Grammar Focus Read the following sentences and find out the common features. 含有情态动词的被动语态的结构为： 情态动词+ be +及物动词的过去分词; 变为否定句时只需要在情态动词后加not Tang原创课件,请勿侵权！ 小红书/抖音：Tang原创课件 淘宝：Tang原创课件 1.定义 含情态动词的被动语态用来说明某个被动性动作所反映出的感情和态度。常见情态动词有：can, may, need , must, should等。 含情态动词的被动语态 2.构成：情态动词+be+过去分词 eg:镇上需要种更多的树。 More trees should be planted in the town. 句式 结构 示例 肯定句 主语+情态动词+be+及物动词的过去分词(+by…) Teenagers should be allowed to go shopping. 否定句 主语+情态动词+not+be+及物动词的过去分词(+by…) The word can’t be used in this sentence. 一般疑问句 情态动词+主语+be+及物动词的过去分词(+by…)? Must the work be finished today? 特殊疑问句 特殊疑问词+情态动词+主语+be+及物动词的过去分词(+by…)？ Who should be asked for help? 3.句式 e.g. Many trees should be planted in the mountains. This book can be taken home. This problem can’t be worked out very easily. Must the work be finished at once? 【拓展】 “动词+名词+介词”构成的短语动词(如take care of, pay attention to等)变为被动句时，通常把整个短语当作一个及物动词来处理。 e.g. You should pay attention to your health. →Your health should be paid attention to. 含有情态动词的主动句变为被动句时，有如下步骤： （1）把主动句的宾语变为被动句的主语； （2）主动句中的谓语变为“情态动词 + be + 及物动词的过去分词”； （3）主动句的主语在被动句中变为by的宾语； （4）其他成分不变。 主动句：We should plant trees in spring. 被动句：Trees should be planted in spring. 4.含有情态动词的主动句与被动句之间的转换 将下面三个句子改写成被动语态。 1. He cleans his bedroom every day. 2. He cleaned his bedroom yesterday. 3. He should clean his bedroom in the morning. ______________________________________ His bedroom is cleaned by him every day. His bedroom was cleaned by him yesterday. ______________________________________ ______________________________________ His bedroom should be cleaned by him in the morning. 一般疑问句: 直接将被动语态的陈述句中的情态动词提前。 eg:Must this task be finished at once?这项任务必须立即完成吗？ 注意: 含情态动词的被动语态的一般疑问句的回答，应保留原情态动词，但must表“必须”时，其否定回答应用needn’t；need表“必要”时，其肯定回答应用must。 如： 我的练习本必须现在上交吗？ — Must my exercise book be handed in now? 是的，必须现在上交。/ 不，不必现在上交。 — Yes, it must. / No, it needn’t. 5.句式变换 5.句式变换 否定句：在情态动词后面加上not或never即可，但must表“必要”时 否定式为needn’t。 eg:这项任务没必要立即完成。 This task needn’t be finished at once. 特殊疑问句：由特殊疑问词加上被动语态的一般疑问句构成。 eg: 这项任务必须在什么时候完成？ When must this task be finished? 反意疑问句：借助情态动词构成附加疑问部分。如： eg:这座桥明年能建成，是吗？ This bridge can be built next year, can’t it?
