句子的变化
陈述句的否定
种类
谓语动词含有be 动词或情态动词
这时直接在be 动词或情态动词后加否定词not 即构成否定句
He is a teacher.
He is not a teacher.
谓语动词是实义动词
这时陈述句的否定要借助于助动词do + not 来构成,
若主语是单数第三人称则用does + not + 动词原形
I like English.
I do not like English.
一般疑问句
种类
谓语动词含有be 动词或情态动词
这时要构成一般疑问句,只需将be 动词或情态动词移到句首。
He is a teacher.
Is he a teacher?
Yes, he is./No, he isn’t. //肯定回答用yes,否定回答用no.
谓语动词是实义动词
这时要借助于助动词do 或does,将do 或does 放在句首。
特殊疑问句
特殊疑问句是在上述一般疑问句的基础上变化而来的,句式:特殊疑问词+一般疑问句或主语的疑问词+谓语部分。
