题目内容
5.We teach young children traffic rules for their safety.Traffic rulesaretaughtto young children for their safety.
分析 --为了安全我们教孩子们交通规则.
--为了安全交通规则被教给孩子们.
解答 答案:are taught.考查被动语态.句意"--为了安全我们教孩子们交通规则.--为了安全交通规则被教给孩子们.",Traffic rules是动作的承受者,因此用被动语态,be动词+done.一般现在时态,主语是复数,因此用be动词的复数are,teach的过去分词是taught.答案是are taught.
点评 被动语态表示主语是动作的承受者,被动语态由"be动词+及物动词的过去分词"构成,be动词的单复数要与主语的单复数保持一致,还要注意过去分词的变法.
