__for several weeks,the city needed food.
A.As having flooded B.being flooded C.Having been flooded D.To flood

__for several weeks,the city needed food.A.As having flooded B.being flooded C.Having been flooded D.To flood
for several weeks 是完成时的标志,所以答案必为完成时,排除了B、D
但因为city 是被水掩的,所以要用被动.
因此答案是Having been flooded
整句:Having been flooded for several weeks,the city needed food.
已经水淹了几周,这城市需要食物了.

C. Having been flooded
过去分词的完成时态做原因状语,说明the city needed food 的原因。

c

首先,中间有逗号不选A,后面句子是过去式,不选C,D完全不对,句中the city 是主语,只能是被淹,所以选B!

C

你好。答案是C

分词结构表“时间状语”,这个动作发生在needed以前,所以用“完成式”分词。
== AS the city had been flooded for weeks, it needed food.-------这是“时间状语从句”。
