這篇短文給我們介紹的是自動(dòng)駕駛汽車，這種汽車?yán)锇惭b有軟件，可以指導(dǎo)汽車的運(yùn)行。與普通汽車相比，它有很多的好處，如更加安全、環(huán)保、讓殘疾人可以更加輕松地四處活動(dòng)等。但同時(shí)它也有它的不足之處。
【36題詳解】
句意：它可能是百度的一輛自動(dòng)駕駛汽車。根據(jù)下句話Last month, Baidu began to test its self-driving cars on open roads in Beijing.可知，上個(gè)月百度開(kāi)始在北京的開(kāi)放道路上測(cè)試其自動(dòng)駕駛汽車。由此可知，前一句話提到的you see a car going down the road without a driver in Beijing指的就是百度的自動(dòng)駕駛汽車，故應(yīng)選C。
【37題詳解】
句意：自動(dòng)駕駛汽車是在2010年開(kāi)始發(fā)展的。根據(jù)下句話Since then, companies like Tesla, Uber and Baidu have been working to produce and test their own self-driving cars.可知，Since then表示從那以后，所以我們這個(gè)空應(yīng)介紹自動(dòng)駕駛汽車的起源，故應(yīng)選B。學(xué)科*網(wǎng)
【38題詳解】
句意：而且他們比普通的汽車更加的環(huán)保。根據(jù)上句話Self-driving cars are safer than regular cars.可知，這里介紹的是自動(dòng)駕駛汽車比普通汽車的優(yōu)勢(shì)，故應(yīng)選E。
【39題詳解】
句意：但是自動(dòng)駕駛汽車也有它的缺點(diǎn)。根據(jù)下面的文意尤其是The car mistakenly thought that…可知，這里介紹了自動(dòng)駕駛汽車的不足之處，故應(yīng)選D。
【點(diǎn)睛】
這篇短文給我們介紹了一個(gè)科技新發(fā)明—自動(dòng)駕駛汽車，包括它目前的研究情況、它的優(yōu)點(diǎn)和缺點(diǎn)等。文章是科普說(shuō)明文，在文意的理解上有一定的難度，閱讀時(shí)應(yīng)注意把握文章和每一段的中心，注意首尾句。題型是選擇句子補(bǔ)全短文，文章后有五個(gè)選擇項(xiàng)，我們需要把他們放在短文中適當(dāng)?shù)奈恢�。做題時(shí)，應(yīng)先通讀短文，了解文章大意;然后閱讀所給的選項(xiàng)，弄清楚他們的意思，并根據(jù)文意，把他們放到原文中去。注意不用按照題目順序做題，先解決簡(jiǎn)單的、明顯的，最后處理難的，因?yàn)檫x項(xiàng)與空格是一對(duì)一的，所以當(dāng)簡(jiǎn)單的題做出來(lái)的時(shí)候，難題的難度也會(huì)降低。例如第3小題，這個(gè)題目相對(duì)比較簡(jiǎn)單一些，空前的這句話對(duì)比了自動(dòng)駕駛汽車和普通汽車，這句話是順應(yīng)上文而來(lái)的，繼續(xù)對(duì)比兩種汽車，說(shuō)明自動(dòng)駕駛汽車的優(yōu)點(diǎn)，所以應(yīng)選E，這句話與上句話的句式也是一樣的。根據(jù)文意結(jié)構(gòu)可知，到第4題和第5題這兩段里，講述的是自動(dòng)駕駛汽車的缺點(diǎn)了，所以這兩個(gè)選項(xiàng)應(yīng)圍繞這一主題進(jìn)行選擇，如第4小題，這里與上文就是一個(gè)轉(zhuǎn)折的關(guān)系，故應(yīng)選D。
