到今天我才发现原来数学一直藏在我们的生活中，只要仔细观察你一定会发现很有趣知识。 数学老师布置了一个很奇怪的作业，让同学们亲自到菜场走一走。
我一跑回家就气喘吁吁地对妈妈说：“妈妈…今天你休息！我到菜场买菜！”妈妈开心地说：“什么时候我家的小公子也会帮妈妈干活了？”。当然她还是放心地让我一个人去。 来到菜场，不知道怎么的，我就开始心慌了。毕竟这是我第一次自己来菜场买菜，总是担心挑不好菜。
不过一会儿我就平了心中的不安，我是个男子汉怎么能被小小的菜吓到呢？为了能买到最实惠的最新鲜的蔬菜我问了好几家菜摊。终于，我在一个菜摊前停了下来，只见菜摊上的青菜还带着小水珠，看样子是刚刚从菜地上摘的。摊主是一位长相和蔼的老伯伯。我问了青菜的价格，经过一番讨价还价，我把价格从七角一斤压到六角一斤，我挑选了几株小一点的，嫩一点的青菜放到袋子中。
But after a while, I was calm. How can I be frightened by a small dish when I am a man? In order to buy the most affordable and fresh vegetables, I asked several vegetable stalls. Finally, I stopped in front of a vegetable stall. I saw that the vegetables on the stall were still carrying small water drops. It seemed that they had just been picked from the vegetable field. The stall owner is a kind-hearted old uncle. I asked about the price of green vegetables. After some bargaining, I pressed the price from 7kg to 6kg. I selected a few smaller and tender green vegetables and put them in the bag.
心想：还真不错！小贩一称有两斤，我心中很快出现了：0。6×2=1。2元，立即付钱就离开了。心中还暗自高兴：这下子妈妈一定会表扬我的！ 一回到家，我就打开袋子请妈妈过目。妈妈摸摸我的小脑袋，“我们家的强强可真的是长大了！不过呢下次买菜一定要注意了……”“注意？注意什么啊？”这下子可把我弄糊涂了。
只见妈妈从袋子里拿出一株青菜，一甩，有很多的小水珠落了下来，接着我学着妈妈的样子，果然甩出好多的水。再一称，呀！两斤也不到，我直呼自己上当了！妈妈仿佛把我看穿了，说：“有水的蔬菜看起来很新鲜，可是称的时候一定要把水分甩干喽！”
I saw my mother take out a plant of green vegetables from the bag, a swing, a lot of small drops of water fell down, and then I learned my mother's appearance, as expected, threw out a lot of water. Again, ah! Two catties are not enough, I call myself cheated! My mother seemed to see through me and said, "vegetables with water look fresh, but they must be dried when weighing!"
原来水分也要占一定的分量，看来真该好好学学生活中的数学了，我以后可要经常接触生活中的数学，要懂得生活，要体验生活。
It turns out that water also accounts for a certain amount. It seems that it's really time to study mathematics in life. In the future, I can often contact mathematics in life, understand life and experience life.
