接宾语变为主语，而指“物”的直接宾语则不变。e.g.HegavemesomeadviceonlearningEnglish.IwasgivensomeadviceonlearningEnglish(byhim).(2)如果要把指“物”的直接宾语变为主语，则在间接宾语前加to或for。

e.g.Mymotherbroughtmeabike.Abikewasbroughttome(bymymother).一般过去时的被动语态3．含双宾语和复合宾语的主动句变为被动句的方法(3)含有复合宾语的主动句变为被动句时，要将其中的宾语变成

主语，宾语补足语不变。e.g.JimaskedTomtofinishtheworkatonce.Tomwasasked(byJim)tofinishtheworkatonce.(4)如果宾语补足语是不带to的动词不定式，主动语态变成被动语态

时要加上不定式符号to。

e.g.WeoftensawJohnplaybasketballintheplayground.

Johnwasoftenseentoplaybasketballintheplayground(byus).一般过去时的被动语态e.g.Mygrandmatookgoodcareofmydog.→Mydogwastakengoodcareofbymygrandma.奶奶把我的狗照顾得很好。(其中介词of不能漏掉)含有动词短语的主动语态变为被动语态时，不可丢掉构成动词短语的介词或副词。注意Paper______first______about2,000yearsagoinChina.A．is;creating B．is;createdC．has;created D．was;created 可用语法判断法解答本题。句意：在中国，纸大约在两千年前首先被创造了出来。句中的ago是一般过去时的标志，且纸和创造之间是被动关系。因此本题考查的是一般过去时的被动语态，其结构是：was/were+及物动词的过去分词。因此，正确答案是D。D
