An intelligent car
5 U- w8 k5 n1 E2 O3 v# ~ CDriving needs sharp eyes, keen ears, quick brain, and coordination between hands and the brain. Many human drivers have all __1__ and can control a fast-moving car. But how does an intelligent car control itself?
5 F' f1 F6 s% r( p: m; U, ^There is a virtual driver in the smart car. This virtual driver has “eyes,”“brains”，“hands” and “feet”，too. The mini-cameras __2__ each side of the car are his “eyes,” which observe the road and conditions ahead of it. They watch the __3__ to the car’s left and right. There is also a highly __4__ driving system in the car. It is the built-in computer, which is the virtual driver’s “brain. ” His “brain” calculates the speeds of __5__ moving cars near it and analyzes their positions. Basing on this information, it chooses the right __6__ for the intelligent cars, and gives __7__ to the “hands”and “feets”to act accordingly. In this way, the virtual driver controls his car.! Y6 _4 s( V7 ^& s
What is the virtual driver’s best advantage? He reacts __8__. The mini-cameras are __9__ images continuously to the “brain”. It __10__ the processing of the images within 100 milliseconds. However, the world’s best drier __11__ needs one second to react. __12__, when he takes action, he needs one more second.* N5 O$ b; a* U, ^* k
The virtual driver is really wonderful. He can reduce the accident __13__ considerably on expressway. In this case. Can we let him have the wheel at any time and in any place? Experts __14__ that we cannot do that just yet. His ability to recognize things is still __15__. He can now only drive an intelligent car on expressways.

) d& F5 U3 q* @+ {% K1 ~. c解析：1.A. 解析：根据all的习惯搭配结构：all + 指示代词， 因此首先排除B(人称代词)。 结合前句内容，空格处的代词应该指代前句中提到的“敏锐的眼睛和耳朵， 反应迅速的大脑， 手和大脑之间的协调”， 因此应该选择指代复数的指示代词these.
8 ~* u/ h; U7 s2 r3 d/ i2.D. 解析：与side 搭配的介词是on.(on the side of.../在...的上面); f4 [$ [) l5 }" j
3.B. 解析：空格所在的句子说“它们观察智能车左右两侧的...”， B(车流)放入空格中最恰当。% @# Q6 `/ ?2 Q. a) Z9 u( _
补充： to:(表示相对的位置)在
, c+ {, m+ d% \; m% [e.g. The village(村庄) lies (位于) to在 the east(东边) of the woods(树林).# Y8 Z* N- y; Y0 F# K% O2 \2 J
4.C. 借助空格所在局部搭配结构“高度...”，直接判断“高度自动化的”搭配通顺，因此C 是答案。, L2 F/ g y1 \" D+ Q
5.B. 解析：B和C都是“彼此， 相互”，互为近义词， 所以相互排除掉; 空格后出现的是复数名词(cars)， 因此B是答案(another修饰可数名词的单数)。 " G+ k% q2 n9 x4 [0 R; g
6.A/D.解析：空格所在的局部机构说“根据这个信息(在其附近移动的汽车的速度和位置)， 它为智能车选择合适的...”, 因此判断A 和D(路线)合适。7 B; ^- ^4 T1 O! `6 Z/ `
7.C.解析：根据空格所在的局部结构(给...给“手”和“脚”， 以使它们做出相应的动作)判断C(指令)是答案。
+ h9 e8 N; w! _' @& }8.A. 解析：空格所在的句子说“他(虚拟司机)...反应”，结合前句内容(什么是虚拟司机最大的优势?)及常识判断A(迅速地)最可能成为答案。
, ]& K; C2 [: d* X7 M+ i; c9.C. 解析：空格所在的句子说“小型照相机连续地把图像...到‘大脑’”， 因此C(发送)放在空格中合适。: x6 \" c! z" {! ?
10.B. 解析：空格所在的句子说“它在100毫秒的时间里...图像的处理”, 根据该句内容判断B(完成)是答案。
3 u5 X4 S9 u. g8 {( ~; b11. A。 解析：B和D是近义短语结构， 因此相互排除掉。 空格所在的句子说“然而， 世界上最好的司机做出反应...需要1秒钟”， 因此判断A(至少)是答案。 第10题和第11题所在的句子把“虚拟司机”和“人类最好的司机”进行反应速度的对比(虚拟司机反应速度快)，显然这是利用具体事实的分析以论证该段开头部分的观点句(He reacts quickly)， 因此进一步肯定第8题的答案是“quickly”。
8 A; V7 c! d7 S5 G+ [* T( X! J1 t1 Z! E- l9 r. r3 D6 X
12.C. 解析：因为前一句已经是however引导的表示“转折关系”的句子， 因此不可能接着又出现however引导的另一转折句，所以首先排除B。 空格位于句首，而且有一个逗号与句子其他部分隔开， 因此空格处应该出现逻辑副词。 A 和D在用作逻辑副词的用法和词义上接近， 因此相互排除， 因此答案为C。 从空格所在句子的句意上看， 该句引出另一信息， 因此从句意上判断也需要“besides ”—引出表示递进关系的句子。 |
