Noise suppression in phones can play an important role in making cellphone networks more efficient, since when sounds that are________ to the meaningful signal are transmitted, precious network bandwidth is wasted.
A. unsuitable
B. detrimental
C. irrelevant
D. confined
E. limited
F. extraneous
选项
答案
C,F
解析
-方程等号:when,同义重复。
-强词和对应:当传输对于重要信号空格的声音的时候,珍贵的带宽被浪费了,强词是wasted,指向空格,根据when同义重复,空格应填入wasted的同义词。选项里有两组同义词,第一组是irrelevant与extraneous不重要的,第二组是confined与limited有限的,答案选择CF。其他选项,unsuitable不合适的,detrimental有害的。
