This decreases the device thickness and depletion voltage and ______ reduces material quality requirements and cost of the detector material.
 
【正确答案】 A
【答案解析】 形容词词义辨析。分析句意可知前后是因果关系,所以选择consequently“因而,所以”。continuously意为“不断地,持续地”,指某事连续发生,有始有终且其过程毫无停顿;consistently意为“一贯地,始终如一地”;constantly意为“不变地,坚持不懈地”,指以同样的方式不断地出现,即习惯性地重复。
