she doesn't have sisters.Her mother doesn't have sisters,too

问题描述:

she doesn't have sisters.Her mother doesn't have sisters,too
怎么改?
前半句 为什么没有姐妹 说的是 doesn't have sisters sister后为什么有s?

too 改成 either否定句里的 ”也是“ 用 either -------------------------have no 加名词,用单数don't/ doesn't have (any) 加名词 用复数 也就是说 I have no sister = I don't have (any) sisters....
