)汽車，慢慢行駛，直到車到達(dá)正常運(yùn)行的溫度。這樣做會(huì)避免當(dāng)油處于冷、稠狀態(tài)下會(huì)對(duì)引擎帶來(lái)?yè)p傷。另一種辦法就是使用發(fā)動(dòng)機(jī)電加熱器。在發(fā)動(dòng)機(jī)達(dá)到預(yù)定溫度后再起步。對(duì)大多數(shù)現(xiàn)代車輛而言，空轉(zhuǎn)冷的引擎不僅達(dá)不到目的而且還白費(fèi)力氣。另外，當(dāng)你加速時(shí)，只需稍微放開(kāi)一點(diǎn)油門就可以使自動(dòng)變速器升擋。這樣做對(duì)變速器內(nèi)的離合器磨損小。當(dāng)你放開(kāi)油門時(shí)，汽車就很容易用離合器換擋。檢查剎車。剎車系統(tǒng)是汽車最重要的安全特性之一。來(lái)自于剎車的任何噪音，包括尖叫聲、吱嘎聲或咔嗒聲都在警告你剎車可能出問(wèn)題了。讓一位稱職的機(jī)修工檢查一下你的剎車。車輛經(jīng)銷商的維修部是你的首選。清洗車輛。路上的鹽、污泥以及污染可以損壞車身從而產(chǎn)生昂貴的維修費(fèi)用。如果不經(jīng)常清洗，你會(huì)注意到不超過(guò)四年，車門的底部就會(huì)有銹跡。再過(guò)三四年，銹跡會(huì)蔓延到車身底部的部件，比如說(shuō)制動(dòng)管路。如果你不注意車子的清洗，特別是靠近海洋、海灣附近的地方，路上的沙子或早上的露水里都帶有鹽，那么除銹保養(yǎng)會(huì)花上你成千上萬(wàn)元。延長(zhǎng)汽車的壽命，給自己節(jié)約一大筆開(kāi)支的最好辦法就是經(jīng)常對(duì)車子進(jìn)行維修保養(yǎng)。所有汽車生產(chǎn)商就他們所銷售的每一輛車都提供了維修服務(wù)時(shí)刻表。按照這個(gè)時(shí)刻表去做。對(duì)于仍處于保修期內(nèi)的新車，最好的維修地方就是找經(jīng)銷商。對(duì)于過(guò)了保修期的汽車，最好找一家聲望好的店，定期到那里保養(yǎng)你的車輛。ExercisesⅠ.Directions:Answerthefollowingquestionsbrieflyaccordingtothetext.Whatdoesregularcarmaintenancemeantoyou?Accordingtothetext,whyisitnecessarytochangeoilregularly?Whyshouldyougetyourcarofftoagoodstarteverytimeyoudriveit?What’stheuseofchangingtireposition?Andhow?Whatwillhappenifyoudon’twashyourcarregularly?Ifyouwanttoextendthelifeofyourcar,whatisthebestthingtodo?Ⅱ.Directions:Readandjudge.Readthepassageandjudgewhetherthestatementsaretrueorfalse._____T_____1.Irregularmaintenanceofyourcarwillbringyoubiggercostsforrepair._____F_____2.Youneedn’tbothertocheckthefluidsifyourcardoesn’tleakthem._____T_____3.Changingoilonaroutinebasiscansavefuelanddogoodtoyourcarengineaswell._____F_____4.Changingtirepositionisgoodtoanykindoftire,whichhelpstoextendthelifeofyourcar._____T_____5.Ifyoulivenearoceanorgulfshorelines,yourcartendstobecomecorrodedwithinseveralyearswithoutregularcleaning.Ⅲ.Directions:ChooseappropriatewordsfromCol
