问题 The secretary worked late into the night, ______ a long speech for the president.

选项 A、to prepare
B、preparing
C、prepared
D、was preparing

答案 B

解析 在此句中,现在分词"preparing"作伴随状语。A项是不定式,可以做目的状语,但目的状语前不用逗号。C、D项属语法错误。例如:Kelley was busy in the kitchen,helping her Mum with the dishes. (凯利在厨房里忙碌着,帮她妈妈准备饭菜。)
