Some day software will translate both written and spoken language so well that the need for any common second language could _______ .

A descend B decline C deteriorate D depress

参考答案:

B选[B]。可以很快排除[C]deteriorate:变坏;和[D]depress,萧条,贬值。[A]descend和[B]decline都表示"下跌,下降"的意思,但descend一般用来指事物从一个较高的位置上落到较低的位置上,表示空间方位的变化,而decline的用法比要descend广,既可指空间位置的变化,又可指其他方面,如需求数量的减少。
