补充题250_#135

135. The brain is something of a stimulus reduction system, a means to reduce, in order to comprehend, the nearly infinite amount of stimuli that reach the senses at any given moment.

(A) a means to reduce, in order to comprehend, the nearly infinite amount

(B) a means to reduce, in order to comprehend, the nearly infinite number

(C) the means of reducing for comprehending the nearly infinite number

(D) the means that reduces, in order to comprehend, the nearly infinite amount

(E) the means for reducing in order to comprehend the nearly infinite amount

正确为B。 想请问为什么不用"infinite amount of "而用"infinite number of"呢？

因为 stimuli 是 stimulus的复数形式.
