主句：It is possible +（that 从句）. It做形式主语从句1：that 从句，是整句的真实主语，其内部主干是we are doing sth。 逗号后的messages到最后是前面的messages的同位语。从句2：定语从句，同位语messages后面that引导的部分，用来修饰messages。其内部主干是 messages (即that) are done and done整个句子的意思是：有可能我们的任何举动在无意中都传递了某些信息，这些信息无意中被别人获得并用于组成他们的观点。

when, while和as的用法： （1）三者均可表示“当……的时候”，如果主句谓语动词表示的是短暂的动作，而从句表示的是一段时间，三者可以通用。例如： I met an old friend of mine as / when / while I was walking along the street. （当我沿街散步时，碰见了我的一个老朋友。） （2）as和when引导的时间状语从句中，谓语动词可以是终止性动词，while引导的时间状语从句中，谓语动词一般是延续性动词。例如： It was raining hard when we got to the airport. （当我们到达机场时，天正下着大雨。）（不能用while 引导） （3）as强调主句谓语动词与从句谓语动词表示的动作同时发生；while强调主句谓语动词表示的动作持续于while从句所指的整个时间内；when可以指主句谓语动词和从句谓语动词所表示的动作同时或先后发生。例如： She sang as she went along. （她边走边唱。） Please listen to me carefully while I read. （我朗读的时候，请仔细听。） When he reached home, he had a little rest. （回到家以后，他休息了一会儿。） before的用法与前面三个词区别较大,具体如下: 1. 表示“在…..之前就…..”。 Mary had finished her homework before her mother returned. 2. 表示“过了多久后才…….. ，动作进行到什么程度才……” The man almost knocked me down before he saw me . They walked about 30 miles to the west before they saw a village .

I would / will die before I surrender . 7. 表示“否则；以免” Do it now before you forget . I will write it down before I forget it . 8. 用于句型“it was +时间段+ before …” 表示 “过了多久才…” It was three days before he came back. . 9. 用于句型 “ it was not long +时间段+ before …” 意为“不久就….” It was not long before he sensed the danger of the position . 10. 用于句型“it will be(not )+时间段+ before….”表示“要过多久/ 不久…才…” It will be half a year before you graduate from this school .
