gonna是going to的缩写。
going to是将要去；准备去的意思。短语搭配be going to就要；快要；将要。
be going to 的含义：表示按计划或安排要发生的动作，也可以表示推测将要或肯定会发生的动作，有“准备;打算”的意思。be going to 后面需要接动词原形。句子中时常有表示将来的时间状语。
例如:1、The board of directors are going to hold a meeting this Friday.周五董事会准备召开会议。
2、It is thundering outside. It's going to rain.看那些乌云，快要下雨了。
be going to 结构中的助动词be很少用原形。立足于现在的时间表示 将来的打算，be动词有三种形式：am，is，are。主语是I，be动词用am，主语是第三人称单数，be动词用is，主语是复数时，be动词用are。
