正比例→反比例小时候,我特别不喜欢吃饭,所以在饭桌上我用的是最小的碗,妈妈用的是中碗,爸爸用的则是大海碗。我在家里年龄最小,妈妈比爸爸小几岁,爸爸年龄最大。每个人的年龄与各自的饭碗大小成正比例,这似乎是一条不变的定理。随着时间的推移,我小学毕业进了中学,从此饭量大 Proportionality → Inverse Proportion When I was a kid, I didn’t particularly like to eat, so I used the smallest bowl on the dinner table, my mother used the middle bowl, and my father used the big bowl. I was the youngest at home, my mother was a few years younger than my father, and my father was the oldest. The age of each person is directly proportional to the size of their rice bowl. This seems to be an invariable theorem. As time progressed, I graduated from elementary school to secondary school, and since then I have had a great appetite.
