被动语态是我们从初二就开始接触的，说起来其实很简单，概念也不多，但是它的难点就在于能否被判断出来，能否使用正确的时态。今天，就让知悦带大家揭开被动语态的神秘面纱。
被动语态的各种时态(其中done指过去分词)
一般现在时：am/is/are +done
一般过去时：was/were+done
一般将来时：shall/will+be done
一般过去将来时：should/would+done
现在进行时：am/is/are+being done
过去进行时：was/were+being done
现在完成时：has/have+been done
过去完成时：had+been done
将来完成时：shall/will+have been done

注意：1.不及物动词及不及物的动词短语不能用于被动语态。
2.某些感官动词或系动词可加形容词表示被动意义，如：look，taste，smell，feel等。
3.表示事物内在品质或性能的动词，用主动形式表示被动意义。
4.动词不定式的被动形式由to be+过去分词构成，表示动词不定式与其逻辑主语之间是被动关系。
