1、 Tom looked at Jenny ,tears___his eyes,and shouted out the words___in his heart for years .
A. filling;having been hidden
B. filled;hidden
C. filling;hidden
D. filled;hiding

答案给的是C，我想知道A为什么不对（不是有时间段“for years”嘛）
有一种说法是：hide 是状态性动词，与其他谓语动词无法比较先后顺序，因而不能使用现在分词的完成被动式。可我觉得hide在A、C选项中是及物动词表“藏匿”不象是状态性动词啊。

2、The book was written in 1946,____the education system has writness ed great changes.
A When 、 B during which 、C since then 、D since whe n
答案给的是D，但是我认为D不对，我想选C

1.
不能用助动词have+过去分词来做定语
这里hidden in his heart是tears的后置定语
但可以说 tears that had hidden...（用定语从句）

2.
如果用Since then的话
前面一句要点上句号。另起一句Since then，the education system has writness ed great changes.
因为The book was written in 1946.是一个完整的句子，后面用非限定性性定语从句.
Since then，...已经是一个新的句子了。
