to be built是什么结构
问题描述:
to be built是什么结构
The radio says a wild animal zoo (is to be built )in our city.此句中的括号部分是什么结构?从没见过这种形式的被动语态呀
能够再举一些例子加以详细说明吗
答
广播里说本市将要建一座野生动物园.
is to ...是be to + V.结构,表示将要去做什么事.
因为动物园是将要被建起来的,是被动,所以后面动词V.部分加的是 be built.
[补充]
be to + V. 中的be to用作情态习语,表示将会、计划、安排、应该、可能等等含义.可以看以下一些例句:
He is to have a holiday. 他将去度假.(将会)
The committee is to meet today. 委员会成员安排今天碰头.(计划、安排)
You are to go to the hotel where rooms have already been booked for you. 你们应该去那家已经订好房间的旅馆.(应该)
再比如:
The municipal authority is to build a wild animal zoo in our city. 市政当局计划在本市建一座野生动物园.(计划、安排)
变被动语态,就是:A wild animal zoo is to be built in our city.
再作为间接引语,就是:The radio says ... 广播说...云云.
