如何理解这句话:"She must have tried to come back to them and got lost ," she added.

“她一定是试图回到他们身边来着却走丢了,”她补充道。

She must have tried to come back to them and got lost ," she added.
must have done这种情态动词+完成形式的用法表示“对过去发生的事情的肯定猜测”
句子大意:“她肯定是想回来的,但迷路了”她补充说道。
温馨提示:情态动词+完成式的用法很多,如:
may have done (对过去发生的事情不肯定的猜测)
should have done(应该做而没有做)
could have done(能够做而没有做)
希望对你有所帮助。

翻译:“她一定是已经尝试过回到他们身边,并且还是走丢了”她补充道.
引号里的应该是虚拟语气,表示推测已经做过某事.
