To Carrefour supermarket, I saw a high shelf full of a variety of goods, dazzling. To the daily necessities area, I saw toilet paper neatly placed on the shelf, there are many brands of Qingfeng, Shujie and Weida.

到了家樂福超市，我看到高高的貨架上擺滿了各種各樣的商品，琳瑯滿目。到了日用品區(qū)，我看到了衛(wèi)生紙整齊地擺在貨架上，有清風、舒潔、維達很多品牌。

I took Vader with me. There are ten rolls in a whole package. The price is 27 yuan. My mother reminded me, "Qingfeng is promoting sales. It's a pack of twelve rolls, and it's only 25. It's a good deal." So I replaced Vader with breeze and put it carefully into the cart.

我隨手拿了維達，一整包有十卷，價格是二十七元。媽媽提醒我說，“清風在搞促銷，十二卷一包，只賣二十五，很合算。”于是我又把維達換成了清風，小心翼翼地放進推車里。

Leaving the tissue area, we went shopping for garbage bags. I took a roll of garbage bag to my mother, but my mother shook her head and said, "our garbage can is 60 * 50cm, this is 60 * 40cm, it can't be put on. So I helped my mother find a roll of 60 * 50cm, the price was seven yuan. We also selected toothpaste, toothbrush, towel and so on to put into the shopping cart.

離開紙巾區(qū)，我們?nèi)ミx購垃圾袋。我拿了一卷垃圾袋給媽媽，可是媽媽搖搖頭說：“我們家的垃圾桶時60*50cm的，這是60*40cm的，肯定套不上去。于是我又幫媽媽找了一卷60*50cm的，價格是七元。我們還挑選了牙膏、牙刷、毛巾等放進購物車。

Pick out the daily necessities and we'll come to the cashier. "The total is 80 yuan," said the cashier's aunt We paid the money and went home happily. Walking on the road, I thought: "the original shopping to compare three, to buy the most cost-effective."

挑好日用品，我們來到收銀臺。收銀員阿姨說：“共計八十元?！蔽覀兏逗昧隋X，就高高興興地回家了。走在路上，我想：“原來買東西要貨比三家，要買性價比最高的。”
