I went to the supermarket the other day with 10 yuan. I was a bit hungry, so I decided to buy a small pack of cookies which cost me 4 yuan. After I ate them, I was still hungry, so I decided to buy a small bag of potato chips which cost me another 3 yuan. After I ate them both, I was no longer hungry. However, I was very thirsty and wanted to buy a large bottle of milk to drink, but I didn’t have enough money left because even a small box of milk would cost me 2 yuan and I needed 2 yuan to pay the bus fare. So I gave it up at last.

　　几天前我带着10元去超市，我有点饿，所以决定花4元买一小包饼干。之后，吃完之后我仍然觉得饿，所以我又花了3元买了一小包薯片，吃完之后，我没再感到饿了。然而，我感到口很渴，想买一大瓶牛奶，但剩下的钱不够，因为即使一小盒牛奶都要2元，我还要2元支付车费，所以最后我决定不喝了。
