Question

Film has a much shorter history, especially when _____ such art forms as music and painting.

A．having compared with	B．comparing with
C．compare with	D．compared with

Answer 1

D

試題分析：考查狀語從句的省略，英語中當(dāng)主從句的主語一致的時候，可以省略從句的主語和be動詞，When compared="when" film is compared.句意：電影的歷史更短，尤其是和音樂和繪畫這樣的藝術(shù)形式相比。選D。
點評：如果主句的主語和從句的主語一致，且狀語從句的謂語動詞中有 be 動詞，從句的主語連同be 可一起省略，該類狀語從句多為時間、地點、條件、方式或讓步等，連詞為when, while, though, if, unless, although, as if 等，后面通常接分詞、不定式、形容詞、名詞等。
