it is reported that a film (direted ) by an unknown directorwon the firse prize in this film festival 这里的direted有被动的意思,但为什么没有be动词呢?不是be+p.p来充当被动语态的吗 PS开头的is是修饰reported的吧 英语

【答案】 It is reported that a film directed by an unknown director won the first prize in this film festival.
这个it是形式主语,指后边的that从句
directed by...修饰film,是做后置定语,不是谓语,因为从句中有动词了（won）.一句话只能由一个动词作谓语,其他的动词只能做非谓语动词,或者降级为从句,或者加连词并列.
