A Big Cost

I was shopping in the supermarket at this time yesterday. In fact, I didn't even make a shopping list, but after I set my first foot in the supermarket, I was attrcted by all of what I saw. In no more than 20 minutes, my shopping cart was filled-up with many colourful things. I was too happy to hide my excitement! I "drove" my "shopping cart" to check out with my VISA,. After （When？） I heard the voice of the cashier, I was shocked! It's so What a big (heavy) a expenditure expense! :-(
昨晚的这个时候我在超市买东西，其实我连一个消费清单都没有列出来，但是我的第一只脚踏入超市以后，就被我所看到的东西吸引了，不到二十分钟，我的购物车就被花花绿绿的东西装满了，我非常高兴难以隐藏我的兴奋，开着我的“购物汽”车去刷信用卡结账了，当我听到收音员的声音后，我被震惊了，这是一笔很大的消费啊！
