Question

9．他发现自己的房间乱七八糟．
He found his room in a mess．

Answer 1

分析 He found his room in a mess．

解答 答案：He found his room in a mess．这里是说过去的事情用一般过去时，发现某物怎么样用find+宾语+宾补，主语he，find的过去式found，宾语his room，用介词短语in a mess 混乱的，作为宾语补足语，故答案是He found his room in a mess．

点评 find意为"发现、发觉"作此意解时，其后接宾语+宾补（分词、形容词、副词、名词、介词短语或to be）．作宾补的动词用现在分词还是过去分词取决于动词同宾语之间的关系．
