特殊疑问句 特殊疑问词+was / were+主语+及物动词的过去分词 (+by短语)+其他？ Who was sent to our school to give the report 谁被派到我们学校做报告？
3.使用被动语态的注意事项
要点 举例
含有双宾语的主动结构变被动结构时，不要忽略间接宾语前的介词，既可将间接宾语转化为主语，也可将直接宾语转化为主语。若将间接宾语转化为主语，则保留直接宾语；若将直接宾语转化为主语，则保留间接宾语，且在被保留的间接宾语前加上介词to或for We gave some flowers to Miss Gao on Teachers' Day. →Some flowers were given to Miss Gao on Teachers' Day. 教师节那天，我们给高老师送了一些花。
My mother gave me a pencil.→I was given a pencil by my mother.（间接宾语转化为主语）→A pencil was given to me by my mother.（直接宾语转化为主语）妈妈送给我一支铅笔。
续表
要点 举例
含有动词短语的主动结构变被动结构时，不要漏掉短语中的介词或副词 We handed in our homework last Friday. →Our homework was handed in last Friday.上周五我们上交了家庭作业。
在含有使役动词(make, let等)或感官动词(see, watch, notice, hear等)的主动语态的句子中，这些词后常跟省略to的动词不定式，但改为被动语态时要把省去的to还原 I saw him cross the road and enter the shop. →He was seen to cross the road and enter the shop. 我看到他穿过马路进入了商店。
4. 主动形式表示被动意义的情况
（1）feel, taste, sound, smell, look, keep, remain, stay, seem等说明主语的状态、性质、特征的系动词，常常以主动形式表示被动含义。如：
The cake tastes good. 这个蛋糕尝起来很美味。
（2）wash, write, wear, sell, read, clean, open 等动词作谓语时，常常可用主动形式表示被动含义。这类动词往往与easily, well, badly, smoothly等副词连用，表示主语的属性特征。如:
This kind of cloth washes easily. 这种布很好洗。
（3）take place, happen等不及物动词或动词短语，可用主动形式表示被动含义。如:
Great changes have taken place in our school in the last 5years. 在过去的5年里，我们学校发生了巨大的变化。
（4）need, require 等表示“需要”意义的动词，后接动词的-ing形式，往往表示被动含义。need / require doing=need / require to be done 意为“需要被做”。如:
The bike is broken and it needs / requires repairing. =The bike is broken and it needs / requires to be repaired. 自行车坏了，需要修理。
（5）be worth doing sth. 意为“值得做某事”，也可以表示被动含义。如:
The book written by Mo Yan is worth reading. 莫言写的这本书值得一看。
