1,之所以是定语从句是 that后面的句子修饰all
如果是宾从应该是I'm interested in what you have told me.
（宾从应该是从句部分是整个句子结构中所必不可少的,
而定从是你删掉从句整个句子结构还是完整的
就这个句子来说,你删掉that 后面的从句就变成了I'm interested in all
是个完整的句子）
2 可以
3 很简单,因为where=in which,注意动词搭配,spend+in才完整
原句相当于this is the place in which I spent my childhood
而第二句,visit不用搭配介词in,所以可以直接引导从句

that you told me 修饰的是all
be indicated at 是固定句型
第二句visit后
是要加宾语的，缺少成分，用了which

1,宾语是all ，all作为先行词 that引起的定语从句修饰all，that从句对all有修饰限定作用，如去掉，只影响句子含义而不影响句子结构 但若果是宾语从句 去掉后对结构和含义都会有影响 会造成句子宾语的残缺
上句all that 含义等于what因此 如果句子写成I'm interested in what you have told me.就是what引导的宾语从句

2 可以的 因为定语从句中如果关系代词做介词宾语 而且介词和动词不构成密不可分的动词短语（如look after 即为密不可分，因为分开后含义不是“照顾”）这时可将介词提前和关系代词一起出现 有时候结构相当于变为关系副词 但要注意 介词提前后 不可以用that和who 只用which和whom
3 This is the place where i spent my childhood.这个句子中，spend为及物动词 my childhood做spend的宾语 因此 定语从句主谓宾完整 分析可知 句子缺少状语因此应用表地点关系的关系副词where 此处where=in which
原句即等于：This is the place in which I spent my childhood
This is the place which i visited last summer. 从句中visit为及物动词 后面应当跟有宾语 因此定语从句缺宾语而不缺状语 所以用that/which 由于在句子里 that或是which做宾语 所以还可以省略关系词 直接写：This is the place I visited last summer.

Ps：平时要注意写句子的习惯~ 注意句子第一词首字母大写这些细节
