in classroom 3E

二、重点语法

1.一般疑问句

(1)一般疑问句一般翻译为“......吗？”需要对方用yes或no来回答。

(2)结构和答语

①一般疑问句主语为this/that时，答语中主语用it.

②一般疑问句主语为those/these时，答语中主语用they.

③在肯定回答时，主语不能与be动词缩写；否定回答时，be动词常与not缩写，但是am与not不能缩写(No,I’m not.)

2. 物主代词2：名代

(1)物主代词的形式

注意：两种代词形不同，添个s形变名，his,its不用变，my变mine要记清。

(2)用法

形代起形容词的作用，用在名词前，后面必须有名词；                                      This is my book.

名代起名词作用，其作用相当于一个名词，只能单独使用，不加名词；           This book is mine.

名代=形代+名词  This is my book. That is yours.

名代可放在句末，形代不可放句末。

注意：在使用名代时，必须有特定的语言环境，也就是要省略的名词大家已经知道，已经提过。（只有上文提及了某个名词，才会知道名代所指代的事物）

(1)     顺口溜:用形或用名，全凭后决定；有名则用形，无名则用名。
