问题 In my opinion, you can widen the______of these improvements through your active participation.

选项 A、measure
B、volume
C、range
D、scope

答案D

解析 scope“范围”,指人或物的适用性或特定的极限,如:This subject is not within the scope of our investigation.“这个问题不属于我们调查研究的范围。”我们常说wid—en(enlarge,extend,broaden)the scope of…“扩大……的范围”;narrow the scope of…“缩小……的范围”;within(beyond,outside)the scope of…“在(超出)……的范围。”measure“度量,测量”,复数形式的意思是“措施,办法”,如:take sb.’s measure“给某人量尺寸”,The normal measure of life is 70 years.“人的正常寿命是70岁。”adopt/take measures“采取措施”。volume“体积,容积,容量”,如:The vol—ume of water confined by the dam is tremendous. “这个水坝的蓄水量是非常大的”。range“范围,距离,领域”,如:the range of ages“年龄范围”,vocal range“音域”,the average daily range of temperature“每日平均温差”。range常指具体的范围,而scope可以用来指抽象的范围。句中improvement是抽象的,所以选scope合适。
