(this kind of TV set 是 make 这个动作的承受者，所以要用被动语态 be made ).要指出动作的执行者，可用“介词by+动作的执行者”结构。例：This letter was written by my mother.2.其他句式变化：否定句：This kind of TV set is not made in that company.一般疑问句：Is this kind of TV set made in that company?特殊疑问句：Where is this kind of TV set made ?1. 什么情况下用被动语态：1）不清楚动作执行者是谁时：例如：His bike has been stolen.(不知道也没有办法知道是谁干的)2）没有必要或不想说出动作执行者时：例如：Rice is grown well there.3) 强调动作的承受者时：例如：This book has been sold out, but that one hasnt.4及物动词能构成被动语态，不及物动词不能构成被动语态。只有这些不及物动词与介词或副词构成不可分割的短语，并且带有宾语时，才可用被动语态。例如：The old man is looked after well in the hospital.5 有些动词带有双宾语，变成被动语态时，两个宾语都可以作被动语态中的主语，但间接宾语作主语的较多。例如：He gives me one yuan a day.I am given one yuan a day./ One yuan is given to me a day.6 有些动词后接不定式作宾语原可省“to”的，变成被动语态时要加上“to”.例如：The teacher often makes us read English aloud in the morning.We are often made to read English aloud in the morning(by the teacher).Step3. 用括号内所给动词的被动语态填空。1.
