They'll be put up on the school website.
Will computers be used more than books in the future
Will books be replaced by the Internet
一般将来时的被动语态： will + be +过去分词
一般现在时—— am／is ／ are +动词的过去分词
一般过去时—— was／were +动词的过去分词
被动语态的构成：be +动词的过去分词
被动语态：主语是动作的承受者 。
当我们不知道谁是动作的执行者，或者没有必要指出谁是动作的执行者时，或者只需强调动作的承受者时，要用被动语态。

主动语态如何改成被动语态？

2. 主动语态的谓语动词改成被动语态的be动词加谓语动词的过去分词形式。
do
3. 注意保持时态和人称的一致。
4. 带双宾语的谓语动词有两种改法。当把直接宾语改成主语时，谓语动词后必须加适当的介词: to，for。
