问题 The combination of lenses in a compound microscope makes possible greater amplification than can be achieved with a single lens.
选项 A、management
B、magnificence
C、magnetism
D、magnification
答案D
解析 amplification的意思是“扩大”。四个选项中，A项management表示“经营，管理，处理，操纵，驾驶，手段”，B项magnificence表示“华丽，富丽堂皇”，C项magnetism表示“磁，磁力，吸引力，磁学”，D项magnification表示“扩大，放大倍率”。本题是说由多个透镜组合起来的显微镜可能比单片显微镜放大很多倍。因此D项为正确答案。
