问题 About 75 percent of all cadmium is used for cadmium plating of metals are easily corroded such as iron and steel.
选项 A、metals easily corroded
B、corroded metals easily
C、corroded easily metals
D、easily corroded metals
答案 D
解析 本题重点考查of-phrase的用法。画线部分是of-phrase中的一部分，但却出现了主谓结构，这是明显的错误。of-phrase中一般只应该出现名词或名词词组。四个选项中首先可以排除A和B选项，因为从逻辑关系看，such as后面应该紧跟名词或代词。C选项中副词easily放在了形容词corroded的后面，所以也不能选。故选D，adv．+adj. +n. 后接such as，语义上形成了连贯。
