◆語(yǔ)篇導(dǎo)讀

隨著科技的日新月異和人類(lèi)生活的大幅改善，越來(lái)越多的便捷的高科技產(chǎn)品問(wèn)世了，“無(wú)人駕駛汽車(chē)”就是其中的一種。雖然此項(xiàng)新技術(shù)還處于研發(fā)之中，但很多人對(duì)其寄予厚望，然而我們也應(yīng)該清醒地意識(shí)到：凡事都有兩面性，“無(wú)人駕駛汽車(chē)”給人們帶來(lái)的更多的是便利還是災(zāi)難？

Have you ever seen a car without a driver？ It sounds crazy，but these computer-driven driverless cars will soon be filling roads near you.Companies like Google and Tesla have been inventing and testing these cars，and the technology is there—they just need to see if they’re worth the money，work out insurance issues（保險(xiǎn)問(wèn)題），and run final tests to check if they can run with human-driven cars on the road.

So how do they work？The cars have sensors all around which can find other cars and obstacles in the road.Sensors on the wheels also help when parking，so the car knows how far it is from the kerb or other parked cars.Road signs are read by cameras，and satellite navigation systems are used so the car knows how to get to your destination.All you have to do is type in the address！ Finally，a central computer system takes in all the infor-mation it receives from the sensors and cameras and processes this to work out when to accelerate，brake and turn.

Sound like your idea of heaven？ Sitting back，looking out of the windows and even watching a film or reading a book while ‘driving’would be possible with this new technology.You wouldn’t have to worry about remembering directions to where you’re going.In addition（此外），they would also drive more safely than people.

However，there are many shortcomings of driverless cars.If a child ran into the road，would the computer choose to hit the child or turn suddenly and possibly kill the car’s passengers？ In addition，some legal problems will need solving.Should children，or drunk people，be allowed in a driverless car by themselves？Or would there need to be a responsible adult with a driving license in the car at all times？

◆典句賞析

1.It sounds crazy，but these computer-driven driverless cars will soon be filling roads near you.這聽(tīng)上去很瘋狂，但是這種電腦駕駛的“無(wú)人駕駛汽車(chē)”將會(huì)遍及我們的周?chē)?/p>

sound這里作為連系動(dòng)詞，形容詞crazy作其表語(yǔ)；在后一個(gè)分句中，these computer-driven driverless cars是句子的主語(yǔ)。

【即時(shí)嘗試】這聽(tīng)上去很可笑，但這是事實(shí)。

2.All you have to do is type in the address！你所要做的就是輸入地址。

句子中的you have to do是定語(yǔ)從句，修飾先行詞all，關(guān)系代詞that在從句中作賓語(yǔ)，已經(jīng)被省略。

【即時(shí)嘗試】你所要做的就是更加努力地學(xué)習(xí)。

3.Or would there need to be a responsible adult with a driving license in the car at all times？或者是否需要有駕照并有責(zé)任感的成人一直坐在這種車(chē)上？

there would need to be...是there be句型，意為“將有必要……”，其中need是實(shí)義動(dòng)詞；at all times是常見(jiàn)的介詞短語(yǔ)，意為“一直，始終”。

【即時(shí)嘗試】這將有必要讓他來(lái)一趟，解釋他的理由。

譯文助讀

你見(jiàn)過(guò)無(wú)人駕駛的汽車(chē)嗎？這聽(tīng)上去很瘋狂，但是這種電腦駕駛的“無(wú)人駕駛汽車(chē)”將會(huì)遍及我們的周?chē)?。像谷歌和特斯拉這樣的公司一直在研發(fā)和測(cè)試這種汽車(chē)，此種技術(shù)已出現(xiàn)——他們只需看看是否有價(jià)值、涉及的相關(guān)保險(xiǎn)問(wèn)題，以及做最后的測(cè)試來(lái)檢驗(yàn)這種汽車(chē)是否能與人工駕駛的車(chē)輛在公路上并行。

那么這種汽車(chē)是怎么工作的呢？車(chē)全身安裝有能夠探測(cè)路上每個(gè)方向的車(chē)輛或障礙物的傳感器，安裝在車(chē)輪上的傳感器在停車(chē)時(shí)也能起作用，因此車(chē)能感知到它距離道沿或其他所停的車(chē)的距離。路標(biāo)上裝有攝像頭，運(yùn)用衛(wèi)星巡航系統(tǒng)，所以“無(wú)人駕駛汽車(chē)”知道怎樣到達(dá)目的地。乘坐人所要做的就是輸入地址，最后，一臺(tái)中樞電腦系統(tǒng)吸收傳感器和攝像機(jī)傳來(lái)的全部信息，加工后輸出加速、剎車(chē)和轉(zhuǎn)向燈等指令。

是不是聽(tīng)上去像是天方夜譚？坐在后排，乘坐人可以領(lǐng)略窗外的風(fēng)景，甚至看電影或看書(shū)，而汽車(chē)在新科技的操縱下行駛，你不必?fù)?dān)心你辨不清方向。此外，它的駕駛比人類(lèi)更安全。

但“無(wú)人駕駛汽車(chē)”還有諸多不足：例如，如果行駛途中突然路上有名小孩，電腦是選擇撞上小孩呢？還是急轉(zhuǎn)彎呢？如果急轉(zhuǎn)彎，這有可能對(duì)乘坐人造成傷害。另外還有一些法律問(wèn)題需要解決——小孩子或者醉酒者是否可以獨(dú)自乘坐“無(wú)人駕駛汽車(chē)”？是否需要有駕照的并有責(zé)任感的成人一直坐在這種車(chē)上？
