问题 Corn was not known in Europe until Columbus______(发现玉米被种植) in Cuba.
选项
答案 found it being cultivated
解析 “玉米被种植”用the corn was cultivated表达。“发现”用find表达，常采用find sth．doing的形式。此处是被动，所以要用现在分词的被动式being cultivated。为避免词汇的重复，此处the corn可由it指代。最后判断此处的时态，从was，until可推断出此处的谓语动词为一般过去时，故答案为found it being cultivated。
