The teacher suggested the dictionary at once.
A. be referred to be bought
B. be referred to being bought
C. referred to be bought
D. referred to being bought

A. be referred to be boughtB. be referred to being bought (答案→)C. referred to be boughtD. referred to being bought解析：这题考查过去分词做定语和虚拟语气的用法：referred to是过去分词做定语，修饰the dictionary，又因为suggest表示“建议”时，宾语从句用sb （should） do的虚拟语气，选C。

和我的回答一样，看来我也对了
