英语八年级下册第八单元知识3
一般将来时被动语态
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：
肯定句：A new stadium will be put up here.
否定句：A new stadium 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.
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。例如：
【误】A new film will shown at the cinema next week.
【正】A new film will be shown at the cinema next week.
【误】Is this bridge going to completed before the end of this year?
【正】Is this bridge going to be completed before the end of this year?
四、基本结构
shall/will + be + done
