Question

【題目】Thirteen vehicles lined up last March to race across the Mojave Desert, seeking a million in prize money. To win, they had to finish the 142-mile race in less than 10 hours. Teams and watchers knew there might be no winner at all, because these vehicles were missing a key part －drivers.

DARPA, the Defense Advanced Research Projects Agency, organized the race as part of a push to develop robotic vehicles for future battlefields. But the Grand Challenge, as it was called, just proved how difficult it is to get a car to speed across an unfamiliar desert without human guidance. One had its brake lock up in the starting area. Another began by throwing itself onto a wall. Another got tied up by bushes near the road after 1.9 miles.

One turned upside down. One took off in entirely the wrong direction and had to be disabled by remote control. One went a little more than a mile and rushed into a fence; another managed to go for six miles but stuck on a rock. The “winner,” if there was any; reached 7.8 miles before it ran into a long, narrow hole, and the front wheels caught on fire.

“You get a lot of respect for natural abilities of the living things,” says Reinhold Behringer, who helped design two of the car-size vehicles for a company called Sci-Autonics. “Even ants can do all these tasks effortlessly . It’s very hard for us to put these abilities into our machines.”

The robotic vehicles, though with necessary modern equipment such as advanced computers and GPS guidance, had trouble figuring out fast enough the blocks ahead that a two-year-old human recognizes immediately, Sure, that very young child, who has just only learned to walk, may not think to wipe apple juice off her face, but she already knows that when there’s a cookie in the kitchen she has to climb up the table, and that when she gets to the cookie it will taste good. She is more advanced, even months old, than any machine humans have designed.

【1】Watchers doubted if any of the vehicles could finish the race because .

A．they did not have any human guidance

B．the road was not familiar to the drivers

C．the distance was too long for the vehicles

D．the prize money was unattractive to the drivers

【2】DARPA organized the race in order to .

A．raise money for producing more robotic vehicles

B．push the development of vehicle industry

C．train more people to drive in the desert

D．improve the vehicles for future wars

【3】From the passage we know “robotic vehicles” are a kind of machines that .

A．can do effortlessly whatever tasks living thing can

B．can take part in a race across 142 miles with a time limit

C．can show off their ability to turn themselves upside down

D．can move from place to place without being driven by human beings

【4】In the race, the greatest distance one robotic vehicle covered was .

A．a(chǎn)bout eight miles B．six miles

C．a(chǎn)lmost two miles D．a(chǎn)bout one mile

【5】In the last paragraph, the writer implies that there is a long way to go .

A．for a robotic vehicle to finish a 142-mile race without any difficulties

B．for a little child who has just learned to walk to reach the cookie on the table

C．for a robotic vehicle to deal with a simple problem that a little child can solve

D．for a little child to understand the importance of wiping apple juice off its face

Answer 1

【答案】

【1】A

【2】D

【3】D

【4】A

【5】C

【解析】

試題分析:這是一篇科普說明文，介紹了無人駕駛車輛的特點(diǎn)。

【1】A 細(xì)節(jié)理解題。根據(jù)第一段最后“because these vehicles were missing a key part －drivers.”可知因?yàn)檫@些賽車沒人駕駛。故選A。

【2】D推理判斷題。根據(jù)第二段的第一句話“organized the race as part of a push to develop robotic vehicles for future battlefields.”可知DARPA組織這次比賽是為了推動(dòng)發(fā)展遙控車運(yùn)用于將來的戰(zhàn)爭中。故選D。

【3】D 推理判斷題。根據(jù)文章第一到三段可知 “robotic vehicles” 是一種無人駕駛的遙控車。故選D。

【4】A推理判斷題。根據(jù)二三兩段可知，這些無人駕駛車不太好控制，經(jīng)常出現(xiàn)問題，其中最好的距離是7.8英里。故選A。

【5】C 推理判斷推。根據(jù)最后一段內(nèi)容可知，無人駕駛車輛有必備的現(xiàn)代設(shè)備，但是也有辨認(rèn)缺陷，然而就像嬰兒學(xué)會(huì)夠到桌上的糖一樣，無人駕駛車輛也會(huì)處理好一些簡單的問題的。
