英语句子
The meeting will be put off in case it rain
请问为什么有两个动词be put 不是一句子只可以一个动词吗个

put off 推迟延迟；
put 的过去式也是put . 是其原形.
上例中 Be+过去式是英语的被动式
但是be+过去分词”并不一定都是被动语态,有时是系表结构.
一般来说,当“be+过去分词”表示动作时为被动语态,be是助动词,be后面的过去分词是主要动词,动作的对象是主语;例句：The glass was broken by the boy（被动语态）.玻璃杯被那个男孩打碎了.
当“be+过去分词”表示主语所处的状态时为系表结构,be是连系动词,be后面的过去分词是表语,相当于形容词.例如:The glass is broken.玻璃杯碎了.(系表结构)
除上述讲到的从意义上加以区分之外,还可以从时态上进行区别:
:被动语态除用于一般时态和完成时态外,还可以用于其他各种时态,而系表结构中的系动词be只有一般时态和完成时态.例如:The m achine is being repaired.机器正在修.(被动语态)A new school will be built here.这里将要建一所新学校.(被动语态)The door is locked.门锁着.(系表结构)The door has already been locked.门已经被锁上.
