落在后面

Several of the runners fell behind in the race.

有几赛跑者在比赛中落在了。

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

为什么外出散步时, 她总落在?

I trailed on behind, haggard and disheveled.

疲惫不堪地落在，形容憔悴，头发蓬。

The lame child lagged behind.

那跛脚的小孩落在了。

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

上大学的月瞎忙气，还是什么都落在。
