要改为被动语态,还没学.但题目里有,做不出!

我来帮你
题：The workers will build the highrise next year.(改为被动语态)
问：The highrise will be built next year.
顺便告诉你:
主动语态改被动语态的方法
1）将主动语态改为被动语态应注意以下三个方面：①将主动语态的宾语改为被动语态的主语；②将主动语态的谓语动词改为“be＋过去分词”结构；③将主动语态的主语改为介词by之后的宾语,放在谓语动词之后（有时可省略）.
2）含直接宾语和间接宾语的主动语态改为被动语态时有两种情况：①把间接宾语改为被动语态的主语,直接宾语仍保留原位；②把直接宾语改为主动语态的主语,此时,间接宾语前要加介词to或 for.如：He gave the boy an apple．→The boy was given an apple．（或An apple was given to the boy．） Her father bought her a present．→She was bought a present by her father．（或A present was bought for her by her father．）
3）不带to的动词不定式作宾语补足语的主动语态,改为被动语态时不定式前要加to.如：They watched the children sing that morning．→The children were watched to sing that morning．
4）带复合宾语的动词在改为被动语态时,一般把主动语态的宾语改为主语,宾语补足语在被动语态中作主语补足语.如：We call him Xiao Wang．→He is called Xiao Wang． He cut his hair short．→His hair was cut short． They told him to help me．→He was told to help me．
5）短语动词是不可分割的整体,改为被动语态时要保持其完整性,介词或副词不可遗漏.如：We must take good care of the young trees．→The young trees must be taken good care of．
6）含有宾语从句的主动结构变为被动结构时,通常用it作为被动结构的先行主语,从句放在句子后面；也可采用另一种形式.可以这样转换为被动结构的动词有know,say,believe,find,think,report等.如：People believe that he is ill．→It is believed that he is ill．（或：He is believed to be ill．）
