The children stood on the pavement,______.
A. watching the buses coming and going
B. watched the buses coming and going
C. when watched the buses coming and going
D. when to watch the buses coming and going
题目解答
答案
A. watching the buses coming and going
解析
本题考查分词短语作伴随状语的用法。关键点在于判断句子中主语与动词之间的逻辑关系,以及分词形式的选择。
- 核心思路:主句中的主语(children)与空格处的动词(watch)之间是主动关系,且动作与主句的“stood”同时发生,因此需用现在分词形式作伴随状语。
- 干扰项排除:选项B、C、D因时态、结构或逻辑关系错误被排除。
选项分析
A. watching the buses coming and going
- 现在分词形式正确,表示“观看”这一动作与“站着”同时发生,且主语children与watch为主动关系。
- 语法功能:作伴随状语,补充说明主句动作的状态。
B. watched the buses coming and going
- 过去式与主句时态(stood)一致,但缺少连词连接,无法构成独立分句,结构错误。
C. when watched the buses coming and going
- when引导时间状语从句时,需完整主谓结构(如“when they watched”),但选项缺少主语,结构不完整。
D. when to watch the buses coming and going
- when to watch是不定式结构,无法与主句形成逻辑上的时间关系,意义不通。
