    The human brain contains 10 thousand million cells and each of these may have a thousand connections. Such enormous numbers used to discourage us and cause us to dismiss the possibility of making a machine with human-like ability, but now that we have grown used to moving forward at such a pace we can be less sure. Quite soon, in only 10 or 20 years perhaps, we will be able to assemble a machine as complex as the human brain, and if we can we will. It may then take us a long time to render it intelligent by loading in the right software (软件)or by altering the architecture but that too will happen.

    I think it certain that in decades, not centuries, machines of silicon (硅) will arise first to compete and then do better than their human ancestors. Once they do better than us they will be capable of their own design. In a real sense they will be able to reproduce themselves. Silicon will have ended carbon's long control. And we will no longer be able to claim ourselves to be the finest intelligence in the known universe.

    As the intelligence of robots increases to match that of humans and as their cost declines through economies of scale we may use them to improve environments. Thus, deserts may bloom and the ocean beds be mined. Further ahead, by a combination of the great wealth this new age will bring and the technology it will provide, the construction of a vast, man-created world in space, home to thousands or millions of people, will be within our power.

    Kinsey French has taught children with Down syndrome(唐氏综合征) for the past three years. The teacher of 1education at the Christian Academy's Providence School, developed a(n) 2with her students in her first year. That was 3when it came to her wedding day, she invited the class to 4her wedding party as flower girls and ring bearers. "They were like a 5to me," Kinsey told WLKY about the students, 6from seven to eleven years old. "So I knew I couldn't have this important day7them, my lovely 'kids'."

    Kinsey's now-husband, Josh, was 8too — in fact, knowing how much it would mean to her, he 9proposed (求婚) to her in front of the class. The wedding went10on the Internet after photographer Lang Thomas Leichhart 11on his Facebook photos of Kinsey in her wedding dress, 12by her students."The scene of their being together was so moving that I was brought to 13many times during the day," he told CNN. "You can tell how14she is to these kids."

    And while the children loved 15their wedding responsibilities and posing for photos, they said that their 16of the night was the dancing. For Kinsey, it was making 17that would last a lifetime. "It was so exciting," she told WLKY. "It was18for Josh and me just to have them as a19of the day, and have them come and 20with us."

    There is no doubt that many parents want to mold (塑造)their child to be better, faster, smarter and more skilled. Even though human parents can't do that, a robot that builds its own children can. Scientists at the University of Cambridge in England have created a mother robot that not only creates its own children, but tests out their performance.

    The mother robot analyzes(分析)the performance of each of the “children” it creates, and passes down good characters to the next generation

    For example, as the mother creates them and puts them to work, she measures how they're behaving, and she uses data from this behavior to create the next generation of robots.

    The mother robot can actually build hundreds of child robots and see the performance of these child robots. And if their performance is good, keep their design for the next generation. And if bad, just let it go.

    “We program the robots based on some functions that define(规定)the reward the robots are going to get, depending on the construction that they make. They cannot change their own reward. For the child robot, the longer the distance the robot walks, the better the reward it receives,” said Fumiya Iida, the lead researcher.

    After several generations, the “children” were running twice as fast.

    “The mother robot produced 500 robots to see which one is good and which one is bad,” said Iida.

    The researchers believe that the machines can be used in a car factory, for example, where robot cameras examine each ear in production line, find out any mistakes, and then design a better car.

    Mr. Turner turned over in bed from time to time in last night, for he was so excited that he could not fall sleep. Yesterday morning, he went to a big gardening company, knowing as Green Fingers, for the interview. Mr. Turner, who liked to help his grandfather grew flowers in the garden, looking forward to the job offered by the company. When he got the company, he found there were many people waiting and he had no ideas whether he could get the job. While waiting, he helped the workers there to remove the fallen trees and clear the road. Luckily, he was the only one who finally got the job, so the manager decided to give the job to whomever he believed was helpful.

The electricity last night，for the workers were examining the electric wires.(cut)
