题目内容
13.The traffic lights arecontrolled(控制) by a central computer.分析 交通灯是由一台中央计算机控制的.
解答 答案:controlled 根据 The traffic lights are____(控制) by a central computer.可知这句话的主语是The traffic lights,是动作的承受着,它和动词control构成被动关系,所以应该用被动语态.被动语态的构成:助动词be+及物动词的过去分词.故填:controlled.
点评 主要考查被动语态,当句子的主语是动作的承受者时,应该用被动语态,本题考查的是一般现在时态的被动语态.一定注意其构成形式,被动语态的构成:助动词be+及物动词的过去分词.
