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
结构 be动词 + 主语 +其他？
肯定回答 Yes, 主语 + be动词.
否定回答 No, 主语 + be动词和not的缩写（isn’t/aren’t,特殊：No, I’m not.).
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.)
物主代词2：名代
(1)物主代词的形式
人称 第一人称 第二人称 第三人称
形代 my our your your his/her/its their
名代 mine ours yours yours his/hers/its theirs
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）
顺口溜:用形或用名，全凭后决定；有名则用形，无名则用名。
