问题 The effect of doubling the width of a beam,______ is to double the load that can be sustained.
选项 A、other factors remain constant
B、other factors remained constant
C、the other factor being constant
D、other factors remaining constant
答案 D
解析 other factors remaining constant 是分词独立主格结构，在句中作伴随情况状语。A、B两项都是完整的句子，虽然在意思上讲得通，但从结构上无法与句中其他成分相连接，即没有关联词作连接手段：C中虽然从结构上可以接受，但在意义上being 用得不够准确。全句译为“在其他情况保持不变的同时将横梁的宽度加大一倍，其结果是横梁的承受力也加大了—倍。”
