Step 3

The Present Perfect Passive Voice

现在完成时的被动语态的用法

过

1.表示一个被动的动作发生在说话之前,强调对现在造成的影响和结果.

The door has been locked.

2.表示一个被动的动作或状态开始于过去,持续到现在,并可能持续下去,常与for 或

since引导的时间状语连用,或用于How long...?句型中. 程

The important problem has been discussed for nearly two weeks.

How long has the machine been used?

时间状语：

以现在为参照的时间状语：just, already, ever, yet, before, once, never 包括现在时间在内的时间状语：now, today, this morning, this month, this year 表示一段时间的状语: so far, (ever) since, (for) a few hours, for a long time, long, for/ in句型

He has been sent to study the new technology in the company. 否定句:在have /has 后加not He has not been sent to study the new technology in the company. 一般疑问句: have /has 提前

Has he been sent to study the new technology in the company? 特殊疑问句: 疑问词+have (has)+主语+beenV过去分词.+...? Where has he been sent to study the new technology? How many shopping centers have been built in this city?

Something worth attention: 1.现在完成时的被动语态的两个助动词,即have/has和been,两者缺一不可。

2. 同一般过去时的被动语态的区别。一般过去时的被动语态所表示的动作或状态与现在的情况没有联系,而现在完成时的被动语态则强调与现在情况的联系. 3.一些特殊动词,如borrow, finish, begin, buy, start, return, marry, open, join等构成的现在完成时的被动语态不能与表示一段时间的状语连用。若要表达相应的意思,则需改换动词或时态
