Question

A ground-based system that uses much stronger signals than GPS can find your location in cities and indoors. It is a new positioning system that could compete with GPS to make sure you never lose your directions again.

Instead of satellites, Locata uses ground-based equipment to send a radio signal over a localized area that is a million times stronger on arrival than GPS. It can work indoors as well as outdoors, and the makers claim that the receivers can be shrunk(缩小) to fit inside a regular cell phone. Even the US armies, which invented GPS technology, signed a file last month agreeing to a test of Locata at the White Sands Missile Range in New Mexico.

“This is one of the most important technology developments for the future of the positioning industry,” says Nunzio Gambale, CEO and co-founder of the firm Locata, based in Griffith, Australia.

As for the Locata’s correctness, Christopher Morin of the US Air Force tested it recently at White Sands, and it worked to within 18cm along any axis(轴). Morin said it should be possible to get the exactitude down to 5cm.

The tests were performed in an open desert where GPS also worked beautifully, but its signal was weak—like a car headlight from 20,000 kilometers away—and easily cut off by solid objects(实心的物体). Locata’s signal was far stronger, though not guaranteed to work in a complex urban environment, said David, speaker of the UK’ s General Lighthouse Authorities.

Locata’s technology will face competition in the race to transform indoor navigation. But it could shine in specific areas, Gambale said. Robots with Locata could easily navigate inside buildings without the complex optical(视觉的) systems they need at the moment. And the process that handles correct location data could not only guide you around a mall, railway station or airport, but also take you to the exact shelf in a shop for the product you want. It would be small and cheap enough for smart phones and it should be available within five years—a similar path to the one GPS took on its way towards the world, he said.

A. did the experiment at White Sands last month

B. believed the Locata would help to develop smart robots’ creation

C. doubted whether Locata can work in a complex environment or not

D. was worried about the competition the Locata faced

4.Which of the following can replace the underlined word “exactitude” in Paragraph 4?

A. Accuracy.           B. Speed.

【解析】

试题分析：本文是一篇说明文，介绍一种新的定位系统。

1.C考主旨大意题。第一段" A ground-based system that uses much stronger signals than GPS can find your location in cities and indoors. It is a new positioning system that could compete with GPS to make sure you never lose your directions again."可知，本文要介绍一种新的定位系统。选C。

2.D 考查细节理解题。通过第二段第一句“Instead of satellites, Locata uses ground-based equipment to send a radio signal over a localized area that is a million times stronger on arrival than GPS.”知A正确。根据第二段最后一句“Even the US armies, which invented GPS technology, signed a file last month agreeing to a test of Locata at the White Sands Missile Range in New Mexico ”可知B正确；根据第五段“Locata’s signal was far stronger, though not guaranteed to work in a complex urban environment,”可知C正确；根据最后一段最后一句“It would be small and cheap enough for smart phones and it should be available within five years—a similar path to the one GPS took on its way towards the world, he said.”可知五年之内这种新的定位系统就可以投入使用，所以D错误。故选D。

3.B 考查推理判断题。根据第六段第三句“Robots with Locata could easily navigate inside buildings without the complex optical(视觉的) systems they need at the moment..”就算没有它们本应该需要的复杂的视觉系统，装有Locata的机器人在大楼内更容易操纵。故选B。

4.A 考查猜词义。从“exactitude”查读到第四段第一句“As for the Locata’s correctness, Christopher Morin of the US Air Force tested it recently at White Sands, and it worked to within 18cm along any axis(轴).就Locata的准确率而言，美国航空部队的Christopher Morin最近在White Sands测试，可以在半径18厘米内” 中“correctness”可知，此处指的是准确率。Accuracy准确， 精确；Speed速度； Determination 决心； Length长度。故选A。

5.考查细节理解题。通过第二段第二、三句“the receivers can be shrunk(缩小) to fit inside a regular cell phone”最后一段“It would be small and cheap enough for smart phones and it should be available within five years”可知Locata被装在手机里，五年内可以买到，故进入我们的生活。故选D。

【名师点睛】

推理判断题要求考生根据文章的某个句子、段落、或全文所提供的事实进行逻辑推理，推断出作者没有提到的或没有明说的事实或者可能发生的事情。考查考生透过词语的字面意义去理解作者的言外之意的能力。这类题目包括：推断隐含意义，推断目标读者，推断写法意图，推断观点态度。推理的步骤：1. 通过寻都找到相关信息。2.理解相关信息点的字面意思。3.结合语境进行符合语境的逻辑判断，从而推出作者的言外之意。本题的48题考的是推断隐含意义。根据第六段第三句“Robots with Locata could easily navigate inside buildings without the complex optical(视觉的) systems they need at the moment.”就算没有它们本应该需要的复杂的视觉系统，装有Locata的机器人在大楼内更容易操纵。可知，Locata有助于机器人的生产。
