There are a couple of reasons booming this problem.
There are a couple of reasons booming this problem. 此处怎么看待booming?是属于前半部分作为形容词”大受欢迎的” 还是属于后半部分 There are a couple of reasons 〔booming this problem〕? boom动词除了繁荣的意思还有什么呢?
属于后半部分,boom this problem 原句是There are a couple of reasons which are booming this problem. 定语从句,此处相当于是省略了which are boom [ bu:m ] .. n.繁荣,隆隆声 v.急速发展 这相当于是使问题更复杂更繁复等
