based on a true story 是電影制作的一種途徑,而不是目的.
D選項(xiàng)不定式引導(dǎo)的是目的,顯然不對(duì).能在詳細(xì)些嘛這里based on a true story是作定語修飾the film。還原為：the film was based on a true story。the film was made。組合：the film（which/that was based on a true story） was made.組合后發(fā)現(xiàn)主句和從句的謂語部分相同，那么從句的謂語可以省去。變?yōu)閠he film based on a true story was made.再把定語從句的位置調(diào)到后面即得到原題。
