32、的主语是谓语动作的承受者时，主、谓之间 的关系称为被动语态。例如： He teaches us English. （主动语态）他教我们英语。 Our English is taught by him. （被动语态）我们的英语是由他教的。 He speaks English. （主动语态）他说英文。 English is spoken in many countries all over the world. （被动语态）世界许多国家都讲英语。 在被动语态的句子中，谓语部分的结构是be + 过去分词。 被动语态的句子有时态的变化，这个变化反映在be动词上。 也就是说，把一个句子做成被动语态的句子

33、，只需要写出be 动词的所需时态，再加上所给动词的过去分词就行了。当然， 这只是指谓语部分而言。我们知道，be动词作为一个独立的 谓语动词有自己现在分词（being）和过去分词 （been）。那 么，下面我们来看看be在各种时态中的变化形式： 被动语态的结构被动语态的结构 主动语态主动语态被动语态被动语态被动语态否定式被动语态否定式 一般现在时一般现在时I tellI am toldI am not told 一般过去时一般过去时I toldI was toldI was not told 一般将来时一般将来时I will tellI will be toldI wont be told 现在

34、进行时现在进行时Im tellingI am being toldI am not being told 现在完成时现在完成时I have toldI have been toldI havent been told 例如：例如： 1. English is spoken in New Zealand. 2. I wasnt invited, but Ive come anyway. 3. It is going to be made by him. 4. He will be told later on. 5.The building has been built for three yea

35、rs. 6.The dishes can be washed in half an hour. 7. My car is being repaired. English is spoken in many countries all over the world . （一般现在时）世界上许多国家都讲英文。 Some TV sets for sale in the department store were stolen last night. （一般过去时）那家商场用来出售的部分电视机昨晚被盗。 He wont be allowed to marry Larra by his father.

36、（一般将来时）他父亲不会让他娶拉拉为妻的。 They would be sent to the army when they finished the training. （过去将来时）他们结束训练时将被派往部队。 The project is being carried out. （现在进行时）这个计划正在执行中。 The case was being investigated then. （过去进行时）那时这案子正在调查中。 This novel has been translated into several languages. （现在完成时）这本小说已被译成了几种语言。 They s

37、aid that production costs had been reduced. （过去完成时）他们说生产成本已经下降了。 一般来说，在我们日常生活中，能用主动语态的时候就尽量 不去用被动语态。只有在下列情况中我们才用被动语态： (1) 不清楚动作的执行者是谁, 例如: The front window in the classroom was broken yesterday. 昨天，教室的前窗被打破了。 (2) 说话人对宾语的兴趣大于对主语的兴趣（这时可用by引导 出动作的执行者），例如： My TV set is being repaired in the shop. 我的电视机正

38、在这店里修。 (3) 出于修辞的原因，或是说为了更好地安排句子。 几种特殊的被动结构几种特殊的被动结构 (1) 关于带情态动词的被动结构 带情态动词的被动结构的固定句式为“情态动词 + be + 过去分词”。例如： The debt must be paid off before next month. 那笔债务必须在下个月前付清。 Oil can be turned into energy by burning it. 油经过燃烧可变为能源。 (2) 关于带有两个宾语的主动态变成被动态 我们先来看看“带有两个宾语的主动态句子的结构”，重 点看谓语部分 ： She sent me a nove

39、l on my birthday . 主 谓 间接宾语 直接宾语 状语 I allowed him an hour to finish the work . 主 谓 间接宾语 直接宾语 状语 She sent me a novel on my birthday. (主动) I was sent a novel on my birthday. (被动) A novel was sent to me on my birthday. (被动) My brother bought me a watch yesterday. (主动) I was bought a watch yesterday. (被

40、动) A watch was bought for me by my brother yesterday.(被动) 几种特殊的被动结构几种特殊的被动结构 (3) 关于带有复合宾语的主动态变成被动态 如果将带有复合宾语（既：宾语 + 宾语补足语）的主动 态的句子变成被动态的句子，我们只能选择原来句子的宾语 作被动态句子的主语例如： The story made us laugh . We were made to laugh by the story. They asked me to help them. I was asked to help them. We saw them coming

41、 over. They were seen coming over. 几种特殊的被动结构几种特殊的被动结构 巩固练习巩固练习 ( ) 1The Peoples Republic of China _ on October 1, 1949.
