为什么我不去的理由是xxx，

那是说这道题省略了why，其实不省略也可以算对，是这样吗？谢谢指教：）

大全注释

朗文

reason: "the reason...was because...”is bad english. It is better to say the reason...was that..." and gives an example" the reason he was driving so fast was that he was late for an important meeting." After "the reason" there is without "why"
