16.If you are referring to my winning the English speech contest，I don't think it's such a big deal.

四级词汇讲解:

refer to含义丰富，可意为“参考;涉及;适用于;指的是”。在这句话里,其意为“指的是”，相当于mean。 a big deal是口语表达，含义为“意义重大的事情”。如：

1 ) That's a big deal.那是件大事。
2 ) I just want to eat it now; what's the big deal?我就想现在吃，有什么大不了的?
3 ) I dan't hide it, but I don't make a big deal about it.我并没有遮掩，但我也没有大肆渲染。
本题的解题关键就在于对big deail的理解。
