含有情态动词的被动语态“闯五关”
含有情态动词的被动语态“闯五关”作者：舒安江来源：《中学生英语·九年级》2008年第10期含有情态动词的被动语态是情态动词和被动语态中的重要内容，也是中考的重要考点，学习时应闯过以下几关：【第一关】概念关英语动词有两种语态,即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。
【第二关】构成关被动语态由“助动词be+及物动词的过去分词”构成。
含有情态动词的被动语态，其结构为“情态动词+助动词be+及物动词的过去分词”。
例如：Teenagers should be allowed to go out with their friends. 应该允许青少年和朋友们外出。
【第三关】用法关1. 不知道或没有必要说出动作的执行者是谁或者大家都清楚动作的执行者是谁时,常用被动语态。
例如：The children should be allowed to go to the movies with friends on Friday nights. 孩子们应当被允许星期五晚上和朋友们一起去看电影。
2. 强调动作的承受者,而不是动作的执行者时,常用被动语态。
例如：Tables can be made of stone. 桌子可由石头做成。
【第四关】句式关含有情态动词的被动语态变为否定句时，应在情态动词后面加not；变为一般疑问句时，应将情态动词移到句首。
例如：Waste paper should not be thrown here. 废纸不应该扔在这里。
Must the trees be watered now? 这些树必须现在浇水吗？【第五关】变法关含有情态动词的主动语态变为被动语态时,要把主动语态中的宾语变为被动语态中的主语;主动语态中的谓语动词变为“情态动词+助动词be+过去分词”; 主动语态中的主语变为介词by 的宾语,放在句尾(如果不强调动作的执行者, by短语常可省略)。
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．。
常见的情态动词的被动语态怎么构成？

情态动词被动语态结构
情态动词被动语态结构情态动词被动语态结构是一种特定形式的语法，它包含情态动词、助动词和及物动词。
它表示动作或存在的可能性受到外部力量的影响，无论外部力量是什么。
通常，情态动词被动语态表示一种不确定的事实，而不是一种可能实际发生的事件或动作。
常见的情态动词被动语态结构有 should、could、would、might、must、shall等。

下面是几个例子：1. He should be advised to stay away.2. The government must be held accountable.3. The new technology could be used to improve efficiency.4. This problem might be solved quickly.5. The package should be delivered on time.6. The meeting shall be cancelled.上述例子中，所有的情态动词都以助动词be开头，然后接及物动词的被动语态形式：advis（ed）、held（accountable）,used（to improve）, solved（quickly）,delivered（on time）, cancelled。
这反映了动作（或存在）的可能性受到外部力量的影响。
另外，情态动词被动语态结构还可以用来表示一种责任和责任的概念，即某人应该做某事，或者某事应该被某人做。
例如：7. The problem needs to be addressed promptly.8. The student should be rewarded for their efforts.9. Everyone should be treated with respect.10. The issue must be discussed thoroughly.上面的情态动词被动语态表示了某事应该有某人来做，或者某人有责任去做某事，或者某件事情必须被完全讨论。
