Is she your mother?含有be动词的句子,在改为一般疑问句时,首先提前be动词,主语是第三人称,不需要变化。同时,物主代词也要变化,如:my改为your等。
否定句:She is not my mother
疑问句:—Is she your mother?
—Yes,she is./No,she isn't.
陈述句变一般疑问句的规则
将陈述句变为一般疑问句应遵循:一提,二改,三帮,四问号。
一提:如果一个句子中含有be动词(am, is, are,)或情态动词can, must,的时候,变一般疑问句时
将他们提到句首。
She is a new student. (一般疑问句)
Is she a new student?
二改:改大小写,改人称
I—改为you we---改为you our---改为your my----改为your
ours—改为yours.
She is my friend. (变为一般疑问句)
Is she your friend? 肯定回答:Yes, she is. 否定回答:No, she isn’t.
三帮:如果一个句子中没有be动词和情态动词,应该借助于三D来帮助。(do, does, did)且后面的动词用原形。
