不，它们不是。含be动词的一般疑问句的结构及其答语不可以缩写成it’sPresentation含be动词的肯定句变一般疑问句，可采用“一提、二变、三问号”的方法。一提：指的是将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；如果有形容词物主代词my，也应改为your。三问号：将句末的标点符号改为问号。Sheisateacher.Issheateacher?IamTony.AreyouTony?Thosearemypens.Arethoseyourpens?Thisisherbook.Isthisherbook?含be动词的肯定句变一般疑问句GrammarFocusIsthisyourpencil?Yes,itis.It’smine./No,itisn’t.It’shers.Isthishisgreenpen?Yes,itis./No,itisn’t.Thebluepenishis.Isthatyourschoolbag?
