考题5：[无锡] UNICEF, part of the United Nations, _____ in Europe in 1946 after World War II.
A. set up B. was set up C. took up D. was taken up
【点拨】set up 建立；take up 占据，占用。根据“in Europe in 1946 after World War II”可知这是联合国儿童基金会的成立时间，因此应用set up 来表示“成立”，且句子应用一般过去时。主语为UNICEF，与动词短语set up 存在逻辑上的被动关系，因此应用被动语态。
B
（2）含双宾语的主动结构变为被动结构时，既可将间接宾语转化为主语，也可以将直接宾语转化为主语。
She gave the little girl some flowers．她给了那个小女孩一些花。→ The little girl was given some flowers by her.
（将间接宾语转化为主语，则保留直接宾语）
They bought the children many good books.
他们给那些孩子买了许多好书。
