共享题干题根据下列材料，回答题 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 (协调) between his hands and brains. He can control a fast-moving car with different parts of his body. （46 ）Apparently there isn't anyone in the driver's cab (驾驶室), but there is in fact a virtual driver. 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 (行李箱), you can see the most important part of the automatic driving system: a built-in computer. （47） The brain of the car is responsible for calculating the speeds objects surrounding the car are moving at, 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. （48 ）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 drive at any time and in any place? （49） 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. （50 ）This being the case, people still have high hopes about driverless cars, and think highly intelligent cars are what the cars of the future should be like.1.[不定向选择题]________________A.Experts say that we cannot do that just ye B.In the near future, intelligent cars will be put into commercial operatio C.This is the brain of the ca D.But how does an intelligent car control itself ?E.It completes the processing of the images sent by the cameras within 100 millisecondF.However, it cannot recognize moving people and bicycles on ordinary roads that have no clear markings on theABCDEF确定 2.[不定向选择题]________________A.Experts say that we cannot do that just ye B.In the near future, intelligent cars will be put into commercial operatio C.This is the brain of the ca D.But how does an intelligent car control itself ?E.It completes the processing of the images sent by the cameras within 100 millisecondF.However, it cannot recognize moving people and bicycles on ordinary roads that have no clear markings on theABCDEF确定

1.参考答案：F
参考解析：空白处前面的句子讲“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”，空白处后面句子讲“如果是这种情况，人们对无人驾驶的汽车还有更高的期待”。“这种情况”指代的就是前面的句子，因而空白处填入的应当是有关汽车辨识的问题，而选项F(但是，它不能识别平时路上那些没有标志的移动的人或自行车)中的recognize和marking等则与前面的句子表现出一致性。
2.参考答案：A
参考解析：空白处的前面一句讲到“让虚拟司机在任何时间和任何地点驾驶是不是可能呢?”，空白处后一句提到“因为辨认东西的能力有限，智能汽车只能在高速路上行驶”，所以空白处应该填入的是否定随时随地驾驶的内容，因而答案为A(专家说我们还不能那样做)为正确答案。?3.[不定向选择题]________________A.Experts say that we cannot do that just ye B.In the near future, intelligent cars will be put into commercial operatio C.This is the brain of the ca D.But how does an intelligent car control itself ?E.It completes the processing of the images sent by the cameras within 100 millisecondF.However, it cannot recognize moving people and bicycles on ordinary roads that have no clear markings on theABCDEF确定
