Neil live in a town 15 miles from London.how far is it from Neil's home to London?后面这个问句中的

不可,去掉it就没有主语了.how far is Neil's home from London?how far is Neil's home to London?这么说吧，原句how far is it from Neil's home to London?中，from Neil's home to London是用来解释it的，it是代词，代指from Neil's home to London的这段距离。how far is it from Neil's home to London?可以分为两部分，how far is it 和from Neil's home to London，理解为它有多远呢？从Neil家到伦敦。但是这句话也可以这样说how far is Neil's home to London?从Neil家到伦敦有多远，比较简单而已。
