解析 C。“Beaker”是烧杯;“Test tube”是试管;“Graduated cylinder”是量筒,用于测量液体体积;“Flask”是烧瓶。正确答案是 C,因为只有量筒是专门用来测量液体体积的。涉及的词汇有 beaker、test tube、graduated cylinder、flask,语法上本题是简单的特殊疑问句,考查对实验仪器名称的理解。
试题来源: 解析 C。选项 A“Test tube”是试管,主要用于少量物质的反应等,不能测量液体体积。选项 B“Beaker”是烧杯,通常用于盛装液体等,也不能准确测量体积。选项 C“Graduated cylinder”是量筒,可以用来测量液体体积。选项 D“Flask”是烧瓶,用于反应等,不是测量体积的仪器。
