我有一把尺子，是上学期我得了三等奖获得的。这把尺子只有12厘米，上面画有两部汽车，还有两个车轮。一辆汽车在起跑点上，路边有一排路灯。汽车在路上行驶，就会出现五颜六色的汽车。
I have a ruler. I won the third prize last term. This ruler is only 12 centimeters long. There are two cars and two wheels on it. A car is at the starting point. There is a row of street lights on the side of the road. When the car is on the road, there will be colorful cars.
有一次数学测验，我不知道这是直角还是钝角。我拿起尺子一量，嘿，量出来了。
On one math test, I didn't know if it was a right angle or an obtuse angle. I took the ruler and measured it. Hey, it's out.
转眼间，它成了我的好伙伴。
In a flash, it became my good partner.
