5. 座臥轉(zhuǎn)換動(dòng)車
bullet train with fold-up beds

請(qǐng)看例句：

China has developed a bullet train that can convert its sleeping berths to seats to meet demand for around-the-clock operations.
我國已研制出一種具有"座臥轉(zhuǎn)換"功能的動(dòng)車，以滿足全天候運(yùn)營的需求。

近日，兩列CRH5E動(dòng)車組在中車長春軌道客車公司下線(come off the assembly line at the CRRC Changchun Railway Vehicle Co)。這種動(dòng)車的車頭采用黑白相間(black-and-white)的設(shè)計(jì)，就像熊貓的黑眼圈，因此CRH5E動(dòng)車組也被稱為"熊貓動(dòng)車組"(Panda bullet trains)，其最高時(shí)速達(dá)250公里(a maximum speed of 250 km per hour)。

據(jù)介紹，作為國內(nèi)唯一一款可以在極寒和狂風(fēng)條件下運(yùn)行(run in extreme cold and in heavy winds)的臥鋪動(dòng)車組(bullet trains with sleeper seats)，CRH5E具有許多得天獨(dú)厚的技術(shù)優(yōu)勢(shì)(have a number of unique technological advantages/edges)。首先，它具備簡潔實(shí)用的"座臥轉(zhuǎn)換"功能(the function of converting sleeping berths to seats)。CRH5E動(dòng)車組共有16節(jié)車廂(carriages)，其中13節(jié)車廂配備了既有臥鋪又有座位的包廂(be equipped with compartments with both beds and seats)。用于夜間運(yùn)營的床鋪在白天可折疊成座位(the beds for night operations can be folded into seats during the daytime)。

其次，CRH5E是以目前運(yùn)行在哈大線(the Harbin-Dalian railway line)和蘭新線(the Lanzhou-Xinjiang railway line)上的高寒動(dòng)車組為技術(shù)基礎(chǔ)研發(fā)的臥鋪動(dòng)車組，因而繼承了耐高寒、阻冰雪、抗風(fēng)沙的特點(diǎn)。據(jù)悉，這款動(dòng)車組可在氣溫低至零下40℃的環(huán)境下運(yùn)行(run in temperatures as low as -40 ℃)；此外，這種動(dòng)車上電子功能齊全，乘客不必再為手機(jī)沒電或無法上網(wǎng)發(fā)愁。據(jù)報(bào)道，每節(jié)車廂內(nèi)都設(shè)有Wi-Fi天線和插座，乘客可連接Wi-Fi(connect to Wi-Fi)隨時(shí)上網(wǎng)，還可以利用包廂內(nèi)安裝的插座或USB插口為電子設(shè)備充電(charge electric devices with installed sockets or USB ports)。
