Languagepoints

含有be动词的一般疑问句的构成及其答语

结构Be动词（Am/Is/Are）+主语+其他？↗

肯定回答Yes,主语（人称代词）+be动词（am/is/are）.↘

否定回答No,主语（人称代词)+be动词（am/is/are）+not.↘

一般疑问句主语是this,that,these或those，回答时用it指代this或that；用they指代these或those。

含be动词的肯定句变一般疑问句

“一提、二变、三问号”

一提：将be动词提到句首，且首字母大写。

二变：把原主语的首字母变成小写；如果原主语为第一人称，则应把第一人称变为第二人称，be动词也要作出相应的变化；如果有形容词性物主代词my或our，也应改为your。

三问号：将句末的标点符号改为问号。
