she can't be his mother这个句子的反意疑问句应该是什么,是can she还是is she
she can't be his mother这个句子的反意疑问句应该是什么,是can she还是is she
反义疑问句的口诀:前肯后否,前否后肯,前be后be,前无be后加助,时态一致.
所以she can't be his mother,isn't she?
再问: 句子中有情态动词can,前面是否定的,后面是肯定的~是不是句子中有be的后面肯定是用be的吗?即使be前面还有情态动词can~
再答: 纠正:she can't be his mother,is she?(不好意思,疏忽了) 句子中有be的后面肯定是用be,be前面有情态动词can时,can在这里一般都表示推测,所以后面的反义疑问也用be.
