本文屬于說(shuō)明文，主要介紹了無(wú)人駕駛汽車的工作原理，優(yōu)點(diǎn)以及存在的問題。

【1】句意：此外，計(jì)算機(jī)通常比人類更高效。

根據(jù)“You wouldn’t have to worry about remembering directions to where you’re going.”你不必?fù)?dān)心記住你要去哪里的方向。可知，下文應(yīng)該是說(shuō)計(jì)算機(jī)通常比人類更高效。故選C。

【2】句意：他們也會(huì)比人們更安全地駕駛——他們不受音樂或朋友的影響，他們會(huì)遵守限速，在緊急情況下反應(yīng)更快。

根據(jù)“They would also drive more safely than people.”他們也會(huì)比人們更安全地駕駛�？芍�，在緊急情況下反應(yīng)更快。結(jié)合所給的詞語(yǔ)可知，應(yīng)該選擇quicker；是指：只有在緊急情況下反應(yīng)更快，才會(huì)更安全。故選E。

【3】句意：盡管被機(jī)器驅(qū)動(dòng)可能意味著沒人需要駕照，為每個(gè)人節(jié)省開支，但當(dāng)出現(xiàn)無(wú)司機(jī)汽車時(shí)，許多人會(huì)失業(yè)。

由后面的by a machine可知，前面應(yīng)該是被動(dòng)語(yǔ)態(tài)；結(jié)合所給的選項(xiàng)可知，只有driven是過(guò)去分詞；being driven around by a machine：被機(jī)器驅(qū)動(dòng)。故選B。

【4】句意：公共汽車、出租車和火車司機(jī)以及駕駛教練將變得不必要。

根據(jù)“Although being 3 around by a machine”被機(jī)器驅(qū)動(dòng)。可知，一旦出現(xiàn)了無(wú)人駕駛的汽車，那么公共汽車、出租車和火車司機(jī)以及駕駛教練將會(huì)變得不必要了。故選D。
