选择题
The factory used 65 percent of the raw materials, the rest of which _____ saved for other purposes.
A．is
B．are
C．was
D．were
答案
答案：D
题目分析：考查主谓一致，定语从句的主语是the rest of which，which指代the raw materials，谓语是复数，而且这句话是过去时，用were。句意;工厂使用65%的原材料，其余的省下来做其他用途。选D。
点评：the rest of/most of/half of+名词，谓语都是要和名词保持一致的。
