As she ___ the newspaper. Granny ___ asleep.
A. read , was falling
B. was reading; fell
C. was reading, was falling
D. read; fell
题目解答
答案
B. was reading; fell
解析
本题考查过去进行时与一般过去时的搭配使用,关键在于理解as引导的时间状语从句中动作的同时性与先后性。
- as表示“当……时”,若从句动作与主句动作同时发生,通常用过去进行时;若从句动作为背景动作,主句动作是短暂性动作,则从句用过去进行时,主句用一般过去时。
- 本题中,“读报纸”是背景动作,“睡着”是短暂性动作,因此需用was reading(过去进行时)和fell(一般过去时)的搭配。
选项分析
-
选项B(was reading; fell):
- 从句用过去进行时
was reading
,表示“读报纸”是背景动作; - 主句用一般过去时
fell asleep
,表示“睡着”这一短暂动作在此时发生。 - 符合as引导的同时性动作的语境。
- 从句用过去进行时
-
其他选项错误原因:
- A(read; was falling):
read
为一般过去时,无法体现动作的持续性,与fell asleep
的短暂性矛盾。 - C(was reading; was falling):
was falling asleep
表示“正在睡着”,与实际语境“突然睡着”不符。 - D(read; fell):两个动作均为一般过去时,无法体现“读报纸”是背景动作。
- A(read; was falling):
