Question

  [2015辽宁朝阳二模] The next generation of robots will be a-ble to see objects,will have a sense of tou?ch,and will make critical decisions.

 Engineering and computer technology are developing artificial vision for robots. With the ability to "see", robots can identify and inspect one specific class of objects out of a stack of different kinds of materials. One robot vision system uses electronic digital cameras containing many rows of lights .sensitive materials to measure the intensity of light and convert the light rays into a range of numbers. The numbers are part of a grayscale system in which brightness is measured in a range of values. One scale ranges from 0        to 15,and another from 0        to 255. The 0        is represented by black. The highest number is white. The numbers in between represent different shades of gray. The computer then makes the calculations and converts the numbers into a picture that shows an image of the object in question. It is not yet known whether robots will one day have vision as good as human vision. Technicians believe they will,but only after years of development. Engineers working on other advances are designing and experimenting with new types of articulated metal hands and fingers,giving robots a sense of touch. Other engineers are writing new programmes allowing robots to make decisions such as whether to discard (丢弃) defective parts in finished products. To do this,the robot will also have to be capable of identifying those defective parts.

 These future robots,assembled with a sense of touch and the ability to see and make decisions,will have plenty of work to do. They can be used to prospect for minerals on the ocean floor or in deep areas of mines too dangerous for humans to enter. They will work as gas station attendants,firefighters,house-keepers,and security personnel. The robot business will continue to grow also. Financial analysts believe this business will soar from a $ 100-mU-lion industry at the start of the 1980s to a $ 5-billion industry in a few years. Anyone wanting to understand the industry of the future will have to know about robots.

16. Why is it so important for robots to be able to "see"?

   A. Because so they can criticize human factory personnel.

   B. Because so they can make critical decisions.

   C. Because so they can completely work as human beings.

   D. Because they have a strong desire.

17. Why will those people interested in industry have to know about robots?

   A. Because robot business will grow rapidly.

   B. Because robots will be very useful.

   C. Because robots will become very popular in industry.

   D. Because they can make a lot of money.

18. What is the meaning of "defective" in the second paragraph?

   A. Having a noticeable or desired effect.

   B. Unquestionable and undoubted.

   C. Imperfect,having serious errors.

   D. Not enough in quantity.

19. What is the best title for this passage?

   A. Future robots will have plenty of work to do

   B. Future robots will see,touch,and think

   C. Engineers to care design new types of cheap ro?bots

   D. Future robots will have visions as good human vi?sion

Answer 1

[文章大意]本文是一篇说明文，主要介绍了未来的机器人可能会像人类一样具有一定的智能。 

16. B细节理解题。根据第一段"The next generation of robots will be able to see objects,will have a sense of touch,and will make critical decisions."可知，机器人能够"看见"很重要，这样它们才能做出重大的决定。 

17. C推理推断题。本文最后一段谈到未来机器人的能力以及它们的广泛用途，并且还用数字说明了机器人产业发展之迅猛，这一切都说明机器人将在未来的产业中占据主导地位，所以对这个行业感兴趣的人将不得不去了解机器人。 

18. C词义猜测题。第二段中倒数第二句话的意思是"其他工程师们正在编写新程序，从而能够让机器人在成品中剔除一些零部件"，由此推测，不会让机器人去剔除好的零部件，肯定是要剔除坏的、有缺陷的零部件，所以defective是"有缺陷的；有瑕疵的"意思。 

19. B主旨大意题。本文第一段就开门见山地说出了本文的中心思想，故选B.
