Question

The decline in moral standards has at last captured the attention of average Americans.
standards不是复数吗？为什么还用has?

Answer 1

HAS 的主语 THE DECLINE， DECLINE 不可数， 所以用HAS

Answer 2

这句话的翻译是：道德标准的下降最终还是引起了美国普通民众的关注。
has 是指的THE DECLINE说的，与standards是否为单复数无关。
也就是The decline has at last captured the attention of average Americans.本回答被提问者和网友采纳
