The school even has a track, field, and sports teams.

学校甚至拥有田径队和运动队。

A three laps to the mile course is, therefore, a trifle larger track field than the ordinary one, so that three laps make the mile.

因此，三圈到英里赛道是一个比普通赛道大一点的田径场，所以三圈就是一英里。

The size of the ordinary track field is so laid out that a runner going four times around the track covers distance equivalent to a mile.

普通田径场的布局使得跑步者绕跑道四圈的距离相当于一英里。
