请教一个英文句子的中文翻译，就一句话，但是看不懂是什么意思，谢谢！

He spent yesterday hidden away in his country retreat.

解答：以上属于双重谓语用法，意思，SPENT 即充当实义动词，有充当连系动词使用，表示一个动作发生时，伴随着另外一个动作，上面句子可以改写成下面句子：

He was hidden away in his country retreat when he spent yesterday
He hid himself away in his country retreat when he spent yesteday

主语：He (他）

谓语：spent （度过）

宾语：yesterday （昨天）

状语：hidden away in his country retreat（躲藏在他家乡下休息寓所里）

句子意思：他是躲在他乡下休息寓所度过了昨天.

他昨天躲在了他乡下的静养地

很高兴为你解答,谢谢

他去山中的休养所过周末

他昨天隐藏在他的国家撤退。

这个应该要结合语境吧。
给个大概的翻译：昨天一整天他都躲在乡下可以撤退的那条小路上
