情态动词的被动语态
情态动词的被动语态【概念】（1）情态动词的被动语态：含情态动词的被动语态说明某个被动性动作所反映出的感情和态度．初中阶段学习可用于被动语态的情态动词有can，may，must，need，should等，分别表示"能够被…；可以被…；必须被…；应该被…"等．（2）被动语态：被动语态（passive voice）是动词的一种形式，用以说明主语与谓语动词之间的关系．英语的语态共有两种：主动语态和被动语态．主动语态表示主语是动作的执行者，被动语态表示主语是动作的承受者．被动语态是动词的一种特殊形式，一般来说，只有需要动作对象的及物动词才有被动语态．汉语往往用"被"、"受"、"给"等被动词来表示被动意义．被动语态由"助动词be+及物动词的过去分词"构成．（3）及物动词：在英语中按动词后可否直接跟宾语，可以把动词分成两种：及物动词与不及物动词．字典里词后标有vt．的就是及物动词，字典里词后标有vi．的就是不及物动词．不及物动词后不能直接跟有动作的对象（即宾语），若要跟宾语，必须先在其后添加上某个介词，如to，of，at后方可跟上宾语．及物动词可直接跟宾语．【结构】含情态动词的被动语态结构形式：主语+情态动词+be+及物动词的过去分词．①主语+情态动词+be+（by+宾语），其中by意为"被…；由…"，表动作的执行者．如：The library must be kept quiet by us．我们必须保持图书馆安静．②含情态动词的疑问句、否定句的变化均需借助于情态动词完成．如：Magazines can be taken out of the reading room．（肯定式）Magazines can't be taken out of the reading room．（否定式）Can magazines be taken out of the reading room？（疑问式）Yes，they can．/No，they can't．。
