问题 The doctor took X-rays to rule out the chance of broken bones. The underlined part means______.

选项 A、prevent
B、exclude
C、cancel
D、reject

答案B

解析 词义理解题。原句中rule out意为“排除;不考虑”,而exclude意为“排除(某种可能性);不包括”,两者意思相同,因此选项[B]为答案。prevent意为“阻止;预防”;cancel意为“取消;删去”,用法广泛,多指取消债务、合同、证书、比赛、旅行、计划或约会等;reject意为“拒绝;排斥”,多指由于某物、某事或某行为不能让人满意而被当面直截了当地拒绝。
