2.The foreign friends you referred to________looking forward to________around our university. A. are; being shown B. being; being shown C. being; showing D. are; be shown 答案与解析:A 本题考查句子分析的能力及look forward to 的基本用法。本句主语是The foreign friends,you referred to是定语从句,所以谓语动词使用are,构成现在进行时;短语look forward to中的to是介词,用动词-ing形式作其宾语。
