*第十一篇Virtual Driver
Driving involves sharp eyes and keen ears，analyzing with a brain，and coordination between hands，feet and brain.A man has sharp eyes and keen ears，analyzes through his brain，and maintains coordination between his hands and brains.He can control a fast-moving car with different parts of his body.(1)_ _ Apparently there isn't anyone in the driver's cab，but there is in fact a virtual driver1.This virtual driver has eyes，brains，hands and feet too.The minicameras on each side of the car are its eyes and are responsible for observing the road conditions ahead of it as well as the traffic to its left and right.If you open the boot，you can see the most important part of the automatic driving system:a built-in computer.(2)_ _ _ The brain of the car is responsible for calculating the speeds objects surrounding the car are moving at2,analyzing their position on the road,choosing the right path,and giving orders to the wheel and the control system.
In comparison with the human brain,the virtual driver's best advantage is that it reacts quickly.(3)_ _ However,it takes the world's best racecar driver at least one second to react,and this doesn't include the time he needs to take action.
With its rapid reaction and accurate control，the virtual driver can reduce the accident rate on expressways considerably.In this case,is it possible for us to let it have the wheel3 at any time and in any place?___4___.With its limited ability to recognize things,the car can now only travel on expressways.
The intelligent car determines its direction by the clear lines that mark the lanes clearly and recognizes vehicles according to their regular shapes.___5___.This being the case4,people still have high hopes about driverless cars，and think highly intelligent cars are what the cars of the future should be like5.

答案与解析：
1.D“空1”前面三个句子讲的是真人驾驶员驾驶汽车时脑、眼、耳、手、脚并用，而且要协调配合。“空1”之后话题转入虚拟驾驶员。“空1”之后的第一句“Apparently there isn’t anyone in the driver’s cab……”似来得有些突然。与前面句子接得很生硬。中间应该有个过渡句。选项C就是连接上下文的过渡句。
2.C“空2”前面一句说，如果你打开车身后部的行李箱，你就能看到自动驾驶系统的最重要的部件，嵌入式电脑。“空2”后的句子中的the brain of the car自然是指前句的built-in computer,但接得太突然。选项C的“This is the brain of the car”就把前后句子联系起来了。this指代上一句的built-in comupter。后面句子的The brain of the car是重复选项C中的The brain of the car，显得很自然。所以，C是答案。
3.E“空3”前面一句说，虚拟驾驶员最大的优点是反应快。“空3”后面一句说，最好的赛车手至少要1秒钟才能作出反应。“至少要1秒钟”已经暗示，虚拟驾驶员反应速度要比真人驾驶员快。一找，选项E果然说，虚拟驾驶员只需100毫秒就能作出反应。选项E使上下文的意思完整，因此是答案。
4.A“空4”前面是一个问句，即“在这种情况下，是不是可以不分时间、不分地点都让虚拟驾驶员驾驶汽车?”“空4”的句子应该回答这个问题：“让还是不让?”选项A回答了这个问题，因此是答案。
5.F“空5”前面一句的意思是，"The intelligent car determines its direction by the clear lines that mark the lanes clearly and recognizes vehicles according to their regular shapes."（智能汽车按清晰标出的车道线决定自己的行车方向，靠车辆的常规形状识别其他车辆。）选项F的内容正好相反。上一句说"recognizes"，还有"mark the lanes clearly"，而F说"cannot recognize"，又说"no clear markings"。从意思表达和词汇重复上，都能判断出，F的句子应该出现在“空5”的位置上。
