植树节那天，老师带我们到山脚下种树。
On tree planting day, the teacher took us to the foot of the mountain to plant trees.
我一会儿挖坑，可是，挖的坑太浅。我一会儿提水，可是，我一个人提不动。搞的我手忙脚乱，满头大汗。可是，树还是没有种好。急得我像热锅里的蚂蚁。
I'll dig a hole later, but it's too shallow. I'll carry water later, but I can't carry it alone. I was so busy and sweaty. However, the trees are still not planted well. I'm like an ant in a hot pot.
这时候，我看见丁丁、冬冬也没有种好树，东张西望的。我说：“我们合作种树吧。”
At this time, I saw Dingding and Dongdong didn't plant good trees, looking around. I said, "let's plant trees together."
看，我们种的多认真呀！我们一块儿挖坑，一块儿提水，一块儿种树苗……
Look, how seriously we planted it! We dig pits, carry water and plant saplings together
不一会儿，我们就种了三棵树，老师过来了，高兴地说：“你们为什么种的这么快，又这么好？”
Soon, we planted three trees. The teacher came and said happily, "why do you plant so fast and so well?"
我们异口同声地说：“我们是合作种树的。”
"We are cooperative in planting trees," we said in unison
老师摸了摸我们的脑袋瓜，笑了。
The teacher touched our brains and smiled.
