四月到了，天氣也逐漸地變得溫暖了起來。小山這週又恢復了在小區裡跑步，還記得第一次跟小山一起跑步的時候，真的是嚇了自己一跳。小山跑步的耐力是真的非常的強，而且他的速度也一直在提升，剛開始15分鐘跑一大圈，現在只需要8分半就可以跑完，基本上是之前速度的兩倍，進步速度真的是非常的快。
As April comes, the weather is getting warmer and warmer. Xiao Shan resumed running this week. I remember the first time I ran with Xiao Shan, I was really surprised. The endurance of hill running is really very strong, and his speed is improving all the time. Koyama started out doing a lap in 15 minutes, and two weeks later he was doing a lap in eight and a half minutes, almost twice as fast as he had done before. It was a really fast improvement.
