Question

英语单项 求教
Hard as the fire was_____,the firefighters didn't withdraw．
A controlled B．to control C．to be controlled D．controlling
我觉得应该选择“A” 但是 答案是“B” 为什么呢

Answer 1

答案的确是B.加了两个单词,你就明白了：
Hard as the fire was FOR THEM to control,the firefighters didn't withdraw．
THEM == the firefighters .
语法结构：
something is hard (for sb.) to do
再不明白,就没有办法了.
