Question

正确答案是什么？为什么？

“The vase completely broken is a precious souvenir” has all the possible meaning except
A. The vase that has been completely broken is a precious souvenir
B. The vase is completely broken is a precious souvenir
C. The vase was completely broken is a precious souvenir
D. The vase that had been completely broken is a precious souvenir

Answer 1

C. 语法错误，The vase was completely broken 是被动语态，有完整的句型结构（就是一个句子），后面有直接+is a precious souvenir，又构成一个“系动词+表语”结构，这样是不可以的。句型错误。

Answer 2

你好

答案是B
句子
The vase completely broken is a precious souvenir （重点是broken，过去分词做后置定语，相当于一个定语从句）

分解成俩句话：
The vase is a precious souvenir.（这个用一般现在时无异议）

第二个句子不可是：The vase is completely broken（假设by me ）.因为这个句子的主动式就是
I break the vase. 很简单，一般现在时表示的最基础的意思是经常性的动作，难道你经常会打碎一个花瓶吗？花瓶只能打碎一次。

其它三个句子 A has been broken 可以，已经被打碎
C was completely broken 可以，过去被打碎

D had been completely broken 也是可以的
