落在后面

Several of the runners fell behind in the race.

有几个赛跑者比赛中面。

Why does she always lag behind others when we're out for a walk?

么外出散步时, 她总面?

I trailed on behind, haggard and disheveled.

我疲惫不堪地面，形容憔悴，头发蓬。

In my first month at college I was continually chasing my own tail and being late for everything.

上大学的第一个月我瞎忙一气，还是么都面。

The lame child lagged behind.

那个跛脚的小孩面。
