travel by train

坐火车旅行

a long train of visitors before the monument

纪念碑前长长的参观队伍

A train of nice recollections runs across my mind when speaking about my college years.

一说起大学时代，我的脑中就闪过一串美好的回忆。

Sports help to train a person’s character.

运动有助于培养人的性格。

The school basketball team is training hard for the league match.

校篮球队正在刻苦训练备战联赛。
