I don’t want to get behind with my work.

【get】我不想拖延工作。

It's our first performance next week, so we're rehearsing frantically, and I've got behind with my work, but it's worth it.

下周是我们第一次演出，所以我们正在疯狂的排练，我的学业都耽误了，但是值得。

It might sound a bit selfish, but I don't like getting behind with my coursework, and it was a bit of a relief to have a break from Lou's misery.

这听起来可能有点自私， 但我不喜欢我的课程作业落后，从卢的痛苦中解脱出来让我松了一口气。
