many a woman is/are

Many a woman 虽然在概念上是表示复数,但 many a 之后的名词总是采用单数形式,故其谓语动词总是用单数,也就是说,这里遵循的是语法一致的原则,而违背概念一致的原则:

1. Many a member has protested against the proposal. (CGEL) 许多成员反对这个提议。

2. Many a man has sacrificed his life for the cause of revolution. 许多人为了革命牺牲了自己的生命。

据此可以毫无困难地判定下列判错题中的错误：

1. There have been $\$frac{\text{many an}}{\text{A}} argument about $\$frac{\text{its}}{\text{C}} proper usage. (TOEFL)

2. Such is the general purport of this legendary superstition, which has inspired many a wild stories in that region. (EPT)
