If ____unsolved, the problem of food safety may lead to more serious results.
A.leftB.makingC.remainedD.taking

答案
A
解析
    
试题分析: A剩下,B使,制造;C保留,剩下;D带走。由结构可知此处是非谓语做状语,句子主语problem和动词之间是被动关系,应该用过去分词,故排除B、D选项;而remain是不及物动词,不能用过去分词表示被动,故答案选A。短语“leave+宾语+宾补”表示使某人或者某物处于某种状态。句意:如果食品安全问题留下不去解决,那么它将造成更多的严重后果。
举一反三
