## 一般疑问句 通过主谓倒装可将带有be的陈述句变为一般疑问句.即将be的适当形式移到主语之前,如: ``` is this your ... ? //陈述句是this is your ... this是主语, is是谓语,将主谓倒装变成一般疑问句 yes, it is. //肯定回答 no, it is not //否定回答 ``` ### 功能 询问 ### 构成 be(is,am ,are )动词置于句前. ### 例句1 ``` This is your name. //一般陈述句 ``` ``` Is this your name ? //一般疑问句,将be动词is前置变为一般疑问句. ``` ### 例句2 ``` i am great. ``` ``` Am I great ? ``` ``` Are you great ? ``` ### 例句3 ``` She is pretty. ``` ``` Is she pretty ? ```
