(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： 一般过去时： 一般将来时： 过去将来时： 现在进行时： 过去进行时： 现在完成时： 过去完成时： 注被动语态没有将来进行时和过去将来进行时。,am / is / are + done was / were + done shall / will + be done should / would + be done am / is / are + being + done was / were + being + done have / has + been + done had + been + done,(三) 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 was broken after class. ” 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. The cup was broken by Paul. 3.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.,(四)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 special class to help poor readers.

A new computer has been bought. (正确) A new computer have been bought. (错误) 2. 含有双宾语的主动句变被动句时，可分别将其中的一个宾语变为主语，另一个不动，一般变间接宾语为主语时比较多。 My uncle gave me a present on my birthday. I was given a present on my birthday. 如果把直接宾语(指物)改为主语，则在间接宾语(指人)前加适当的介词，如上句还可以说：A present was given to me yesterday.,保留宾语,×,1.They make shoes in that factory. 主语+及物动词+宾语,Shoes are made (by them) in that factory. 一般现在时： S(主语）+am/is /are +过去分词,变为被动语态,2.
