就是说这个句子:
I discovered him finished his homework. 我发现他已经完成了作业,是否写对了呢?
老师给了我一个例句说只可以用过去分词表状况,譬如:
I discovered him exhausted.真的想不过来了,帮指点一下。
discover可后接动词不定式、目前分词或形容词作宾补,但不接过去分词作宾补。比如:
We discovered the cart to slide down the slope. 大家发现大车沿斜坡滑下来。/ I discovered the boy jumping over the wall. 我发现这男生跳过这堵墙。(摘自王福祯主编《英汉多功能学习词典》p.308) I discovered him to be quite trustworthy.我发现他相当靠谱。(摘自外语教学与研究出版社1997年1月第1版《英汉多功能词典》)
discover 也可后接 that 或者 wh- 从句作宾语,that 可省略。比如:
I discovered she was a good cook. 我发现她非常善于烹饪[做菜]。/ We never discovered how he died. 大家一直不了解他是如何死的。(摘自外语教学与研究出版社1997年1月第1版《英汉多功能词典》)
所以:I discovered him finished his homework.(错误)I discovered he had finished his homework.(正确)
