A radio message was sent across the Atlantic Ocean for the first time in 1901. 知识讲解 一、被动语态的含义及用法 英语动词有两种语态，即主动语态和被动语态。当主语为动作的执行者时，谓语要用主动语态；当主语为动作的承受者时，谓语要用被动语态。如： The bees collect honey. （主动语态，句子的主语 the bees 是动作 collect 的执行者。） Honey is collected by the bees. （被动语态，句子的主语 honey 是动作 collect 的承受者。） 被动语态的构成为“助动词 be + 及物动词的过去分词”。助动词 be 有人称、数和时态的变化。当不知道或没有必要说明动作的执行者，或需要特别强调动作的承受者时，常用被动语态。 二、主动语态变被动语态 步骤 Step 1 定主宾：找到主语与宾语。 Step 2 换主语：把主动语态的宾语变为被动语态的主语。 Step 3 改结构：把谓语动词变成被动结构“助动词 be + 及物动词的过去分词”。 Step 4 加 by sb.（宾格）：主动语态中的主语放 by 之后作宾语，主格变宾格。 三、被动语态的句式结构 1. 一般现在时的被动语态的句式结构 基本句式 结构 例子 肯定句 主语+am/is/are+及物动词的过去分词（+其他）. The letters are sent on time. 这些信都按时寄出去了。 否定句 主语+am/is/are+not+及物动词的过去分词（+其他）.

How is tea produced? 茶是如何生产的？ 2. 一般过去时的被动语态的句式结构 基本句式 结构 例子 肯定句 主语+was/were+及物动词的过去分词（+其他）. These biscuits were bought by my mum last night. 这些饼干是我妈妈昨晚买的。 否定句 主语+was/were+not+及物动词的过去分词（+其他）.

Who may be invited to the party? 谁可能会被邀请参加聚会？ 拓展（1）含有情态动词的一般疑问句的答语，一般应保留原句中的情态动词；但如果问句中用 must 表示“必须”的含义时，否定回答常用 needn’t 或 don’t/doesn’t have to。如： —Must the report be finished today? ——报告必须今天完成吗？ —Yes, it must./No, it needn’t/doesn’t have to. ——是的，必须。/不，不必。 1. 在主动语态中，make, keep 等使役动词和 see, watch, hear, feel 等感 官动词后接省略 “to” 的动词不定式作宾语补足语。但在变为被动语态时，要加上 “to”。如： The sad movie made Amy cry. 那部悲伤的电影把艾米弄哭了。 →Amy was made to cry by the sad movie. 艾米被那部悲伤的电影弄哭了。 语法精练 一、单项填空 （ ）1.
