這篇短文給我們介紹的是自動駕駛汽車，這種汽車里安裝有軟件，可以指導汽車的運行。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等。但同時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，上個月百度開始在北京的開放道路上測試其自動駕駛汽車。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駕駛汽車，故應選C。
【37題詳解】
句意：自動駕駛汽車是在2010年開始發(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，所以我們這個空應介紹自動駕駛汽車的起源，故應選B。學科*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，這里介紹的是自動駕駛汽車比普通汽車的優(yōu)勢，故應選E。
【39題詳解】
句意：但是自動駕駛汽車也有它的缺點。根據(jù)下面的文意尤其是The car mistakenly thought that…可知，這里介紹了自動駕駛汽車的不足之處，故應選D。

這篇短文給我們介紹了一個科技新發(fā)明—自動駕駛汽車，包括它目前的研究情況、它的優(yōu)點和缺點等。文章是科普說明文，在文意的理解上有一定的難度，閱讀時應注意把握文章和每一段的中心，注意首尾句。題型是選擇句子補全短文，文章后有五個選擇項，我們需要把他們放在短文中適當?shù)奈恢谩Ｗ鲱}時，應先通讀短文，了解文章大意;然后閱讀所給的選項，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，先解決簡單的、明顯的，最后處理難的，因為選項與空格是一對一的，所以當簡單的題做出來的時候，難題的難度也會降低。例如第3小題，這個題目相對比較簡單一些，空前的這句話對比了自動駕駛汽車和普通汽車，這句話是順應上文而來的，繼續(xù)對比兩種汽車，說明自動駕駛汽車的優(yōu)點，所以應選E，這句話與上句話的句式也是一樣的。根據(jù)文意結構可知，到第4題和第5題這兩段里，講述的是自動駕駛汽車的缺點了，所以這兩個選項應圍繞這一主題進行選擇，如第4小題，這里與上文就是一個轉折的關系，故應選D。
