单选题 A UN official said that aid programs would be ______ until there was adequate protection for relief convoy.

A、 depended
B、 suspended
C、 postponed
D、 expended

【正确答案】 B

【答案解析】[解析] 本题空格处是说援助计划将被延缓。B项suspended“延缓”符合题意，如：We suspended the building work during the rain．下雨天我们中断了建筑工作。其他三项depended“依靠，依赖”：postponed“推迟，使延期”：expended“花费，消耗”都不正确。
