我们学习数学的时候,精确是第一要素,1就是1,2就是2,怎么能马虎一点点呢?可是,生活中碰到的实际问题却又常常做不到那么准确.比如说,两个同学站在一起,有人问:“他俩谁胖?谁瘦?”你可能会回答:“这个同学胖一些,那个同学瘦一些.”但是如果再问:“胖一些,胖多少?”或者问:“瘦一些,瘦多少?”这时,就会觉得没法准确地回答了.类似这样的情况,还可以举出不少.比如说,两件毛衣,这件颜色比那件深些,那件颜色比这件浅些;两个人,这个人反应快些,那个人反应慢些等等.平常说话的时候,听的人都能明白这里面的意思,但是如果要求说得十分精确,像颜色深浅、思维快慢这 When we learn mathematics, the first element is accurate, 1 is 1 is 2, how can we careless little? However, the practical problems encountered in life are often not so accurate .For example, two Classmates stood together, someone asked: “Who are they fat? Who thin?” “You may answer: ” This classmate is fatter, that classmate is thinner. “But if ask again: ” Fat some fat “Or ask: ” At this time, will feel unable to accurately answer .And such a situation, you can also cite a lot, for example, two sweaters, which The color of the piece is deeper than the one, and the color is a little lighter than this one; two people, the one who responds faster, the one who responds slowly, etc. The person who listens can understand the meaning of the word, However, if the requirements are very precise, like color depth, thinking fast
