是的，你的理解正确
考查状语从句的省略，英语中当主从句的主语一致的时候，可以省略从句的主语和be动词，When compared="when" film is compared.句意：电影的历史更短，尤其是和音乐和绘画这样的艺术形式相比。选D。
如果主句的主语和从句的主语一致，且状语从句的谓语动词中有 be 动词，从句的主语连同be 可一起省略，该类状语从句多为时间、地点、条件、方式或让步等，连词为when, while, though, if, unless, although, as if 等，后面通常接分词、不定式、形容词、名词等
关于如何判断主动被动，翻译出来看就很明显了，另外可以结合某些短语的及物与否来判断主被动，希望帮到你，欢迎不懂继问！追问
是不是主语如果是物，非谓语动词一定是被动，如果主语是人就一定是主动是吗
追答当然不是啦，不要这么理解啊，即使是物做主语，也可以是主动的，举个最简单的例子
总而言之不要主观臆断，多积累，多翻译，语感出来了自然就好了！

英语的被动语态和主动语态在句子中怎样区分？
主动语态和被动语态。
如果主语是动作的执行者，或者是说动作是由主语完成的，要用主动语态；如果主语是动作的承受者，或者是说动作不是由主语而是由其他人完成的，则用被动语态。
被动句子结构：1.一般现在时： be+ v-ed（表示动词的过去分词）2.一般过去时：was/were+ v-ed.3.一般将来时：will be +v-ed.4. 过去将来时：would have been5. 现在进行时：is/am/are being+ v-ed6. 过去进行时：was/were being +v-ed7. 现在完成时：has/have been +v-ed8. 过去完成时：had been +v-ed你就看有没有being/been……+过去分词，有就是被动语态
