生活英语|overnight bus 卧铺客车

Two traffic accidents claimed the lives of 48 people on Sunday, renewing concerns over the safety of overnight buses and vans carrying children.

周日发生的两起交通事故致使48人丧生，第三引发大家对于卧铺客车和搭载儿童汽车安全的关注。

Overnight bus也叫sleeper bus，就是陕西延安事故中涉及的卧铺客车。这种客车为double-decker bus（双层客车），由于是long distance bus（长途客车），乘客需要在车上过夜，所以也叫overnight bus。

追尾多用rear-end表示，譬如：The truck was rear-ended by a sleeper^{1 bus.（那辆货车被一辆卧铺客车追尾了。）追尾事故则可用rear-end collision来表示。}
