主动语态变被动语态的步骤（宾主换，谓被动） 1、主动语态的宾语变为被动语态的主语； 2、主动句的谓语动词变为被动结构； 3、主动句的主语变为被动句的宾语，由by 引出， 当不强调动作的执行者时，常省略。 Eg: Months ago we sailed 10000 miles across the open sea, which ____(call) the Pacific ,and we met no storms. * 3.含有复合宾语的主句变为被动句时，将其中的宾语变成主语，宾语补足语不变。 We saw him sitting there without doing anything (主动语态) --He was seen sitting there without doing anthing (被动语态) 如果宾语补足语是不带to的动词不定式，变成被动语态要加上to （和注意问题的第一个一样） I saw my teacher enter the reading room just now.(主动语态) --My teacher was seen to enter the reading room just now(被动语态) * 4.特殊疑问句的被动语态 和主动句一样，仍将疑问词置于句首。若主句的疑问词是who,变成被动句式要变为by whom置于句首；主动句的疑问词是whom时则改为who,其余疑问句不变。 Who bought the book? --Who was the book bought by? --By whom was the book bought? Whom did you ask?—who was asked by you? What can we do? --what can be done by us? * * * get / have sth. done 含被动 (找人做某事) 十六岁的孩子不应该打耳洞。 Sixteen-year-olds should not be allowed to get their ears pierced. I should get my shoes repaired. He should have his hair cut. Let’s get the work done. * 口诀1：宾提前变主，主变介by宾，被动be加done,时态看主动。 口诀2：如 遇双宾语，最好变间宾，如若变直宾 语后加to/for(pass,lend,buy,write,bring,show,tell…) 口诀3：有些动词真奇怪，主动句中to 离开，被动句中to回 来。两听，两感觉，三做，四看 He made me do the work. I was made to do the work by him. 口诀4.含动词词组的被动语态，须将其看作一个整体，不可把它们分隔开来。 They take good care of the baby. The baby is taken good care of by them * * 各种时态的被动结构练习 1、The Chinese food _____ to be the healthiest in the world.
