问题描述：
I looked out and found the ground ____ with white snow
A.covered B.is covered
为什么选A．
而不是B被动语态呢?
答
选a 是因为 covered是作为一个 宾语的 补足语 出现的 分开来说就是i looked out and found the ground, the ground is covered with white snow.那么合并成一个句子就是 原句了 明白了吗？
答
一句话中不能同时出现两个谓语“looked”是这句话的谓语，因此不能选B
A是用过去分词的形式作后置定语，表示被动的含义
答
A 是find＋宾语＋宾语补足语
B 如果是was也可,可以认为I looked out and found （that） the ground was covered with white snow.
但是选项用的时态不对
答
the ground 是宾语,covered是分词修饰宾语.若选B就是两个句子了
I looked out and found the ground.The ground is covered with white snow.
