags 学生们的书包the teachers' reading-room 教师阅览室3.表示几个人共有一样东西，只需在最后一个人的名字后加's。
如表示各自所有，则需在各个名字后加's。
如：This is Tom and Jason's room. 这是汤姆和杰森共有的房间。
These are Tom's and Jason's rooms. 这些是汤姆和杰森各自的房间。
二、.表示无生命物的名词所有格1、如果名词是无生命的，我们就要用名词+of +名词的结构来表示所有关系。
the windows of the house房间的窗户the title of the song 歌的名字the picture of the family 家庭照片2、在表示名词所有格时，'s结构可以转换成of结构。
the girl's name →the name of the girl 女孩的名字my father's friend →the friend of my father's 我父亲的朋友3、有些表示时间、距离、国家、城市等无生命的东西的名词，也可以加's来构成所有格。
