问题
选择题
The third women’ s conference ______ in the USA this summer talked about women’s rights in the developing countries.
A．to be sponsored
B．sponsoring
C．sponsored
D．was sponsored
答案
答案：C
sponsor用作及物动词，意思为“发起；举办；主办”， conference与sponsor为被动关系，根据句子的时态又知这是一个完成的动作，所以用过去分词作后置定语，相当于定语从句that was sponsored。若选D项构成定语从句，需在was sponsored前加上that。
