The two countries have each expelled another diplomat following a round of tit-for-tat expulsions.

在一轮以牙还牙的驱逐行动之后，这两个国家又分别驱逐了一位外交官。

After more than 20 such expulsions, I was asked to leave the school altogether.

这样被逐出了二十多次后，我终于被校方彻底开除。

Even so, the study found that the two groups of teachers had similar rates of student expulsions and suspensions.

尽管如此，本研究发现这两组教师对学生的开除及留校察看的处分情况大致相同。
