Unit 4 Eat Well 语法+写作解析
一、语法解析
可数名词及不可数名词
*定义: 名词的数指数量，即“多少”。单数:表示“一”;复数: 表示“多于一”
*名词可数性:可数名词和不可数名词
*可数名词单数变复数规则
1.一般情况直接加s
如:star --stars; book --books 等
2.以字母s,x,sh,ch等结尾词直接加es
如:bus--buses; watch -- watches等
3.以字母f或fe结尾的词将f或fe变为v再加es
如:leaf--leaves; knife -- knives等
4.以辅音字母加y结尾的词变y为i再加es
如:baby -- babies; city -- cities等
5.以元音字母加y结尾的词直接加s
如:toy -- toys; monkey -- monkeys等
6.以es, se, ze, ge等结尾的词直接加s
如:face -- faces; orange-- oranges等
7.以辅音字母加o结尾的词若表示有生命力则加es
如:tomato --tomatoes; hero --heroes等
若表示无生命力则加s
如:photo --photos 等
8.不规则变化
改a为e型:man--men;woman -- women
改oo为ee型:tooth--teeth; foot -- feet
在词尾加-ren:child -- children
单复数形式相同:sheep; deer; Chinese; Japanese
常用复数形式或只有复数形式:noodles; glasses; trousers; thanks; clothes; chopsticks; people等
其他特殊形式:mouse--mice;老鼠;mouse -- mouses 鼠标
注意:1.有些以f或ef结尾的词直接加s变成复数:
如:roof--roofs;chief-- chiefs等
2.由man和woman 构成的合成词，其复数形式需前后都变复数:
如:man doctor -- men doctors; woman teacher -women teachers等
3.名词作定语修饰另一个名词时，通常只变后一个名词:
如:boy student---boy students; apple tree -- apple trees等
*不可数名词的量化:
通常不可数名词没有复数形式，不能用a/an修饰，且不能用数词直接修饰。不可数名词作主语时，谓语动词通常用单数
注意:不可数名词的量化
具体的量:数词+表示数量的名词+of+不可数名词;
如:a piece of paper一张纸;three kilos of rice三公斤大米
大概的量:表示量的限定词+不可数名词(用 some, much, little, a little, a lot of等表示);
如:some water一些水; a lot of money 许多钱

chicken (可数)“小鸡”(不可数)“鸡肉”
