夏天到了，小猴要去田里运西瓜。小猴走到树林里去用斧头砍倒了一棵最大的树，他在树林之间找了一片平地，把树削成一片一片的，做成方形的样子，在用钉子把木板连在一起。这样，就做成了一个漂亮的小车。
When summer comes, little monkey will go to the fields to transport watermelon. Little monkey went to the forest and cut down the biggest tree with an axe. He found a flat ground between the trees, cut the trees into pieces and made them into squares, and connected the boards with nails. In this way, a beautiful car is made.
小猴做了一双三角形的轮子，可是怎么也推不动。小猴心想：三角形的轮子既然推不动，那什么形状的轮子才能一直滚动呢？
The little monkey made a pair of triangular wheels, but could not push them. The little monkey thought: since the triangle wheel can't be pushed, what shape of wheel can keep rolling?
最后，小猴认真思考，他终于想到了！小猴又做了一对圆形的轮子安在车上，推了推，果然推得动。小猴高兴极了。小猴推着小车子去田里运西瓜了！
At last, the little monkey thought seriously, and finally he thought of it! The little monkey made a pair of round wheels and put them on the car. He pushed them, and they could move. The monkey is very happy. Little monkey pushed his little car to carry watermelon in the field!
从此以后，小猴做什么事都动脑筋、仔细想。
From then on, little monkey thought about everything carefully.
