Last evening I was watching the evening news on television. The news was about a prize for scientific 1      . I forgot what it was. The announcer,whose name was Ralph Story,said something that caught my 2      . "All great discoveries," he said? "are made by people be?tween the ages of twenty-five and thirty. " Being a little over thirty myself,I wan?ted to 3        with him. Nobody wants to think that he is past the age of making any discovery. The next day I happened to be in the public library and spent several hours looking 4        the ages of famous people and their discoveries. Ralph was 5      . First I looked at some of the 6        discoveries. One of the earliest discoveries,the 7        experiment that proved that bodies of different weight fall at the same speed,was made by Galileo when he was 26,Madam Curie started her research that 8        to the Nobel Prize when she was 28.        Einstein was 26 when he 9        his world-changing theory of relativity. Well,enough of that. Yet I 10        if those "best years" were true in other 11      . Then how about the field of 12     ?Surely it needs the wisdom of 13 to make a good leader. Perhaps it does,but look when these people 14        their ca?reer. Winston Churchill was elected to the House of Commons at the age of 26.Abraham Lincoln 15        the life of a country lawyer and was elected to govern?ment. At what age? Twenty-five.

  But 16        don't best years come after thirty? After thirty,I 17     ,most people do not want to take risks or try 18        ways. Then I thought of people like Shakespeare and Picasso. The former had wonderful works at the ripe age of fifty,19        the latter was still trying new ways of painting when he was ninety!Perhaps there is still 20        for me.

  [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
