疑问句?

陈述句如何变成一般疑问句?
一般疑问句的概念
一般疑问句的概念:能用yes或 no回答的问句就叫一般疑问句。
含有be动词的陈述句变一般疑问句的方法
1) 将be动词提至句首
2) 将第一人称变为第二人称,即 I 由 you替换; my由your替换; 相应地am也变为are.
3)将句末标点改为问号
简单归纳即为:一提二改三问号。

名词性物主代词:
在英语中,物主代词是表示所有关系的代词,分为形容词性物主代词(第一单元已学过)和名词性物主代词(本单元所讲)两种。
概念:名词性物主代词也是用来表示所有关系的代词,有人称和数的变化。
第一人称 第二人称 第三人称
单数 mine yours his/hers/its
复数 ours yours theirs
用法:①名词性物主代词在句中能单独使用,后面不能接名词,其作用相当于一个名词,通常在句中作主语、宾语或表语。
②名词性物主代词在作主语时,谓语动词的数应随所指者的数来定。
如:This red pencil is mine.Hers is black.(Hers=her pencil)这支红色的铅笔是我的,她的(铅笔)是黑色的。
These books are his.Yours are over there.(Yours=Your books)这些书是他的,你的(书)在那边。
与形容词性物主代词之间的关系:
名词性物主代词=相应的形容词性物主代词+名词
如:This is my bike.That is yours.(yours=your bike)这是我的自行车,那是你的(自行车)。
