下面5句都是合法句(宾语句比补语句更正式) 1. People found that the world completely changed. 2. People found that the world was completely changed. 3. People found the world [completely changed].(宾补[.]) 把1.2.中that省掉 1a. People found [the world completely changed]. (子句) 2a. People found [the world was completely changed]. (子句) 若was移到completely后,很罕见。
