雅思基础语法教材及练习答案
Lesson One ：名词、冠词和代词的用法第一部分：语法讲解一、名词用法讲解1.名词的数：英语中的名词可以分为可数名词(countable noun)和不可数名词（uncountable noun）。
如：“book, pen, cup”都是可数名词。
“furniture, milk, air”都是不可数。
在这里强调一点：英文中名词的可数和不可数是不能按照我们汉语的逻辑思维去理解的。
比如汉语中的“家具”，我们常说：一件家具。
但是英文中“furniture”是不可数的。
还需要注意的一点是，英语中有很多的名词既可以用作不可数名词也可以用作可数名词，只不过此时词义往往不同。
如：There is plenty of room for everyone to sit down in this room. 这房间有足够的空间让每个人坐下。
（第一个room作为空间是不可数的；第二个room作为房间是可数名词）b.以o结尾的名词，直接加-s,如：photo-photos, bamboo-bamboosc.以f 或者fe结尾，直接加-s,如：belief-beliefs, cliff-cliffs可数名词复数的不规则变化：1）变换元音或者加后缀如：tooth-teeth （牙齿）foot-feet （脚）mouse-mice （老鼠）woman-women（妇女）ox-oxen（公牛）child-children（孩子）2）单复同形如：cattle （牛）Chinese （中国人）sheeep （羊）reindeer （驯鹿）means （方法）3）外来语的复数形式拉丁语：datum-data （数据）medium-media（媒介）希腊语：crisis-crises（危机）phenomenon-phenomena（形象）不可数名词的数：不可数名词通常没有复数形式，但可以借助单位词来表示一定的数量。
如：a piece of paper一张纸 a slice of meat一片肉a fit of cough一阵咳嗽 a ripple of laughter一阵笑声2. 名词的所有格名词的所有格有两种形式：一是在名词后面加’s的形式，二是在介词of后加上名词的形式。
