2017職稱英語(yǔ)理工類B級(jí)完形填空及翻譯模擬
職稱英語(yǔ)考試完形填空作為一種傳統(tǒng)題型，在職稱英語(yǔ)考試中也占有重要的地位。下面是yjbys網(wǎng)小編提供給大家關(guān)于職稱英語(yǔ)理工類B級(jí)完形填空及翻譯模擬，希望對(duì)大家的備考有所幫助。
Car Thieves Could Be Stopped Remotely(遠(yuǎn)程制止偷車賊)
Speeding off in a stolen car, the thief thinks he has got a great catch. But he is in a nasty surprise. The car is fitted with a remote immobilizer, and a radio signal from a control center miles away will ensure that once the thief switches the engine off, he will not be able to start it again.
For now, such devices are only available for fleets of trucks and specialist vehicles used on construction sites. But remote immobilization technology could soon start to trickle down to ordinary cars, and should be available to ordinary cars in the UK in two months.
The idea goes like this. A control box fitted to the car incorporates a miniature cellphone, a microprocessor and memory, and a GPS satellite positioning receiver. If the car is stolen, a coded cellphone signal will tell the unit to block the vehicle’s engine management system and prevent the engine being restarted.
There are even plans for immobilizers that shut down vehicles on the move, though there are fears over the safety implications of such a system.
In the UK, an array of technical fixes is already making life harder for car thieves. “The pattern of vehicles crime has changed,” says Martyn Rand all of Thatcham, a security research organization based in Berkshire that is funded in part by the motor insurance industry.
He says it would only take him a few minutes to teach a novice how to steal a car, using a bare minimum of tools. But only if the car is more than 10 years old.
Modern cars are a far tougher proposition, as their engine management computer will not allow them to start unless they receive a unique ID code beamed out by the ignition key. In the UK, technologies like this have helped achieve a 31 per cent drop in vehicle-related crime since 1997.
But determined criminals are still managing to find other ways to steal cars. Often by getting hold of the owner’s keys in a burglary. In 2000, 12 per cent of vehicles stolen in the UK were taken by using the owner’s keys, which doubles the previous year’s figure.
Remote-controlled immobilization system would put a major new obstacle in the criminal’s way by making such thefts pointless. A group that includes Thatcham, the police, insurance companies and security technology firms have developed standards for a system that could go on the market sooner than the customer expects.
遠(yuǎn)程制止偷車賊
超速駕駛在偷來(lái)的汽車?yán)铮弟囐\以為自己大獲全勝。但是他馬上就會(huì)又驚又惱。車上已經(jīng)被裝了遠(yuǎn)程制動(dòng)裝置，一個(gè)幾英里以外的控制中心發(fā)來(lái)的無(wú)線信號(hào)將確保盜賊一旦啟動(dòng)引擎，他就不能再次發(fā)動(dòng)汽車了。目前，這種裝置只用于卡車隊(duì)或者用于建筑工地的特殊車輛上。但是遠(yuǎn)程制動(dòng)技術(shù)很快就會(huì)逐步應(yīng)用到普通汽車上。并且應(yīng)該在兩個(gè)月之內(nèi)用在英國(guó)的普通汽車上。
計(jì)劃是這樣的。把一個(gè)集合有微型無(wú)繩電話，微量處理器，存儲(chǔ)器以及全球定位系統(tǒng)的衛(wèi)星接收器的控制盒子安裝在汽車上。如果汽車被盜，一個(gè)被編碼的無(wú)繩電話信號(hào)就會(huì)告訴這個(gè)裝置停止車輛引擎控制系統(tǒng)來(lái)阻止引擎再次被啟動(dòng)。
甚至還有一些人主張計(jì)劃將制動(dòng)裝置裝在運(yùn)行著的車輛上，可是這樣一來(lái)人們就會(huì)擔(dān)心這個(gè)系統(tǒng)的安全性。
在英國(guó)，一系列的技術(shù)裝置已經(jīng)讓盜車賊步履維艱了。瑪丁蘭多來(lái)自位于貝克郡的一個(gè)出汽車保險(xiǎn)工業(yè)投資成立的名為撒策姆的安全研究機(jī)構(gòu)，他說(shuō)，“車輛盜竊的手法已經(jīng)有所改變。”他還聲稱只要是 10年以上的汽車，他就能用幾樣簡(jiǎn)單的工具在幾分鐘之內(nèi)教會(huì)一個(gè)新手怎樣偷車。
現(xiàn)代車卻遠(yuǎn)沒(méi)有這么簡(jiǎn)單，因?yàn)樗鼈兊囊婀芾碛?jì)算機(jī)裝置只有接收到一個(gè)獨(dú)一無(wú)二的由點(diǎn)火鑰匙發(fā)送過(guò)來(lái)的身份密碼才可以啟動(dòng)汽車。自 1997年以來(lái)，在英國(guó)，技術(shù)人員已經(jīng)利用此項(xiàng)技術(shù)幫助減少了 31%的涉及車輛犯罪案。
但是不死心的盜賊們卻還在一直想方設(shè)法偷車。例如很多時(shí)候，他們?cè)谝估锉I走主人的汽車鑰匙進(jìn)而偷車。在 2000年，英國(guó) 12%的車輛被盜案是由于主人的鑰匙被盜，這個(gè)數(shù)字比前一年增長(zhǎng)了 1倍。
遠(yuǎn)程控制的制動(dòng)系統(tǒng)給盜賊設(shè)置了一個(gè)全新的障礙。包括撒策姆、公安部門、保險(xiǎn)公司以及安全技術(shù)公司在內(nèi)的一個(gè)群體已經(jīng)為體系開(kāi)發(fā)出了一些標(biāo)準(zhǔn)，它們將比顧客所預(yù)期的更早地被很快推廣到市場(chǎng)上。
