Several of the runners fell behind in the race.

有几个赛跑者在比赛中在了。

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

为什外出散步时, 她总在?

I trailed on behind, haggard and disheveled.

疲惫不堪地在，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.

上大学的第一个月瞎忙一气，还是什在。

The lame child lagged behind.

那个跛脚的小孩在了。
