Few things .... are tucked away .....新概念41课的其中一段，TUCKED 为什么是过去式？不是一般时？

Few things could be more impressive than the peace that descends on deserted city streets at weekends when the thousands that travel to work every day are tucked away in their homes in the country.新概念41课的其中一段，TUCKED 为什么是过去式？不是一般时？
thousands that travel to work every day are tucked away in their homes in the country
这句话的意思不是说数以千计每天坐长途车上班的都回到乡村的家里吗？是那些人自己主动回家，为什么会用被动语态？？ tucked之前是ARE，所以不是过去式，而且课文的翻译这里的TUCK AWAY in their homes是回家的意思不是被盖被子，回家是他们主动的啊，go home的意思，为什么会是ed的被动式？

Answer 1

意思是说这些人在家里盖好被子(be tucked away)以后，世界就清净了。。。
