大年初二那天,我和妹妹随爸妈一起到二姨家拜年。一到二姨家二姨就拿出我们平常最喜欢吃的巧克力给我们,妹妹贪心,一连抓了两把,我也不甘落后的抓了一大把,不过我的一大把也还是没有妹妹的多,因为妹妹有14块,而我只有10块。可是,到了吃饭的时候,我的巧克力居然和妹妹同样多了,都还有8块。怎么回事呢?原来妹妹已经吃掉了6块,而我只吃掉2块。嗯?数学中我们经常会碰到这样的问题呀?
On the second day of the New Year, my sister and I went to the second aunt’s home with my parents. One or two aunt and two aunt took out our usual favorite chocolate to us, my sister greedy, and even caught two, I am not far behind a lot of grabs, but a lot of my or no sister Because my sister has 14, and I only have 10.
