问题 However, nothing has ever equaled the______and speed with which the human species is altering the physical and chemical world and demolishing the environment.

选项 A、concern
B、determination
C、carelessness
D、magnitude

答案D

解析 本题考查名词辨析。根据空格后的and speed判断,空格处所填词应与speed并列,结合选项,magnitude(程度,规模)符合语义,故答案为[D]项。concern意为“关心,担心”。determination意为“决心,确定”。carelessness意为“疏忽,缺乏考虑;无忧无虑”。
