Grammar
一、构成 学习一般将来时的被动语态，首先应掌握其各种结构形式。 1．肯定式will（shall）＋be＋动词的过去分词
2．否定式will（shall）＋not＋be＋动词的过去分词
3．疑问式Will（Shall）＋主语＋be＋动词的过去分词？
简略回答Yes，主语＋will（shall）．No，主语＋won't（shan't）． 现在，请看实例：
A） 肯定句：Anew stadium will be put up here．
否定句：Anewstadium will not（won't）be put up here．
疑问句及简略回答：Will a new stadium be put up here？Yes，it will．／No，it won't． 特殊疑问句及回答：What will be put up here？A new stadium．
B）A lot of athletes will be invited to Beijing．But those who have used illegal drugs will not be invited．（但那些使用违禁药物的将不被邀请。）Will some world-famous singers be invited？Yes，they will．Who else will be invited？Some judges and sports officials，of course． 二、其他结构
表示将来意义的被动结构还有： 1．be going to be done； 2．be to be done；
3．will（shall）＋get ＋done等。
例如： Some old buildings are going to be put down． The 29th Olympic Games is to be held in Beijing in 2008． The workers will get paid before the end of December． 同学们也要注意这些结构的否定式、疑问式等。例如：
These trees are not going to be cut down．Are these trees going to be cut down？Yes，they are． The machines are not to be repaired tonight．Are they to be repaired tomorrow？Yes，they are． 三、注意事项
使用一般将来时的被动语态时，应注意以下两点：
1．在时间、条件状语从句中，应使用现在时表示将来时。同样，应使用现在时的被动语态表示将来时的被动语态。例如：He says he will leave the company if he is punished for this． 2．使用一般将来时被动语态时，学生易遗漏被动式中的be。
