1.hear sb(sth) do sth
听到某人(某物)做某事
所以是heared the doorbell ring,用动词原型
2.不能生搬硬套.
如果是这样,你的用法就没有错：
He didn't arrive home until eight o'clock last night.
本题意思是：他到家的时候,还不到8点.
主语是we ,we heard sth ring,若bell 做主语用rings
it was not until 是直到，才
不与yet 连用
hear sb do sth 所以是D
not...until 直到...才
句中是还没到八点他就回来了 所以选择B
