Question

_____________ ,they went home,________________.

A．Their work had been finished; singing and laughing

B．They had finished their work; sang and laughed

C．Their work finished; singing and laughing

D．a(chǎn)fter their work finished; singing and laughing

Answer 1

C

試題分析：考查獨立主格結構，分析句子，they went home是簡單句，前面如果沒有連詞，就是獨立主格結構，their work是邏輯主語，后面接非謂語動詞，排除A，B，D項是有連詞after的，所以后面的句子應該是their work had been finished;第二空使用現(xiàn)在分詞做伴隨狀語，是回家的過程中同時做的事情，不是一連串并列動作。不能用sang and laughed ，選C。
點評：當分詞做狀語的時候，如果分詞的邏輯主語與句子主語沒有關系，就在分詞的前面直接加上邏輯主語，形成獨立主格結構，該結構在作用上久相當于一個狀語從句。
