我有一把尺子，是上學(xué)期我得了三等獎獲得的。這把尺子只有12厘米，上面畫有兩部汽車，還有兩個車輪。一輛汽車在起跑點上，路邊有一排路燈。汽車在路上行駛，就會出現(xiàn)五顏六色的汽車。

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.

有一次數(shù)學(xué)測驗，我不知道這是直角還是鈍角。我拿起尺子一量，嘿，量出來了。

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.

轉(zhuǎn)眼間，它成了我的好伙伴。

In a flash, it became my good partner.
