有个文本文档 1.txt，里面的内容类似如下：

Alibaba Group saw its gross merchandize volume breaking last year's record within half a day after the 24-hour online shopping festival kicked off on Nov 11.

The e-commerce giant announced earlier Wednesday its unaudited figure, saying the gross merchandize volume on its Tmall platform reached 57.1 billion yuan ($8.98 billion) at 11:50 am and about 71.61 percent out of the volume generated from mobile channels, such as smartphones and tablets.

现在想把这个txt的内容全部转换成大写！！！
