单项选择题
We hadn’t realized that there would be a power cut so we were astonished when the whole house was () into darkness.
A. dropped
B. dived
C. drowned
D. plunged
答案
参考答案：D
解析：
drop“落下；失落；滴下”；dive“潜水；跳水；俯冲”，此词是个不及物动词，不能用于被动语态，所以不能选；drown“淹没；淹死”，一般指人溺水；plunge“(使)投入；(使)陷入”，一般与into连用，指陷入某种状态，如：plunge a country into war“使一国陷入战争(状态)”。所以根据题意应选D。
