名词所有格
概念：
名词所有格表示所属关系，相当于汉语中的“的”。在英语中，有些单数名词词尾加“________”，这种形式称为_____________。
's
名词所有格
构成
类别 构成方法 举例
有生命的单数名词 加“'s” Jack's father
Tom's pen
有生命的复数名词 以s结尾的加“ ' ”；不以s结尾的加“ 's ” the teachers' office
Children's Day
类别 构成方法 举例
表示时间、距离、 国家等的名词 在其后加“ 's ” half an hour's walk
表示共同拥有某物 只在最后一个词后加“ 's ” Mike and John’s desk
类别 构成方法 举例
表示各自拥有某物 每个名词后都加“ 's ” Lily's and Lucy's rooms
无生命的名词 of＋名词 the legs of the desk
注意：
①名词所有格后面跟表示住宅、店铺等的名词时，这些名词习惯上可省略。如：
go to Uncle Wang's 去王叔叔家
at the doctor's 在诊所
②在单词后加's不一定都是所有格形式。如：
My mother's a teacher.(mother's为mother is的缩写，不是所有格) 我妈妈是一位老师。

序数词的变化
概念：
在英语中，表示顺序的词称为序数词。
基数词变序数词口诀：
基变序，有规律，词尾 th莫迟疑；
一二三，特殊记，单词结尾t, d, d；
八减t，九减e，f要把ve替；
ty把y改为i，记住th前还有e。
说明：
①“第一”、“第二”、“第三”分别是 ________，________，________，它们的结尾字母分别是t, d, d。
②eight变成 ________ 时，词尾只加 h，相当于把eight中的t减掉，再加 th。
③nine变成 ________ 时，要去掉e。
④five→_____，twelve→______，都是把ve改为f，再加 th。
first
second
third
eighth
ninth
fifth
twelfth
说明：
⑤表示“整十”以 ty结尾的基数词，变成序数词时，把y改为________，再加 ________。如：twenty→twentieth, thirty→thirtieth
⑥表示“几十几”的基数词(十几除外)变序数词时，只把 ________ 变成序数词即可。
i
eth
个位数
用法：
①序数词的前面一般要加定冠词the，但当名词前已经有了物主代词时，序数词前不再加定冠词the。如：my first book我的第一本书
②序数词可以用来表示顺序、编号等，相当于“名词＋基数词”。如：the fifth lesson＝Lesson Five
注意：在“名词＋基数词”结构中，基数词和名词的首字母都要大写。
