书上说先行词前有no,all,few,any,little等修饰物时,关系代词不用which,只用that

书上说先行词前有no,all,few,any,little等修饰物时,关系代词不用which,只用that 先行词是不定代词或者先行词被不定代词所修饰时,关系代词通常只用that,不用which.请问,此时that可以省略吗? 先行词nothing something 不定代词or little much修饰或被all every few any 定语从句,只用that不用which的情况中,当先行词是不定代词或者被不定代词修饰时,用that,不用which.这些不 a little a few修饰先行词,关系代词要用that吗? 先行词被序数词、形容词最高级、 the only,the very,the last等修饰时,关系代词通常只用that, (1)先行词是不定代词或者先行词被不定代词所修饰时, 关系代词通常只用that, 当名词前有many,much,few,little等词修饰时,用so,不用such,这个我能看懂.但还有的书上说： THE ONLY THE VERY ANY FEW LITTLE NO ALL 也是不定代词么 为什么先行词为all,everything,anything,nothing,no等不定代词时不能用which 用tha 我的一本书上说：“如果定语从句修饰的地点或时间名词在句中作主语或宾语,这是要用关系代词that或which,而不用whe 被the latest修饰的先行词用THAT作关系代词还是WHICH （定语从句）
