be caught up with这个词组的意思是被赶上，这是典型的被动语态。英语的动词有两种语态：主动语态和被动语态。主动语态表示主语为谓语动词的执行者，被动语态表示主语为谓语动词的承受者。被动语态的基本形式由助动词be加上及物动词的过去分词构成。The station was bombed by the tourists.车站被恐怖分子炸掉了。The road will be widened.道路即将扩宽。The baby is taken care of by his granny.宝宝由奶奶照看。Privileges must be done away with.特权必须废除。The matter will be dealt with as soon as possible.这个问题会尽快处理。
