句子：這個(gè)裝置的目的是使汽車在滑坡時(shí)安全而省油。

誤譯：The device is aimed at making a car safe and petrol-saving when it is landsliding.

正譯：The device is aimed at making a car safe and petrol-saving when it is running downslope.

解釋：landslide 一般當(dāng)名詞用，意思是a mass of earth, rock, etc. that falls down the slope of a mountain，即“山體滑坡”，指自然現(xiàn)象，不是指汽車滑坡。

“滑坡”的第一個(gè)意思是指“地表斜坡上大量的土石在重力作用下整體下滑的自然現(xiàn)象”。英語可以譯為 landslide, landslip。例如：滑坡會(huì)對(duì)建筑物、公路和森林造成很大破壞。Landslide can cause great damages to buildings, highways and forests.

“滑坡”的第二個(gè)意思是指“汽車下坡行駛或順坡下滑”。英語可譯為 to run/slide downslope。如：

今天早晨，這里發(fā)生了汽車滑坡事故。This morning, here occurred an accident in which a car slided downslope.

“滑坡”的第三個(gè)意思是比喻“經(jīng)濟(jì)或成績急劇下降”。英語動(dòng)詞可以譯為 to decline, to slump, to landslide, to go downslope；名詞可以譯為decline, slump, landslide, downslide。例如：由于自然災(zāi)害，這個(gè)地區(qū)的經(jīng)濟(jì)嚴(yán)重滑坡。As a result of natural disasters, there has been a massive decline/landslide in economy in this area.▲（本欄目供稿：王逢鑫教授）
