The three youths leaned over the metal rails along the sea-wall and watched a few fishermen pull in their nets. About thirty metres away, a boat pulled alongside the slippery steps leading  36  to the sea.
“Hey, look!” exclaimed Rahim. “Those two men are  37  heavy rocks. I thought we no longer do muscle labour in this technological  38  . ”
“They are  41  laborers who know how to spread the weight of the rocks they  42  . See how the man positions the rock just at the slope of his  43  . Some of the rock’s weight is set  44  his head, some on the right hand and some on the left hand. His body isn’t bent. His legs are well  45   . ”
“You’re right, Josh. He may have a small build.   46    he certainly well knows his job. Dear me! And to think we have been studying   47   ! ” Rahim thought about all that was happening. Suddenly, he said, “Technology won’t   48   the human being completely, it appears.”
“I don’t think it will. ”  49  Joshua. “You can harvest a crop of potatoes or wheat with one of those large, multi-purpose tractors, but you  50   use that equipment to harvest lea leaves and tomatoes, will you?”
“You can get a computer to   51   multiple-choice assessments, but you cannot get the computer to produce of assess essays, can you?” asked Michael.
“Well, the washing machine leaves my shirt collar quite as  52   as ever --- that’s domestic technology for you! ” said Rahim.
“One day, perhaps, there won’t be anybody   53   who can carry a large rock the way those men do. It’s not going to be a very  54   world, I’m afraid.” Sighed Michael.
“You’re too much of a pessimist (悲观主义者)，Mike.” Said Joshua. “  55  will always be other things that will make the world exciting. ”

     Four out of five parents worry that their children will become addicted to Facebook, according to a study.

    Eighty percent believe social networking sites such as Facebook and Twitter have the ability to take over their children’s lives. One in three parents, meanwhile, believe the Internet has the power to ‘rewire’ brains(“改装”大脑)without a person’s knowledge and think their children are in danger from the web.

    The extraordinary findings come from a poll of 1, 000 parents carried out by the Nominet Trust, an organization that promoted Internet projects which address social disadvantages.

    However, Nominet said their findings fly in the face of neurological(神经学上的) evidence. The Trust worked with neuroscience and education expert Dr Paul Howard Jones, who analysed researches on the Internet and society. The report—The Impact of Digital Technologies on Human Well-being—concluded that there is no neurological evidence to suggest that the Internet is more effective at ‘rewiring’ our brains than other environmental influences. It also found that the Internet is a valuable learning resource and all forms of learning cause changes within the brain.

    There have been reports that the use of the Internet with its vast resources of information is changing the way people think and affecting their ability to concentrate. But Nominet said that’s scare-mongering（危言耸听）and the misinformation about the Internet use can potentially deny（否定）its benefits to people, in particular parents who are worried about the effects on their children’s development.

    The report also found that social networking sites, in themselves, are not a special source of risk to children, and are generally beneficial as they support existing friendships. In addition, playing action video games can improve some visual processes and motor response skills, while computer-based activity provides mental stimulation, and can help slow rates of cognitive decline.
