单选题 In regard to the patient's sensitive skin, the doctor advised him to limit his ________to the sun.

【正确答案】 D
【答案解析】[解析]近形近义题。[D]exposure意为“暴露”,如much exposure to danger(经历过许多危险事)/a short exposure to sunlight(短暂暴露在阳光下),符合题干语义,故为答案。[A]expansion意为“扩张,膨胀”,如 industrial expansion(工业扩张);[B]exhibition意为“展览,表现”,如an exhibition of bad manners(没礼貌的表现);[C]extension意为“延长,扩展”,如the extension of foreign trade(对外贸易的扩大)。
[句意]鉴于患者敏感的皮肤,医生建议他尽量少暴露在阳光下。
