问题 The high prices for corn—while driving hunger in Africa—have encouraged other farmers to______land from wheat, soybeans, or even pasture to corn production.

选项 A、turn over
B、turn on
C、turn up
D、turn around

答案A

解析 考查动词短语辨析。turn around表示“回转,转向.转身,扭转”;turn over表示“(底朝上的)翻转,旋转,思考,移交等”,此处指“翻地”;turn on意为“开启,变得兴奋,突然装出,开始”。turn up表示“找到,出现,突然发生”。句意为“高涨的玉米价格在催生非洲的饥荒的同时,促使更多农场主在自己原本种植小麦、大豆甚至牧草的土地上种玉米”。故选A。
