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.

　　5.highly intelligent cars are what the cars of the future should be like：未來的汽車就應(yīng)該是高度智能化的汽車。

　　B．In the near future， intelligent cars will be put into commercial operation.

　　C．This is the brain of the car.

　　D．But how does an intelligent car control itself?

　　E. It completes the processing of the images sent by the cameras within 100 milliseconds.

　　F．However, it cannot recognize moving people and bicycles on ordinary roads that have no clear markings on them.

　　答案與解析：

　　1. D "空1" 前面三個句子講的是真人駕駛員駕駛汽車時腦、眼、耳、手、腳并用，而且要協(xié)調(diào)配合。"空1"之后話題轉(zhuǎn)入虛擬駕駛員。"空1"之后的第一句 "Apparently there isn't anyone in the driver's cab……"似來得有些突然。與前面句子接得很生硬。中間應(yīng)該有個過渡句。選項 C 就是連接上下文的過渡句。

　　2. C "空2"前面一句說， 如果你打開車身后部的行李箱，你就能看到自動駕駛系統(tǒng)的最重要的部件，嵌入式電腦。"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。選項 C 的 "This is the brain of the car "就把前后句子聯(lián)系起來了。this 指代上一句的 built-in comupter。后面句子的 The brain of the car 是重復選項 C中 的 The brain of the car，顯得很自然。所以，C是答案。

　　3. E "空3"前面一句說，虛擬駕駛員最大的優(yōu)點是反應(yīng)快。 "空3"后面一句說，最好的賽車手至少要1秒鐘才能作出反應(yīng)。"至少要1秒鐘"已經(jīng)暗示，虛擬駕駛員反應(yīng)速度要比真人駕駛員快。一找，選項 E 果然說，虛擬駕駛員只需100毫秒就能作出反應(yīng)。選項 E 使上下文的意思完整，因此是答案。

　　4. A "空4"前面是一個問句，即"在這種情況下，是不是可以不分時間、不分地點都讓虛擬駕駛員駕駛汽車?""空4"的句子應(yīng)該回答這個問題："讓還是不讓?"選項A回答了這個問題，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. "（智能汽車按清晰標出的車道線決定自己的行車方向，靠車輛的常規(guī)形狀識別其他車輛。）選項F的內(nèi)容正好相反。上一句說"recognizes"，還有"mark the lanes clearly"，而F說"cannot recognize"，又說"no clear markings"。從意思表達和詞匯重復上，都能判斷出，F(xiàn)的句子應(yīng)該出現(xiàn)在"空5"的位置上。
