英语语法问题
The police found （that）the house had beenbroken into and a lot of things stolen.that可省略吗?还有stolen前为啥不加be,不是被偷吗?

Answer 1

完整句式应该是：
The police found that the house had been broken into and a lot of things were stolen.
that引导定语从句这里可以省略；
stolen前不加be是因为这里用了过去分词做状语表示状态----东西被偷的状态.
下面有具体用法：
1．过去分词作时间状语相当于一个时间状语从句.例如：
Asked (When he was asked) what had happened,he lowered his head.
当他被问问题的时候,他低下了头.
2．过去分词作原因状语相当于一个原因状语从句.例如：
Frightened (=Because / As she was frightened) by the tiger,the girl didn't dare to sleep alone.
因为害怕老虎,这个女孩不敢单独睡觉.
3．过去分词作条件状语相当于一个条件状语从句.例如：
Grown (If these seeds are grown) in rich soil,these seeds can grow fast.
如果种在肥沃的土壤里,这些种子能长得很快.
