(主动) A new bridge will be built over the river. (被动) 汉语中常用“被”、“给”、“由”、“受”等词用来表示被动，而英语用：助动词be + 及物动词的过去分词构成。,(二) 被动语

5、态的时态、人称和数的变化 主要体现在be的变化上，其形式与系动词be的变化形式完全一样。以give 为例，列表如下： 一般现在时：am / is / are + given 一般过去时：was / were +given 现在进行时：am / is / are + being + given 过去进行时：was / were + being + given 现在完成时：have / has + been + given 过去完成时：had + been + given 一般将来时：shall / will +be+ given 过去将来时： should / would +be+ given

13、after class.,A great many letters can be written with the computer by him.,(四) 被 动 语 态 的 使 用 1.当不知道或没有必要指出动作的执行者时，常用被动语态，这时往往不用by 短语。 “Mr. White, the cup with mixture was broken after class. ”(只是告诉老师杯子坏了，不知是谁弄坏的，或不想说出谁弄坏的)。 2.突出或强调动作的承受者，如果需要说出动作的执行者，用by 短语。 These records were made by John Denver. 3

14、.当汉语句子的主语既不是动作的执行者，也不是动作的承受者时，这时常用in + 名词作状语，而代替 by 短语。 These cars were made in China. 15, 000 cars will be produced each year in the new factory.,(五)主动语态变被动语态的方法,（1） My aunt invited me to her dinner party. 主语 谓语 宾语 I was invited (by my aunt ) to her dinner party. 主语 谓语 宾语 （2） The school set up a sp

19、e Great Wall is known to people all over the world. (不用by短语),3. 由动词+ 介词或副词构成的短语动词，要把它们作为整体看，即把它们看成一个及物动词，介词或副词不可拆开或漏掉。这类动词有： 不及物动词+ 介词，如: agree to, ask for, laugh at, operated on, listen to, look after, think of, talk about 等。 The patient is being operated on.

21、而宾语补足语保留在谓语动词后面。如： We always keep the classroom clean. The classroom is always kept clean. She told us to follow her instructions. We were told to follow her instructions. 注意：在see, watch, hear, notice, listen to, look at, make, feel等动词后作宾语补足语的动词不定式都不带 to，但改成被动语态后都带to，这时不定式为主语补足语，也就是说不定式作主语补足语不存在省略to

22、 的问题。,We often hear him play the guitar. He is often heard to play the guitar. 注意：带有复合宾语的句子，如果宾语补足语是名词， 变被动句时，应将宾语变为主语，不要误把宾语补足语 的名词作主语。如： Tomatoes were first taken back to Europe and people called them love apples. 误：Love apples were called them. 正：They were called love apples.,5. 还有一种短语动词由动词+ 名词+

23、介词构成，变被动语态有两种形式，如下： 1) We take good care of the books. The books are taken good care of. Good care is taken of the book. 2) You must pay attention to your pronunciation.
