Task 2:thinking 1.

表示被动的动作发生在说话之前（即现在的过去），强调对现在造成的影响和结果。当动词为短暂动词时，可与already或yet连用，但不可与for或since引导的时间状语连用

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。

Task 3: summing up

Task 4: Notice 1.

现在完成时态有两个助动词

即have/has 和been, 两者缺一不可。

2.

注意与一般过去时被动语态的区别。

一般过去时的被动语态表示一个被动的动作发生在过去某个时候，其结果对现在没有影响。现在完成时的被动语态的动作或状态尽管发生在过去，但侧重说明该动作或状态对现在造成的影响和结果。

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。

4.

但许多不及物动词加介词或副词构成的动词短语，相当于及物

动词，也可以有被动语态。但动词短语是一个不可分割的整体，变为被动语态时,不可丢掉构成短语的介词或副词。
