专题09 必修二 Unit 3 现在完成时被动
一、定义
现在完成时的被动语态强调一个发生在过去的被动性动作持续到现在或对现在造成的影响或结果。
二、构成与形式
1. 现在完成时被动的基本构成：have / has + been +及物动词的过去分词
2. 现在完成时的被动语态的形式
1)肯定式：主语+have / has + been +及物动词的过去分词+其他。
例：The problem has already been solved.
2)否定式：主语+have / has + not + been +及物动词的过去分词+其他。
例：They haven't been told the exciting news yet.
3)一般疑问式：Have / Has+主语+been+及物动词的过去分词+其他
例：Has his new novel been translated into English yet
4)特殊疑问式:特殊疑问词(组)+have / has+主语+been+及物动词的过去分词+其他
例：How long has the car been used
三、用法
1. 表示过去发生的动作对现在造成的影响与结果。当动词为短暂性动词时,可与already, yet, just, never, recently, before等副词连用。
例：I'm sorry, but the letters haven't been typed yet.
很抱歉,这些信件还没有被打印出来。(结果是现在还拿不到这些信件)
2. 表示一个被动的动作或状态开始于过去, 持续到现在, 并有可能持续下去。常与for或since引导的时间状语连用, 或用于“How long... ”句型中。
例：The plan has been discussed for nearly 2 hours.
这项计划已被讨论了近两个小时了。
四、注意事项
1. 现在完成时的被动语态有两个助动词, 即have / has和been, 两者缺一不可。
2. 现在完成时的被动语态与一般过去时的被动语态的区别:
1)一般过去时的被动语态：侧重于表示一个被动的动作尽管发生在过去,但其结果对现在没有影响。
2)现在完成时的被动语态：表示一个被动的动作发生在过去某个时候, 该动作对现在造成了影响(或产生了结果)。
例：The big fire was put out two hours ago. vs. The big fire has been put out. (强调现在火灭了)
3. 非延续性动词在现在完成时的被动语态中的运用。
非延续性动词,如borrow, finish, begin, start, buy, marry, open, join等构成的现在完成时的被动语态不能与fo或since引导的表示一段时间的状语连用, 但可与already或yet连用。
这类动词的否定式可表示动作的持续过程, 具有持续性, 因而可与since或for构成的时间状语连用。
例：No books have been bought since last week. 自上周以来, 没有人来买过书。
4. 动词短语是一个不可分割的整体,在被动结构中要保持其完整性,不可省略动词短语中的介词或副词。
例：It is said that the problem has been looked into. 据说已经调查了这个问题。
