yesterday.主语谓语宾语Theofficewascleanedyesterday.主语+be+过去分词构成：一般过去时的被动语态由“主语+was/were+及物动词的过去分词”构成。助动词be有人称、数和时态的变化，其变化规则与be作为连系动词时完全一样。Presentation现以动词ask为例，将一般现在时和一般过去时被动语态的肯定式、否定式及疑问式列表如下：

肯定式否定式疑问式

一般过去时Iwasasked…He/She/wasasked…We/You/Theywereasked…Iwasnotasked…He/Shewasnotasked…We/You/Theywerenot

asked…WasIasked…?Washe/sheasked…?Werewe/you/theyasked…?

被动语态的构成被动语态由"助动词be+及物动词的过去分词"构成。人称、数和时态的变化是通过be的变化表现出来的。
