A．is short for

B．is lack in

C．are short of

D．are lack of

Answer 1

B

试题分析：考查固定词组，is short for意思“是…缩写”，is lack in意思“缺乏”，are short of意思“缺乏”，由which做主语，可以判断句子的谓语是单数还是复数，是单数，首先排除C、D，根据意思“联合国教科文租住是一个国际组织，它缺乏国际教育、科学、文化的组织”,所以选B
点评：句子UNESO is an international organization ,which…是由关系代词which引导的非限制性定语从句，（用逗号和前面的分句隔开）。
