小火车叫乐乐，他每天都会开过一座大山。
山里有一个长长的山洞，每次经过那里，乐乐都会害怕。
一天，乐乐鼓起勇气，决定挑战自己。
他开进了山洞，里面黑漆漆的，什么都看不见。
乐乐心里很紧张，但是他告诉自己：“我一定可以做到！”
于是，他慢慢地、小心地开过去。
突然，前面出现了一点亮光。
乐乐兴奋极了，他知道快要到出口了。
他加快了速度，终于冲出了山洞！
他感到非常自豪，因为他克服了自己的恐惧。
从那以后，每当乐乐经过山洞时，他都会对自己说：“我可以做到！”
他也变得更加勇敢和自信。
The little train is named Leo, and he passes through a big mountain every day.
There is a long tunnel in the mountain, and Leo is always afraid when passing through it.
One day, Leo gathered up his courage and decided to challenge himself.
He entered the tunnel, it was pitch black inside and he couldn't see anything.
Leo was very nervous, but he told himself, "I can do it!"
So, he slowly and carefully moved forward.
Suddenly, a faint light appeared ahead.
Leo was excited, he knew he was close to the exit.
He sped up and finally rushed out of the tunnel!
He felt very proud because he overcame his fear.
Since then, every time Leo passes through the tunnel, he tells himself, "I can do it!"
He has become braver and more confident.
