Answer 1

【答案】

【1】 This library was built by us last year.

【2】 TV was watched by me yesterday evening.

【3】 I was passed a book. /A book was passed to me by him.

【4】 I was heard to sing by her in the next room.

【解析】

本题是被动语态专题。需注意人称的变化，主动句的宾语在被动句中做主语，是动词的受动者，需用“be done”结构；原句主语在被动句中需用“by sb.”结构。be动词需根据主语人称和时间状语做相应变化。本题句子都是一般过去时态，所以转换后都是一般过去时的被动语态，同时不要忘记大写句子的首字母。

【1】原句宾语this library在被动句中是动词built（建造，build的过去式）的受动者，单数形式，系词需用was。根据句意结构，可知填This library was built by us last year。

【2】原句宾语TV在被动句中是动词watched（看，watch的过去式）的受动者，单数形式，系词需用was。根据句意结构，可知填TV was watched by me yesterday evening.。

【3】原句宾语a book在被动句中是动词passed（传递，pass的过去式）的受动者，单数形式，系词需用was。pass sth. to sb.（把某物传给某人）；根据句意结构，可知填I was passed a book. 或A book was passed to me by him.。

【4】原句宾语me在被动句中是动词heard（听，hear的过去式）的受动者，单数形式，系词需用was。hear sb. do sth.（听到某人做某事），是省略to的不定式，在被动语态中需恢复不定式符号；根据句意结构，可知填I was heard to sing by her in the next room.。
