Question

【題目】

What would the world be like if cars could drive themselves? Imagine seeing an empty car passing by on its way to pick up its owner, or a car full of passengers who are reading, listening to music or even sleeping. But none of them are worried about the road ahead.

Well, all of this could be the future of driving. There are several companies, including Google, working on driverless cars. So far, no Google self-driven car has gotten a traffic ticket, bus some of them have been in accidents when other cars hit them.

These cars are now still in the testing stages. But, if the tests are successful, these electric self-driven cars could be put into use very soon.

The cars already have many features（特點(diǎn)）allowing them to take the place of drivers during certain situations. Some features include cars being able to park themselves, or slow down when they notice objects close by. They can also control the speed if there are dangerous conditions.

Scientists and engineers believe, with the help of wireless（無線電的）signals, cameras and GPS, we are now at a stage where creating a safe self-driven car might be possible.

The cause of deadly road accidents is usually careless drivers or dangerous conditions. The self-driven car may be able to prevent these. However, some people do not like the idea. American lawyer Whit Drake, for example, doesn't believe these cars are safe. He thinks that technologies can also be mistakes.

【1】The main purpose of the first paragraph is to _____.

A. make readers wonder about self-driven cars

B. get readers to pay attention to road safety

C. tell readers to keep away from heavy traffic

【2】The testing self-driven cars need _____ energy to run.

A. solar B. nuclear C. electric

【3】From the passage, we know that the testing self-driven cars can already ______.

A, avoid being hit by other vehicles on roads

B. control the speed in dangerous situations

C. turn around when getting near objects

【4】What might make the self-driven cars run safely according to the passage?

a.e-reading b. wireless signals c.cameras d. GPS

A. a, b, c B. a, b, d C. b, c, d

【5】What is Whit Drake's attitude（態(tài)度）toward the safety of the self-driven cars?

A. He has doubt about it

B. He believes it completely

C. He doesn't care about it.

Answer 1

【答案】

【1】A

【2】C

【3】B

【4】C

【5】A

【解析】

試題分析：本文是一篇有關(guān)“無人駕駛汽車”的介紹，文中介紹了無人駕駛車輛的研究歷史，無人駕駛車的原理，現(xiàn)在的研究成果及人們對此的不同態(tài)度等等。

【1】A 主旨大意題。題意：第一自然段的主要目的是什么？A. make readers wonder about self-driven cars使作者想要知道無人駕駛車；B. get readers to pay attention to road safety使讀者注意道路安全；C. tell readers to keep away from heavy traffic告訴讀者遠(yuǎn)離擁擠的交通。第一段描述的是無人駕駛的車輛上的快樂情境，目的是使人們對無人駕駛感興趣，想知道是怎么一回事。故選A。

【2】C 細(xì)節(jié)理解題。題意：測試無人駕駛小車，需要什么能量供其運(yùn)行？A. solar太陽能；B. nuclear核能；C. electric電能。由第三段中的：But, if the tests are successful, these electric self-driven cars could be put into use very soon.可知是“電動無人駕駛車”故選C。

【3】B 細(xì)節(jié)理解題。題意：從短文中，我們知道無人駕駛小車的測試已經(jīng)可以做什么了？A, avoid being hit by other vehicles on roads避免在路上被其他交通工具撞擊；B. control the speed in dangerous situations在危險(xiǎn)的時(shí)候控制速度；C. turn around when getting near objects靠近物體時(shí)轉(zhuǎn)彎。根據(jù)第四段里的：They can also control the speed if there are dangerous conditions.可知在危險(xiǎn)時(shí)，車輛可以自己控制速度。故選B。

【4】C 推理判斷題。題意：根據(jù)短文，什么可以使無人駕駛車輛安全行駛？a.e-reading電子閱讀； b. wireless signals無線電信號；c.cameras相機(jī)；d. GPS定位系統(tǒng)。A. a, b, c；B. a, b, d；C. b, c, d根據(jù)倒數(shù)第二段可知，在無線電，相機(jī)和GPS的幫助下，無人加強(qiáng)的安全行駛成為了可能。故選C。

【5】A 推理判斷題。題意： Whit Drake對無人駕駛小車的安全的態(tài)度是什么？A. He has doubt about it他對此感到懷疑；B. He believes it completely他完全相信；C. He doesn't care about it.他不關(guān)心。由短文最后的句子可知，他不相信這種小車是安全的，科技也會出錯(cuò)。故選A。
