星期天,我和姑姑一起去买菜,姑姑说,想吃什么买什么,但要我来算账。心想:这点问题难不倒我,于是,我就爽快地答应。我比较喜欢吃西红柿,一看西红柿2.8元一斤我买了2斤,我在脑子里想2.8+2.8=4.6元,然后我又买了些黄瓜,黄瓜2.2元一斤我买了2斤,该是多少元呢?答案迅速被我想到:2.2+2.2=4.4元,我又想4.6+4.4=9元。天哪,我太会省钱了,还不足10元呢。可是,似乎少了点调料,于是,我又买了点葱,0.6元一斤我买了3斤,我自言自语地说0.6+0.6+0.6=1.8元,9+1.8=10.8元。 On Sunday, I went to buy food with my aunt, my aunt said, what to buy, what to buy, but to me. I thought: This problem is hard to beat me, so I readily agreed. I prefer to eat tomatoes, a look at tomatoes 2.8 yuan a catty I bought 2 pounds, I think 2.8 +2.8 = 4.6 yuan in my mind, and then I bought some cucumber, cucumber 2.2 yuan a catty I bought 2 pounds, How much is this? The answer quickly I was thinking: 2.2 +2.2 = 4.4 yuan, I would like 4.6 +4.4 = 9 yuan. God, I will save too much, less than 10 yuan. However, it seems a little less seasoning, so I bought some onions, 0.6 yuan a pound I bought 3 pounds, I say 0.6 + 0.6 + 0.6 = 1.8 yuan, 9 + 1.8 = 10.8 yuan.
