以前,我一直以为学习“最小公倍数”这种知识枯燥无味,整天与“求11和12的最小公倍数”等类似的问题打交道,真是太无聊了,总觉得学习这些知识在生话中没有什么用处。然而,有一件事却改变了我的看法。那是前不久的事情,爷爷和我一起乘坐公共汽车去青少年宫。我们坐的是3路车,快要出发的时候发现,1路车正好和我们同时出发。此时爷爷看着这两路车,突然笑着对我说:“小辉,爷爷出十问题考考你,好不好?”我胸 I used to think that learning about the “least common multiple” is a boring, day-to-day problem with such things as “least common multiple of 11 and 12,” and so on. In no use. However, one thing has changed my mind. It was not long ago, Grandpa and I took the bus to the Youth Palace. We are sitting on the 3-way car, almost starting when found, 1-car just starting with us at the same time. At this point my grandfather looked at these two cars, suddenly smiled and said to me: “Xiaohui, grandfather out of ten questions test you, okay?”
