1、表有生命的东西(人或动物)的名词所有格,一般在名词后加“’s”。如:Mike’s bag, Children’s Day, my brother’s room, women’s rights…
注意:1)名词复数的词尾是-s或-es,它的所有格只在词后加“s”。如:Teachers’        Day, the workers’ rest-home(工人疗养院),the students’reading-room

4、“of词组+所有格”的用法:
在表示所属物的名词前有冠词、数词、不定代词或指示代词(如:a, two, some, a few, this, that, these, those等)时,常用“of词组+所有格”的形式来表示所有关系。如:
a friend of my father’s 我父亲的一位朋友。
some inventions of Edison’s 爱迪生的一些发明
those exercise-books of the students’ 学生们的那些练习本。
三、主谓一致Agreement
知识要点:
在英语的句子中,谓语动词的形式应与主语的人称和数保持一致。如何判定,则要看句子的意思。多数情况下,根据句子的主语形式就能判定,但有的则要看整句的意思,及强调的内容。下面我们就常用的、易混的几种情况作一下解释。
1、以单数名词或代词、不定式、动名词短语或从句作主语时,谓语动词要用单数形式。如:
1)The book is on the table.
2)He is reading English.
3)To work hard is necessary.(It is necessary to work hard.)
4)How you get there is a problem.
2、复数主语跟复数动词。如:Children like to play toys.
3、在倒装句中,动词的数应和它后面的主语的数一致。如以here,there 开头,be 动词与后面第一个名词一致。如:
1)There is a dog near the door.
2)There were no schools in this area before liberation.
3)Here comes the bus.
4)On the wall were two famous paintings.
5)Here is Mr Brown and his children.
4、and连接两个或两个以上的并列主语时,谓语动词用复数。如果主语后跟有with, together with, except, but, perhaps , like, including, as well as, no less than, more than, rather than等引起的短语,谓语动词仍与短语前的主语的形式保持一致。如:
1)Jane, Mary and I are good friends.
2)He and my father work in the same factory.
3)His sister, no less than you, is wrong.
