Thank you!!

Answer 1

1）the same +名词+as +从句，从句中有省略情况，as为连词
如 I want to buy the same as you did
2）the same +名词+with+宾语，因为with是介词，
如 I want to buy the same with yours（=your book）
3）the same +名词+that 定语从句，其中that指代的先行词和the same 后面的是一样的
如 the book is the same one that you bought yesterday。
这本书就是我昨天买的书。
ps：您的那几个例子，都是有点瑕疵的。

Answer 2

Q1这两题意思差不多吗?
1.This is the same book as that.
2.This is the same book as the book.
解释：1，首先THE SAMA...AS一般不这么用，一般THE SAME AS 用作定语的短语较多，而这句话THE SAME AS 明显是表语
2中，与一句同样是不规范说法。不过有的老师不一定会说错。只是英国人不这么用。这属于习惯问题。
THE BOOK IS THE SAME AS THAT BOOK正解

Q2.这题有语法错误的地方吗?
This is the same as the book.
语法看似无错误。但和Q1相同，THE SAME AS用法不规范。并且THIS 所指代的东西，未说明。
THE BOOK IS THE SAME AS THAT BOOK正解
Q3.这题语法有错误的地方吗?
I want to buy the same as yours.
BUY 后缺少宾语。BUY为及物动词。其后必有宾语才可构成完整句子。
vt 和vi的区别就不用我解释了吧
1L说的别听。只要有宾语THE SAME AS 没问题，而且他自己还缺宾语
Q4.这题语法有错误地方吗?
The book is the same as that.
错误相同。THE SAME AS 不可用做表语
例子有瑕疵没错，但不能说一定是错误的。如果你是初中的不一定会算你错。但如果你是高中的就一定会扣分了，记住语感很重要！
